Avulsion fractures of the lesser trochanter in adults are almost always due to metastatic bone disease. Familiarity with this characteristic association can lead to early diagnosis and assist the orthopaedist in implementing effective management. We report three patients with avulsion of the lesser trochanter due to neoplasm. In one patient, this was the first sign of metastatic disease; in another patient, there was no history of a primary neoplasm and the avulsion was the first evidence of disease.
成人小转子撕脱性骨折几乎总是由转移性骨病引起。熟悉这种特征性关联可实现早期诊断，并有助于骨科医生实施有效的治疗。我们报告了3例因肿瘤导致小转子撕脱的患者。其中1例患者，这是转移性疾病的首个迹象；另1例患者，无原发性肿瘤病史，撕脱是疾病的首个证据。
