Acute, complete acromioclavicular separation.

Twenty-three patients with acute, complete acromioclavicular separation were studied prospectively. Twelve patients were treated non-operatively and eleven were treated operatively. A twelve-month minimum follow-up, using a point system to evaluate clinical results, demonstrated comparable results with and without surgery. Roentgenographic findings did not correlate with the clinical results. Minimum immobilization and early rehabilitation of the shoulder was the recommended treatment of choice.
