Abstract
The goal of converting a hip fusion to a total hip arthroplasty (THA) is to improve mobility and function by replacing the fused joint with a more flexible and functional prosthetic implant. This complex procedure addresses challenges related to altered biomechanics and potential bone loss from the previous fusion. In this case report, we discuss the conversion of a post-traumatic hip fusion to THA in a 25-year-old female with debilitating pain and function impairment to movement. Clinical and plain radiographic findings are discussed. This report highlights the necessity of comprehensive preoperative assessments and individualized surgical strategies to optimize surgical outcomes in patients with prior hip fusions to improve their mobility, pain relief, and overall satisfaction.
