A survey of vertebral burst-fracture management in Canada

In the management of burst fractures, the role of direct surgical removal of retropulsed bony fragments encroaching upon the spinal canal (direct decompression) is controversial. A questionnaire was mailed to 65 neurosurgeons and 36 orthopedic surgeons across Canada to determine the current management of vertebral burst fractures and the willingness of these surgeons to participate in a longitudinal study of the effects of direct surgical decompression in the management of burst fractures. Sixty-nine (44 neurologic and 25 orthopedic) surgeons responded to the questionnaire. Of those who responded, 97% of the neurologic surgeons and 95% of the orthopedic surgeons stated that they used plain radiography and computed tomography in their pretreatment investigations, and at least 50% in each specialty repeated these investigations at follow-up examinations. Standard tomography, magnetic resonance imaging and myelography were used less frequently both before and after surgery. There were no significant differences between specialties in the use of tests. Neurologic status and the treating surgeon's specialty were found to significantly influence management of burst fractures. According to 56% of neurologic surgeons and 81% of orthopedic surgeons, neurologically intact patients were usually treated with stabilization only (p less than 0.05). The greater number of neurosurgeons who used direct decompression was balanced by the number of orthopedic surgeons who used indirect decompression. Patients with partial, stable neurologic injuries were usually managed by direct decompression and stabilization according to 84% of the responding neurologic surgeons and 77% of the responding orthopedic surgeons.(ABSTRACT TRUNCATED AT 250 WORDS)
