Abstract Objective: To evaluate the influence of hip osteoporotic fracture on geometric structure of the proximal femur, to study the influence of bone mineral density and its value in predicting hip osteoporotic fracture. Material and Methods: Two hundred and thirty-three cases examined by dual energy X-ray absorptiometry(DXA) were collected. There were 46 cases in the group of fresh hip osteoporotic fracture and 187 cases in the control group. Bone mineral density(BMD) and geometric structure of proximal femur(PFG) were measured for the uninjured hip of fracture group and the left hip of control group with Osteocore 3 DXA and senior orthopaedic special analysis tool, including femoral neck axis length(FNAL), femoral neck angle(FNA), medial offset(MO) and intertrochanter head(IH). Results: The FNAL, IH and MO in the hip fracture group were longer(P＜0.05) than those in the control group, but the FNA was smaller(P＜0.05). There were significantly difference between the two groups. Conclusions: The geometric structure difference of FNAL, FNA, MO, IH may add load to proximal femoral, which can increase the risk of hip fracture. Screening the osteoporotic patients with anomalous PFG and taking preventive measures and treatment are important to reduce the risk of hip fracture.
