Surgical decompression and internal fixation of the injured spine have become standard procedures in the management of thoracic and lumbar spine fractures, but their effectiveness on neurological recovery remains controversial. We report on 169 consecutive patients with thoracic and lumbar spine fractures who were treated by reduction, fusion, and internal fixation using transpedicular screw-rod systems. Open decompression was carried out in 67 (39.6%) of them, including all 42 patients (25%) who presented with initial neurological deficits. At least 8 months following surgery, 30 (71%) had neurologically improved by one to three grades on the Frankel scale. Thirteen (59%) out of 22 patients whose initial deficits had been classified as "motor useless" (Frankel grades A to C) could walk, at least with support. Thirteen out of 20 patients with posttraumatic deficit Frankel D ("motor useful") improved to full recovery (Frankel E). In six (3.6%) patients (all from the group of the 127 patients without initial neurological deficits), permanent slight postoperative neurological impairment of one Frankel grade (E to D) was seen, among them two (1.2%) with new minor motor deficit. Neurological outcome was significantly better (p<0.01) in patients operated upon within the first 24 h after injury than in those who underwent surgery later. Severity of injury also had a negative influence (p<0.001) on neurological recovery. Analysis suggests that there may be significant neurological improvement in patients treated surgically very early.
During a 16 years'' period, a total of 79 dorsal root entry zone coagulations were performed in 68 patients for deafferentation pain. Of the 23 patients who underwent surgery for pain due to cervical root avulsion, 18 (82%) had a good (12) or fair (6) pain relief (mean follow-up period 51 months). Twelve (57%) patients with spinal cord injuries noted continuous pain reduction (10 good, 2 fair; mean follow-up 52 months). Continuous marked improvement for longer periods was reported only by 2 out of 10 patients with postherpetic neuralgia and 1 out of 7 patients with painful states due to other brachial plexus lesions and none out of 5 with spinal cord lesions (3) and phantom limb pain (2).
Vertical laminar fractures with dural tears and nerve root entrapment represent a special group of thoracic and lumbar spine injuries that carry a poor prognosis. However, special operative precautions lead to significant improvement in some of them although a majority remain unchanged or even worsened.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
