We analysed the influence of the timing of surgery (< 48 hours, group 1, 21 patients vs > 48 hours, group 2, 14 patients) on the neurological outcome and restoration of mobility in 35 incomplete tetra- and paraplegic patients with metastatic spinal-cord compression. Pain and neurological symptoms were assessed using the American Spinal Injury Association impairment scale. More improvement was found in group 1 than in group 2 when comparing the pre-operative findings with those both immediately post-operatively (p = 0.021) and those at follow-up at four to six weeks (p = 0.010). In group 1 the number of pre-operatively mobile patients increased from 17 (81%) to 19 patients (90%) whereas the number of mobile patients in group 2 changed from nine (64%) to ten (71%). These results suggest that early surgical treatment in patients with metastatic spinal-cord compression gives a better neurological outcome even in a palliative situation.

Outcome prediction after spinal cord injury (SCI) is essential for early counseling and orientation of the rehabilitative intervention. Moreover, prognostication of outcome is crucial to achieving meaningful stratification when conceiving clinical trials. Neurophysiological examinations are commonly employed for prognostication after SCI, but whether neurophysiology could improve the functional prognosis based on clinical predictors remains an open question. Data of 224 patients included in the European Multicenter Study about Spinal Cord Injury were analyzed with bootstrapping analysis and multivariate logistical regression to derive prediction models of complete functional recovery in the chronic stage after traumatic cervical SCI. Within 40 days after SCI, we evaluated age, gender, the motor and sensory cumulative scores of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), and neurophysiological variables (motor evoked potentials, sensory evoked potentials, nerve conduction study) as possible predictors. Positive outcome was defined by a Spinal Cord Independence Measure total score of 100. Analyzing clinical variables, we derived a prediction model based on the ISNCSCI total motor score and age: the area under the receiver operating curve (AUC) was 0.936 (95% confidence interval [CI]: 0.904-0.968). Adding neurophysiological variables to the model, the AUC increased significantly: 0.956 (95% CI: 0.930-0.982; p = 0.019). More patients could be correctly classified by adding the electrophysiological data. Our study demonstrates that neurophysiological assessment improves the prediction of functional prognosis after traumatic cervical SCI, and suggests the use of neurophysiology to optimize patient information, rehabilitation, and discharge planning and the design of future clinical trials.

Our clinical observation suggests that patients with spinal metastases and a high Tokuhashi score benefit from surgical treatment with moderate improvement in sensomotoric function even in a heterogenic collective.

BackgroundIn patients with myelomeningocele (MMC), a high number of fractures occur in the paralyzed extremities, affecting mobility and independence. The aims of this retrospective cross-sectional study are to determine the frequency of fractures in our patient cohort and to identify trends and risk factors relevant for such fractures.Materials and methodsBetween March 1988 and June 2005, 862 patients with MMC were treated at our hospital. The medical records, surgery reports, and X-rays from these patients were evaluated.ResultsDuring the study period, 11% of the patients (n = 92) suffered one or more fractures. Risk analysis showed that patients with MMC and thoracic-level paralysis had a sixfold higher risk of fracture compared with those with sacral-level paralysis. Femoral-neck z-scores measured by dual-energy X-ray absorptiometry (DEXA) differed significantly according to the level of neurological impairment, with lower z-scores in children with a higher level of lesion. Furthermore, the rate of epiphyseal separation increased noticeably after cast immobilization. Mainly patients who could walk relatively well were affected.ConclusionsPatients with thoracic-level paralysis represent a group with high fracture risk. According to these results, fracture and epiphyseal injury in patients with MMC should be treated by plaster immobilization. The duration of immobilization should be kept to a minimum (<4 weeks) because of increased risk of secondary fractures. Alternatively, patients with refractures can be treated by surgery, when nonoperative treatment has failed.
