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: 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: This case report describes a male patient with ankylosing spondylitis (AS) who developed bilateral subchondral insufficiency fractures (SIF) of the femoral head, which has not been reported in AS patients before, and the association between AS and SIF has not been established.

Summary: Subchondral insufficiency fracture (SIF) of the femoral head is a major cause of rapidly progressive osteoarthritis of the hip (RPOH). It is a rare disease most commonly found in elderly women with osteoporosis, often misdiagnosed as femoral head osteonecrosis. Early radiological detection of SIF is challenging, but characteristic manifestations can be seen on MRI. Severe cases may require total hip arthroplasty.

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: This study aimed to determine the incidence and risk factors for subchondral insufficiency fracture (SIF) of the femoral head following renal transplantation (RT). The analysis of 681 RT patients revealed that osteoporosis, lumbar bone mineral density (BMD), serum phosphorus (P), and serum calcium-phosphorus product (Ca x P) were identified as risk factors for SIF. These factors should be evaluated before RT for the prediction of SIF risk.

Summary: This study aimed to identify perioperative risk factors and clinical outcomes of postoperative delirium in patients undergoing hip bipolar hemiarthroplasty for displaced femoral neck fractures. Risk factors for postoperative delirium included a Charlson Comorbidity Index (CCI) score >= 6, nighttime surgery, surgical delays, preoperative anemia, and blood transfusions. Delirium was associated with sepsis, longer hospital stays, higher 1-year mortality, and overall mortality. Early identification of high-risk patients and optimization of medical conditions before and after surgery are crucial.

Summary: After observing a high rate of FHC following hip IACSI, a systematic evaluation was conducted with process improvement to improve patient/provider awareness and develop practice guidelines. Quality improvement interventions led to decreased treatment referrals, reduced repeat injections per patient, and a 5% lower FHC rate. Variation in practice patterns persisted, leading to the establishment of a systems-based Clinical Pathway.

Summary: This study analyzed the characteristics of individuals with subsequent contralateral proximal femoral fracture (PFF) following surgical therapy for first PFF and investigated whether these patients received examination or treatment for osteoporosis, as well as explored the reasons for lack of examination or treatment.

Summary: The optimal position of three cannulated screws for internal fixation of femoral neck fractures was determined using CT images processed with MIMICS software. Finite element analysis showed that this fixation scheme provides stronger fracture support and stability. In a clinical study, the modified screw placement method demonstrated larger stabilization screws with a shorter apex-subchondral bone distance compared to the conventional method. All fractures healed within a follow-up period of 10 months, with no incidence of screw penetration.

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: A new measurement method was designed to assess the injury degree of the femoral head in patients with FHFs and investigate its association with FNFs. The 2D and 3D parameters were found to be feasible adjunctive diagnostic tools in identifying FNFs.

Summary: The study aimed to investigate the effects of imaging position and sex on NSA measurement and provide reference values. The findings showed no significant difference in NSA between the right and left in standing radiographs, but significant asymmetry was found in supine radiographs. Further research is needed to confirm these results.

Summary: Pediatric femoral shaft combined with ipsilateral femoral neck fractures are rare but challenging injuries. In this study, minimally invasive procedures utilizing cannulated screws combined with elastic stable intramedullary nails showed good follow-up results in two cases.
