Vulvar Necrosis after Surgical Treatment of Femoral Neck Fracture: A Case Report and Investigation of the Mechanism of Injury

Abstract

We report the case of a young patient, presenting with total bilateral vulvar necrosis after reduction of a femoral neck fracture. This report describes the management of this complication, its mechanism of injury and the associated means of prevention. We present an investigation of the vulvar vasculature in order to understand the mechanism of injury. The study of the vulvar vasculature rejects the anatomical hypothesis of selective damage to the internal and external arteries. Instead, it suggests intraoperative impingement of the terminal blood vessels caused by compression against the perineal post prompting discussion on the use of moulded countertraction posts during orthopaedic surgery.
