Results of minimal invasive coracoclavicular fixation by double button lift-up system in Neer type II distal clavicle fractures

Abstract

Aim: We aimed to evaluate clinical and functional outcomes of indirect fracture reduction performed by coracoclavicular fixation with minimal invasive double button lift-up system in Neer type IIa unstable fractures of distal clavicle. Material and methods: 22 patients withNeer type 2 distal clavicle fracture were enrolled in that prospective study.All patients underwent indirect reduction and osteosynthesis performed by coracoclavicular fixation with minimal invasive double button lift-up system. Postoperative follow-up was carried out clinically and radiologically with plain X-rays and utilization of Constant andAmerican Shoulder and ElbowSurgeons Standardized Shoulder Assessment (ASES) shoulder scores. Mean follow-up time was 15months.Astandard slingwas applied for 2weeks, postoperatively.Rehabilitation programwas started on postoperative day 1. Results: Mean age was 39 (range: 21-60), 18 of the patients were male. Right dominant extremity was affected in 14 patients. Mean duration of the surgical intervention was 40 min (range: 30-55 min). Mean union time was found to be 14 weeks (range: 7-21 weeks). Mean postoperative ASES and Constant scores were 79.9 (66.9-88.3) and 82.2 (71-100), respectively. The duration of return to normal daily activities were found to be 4.5 months. Any loss of reduction, AC joint arthrosis, and clavicular shortening were not detected in X-rays. Conclusion: This study has demonstrated that indirect osteosynthesis performed by coracoclavicular fixation with double button lift-up system in the treatment of unstable Neer type IIa fractures of the distal clavicle had successful clinical, radiological, and functional outcomes.
