Retrograde intramedullary nailing (RIMN) is the favored over antegrade intramedullary nailing in fractures of the distal femur. It provides a longer working length and allows for multiple distal screw insertion and therefore a more stable construct. Concerns remain regarding the violation of the knee cartilage and the effect this has on knee function. Many studies have shown high incidence of knee pain with reports varying from 20 to 86%. We describe a novel technical trick aiming at partially restoring the knee cartilage of the operated side and decreasing the hemorrhage stemming from the medullary canal. Our experience of the technique and the case series shows that closing the entrance point of the medullary canal after a RIMN procedure leads to better function and less knee pain in the postoperative period.

Intertrochanteric femur fractures (ITFF) are frequently fixed with proximal femoral nailing (PFN), and a common cause of fixation failure is cut-out of the lag screws. In the literature, many factors have been defined to determine the failure risk, including the tip–apex distance (TAD), calcar-referenced tip–apex distance (CalTAD), the Cleveland zone and Parker's ratio. In this study, a novel technique is described which favors infero-posterior placement of the lag screw and predicts failure risk for PFN. The purpose of this study was to evaluate the tip–neck distance ratio as a factor for the prediction of cut-out after PFN of ITFF. A retrospective evaluation was made of the data of 125 patients applied with PFN for ITFF between October 2016 and September 2019. The occurrence of mechanical complications was analyzed in relation to age, gender, fracture side, American Society of Anaesthesiologists classification, fracture classification, reduction quality, bone quality, Cleveland zone, Parker’s ratio, TAD, CalTAD and the TNDR. A total of 125 patients, including 16 with mechanical complications, were suitable for full analysis. In the univariate analysis, reduction quality (p = 0.003), the TAD (p = 0.048) and the TNDR (p = 0.030) were statistically associated with mechanical complications (p

The posterior tibial slope (PTS) is an important factor in patients undergoing unicondylar knee arthroplasty. It is an area subjected to high shear and compressive forces. Our objective is to investigate the changes taking place on the tibial slope of cementless unicondylar knee arthroplasties and define its relationship with functional scores.Patients undergoing a cementless unicondylar knee arthroplasty between January 2011 and July 2019 were selected. Exclusion criteria were lack of at least 1 year of follow up, loss to follow-up for any reason, and revision of a metallic component. Overall, 161 cases were included. Patients were analyzed using standard radiographs for changes in PTS, coronal positioning of the implant, and overhanging. Function was analyzed using Oxford Knee Score, Tegner Activity Scale, and Knee Society Score. Changes of the PTS were analyzed for statistical significance and for correlations with all the other variables.All postoperative functional scores showed significant improvement (P.05). Compared to the early postoperative values, increases of ≤5° were detected in 79% of all patients. The greater amount of slope change occurred during the first 6 months postoperatively. Statistical analysis revealed no significant relationship with functional scores of the knee, age, body mass index, overhanging, and coronal alignment of the tibial component.This study showed that, with time, minimal changes take place in the PTS of cementless unicondylar knee arthroplasty. The change mostly takes place during the first 6 months. These changes do not affect functional scores.

Background and objective Unicondylar knee replacement (UKR) is one of the most frequently performed arthroplastic operations worldwide. Migration and subsidence regarding the tibial component of UKR is a well-known phenomenon. In this study, we aimed to analyze whether plain radiographs are a reliable means to measure the true coronal and sagittal alignment of the UKR’s tibial component. Methods Patients undergoing a UKR procedure at our center between December 2020 and March 2011 were eligible for this study. Inclusion criteria were as follows: the presence of well-aligned standard and reproducible anteroposterior and lateral X-rays taken one week before or after a low-radiation artifact-reduced CT scan. Sixty-six knees were included in the study. Coronal and sagittal alignment of the tibial component was measured in a standard manner by two observers on both X-rays and CT scans. A correlation analysis was performed, and the margin of error was established. Results Intra-observer reliability was high among the two observers whether for X-ray or CT scan measurements [intraclass correlation coefficient (ICC): >0.900]. On the other hand, coronal plane measurements had lower inter-observer ICC values on both X-rays and CT scans while reliability on the sagittal plane was higher. There was a high correlation between radiographic measurements on X-rays and CT scans on both planes. Conclusion Even though the measurements on plain radiographs were slightly different from the ones obtained from CT scans, the correlation between them was very strong. Caution should be exercised when measuring the coronal alignment of the tibial implant on X-rays since it is more frequently affected by rotational misalignment.

