Analysis of 75 operated thoracolumbar fractures and fracture dislocations with and without neurological deficit.
Seventy-five surgically treated patients with thoracolumbar fractures and fracture dislocations, operated on between 1978 and 1982 at the Orthopedic Department of the University of Basel, were analyzed. The follow-up ranged from 18 months to 6 years. There were 45 men and 21 women, and 60% of the patients were not more than 30 years old. Additional injuries were common: 30% of the patients had craniocerebral injuries and 20% were polytraumatized. Ninety-six percent of all patients reached a hospital within 6 h, but only 23% initially presented at a center for spinal surgery. Sixteen patients had anterior surgery (fusion alone or with plating), and two of these had laminectomy as a second operation. Fifty-seven patients had posterior surgery, in 34 cases combined with a laminectomy. The Harrington instrumentation was used 45 times (29 distraction, 14 compression, and two combinations of distraction and compression rods). Luque rods with segmental sublaminar wiring was used seven times, the locking-hook distraction-rod system of Jacobs twice, and miscellaneous procedures five times. A total of 24 patients (greater than 30%) presenting neurological deficits improved postoperatively. None of the 18 patients with normal neurological findings deteriorated during the operation. Neurological improvement was seen more frequently after early than after delayed surgery, but the difference was not statistically significant. Laminectomy had no statistically significant effect on postoperative neurological status. Twenty-two patients required reoperation because of insufficient or failed instrumentation. Luque instrumentation had the highest rate of reoperations. Anterior surgery did not prove superior to posterior procedures. Hospitalization and immobilization time was significantly reduced with surgery for the neurologically normal or minimally damaged patients, but not for completely or incompletely paraplegic patients. Postoperative back pain occurred in 22 patients, of whom 14 had nonanatomic postoperative reductions. Complications directly due to the surgery were rare. It is our conclusion that the instrumentation used in this series was not good enough to be proposed for standardized use. These technically unsatisfactory results induced the development of the internal fixator system in the senior author's (E.M.) department.
