Staged Bilateral Total Hip Arthroplasty in a Patient With Larsen Syndrome

Larsen syndrome is a rare genetic disorder characterized by weak connective tissues and various musculoskeletal abnormalities. This is a case report of a 39-year-old patient with Larsen syndrome who presented with over a decade of bilateral hip pain and difficulty ambulating. This patient has a prior history of bilateral congenital hip dislocations that were treated with open reduction and spica casting as a child with good result. Years later, she went on to develop bilateral hip osteoarthritis with significant remodeling of the proximal femur. The goal of this case presentation is to demonstrate the utility of total hip arthroplasty for this patient and discuss surgical challenges and considerations.
