[Clinical study on surgical repair of acute acromioclavicular dislocation by modified Weaver-Dunn technique]
1Department of Orthopedic Surgery, Shanghai 6th People's Hospital, Shanghai, P. R. China 200233.
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).
Conclusion:
The modified Weaver-Dunn technique was a better surgical approach than tension band fixation for repair of acute acromioclavicular dislocation.
