Fracture mapping of proximal femoral lateral wall
Objective Using fracture map technology to study characteristics of the proximal femoral wall fracture, providing reference data for clinical and biomechanical studies. Method CT data from 96 patients with trochanteric fracture were collected. In the cases with proximal femoral lateral wall fracture, the lateral wall and fracture area (width, height, area, fracture line direction) were measured and fracture mapping was created. Result In 96 patients, 56 had lateral wall fractures. 71.4% were A2 type(40 cases). The average width of fractures area was (10.1±6.0) mm, the height was (23.1±11.3) mm, and the area was (158.5±105.2) mm2, accounting for (12.1±8.1)%. The fracture line was (64.6±14.5) ° with the horizontal plane. 28.6% were A3 type (16 cases). The average width of fracture area was (26.0±7.0) mm, height was (38.8±11.7) mm, and area was (860.1±357.0) mm2, accounting for (64.5±25.9)%. The angle of fracture line was (30.2± 39.6) °. Conclusion Characteristics of different types of trochanteric fractures of the lateral wall are significantly different. The fracture map can directly display fracture information. The results of this study can provide a reference for the standard fracture model in clinical and experimental study.
