Screws are at a safe distance from critical structures after superior plate fixation of clavicle fractures
Injuries to the critical structures underlying the clavicle are possible during open reduction and internal fixation (ORIF) and afterward secondary to prominent screws. The purpose of this study was to identify patients who received chest computerized tomography (CT) scans after clavicle ORIF to evaluate the distance between the screws and the subclavian vessels.
A retrospective review was performed at a single level-one trauma center. Nineteen patients with chest CT scans after superior plate fixation were included. Coronal CT reconstructions were analyzed to determine distances between the subclavian vessels and screw tips along with the prominence of the screws. Vessels within 15 mm of the screw were considered at risk.
None of the screws (0/142) were within 15 mm of the subclavian vessels. Average screw prominence was 1.3 ± 1 mm (range, 0–3.6 mm). One of the 19 patients had a complication, a re-fracture requiring revision ORIF. The remaining 18 patients had no complications, including neurovascular or pulmonary, at the last follow-up.
None of the screws were excessively prominent or within 15 mm of the subclavian vessels. Attentive superior plate fixation of the clavicle with screws is a safe technique.