Aim: Leg length discrepancy (LLD), instability and periprosthetic infection are most common reasons patient complaint after total hip replacement (THR) surgery. Degree of soft tissue release in operating room may mislead us about LLD. The objective of this study is to report the effect of the anesthesia type on leg lengthening amount.Material and Method: In this study, 36 primary coxarthrosis patients who underwent THR surgery in two different medical centers under different types of anesthesia during2016-2017 were enrolled retrospectively. Patients are divided into two groups. Group 1 (n:18) who underwent general anesthesia, group 2 (n:18) who underwent regional anesthesia. Distance between greater trochanter-ischial tuberocity (GT-IT) is measured radiologically for leg lengthening, umbilicus-medial malleolus distance is measured clinically for LLD. Harris hip score (HHS) is measured for functional scoring.Results: The average follow-up time was 13 months (12-15 months). No deep infection or neurovascular damage were seen in patients. According to GT-IT distance, leg lengthening was 19.76±9.83 mm in group 1 and 3.2±3.96 in group 2 (p:0.000*). According to 12 month umbilicus-medial malleolus distance, 9 patients experienced leg lengthening (, Amaç: Total kalça artroplastisi sonrası ekstremite eşitsizliği, instabilite ve enfeksiyondan sonrası en sık hasta şikayet nedenidir.

This study aims to investigate clinical and functional factors in patients undergoing unilateral and simultaneous bilateral total knee arthroplasty (TKA) who were classified into subgroups of nonobese, obese, and morbidly obese, and to determine perioperative and postoperative complications. We conducted an evaluation of 489 nonobese, obese, and morbidly obese patients who underwent TKA due to primary knee osteoarthritis between January 2006 and December 2013. The arthroplasties were performed by three different surgeons. Patients who underwent unilateral (group 1) or simultaneous bilateral (group 2) TKAs were divided into subgroups in accordance with BMI levels, that is, (a) nonobese (BMI 0.05), except for morbidly obese patients. Most intraoperative and early postoperative complications occurred in the morbidly obese group, especially in those undergoing simultaneous bilateral TKA procedures (p

Background The aim of this study was to apply cross-cultural adaptation and validity assessment to the Turkish translation of the Japanese Orthopedic Association Back Pain Evaluation Questionnaire applied to patients conservatively monitored for lumbar disc hernia and narrowing of the lumbar canal. Methods The questionnaire was translated into Turkish based on guidelines. In respect of the comprehensibility of the obtained pre-final version of the questionnaire, a pilot test was applied to 20 healthy individuals. The patients were requested to complete the final version of the questionnaire after an orthopedic and physical therapy assistant doctor (resident) had completed the diagnosis and demographic information. To evaluate the retest reliability, the test was applied a second time, 14 days (±3 days) after the first application, again in the Orthopedics and Physical Therapy Outpatient Clinic. Results The study was completed with a total of 215 individuals, comprising 107 patients and 108 healthy volunteers. When Turkish version of the questionnaire scale was evaluated of the patients and healthy volunteers together, the internal consistency was determined at the levels of Cronbach's α excellent. The lowest correlations of all the questionnaire scale items with the scale sub-dimensions was at the level of r = 0.509, which demonstrated that there was a sufficient validity level of the Turkish translated questionnaire scale. A statistically significant direct correlation at a high level was seen between the pre and post points in all the scale sub-dimensions. Conclusions The results of the current study showed that Turkish version of the questionnaire had sufficient reliability and validity in the evaluation of low back pain and resulting dysfunction and disability in patients with LDH and narrowing of the lumbar canal.

The hypothetical basis of this trial specifies that hemiarthroplasty applications without cement will prove to be superior to applications with cement in terms of survival, complications, clinical and radiological improvements in the early stages of femoral neck fracture cases, which belongs to the Society of Anesthesiologists (ASA) class III group. Society of Anesthesiologists (ASA) class III elderly patients (minimum 70 years of age), who had undergone surgical interventions for femoral neck fractures were classified into two groups as those undergoing the intervention without cement (Group A) and those undergoing the procedure with cement (Group B), and these were retrospectively evaluated. The patients were followed up for a mean duration of 47.4 and 44.8 months, respectively. Survival in the early stage, duration of stay in the intensive care, intraoperative cardiac indexes, complications, clinical and radiological parameters were the main factors used in the evaluation and comparisons. The mean duration of operation in Group B cases was determined to be statistically significantly longer than that of Group A (p

