[The status of therapy of acromioclavicular joint injury. Results of a survey of trauma surgery clinics in Germany].

The therapy of acromioclavicular dislocations remains controversial. In particular, for injuries classified as Rockwood/Tossy Type III good results have been reported with different operative techniques as well as with conservative treatment. The objective of this study was to obtain data about the current treatment for Rockwood/Tossy III injuries in German trauma departments. In a countrywide anonymous survey 210 German trauma departments were asked about their diagnostic procedures and their treatment strategies for acromioclavicular injuries. 104 questionnaires (49%) were returned and evaluated. In Rockwood/Tossy I/II injuries most clinics recommend conservative treatment (Rockwood/Tossy I/II: 99%/87%). On the other hand, 84% of the clinics would operate on Type III acromioclavicular injuries--especially in athletes or overhead workers. Although 38 percent of the clinics believe that conservative treatment is equal or better than operative treatment, only 13 percent manage Type III injuries conservatively. For more severe acromioclavicular injuries (Rockwood IV to VI) all clinics recommend an operative treatment. The operative techniques of choice for acromioclavicular injuries are K-wire fixation (37%) or a coraco-clavicular cerclage (32%). Of the latter, 73% use a resorbable material, while the remainder use wires.
