Background: The influence of varus insertion of femoral implants in uncemented total hip replacement arthroplasty (THR) remains unclear. Thus, in this study, we retrospectively assessed the clinical impact of uncemented THR with femoral implants that were inserted in varus on the basis of radiological findings.

Materials And Methods: The study participants included 89 patients who underwent uncemented THR for 106 joints and were followed-up for >3 years.

Introduction: We usually use short femoral nails for the treatment of trochanteric fracture of the femur. In this retrospective study, we investigated and compared the clinical results of the conventional intramedullary hip screw (IMHS) and the Asian IMHS, which is a redesigned version of the former.

Materials And Methods: The subjects were 42 patients; 21 treated with the Asian IMHS and 21 were treated with the conventional IMHS.
