Abstract

Case: A 92-year-old man with a cardiac pacemaker and a history of unilateral nephrectomy sustained a displaced femoral neck fracture. The patient underwent internal fixation surgery using three cannulated screws. 2 years later, he complained of lateral thigh pain. Radiography revealed obvious lateral protrusion of the screws, which was considered the cause of the pain. Reoperation was performed by exchanging the screw for shorter ones, resulting in an improvement of the thigh pain.
Conclusion: Although certain conditions must be met, highly invasive reoperation with prosthetic replacement can be avoided by using shorter screws after internal fixation failure.
