Abstract:

BACKGROUND: The most common method for acromioclavicular joint dislocation is hook plate fixation. The randomized studies about different surgical treatments of type III acromioclavicular joint dislocation are seldom. Most of them are retrospective case analysis, and systematic evaluation is missing.
OBJECTIVE: To systematically evaluate clinical outcomes and safety between different surgical methods for type III acromioclavicular joint dislocation.
METHODS: Cochrane central register of controlled trials (No. 2 in 2013), PubMed (1966-01/2013-08), Medline (1966-01/2013-08), EMbase (1984-01/2013-08), CNKI (1979-01/2013-08) and VIP (1989-01/2013-08) were searched by computer. Six kinds of Chinese magazines about orthopedics were searched by hand. References of relevant literatures were searched. Randomized controlled trials that were related to different surgical methods for the treatment of type III acromioclavicular joint dislocation were collected. In accordance with inclusion criteria, some literatures were included. Their qualities were assessed strictly. Meta-analysis was performed with RevMan  5.2 software from the Cochrane collaboration.
RESULTS AND CONCLUSION: 108 potentially relevant papers and 7 published studies with randomized controlled trials met all the inclusion criteria. A total of 381 patients were included, containing 193 cases of clavicle hook plate fixation, 115 cases of double Kirschner’s tension band wires fixation, 9 cases of screw fixation, 35 cases of endobutton plates, and 29 cases of internal fixation. One research addressed treatment with three ways, and the remaining were about two ways. Meta-analysis showed that the excellent rate was better in clavicle hook plate fixation than in double Kirschner’s tension band wires fixation for acromioclavicular joint dislocation (P=0.005), but poorer than endobutton plates (P=0.04), and no significant difference was detected as compared with screw fixation and internal fixation (P=0.82, P=1.00). As compared with other therapeutic manners, there were significant differences in shoulder joint pain, fixator ineffectiveness, redislocation, operation time and medical cost (P=0.05, P=0.04, P=0.02, P < 0.000 01, P=0.000 6), but no significant difference was detected in complications and bleeding amount (P=0.71, P=0.35). Results indicated that compared with other fixation manners, the efficiency of clavicle hook plate fixation for acromioclavicular joint dislocation was better than double Kirschner’s tension band wires fixation, but poorer than endobutton plates, which caused shoulder pain and shoulder joint movement disturbance. Fixator ineffectiveness or redislocation seldom occurred. Operation time was short and medical expenses were low. There was no significant difference in complications and bleeding amount. Because the number of cases in this study is few, we should design more strictly large-sample randomized controlled studies to increase the strength of the evidence.
