Abstract

The most common locations of the corn are on top of the dorsal lateral aspect of the fifth toe and in the interdigital space between the fourth and fifth toes. Lateral fifth toe corns form as a result of extrinsic pressure from footwear. Interdigital corns form over the condyles of the phalanx between the toes, and can be soft and very painful in most cases. When conservative treatment fails, surgical treatment is indicated. Surgical treatment consists of partial or complete condylectomy and syndactylization. However, it is difficult to correct interdigital corns because of the narrow webspace and risk of painful postoperative scar. No prior study has been published on minimally invasive surgery for lateral fifth toe and interdigital corns, with the exception of some publications on the explanation of the technique. We investigated six toes from five patients using a minimally invasive surgical procedure that consisted of partial condylectomy with correction of associated deformities. We achieved successful results in the absence of major complications or recurrence during one year follow-up periods. This is the first case series that reports on minimally invasive surgery for painful toe corn.
