Onychoclavus due to subungual exostosis: Reconstruction of the resulting defect by triple volar advancement flap: Surgical technique

Abstract

Onychoclavus is a hyperkeratotic corn tissue in the nail region. Subungual exostosis is an osteochondral tumor arising from the distal phalanx of the great toe. Dorsolateral defects of toes require special flap techniques. A 25-year-old male patient applied to outpatient clinic with the complaint of a tender mass under his left toe nail. Hyperkeratotic parts of skin and underlying exostosis were removed. The resulting defect was repaired by using the triple volar advancement flap technique. Patient satisfaction was very high and there was no recurrence after 12 months of follow up. The triple volar advancement flap technique is very suitable for dorsolateral toe tip defects because reconstruction is performed easily and a natural appearance is achieved. Treatment of onychoclavus due to underlying bony exostosis is an excellent indication for this flap technique because both excision and reconstruction are carried out easily with this special surgical technique. © 2011 by Türkiye Klinikleri.
