The management of pertrochanteric fractures (PTF) in the very elderly relies on early verticalisation to limit complications of the decubitus and this requires stable osteosynthesis allowing immediate full support without risk of mechanical failure. The aim of the study was to analyse the value of cementing the cervicocephalic blade during osteosynthesis with a proximal femoral nail. A prospective bicentric comparative study was con- ducted. Patients over 90 years of age with PTF were included. Centre A used a PFNA (Proximal Femoral Nail Antirotation) nail without blade cementing and Centre B used the same nail with blade cementing. The primary endpoint was the occurrence of disassembly of the osteosynthesis requiring revision surgery. Secondary endpoints were functional out- come (resumption of walking), postoperative pain and duration of surgery. Sixty-four patients were included in Centre A and 23 patients were included in Centre B. Mean age, gender, functional abilities before fracture, fracture type and tip-apex distance were comparable between the groups. Postoperative pain and duration of surgery did not show significant differences between the groups. Four patients operated on with an uncemented PFNA (6.25%) and one patient operated on with a cemented PFNA nail (4.35%) showed early dismantling. The rate of patients returning to walking was significantly higher in the cemented group (p=0.00005). No significant differences in the rate of dismantling were observed between the two groups. However, the group operated on with a cemented PFNA showed better functional recovery with a significantly higher rate of walking recovery.

Pediatric supracondylar humeral fracture is com- monly managed using closed reduction and per- cutaneous Kirschner wires pinning. However, there is no consensus on optimal pinning configuration in the literature. Our study aims to review the pinning configuration in our department, correlate our results with the available literature, and suggest the optimal configuration using basic biomechanics principles. We performed a retrospective review on children that were treated with K-wire pinning for supracondylar fracture at our institution between August 2017 and August 2019. Intra-operative antero-posterior view fluoroscopic images were used to measure the pin separation ratio (PSR), pin crossing angle (PCA), medial inclination angle (MIA) and lateral inclination angle (LIA). Pearson Correlation was used to identify the relationship between the variables. Ninety-one patients were included for analysis (39 male: 52 female), with a mean age of 6. Average PCA in the crossed pin and lateral-entry only technique CA was 75° and 12°, respectively. Mean crossed pin and lateral-entry only technique PSR is 0.54 and 0.17, respectively. There was a significant difference in both mean PSR and PCA between the configurations (p 0.33 and PCA >90° were best achieved in crossed pinning using 1 medial and 2 lateral pins. Assessing the biomechanical characteristics of the different fixation techniques, we have found that 2 lateral divergent pins and 1 medial pin using the crossed pin technique optimized both the PSR and PCA. We would recommend this configuration to optimize the stability of the fixation construct.

Segmental fractures of the femur are technically difficult to manage by intramedullary nailing, the gold standard treatment. We specifically describe minimally invasive plate osteosynthesis (MIPO) without floating segment fixation for this particular fracture pattern. Twenty patients with segmental fractures of the femur were operated on by the MIPO technique. Data were collected on operative time, postoperative complications, union times, and clinical outcomes. The mean operative time was 63.5 minutes (range 50-90). There were no peri-operative complications. All fractures were united with a mean union time of 16.1 weeks (range 12-20). Regarding postoperative malalignment, limb shortening was demonstrated in 4 patients, valgus angulation in 2 and varus angulation in 3. One patient had a bent plate with 7°varus angulation. According to the Thoresen score, 13 were determined to be excellent values, 6 to be good and 1 to be fair. MIPO without floating segment fixation is a safe and effective alternative for segmental fractures of the femur especially in circumstances that are unsuitable or unfeasible for intramedullary nailing.

Background. Retrospective study to examine secondary radial nerve palsy after humeral shaft fixation with closed locked intramedullary nailing. Materials and methods. Patients were identified from the hospitals’ registration systems for humeral shaft fractures, nerve lesions, plating, nailing and external fixation during a 10-year period from January 2007 to December 2016. All radial nerve lesions were registered and followed-up in patient files. Results. 89 patients with locked intramedullary nailing were available for an outpatient follow-up. Mean age was 67 years at the time of injury. 72 fractures were non-pathological. Of these, 31 were nonunions. 28, 61 and zero were identified in the proximal, middle and distal thirds of the humeral shaft respectively. 76 procedures were closed and 13 were with open reduction. Six radial nerves had nerve exploration. Eight patients developed immediate postoperative radial nerve palsies. Of these, six developed after closed surgery, two after nerve exploration. Of seven available patients with a radial nerve palsy, six of these remitted. Two patients were later surgically explored. One patient out of 89 sustained a verifiable permanent radial nerve paralysis. Conclusions. In this study, the risk of a radial nerve palsy was 7.9 % with closed locked intramedullary nailing. This study suggests that exploration of the radial nerve is not necessary routinely in order to prevent radial nerve lesions when performing closed intramedullary nailing for humeral shaft fractures in adults with a preoperative normal radial nerve function. Level of Evidence : Level IV.

The aim of the study is to compare the overall complication rate and in particular lag screw cut-out between the Trochanteric Gamma Nail and the Gamma 3 Nail. A total of 294 implants (Trochanteric Gamma Nail= 132 and Gamma 3 Nail=163) in 291 patients were analysed. All clinical data was obtained from the patients medical records. Subsequently radiographs were evaluated for fracture type according to the AO classification and lag screw position by determining the tip-apex distance, the Parker's ratio and the neck- shaft-angle. No significant differences in complication rates were found. The Parker's ratio was associated with lag screw cut-out : patients with medial cut-out had more a posteriorly placement (n=9, 3.1%), while patients with cranial cut-out had a more cranial placement of the lag screw (n=10, 3.4%). The tip-apex-distance and neck-shaft-angle were not associated with cut-out. The complication rate of the Gamma 3 Nail does not differ from the Trochanteric Gamma Nail. A lag screw positioning central or slightly inferior on the anteroposterior view and central on the lateral view is recommended.

