目的 :探讨高原地区腕舟骨腰部骨折的X线征象及预后。方法 :回顾了 4 6例资料完整的病例 ,均照腕关节正侧位片 ,大部分加照蝶式位片。结果 :舟骨腰部多为横行、斜行骨折 ,伴桡侧脂肪垫征阳性 ,可有旋转移位。常并发桡尺骨远端骨折。骨折不愈合、延迟愈合、缺血坏死、创伤性关节炎多见。结论 :蝶式位对诊断舟骨腰部骨折有重要意义。舟骨腰部的血供特点及高原环境导致预后不良。骨折线的形态及骨折移位情况对预后亦有影响。
Objective: To investigate the X-ray findings and prognosis of the scaphoid lumbar fracture in the plateau. Methods: A total of 46 cases with complete data were retrospectively reviewed. All the patients underwent lateral radiographs of the wrist joint. Results: The scaphoid mostly rampant, oblique fracture, with radial fat pad sign positive, may have rotational displacement. Often distal ulna fractures. Fractures do not heal, delayed healing, ischemic necrosis, traumatic arthritis more common. Conclusion: The butterfly position is of great importance in diagnosis of lumbar fracture of scaphoid. The scaphoid blood supply characteristics and high altitude environment lead to poor prognosis. Fracture line shape and fracture displacement also have an impact on prognosis.
