(A) A 65‐year‐old male underwent THA with a ribbed stem because of hip dysplasia and was found to have sustained an IPFF at the distal side of the right femur the day after surgery. No reoperation was performed because the fracture was regarded as stable. The patient was asked to delay weight‐bearing and received intensive care. The fracture was found to be healed at a subsequent follow‐up. (B) A 62‐year‐old male underwent one‐stage bilateral THA with a Corail stem because of hip fusion resulting from ankylosing spondylitis. Postoperative AP radiograph showed that the femoral stems did not match the medullary cavities and that a fracture of the distal femur was present on the right side, which had not been detected intraoperatively. The fracture healed 3 months postoperatively, and the patient had a good prognosis without reoperation. (C) A 25‐year‐old female underwent one‐stage bilateral THA with S‐ROM modular stems. Subtrochanteric shortening osteotomies were performed due to high hip dislocations. Postoperative radiograph showed a fracture line of the distal femur on the right side. The prophylactic cerclage wires were bound, reoperation was avoided, and bone union was observed at the 6‐month follow‐up
