The authors present a review of 34 clinodactylies. We observe 16 delta phalanx, 12 congenital angular inclination, 6 thumb abnormalities. The procedure is required when the angulation is superior to 40 degrees. In this study, 16 cases had surgical treatment (10 digits, 6 thumbs). Additional osteotomy or subtraction osteotomy were performed. The authors prefer this last one. The age of procedure is 4 years. The surgical treatment is difficult and the authors prefer abstention if there is no functional troubles with the growth.
