BACKGROUND: Conversion total hip arthroplasty (THA) is associated with higher rates of complications compared with primary THA, with prior surgical fixation of fractures in the ipsilateral hip shown to further increase these rates. There is a scarcity of literature on the effect of timing of conversion THA on complication rates. In this study, we evaluated early (≤6 months of index surgery) and late (>6 months of index surgery) conversion to THA following prior fixation of the proximal femur or acetabulum.
METHODS: Ninety-one patients who underwent conversion THA following prior surgical fixation of either the proximal femur or acetabulum were identified. Index surgery, fracture characteristics, time, and cause of failure were obtained. Postoperative complications evaluated following the conversion THA included infection, revision surgery rates, dislocation, and revision rates.
RESULTS: A total of 91 patients were included, of which 22 underwent early conversion to THA. In the early conversion group, 22.7% of patients had a complication versus 11.6% of patients in the late conversion group (P = 0.194). The most common complications were deep infection (18.2% vs. 5.8%), revision surgery (22.7% vs. 10.1%), and revision THA (18.2% vs. 5.8%). The early conversion group had a markedly higher rate of perioperative blood transfusion compared with the late cohort (P = 0.013).
CONCLUSION: In this study, we found a high rate of complications associated with early THA conversion. Patients should be counseled on the high risk for complications following early conversion to THA following failed fracture fixation.
