Abstract
Purpose: Femoral head fracture-dislocations are serious articular fractures that are associated with soft tissue injuries and are challenging to treat. Arthroscopic surgery may be a way to treat fracture reduction and fixation, thereby avoiding the need for extensive arthrotomy.
Methods: We followed a consecutive series of nine patients with femoral head fracture dislocation via a scope-assisted percutaneous headless screw fixation between 2016 and 2018. The clinical and radiological results were assessed.
Results: The locations of the fracture were all involving infra-foveal area. The mean follow-up duration was 18 (range 12-24) months. The mean Harris hip score was 90.8 (range 88-93) at the latest follow-up. No one showed early osteoarthritis (OA), heterotopic ossification (HO) or avascular necrosis (AVN). The average maximal displacement of fracture site was improved from preoperative 6.79mm (range 4.21-12.32) to postoperative 2.76mm (range 0.97-3.97). Concomitant intra-articular hip lesions secondary to traumatic hip dislocation can also be treated.
Conclusion: Managing the infra-foveal fracture of the femoral head using arthroscopic reduction and fixation with headless screws can be a safe and minimally invasive option. More patients and longer follow-up are needed for a definite conclusion.