This study evaluates the patient-reported functional outcome, clinical functional outcome and frequency of complications of simple oblique and transverse humeral midshaft fractures treated with a retrograde expert humeral nail. A retrospective cohort study of humeral midshaft fractures (AO 12-A2, 12-A3) treated with retrograde nailing between January 2010 and February 2018 in a level II trauma center was performed. Patients' perception of functional outcome was measured using the Disabilities of the Arm, Shoulder and Hand (DASH) scores. Thirteen patients with a median age of 20-years were treated with a retrograde nail. The median DASH score, administered 29 months (IQR 74) after surgery, was 7.9 (IQR 15.9). There were no perioperative frac- tures and the frequency of complications was 8%, being one nonunion. Retrograde nailing for humeral midshaft fractures is a safe technique, with excellent patient reported and clinical functional outcome. No iatrogenic peri- operative fractures occurred and the frequency of complications was low. We recommend the retrograde technique, if surgical fixation of humeral midshaft fractures is needed, especially in younger patients for who rotator cuff associated injuries will have a major impact on quality of life.

Despite the progress in tibial fracture care, some patients contract infection following intramedullary nailing. We analyzed which risk factors could predict infection in 171 tibial fractures. The independent variables included age, gender, body mass index, and comorbidities, along with external factors of fracture pattern, nailing settings, and treatment processing time. A multiple logistic regression was used to identify infection risk factors. The risk of infection significantly increased according to the open grading, the fractures' classification, time until antibiotic administration, and time until nailing. Gustilo type I fractures presented a higher rate of infection than expected, explained by a longer delay before surgery. The probabilistic equation allows infection prediction with high sensitivity and specificity. In total, we showed that no antibiotics' prescription in emergency service and a transverse fracture pattern were predictors of infection. An infection risk score can be computed, aiding surgeons in decision making. Outcomes could improve keeping these observations in mind. Level of evidence: Retrospective cohort study. Level iii.

A significant number of patients with pilon tibial fractures develop complications, the most devastating being a combination of infection and non-union with bone loss. The results of the Ilizarov bone transport technique were retrospectively evaluated in ten patients. All underwent an extensive resection and reconstruction aiming at an ankle arthrodesis. The outcome was registered by clinical and radiographic examination as proposed by Paley's functional and bone results classification. A good healing at the level of the docking site could be obtained in all patients but with a re- intervention in 8 of the 10. In 5 of these patients, re-intervention with a transcalcaneal nailing leaded to the final healing. Other options are debridement of the docking site (2 patients) and a new Ilizarov procedure (1 patient). If patients are prepared to participate in a long-term treatment with the risk of multiple interventions a reconstruction can be performed, resulting in a limb with an acceptable function, allowing all activities of daily life and even a professional occupation. To obtain this final result with a definite union at the docking site a secondary retrograde intramedullary nailing is considered a valuable and safe procedure.

Unstable trochanteric fractures and fractures with reverse obliquity pose difficulty in fixation. In recent years, intramedullary nails, for the treatment of comminuted and unstable intertrochanteric hip fractures, are becoming more popular relative to conventional, sliding hip screws. The purpose of our study was to evaluate the result of Trochanteric femoral nailing in comminuted, unstable Trochanteric femur fracture in terms of anatomical restoration and functional outcome. It is a prospective and without control study. Trochanteric femoral nailing has been done in comminuted unstable inter-trochanteric fracture femur (AO A2.2 to A3.3) of 25 patients and they are followed up postoperatively for at least 12 months. Pre-operative and post-operative clinical and radio-logical parameters are compared accordingly. Union in all cases. Overall complication rate 12% including some implant related complications. Functional outcome on Harris Hip Score is comparable with standard literature. For treatment of intertrochanteric hip fractures, particularly with comminuted fracture fragments, intramedullary devices offer beneficial features, such as closed insertion, a shorter lever arm, and controlled telescoping of the head-neck fragment. Insertion of the nail through the tip of the greater trochanter requires less dissection and may lead to less blood loss and fewer wound complications, as well as earlier postoperative mobility. Further biomechanical and clinical studies are necessary to validate the efficacy of the trochanteric femoral nail. Level of Evidence : Level III therapeutic study.

This study is aimed to compare the clinical and radiological differences between classic locked intra- medullary nailing (LIN) and blade expandable intra- medullary nailing (BEIN) at tibia shaft fractures. Operation time, exposing of radiation time and fracture healing times were recorded. Pain visual anolog scale (VAS), shortening of tibia and angulation of fracture line were compared. All patients healed. In LIN group operation time, exposing of radiation time was longer (statistically significant). Because of shorter operation time and lower radiation exposure we recommend the BEIN technique as a preferable technique in tibia intramedullary nailing.

The purpose of this study was to evaluate and compare the results of plate osteosynthesis, intramedullary nailing (IMN), and hybrid fixation for the treatment of both-forearm-bone shaft fractures in adults. One-hundred-one cases of both-forearm-bone shaft fractures were retrospectively reviewed. All fractures were divided into the following three groups, according to the method used for internal fixation : open reduction and internal fixation ORIF group (plate osteosynthesis), IMN group, and HYBRID group (plate osteosynthesis for the radius and intramedullary nail for the ulna). The results were assessed based on the time to union, functional recovery, restoration of the ulna and radial bow, operating time, complications, and patient satisfaction. In the ORIF, IMN, and HYBRID groups, the average union time was 10.8, 14.9, and 11.5 weeks, respectively. No intergroup differences were observed in the functional outcomes. The ORIF and HYBRID groups had a significantly better radial bow ratio compared to the IMN group. All patients in the three groups achieved union, with the exception of a single case of nonunion in the IMN group. ORIF and HYBRID fixation resulted in a more anatomical restoration of radial bow ratio, compared to the contralateral side. Such significant differences in the restoration of the radial bow had no effect on the final functional outcomes and minimal effect on forearm range of motion. Although there are statistically significant effects on the final forearm range of motion, the difference was only 5°. Thus, if the indication is properly selected, our results suggest that hybrid fixation would be acceptable and effective treatment options for both-forearm-bone fractures in adults.

