Intra-operative spinal chord monitoring

Spinal surgery carries a small but definite risk of damaging the spinal chord. Early detection and correction of any reversible insult to the chord is important. An intra-operative 'wake-up' test has been used to monitor the chord function for more than 20 years. However, it has its limitations and disadvantages. Advances in electronics have facilitated the development and clinical application of electrophysiological methods in assessing the integrity of the spinal chord during surgery. It is now possible to monitor the spinal chord during surgery using various evoked potentials techniques.published_or_final_versio

Spinal cord compression secondary to brown tumour in a patient on long-term haemodialysis: a case report.

Brown tumours may occur secondary to hyperparathyroidism in patients with chronic renal failure (CRF). Diagnosing a spinal brown tumour causing cord compression requires a high index of suspicion. We report a 65-year-old woman, who had been on haemodialysis for CRF for over 10 years, who presented with leg weakness and back pain over the thoracolumbar junction. She had a brown tumour at T8 causing subacute spinal cord compression. Ambulation was regained after surgical decompression and stabilisation. Adherence to the National Kidney Foundation guidelines in the management of patients with CRF may prevent renal osteodystrophy. Treatment of spinal brown tumour depends on the severity of the neurological deficit. Remineralization is expected after correction of the parathyroid level, thus negating the need for total excision of the parathyroid glands.published_or_final_versio

The value of radiographs obtained during forced traction under general anaesthesia in predicting flexibility in idiopathic scoliosis with Cobb angles exceeding 60 degree

Our aim in this prospective radiological study was to determine whether the flexibility rate calculated from radiographs obtained during forced traction under general anaesthesia, was better than that of fulcrum-bending radiographs before corrective surgery in predicting the extent of the available correction in patients with idiopathic scoliosis. We evaluated 33 patients with a Cobb angle > 60 degrees on a standing posteroanterior radiograph, who had been treated by posterior correction. Pre-operative standing fulcrum-bending radiographs and those with forced-traction under general anaesthesia were obtained. Post-operative standing radiographs were taken after surgical correction. The mean forced-traction flexibility rate was 55% (SD 11.3) which was significantly higher than the mean fulcrum-bending flexibility rate of 32% (SD 16.1) (p 60 degrees in the standing position and may identify those patients for whom supplementary anterior surgery can be avoided.published_or_final_versio
