“…Overall, the patients in the CFP group experienced seven intraoperative fractures of the lateral femoral diaphysis at the tip of the stem and six of these involved an exaggerated neck-shaft angle. The CFP prosthesis is designed in accordance with the normal anatomy of the femur, with two neck-shaft angles (126° and 117°); Jiang et al [ 19 ] reported that the mean neck-shaft angle in a Chinese Han population was 133°. They also showed that adults younger than 60 years had a significantly higher neck-shaft angle.…”

BackgroundThis retrospective study investigated the relative benefits of using a collum femoris-preserving prosthesis or ribbed stem during total hip arthroplasty (THA).MethodsThe clinical results were compared of patients who underwent THA, between January 2010 and December 2012, with either a CFP prosthesis or a ribbed stem (66 and 75 patients, respectively, aged 43.4 ± 10.8 and 42.3 ± 9.8 years). Patients were assessed using the Harris Hip Score (HHS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), 12-Item Short Form Health Survey (SF-12), and physical component summary (PCS) score. Intraoperative and postoperative complications and leg-length differences were noted.ResultsThe mean follow-up times of the CFP and ribbed groups were 67.2 ± 7.5 and 68.3 ± 7.2 months, respectively. The HHS, SF-12 MCS, SF-12 PCS, and WOMAC scores of the two groups were similar. The rates of periprosthetic femoral fractures and leg-length differences > 10 mm in the CFP group (10.6% and 13.6%, respectively) were significantly higher than those in the ribbed group (1.3% and 2.7%). The groups were similar regarding complications of osteolysis, ectopic ossification, dislocation, deep infection, deep venous thrombosis, thigh pain, and aseptic loosening. The survival rates of the CFP and ribbed groups were comparable (98.5% and 97.8%).ConclusionThe clinical results of the CFP and ribbed prostheses in young patients given THA were similar for Chinese patients. However, the CFP stem should be used with caution, given the high incidence of technical problems associated with implantation especially for Chinese patients.

“…Current prosthesis selection in Chinese clinical practice is based on the results of foreign studies, such as the Nobel index of femoral medullary morphology. [ 16 ] Many other studies have focused on the morphology of hips in Caucasians, but corresponding studies in Asian populations are limited, particularly data on proximal femoral geometric parameters in Han Chinese. [ 16 ] Our study analyzed the geometric parameters of the hip in 198 patients with hip fractures compared to different types of hip fractures.…”

Background:Few studies have investigated the differences in proximal femoral geometry and risk factors between patients with different types of hip fracture, especially in elderly Chinese. This study aimed to assess the differences in proximal femoral geometry parameters between patients with femoral neck fractures and patients with intertrochanteric fractures to provide guidance for individualized customized prosthesis and accurate reconstruction of proximal femurs in elderly Chinese patients.Methods:We retrospectively studied the electronic medical records of 198 elderly patients over 65 years of age who were admitted to the orthopedic department with hip fractures between January 2017 and December 2017 in The Third Hospital, Hebei Medical University. Age, fracture site, gender, and proximal femoral geometry parameters (neck shaft angle [NSA], center edge angle [CEA], femoral head diameter [FHD], femoral neck diameter [FND], femoral neck axial length [FNAL], hip axial length [HAL], and femoral shaft diameter [FSD]) were recorded. Student's t-test was used to compare the continuous variables, Chi-square test was used to analyze categorical variables, and multiple logistic stepwise regression analysis was used to evaluate the influencing factors of hip fracture type.Results:Statistically significant differences in NSA (137.63 ± 4.56° vs. 132.07 ± 4.17°, t = 1.598, P < 0.001), CEA (37.62 ± 6.77° vs. 43.11 ± 7.09°, t = 5.597, P < 0.001), FND (35.21 ± 3.25 mm vs. 34.09 ± 3.82 mm, t = 2.233, P = 0.027), and FNAL (99.30 ± 7.91 mm vs. 103.58 ± 8.39 mm, t = 3.715, P < 0.001) were found between the femoral neck fracture group and femoral intertrochanteric fracture group. FHD, FND, FSD, HAL, and FNAL were different between sexes (all P < 0.001). The greater NSA was the risk factor for femoral neck fractures (odds ratio [OR]: 0.70, P < 0.001), greater CEA and longer FNAL were risk factors for femoral intertrochanteric fractures (OR: 1.15, 1.17, all P < 0.001), and greater FND was a protective factor for femoral intertrochanteric fractures (OR: 0.74, P < 0.001).Conclusions:We demonstrate differences in geometric morphological parameters of the proximal femur in different hip fracture types, as well as an effect of sex. These differences should be considered in the selection of prostheses for fracture internal fixation and hip replacements. These data could help guide the design of individualized customized prostheses and improve the accurate reconstruction of the proximal femur for elderly Chinese hip fracture patients.

Background. The present study evaluated some anatomical characteristics of the acetabulum and proximal femur in the hips of adult asymptomatic Vietnamese individuals. Methods. We used 32 slice computed tomographic system with a multiplanar reconstruction (MPR CT) protocol to evaluate several parameters of the acetabulum and proximal femur, including Acetabular diameter (ADi), Acetabular depth (ADe), Acetabular ratio (AR, calculated by (ADe/ADi) x100), Acetabular inclination angle (AI), Acetabular anteversion angle (AA), Centre-edge angle (CE), Femoral head diameter (FDi), Femoral neck anteversion (FA), Combine anteversion angle (CA, calculated by AA + FA), Femoral shaft-neck angle (SN), and Femoral medial offset (FO). Results. The average of parameters of ADi,