Instability increases after fracture site resorption. This study aimed to compare the fracture site stabilities of different femoral nails after fracture site resorption. Thirty composite femurs were divided into three groups of 10 interlocking nails. Using axial compression-distraction machines and a custom-made torsion device, the fracture site rotational and axial stabilities after 1 mm fracture site resorption were determined. Between 6 Nm external and 6 Nm internal rotation torques, the means of the maximum fracture site rotation arc of motion were 5.94 mm for compression nails, 5.9 mm for interlocking nails and 3.5 mm for CAROT nails. Between 2300 N compression and 150 N distraction forces, the means of the fracture site axial motion were 3.15 mm for interlocking nails, 1.26 mm for compression nails and 1.26 mm for CAROT nails. CAROT nails are superior to compression and interlocking nails in fracture site rotational and axial stabilities after 1 mm fracture site resorption.

To determine reasonable treatment of intertrochanteric fractures with proximal femoral nail anti-rotation (PFNA) or hemi-arthroplasty (HA) in elderly patients. Between January 2009 and June 2013, a total of 367 patients were admitted to the Orthopedics Department of The Second Affiliated Hospital of Soochow University. Patient data were retrospectively analyzed and included 160 males and 207 females. The ages of the patients were between 60 and 97 years and the average age was 72 +/- 3.9 years. According to the Evans-Jensen classification scheme, the fracture types were type IA (n = 18), type IB (n =3 1), type II (n=154), and type III (n = 164). A comparison between the two surgical methods (PFNA and HA) included the duration of surgery, intra-operative blood loss, post-operative weight-bearing time, implant complications, and the Harris hip score. The data were analyzed after 14-50 months (average 24 months) of follow-up. The gender and age of the patients did not differ significantly between the two methods of treatment; however, the duration of surgery between the PFNA hemi-arthroplasty groups did differ (hemi-arthroplasty required less time), the intra-operative blood loss in the PFNA group was significantly less than the hemi-arthroplasty group, and the post-operative weight-bearing time was significantly shorter in the hemi-arthroplasty group than the PFNA group. A retrospective study was conducted in 367 patients during the 42-month study period (January 2009-June 2013) to observe the efficacy of PFNA and hemi-arthroplasty. Complete data were available for analysis. There are significant advantages and disadvantages with respect to the two surgical treatment modalities. For elderly patients with unstable fractures, severe osteoporosis, and pre-operative mobility, hemi-arthroplasty is preferred because hemi-arthroplasty has fewer disadvantages compared to PFNA, which is not suitable for full weight bearing and bone union. PFNA for the treatment of intertrochanteric fractures has been increasingly accepted and widely used; however the use of arthroplasty remains controversial (3). Conservative treatment for intertrochanteric fractures in elderly patients has become a main trend and often takes longer, gives rise to more complications, and has mortality rates higher than surgical treatment.

TThe aim of this study was to evaluate plate augmentation over previously inserted interlocking nails, combined with iliac bone grafting in treating aseptic femoral shaft non-unions. The research was conducted prospectively on 34 patients. A narrow dynamic compression plate was placed while the nail was retained. All the screws were directed posterior to the nail. There were 25 males and 9 females with mean age of 36.6 years old. The mean operative time was 95 minutes with 320ml blood loss. 28 patients showed solid healing by 6 months postoperatively (82%). By 8 months, all patients showed solid union (mean 6.3 months). Full range was regained in both hips and knees and all patients could walk bearing full weight without supportive devices by 8 months. Where non-union occurs over an interlocking nail, augmenting it with a plate and bone grafting appears to be an effective treatment method to obtain solid union.

In our country, the sliding Flexible Intramedullary Nailing is used alone or in combination with Ilizarov frame in children with osteogenesis imperfecta. The study assesses the results of sliding intramedullary nailing in deformity correction in severe types of osteogenesis imperfecta. We retrospectively reviewed 17 consecutive cases (mean age 5.2 y.o.) of types III, IV and VII of osteogenesis imperfecta. In group I (9 patients) the transphyseal FIN was performed using titanium nails. Sliding flexible intramedullary nailing was associated with Ilizarov frame in group II in 8 children. Patients in group I had overall complication rate of 88.9%: proximal nail migration (3), early secondary torsional displacement (4), non-telescoping (12), angular deformity (2), delayed or non-union (2). The reoperation rate was 100%. In group II we observed complications in 6 patients: nail migration (2), bowing of femur (2), non-telescoping (3). The reoperation rate was 87.5%. Flexible intramedullary nailing allows realignment and good functional outcomes. Its major disadvantage is an important complication rate and related reoperation rate. The use of Ilizarov frame provides additional stability and allows early weight-bearing.

