Summary: Despite higher BMD and lower TBS values in T2DM patients compared to controls, LS-TBS, LS-BMD, and femoral neck BMD showed acceptable discriminative ability in distinguishing between T2DM patients and controls in the total population and in women.

Summary: This study aims to determine the association of lean mass and fat mass with bone mineral density in Thais. The results show that in men, lean mass index is positively correlated with lumbar spine and femoral neck bone density, while fat mass index is negatively correlated with femoral neck bone density. In women, both lean mass and fat mass index are positively correlated with lumbar spine and femoral neck bone density. These findings indicate a sex-specific influence of fat mass on bone density in Thais.

Summary: Exercise induces spatially heterogeneous bone changes in the proximal femur, with 3D-DXA technology able to assess these changes. However, there were significant differences in bone strength under different loading configurations before and after exercise intervention. The study suggests caution when interpreting the results of 3D-DXA technology in individual cases.

Summary: The study compared the efficacy and side effects of PENG block with femoral block in postoperative pain control after hip fracture surgery. While there was no significant difference in postoperative morphine consumption, pain intensity, time to ambulation, incidence of morphine-related side effects, or length of hospital stay between the two groups, the PENG block did result in significantly improved postoperative muscle strength of the quadriceps.

Summary: The mortality rate is high after hip fractures, but the 1-year mortality rate differs between intertrochanteric fractures and femoral neck fractures. Older age and high Charlson comorbidity index score are risk factors for intertrochanteric fractures, while treatment with zoledronic acid can improve survival rate. In femoral neck fracture patients, physicians should pay careful attention to male patients, older patients, and those with high numbers of comorbidities.

Summary: Anticoagulation use in the elderly for femoral neck hip surgery presents a challenge in balancing comorbidities and patient benefits. This study compared the outcomes of patients using warfarin and therapeutic enoxaparin preoperatively. Results showed that warfarin use was associated with longer hospitalization days and delays to theatre, but did not affect postoperative outcomes.

Summary: Regular exercise, especially high-intensity physical activity, can help slow down age-related bone loss and prevent a decline in femoral neck bone mineral density.

Summary: The association between vegetarian diets and bone mineral density (BMD) Z-scores at various skeletal sites was examined. Current vegetarians, especially vegans, lacto-vegetarians, and lacto-ovo-vegetarians, had significantly lower BMD Z-scores compared to non-vegetarians. Sole reliance on a vegetarian diet might have a negative impact on bone health.

Summary: This study compared the clinical efficacy and outcomes of FNS and CCS in the treatment of femoral neck fractures in adults below 65 years old. The results showed that the FNS group had significantly shorter fracture healing time, fewer fluoroscopies, higher Harris Hip Score, and lower postoperative complications, with no significant differences in other factors.

Summary: This study aimed to investigate the effects of postoperative femoral neck shortening in patients with femoral neck fractures fixed with femoral neck system screws (FNS) and to explore the influencing factors. The data of 113 patients with femoral neck fractures were retrospectively analyzed, and the incidence of femoral neck shortening, postoperative complication rates, and hip Harris scores were compared between the femoral neck shortening group and the femoral neck no shortening group. The results showed that FNS fixation of femoral neck fractures had a high incidence of postoperative neck shortening, and factors such as cortical comminution, fracture type, and fracture reduction quality were significantly correlated with neck shortening. Femoral neck shortening can affect postoperative hip function but does not affect fracture healing.

Summary: This study compared the fixation stability and mechanical characteristics of basicervical femoral neck fractures fixed using FNS and DHS, showing no significant differences and suggesting that FNS fixation may provide biomechanical stability comparable to DHS for treating such fractures in young adults.

Summary: Using national representative data, this study found differences in the prevalence of low bone mineral density and associated risk factors among different race and ethnic groups. Advanced age, female gender, and fracture history were consistently associated with increased odds of low BMD across all race/ethnic groups, while other factors varied by race/ethnicity. The association between sleep duration and low BMD was modified by age and sex.

Summary: This case series highlights peri-implant subtrochanteric femur fractures as an unreported complication associated with the use of FNS for femoral neck fractures. These fractures were observed exclusively in patients with incomplete nondisplaced fractures who received FNS fixation. No similar complications were observed in patients treated with other types of fixation. This finding suggests the need for caution and further investigation when considering FNS as a treatment option for this specific fracture pattern.

Summary: Osteonecrosis of the femoral head, particularly involving the lateral head-neck junction, was confirmed as a major risk factor for spontaneous femoral neck fractures (SFF). The study also found that steroid use and osteoporosis were significant risk factors for SFF. Different causes of SFF were associated with different fracture types. MRI and pathological examinations showed that osteonecrosis in the SFF group predominantly occurred at the lateral head-neck junction.

Summary: The study conducted biomechanical tests and clinical retrospective analysis on femoral neck fractures. Results showed that the 3CCS + mFNSS group had better torsion resistance compared to the 3CCS group, but inferior compressive strength and fatigue resistance compared to the DHS group. In clinical application, the 3CCS + mFNSS group had lower screw retreatment and femoral head necrosis rates, and better fracture healing rates than the 3CCS group, indicating the effectiveness of medial support screws in promoting fracture stability and healing.
