Joplin's neuroma or compression neuropathy of the plantar proper digital nerve to the hallux: clinicopathologic study of three cases.

Both nonsurgical and surgical treatment of compressive and/or entrapment neuropathy of the plantar proper digital nerve to the hallux, also known as Joplin's neuroma, are very uncommon in the literature. The condition of perineural fibrosis of this nerve was first described in 1971 by Joplin. Diagnosis of this nerve in a localized pathologic process based on physical exam and surgical pathology and noniatrogenic etiology are discussed. Three case studies of Joplin's neuroma are followed through the treatment course from initial presentation to postoperative follow-up.
