Extensor digitorum brevis
The extensor digitorum brevis muscle is located on the top of the foot. The muscle is attached to tendons that extend to the toes. The extensor digitorum brevis muscle receives signals from the deep fibular nerve. It controls the movements of the all toes except the smallest toe.
Damage or injury to the extensor digitorum brevis muscle from trauma or inflammation can lead to conditions such as foot drop or dorsal midfoot interosseous compression syndrome. These conditions can lead to significant pain or the inability to move the toes. Typically, foot drop occurs when there is also trauma to the deep fibular nerve. Extensor digitorum brevis muscle sprains and pulls are also possible.
If damage to the extensor digitorum brevis muscle is the only cause for the pain in the area, treatment may consist of physical therapy, muscle relaxers, pain medications, anti-inflammatories, heat, ice, or orthopedic devices. Light to moderate exercise is usually recommended to keep the muscle from atrophying (wasting away) during recovery.
