Subungual osteochondroma: Nail sparing excision.

Subungual osteochondroma is a relatively uncommon benign bone tumor affecting mostly children and young adults, and is a major source of pain and nail deformity. Treatment consists of marginal excision and meticulous wound closure. In this report, we present three cases of subungual osteochondroma arising from the dorsal aspect of distal phalanx of the great toe, which were managed by marginal excision with preservation of nail apparatus under digital block anesthesia with the use of a ring tourniquet. We emphasize on the use of ring tourniquet made by glove's finger and the technique of preserving the nail apparatus to prevent nail deformity. At final follow-up, there is no evidence of recurrence or nail deformity with good functional and cosmetic result.
