Purpose: We described our experience with subungual exostosis in the foot for which we used different surgical technique according as location and size of lesion and revealed excellent results.
Materials and Methods: We experienced 12 cases of subungual exostosis that were treated surgically and followed them more than one year between October 1995 and July 2003. There were nine females and three males. The average age of patients at surgery was 13.4 years. Duration of symptoms was 20.3 months on average. The lesion involved the hallux in nine cases; eight dorsomedial and one dorsolateral aspect of distal phalangeal bone. It involved the second, the third, and the fifth toe in one each; all central aspect of dorsum of distal phalanx. We used surgical technique that involves approaching the exostosis under the nail to preserve nail coverage for lesion in the hallux. The nails were extracted totally but preserved nail bed as much as possible in other toes. Results were based on appearance of the regenerated nail and presence
of recurrence. Excellent results were those in which the nail appeared nearly normal and there was no clinical or radiographic evidence of recurrence. Good results were associated with a minor nail deformity such as ridging, and no evidence of recurrence. Fair results had obvious nail deformity or a minimal asymptomatic recurrence that was discernable only on radiograph. Poor results were associated with a clinically evident symptomatic recurrence.
Results: When the lesion involved hallux, there were six excellent and two good results, and one poor result. All cases that involved other toes revealed good results.
Conclusion: We suggest that different surgical technique might be applied according as location and size of the lesion to achieve satisfactory results for subungual exostosis in the foot.
