Abstract
|
|
|
|
The first branch of the lateral plantar nerve (FBLPN) typically arises from the lateral plantar nerve (82.1%) and a small mixed motor and sensory nerve, which innervates the abductor digiti quinti muscle. The entrapment of FBLPN accounts for 20% of medial heel pain and is commonly confused with plantar fasciitis, fat pad atrophy, and lumbosacral radiculopathy. Proper diagnosis and management require the use of objective diagnostic tools such as electromyography, magnetic resonance imaging, and ultrasonography. Here we describe the unusual case of a patient misdiagnosed with lumbosacral radiculopathy due to neurogenic symptoms and who was correctly diagnosed with neuropathy of FBLPN by electromyography.
