Clavicular nonunions treated with compression plate fixation and cancellous bone grafting: the functional outcome.

We evaluated fracture healing and functional outcome after surgery in 16 patients with midshaft clavicular nonunion. The operative treatment consisted of compression plate fixation and autologous cancellous bone graft. The follow-up examination took place at an average of 54 months (range 26 to 90 months) after surgery. Radiographs were reviewed, and 12 patients underwent clinical review. All fractures united successfully. Two patients had a second operation because of loosening of the screws shortly after the first operation. Eleven of 12 patients had a good or excellent Constant score (>70 points). Nine of 12 patients returned to their preinjury activity level. Treatment with compression plate and autologous cancellous bone graft yields a high rate of healing and an acceptable functional outcome.
