[Elastic, stable intramedullary nailing in midclavicular fractures--a change in treatment strategies?].

Midshaft fractures of the clavicle are mostly treated conservatively. For the few cases in which stabilisation is needed, open reduction and plate fixation is the standard procedure. We report a minimally invasive technique of intramedullary stabilisation using a titanium nail carried out in 35 markedly displaced midclavicular fractures. Twelve fractures were simple and 23 consisted of more than two fragments. A total of 62.9% (22/35) of the patients presented additional injuries; 37.1% (13/35) with additional fractures. There were four ipsilateral scapular neck fractures. In 74.3% (26/35) of patients closed reduction was possible, whereas nine fractures required open reduction before the nail inserted from the sternal end of the clavicle could be introduced into the peripheral fragment. All fractures healed clinically and radiologically within 6 weeks. In contrast to conservatively treated fractures, length discrepancies of 1 cm or more, mainly shortening, could be avoided. Using a visual analog scale, significant pain relief (8.4-2.4 points) was already recorded on the first day after surgery. Patients with an isolated fracture of the clavicle showed a nearly normal range of motion only 1 week after surgery, whereas patients with associated scapular or rib fractures needed up to 3 weeks to reach normal shoulder function. No patient complications requiring interventional procedures occurred. Minimally invasive, elastic, stable intramedullary nailing of midshaft fractures of the clavicle should be recommended as an alternative to conservative treatment because of early pain relief, associated rapid functional recovery and anatomical restoration of the clavicle.
