A comparison of nonoperative and operative treatment of type II distal clavicle fractures.

A retrospective study was performed to compare nonoperative and operative treatments of Type II distal clavicle fractures. From a total of 30 diagnosed patients, 16 were identified as receiving nonoperative treatment and 14 open reduction and coracoclavicular stabilization. The average follow-up was 53.5 months for the nonoperative group and 59.8 months for the operative group. All patients were evaluated postoperatively for pain, range of motion, function, and fracture healing as well as for isokinetic strength. Fractures treated surgically achieved union within six to ten weeks. Nonoperative treatment resulted in seven nonunions. There were no significant differences between the two groups in the mean UCLA, Constant, and ASES scores. Nonunion had no significant effect on functional outcome or strength. This study suggests that Type II distal clavicle fractures can be successfully managed nonoperatively. The high incidence of nonunion does not impede a clinical outcome comparable to that achieved by surgical treatment.
