  • 简介:AbstractIntracapsular fractures of the proximal femur are one of the most common fractures of the lower limbs. Most cases require osteosynthesis with suitable implants, and intraoperative positioning of the patient on the fracture table is a prerequisite to facilitate fracture manipulation, traction, reduction and fluoroscopy assessment. However, positioning the limbs of bilateral above-knee amputees for internal fixation of related proximal femoral fractures is a difficult task, which requires customized inventory for effective limb positioning and fracture manipulation. This study reported a rare case following a crush injury of bilateral lower limb in a road traffic accident, and described some technical tips of acute femoral neck fractures in bilateral above-knee amputation. The patient was managed with immediate guillotine amputation and later secondary wound closure followed by internal fixation of the right-sided femoral neck fracture with multiple cancellous cannulated screws.
