摘要:

Cervical spine injuries associated with three-point fixation lap-sash seat belts result from Impact against the sash. While such injuries are infrequent and often without serious neurologic sequelae, they may produce serious deficits with grave injuries. Flexion-extension fractures of the lower cervical vertebrae, fractures of the transverse and spinous processes of the lower cervical and uppermost thoracic vertebrae, discal disruptions, and brachial plexus avulsions may occur. Of the 3 patients reported here, 2 escaped serious damage.

摘要:

Two cases of vertebral osteomyelitis and discitis in the cervical spine are presented, both having arisen from hematogenous spread to the spine. Bacteriologic diagnosis was established in 1 patient, but the infection had subsided in the other. Both patients were treated with anterior debridement and fusion, and a supplemental posterior wiring and fusion was performed in the second case to reduce kyphotic anguiation. In the second case, both the anterior and posterior surgery were performed while the patient was under the same anesthetic. Satisfactory results were achieved in both cases.

摘要:

Involvement of the spine by Chondrosarcoma is rare. Three recent cases involving the cervical with or without extension to the thoracic spine are reported. Detailed radiologic investigations to evaluate the extent of the disease are essential to management. Computerized axial tomography and anglography were performed in 1 case and were extremely helpful. Surgical resection of the lesion is the only currently effective method of treatment, but long-term survival figures are not good.

摘要:

A case of ventral extradural cervical defect produced by extension during myelography is reported. The defect simulated a herniated cervical disc. This phenomenon has been reported in the lumbar area, but not in the cervical region. The etiology is discussed.

摘要:

Efforts are made to quantitate the tension exerted on a portion of the titanium cable used during the Dwyer instrumentation procedure for scollosis. An inductively-powered biotelemetry unit contained within a load cell positioned on the cable so as not to alter its clinical use has been developed. Six implants have been tested both in vitro over the range of anticipated forces on the cable andin vivofollowing insertion of the device in conjunction with Dwyer instrumentations in 6 dogs. The tension on the cable has been monitored from the intraoperative period to time of sacrifice at 12 months postsurgery. The study shows that merely tightening the cable to the level shown on the tensioner does not always accurately reflect the actual load being placed on the titanium cable. A marked decrease in tension is noted immediately upon crimping the screws. Stressing of the anesthetized dogs during the first few weeks following surgery shows markedly increased levels of tension. The similar procedure performed from 8 to 12 months after surgery at a time when spinal fusion is well advanced indicates virtually no change in the tension. It is hoped that the telemetric transducer will serve as an independent and perhaps earlier indicator of spinal fusion to allow for better postoperative management.

摘要:

The deforming mechanisms in the congenital lumbar kyphosis of myelomeningocele are situated anteriorly. Posterior wedge resection with local fusion therefore will not prevent progression of the deformity. Nonetheless, this procedure may be the only method of affording sac closure, or providing continuity of the ulcerated integument. Definitive corrective surgery will be required later and must combat the anterior deforming forces. Resection of the apical vertebral body followed by posterior fusion with Harrington instrumentation provides a solid straight spine

摘要:

This report contains a case presentation of monozygotic twins who had concordant right thoracic scoliosis of differing severities. One twin also had an associated congenital left lumbar scoliosis and urologic abnormalities. This report would suggest that the genetic basis of scoliosis may occur at multiple gene loci.

摘要:

A case of hereditary multiple exostoses (HME) with compression of the cervical cord, the cervical plexus, and the ulnar nerve is reported. Complete recovery following surgery was obtained. Review of the literature revealed 21 previous cases of HME with cord compression. The cervical and thoracic areas are predominantly affected and the symptoms usually evolve slowly. Recovery after laminectomy is to be expected in the majority of the cases.

摘要:

Five hundred consecutive idiopathic scoliosis patients in whom routine oblique roentgenograms of the lumbosacral area were obtained, plus 39 patients with a presenting problem of spondylolisthesis, were reviewed in an attempt to answer questions concerning the best therapeutic approaches in patients having coincident scoliosis and pars defects. The incidence of pars defects in patients with idiopathic scoliosis was found to be 6.2%, slightly higher than in the white female population at large. The indications for a surgical approach to the pars defect and/or the spinal curvature parallel the indications for each problem arising independently.

摘要:

The purpose of this presentation is to outline the extent of surgical resection necessary for complete decompression of the neural elements in spinal stenosis and to introduce a system for the evaluation of disability in patients with spinal stenosis. Sixteen patients with the confirmed diagnosis of lumbar spinal stenosis were evaluated by the system. Ten cases were treated surgically. Indications for operative treatment were 1) intolerable pain in average daily living, 2) progressively worsening or significant degree of motor weakness, and 3) sphincter dysfunction. Satisfactory results from operative treatment were expected only after adequate and thorough decompression. The extent of surgical decompression was determined by clinical evaluation, myelographic examination, and by the type of disease process exhibited. The most common cause of unsatisfactory results was inadequate decompression of spinal contents. The extent of adequate decompression is described according to three different variations of pathologic anatomy of spinal stenosis: a) concentric contraction of the spinal canal, b) sagittal flattening of the spinal canal, and c) stenosis caused by anomalous articular process(es). No excellent results were obtained even after thorough and adequate decompression of spinal contents.
