Objective To assess long‐term follow‐up evaluations for the treatment of femoral intertrochanteric fractures with the “three‐finger method” assisted by proximal femoral nail antirotation (PFNA). Methods From January 2010 to January 2017, 123 patients were selected and followed for the treatment of femoral intertrochanteric fractures with PFNA assisted by the “three‐finger method” (application of the index finger, middle finger, and ring finger in the process of surgery to assist PFNA). There were 56 male patients and 67 female patients aged 52–93 years with an average age of 75.6 years, and 88 cases were due to a fall and 35 due to a traffic accident injury. The femoral necks were fixed with PFNA assisted by the “three‐finger method” applying the following procedure: traction reduction, determining the incision, inserting the needle, and placing screw. The Harris hip score, postoperative complications, hip pain and function status were statistically analyzed to evaluate the surgical efficacy and to discuss the surgical technique of the “three‐finger method” assisted by PFNA. Results According to the Harris scoring criteria, patients were followed for 1, 2, 4, 6, and 8 years, and the good outcomes of patients were recorded. The excellent and good rate of 87% was the highest in the second year of follow‐up. Then, the rate decreased following the eighth year of follow‐up. The excellent and good rate of 82.7% was the lowest. The patients with incisions healed well, there were no instances of fat liquefaction or infection. There were three cases of effusion, the rate was 2.4%. The secretions were cultured, and no bacterial growth was found. After treatment of the wound, it healed, and the spiral blade used for the femoral head did not wear out. There was one case of femoral head necrosis. There was no significant correlation between hip pain and sex and age (P > 0.05), and the function of the hip joint was significantly correlated with the age of the patients (P

Background The treatment for unstable intertrochanteric fractures in the elderly has always been a controversial issue. The aim in this study was to compare the curative effects of proximal femoral nail anti-rotation (PFNA) and cementless bipolar hemiarthroplasty (CPH) on femoral intertrochanteric fracture in the elderly. Methods From March 2008 to December 2012, 108 elderly patients with femoral intertrochanteric fractures were treated by PFNA or CPH. There were 63 males and 45 females, aged 75.3–99.1 years [(83.7 ± 5.6) years]. The patients’ bone mineral density was routinely measured, and the fractures were classified according to Evans-Jensen. The patients were divided into CPH group and PFNA group. The differences in operation time, intraoperative bleeding, immobilization duration, hospitalization time, Harris scores and postoperative complications including deep venous thrombosis, lung and urinary infection were analyzed. Results All patients were followed for 12.5–36.2 months [(28.0 ± 6.3) months)]. The operation time was (53.7 ± 15.2) min and (77.5 ± 16.8) min in PFNA group and CPH group, respectively (P P P P > 0.05); and the Harris scores after 1 year were (87.7 ± 7.9) points and (88.3 ± 9.2) points, respectively (P > 0.05). There was no significant difference in postoperative complications between the two groups (P > 0.05). Conclusion Both PFNA and CPH are safe and effective treatments for femoral intertrochanteric fracture in elderly patients. Nonetheless, CPH allows faster mobilization and recovery.

With the advent of global aging, the incidence, mortality, and medical costs of hip fracture among aged patients are increasing annually. The number of controlled clinical studies and health economics analyses that conform to evidence-based medicine principles is growing day by day. However, unfortunately, no specific recommendations regarding the procedures for the treatment of hip fracture are available. Meanwhile, the existence of both traditional treatment systems and new treatment theories means that most doctors confront difficult choices in their daily practice. These factors make the therapeutic approach for aged patients, especially among superaged patients with hip fracture, extremely challenging. This study focuses on superaged patients (> 80 years as defined by the World Health Organization) with hip fracture and includes their preoperative pathological condition; therapeutic decision-making in terms of the benefit and risk ratio, damage control theory, and enhanced recovery after surgery were also investigated. These patients were discussed specifically by combining the current treatment strategies from several experts and the results of a meta-analysis published recently. The study presents some new ideas and approaches currently recognized in the field, such as preoperative assessment, surgical planning, safety consideration, complication intervention, and enhanced recovery implementation, and further presents some clear interpretations regarding misunderstandings in clinical practice. Finally, optimized treatment according to damage control principles and enhanced recovery after surgery during the perioperative period among superaged hip fracture patients is defined.

