A New Method for Acromioclavicular Joint Dislocation
-Using Two Flip Buttons-

Abstract

We report a new method for acromioclavicular(A-C) joint dislocation using two flip buttons and fiberwire.
We refered to MINAR(Minimally Invasive AC joint Repair) reported by Wellmann et al, and made an original drill guide using bent elevatrium. A 4.5-mm drill was used to create a pilot hole in the base of the coracoid. A fiberwire loop was threaded through the internal eyelets of a flip button. Then, the prepared flip button was pushed through the coracoid drill hole and placed under the coracoid base. One end of the flip button was then passed through a 4.5-mm drill hole placed through the clavicle in line with the base of the coracoid. Afterward, repositioning the clavicle end, the fiberwire loop was tied. Operation time was about 50 minutes. We concluded that a new method for A-C joint dislocation using two flip buttons and fiberwire is very useful.
