“…Based on anatomical form and location, hip fractures can be classified into cervical and trochanteric fractures. In recent decades, several studies have indicated that women with trochanteric fractures are older, thinner, shorter, and have less bone mass at the proximal femur. In the current study, we found that the average age of patients with trochanteric fractures was approximately 4 years older than that of patients with cervical fractures, and in female patients, those with trochanteric fractures were approximately 5 years older.…”

“…The OR for fractures decreased when the cross‐sectional area (CSA) and neck length of the femur increased 1.97 times and 1.73 times in femoral neck fractures, respectively, and the OR for fractures increased when the femoral neck width increased 1.53‐fold. In addition, the OR for fractures increased when the femoral neck width increased 1.45‐fold in trochanteric fractures. However, Li et al .…”

Objective To assess the differences in bone mineral density (BMD) and hip geometry in trochanteric and cervical hip fractures in elderly Chinese patients. Methods A consecutive series of 196 hip fracture patients aged over 50 years was recruited from November 2013 to October 2015, including 109 cases of cervical fractures (36 males and 73 females) and 87 cases of trochanteric fractures (34 males and 53 females). All patients were evaluated through dual‐energy X‐ray absorptiometry, and baseline characteristics, BMD and structural parameters were collected and reviewed. Results There were statistically significant differences in age, height, and body mass index between patients with each type of fracture, and patients with trochanteric fractures were older than those with cervical fractures, especially in women. The BMD in trochanteric fractures was markedly lower than in cervical fractures in all five sites of the hip by an approximate reduction of 10%, in both men and women. The cross‐sectional area, cross‐sectional moment of inertia, and the cortical thickness in the cervical fracture group were significantly higher than in the trochanteric fracture group. However, the buckling ratio of both the femoral neck and trochanteric region were significantly lower in the cervical fracture group. Age (/10 years), cross‐sectional moment of inertia in femoral neck and buckling ratio in trochanteric region were significant risk factors for trochanteric fractures compared with cervical fractures. Conclusions Compared with cervical hip fractures, patients with trochanteric fractures were older, had a lower BMD, and had less bone mechanical strength, especially in female patients. Age, femoral neck cross‐sectional moment of inertia (FNCSMI), and trochanteric region buckling ratio (ITBR) were stronger risk factors for trochanteric hip fractures than for cervical fractures.

“…Owing to the high rate of morbidity and mortality in hip fractures, it is necessary to predict the occurrence of hip fractures accurately. Various studies have demonstrated that the proximal femur geometry was associated with the occurrence of hip fractures in elderly patients [12,18]. Similar to previous studies [10,13], a larger neck shaft angle and a longer femoral neck length were found to be independent predictors for hip fractures in both sexes.…”

“…Furthermore, several studies revealed that the simple measurement of the proximal femur geometry could predict the occurrence of hip fractures independently of BMD [9,10]. At present, the proximal femur geometry had been extensively investigated to predict the occurrence of hip fractures in elderly patients [11][12][13].…”

Introduction: Owing to the diverse design, measurement methods and ethnic differences, the influence of the proximal femur geometry on hip fractures is still unclear. Therefore, this study aimed to investigate morphological characteristics of the proximal femur in senile patients with hip fractures on three-dimensional images. Material and methods: One hundred and sixteen women and 38 men with hip fractures were included in the fracture group. The control group included 74 women and 63 men. The geometrical parameters of the proximal femur were measured after three-dimensional reconstruction. The femoral neck width (FNW), femoral neck length (FNL), femoral head height (FHH), femoral head diameter (FHD), neck shaft angle (NSA) and offset were measured and statistically analyzed. Results: The NSA in fracture cases was significantly larger than controls in both men and women (130.18 vs. 126.93, p = 0.001; 131.07 vs. 128.68, p < 0.001, respectively). Moreover, a lower total hip bone mineral density (BMD) in fracture cases was found in both sexes (0.725 vs. 0.812, p = 0.001; 0.743 vs. 0.830, p < 0.001, respectively). In multiple logistic regression analysis, a larger NSA and a lower total hip BMD were independent predictors for hip fractures in both men and women (OR = 1.143 and 1.171, p = 0.010 and 0.016, respectively). However, the FNL was an independent predictor for hip fractures only for women (OR = 1.201, 95% CI: 1.106-1.305, p < 0.001). Conclusions: A larger NSA and a lower BMD were independent predictors for hip fractures of senile patients in both sexes. Moreover, a longer FNL was an independent risk factor for patients with hip fractures in women. As a result, we hypothesized that the geometrical measurement of the proximal femur on three-dimensional images might be appropriate.

“…Intertrochanteric fractures account for nearly half of all hip fractures. Coinciding with the aging of the population, the incidence of osteoporosis in the elderly has increased, and the incidence of intertrochanteric fractures has increased year by year. The treatment of intertrochanteric fractures of the femur can be divided into conservative treatment and surgical treatment.…”

Objective To compare the clinical efficacy of intramedullary nail fixation for intertrochanteric fractures assisted by orthopaedic robot navigation and the traditional intramedullary nail fixation in elderly patients, and to investigate the application advantages of intramedullary nail fixation for femoral intertrochanteric fractures assisted by orthopaedic robot navigation in the elderly. Methods Among the 51 patients with intertrochanteric fractures who were selected from April 2015 to September 2017 in the Affiliated Hospital of Chengdu University, 25 patients underwent the intramedullary nail fixation assisted by orthopaedic robot navigation (orthopaedic robot navigation surgery group) and 26 patients underwent the traditional intramedullary nail fixation (traditional surgery group). The operation time, the number of intraoperative fluoroscopy images taken, the frequency of guide pins inserted into the femoral marrow cavity, the amount of intraoperative bleeding, and the one‐time success rate of the guide pin inserted into the femoral marrow cavity were recorded. Fracture healing and internal fixation were observed. The Harris score was used to evaluate hip joint function 1 year after surgery. Results All patients were followed up for 12–24 months. The operation time was 65.44 ± 8.01 min in the orthopaedic robot navigation surgery group and 77.50 ± 16.64 min in the traditional surgery group. The number of intraoperative fluoroscopy images taken was 10.28 ± 0.61 in the orthopaedic robot navigation surgery group and 13.23 ± 1.75 in the traditional surgery group. The frequency of guide pins inserted into the femoral marrow cavity was 1.00 ± 0.00 times in the orthopaedic robot navigation surgery group and 2.46 ± 1.10 times in the traditional surgery group. The one‐time success rate of intramedullary pin puncture was 100% (25/25) in the orthopaedic surgical robot navigation surgery group and 19.23% (5/26) in the traditional surgery group. The amount of surgical bleeding was 90.80 ± 14.98 mL in the orthopaedic robot navigation surgery group and 118.46 ± 32.21 mL in the traditional surgery group. Compared with the traditional surgery group, the operation time of the orthopaedic surgical robot navigation surgery group was shorter (P < 0.05), the number of intraoperative fluoroscopy images taken was fewer (P < 0.05), the frequency of guide pins inserted into the femoral marrow cavity was lower (P < 0.05), the one‐time success rate of intramedullary pin puncture was higher (P < 0.05), and the amount of surgical bleeding was less (P < 0.05). One year after surgery, fracture healing occurred in both groups without failure of internal fixation or fracture displacement. The Harris score of hip function in the orthopaedic robot navigation surgery group was 86.68 ± 6.23 and that in the traditional surgery group was 82.69 ± 6.85. It was higher than that in the traditional surgery group (P < 0.05). The fine rate of hip joint function in the orthopaedic robot navigation surgery group was 84.00% (21/25) and that in the tradition...
