Thoracic spine fractures: injury profile and outcomes of a surgically treated cohort

摘要

There are only few reports in literature about the treatment of traumatic lesions of the thoracic spine. They have been grouped together with thoracolumbar fractures, ignoring the particular biomechanics of the thoracic segment. The objective of this retrospective cohort is to describe the clinical presentation and outcomes of surgically treated patients with these injuries. Data were obtained from the institutional database of medical registries, identifying all the patients who had been treated for thoracic spine fractures, from January 1, 1995 through December 31, 2005 in our institution. The study group included the 51 surgically treated patients. General and surgery-related complications were considered as clinical outcomes and injury-related disability was also assessed. Statistical analysis evaluating possible associations with timing and type of surgery, neurological impairment and associated injuries was carried out. Motor vehicle accident was the most frequent mechanism of injury. Six patients had an incomplete neurological deficit, whereas 22 had a complete lesion. Thirty-two patients presented at least one complication. Five of the neurologically intact patients, while 20 of those with neurological impairment presented general complications (p?=?0.0001). None of the patients’ neurological status deteriorated after surgery. All patients with complete spinal cord injury and those with incomplete cord injury with partial functional recovery received disability compensation. Short pedicle instrumentations should be used whenever possible, but also long instrumentations and mixed constructs may be necessary for the management of such unique fractures...