Background. Puerperal diastasis of the pubic symphysis is a rare intrapartum complication. This report presents the case of a woman who experienced synchronous pubic symphysis and sacroiliac joint separations induced by vaginal delivery.Case. A 32-year-old woman (gravida 2, parity 2) with an uncomplicated prenatal course developed acute-onset anterior pubic pain during vaginal delivery. The pain persisted postpartum and was exacerbated by leg movement. Physical and radiographic examinations showed a pubic symphyseal separation of 2.4 cm, accompanied by a 10 mm disruption of the left sacroiliac joint. The patient was treated conservatively with pain-relief medication; bed rest, mostly in the left lateral decubitus position; closed reduction and application of a pelvic binder; use of a walker; and physical therapy.Conclusion. The patient responded to conservative management. She was essentially pain-free and regained movement and ambulation by 12 weeks postpartum.

Objective To evaluate the viability and integrity of fresh frozen bulk femoral head allografts obtained from the institutional bone bank that were used to reconstruct severe acetabular defects and to validate the SPECT/CT method which gives both anatomical and functional data for this purpose. Methods We retrospectively reviewed 9 patients (6 female, 3 male; mean age 63.6 years). Preoperative and postoperative leg lengths, existence of the Trendelenburg sign, range of motion of the hip, visual analogue score (VAS), Harris Hip Score (HHS) and any complication were assesed at each follow-up. Radiographically, position of the cup, signs of loosening or migration, and union of the graft were all determined. At the latest follow-up, patients were evaluated with hybrid SPECT/CT. Results The average duration of follow-up was 38.1 months (24-50 months). The overall mean HHS and VAS scores were significantly improved (pConclusions Institutional bank allografts are still excellent options for treating large acetabular defects in revision total hip arthroplasty where trabecular metals are not available or in common use. The Hybrid SPECT/CT method is a reliable, noninvasive method for evaluating both the integrity and viability of a bulk graft in 3-D.

This retrospective study enrolled 526 patients undergoing bilateral total knee arthroplasties at our institution. In nondrainage group (Group 1) of 255 patients (510 knees), a disposable elastic sterile exsanguination tourniquet (HemaClear), wound closure in layers and Jones Bandage, without pre-tourniquet removal hemostasis or Hemovac drain were used. In drainage group (Group 2) of 227 patients (454 knees), pneumatic tourniquet, post-deflation hemostasis, a Hemovac drain and Jones bandage were used. The maximal drop in hemoglobin was significantly greater in Group 2 than Group 1 (P0.001). Also infection rate was significantly lower in Group 1 (P = 0.017). The use of sterile tourniquet removed after wound closure without Hemovac drain decreases blood transfusion need, infection rate, tourniquet related pain and postoperative complications.

Large bearing metal-on-metal (MOM) total hip arthroplasty (THA) may offer advantages relating to stability and range of motion in patients with Crowe Type I and II developmental dysplasia of the hip (DDH). The purpose of this study was to provide an analysis of the clinical and radiological results of MOM THA in this context and compare the results with a cohort of patients treated with metal-on-polyethylene (MOP) bearing surfaces. 75 hips in 65 patients were treated with cementless MOM THA using large femoral heads (36–56 mm). The mean age of the patients was 47.4 years (29 to 59) and 54 were female. A group of 47 hips (41 patients) treated with conventional THA (screwed cup-polyethylene insert-28mm head) was used for comparison. The study group was followed up for a mean of 62.1 months (32 to 76). No difference was found between the two groups in relation to improvement in Harris hip score (HHS) (43.1 to 90.3 points in the study group, 42.6 to 89.5 points in the control group, p>0.05). Although the preoperative range of motion in all planes were similar in both groups, the large head group demonstrated greater motion in all planes postoperatively, which was significant (all p=0.001). Additionally, there was a significant difference between groups in relation to the necessity for acetabular structural graft (8% and 31.9%, respectively; p=0.001). No major complications or adverse reactions to metal debris (ARMD) were observed in the study group. The results of large head MOM THA in young and active patients with DDH are similar to conventional THA at early follow-up, but the former offers the advantages of secure acetabular fixation without screws, greater range of motion, and lower risk of dislocation.

