    Abstract:
    BACKGROUND: The need for operative treatment of acute acromioclavicular (AC) joint dislocation is unclear. The purpose of this randomized controlled trial was to compare the outcomes after operative treatment with a hook plate with the outcomes after nonoperative treatment of acute Rockwood type III and type V AC joint dislocations separately. METHODS: The inclusion criteria were patients aged 18-65 years with an acute type III or type V AC joint dislocation with the availability to start treatment within 3 weeks after trauma. All patients received the same standardized outpatient rehabilitation protocol and were followed up for 24 months. Assessments were based on radiographs, clinical examination findings, and questionnaires. The primary outcome was the Constant score (CS). The secondary outcomes were as follows: Subjective Shoulder Value (SSV), QuickDASH score (abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire), shoulder pain at rest and during movement rated using a visual analog scale, EQ-5D (European Quality of Life 5 Dimensions) score, patient satisfaction, cosmesis, complications, and adverse events. The 4 groups were compared using 1-way analysis of variance and intention to treat. RESULTS: The included patients (N = 124) (mean age, 40 years [range, 18-64 years]; 91% male patients) were randomized, stratified by type, to nonoperative treatment (type III, n = 33; type V, n = 30) or operative treatment with a hook plate (type III, n = 30; type V, n = 31) at a single center. Three patients randomized to physiotherapy dropped out before any follow-up measures, leaving 121 patients in the study. Complete clinical follow-up data were obtained from 118 patients at 24 months. At 3 months, patients in both nonoperatively treated groups had a significantly better mean CS, SSV, and QuickDASH score and had less pain at rest and during movement compared with patients treated operatively. At 6, 12, and 24 months, there were no significant differences in the CS, SSV, QuickDASH score, pain, or EQ-5D score between the groups regardless of intervention. At 24 months, the mean CS was 88 for nonoperatively treated type III patients vs. 91 for operatively treated type III patients and was 90 vs. 91 for type V patients (P = .477). At final follow-up, patients had regained 97% of the mean CS comparing the uninjured and injured shoulders and 86% of the patients rated the result as excellent or good. Eleven patients assigned to nonoperative treatment (18%, 6 type III and 5 type V) underwent surgery within 19 months. CONCLUSIONS: Both the nonoperative and operative treatment groups had very good restoration of shoulder function and patient satisfaction at 24 months, and operative treatment did not lead to better outcomes compared with nonoperative treatment. In conclusion, our study does not support surgery with a hook plate in patients with acute Rockwood type III or type V AC joint dislocations.
