Abstract
Introduction
The optimal treatment for distal clavicle nonunions remains unknown. Small series have reported outcomes following distal fragment excision and various fixation techniques. We present the clinical, radiographic and functional outcomes after superior plating or double (superior and anteroinferior) plating in combination with bone grafting as treatment for distal clavicle nonunions.
Methods
We collected demographic and radiographic data from a consecutive series of ten patients with symptomatic nonunion of the distal clavicle treated since 1998. Functional outcomes were assessed, as well as the visual analogue scale (VAS) score.
Results
The mean clinical follow-up was 41.4 months (range of 12–158 months). The mean radiological follow-up was 30.6 months (range of 3–158 months). All nonunions healed as demonstrated by subsidence of clinical symptoms and radiographic criteria. The average time to union was 3.7 months (range of 2–8 months). The mean The Disabilities of the Arm, Shoulder and Hand (DASH) score was 11.9 (range of 0–62.5) and mean VAS score was 0.9 at follow-up.
Conclusion
This study illustrates good clinical, radiologic and functional outcomes in ten patients with distal clavicle nonunion treated with superior or double (superior and anteroinferior) plating in combination with bone grafting. Double-plating can be considered an alternative to superior plating offering better resistance against the pulling effect of the arm with the use of smaller fixation plates.
