Results of distraction callus osteogenesis in hand and foot in Iran: A 15-year experience

Abstract

Background: Distraction osteogenesis (DS) is currently an important technique for lengthening shortened bones of the hand and foot. Authors report their experience in applying DS for various conditions of the hand and foot using a distractor that the senior author has designed. Materials and Methods: Records of patients who underwent DS for hand and foot conditions in a private clinic were retrieved between January 2001 and January 2015. Data concerning distraction, outcome, and complications were recorded.Results: There were 17 patients, 7 males, and 10 females with a total 24 distractions. The mean length gained was 21.2 mm (1.69) and the mean total treatment time was 198.58 (15.88) days. Overall, complications occurred in 9 (37.5%) distractions. Major complications occurred in 2 (8.33%) of distractions. Minor complications occurred in 7 (29.2%) distractions. Conclusion: DS is an effective modality for lengthening bones of the hand and feet for both traumatic and congenital conditions. Joint stiff ness/contracture is an important complication following DS of the metatarsals.
