Comparison between single stage and two stage bilateral total hip replacement- our results and review of literature.

Bilateral total hip replacement (THR) is a common procedure nowdays. Staging of surgery is still a -matter of debate. We performed a study to compare single stage and two stage bilateral THR and discuss the peri-operative and post-operative advantages and complications. This was a retrospective study. 48 patients underwent single stage and 56 patients underwent two stage bilateral THR. The average follow up period was 64 months and 70 months respectively. The hospital stay was 5.6 days in single stage and 9.0 days in two stage bilateral THR. The total blood loss was 280 ml and 440 ml ; average blood trans-fusion was 1.6 units and 2.2 units and walk without support was started at 42 days and 58 days respectively. No difference in complication rate was seen. Single staged bilateral THR is a safe procedure. The definite benefits are short hospital stay, lower cost and early rehabilitation.