The intraoperative determination of rotation in closed intramedullar nailing of tibial fractures is difficult. In this study, a more reliable method was used and it was a more practical means of checking rotation intra-operatively for tibia diaphysis fractures. 42 patients who presented with a unilateral tibia diaphyseal fracture. were randomly divided into two groups. In Group 1, the Intraoperative Rotation Control Method (IRCM) was used and compared with Group 2 as the control group. The Delta Rotation obtained from the MRI measurements were recorded and the Mean Delta Rotation (MDR) was obtained for each group separately. Malrotation was determined at a statistically significantly lower rate in Group 1. The MDR was statistically significantly lower in Group 1. This method does not require exposure to radiation like other radiological methods. Thus, the method used can be considered to be effective in the prevention of malrotation.

The purpose of this study was to describe our experience with a possible solution for implant- related irritation after intramedullary nailing of displaced midshaft clavicle fractures: the end cap. Ten patients with a displaced midshaft clavicle fracture were treated with intramedullary nailing and an end cap in 2013. Patients were followed in the outpatient clinic until fracture union. In 2015 patients were contacted again. Prospectively collected data included shoulder function and complications. The median follow-up time was 28.5 months (between 27 and 30 months). No patients were lost to follow- up. QuickDASH scores were 18.2, 9.1 and 2.3 after 6 weeks, 3 month and latest follow-up respectively. Nine patients (90%) had some type of implant-related complication. In three of these patients implant removal was required before union. One implant failure occurred which required major revision surgery using plate fixation. In conclusion, because in 70% of the patients the implant-related irritation was directly caused by the end cap, we believe end caps should not be used after intramedullary nailing for displaced midshaft clavicle fractures.

This study compared the standard technique with a less invasive technique for implantation of Sonoma Crx device in patients with displaced clavicle fractures. Patients were randomly allocated into two treatment groups based on the planned surgical method; Group 1 patients (n = 36) received the standard method whereas group 2 patients (n = 35) received the less invasive method originally developed by our team. Follow-up information included radiographic data, quick-DASH scoring, range of motion measurement and Constant shoulder score. The time of operation (p0.001) and mean time of fluoroscopy were significantly shorter (p0.001) in Group 1 vs. to Group 2. The mean time of hospital stay was significantly longer in Group 1 vs. Group 2 (p = 0.01). The time until bony union was slightly longer in Group 1 compared to Group 2 (p = 0.01). Sonoma Crx device can safely be implanted through a medial single incision with closed reduction.

Techniques for treating distal femoral aseptic nonunions associated with antegrade locked nail breakage are controversial. Each technique has unique advantages and disadvantages. Retrograde dynamic locked nailing was used in such treatment. Twelve patients with the described disorders were treated with retrograde dynamic traditional femoral locked nails. The proximal segment of the broken nail was removed from the hip area with the patient in the lateral decubitus position. Consequently, the patient was changed to the supine position. The distal segment of the broken nail was removed from the intercondylar inlet and a dynamic locked nail was inserted in a retrograde fashion. Two staples were used for reinforcing rotational stability whenever necessary. Early ambulation with protected weight bearing was encouraged. All 12 patients with 12 nonunions were followed for an average of 2.9 years (range, 1.1-4.7 years). All nonunions healed with a union rate of 100%, and the average time to union was 4.2 months (range, 3.0-5.5 months). There were no complications of nonunions, malunions or deep infection. Satisfactory knee function among 12 patients improved from 42% pre-operatively to 100% at the latest follow-up (p = 0.002). All 12 patients could walk without aids. The described technique may be an excellent alternative for treating a distal femoral aseptic nonunion associated with antegrade locked nail breakage. The technique is not difficult and the union and satisfactory rates are high.

The aim of this study was to compare the clinical and radiological results of InterTan nail and proximal femoral nail antirotation (PFNA) in the treatment of reverse intertrochanteric fractures (AO/OTA 31-A3). The study included a total of consecutive patients who presented at trauma centre with a reverse intertrochanteric fracture between in the last 7 years. Treatment was applied with PFNA in 33 patients and with InterTan nail in 36. Evaluation was made from the radiographs taken on postoperative day 1 and at the final follow-up examination of changes in the femoral neck and shaft angulation, measurement of telescoping of blade and lag screws and reduction quality. The mean telescoping was measured as 7.21±7.13mm in the PFNA group and 4.18±4.32 mm in the InterTan group (p = 0.039). Mechanical failure was seen in 8 (24.2%) cases in the PFNA group and in one case of the InterTan group. Cut-out was observed in 4 cases of the PFNA group and in none of the InterTan group. No statistically significant difference was determined between the groups in respect of time to union and functional scores (p = 0.573 and p = 0.294). The use of InterTan nailing in the fixation of reverse intertrochanteric fractures provided better clinical and radiological results compared to PFNA in terms of less telescoping, less change in the neck shaft angle and lower complication rates.

The purpose of the study is to assess the long term psychosocial functioning after height increase, using the external fixation then nailing method. Rosenberg Self-esteem scale and a questionnaire to assess social functioning were completed by 28 patients both preoperatively and at a mean follow-up of 7 years. The mean total score of RSE self-esteem for the 28 patients before lengthening was 21.5 (SD 1.03) (20-24). The mean total score of RSE for the patients 1 year after lengthening was 22 (SD 1.17) (20-24) with highly significant difference (p = 0.002).The mean total RSE self-esteem score after 7 years was 21.7 (SD 1.12) (21-25) with no significant difference (p = 0.11) Improvement was an evident in the short term self esteem after 1 year of follow up of the patients with height increase. On the other hand, there was an evident deterioration in the long term psychosocial evaluation during follow up after 7 years of height increase, returning to near pre-operative levels of self esteem.

