title: Mini-incision resurfacing arthroplasty of hip through the posterior approach.
abstract: The success of metal-on-metal hip resurfacing in the medium term in young and active patients is becoming evident. The procedure now can be done using a minimal approach developed by the senior author using a single posterior incision. This mini-incision resurfacing arthroplasty of the hip has made resurfacing more attractive to surgeons and patients. But does a mini incision approach allow reliable component placement? The results of 232 consecutive Birmingham Hip Resurfacings done using this approach between January and December 2004 are presented. Mean incision length was 11.8 cm. Seventy-seven percent of the incisions were between 9 and 12 cm long. Body mass index of the patients studied ranged from 17.6 to 46.7. Comparing the traditional approach with the mini-incision resurfacing arthroplasty of hip did not show a difference between the two groups in terms of operating time. The mean hospital stay was reduced by a day in the mini-incision group. The mean inclination of the acetabular components was within the target range in the two groups. Patient feedback shows that reduced postoperative pain, faster recovery rate, and better cosmesis make the mini-incision approach very popular. Although the mini incision is indeed appealing, it has a steep learning curve. In the early phase of the learning curve, care should be taken to avoid suboptimal component placement, which has the potential to affect long-term outcome adversely.
