The author reports a case of isolated traumatic volar dislocation of the ulnar head in the distal radioulnar joint. This fairly uncommon injury is seldom accurately diagnosed at first presentation because there is no distinct deformity at the wrist and extension-flexion is normal and painless. However pronation is always restricted and painful. A dislocation of this joint may be simple or complex and the treatment varies accordingly. Because the dislocation in this patient had occurred more than two months previously, surgical reduction failed and resection of the distal ulna using Darrach's procedure was performed.
作者报告了一例尺骨头在桡尺远侧关节处孤立性创伤性掌侧脱位的病例。这种相当罕见的损伤在初次就诊时很少能得到准确诊断，因为腕部没有明显畸形，屈伸正常且无痛。然而，旋前总是受限且疼痛的。该关节脱位可能是单纯性或复杂性的，治疗方法也相应不同。由于该患者的脱位发生在两个多月前，手术复位失败，遂采用达拉赫手术切除尺骨远端。
