Safety and feasibility of rigid fixation by SternaLock Blu plates during the modified Ravitch procedure: a pilot study

Delayed presentation of manubriosternal dislocation after thoracolumbar spondylodesis in a polytrauma patient - a case report

BACKGROUND

Manubriosternal dislocations are a rare entity and frequently associated with thoracic spine fractures and, in minority of cases, with cervical or thoracolumbar fractures.

METHODS

Our case represents a 38-year-old male who fell from a height resulting in multiple fractures, amongst others of the first lumbar vertebra. At primary survey and computed tomography scan no manubriosternal injury was apparent. After posterior stabilization of the thoracolumbar vertebrae a manubriosternal dislocation was identified and stabilized using plate-and-screw fixation.

RESULTS

Clinical findings of a manubriosternal dislocation are not always obvious, allowing them to be missed at initial assessment.

CONCLUSIONS

Manubriosternal dislocations can be missed at the initial investigation, even on cross-sectional imaging, and only become visible after spine stabilization because of the tight relationship between sternum and vertebrae in the thoracic cage. There is no unanimity in literature for surgical treatment of manubriosternal dislocations, although plate fixation is generally considered a safe and effective treatment option.