The purpose of this meta-analysis was to compare the outcomes of external fixation and flexible intramedullary nails for femoral fractures in children between 5 and 15 years of age based on the current evidence.We searched relevent studies in the following database: Cochrane library, PubMed and EMABASE up to May 2014. All randomized controlled trials, Clinical controlled trials and retrospective controlled studies comparing external fixation and flexible intramedullary nails in femoral fractures of children were included. Data was extracted independently for meta-analysis.Seven trials altogether involving 338 cases of femoral fractures of children treated by external fixation (128 cases) and flexible intramedullary nails (210 cases) were included in the meta-analysis. Results showed that flexible intramedullary nails was superior to external fixation in less time to union , lower postoperative infection rate and refracture rate . It may not increase delayed union, Limb-length discrepancy , pain and bursitis . Both fixations obtained a similar patient satisfaction.Flexible intramedullary nail had greater advantages for the treatment of femoral fractures in children aged 5-15 years, compared to external fixation based on current meta-analysis. This conclusion will ultimately require rigorous and adequately powered randomized controlled trials to be proved.

The treatment of pathological fractures of the humerus caused by juvenile or aneurysmal bone cysts (JBC/ABC) should be a single approach with a high success rate and low complication rate. This study evaluates how day by day treatment concepts fulfil these aims. Children below 15 years of age with a pathological fracture of the humerus caused by a JBC or ABC between 01.01.2001 and 31.12.2010, were investigated by chart review in four major paediatric trauma centres. Age, gender, fracture localisation, X-ray findings, treatment and outcome - assessed by the Capanna classification (I to IV), were analysed. 60 children [41male, 19 female; mean age: 9 years (4-14 years)] with 43 JBC and 12 ABC were included as well as five cysts, who could not be classified definitively. First treatment was non-operatively in 33 children. Of these 27 cysts did not improve; likewise the supportive installation of cortisone in six patients did not change the outcome. The first treatment consisted of elastic stable intramedullary in 13 children; up to three nail exchanges included. But only six of these reached (nearly) complete resolution (I/II). Overall the combined mechanical and biological treatment with curettage, elastic stable intramedullary nailing, (artificial) bone substitute and in some cases growth factors was performed as the 1st-line treatment in nine patients and further in 2nd or 3rd-line treatments in 13 humeral cysts. More than half of these reached a complete or nearly complete resolution of the cyst (12x I, 5x II, 1x III, 4x IV). Major complications in all operated patients were six nails not removable and two children with upper extremities length differences. Healing rates are low for non-operative treatment, elastic stable intramedullary nailing alone and by using cortisone for cysts resolution in pathological fractures of the humerus. Data support a combined mechanical and biological treatment with curettage, elastic stable intramedullary nailing, (artificial) bone substitute and the use of growth factors.

The purpose of this study is to present our experience of treating adolescent femoral fractures using a locked intramedullary nail with a lateral trochanteric entry point. We retrospectively reviewed 15 femoral fractures in 13 adolescents who were treated in our unit between 2011 and 2014. Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, time to union and complications. A radiographic review was also undertaken. The mean time to radiological union in 14 out of the 15 fractures was 13 weeks (range, 10-20 weeks). One patient had a delayed union that required bone grafting and united finally at 30 weeks post injury. The mean difference in the neck shaft angle between the operated and non-operated side was 1.5 degrees (range : -10 to 10 degrees). No patients had infection or avascular necrosis. Five nails were removed after the fractures had healed without complications. Locked rigid intramedullary nailing of adolescent femoral fractures is a safe and effective treatment option when the lateral aspect of the greater trochanter is used as an entry point.

The aim of this study was to compare two proximal femur nails with regard to the complication rate and midterm clinical outcome : the InterTAN nail (ITN) versus the third generation gamma nail (GN). 78 patients older than 60 years with an unstable intertrochanteric femoral fracture (AO/OTA 31 A2/A3) were randomised over a 20 month period into either ITN (n = 39) or GN (n = 39). The outcomes of interest were the perioperative implant-related complications and the functional status (Harris Hip Score) at 6 months postoperatively. In 14 of the ITN and in two of the GN procedures the surgeons rated the implant as cumbersome (p = 0.002). Functional outcome and complication rate did not differ between both groups. The mechanical failure correlated with the positioning of the lag screw independent on the used implant. The surgeon's technique (closed reduction, positioning of lag screw) and not implant configuration, is of crucial importance in achieving successful outcome.

Atypical femoral fractures have been associated with long term use of bisphosphonates. Our study plan was to report the outcome of treatment for a series of -patients with an atypical femoral fracture and to compare the characteristics of those patients with a proximal femoral fracture. 21 atypical fractures were identified over a seven year period and these were compared with those of 2.547 hip fracture patients treated over the same time period at a single centre. The mean age of patients with an atypical fracture was on average nine years less than that for the hip fracture patients (72 as against 81 years, p = 0.002). Four (19.0%) of the patients with atypical fracture had no injury associated with the fracture and nine (42.9%) patients had pain prior to presentation at hospital for a mean of 31 days. Patients with atypical fractures were more likely to be smokers (9/21(42.9%) versus 319/2547 (12.5%), p = 0.0001) and more likely to be on long term oral steroid therapy (8/21 (38.1%) versus 131/2547 (5.1%), p 0.0001) in comparison to other hip fracture patients. All the atypical fractures were treated by intramedullary nailing and healed uneventfully apart from one fracture that developed non-union requiring revision nailing. Residual pain at one year from injury was more prevalent for patients with atypical fractures.

