Ulnar nerve palsy results in significant loss of sensation and profound weakness, leading to a dysfunctional hand. Typical clinical findings include loss of key pinch, clawing, loss of normal flexion sequence of the digits, loss of the metacarpal arch, and abduction of the small finger. Further deficits in hand/wrist function are seen in high-level ulnar nerve palsy, including loss of ring- and small-finger distal interphalangeal flexion, decreased wrist flexion, and loss of dorsal sensory innervation. This article reviews the clinical findings seen in low and high ulnar nerve palsies, and reviews surgical options for correcting certain motor and sensory deficits.
尺神经麻痹会导致显著的感觉丧失和严重无力,从而使手部功能失调。典型的临床症状包括捏物功能丧失、爪形手、手指正常屈曲顺序丧失、掌弓消失以及小指外展。在高位尺神经麻痹中还可见手部/腕部功能的进一步缺陷,包括环指和小指远侧指间关节屈曲丧失、腕部屈曲减弱以及背侧感觉神经支配丧失。本文回顾了低位和高位尺神经麻痹的临床症状,并探讨了纠正某些运动和感觉缺陷的手术选择。
