Treatment of Unstable Distal Clavicle Fractures (Neer type IIb): A Modified System using a Miniature Locking Plate with a Single Button
Background: Distal clavicle fractures were common in shoulder injuries. This study described the novel fixation technique using a miniature locking plate with a single button and reported its clinical outcomes obtained in patients with distal clavicle fractures associated with coracoclavicular ligaments disruption.
Methods: Seven patients with distal clavicle fractures were included with a follow-up period of 12 months. All patients were diagnosed type IIb fractures according to the Neer classification. Distal clavicle fracture was fixed with a miniature locking plate and coracoclavicular ligaments were reconstructed using a single button. Functional outcomes were assessed at the final follow-up visit.
Results: At 1-year follow-up, all patients had achieved radiographic union. There were no cases of nonunion or osteolysis. Mean Constant score at final follow-up was 88±5.13 (range, 78-93). Mean DASH score was 19.17±7.70 (range, 11.67-25). Mean UCLA score was 30±2.52 (range, 25-33).
Conclusions: Internal fixation using a miniature locking plate and coracoclavicular reconstruction with a single button were reliable surgical techniques for restoring stability in patients with Neer type IIb distal clavicle fractures.
