ABSTRACT
This study presents the results of a minimally invasive operative treatment for markedly displaced midclavicular fractures. In all patients a flexible titanium nail was inserted in an unreamed technique from the sternal end of the clavicle. The result of surgery was determined with clinical and radiographic controls. The clinical outcome was evaluated 12 months after hardware removal using the scoring system of Constant and Murley. Fifty-eight fractures in 55 patients were treated with intramedullary fixation. Postoperatively on Day 3, the mean subjective pain was significantly lower and range of motion was improved compared with the day before surgery. One nonunion occurred. There was no infection and no implant displacement or refracture. Intramedullary nailing of midclavicular fractures with a flexible titanium nail is a safe minimally invasive surgical technique with excellent functional and cosmetic results compared with plate fixation or conservative treatment. Marked pain reduction along with early restoration of shoulder function and early mobilization are advantageous for patients. This technique can be used as an alternative treatment to conservative procedures or plate fixation in patients with markedly displaced midclavicular fractures, multiple trauma, fractures of the lower extremities, or associated shoulder girdle injuries.
