We have studied the result of a modified Weaver-Dunn technique using absorbable sutures and imbrication of deltotrapezial fascia for the treatment of the dislocation of acromioclavicular joints.

Seventeen dislocations treated with the operative technique. Followed-up after at least 18 months postoperatively were retrospectively analyzed using the UCLA rating scale score, radiological films and occurrence of postoperative complications.

Overall results were excellent in 7 (41%), good in 8 (47%) and poor in 2 cases (12%) according to UCLA rating system. The effect of age on the outcome was not significant but the result was better for early operations than late operations. Forward elevation loss was found in the group that was older than 39 years. The clavicle was anatomically reduced and maintained in 13 cases (76%).

Modified Weaver-Dunn technique using absorbable sutures is a good treatment for acromioclavicular dislocations and imbrication of deltotrapezial fascia is important in stabilizing the joint.
