[Effectiveness analysis of Endobutton plate combined with high-strength suture Nice knot fixation in the treatment of distal clavicle fractures].

Abstract

OBJECTIVE:

To investigate the effectiveness of Endobutton plate coracoclavicular fixation combined with fracture site high-strength suture Nice knot cerclage fixation in the treatment of distal clavicle fracture with coracoclavicular ligament injury.

METHODS:

The clinical data of 33 cases of distal clavicular fracture with coracoclavicular ligament injury treated by Endobutton coracoclavicular plate fixation between January 2017 and December 2020 were analyzed retrospectively. According to the fixation methods of fracture site, they were divided into two groups: the high-strength suture Nice knot fixation group (study group, 16 cases) and the transacromial Kirschner wire fixation group (control group, 17 cases). There was no significant difference between the two groups in common data such as age, gender, injury side, cause of injury, Craig type, combined injury, time from injury to operation, and preoperative visual analogue scale (VAS) score and Constant-Murley score ( P>0.05). Postoperative fracture healing and complications were observed, and the increase rate of coracoclavicular space on the affected side was calculated at last follow-up. VAS score was used to evaluate shoulder pain before operation, at 1 week, 1 month, 3 months after operation, and at last follow-up. The shoulder function was evaluated according to Constant-Murley shoulder score before operation, at 1 month, 3 months after operation, and at last follow-up.

RESULTS:

The operations were successfully completed in both groups without severe complications such as vascular nerve injury and coracoid fracture. In the control group, 1 case (5.9%) had slight pin tract infection and 1 case (5.9%) had Kirschner wire displacement; there was no obvious complication in the study group. The patients in both groups were followed up 9-36 months (mean, 22.9 months). The fracture healing time of the study group and the control group were (12.56±0.73) weeks and (13.59±0.87) weeks, respectively, and the difference was significant ( t=-3.661, P=0.001). At last follow-up, the increase rates of coracoclavicular space on the affected side of the study group and the control group were 8.88%±1.19% and 8.55%±1.07%, respectively, showing no significant difference ( t=0.837, P=0.409). The postoperative VAS score and Constant-Murley score of the two groups significantly improved when compared with those before operation, and the two scores gradually improved with the extension of time after operation ( P<0.05). Except that the VAS score at 1 week and 1 month after operation and the Constant-Murley score at 1 month after operation in the study group were significantly better than those in the control group ( P<0.05), there was no significant difference between the two groups at other time points after operation ( P>0.05).

CONCLUSION:

For oblique fracture or combined with butterfly fracture in the distal clavicle fracture with coracoclavicular ligament injury, the fracture site high-strength suture Nice knot fixation is a good supplement to the Endobutton plate coracoclavicular fixation. It can stabilize the fracture end, reduce the complications of Kirschner wire fixation, and is more conducive to fracture healing. The effectiveness is satisfactory.