Aim of the present study was to compare the outcomes between exchanging reamed nailing (ERN) and augmentative compression plating (ACP) in treatment of femoral shaft nonunion after intra-medullary nailing (IMN) retrospectively. A retrospective, multicentre study was performed with 188 patients (190 cases)with femoral shaft nonunion after IMN, who received therapy with either ERN (n = 92) for 44/92 (47.8%) cases of nonisthmal nonunions and 48/92 (52.2%) cases of isthmal nonunions or ACP (n = 98) for 48/98 (49%) cases of nonisthmal nonunions and 50/98 (51%) cases of isthmal nonunions. Operation time, intraoperative blood loss, time to union, union rate, postoperative draining volume and complication rate were compared between ERN and ACP group. After a mean follow-up of 4.6 years (range 1-8.1 years), the bone union occurred in 98/98 (100%) cases in -total ACP group versus 80/92 (87%) cases in total ERN group [odds ratio (OR) = 3.34, 95% confidence interval (CI) 0.8-1.6]. Twelve cases with re-nonunion in the total ERN group included 10/12 (83.3%) cases of nonisthmal nonunions and 2/12 (16.7%) cases of isthmal nonunion with cortical bone defect 3 cm. The average time to union, the intraoperative blood loss and the complication rate in total ERN group were also both significantly more than that in total ACP group (p = 0.031, p = 0.042, p = 0.028). No -significant difference was found in the average operation time between the two total groups (p = 0.213). However, for nonisthmal nonunions, the mean operation time for ERN group was 126.8 ± 19.6 min in -comparison to ACP group (88.6 ± 15.2 min), significant difference was found between ERN group and ACP group (p = 0.021). ACP could obtain the higher bone union rate and shorter time to union than ERN in the treatment of femoral shaft nonunion after failed IMN. Especially for nonisthmal femoral shaft nonunions or isthmal.

The main complications of open tibiotalocalcaneal arthrodesis are wound healing disorders and nonunion. Our hypothesis was that arthroscopy and interlocking intramedullary nailing decrease these complications. We retrospectively reviewed six patients (mean age: 58 years; mean preoperative Kitaoka score: 51/100) having undergone arthroscopic tibiotalocalcaneal arthrodesis with retrograde intramedullary nailing between January and November 2011 for equinus deformity of the hindfoot and subtalar instability of neurological origin. Postoperative pain disappeared completely in four cases, one patient presented some pain associated with projection of the proximal locking screw head under the skin and the remaining patient presented fibular tendinitis that resolved after infiltration of anti-inflammatory drugs. The mean postoperative Kitaoka score was 64/100. None of the patients presented any wound healing complications or nonunion. The observed incidence of wound complications and bone consolidation disorders after tibiotalocalcaneal arthrodesis was lower than the ones reported for open tibiotalocalcaneal arthrodesis. Level of clinical evidence IV: retrospective case series.

The treatment of basicervical femoral fractures remains controversial. The aim of this study was to examine the efficacy of intramedullary nail use in the surgical treatment of basicervical fractures. In total, 28 patients with basicervical fractures treated with proximal femoral nails were examined retrospectively. Fracture healing was observed in all patients, who were followed at least for 6 months. While the average radiological fracture healing timing was ~10.5 (8-14) weeks, clinical fracture healing occurred in 6 (5-9) weeks on average. Screw cut‑out, avascular necrosis, femur fracture, and surgical wound infections did not occur in any patient. Severe collapse (10%) was not noted in any patient. The postoperative mean Harris hip score was 81.2±21.3. Osteosynthesis application with a proximal femoral nail in basicervical proximal femur fractures is a surgical treatment that can be performed with minimally invasive techniques without open surgery. This is a rapid, sound, and simple treatment method with low morbidity.

Open reduction and internal fixation of fracture clavicle has typically been done by variable types of plates. Plates carry the disadvantages of longer incisions, prominence of the plates and wound complications. The purpose of this study is to present an alternative surgical technique for acute midshaft clavicular fracture using cannulated 6.5 screws with minimal incision over the fracture site. Twenty seven adult patients with acute midshaft clavicular fractures were surgically treated with mini open technique using 6.5mm cannulated screws. The modified shoulder rating scale by Chuang was used for outcome evaluation. Union occurred in a mean of 8.3 weeks range 6-12 weeks. Restoration of clavicular length was achieved in all cases. Twenty-four patients experienced no pain on all activity at latest follow-up. All patients expressed their willingness to have the surgery again should they have the same problem. One patient stated that she would not have the surgery again.reduction and internal fixation with a cannulated screw is an alternative economic technique for the treatment of acute midshaft clavicular fractures that is useful in selected cases where surgery is indicated.

Metastases in the proximal femur and in the femoral diaphysis are usually treated with either cephalomedullary or intramedullary nailing. The benefit of curettage and augmentation of the nail with methyl methacrylate remains controversial. The authors retrospectively studied the outcomes with cephalomedullary and intramedullary nailing without curettage and methyl-methacrylate augmentation for lytic metastases of the proximal/diaphyseal femur. Twenty-one complete (11) or impending (10) pathological fractures in 19 consecutive patients were treated between January 2006 and August 2013. There were 11 women and 8 men. Their mean age was 62 years (range, 38 to 87). All patients received adjuvant chemotherapy or radiotherapy.The average postsurgical survival was 9.7 months (range 1-36 months). A single deep infection was debrided. Seventeen out of 19 patients were ambulatory, with or without a walking aid. No implant failure was noted. In other words, patients succumbed to the disease prior to hardware failure. Femoral nail insertion without curettage and cement augmentation provided satisfactory stabilization of proximal and diaphyseal femur fractures, impending or complete, even when there was massive bone destruction.

