Posttraumatic osteonecrosis of distal pole of scaphoid is an extremely rare with only two reported cases so far. We present a case of a 30-year-old male with a 2-year-old posttraumatic osteonecrosis and nonunion of distal pole of scaphoid left wrist. He presented with complaints of pain and restriction of movements. There was no evidence of radiocarpal arthritis. He was managed with open reduction and internal fixation with k-wires, supplemented by a pronator quadratus based muscle pedicle bone graft. The fracture union was achieved at 6 months. After 2 years, he had almost complete range of wrist motion and had returned to his preinjury level of functional activity. His MRI (magnetic resonance imaging) scans showed evidence of revascularization suggesting successful incorporation of bone graft.
舟骨远极创伤后骨坏死极为罕见，迄今为止仅有两例报道。我们报告一例30岁男性病例，其左腕舟骨远极创伤后骨坏死且骨不连已有2年。他因疼痛和活动受限前来就诊。没有桡腕关节炎的迹象。对其进行了切开复位并用克氏针内固定治疗，辅以旋前方肌蒂骨瓣移植。骨折在6个月时愈合。2年后，他的腕关节活动范围几乎完全恢复，已恢复到受伤前的功能活动水平。他的MRI（磁共振成像）扫描显示有血管再生迹象，提示骨瓣成功整合。
