We reviewed the patterns of injuries sustained by 12 consecutive fallers and jumpers in whom primary impact was onto the feet. The fall heights ranged from 20 to 100 ft. The 12 patients sustained 49 significant injuries. Skeletal injuries were most frequent and included 15 lower extremity fractures, four pelvic fractures, and nine spinal fractures. In two patients, paraplegia resulted. Genitourinary tract injuries included bladder hematoma, renal artery transection, and renal contusion. Thoracic injuries included rib fractures, pneumothorax, and hemothorax. Secondary impact resulted in several craniofacial and upper extremity injuries. Chronic neurologic disability and prolonged morbidity were common. One patient died; the patient who fell 100 ft survived. After initial stabilization, survival is possible after falls or jumps from heights as great as 100 feet It is important to recognize the skeletal and internal organs at risk from high-magnitude vertical forces.

The pathogenesis of paraplegia after repair of thoracic aortic aneurysms is controversial. Using direct spinal cord evoked potential monitoring, critical intercostal arteries (CICA) were identified to evaluate the impact of backbleeding and ligation versus that of preservation during simulated aneurysm repair. Thirty pigs (40 kg) were randomly assigned to one of five groups. In groups 1 through 4, a thoracic segment containing CICA was cross-clamped for 60 minutes and distal aortic perfusion was provided by a centrifugal pump. In groups 1 and 2, the thoracic segment was vented, maintaining segment pressure at 0 mm Hg; CICA were ligated in group 1 and preserved in group 2. Thoracic segment was perfused at 70 mm Hg in groups 3 and 4; CICA were ligated in group 3 and preserved in group 4. Critical intercostal artery ligations were performed at the end of the cross-clamp period. In group 5 simple cross-clamping at the left subclavian artery was performed as a control. The combination of venting and ligation of CICA correlated with impaired neurologic outcome according to Tarlov's score (median, 1.5 in group 1 versus 3 in group 2; p = 0.015), indicated by a significant difference in median values of direct spinal cord evoked potential amplitude (expressed as a fraction of baseline values) at 120 minutes after cross-clamping (0.76 in group 1 versus 0.98 in group 2; p = 0.0082).(ABSTRACT TRUNCATED AT 250 WORDS)

The American Thoracic Society (ATS) has formulated guidelines for spirometry. We hypothesized that individuals with SCI (SCI), as a result of weak respiratory muscles, would exhibit poor test acceptability and reproducibility. Seventy-eight SCI subjects (39 with complete SCI) answered a respiratory questionnaire and performed spirometry. Of those with complete SCI, the proportion of subjects which met ATS criteria decreased with higher levels of injury. Poor test performance was not associated with age, respiratory symptoms or muscle fatigue. The most common reason for failing to meet ATS criteria for acceptability was excessive back extrapolated volumes (EBEV). Individuals with efforts that were acceptable except for EBEV and/or for exhalation of less than six seconds had values for forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) that were reproducible. If ATS criteria for acceptable spirometry were used in studying subjects with SCI, individuals producing otherwise reproducible values for FVC and FEV1 would be excluded. We found reproducibility similar to what has been reported in other cohorts and conclude that longitudinal study of respiratory function in SCI is feasible.

Compromise of the spinal canal and its neural elements is a well-recognized pathological entity affecting the lumbar or cervical spine. Thoracic stenosis in the absence of a generalized rheumatological, orthopedic, or metabolic disorder is rare. The authors report a case of progressive thoracic myelopathy leading to paraplegia following severe thoracic spinal stenosis secondary to post-traumatic hypertrophy of thoracic laminae and ossification of the ligamentum flavum and posterior longitudinal ligament.

A case of a thoracic meningioma presenting paraplegia 4.5 years after removal of a falx meningioma is reported. A 73-year-old woman, complaining of diplopia, was admitted to our department. Neurological examination revealed right abducens palsy. CT demonstrated a well-enhanced right frontal mass beneath the falx. The mass was totally removed under right frontal craniotomy. Its histology was transitional meningioma with rich fibroblasts. 4.5 years after craniotomy, she complained of progressing gait disturbance and nocturnal leg pain. Neurological examination revealed paraplegia, complete loss of leg sensation, loss of patellar and ankle reflex, bilateral positive Babinski reflex and urinary disturbance. Rectal function and anal reflex were preserved. Thoracic MRI demonstrated an intradural extramedullary mass which was well enhanced with Gd-DTPA at Th6-7. Under laminectomy, the mass was totally removed. Its histology was transitional meningioma with rich psammoma bodies and whirl formations. 4 months after removal, her palsy and sensory loss were almost completely recovered. We were able to find 15 cases of combined intracranial and spinal meningiomas in the literature. A young woman of neurofibromatosis suffered from tentorial, intraventricular and C1-2 meningiomas. Of 15 cases without neurofibromatosis including our case, 4 cases were of young boys and 11 cases were of women. Their initial symptoms originated from intracranial meningiomas in 8 cases. Multiple intracranial meningiomas were revealed in only 4 cases. In 9 cases, one case presented a combination of one intracranial meningioma and one spinal meningioma. Histology of intracranial meningioma was almost the same that of spinal meningioma in almost half of the 10 cases. These findings suggest the multi sentricity theory of multiple meningiomas originating in other neuroaxial compartments. Severe spinal dysfunction was recovered after removal in our case. Rectal function and anal reflex were preserved. These anorectal findings suggest that spinal dysfunction is either complete or incomplete. Motor evoked potentials are hopeful tools which can select reversible spinal motor dysfunctions.

