Morton's
Neuroma
© 1999-2001 by Seth A. Rubenstein, D.P.M.
Certain
activities such as running, tennis, soccer, or use of tight-fitting
shoes may cause the metatarsal bones to lean in toward one another,
temporarily pinching a nerve.
If the nerve is irritated it can swell, becoming a larger "target"
upon which the bones may press. As the process continues, the nerve
becomes chronically swollen, scarred and damaged.
The damaged nerve is frequently called neuroma, or Morton's Neuroma,
after the physician who first described it. The nerve most commonly
involved lies between the second and third or third and fourth metatarsal
heads (ball of the foot). The intermetatarsal nerves travel along
the underside of the foot, between the metatarsal bones. As they
approach the ball of the foot they pass under a thin ligament connecting
the head of the metatarsal bones. This produces a tight canal defined
by the metatarsal heads and ligament.
Treatment
for a newly developed Neuroma is directed at relieving pressure
on the nerve, using wider shoes, arch supports to limit pronation
(rolling in of the foot) and antiinflammatory medication.

If symptoms persist, the inflamed nerve will frequently respond
to a series of two or three steroid injections, combined with
an arch support or functional orthotic. If this fails to reduce
the pain sufficiently, surgery is recommended as a definitive
treatment.
