Background: Surgical treatment procedures for acromioclavicular [AC] joint dislocation often manifests some complications. Numerous techniques are evaluated, but there is no gold standard method for management of such injuries yet.  
The Aim of the work: The present study aims at evaluating the results of open single adjustable loop for management of acute AC joint dislocation of types: III, IV and V.
Patients and Methods: This study is a prospective cohort work conducted on 20 cases who were subjected to surgical intervention by the adjustable loop fixation system for acute AC joint dislocation. During the follow up phase, Age, sex, dominant hand, injury mechanism, injured side, duration of the monitoring period, shoulder and hand [DASH], time before surgery, pain scores. The average follow-up time was 16.17±4.38 weeks.
Results: Patients' mean age was 34.5±11.5 years, of which four patients [20%] were females, while the rest of them [60%] were males. Pre-operation VAS, post-operation measurements, and constant shoulder scores have all shown very significant differences. On the other hand, the study found no significant differences between right and left coracoclavicular, while two cases of shoulder stiffness were recorded.
Conclusion: As per the results, the adjustable loop fixation system used as a treatment procedure for acute acromioclavicular joint dislocation manifested suitable results and had minimal damage to the soft tissues surrounding the coracoclavicular ligaments.