The apparent synovial hypertrophy in some cases of noninflammatory knee osteoarthritis suggests that total synovectomy may provide beneficial inflammatory and pain relief after total knee arthroplasty. The aim of the study was to compare the effect of synovectomy on the postoperative pain, bleeding and functional outcome after surgical treatment of knee osteoarthritis. A total of 50 patients with bilateral, non inflammatory, primary knee osteoarthritis were included in the study. Bilateral total knee replacement was performed at the same session. Total synovectomy and total knee arthroplasty (study group) were applied to a randomly selected side, and the total knee arthroplasty alone (as control group) was applied to the contralateral side of the same patient. The overall efficacy of both procedures was assessed postoperatively by determination of blood loss from the drain, pain and functional scores. The Visual Analogue Scale of pain and the Knee Society Knee Score were used to compare the two groups at 3rd, 6th and 12th months, postoperatively. During the postoperative 48 h, the mean blood loss in the study group (with synovectomy) was significantly higher than the control group (P = 0.005). However, in the postoperative follow-up time, there was no significant difference in pain relief and in the Knee Society Score between the two groups. Performing synovectomy in patients with primary knee osteoarthritis does not seem to have any clinical advantage besides it might increase blood loss and recurrent hemarthrosis postoperatively. Thus, during arthroplasty surgery, it should not be performed routinely.

Purpose A comparison was made of the clinical and radiological results of cylindrical fully porous-coated femoral stems (Group A) and Zweymüller-type femoral stems (Group B) used for the treatment of hip osteoathrosis, secondary to Crowe III and IV dysplasia, with total hip arthroplasty combined with femoral transverse shortening osteotomy. Method This study is a retrospective evaluation of 86 hips in 50 patients. Group A comprised of 43 hips and Group B comprised of 43 hips. During final follow-up evaluation, patients were clinically assessed with Harris Hip Score (HHS), Merle d'Aubigne-Postel scale (MAP), and SF-36 scale. For radiological examination the Gulman THA score was used. Femoral osteotomy union, osteolysis around the components and component migration were also recorded and evaluated. Results In Group B, nonunion of the osteotomy site was found in 18.6% and delayed union in 20.9% of the hips. In Group A, delayed union was found in 7% of the hips. Patients’ mean daily walking distance was found to be lower in Group A when compared to Group B. When the postoperative clinical HSS, and MAP and the radiological Gulman scores were compared, no statistically significant differences (p = 0.275) were found. Conclusions Patients with hip osteoarthritis secondary to Crowe III and IV dysplasia, who were treated with THA and transverse osteotomy showed a higher incidence of osteotomy complications when the Zweymüller femoral stem was used. However, these complications did not affect clinical outcomes.

Osteopoikilosis is a rare benign sclerotic bone dysplasia. The disease which usually develops asymptomatically is coincidentally diagnosed with direct radiographs. Our subject, a 52-year-old male was admitted to our policlinic two days ago due to turning of his left ankle causing pain and swelling on his left ankle. We asked for bilateral direct radiograph of left ankle. The left ankle radiograph indicates multiple, small oval/round hyperdense sclerotic regions. As a result of available clinical finding and radiological viewing, the patient was diagnosed with osteopoikilosis.

Lisfranc fracture dislocations cause severe tarso-metatarsal malalignment. The research question of this study was to evaluate the severity of the soft tissue injury on the final clinical outcome and compare that with the effect of various determinants on the disability in daily living activities after open reduction and internal fixation of a Lisfranc injury.This study consisted of a retrospective analysis of patients with Lisfranc fracture dislocations who were treated by open reduction and internal fixation beween 2004 and 2009. Evaluation focused mainly on the severity of the soft tissue injury, age, fracture classification, time to operation, posttraumatic osteoarthritis, and the results were compared with American Foot and Ankle Society (AOFAS) scores, and Foot and Ankle Disability Index (FADI). Eight patients had Tscherne Grade 1, 13 had Grade 2, and 11 had Grade 3 soft tissue injuries. Myerson classification revealed 11 type A, 8 type B and 13 type C fractures. Six patients' operations were delayed beyond 8h.Of the 38 patients treated in the study period, 32 patients (11 female, 21 male;30 y-old: 14,30 y-old: 18) were available for complete follow-up (average, 55.5 months). The comparison of treatment results revealed that those patients with high grade soft tissue injuries had lower AOFAS and FADI scores (43.8±15.9, 53.7±9.4, respectively) when compared to Tscherne Grade 1 injuries (82.8±6.1, 109±13.9, respectively) (p0.001). The overall negative impact of the severity of soft tissue injury on functional outcomes had similar significance with regard to post-traumatic osteoarthritis, and fracture type. There was also a statistically significant difference between outcome measures and post-reduction quality (p=0.002). Patient age (p=0.9) and delayed surgery (p=0.5) had no statistically significant effect on the final outcome.Satisfactory results can be achieved with open reduction for Lisfranc injuries. However, despite this treatment, both the severity of the soft tissue injury and non-anatomic reduction are negative prognostic factors in the treatment of Lisfranc fracture dislocations.

