[Technique of intramedullary osteosynthesis of the clavicle with elastic titanium nails]

Abstract

This prospective controlled clinical trial was performed to assess fracture healing and clinical outcome after intramedullary nailing of midclavicular fractures. Within 3.5 years elastic-stable intramedullary nailing was performed in 62 patients with 65 midclavicular fractures. Surgery was performed in supine position. The ventral cortex of the proximal clavicle was opened using a 2.5 mm drill. The nail was advanced laterally under fluoroscopic control. If closed reduction failed, an additional incision was made to enable direct manipulation of the fragments. There were no infections, no implant displacements or refractures. Postoperatively, the mean subjective pain was significantly lower, and the range of motion improved. We observed one nonunion. The mean Constant-score 6 months after hardware removal was 96.9 +/- 3.3 points. Intramedullary fixation of midclavicular fractures with an elastic titanium nail is a safe minimally invasive surgical technique, producing excellent functional and cosmetic results.
