摘要

A 63-year-old man reported numbness in his left first, second and third digits for 2 years. Initially, he found that 'shaking out' his left hand helped, but this benefit did not last. He underwent decompression of left-sided carpal tunnel syndrome 2 years earlier and his symptoms worsened after surgery, with more sensory loss and pain. He worked as a carpenter, and had injured his left thumb with nails on multiple occasions without feeling pain. On examination, he had an enlarged left thumb (figure 1), though he appeared unaware of this; his other digits were normal in size. The median nerve was palpable at the wrist, but Tinel's test was negative. There was a mild weakness of abductor pollicis brevis and opponens brevis, with reduced sensation over the fingertips of the lateral three digits and palm. Electrophysiological testing confirmed median nerve entrapment at the carpal tunnel, with absent sensory potentials at the third and fourth digits, with prolonged distal motor latency (5.6 ms), and decreased motor compound muscle action potential at the carpal tunnel (compound muscle action potential 2.7 mV).
