末梢神経損傷の診断と治療における最先端

The undulating characteristics of nerve fibers and the endoneurium are important factors in resisting traction force. The diagnostic accuracies of magnetic resonance neurography and ultrasonography for nerve injuries are 85.4% and 70.6%, respectively. Epineurial repair is the most commonly used nerve repair technique. Nerve grafts are generally required when the defect exceeds 2 cm. Nerve transfers are primarily indicated for brachial plexus root avulsions or intraforaminal lesions. Painful neuromas can be treated with target muscle reinnervation. Surgery yields reliable results for carpal-tunnel syndrome, cubital-tunnel syndrome, the common peroneal nerve entrapment, and the lateral femoral cutaneous nerve entrapment syndrome. Effective rehabilitation interventions related to the central nervous system include sensory reeducation, cross-modal sensory substitution, motor imagery, and action observation with simultaneous peripheral nerve stimulation.
