SUMMARY: The present study was undertaken to quantitate the incidence and clinical patterns of peripheral nerve dysfunction distal to the level of injury in patients with spinal cord injury (SCI). Through retrospective analysis, SCI patients were identified after referral for neurophysiologic investigation of new neuropathic symptoms. In total, peripheral nerve or nerve root lesions developed in 34 SCI patients, most commonly within the first year after SCI. Carpal tunnel syndrome was the most common upper-limb neuropathy (34%); sciatic neuropathy was the most common lower-limb abnormality (8.5%). A significant proportion of SCI patients had neurophysiological evidence of generalized peripheral nerve dysfunction, specifically axonal neuropathy (18%). Tetraplegic patients developed more frequent peripheral nerve lesions than paraplegics. Although most SCI patients presented within 4 years of their original injury, in a more chronic population of SCI patients that developed neuropathy 5 years after injury, 60% had evidence of coexistent syrinx formation. Maintenance of peripheral nerve function is a critical issue in all acute SCI and rehabilitation units, particularly in the context of spinal cord neuronal regeneration projects.
