Summary
Hip revision surgery for patulous proximal femurs can utilize reduction osteotomies or ingrowth sleeves. Both methods show good outcomes, with a low overall rerevision rate of 1.7% in patients with expanded femurs.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Hip Arthroplasty
Background:
- Patulous proximal femurs present a surgical challenge in hip revision.
- Traditional methods may be insufficient for managing expanded femoral canals.
Purpose of the Study:
- To evaluate the efficacy of reduction osteotomies and large ingrowth sleeves for hip revision in patients with patulous proximal femurs.
- To compare the long-term outcomes of these two surgical techniques.
Main Methods:
- A retrospective review of 309 patients undergoing hip revision surgery for patulous proximal femurs.
- Surgical interventions included reduction osteotomies (n=6) and large ingrowth sleeves with proximally modular stems.
- Follow-up duration averaged 8.6 years.
Main Results:
- Reduction osteotomies in six patients yielded successful outcomes.
- The overall rerevision rate for both techniques was 1.7%.
- Both methods demonstrated acceptable long-term results.
Conclusions:
- Reduction osteotomies and large ingrowth sleeves are effective treatment options for hip revision in patients with patulous proximal femurs.
- These techniques offer favorable outcomes and low rerevision rates, suggesting suitability for managing expanded femoral canals.
