Repair of acromioclavicular separation using a dacron prosthesis graft.

Twenty patients were treated for acute acromioclavicular separation using a Dacron vascular prosthesis and followed for an average period of 13.1 months. None demonstrated loss of motion, or muscle weakness. All resumed their prior level of athletic activity. Satisfactory results were obtained in 18 patients. Residual deformity was the primary reason for an unsatisfactory rating. Recurrence of deformity can be minimized by technical skill and perfection of the surgical reduction.
