postoperative diagnosis were:6 cases with wrist canal syndrome, 3 with ulnar nerve compression at elbow, and 1 with radial nerve compression at forearm.
术后6例明确诊断为腕管综合征,3例为肘部尺神经卡压,1例为上臂桡神经卡压。
repeated traction and compression on the ulnar nerve during elbow flexion and extension is the anatomical foundation of ulnar nerve compression at the elbow.
