An avulsion fracture of the lesser trochanter in the absence of known or appropriate antecedent trauma was the initial manifestation of unrecognized metastatic malignant disease in the subtrochanteric area of four patients. In three patients the fracture healed but a pathological subtrochanteric fracture then occurred, and in one patient prophylactic nailing of the hip was performed to prevent this fracture. A thorough search for occult metastatic malignant disease should be made whenever this fracture occurs in an adult. Prophylactic internal fixation to prevent or delay a subsequent pathological subtrochanteric fracture seems worth while.
四名患者在小转子区出现隐匿性转移性恶性疾病，最初表现为小转子撕脱骨折，且无已知或合适的前期创伤。三名患者骨折愈合，但随后发生了病理性转子下骨折，一名患者接受了髋关节预防性内固定以预防骨折。成年人一旦发生这种骨折，应彻底检查是否存在隐匿性转移性恶性疾病。预防性内固定以预防或延迟随后发生的病理性转子下骨折似乎是值得的。
