Preliminary results of the use of Ilizarov fixation in clavicular non-union

Although clavicular fractures are common, nonunion of clavicle is a rare complication. Clavicular nonunion that occurs due to insufficient stabilization is usually painful and necessitates operative treatment. Seven cases with oligotrophic clavicular nonunion that developed after a conservative process were treated with Ilizarov between January 2000 and December 2002. In all of them, the middle one-third of the clavicle was affected. Details of the cases regarding sex, age information, reason of fracture, previous treatment methods that were applied, nonunion area, nonunion, and duration of frame application were recorded. Two of the cases were female and five of them were male with age mean of 27.1 (19–32 years). Five of these cases had right clavicular injury and two of them had left clavicular injury. Mean nonunion duration was 18 months (range was 6–36 months). All nonunion were fixed and went through acute compression by means of Ilizarov’s external fixators without grafting. The duration between the frame application and union was mean 2.7 months (range was 2.5–3.5 months). Mean follow-up period was 31 months (range was 22–48 months). Cases were evaluated in accordance with the Constant Scoring system. They were able to return to their normal daily activities in 10–15 days. All of them regained full shoulder movement and extension ability. Patients have also been evaluated by using Dash-Score. Union existed for all patients and none of them had any complaints of pain after treatment. Since circular external fixator allows acute compression, early shoulder movements, and requires no such additional procedure as grafting, it is an alternative method which can be used in treating nonunion of clavicle.
