[Clinical study on surgical repair of acute acromioclavicular dislocation by modified Weaver-Dunn technique].
OBJECTIVE
To investigate the clinical value of modified Weaver-Dunn technique in repair of acute acromioclavicular dislocation.


METHODS
From January 1993 to December 1998, 18 cases of acromioclavicular dislocation were treated by modified Weaver-Dunn technique, and other 17 cases of the same suffering were treated by tension band fixation of the acromioclavicular joints. All of the patients were followed up for 12-36 months before clinical evaluation of the function of shoulder joints, according to University of Pennsylvanian Shoulder Score System.


RESULTS
In short term, the shoulder joints recovered much more rapidly in the cases repaired by modified Weaver-Dunn technique; 12, 24 and 36 months after operation, the scores of the cases repaired by modified Weaver-Dunn technique were (189.7 +/- 6.7), (193.7 +/- 3.6) and (194.7 +/- 3.4) respectively according to the Shoulder Score System, while those of the cases treated by tension band fixation were (167.3 +/- 7.8), (170.2 +/- 6.3) and (165.6 +/- 5.9) respectively. The above data indicated that there was significant difference between two groups (P < 0.05).


CONCLUSIONS
The modified Weaver-Dunn technique was a better surgical approach than tension band fixation for repair of acute acromioclavicular dislocation.
