Femoral neck fractures in osteogenesis imperfecta patients: A retrospective case series and novel surgical technique

Abstract

Case: We conducted a retrospective review of three cases of femoral neck fractures treated operatively in patients with osteogenesis imperfecta (OI). All of our patients had acetabular protrusio as well as coxa vara deformity. All patients successfully underwent cannulated screw fixation without avascular necrosis (AVN). One patient required a sub-adductor hip arthrogram during a revision procedure to assist with visualization of the proximal femur which resulted in improved screw purchase.Conclusions: We report on three cases of femoral neck fractures in OI patients and a previously undescribed technique; using a hip arthrogram to assist in fluoroscopic evaluation of the proximal femur in these osteopenic patients.
