DOUBLE BUTTON FIXATION SYSTEM FOR THE TREATMENT OF ACUTE HIGH-GRADE ACROMIOCLAVICULAR JOINT DISLOCATION

Abstract

Background: Acromioclavicular joint injuries represent the spectrum of soft tissue disruptions. These injuries usually occur in young males associated with athletic activities in which a direct blow to the lateral aspect of the shoulder occurs. Athletes belonging to the population at risk individuals, especially those who play football, rugby, or hockey. Conservative management is still considered a better modality for type 1, type 2, and some type 3 injuries. This prospective interven Materials and methods: tional study was conducted on patients who underwent surgery for AC joint dislocation. Mini-open surgery with a double-button xation technique was performed. Rockwood classication types 4-6 were included in the study. Proper pre-operative radiographs were obtained for better planning and management. Follow-up was taken at 2 weeks, 4 weeks, 3 months, 6 months, and 12 months. A total of 24 patients were included in the Results: study, with a mean age of 32.54 years. Among them 19(79.16%) were male and 5(20.83%) were females. According to Rockwood classication, 18(75%) patients belonged to type 4 injuries and 6(25%) patients to type 5 injuries. The mean VAS score at the nal follow-up was 0.16±0.38 which was signicantly improved from the pre-operative value of 6.87±1.15. The improvement in DASH score was from 19.6±2.66 preoperatively to 0.35±1.42 at 12 months postoperatively. There were no complications associated with the procedure. Acute traumatic Conclusion: high-grade acromioclavicular joint dislocations should be treated with operative methods. Double button xation device using a mini-open technique provides adequate exposure, better anatomical xation, and excellent functional outcomes.