The treatment of massive tibial bone defects takes a very long time. An Ilizarov trifocal approach decreases the lengthening time. Subsequent intramedullary fixation decreases the complications of the conventional Ilizarov method. This technique was applied between June 2010 and June 2011 in 10 male patients with a mean age of 30 years. All had grade III open tibial fractures. The patients were treated at Mansoura University Hospital and a private hospital. The sequence of treatment included trifocal lengthening using the Ilizarov method, followed by removal of the fixator, temporary plaster cast immobilisation and subsequent intramedullary fixation until complete union was achieved. The length of the tibial bone defect ranged between 6-12 cm; the lengthening time ranged between 45-75 days and the consolidation time ranged between 90-160 days. The results were evaluated according to Paley's bone and functional assessment scores. The bone results were excellent in 7 patients and good in 3. Two patients had non union and one patient had pin tract infection. The functional results were excellent in 7 patients and good in 3. Two patients had equinus deformity and one patient had limited range of knee motion. There were no deep infections, DVTs or leg length discrepancies greater than 2.5 cm. Ilizarov trifocal lengthening followed by delayed intramedullary fixation appeared in this study as a good method of treatment for massive posttraumatic tibial bone defects. It reduced fixator time and minimized the complications associated with the Ilizarov fixation.

This study aimed to compare the efficacy of two treatment modalities for periprosthetic supracondylar fractures. The results of intramedullary nailing in 7 patients and locked plating in 9 patients were reviewed retrospectively. Mean follow-up was 4.3 years (range : 1 to 13 years). One patient died on the first postoperative day. Union of the fracture was achieved in the other 15 patients, after a mean time of 3.86 months: 3.9 months (range: 3 to 6 months) in the locked plate group and 3.86 months (range : 3 to 5 months) in the intramedullary nail group (p = 0.96). Mean Knee Society Score was 78 points (range : 68 to 84 points) and mean total knee range of motion was 82 degrees (range 70 degrees to 90 degrees) with no significant differences between groups. Sagittal and coronal plane measurements were similar both in the early postoperative period and at the last follow-up. The two treatment modalities had similar results with a high success rate.

The authors retrospectively studied 43 children with femoral fractures, treated with titanium elastic nailing (TEN). Twenty-two underwent closed fluoroscopic reduction ( Group I), whereas the other 21 underwent mini-open reduction (Group II). The operation time averaged 71 minutes in group I, and 48 minutes in group II (p0.001). The mean fluoroscopy time was 793 seconds in group I, and 35.5 seconds in group II (p0.001). However, blood loss and hospital stay were significantly higher in group II (p0.001 and p = 0.001 respectively). Time to full weight bearing, time to radiographic union and TEN outcome score did not differ significantly. Overall, no one technique was really superior. From a practical viewpoint, a mini-open reduction may be decided intra-operatively if closed reduction proves to be problematic. This decreases intra-operative radiation and length of the surgical procedure.

There is still debate about the proper treatment of completely displaced metaphyseal fractures of the distal radius in children. Although historically these fractures were treated by closed reduction and casting, some authors have reported that up to 25% of these injuries re-displaced early in the cast despite good initial reduction. Since 2000 we have used closed reduction and percutaneous stabilisation with a short intramedullary wire, using a percutaneous technique, in children with completely displaced metaphyseal fractures of the distal radius. We retrospectively analysed the records of 100 children who were treated in our departments during a six-year period (2000-2005). Of these, 45 had early re-displacement of their fractures after an initial conservative treatment. Our results suggest that closed reduction and short intramedullary wiring of these injuries allows adequate stabilization, maintains the alignment in the cast, reduces the need for follow-up radiographs, with a low rate of infections and complications, while healing occurs.

Retained intramedullary femoral nails can pose a problem for the implantation of the femoral component during total hip arthoplasty (THA) and they must often be removed. A patient with a retained Küntscher femoral nail implanted 47 years previously presented in our outpatient clinic for a THA. Since removal of the nail was impossible without severe damage to the femur, we chose to perform an extended trochanteric osteotomy, to cut the proximal part of the nail and to implant a cemented short stem with its tip in the hollow end of the nail.

In intramedullary tibial nailing, multi-planar locking makes stabilization of proximal and distal metaphyseal fractures possible. A known complication in intramedullary nailing of the tibia is iatrogenic injury to neuro-vascular structures caused by the insertion of locking screws. As shown in previous studies, the distal positioning of the nail is important, as it determines the course of the locking bolts. The goal of the present study was to display the consequences of posterior nail malpositioning with respect to the safety of the distal medio-lateral locking screws and the available options. Human cadaveric legs were plastinated according to the sequential plastination technique after intramedullary nailing of the tibia and were then cut transversely. The tibial nails were placed centrally or posteriorly. Macroscopic analysis showed a distinct drawback of posterior nail positioning, with diminished options for the placement of the locking screws and thereby a risk of damaging the anterior and posterior neuro-vascular bundles by distal medio-lateral locking screws.

Interlocking intramedullary nailing is currently the preferred treatment for most tibial fractures requiring operative treatment, with good results and a relatively low complication rate as reported in large clinical series. However, vascular and neurological complications caused by interlocking screws have been reported. In addition, insertion of distal interlocking screws can be technically demanding and may entail substantial exposure. We present the results with an expandable self-locking nail in the management of 52 AO type A and B tibial shaft fractures. The mean time to union was 15.8 weeks and the rate of union was 98%. The average surgical time was 60 minutes. Complications were those usually seen in diaphysis nailing and no complication was noted during nail expansion. Interlocking screws are not necessary, which reduces the risk of iatrogenic lesions. The expandable nail allows effective management of AO type A and B diaphyseal fractures of the tibia, a lower radiation exposure and shorter operative time.

