Entrapment Neuropathy sometimes referred to as Baxter’s Nerve Entrapment results from compression of a nerve that supplies the plantar (under) surface of your foot. This nerve is also known as the inferior calcaneal nerve.
Plantar Fasciitis and Baxter’s Nerve are sometimes confused due to the similarity or the location of pain. In Baxter’s Nerve Entrapment distinct tenderness is felt at the origin of the abductor hallicus muscle (a small muscle along the inside of the foot), whereas the most intense site of pain in Plantar Fasciitis is more commonly towards the bottom of the heel.
Unlike Plantar Fasciitis, pain associated with entrapment tends to get worse with physical activity. Pain is more localized and it is pressure sensitive. Custom shoe orthotics may aggravate the pain if they have been prescribed to address a different diagnosis due to the orthotic further compressing the nerve.
When pain levels fail to improve with conservative treatment or cease for a short time after injection therapy only to return, surgery for Baxter’s Nerve Entrapment known as neurolysis may be indicated and may also be combined with a plantar fascia release.
