[Comparison of the effect of arthroscopy assisted TightRope plate and Triple-Endobutton plate and Double Endobutton plate in the treatment of acromioclavicular dislocation].

OBJECTIVE

To investigate the clinical effect of arthroscopic assisted TightRope plate, Triple-Endobutton plate and Double Endobutton plate in treating of Rockwood type Ⅲ-Ⅴ acromioclavicular dislocation.

METHODS

From January 2014 to January 2018, 128 patients with acromioclavicular dislocation were treated by operation. According to the operation plan, the patients were divided into three groups:Double Endobutton group, Triple-Endobutton group and TightRope group. All patients with acromioclavicular dislocation were operated by the same operation team, and the chief surgeon was the same chief physician. General baseline data such as gender, age, operation time, incision length, intraoperative blood loss, VAS score of pain and Constant-Murley shoulder function score were recorded.

RESULTS

The wound healed well and no recent complications occurred. One hundred and eleven patients were followed up for 6 to 12(9.1±3.1) months. There was no significant difference on general data among three groups (P >0.05). Among three groups, the operation time of Triple -Endobutton group was the longest, significantly higher than that of other two groups(P<0.05);the operation time of TightRope group was the shortest, significantly lower than that of other two groups (P<0.05). At 1 month after operation, VAS score comparison of three groups, TightRope group was significantly lower than other two groups, with statistical difference (P<0.05). At 12 months after operation of three groups, the Constant-Murley score of TightRope group was significantly higher than that of two group (P<0.05). The incidence of incision infectionin TightRope group was significantly lower than that of other two groups(P<0.05); the incidence of reduction loss in Double Endobton group was significantly higher than that of other two groups(P<0.05), the incidence of reduction loss in TightRope group was significantly higher than that of Triple endobton group(P<0.05);the incidence of joint adhesion in TightRope group was significantly lower than that of other two groups(P<0.05).

CONCLUSION

TightRope plate fixation with arthroscopy is more advantageous than Double Endobutton plate fixation and Triple-Endobutton plate fixation.