The purpose of this study was to compare the results of external fixation alone versus external fixation combined with intramedullary nailing in the reconstruction of segmental defects of the tibia resulting from chronic osteomyelitis. Thirty-two patients were treated with external fixation alone and 17 patients with the combined technique. Surgical reconstruction utilised distraction osteogenesis by focal segment transport after infection was eradicated. In the external fixation group, the mean size of the defect was 724 cm, external fixation index was 56.32 days/cm and consolidation index was 40.09 day/cm. In the combined technique group, the mean size of the defect was 8.89 cm, external fixation index was 1631 days/cm and consolidation index was 25.7 days/cm. There was no difference in non-union, deformity, limb length discrepancy (LLD), bone and functional results. However, there was a higher rate of reinfection in the combined group when tibial lengthening exceeded 9.25 cm and lengthening ratio was more than 24.8%.

Eleven patients with aseptic non-union of a distal metaphyseo-diaphyseal femoral fracture after intramedullary interlocked nailing were treated by wave plate fixation and an interposed tricortical iliac strut graft with the nail in situ. Complete clinical and radiological union occurred in all cases in a mean period of 7.5 months (range: 7-10). Augmentative wave plate fixation with a tricortical iliac strut graft is a biological and simple solution for non-union of the distal diaphyseo-metaphyseal femoral shaft fracture following an intramedullary locked nail fixation. No special instrumentation is required. In spite of early weight bearing, it led to bony union in a reasonable delay in all the patients reported.

Metastatic lesions often occur in the trochanteric region of the femur with a risk for pathologic fractures, requiring aggressive surgical treatment. We present two cases of mechanical failure of the Titanium Gamma 3 Nail 180 used for treatment of impending pertrochanteric pathologic fractures. Metallurgic and low power optical examination findings are presented. Treatment with intramedullary nailing devices has proven its efficacy. However in cases of delayed union or non-union, a fatigue fracture due to dynamic overload should be expected sooner of later. If there is no evidence of healing within six months postoperatively a hardware exchange or another therapeutic option should be considered.

We report the results of a prospective randomized clinical trial comparing the Gamma 3 nail with the ACE trochanteric nail for the treatment of pertrochanteric femoral fractures. One hundred and twelve consecutive patients were enrolled in the study: 61 patients were treated with the Gamma 3 nail, 51 with the ACE trochanteric nail. The two groups were matched for age, fracture type and preoperative Merle d'Aubigné hip score. All patients were followed up clinically and radiographically on a regular basis between 6 weeks and one year postoperatively. Twenty-six patients (23%) died within the first postoperative year. Six patients were lost to follow-up. In each group, two patients were revised due to mechanical failure. Nonunion did not occur. The mean postoperative hip scores in the Gamma 3 and the ACE group were 14.19 and 14.12 respectively, with no significant difference (p = 0.92). Walking ability was adequately restored in approximately 80% of the patients. Both implants appeared as safe and effective methods of treatment for intertrochanteric hip fractures.

The purpose of this retrospective chart and radiographic review is to describe an effective reduction technique during intramedullary nailing of distal metaphyseal tibia fractures with the use of a pointed percutaneous clamp. Between 2007 and 2010, 100 patients who sustained 102 tibia fractures were definitively treated with an intramedullary nail at one of two medical centers. Diaphyseal fractures and injuries with an associated disruption of the distal tibiofibular joint were excluded from our study. A total of 27 patients with 27 distal metaphyseal tibia fractures (OTA types 42-A, 43-A, and 43-B) were included. All 27 patients underwent IM nailing of their fractures with anatomic reduction achieved using a percutaneously placed pointed reduction clamp prior to insertion of the IM implant. Fracture alignment and angular deformity was assessed using goniometric measurement functions on the PACS system (GE, Waukeshau, WI) obtained from preoperative and postoperative anteroposterior and lateral images for all subjects. Malalignment was defined as more than 5 degrees of angulation in any plane. Fourteen of the fractures were classified as OTA 42-A, 9 were OTA 43-A, and 4 were OTA 43-B. Analysis of post-closed reduction, preoperative anteroposterior radiographs revealed a mean of 7.9 degrees of coronal plane (range: 0.9 degrees-26 degrees) angulation. Post closed reduction preoperative lateral radiographs revealed a mean of 6.8 degrees sagittal plane (range: 0 degrees-24.6 degrees) angulation. Postoperative anteroposterior and lateral radiographs showed the distal segment returned to its anatomical alignment with a mean angulation of 0.5 degrees (range, 0 degrees-3.5 degrees) and 0.7 degrees (range, 0 degrees-4.2 degrees) of varus/ valgus and apex anterior/posterior angulation, respectively. These results showed an acceptable postopertative alignment in all 27 distal third fractures. No intra-operative or postoperative complications were noted in the study group. This study suggests that the use of percutaneous clamps during intramedullary nailing of distal metaphyseal tibia fractures is an easily-reproducible and effective method of reduction with no associated intraoperative complications.

Intramedullary nailing of proximal tibial fractures can be difficult when using the standard entry portal. We evaluated the suprapatellar portal, using a midline quadriceps tendon incision, to perform intramedullary nailing of the tibia. Seven patients were treated with this adaptation of the standard intramedullary nailing procedure. An arthroscopy was done before and after the nailing procedure. No special equipment was used to perform the intramedullary nailing. We evaluated the handling and necessary modifications of the standard intramedullary technique to introduce the locked tibial nail through the suprapatellar approach. We found this technique not necessarily more difficult than the standard intramedullary nailing of the tibia through the infrapatellar entry portal. Although the patients did not complain of patellofemoral discomfort after the suprapatellar nailing, definitive scuffing of the cartilage in the lower part of the femoral trochlea was visible. Introduction of a locked tibial nail via the suprapatellar approach was found to be possible and even advantageous for some complex upper tibial shaft fractures in compromised limbs. Some possible downsides of this approach need to be taken into account but, in some cases, they can be outweighed by the benefits.
