Which lateral clavicle fractures can be treated by an arthroscopic-assisted endobutton procedure? An analysis of risk factors.

Our study shows that arthroscopy-assisted CC stabilization using an endobutton technique delivers good functional results. Highly lateral unstable clavicle fractures seem to be especially suitable for this surgical technique. There was a high number of delayed unions. Analysis of risk factors showed that early mechanical stress, a lateral clavicular fragment larger than 3 cm and a time delay to surgery could be risk factors for nonunions.
