Lateral Plantar Nerve Entrapment

The lateral plantar nerves branches off from the tibial nerve. If the lateral plantar nerve gets trapped, it results in pain which can radiate to the lower part of heel and ankle. This condition affects around 20% of patients. Forceful or continuous activity tends to worsen the symptoms. If this condition is ignored and not treated promptly then the continuous pressure on the nerve results in paresthesias along the plantar nerve distribution and weakness of the abductor digiti minimi muscle. Other causes for heel pain such as plantar fasciitis should be ruled out before starting treatment as the symptoms are similar.

Treatment comprises of rest, orthotics, NSAIDs, corticosteroid injections and surgery as a last resort.
