Does the angle between dynamic hip screw and anti-rotation screw affect the outcome of vertically oriented femoral neck fractures? A biomechanical analysis and clinical results

Femoral neck fracture (FNF) is a commonly encountered injury in the orthopedic practice, in which the vertically oriented femoral neck fracture (VOFNF) is the most unstable one [1]. The postoperative complications corresponding nonunion of the fracture and osteonecrosis  of the femoral head are hard to be overcome, which increases the difficulty of the treatment [2]. Despite the improvement of surgical techniques, the failure rate of the VOFNFs is still relatively high, with a nonunion rate of 20-27% and an incidence of osteonecrosis of 10-11% [3].
