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 up a consecutive series of seven patients with femoral head fracture dislocation via a scope-assisted percutaneous headless screw fixation between 2016 and 2017. 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. None of the patients showed early osteoarthritis, heterotopic ossification, or avascular necrosis. The average maximal displacement of the fracture site was improved from preoperative 6.79 mm (range 4.21–12.32) to postoperative 2.76 mm (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.
