Case: We present a 55-year-old woman with osteogenesis imperfecta (OI) who underwent total hip arthroplasty (THA). She developed aseptic loosening of the femoral stem and was revised to a longer stem necessitating 2 osteotomies because of the proximal femur varus deformity. This was complicated by implant subsidence. She ultimately required another revision adding a distal femur locking plate to augment construct stability.
Conclusion: The abnormal anatomy and suboptimal bone properties in patients with OI present unique challenges when performing THA. More aggressive prophylactic fixation to improve construct stability and prevent fracture may be necessary in this patient population.
