Abstract：
METHODS: We report a single case of a closed intra-articular distal humerus fracture in a 28-year-old man with a preexisting fishtail deformity characterized by concavity of the central trochlea and corresponding deformity of the olecranon. The patient was treated with open reduction and internal fixation.
CONCLUSIONS: The case highlights the diagnosis and challenges of treatment. Conventional fixation choices and imaging techniques may need to be altered when treating a fracture with this deformity.

摘要：
方法：我们报告了一例28岁男性的闭合性肱骨远端关节内骨折，其先前存在鱼尾畸形，其特征是中央滑车凹陷和鹰嘴畸形。患者接受切开复位内固定治疗。
结论：该病例突出了诊断和治疗的挑战。在治疗具有这种畸形的骨折时，可能需要改变常规的固定选择和成像技术。
