Delayed Osteonecrosis Following Reduction and Internal Fixation of a Femoral Neck Fracture
$25.00
Osteonecrosis (ON) is a common complication following femoral neck fracture and most studies have reported the incidence of ON after less than 3 years follow-up. Here we report a case of delayed osteonecrosis 7 years after initial treatment for a femoral neck fracture. This example supports the need for continued clinical and radiographic follow-up over an extended period after femoral neck fracture and suggests that 3 years is too short a time to reliably rule out ON as a postoperative complication.
