A benign cortical defect in a bone may present itself as a weak site for muscle attachment resulting in an avulsion injury. Such a benign cortical defect may be mistaken for a malignant tumor when the avulsion injury excites irregular, laminated periosteal reaction. We report three patients in whom avulsion fractures occurred at the site of pre-existing benign cortical defects in the distal femur.
骨皮质的良性缺损可能表现为肌肉附着的薄弱部位，从而导致撕脱伤。当撕脱伤引发不规则的、分层状的骨膜反应时，这种良性皮质缺损可能会被误诊为恶性肿瘤。我们报告了三例患者，他们的股骨远端先前存在良性皮质缺损部位发生了撕脱骨折。
