Digital and interdigital corns: a report of two cases with use of hyaluronic acid gel filler.

Digital and interdigital corns are common painful foot conditions encountered by podiatrists during the course of their practice. These corns can often be treated with conservative techniques, although they tend to eventually recur. Currently, no single treatment exists that is efficient, long-lasting, minimally invasive, and easy to administer. This article describes two cases where hyaluronic acid gel injections were used to improve symptoms associated with digital and interdigital corns located in a nonweightbearing area. Both patients tolerated the intervention well and showed considerable improvement of their condition for a substantial period of time after the intervention without developing adverse reactions. Hyaluronic acid gel injections could very well represent an interesting therapeutic alternative for digital and interdigital corns located in nonweightbearing areas.
