Displaced mid-shaft clavicular fractures: surgical treatment with a pre-contoured angular stability plate

The treatment for displaced mid-shaft clavicle fracture is highly controversial. In the last years, several biomechanical studies showed better functional results after surgical treatment. The purpose of this study is to evaluate the use of pre-contoured angular stability plate in this type of fracture. From June 2005 to July 2009, we have surgically treated 89 patients with displaced clavicle fracture. We have reevaluated 68 patients for a total of 70 interventions. Outcomes were assessed with Constant score, Dash questionnaire and X-rays. The mean follow-up period was 2 years. Excellent and good results were achieved for all the patients revaluated. The mean Constant score was 94.1 pt, and DASH score was 4.1. We had two cases of nonunion (2.9 %), while there was no case of infection and vascular or nervous lesions. A review of the international literature indicates that there is not a largely accepted gold standard for the treatment for displaced mid-shaft clavicle fractures. In the last 10 years, biomechanical and clinical studies have shown that nonoperative treatment for this type of fractures, with marked shortening or diastasis of the clavicle superior to 2 cm, may result in lower functional outcomes or higher percentage of nonunion. Nowadays, a lot of surgical options are available for the treatment for displaced mid-shaft clavicle fractures. Our experience with pre-contoured angular stability plates has shown excellent clinical outcome. On the basis of our study, we support the use of pre-contoured angular stability plate.
