Abstract
BACKGROUND
The aim of this study was to compare the functional and radiological outcomes of unicortical vs bicortical fixation in patients with midshaft clavicular fractures who were treated using pre-contoured locking plates.
METHODS
We performed a prospective multicenter study of 45 individuals who underwent open reduction and internal fixation of midshaft clavicular fractures with precontoured locking plates between March 2017 and December 2019. Twenty-five patients were treated with bicortical screws and 20 patients with unicortical screws. Functional outcomes were assessed at 6 months and 12 months after surgery using the Constant score, the 11-item version of the Disabilities of Arm, Shoulder and Hand (Quick- DASH) score and the Single Assessment Numeric Evaluation (SANE) score. Pain was evaluated using a visual analog scale (VAS). The rate of return to work and sports was also recorded. Radiologic evaluation was obtained in the immediate postoperative day, monthly until fracture consolidation, at 6 months and 12 months. All intraoperative and postoperative complications were documented.
RESULTS
At both 6 and 12 months, the follow-up rates were 100%, and the mean age was 28.5 years (range, 20 to 45 years). The mean postoperative Constant score, Quick DASH, and SANE score at 12 months were 93.5 (±6), 2.3 (±3), and 92% (±7), respectively. There were no significant differences in the functional scores between the groups neither at 6 months nor at 12 months. Of the 30 active workers, 97% were able to return to their previous working routine and from the 25 patients who practiced sports before the injury,92% returned to sports all at the same level. All the fractures healed in both groups. There were 6 complications (13%).
CONCLUSION
In young, active patients with displaced midshaft clavicular fractures, both unicortical and bicortical locked plates achieved 100% bone consolidation, with excellent functional outcomes and a low rate of complications without significant differences between the groups. Therefore, locked plates with unicortical fixation could be a very good alternative for the management of young patients with midshaft clavicular fractures, potentially avoiding severe neurovascular complications.
