Abstract

Objectives. To determine, can femoral geometry and the degree of osteoporosis affect the probability of sustaining a pertrochanteric or femoral neck fracture.
Methods. Pelvic radiographs and medical records of 154 patients who had injured their hip and were admitted to the Hospital of Traumatology and Orthopedics during year 2017 were included in this study. They were devided into 3 groups based on the radiographic injury pattern – no fracture (Group 1) (n = 34), pertrochanteric fracture (Group 2) (n = 52) and femoral neck fracture (Group 3) (n = 68) groups. Patient age, gender, injury mechanism and radiological measurements including hip axis length, femoral neck axis length, femoral head diameter, femoral neck width, neck shaft angle,femoral shaft width, cortical thickness index (CTI) and Singh index (SI) were acquired using the Impax-OrthopaedicTools 3.0.2.3 program.
Results. The most common injury mechanism in all groups was falling on one side (97.4%). Women more commonly injured their hips than men (72.7% vs 27.3%) but this predominance was not statistically significant when compared between the 3 groups (p = 0.64). Comparing fracture group patients (Group 2 and 3) and patients with no fracture after trauma (Group 1), femoral shaft width (29.92 ± 3.15 vs 30.70 ± 1.83) and CTI was significantly lower (p = 0.04; p = 0.01) in Group 1, and there were
no patients with SI less than 4 (indicating osteoporosis) 0.0% vs. 38.3% (p = 0.001). Group 3 had significantly narrower femoral necks than Group 2 (p = 0.001), but Group 3 had significantly less patients with SI less than 4 (p = 0.001). All other quantitative and qualitative parameters did not differ between groups.
Conclusions. Proximal femoral geometry such as femoral shaft width, femoral neck width and specific signs of osteoporosis (SI, CTI) which are detectable in plain radiographs can be used to identify patients who are at the risk of fracture in the future. Decreased femoral neck width is a risk factor for femoral neck fractures.