BACKGROUND: The total transabdominal approach for thoracoabdominal aneurysm (TAA) was described in 1995 and it was suggested that outcome might be improved if the chest was not opened. This study reports early results of the technique with respect to operative morbidity and mortality rates for patients with abdominal aortic aneurysm extending to the diaphragm. METHODS: Between 1995 and 1998, 26 patients (median age 71 (range 52-84) years) underwent repair of a type IV TAA using a total abdominal approach and medial visceral rotation. RESULTS: Three patients presented with a contained leak. All survived but one developed paraplegia. Other complications included chest infection (five patients), myocardial infarction (three), reoperation for bleeding (three) and temporary dialysis in one patient. There were three perioperative deaths, two from myocardial infarction and one from multisystem organ failure. CONCLUSION: The total abdominal approach for the repair of type IV TAA is a reasonable alternative to a full thoracoabdominal incision. Thoracic complications are minimized, renal and visceral ischaemia times are low, and the perioperative mortality rate is acceptable.

Thoracic vascular trauma is divided into perforating and nonperforating injuries. Patients with perforating lesions with median sternotomy has to be performed if circulation is still functioning marginally. In a severe hemorrhagic shock it can be necessary to do an immediate emergency lateral thoracotomy. Trauma of the thoracic aorta occurs most frequently as a consequence of blunt injury as a result of decelerate or crushing. Fewer than 20% of patients with thoracic aortic injury survive the initial insult. Additionally the survival depends on severity of associated injuries. This means that the timing of surgical intervention in the stable, covered aortic rupture with serious associated injuries should preferably be deferred until the patients condition is stabilized. Emergency operation has to be performed in case of symptomatic transaction in the hemodynamic unstable condition including simultaneous surgery of concomitant lesions. Paraplegia remains the most deleterious problem. Endovascular stents are used increasingly to treat traumatic rupture of the aorta.

Thoracic epidural analgesia is a frequently utilised technique. Neurological complications are uncommon, but of grave consequence with significant morbidity. Spinal cord infarction following epidural anaesthesia is rare. We present a case where a hypertensive patient underwent an elective sigmoid colectomy under combined general/epidural anaesthesia for a suspected malignant abdominal mass. An epidural infusion was used for intra-operative and post-operative analgesia. During surgery, the blood pressure was labile and she was hypotensive. Postoperatively, the patient became confused, pyrexial and tachycardic and developed systemic inflammatory response syndrome requiring intensive care management. She developed a flaccid paralysis at L3 level with areflexia, analgesia and impaired sensation. A spinal cord infarct in the region of the conus extending into the thoracic cord was diagnosed. Complications of epidural anaesthesia are easily recognised when they develop immediately; their relationship to the anaesthesia and the post-operative period may be misjudged or underestimated when they appear after a delay, if neurological signs are masked by lack of patient cooperation and drowsiness or if the epidural anaesthesia is prolonged by long-acting drugs. New neurological deficits should be evaluated promptly to document the evolving neurological status and further testing or intervention should be arranged if appropriate. The association with epidural anaesthesia as a cause of paraplegia is reviewed. The aetiological factors that may have contributed to this tragic neurological complication are discussed.

A 63-year-old man visited our hospital in January 1993 because of back pain, which had been present for a year and persisted. The patient was diagnosed compression fracture of thoracic spine by another hospital. Thoracic plain radiographs revealed destructive and sclerotic changes with reduction of height of T 8, T 9 vertebral body. He had kyphosis on this level. Radiographs of the chest revealed hyperostosis of bilateral proximal clavicle. We diagnosed SAPHO syndrome (synovitis, acne, pustlosis, hyperostosis, and osteomyelitis: SAPHO) with T 8, T 9 spondylodiscitis, however without any skin manifestations. Oral indomethacin was effective, however thoracic kyphosis progressed gradually. Spastic gait and paraplegia appeared from February 1998, at last on July he was unable to walk independently. MRI showed the compression of spinal cord on T 8, T 9 level. We performed circumferential decompression and fusion with instrumentation. His paraplegia improved after surgery. We describe a rare case of SAPHO syndrome with paraplegia due to a thoracic kyphosis.

The objective is to present the possibility of an association between spinal epidural abscess and IgG deficiency. Spinal epidural abscess is a rare but potentially devastating condition. Review of the literature showed no reported acknowledgment about the relationship between spinal epidural abscess and IgG deficiency. This report discusses the case of a 16-year-old boy who developed progressive paraplegia within 24 hours. Clinical and neuroradiologic features are reported. Serum quantitative total IgG, IgA, and IgM concentrations were measured by nephelometry. Thoracic magnetic resonance imaging showed epidural abscess between T6 and T11 compressing the cord posteriorly. IgG subclasses (IgG ) were found abnormal. The possible importance of immunologic evaluation in the patients with spinal epidural abscess when no source of infection could be find is discussed.(4) (4) (4)
