Does cerclage wiring interfere with fracture healing of osteosynthesis in comminuted midshaft clavicle fractures? A multicenter study

Historically, cerclage wires were not used in the treatment of clavicle fractures because of their invasiveness. The purpose of this study was to evaluate the radiologic results and the incidence of complications following cerclage wire application and plate fixation in the treatment of comminuted mid-shaft clavicle fractures.

A total of 116 patients with comminuted mid-shaft clavicle fractures who underwent open reduction and internal fixation were reviewed. We analyzed the postoperative length ratio and bone union period according to the fracture classification, patient age, the number of fragments and the number of applied wires. The thickness of the fracture site was compared with the normal contralateral clavicle shaft.

Bone union was confirmed in all enrolled patients at an average of 14.9±4.67 weeks. There are no significant differences in the length ratio or bone union period among the subgroups (including the fracture types, age, number of fragments and applied wires). The diameter at the occupied area was not significantly from that on the normal side (p=.505).

The application of a single cerclage or multiple cerclage wires around the fracture site did not hamper the clavicle shaft fracture healing. This result suggests that cerclage wires should not be avoided, but can be used as a viable treatment option for clavicle shaft fractures.
