Abstract
INTRODUCTION: Motor nerve biopsy is performed to supplement clinical, serological, and imaging data in the work-up of neuropathies of unknown origin, especially when motor neuron disease is suspected.
METHODS: We describe a surgical technique for biopsy of a motor branch of the superficial peroneal nerve innervating the peroneus longus muscle.
RESULTS: Three patients presented with weakness concerning for motor neuropathy and underwent biopsy of a motor branch of the superficial peroneal nerve innervating the peroneus longus muscle. The surgical technique is described in detail. Biopsied tissue was sufficient for pathological diagnosis. No patient suffered post-surgical sensory or motor deficits related to the procedure. No patient suffered post-surgical complications.
DISCUSSION: Biopsy of the motor branch of the superficial peroneal nerve to the peroneus longus is a safe and effective alternative for motor nerve biopsy and can be easily combined with peroneus longus muscle biopsy.