In this study we evaluated whether ligament transfer caused humeral head migration in patients whose massive rotator cuff ruptures were repaired with total or partial coracoacromial ligament (CAL) transfer. The necessity of harvesting the ligament totally or partially in massive rotator cuff repairs was investigated with respect to the effect of the excision and transfer of the CAL on humeral head migration.Forty patients (12 males, 28 females; mean age 54.3 years; range 39 to 66 years) operated on with free CAL transfer for massive rotator cuff rupture between January 2003 and June 2008 were included in the study. The operations were performed by obtaining total CAL grafts in the first 13 cases and partial CAL grafts in the other 27 cases. Mean follow-up period was 26.5 months (range 12 to 52 months). Twenty-nine patients had the rupture on the right side and 11 patients had the rupture on the left side. In 31 patients the dominant side was affected.In the early postoperative period (3-6 weeks) adequate acromiohumeral (AH) distance could not be obtained in patients underwent total excision and transfer of CAL (mean 9 mm; range 8.6 to 9.2 mm). Humeral migration was found to be regressed three months after active motion and recovery of normal cuff strength. During the follow-up the mean AH distance was found to be 10 mm (range 8 to 10.5 mm). Humeral head migration was not detected by ultrasonography in the early postoperative period in patients who underwent repair with partial CAL transfer.Functionally good results have been obtained in the rotatory cuff repairs performed by CAL excision and transfer. Although humeral head migration was not detected ultrasonographically in the patients who had partial CAL excision and transfer at the early postoperative period, we observed a decrease in the AH distance in the patients who had total CAL excision and transfer. This migration was regressed and the cuff strength was recovered after intense rehabilitation with strengthening exercises and active motion.

We evaluated the clinical and radiographic results of exclusively the same type and standard sized cementless total hip prostheses applied to all dysplastic and dislocated hips.In this study, we retrospectively reviewed 69 patients' (63 females, 6 males; mean age 45.6 years; range 20 to 72 years) 103 dysplastic or dislocated hips on which cementless total hip arthroplasty was performed between January 1998 and January 2006. The mean duration of follow-up was 7.2 years (range 2.0-10.1 years). Eighteen hips (17%) were type I, 29 hips (28%) were type II, 23 hips (22%) were type III and 33 hips (32%) were type IV according to the Crowe classification. Functional and clinical analyses were performed by Harris hip scores. At the last follow-up, the patients were asked whether they were satisfied or not after the operation.The average preoperative Harris hip score of 39.3 was progressed to 89.5 at the latest follow-ups (p0.001). Sixty patients (86.9%) reported that they were satisfied after surgery. We observed 41 (39.8%) complications in total, nine of which were intraoperative. There were no findings of symptomatic septic or aseptic loosening at the latest follow-ups.Cementless total hip arthroplasty is an effective procedure for developmental dysplastic and dislocated hips.

Total hip arthroplasty in dislocated developmental hip dysplasia is a complex, technically demanding procedure with high complication rates. Anatomic abnormalities and the young age of the patients influence the results. Restoration of the anatomic hip center often requires shortening of the femur in order to avoid over-stretching of neurovascular structures.We performed cementless total hip arthroplasty with subtrochanteric transverse osteotomy on 44 hips in 31 patients. There were 29 female and 2 male patients. The average age at the time of the operation was 43.2 (range, 22–63 years) and the mean follow up period was 62 months (range, 24–96 months). Harris hip scores improved from 36.2 to 81.2 with good and excellent results in 79.5% of the patients. We stabilized the osteotomy line with low contact plates and screws primarily on 10 hips when rotational stability was in doubt. In the other hips, good initial rotational stability was obtained by the femoral component. However, we observed 5 nonunions in patients whose osteotomies were not stabilized with plates. These patients were later treated succesfully with internal fixation and autogenous bone grafting. The osteotomies healed at a mean time of 4 months (range, 2.5–14 months).Postoperatively two dislocations, one acetabular component displacement under the structural bone autograft and two superficial infections were seen. There were no cases of symptomatic loosening, deep infection, or neurovascular injury.Subtrochanteric transverse osteotomy is a versatile, relatively easy and reliable method for shortening the femur when performing cementless total hip arthroplasty in hip dysplasia cases. This technique makes it possible to implant standard sized cementless femoral stems. When necessary, tortional stability may further be augmented with a plate and screws.
