complications and challenges of sternoclavicular hook plates for treating sternoclavicular joint dislocations

Abstract objective This study aims to evaluate the efficacy and complications associated with the use of sternoclavicular hook plates for the treatment of traumatic sternoclavicular joint (SCJ) dislocations. Methods This study retrospectively analyzed the use of sternoclavicular (SC) hook plates for treating sternoclavicular joint (SCJ) dislocations, with a particular focus on identifying hardware-related complications such as plate breakages and fixation failures. A cohort of patients who underwent SC hook plate fixation was evaluated based on clinical outcomes, functional recovery, and the occurrence of complications. Data collection included postoperative imaging (X-rays and CT scans) to assess joint repositioning and hardware integrity, as well as functional assessments using the Constant Shoulder Score (CSS) and Visual Analog Scale (VAS) for pain. Results The utilization of hook plates led to successful joint stabilization and notable functional enhancement, as evidenced by the mean CSS scores increasing from 36.4 preoperatively to 86.6 postoperatively, and VAS scores decreasing from 7.2 to 1.6. However, 4 patients (8.7%) experienced plate breakages with no redislocation, and 1 patient (2%) encountered fixation failure necessitating revision surgeries. No major neurovascular complications were reported. Conclusions Despite providing effective stabilization for SCJ dislocations, sternoclavicular hook plates are associated with hardware-related issues, including plate breakages and fixation failures. Enhancements in implant design, surgical procedures, and patient selection are imperative in mitigating these concerns and enhancing long-term outcomes. Future research should prioritize the development of more robust implants and exploration of alternative treatment modalities.