Introduction: The ongoing outbreak of novel coronavirus disease 2019 (COVID-19) is a worldwide problem. Although diagnosing COVID-19 in fracture patients is important for selecting treatment, diagnosing early asymptomatic COVID-19 is difficult. We describe herein a rare case of femoral intertrochanteric fracture concomitant with early asymptomatic novel COVID-19. Case presentation: An 87-year-old Japanese woman was transferred to our emergency room with a right hip pain after she fell. She had no fever, fatigue, or respiratory symptoms on admission and within the 14 days before presenting to our hospital, and no specific shadow was detected in chest X-ray. However, chest computed tomography (CT) was performed considering COVID-19 pandemic, and showed ground-glass opacities with consolidation in the dorsal segment of the right lower lung field. Then, qualitative real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) was carried out and turned out to be positive. She was diagnosed right femoral intertrochanteric fracture with concomitant COVID-19 infection. Conservative treatment was applied to the fracture due to infection. After admission, fever and oxygen demand occurred but she recovered from COVID-19. Throughout the treatment period, no cross-infection from the patient was identified in our hospital. Conclusion: This case highlights the importance of considering chest CT as an effective screening method for infection on hospital admission in COVID-19-affected areas, especially in trauma patients with early asymptomatic novel COVID-19.

This study aimed to discuss the risk factors of perioperative blood transfusion after the application of proximal femoral nail antirotation (PFNA) in the treatment of elderly patients with femoral intertrochanteric fracture (FIF). Moreover, this study also aimed to analyze the causes of perioperative blood transfusion and provide guidance for clinical treatment. Records of elderly patients with FIF who were treated with PFNA in our hospital from September 2014 to May 2017 were reviewed. They were divided into transfused and nontransfused groups. The Student t test, Chi-squared test, and Fisher exact test were used in univariate analysis of 11 variables. Multivariate logistic regression analysis was performed to analyze the possible risk factors associated with postoperative blood transfusion after the application of PFNA in elderly patients with FIF. Correlations were sought using the Spearman rank correlation analysis. The univariate analysis showed that age, sex, type of fracture, admission hemoglobin (Hb), admission albumin, and intraoperative blood loss were significantly associated with perioperative blood transfusion (P = .000, .019, .000, .000, .000, and .007, respectively). The multivariate logistic regression analysis demonstrated that age (P = .019, odds ratio [OR] = 1.062), type of fracture (P = .001, OR = 4.486), and admission Hb (P = .000, OR = 0.883) were independent risk factors of postoperative blood transfusion. We found a significant positive correlation between perioperative blood transfusion and age (r = 0.264, P = .000) and type of fracture (r = 0.409, P = .000), but a negative correlation between perioperative blood transfusion and admission Hb (r = −0.641, P = .000). The main factors affecting perioperative blood transfusion are age, fracture type, and admission Hb. These results indicate that, in high-risk patients who are older in age, more unstable fractures, and lower admission Hb, monitoring Hb concentrations during the perioperative period is important to correct severe anemia in a timely manner and avoid exacerbating existing underlying diseases and inducing severe complications.

