Brief summary

There has been a recent drive to perform hip replacements through smaller incisions. The question is, does this increase the risk of complications? The primary purpose was to assess whether a hip replaced through a smaller incision produced as good a result as when done through a standard incision. Our hypothesis was that it did, and was possibly more beneficial since fewer tissues were divided.

Interventions

Single-incision mini-posterior approach to the hip. This technique involves a smaller incision (around 10cm) and sparing of some short external rotators (namely Piriformis) than a standard approach. Each approach takes the same time (around 60-90 minutes)
