A STUDY OF DISLOCATION AFTER PRIMARY TOTAL HIP REPLACEMENT BY POSTERIOR APPROACH
Dislocation after primary Total Hip Arthroplasty is devastating complication which may lead to neurovascular damage if not treated urgently. Posterior approach to hip is most commonly used worldwide. It said to have increased chances of dislocation postoperatively as compared to other approaches according to literature but still a debatable topic of discussion. In our study , we retrospectively studied 189 patients operated for primary THA in tertiary care centre fullling inclusion criteria. These patients were operated by same surgeon with posterior approach and uncemented implant with 28mm femoral head .Demographic data of patients and incidence of dislocation studied. Our observations and results found out that male patients are more common and are of young age group who undergone THA. Most common indication for surgery was Avascular necrosis of femoral head. Out of 189 , only 3 patients had episode of dislocation. With our study , we conclude that posterior approach to hip is safe if done by experienced surgeon with ideal implant positioning ,meticulous soft tissue repair & proper patient counseling for post-op rehabilitation
