Summary
This study evaluated Müller cemented hip implants with femoral head autograft in developmental hip dysplasia patients, showing good functional outcomes and graft union despite some resorption.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Developmental hip dysplasia often requires surgical intervention, typically hip replacement.
- Long-term outcomes of cemented hip arthroplasty with bone grafting in this population are crucial.
Purpose of the Study:
- To assess the long-term efficacy and complications of Müller cemented hip arthroplasty with bulk femoral head autograft in patients with developmental hip dysplasia.
Main Methods:
- Retrospective review of 38 hip replacements in 33 female patients with developmental hip dysplasia.
- Utilized Müller cemented implants and bulk femoral head autograft in most cases.
- Reconstruction of the acetabulum at the true acetabular level was performed in 33 hips.
Main Results:
- Mean follow-up of 12.2 years (range 8-19 years) for 36 hips.
- Good functional scores achieved (pain 5.9, movement 5, walking 5.3).
- Complications included one femoral fracture, two dislocations, and one revision for aseptic loosening; all grafts united with varying degrees of resorption.
Conclusions:
- Müller cemented hip arthroplasty with femoral head autograft provides durable results for developmental hip dysplasia.
- While graft union is common, monitoring for resorption is necessary.
- The procedure effectively corrects leg length discrepancies and improves function.
