Abstract
BackgroundAcetabular reconstruction with bone impaction grafting in large defects has yielded conflicting results.MethodsThis was a retrospective study of a case series of five patients with a young age (≤50 years) at the time of surgery who had large acetabular defects reconstructed by bone impaction grafting and trabecular metal augments. The mean follow-up was 79 months. We describe the surgical technique in detail.ResultsImprovement was significant on the WOMAC and SF-36 scales (p < 0.05). The radiographs taken at the last follow-up examination showed no migration of the polyethylene cup (p = 0.31) or differences in the abduction angle (p = 0.27) compared to the radiographs from the immediate postoperative period. One patient presented two dislocation episodes as a complication.ConclusionThe combination of trabecular metal augments with the bone impaction grafting technique in young patients with large acetabular defects provides satisfactory results in the long term and restores the bone stock.
Highlights
Acetabular reconstruction with bone impaction grafting in large defects has yielded conflicting results
We have proposed using trabecular metal (TM) augments in combination with bone impaction grafting to aid in the reconstruction of large bone defects
Patients and methods The study identified a consecutive series of patients who underwent acetabular revision using trabecular metal augments and the bone impaction grafting technique during the period from May 2011 to May 2014
Summary
Acetabular reconstruction with bone impaction grafting in large defects has yielded conflicting results. Methods: This was a retrospective study of a case series of five patients with a young age (≤50 years) at the time of surgery who had large acetabular defects reconstructed by bone impaction grafting and trabecular metal augments. Acetabular revision surgery for large defects is a challenge for orthopaedic surgeons. This challenge is greater when these defects occur in young patients, in whom it is essential to restore the centre of rotation of the hip, achieve stable implant fixation, and restore the acetabular integrity and the bone remnant. Several treatment options have been described to achieve this end, with different results [1,2,3,4,5,6]. The only option that can restore bone remnant is bone allograft
