Summary
Revision hip surgery often involves acetabular bone stock deficiency. This study details a technique using morcellized bone graft and reconstruction rings, achieving stable acetabular components and bone stock restoration in most patients.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Bone Grafting Techniques
Background:
- Acetabular bone stock deficiency is a significant challenge in revision hip arthroplasty.
- Restoring bone stock and achieving a stable acetabular construct are critical for successful outcomes.
Purpose of the Study:
- To describe a surgical technique for managing complex acetabular deficiencies using particulate allograft and reconstruction rings.
- To evaluate the clinical and radiological outcomes of this technique in revision hip surgery.
Main Methods:
- Morcellized bone graft was used to reconstruct the acetabular floor in large defects.
- A metallic reconstruction ring was fixed with screws, compressing the graft.
- A cemented polyethylene acetabular component was implanted into the reconstructed acetabulum.
Main Results:
- The technique was applied to 48 patients with a mean follow-up of 64 months.
- Good bony incorporation and stable acetabular components were observed in 46 out of 48 cases.
- Two cases were complicated by sepsis, impacting the outcome.
Conclusions:
- This technique effectively restores acetabular bone stock and provides stable fixation for acetabular components in revision hip surgery.
- The use of morcellized allograft with reconstruction rings is a viable option for complex acetabular deficiencies.
