Segmental spinal instrumentation for neuromuscular spinal deformity

Seventy-six consecutive surgical cases of paralytic neuromuscular spinal deformity were retrospectively analyzed. Posterior arthrodesis with segmental spinal stabilization with Luque L-rods, sometimes preceded by anterior release, was done in all cases. The infection rate of 14.5% was observed to be markedly higher in patients with myelodysplasia. Deep placement of the rods lateral to the spine and well beneath full-thickness skin is recommended to reduce the incidence of this complication.     

Intra-operative spinal sonography in spinal intramedullary tumor

Recently, operative results of intramedullary spinal cord tumors have been greatly improved since the introduction of microsurgery. It is very important to know the precise size and location of the tumor prior to the operation so that we can approach the tumor with a minimum of damage to the spinal cord. However, it is not always possible to demonstrate the precise localization of the tumor preoperatively. In this report, we emphasize that intraoperative spinal sonography is very useful in determining the extent of the tumor and differentiating solid component from cystic component of the tumor. Methods and Materials We performed intraoperative spinal sonography on ten patients with intramedullary spinal cord tumor. This series included three cases of hemangioblastoma, three cases of astrocytoma, two cases of ependymoma, one case of subependymoma, and one case of mixed glioma. Eight out of ten cases were associated with cysts. The intraoperative spinal sonographic examinations were performed after laminectomy. The linear scanning probe of 5 or 7.5 MHz transducer was used. Results 1) Solid components The acoustic pattern of the solid tumor was either hyperechoic or iso-echoic. Six cases (three hemangioblastomas, two ependymomas, and one astrocytoma) were hyperechoic. Other four cases (two astrocytomas, one subependymoma, and one mixed glioma) were iso-echoic. 2) Cystic components The cysts associated with the tumor were anechoic in six out of eight cases, which were confirmed at surgery, and multiple cysts were identified.(ABSTRACT TRUNCATED AT 250 WORDS)     

Rationale for spinal fusion in lumbar spinal stenosis

In order to define the indications for spinal fusion in patients undergoing decompression for lumbar spinal stenosis, 114 patients surgically treated were reviewed. Follow-up was 24 to 108 months. Patients were grouped into four categories: 15 with lateral recess stenosis, 45 with central-mixed stenosis, 43 with stenosis following prior lumbar surgery(s), and 11 with scoliosis and spinal stenosis. Only two patients with lateral recess stenosis underwent fusion with fair results. Approximately one-third of those with central-mixed stenosis required a fusion. Results were good in 70%. In those with stenosis following prior lumbar surgeries, although not statistically significant, those who had concomitant decompression and arthrodesis had a better outcome than those in whom decompression only was done. Patients with scoliosis and stenosis had decompression for significant motor and reflex deficits and fusion over the length of their major curves. Patients having decompression for lumbar stenosis with degenerative spondylolisthesis, isolated disc resorption with degenerative facet joints, intervertebral disc disease with instability, and those with scoliosis with multidirectional instabilities benefit from concomitant spinal fusion.
