CASE
We encountered a case of entrapment of the ulnar nerve and artery associated with displaced distal radius and ulna fracture. After the closed reduction, a patient noted a severe sensory deficit and had claw hand. Intraoperatively, the proximal edge of the fractured radius was positioned in the space between the ulnar artery and the nerve, and the nerve was entrapped. The entrapment was released surgically with a good 1-year outcome.
CONCLUSION
In cases of distal radius fracture, there is a possibility of entrapment of the ulnar nerve. When neurological symptoms worsen after the reduction maneuver, early nerve exploration is needed.
病例
我们遇到了一例伴有桡骨远端和尺骨骨折移位的尺神经和动脉嵌压病例。闭合复位后，患者出现严重的感觉缺失，并出现爪形手。术中发现，骨折的桡骨近端位于尺动脉和神经之间的间隙内，神经被嵌压。通过手术释放嵌压，1 年的结果良好。
结论
在桡骨远端骨折的情况下，存在尺神经嵌压的可能性。如果复位后神经症状恶化，需要早期进行神经探查。
