Abstract

Objective: This study evaluates the efficacy and complications associated with sternoclavicular(SC)hook plates in treating traumatic sternoclavicular joint (SCJ) dislocations. Methods: A retrospectively analyzed on patients who underwent SC hook plates forfixation SCJ dislocations, focusing on hardware-related complications such as plate breakages and fixation failures. Clinical outcomes, functional recovery, and complications were assessed. Postoperative imaging, including X-raysand CT scans, was used to evaluate joint reduction and hardware integrity, Functional out comes were measured using the Constant Shoulder Score (CSS) and Visual Analog Scale (VAS) for pain. Results: SC hook plates effectively stabilized the joint and significantly improved function, as demonstrated by an increase in the mean CSS scores from 36.4 preoperatively to 86.6 postoperatively, and a decrease in VAS scores from 7.2 to 1.6. However, 4 patients (8.7%) experienced plate breakages without redislocation, and 1 patient (2%) experienced fixation failure, requiring revision surgeries. No major neurovascular complications were observed. Conclusions: While SC hook plates provide effective stabilization for SCJ dislocations, they are associated with hardware-related complications, including plate breakages and fixation failures. Improvements in implant design, patient selection are necessary to address these issues and improve long-term outcomes. Future research should focus on the developing of more ergonomic implants and exploration of alternative treatment options.
