1. Twenty-four cases of acute acromioclavicular-joint dislocation are presented with a follow-up of nineteen treated by open reduction and coracoclavicular screw fixations
2. Methods of non-operative and operative treatment of acromioclavicular joint dislocations are reviewed.
3. A modification of Bosworth's method of coracoclavicular screw fixation is described.
4. Complete reduction of the dislocation appears to be essential for an excellent functional result.
