Abstract

Introduction: Total hip arthroplasty by posterior approach preserving piriformis has been shown to be an effective, safe and minimal invasive surgery which has faster recovery and reduces complication and dislocation rate. Material and Methods: Patients were recruited from January 2024 to June 2024 and were followed up for a minimum of 12 months (until June 2025). Outcome measures included intraoperative parameters, early recovery indicators, and the Harris Hip Score (HHS). Results: Mean surgical time was 70,2 ± 13,0 minutes, mean incision length was 8,45 ± 1,3 cm, mean blood loss was 222,6±22,2 ml with decrease of Hgb post operation was 1,60 ± 0,89 g/dL, no blood transfusion case. Harris hip score pre -operative,3 months, 6 months and 12 months post-operative are 44 ± 4,25, 84,8 ± 2,1; 90,6 ± 2,1; 93,8 ± 2,1, 01 case had piriformis release intra-operative (3,12%). Conclusion: Total hip arthroplasty with piriformis-sparing posterior approach has been shown to be a safe and effective surgical approach with fast recovery, lower blood loss, lower complication and dislocation rate. This approach can be feasible performed with normal surgical table and suitable with variable prothesis designs without special instruments needed.