The aim of the present study was to investigate the application of 3D printing (3DP) rapid prototyping (RP) technique-assisted percutaneous fixation in the treatment of femoral intertrochanteric fracture (ITF) using proximal femoral nail anti-rotation (PFNA). A total of 39 patients with unstable ITF were included in the current study. Patients were divided into two groups: 19 patients were examined using computed tomography scanning and underwent PFNA with SDP-RP whereas the other 20 patients underwent conventional PFNA treatment. Anatomical data were converted from the Digital Imaging and Communications in Medicine format to the stereolithography format using M3D software. The 3DP-RP model was established using the fused deposition modeling technique and the length and diameter of the main screw blade was measured during the simulation. The postoperative femoral neck-shaft angle (NSA), surgery duration, intraoperative and postoperative blood loss, and the duration of hospital stay were recorded and compared with the corresponding values in conventional surgery. No significant differences were observed in mean PFNA size between the implants used and the preoperative planning estimates. It was demonstrated that the 3DP-RP assisted procedure resulted in more effective reduction of the NSA. Furthermore, patients undergoing 3DP-RP experienced a significant reduction in duration of surgery (P

The study aimed to investigate the effect of ratios of marrow cavity diameter to intramedullary nail diameter from different layers on hidden blood loss (HBL), overt blood loss (OBL) and total blood loss (TBL) during using proximal femoral nail antirotation-Asian version (PFNA)-II for femoral intertrochanteric fractures. We retrospectively studied 70 patients treated in our hospital recently. We recorded postoperative hematocrit (Hct) and OBL during operation. TBL and HBL were calculated using CROSS equation. The ratios of marrow cavity diameter to intramedullary nail diameter from different layers, including start of funnel, end of funnel and femoral isthmus, were measured. The mean of the ratio from frontal and lateral X-ray were designated as R. We classified all included participants into a high and a low matching group according to z-score of R within each layer. TBL, HBL, and OBL were compared between the 2 groups. We applied multiple linear regression analysis between the HBL as a dependent variable and gender, age, body mass index, fracture type, and R as independent variables. The present study indicated a significant reduction in the HBL and TBL in the high matching group compared to low matching group on three layers, whereas it showed no significant difference in OBL between the 2 groups on three layers. It showed that R values from start of funnel and end of funnel were significantly associated with HBL. Matching rate of PFNA II at the funnel might be an important factor for HBL and TBL postoperatively.

Curative effect of artificial femoral head replacement on hip joint function and complications of elderly patients with femoral intertrochanteric fracture were investigated. Eighty patients who were operated for femoral intertrochanteric fractures operation were randomly divided into observation group (n=40) and control group (n=40). The observation group was treated with artificial femoral head replacement, while the control group received internal proximal femur locking plate fixation. In the observation group, the operation time was shorter than that in the control group (P

Rationale: Anorexia nervosa is a chronic psychiatric disease defined by severe weight loss, due to fear of obesity, and self-imposed semi-starvation. Of the many complications following anorexia nervosa, low bone mineral density (BMD) is a significant risk factor for fractures. Anorexia nervosa is associated with higher risk of incident fracture in females across all age groups, and in males >40 years old. Sites at highest risk of fracture include the hip/femur and pelvis in females, and vertebrae in males with anorexia nervosa. Patient concerns: A 29-year-old woman known to have suffered from anorexia nervosa 15 years ago visited the emergency department due to right hip pain after falling while getting out of a taxi. During the period of anorexia nervosa, she had a body mass index (BMI) of 14.06 kg/m2 (weight, 36 kg; height, 1.60 m) and suffered from amenorrhea. At the time of presentation, she had a BMI of 19.53 kg/m2 (weight, 50 kg; height, 1.60 m) and had regular menstrual periods, indicating clinical recovery from anorexia nervosa. Diagnoses: Plain radiography, computed tomography, and bone scintigraphy revealed AO 31-A2.2 type right hip proximal femur intertrochanteric fracture. The BMD showed a T score of −3.9 in the hip and −3.6 at the lumbar level, indicating severe osteoporosis. Interventions: Osteosynthesis was performed with proximal femoral nail antirotation (PFNA) and wiring. Outcomes: There were no specific symptoms, such as trauma or infection, during postoperative rehabilitation and postoperative management, and she was discharged after 2 weeks. After 1 year of follow-up at our outpatient clinic, she had no complications. Lessons: Here, we describe an unusual case of unilateral femoral intertrochanteric fracture that occurred after clinical recovery from anorexia nervosa. This case indicated that the risk of fracture remains even after recovery of BMI. We propose that women who have clinically recovered from anorexia nervosa should be advised to undergo annual osteodensitometric analyses after consulting with specialists in other areas (psychiatry, endocrinology, eating disorders).

