Plate fixation of clavicle fractures: comparison between early and delayed surgery

Abstract

Background: The optimal treatment strategy for clavicle fractures remains a topic of debate. We evaluated our step-wise treatment protocol for patients with clavicle fractures to determine our success rate of conservative treatment. In addition, we evaluated the incidence of complications after clavicle plate fixation in patients undergoing acute surgery vs. delayed surgery.

Methods: This was a retrospective analysis in which we registered all patients aged 14 years or older with a clavicle fracture between January 2010 and May 2018 and at least 6 weeks' follow-up. Patients who underwent surgery were included from a prospectively maintained database. Functional outcomes were measured by Disabilities of the Arm, Shoulder and Hand and Constant-Murley scores 6 weeks after surgery.

Results: Conservative treatment was successful in 1627 of 1748 patients (93%). Primary fixation was performed in 73 patients (61%) and delayed fixation in 48 (39%). In 8 patients (6.6%), radiologic widening of the acromioclavicular (AC) joint was present after surgery, suggestive of AC injury. The incidence of complications was significantly higher among patients who underwent delayed fixation vs. those who underwent primary fixation: 15 of 48 patients (31.3%) vs. 9 of 73 patients (12.3%).

Conclusion: Most patients with clavicle fractures have an excellent outcome using conservative management. Acute surgery can be performed in high-demand patients, resulting in high performance scores. Delayed surgery is associated with a higher risk of complications, although the outcome is generally good. Associated AC joint dislocation found on postoperative radiographs does not influence outcomes. Shared decision making is key, and patients should be well aware of the potential risks and benefits of surgery.
