Introduction

Dislocation is one of the most common orthopaedic complications after primary total hip replacement (THR). The reported dislocation rate in elective THR is 5–8%. This number increases up to 22% for THR done for neck of femur fractures. Due to the reported increase in dislocation for trauma, some surgeons prefer to do a hemi-arthroplasty or open reduction and internal fixation (ORIF). Hemi-arthroplasty is known to have poorer functional outcomes. Failure of ORIF is as high as 43%, and revision of failed ORIF to THR has reported dislocation rates of up to 42%.

Materials and methods

A retrospective review of all THR done for neck of femur fractures during 2006–2011 was undertaken. The patients in our institution who are considered for a THR must have an active life-style. Records were reviewed for delay to surgery, surgical approaches, articulations, bearing surfaces, follow up periods and cemented versus uncemented implants. We excluded all pathological fractures, extra-capsular fractures, failed ORIF, patients with incomplete data and patients with a follow-up period less than 3 months.

Hip dislocation was the end-point of the review and we did not study other causes of revision e.g. loosening of components or infection.
