Summary
Cemented total hip arthroplasty (THA) with subtrochanteric osteotomy for hip dysplasia is technically demanding. Outcomes were comparable to cementless techniques, despite a higher complication rate.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Hip Reconstruction
Background:
- Developmental dysplasia of the hip (DDH) presents unique challenges for total hip arthroplasty (THA).
- Femoral osteotomy may be necessary to restore hip joint anatomy.
- Cemented THA components are less studied in DDH compared to cementless options, particularly in osteopenic bone.
Purpose of the Study:
- To evaluate the union rate, complications, and functional outcomes of cemented THA combined with subtrochanteric osteotomy in DDH patients.
- To compare outcomes with existing literature on cementless THA in similar cases.
Main Methods:
- Retrospective review of 28 patients (35 hips) undergoing cemented THA for DDH with simultaneous subtrochanteric osteotomy.
- Minimum 2-year follow-up (mean 5.6 years).
- Assessment of union, complications, SF-12, and Oxford hip scores (OHS).
Main Results:
- 97% femoral union rate (32/33 femora).
- Overall revision rate of 20%; femoral revision rate of 9%.
- Improved SF-12 scores; decreased OHS; noted dislocations and transient neuropraxia.
Conclusions:
- Combined cemented THA and subtrochanteric osteotomy is technically challenging with a higher complication rate than standard THA.
- Outcomes regarding union, complications, implant survival, and early functional scores are comparable to cementless techniques.
