Purpose: From 1983 to 1992, we performed modified Cadenat's procedure using a Kirschner wire as a temporal internal fixator for a complete dislocation of the acromioclavicular joint. Since 1993, the Kirschner wire was changed to a Wolter clavicular plate, because the Kirschner wire fixation induced OA changes in the acromioclavicular joint and recovery to the preoperative shoulder ROM was delayed. In this study, we wish to report our experience in the ues of Wolter clavicular plate as temporal internal fixator.
Material and methods: Eighteen patients with a complete acromioclavicular dislocation underwent Cadenat's procedure, in which a Wolter clavicular plate was used as a temporal internal fixator in our hospital. Fifteen cases were male and 3 cases were female. The age distributed from 21 to 58years(mean: 36.1 years)at the time of surgery.
Results: We used Kawabe's scoring; 17 cases were excellent,1 case was good, with a mean value of 96.0points. A sling was applied for postoperative immobilization for 2.0 weeks. Recovery of shoulder elevation over 135 degrees required 8.5 weeks. As postoperative complication; an acromional fracture occurred in 1 case. Osteoarthritic change occurred in 2 cases. Postoperative subluxation of the acromioclavicular joint occurred 33.3%.
Conclusion: As a temporal internal fixator, use of the Wolter clavicular plate revealed more excellent postoperative results than that of a Kirschner wire for a modified Cadenat's procedure. Patients returned to work earlier with a Wolter clavicular plate.
