Abstract
BackgroundNonunion after periprosthetic femoral fracture is a recalcitrant challenge for hip surgeons. Case presentationA 55-year-old man underwent hemiarthroplasty for right femoral head osteonecrosis at another hospital. Two weeks after surgery, he developed a periprosthetic femoral fracture. He was referred to our hospital because of nonunion of the fracture site even after five surgeries. Surgery was performed using a cementless long stem combined with a locking plate. Three locking screws were passed through the distal holes of the stem to improve fixation. Bone union was achieved, and he was able to walk six months after surgery. ConclusionsA cementless long stem with interlocking screws inserted via a locking plate offers rigid stability and bone union. Our report is relevant because it highlights a surgical option for recalcitrant nonunion after periprosthetic femoral fractures.