Background:The current study focuses on the comparison of postoperative muscular strength around the hip joint of patients with femoral intertrochanteric fractures treated either by cephalo-medullary (CM) nailing or a new bipolar hip prosthesis (BHP), an especially attached device to secure displaced greater trochanteric fragment.Methods:Twenty patients treated with CM nailing were age- and sex- matched with a control group of 20 patients treated with BHP. Maximum isometric forces at the bilateral hip joint were measured during the follow up period. Means of 3 measurements were represented.Results:The mean and standard deviation values (kg) of muscle strength at the non-operative/ operative side in the CM nailing group were as follows: flexion strength 9.5±4.7/8.5±4.9 (P=0.06), extension strength 6.2±3.5/5.5±3.7 (P=0.08), abduction strength at 0 degrees 7.7±3.5/6.2±2.8 (p=0.002), abduction strength at 10 degrees 5.5±2.0/4.2±2.0 (p=0.001). In the BHP group, mean and standard deviation values of muscle strength at the non-operative/ operative side were as follows: flexion strength 6.5±2.8/6.0±3.4 (P=0.08), extension strength 4.4±0.9/4.4±0.6 (P=0.83), abduction strength at 0 degrees 5.1±1.9/5.0±1.6 (p=0.12), and that at 10 degrees 4.7±1.4/4.6±1.3 (p=0.10).Conclusion:Our results demonstrate that CM nailing may cause a 25-30% decrease in postoperative muscle strength around the hip joint, particularly during hip abduction. With the new BHP, greater trochanter reduction is achieved allowing early weight bearing and maintaining strength in abduction. Surgeons should consider postoperative muscular strength as one of the necessary factors for selection of the appropriate surgical procedure.Level of Evidence:Therapeutic Level III.

BACKGROUND: Most surgeons do not fix the lesser trochanter when managing femoral intertrochanteric fractures with intramedullary nails. We have not found any published clinical studies on the relationship between the integrity of the lesser trochanter and surgical outcomes of intertrochanteric fractures treated with intramedullary nails. The purpose of this study was to evaluate the impact of the integrity of the lesser trochanter on the surgical outcome of intertrochanteric fractures. METHODS: A retrospective review of 85 patients aged more than 60 years with femoral intertrochanteric fractures from January 2010 to July 2012 was performed. The patients were allocated to two groups: those with (n = 37) and without (n = 48) preoperative integrity of the lesser trochanter. Relevant patient variables and medical comorbidities were collected. Medical comorbidities were evaluated according to the American Society of Anesthesiologists classification and medical records were also reviewed for age, sex, time from injury to operation, intraoperative blood loss, volume of transfusion, operative time, length of stay, time to fracture union, Harris Hip Score 1 year postoperatively, and incidence of postoperative complications. Postoperative complications included deep infection (beneath the fascia lata), congestive heart failure, pulmonary embolus, cerebrovascular accident, pneumonia, cardiac arrhythmia, urinary tract infection, wound hematoma, pressure sores, delirium, and deep venous thrombosis. Variables were statistically compared between the two groups, with statistical significance at P 0.05). The group with preoperative integrity of the lesser trochanter had significantly less blood loss (107.03 ± 49.21 mL) than those without it (133.96 ± 58.08 mL) (P < 0.05) and the operative time was significantly shorter in the former (0.77 ± 0.07 hours) than the latter (0.84 ± 0.11 hours) group (P < 0.05). CONCLUSIONS: The integrity of the lesser trochanter has no significant influence on the surgical outcome of intramedullary nail internal fixation of femoral intertrochanteric fractures.
