Figure 8From: Massive heterotopic ossification associated with late deficits in posterior wall of acetabulum after failed acetabular fracture operation Intra-operative photograph. (a,b) The posterior acetabular wall defect was reconstructed with structured autograft harvested from the largest heterotopic ossific bone using an appropriate-sized acetabular reamer. (c) Then, the graft was placed in the deficiency. (d) Acetabular tridimensional memory alloy fixation system was used for internal fixation.Back to article page
