Abstract:
Post-traumatic arthritis of the hip can develop in 12-57% of patients after an acetabular fracture. Once it develops, salvage treatment options include arthroplasty or arthrodesis. Delayed total hip arthroplasty (THA) has been shown to be a viable treatment option to decrease pain, improve stability and increase functional outcomes. Using cemented designs, earlier long-term studies reported satisfactory functional outcomes of delayed THA used to treat previously failed acetabular fractures. However, high aseptic loosening rates were also observed. Recent advances in cementless acetabular designs have shown comparable functional outcomes and loosening rates compared to those undergoing THA for non-traumatic arthritis. However, even with improvements in functional and radiographic outcomes, unique complications are commonly encountered in patients with previous acetabular fractures, including heterotopic bone around the hip, increased operative times and blood loss, aseptic loosening, sciatic nerve injury and dislocation. The outcomes and complications of delayed THA in patients with previous acetabular fracture will be reviewed.
