To synthesize evidence between tip apex distance
and screw cut-out after fixation of proximal femur
fractures by dynamic hip screw or intra medullary nail.
Methods: A retrospective cohort study of one hundred
and six patients from January 2021 till December 2021.
Patients who had fracture proximal femur managed using
a dynamic hip screw or intramedullary nail were included
in this study. A minimum of six months follow up in
mandatory for including patients as well. We excluded
patients who had fracture proximal femur managed by
Three patients complicated with screw cut-out, and
required conversion to hemiarthroplasty, while one
patient had a fall and experienced a fracture required
plate fixation. One patient converted to total hip
replacement due to non-union. The tip apex distance of
the failed patients were (32, 30, and 33) Two were fixed by
Dynamic hip screw (DHS) while one was fixed by
Proximal femoral nail (PFN).
Tip Apex Distance is a reliable indicator for
predicting screw cutting in intertrochanteric fractures
treated with Dynamic Hip Screw or Proximal femoral
