Appropriate surgical management of spinal metastases combines maximal neural decompression with simultaneous immediate spinal column stabilization in the context of a paliative operation undertaken to improve patients' quality of life. We have used a single-stage posterolateral vertebrectomy (SPLV) for disease of the lumbar spine, combined with bilateral costotransversectomies in the thoracic spine, for these challenging cases. In this prospective cohort study of 96 consecutive patients with metastatic disease of the spinal column for we describe our surgical technique in detail, we examine our learning curve in its use and we analyze the long-term surgical and "quality of life" results in 42 patients who underwent SPLV. The mean and maximum operative blood loss was significantly lower for the SPLV group when compared with combined approaches. All patients either remained neurologically stable or had improved with surgery. Both the mean and the range visual analog scale scores were significantly improved after the SPLV. The SPLV was the only surgical approach to demonstrate a statistically significant improvement in Eastern Cooperative Oncology Group scores at 3 months after the surgery. Seventy-five percent of patients were alive at 6 months and 50% of patients survived for more than 12 months after the surgery. Eleven patients had a major complication (26%) with 9 (21%) patients required early reoperation, 7 of them for wound failure. Our data demonstrates that the SPLV represents a technically achievable improvement in surgical approach to spinal metastases when key parameters are examined. On the basis of these results, we recommend that the SPLV should be considered in all cases where resection of thoracic or lumbar spinal metastatic disease and reconstruction is contemplated.

The study is a prospective blinded randomised controlled trial to compare the efficacy of triamcinolone acetonide, bupivacaine or in combination in managing pain after lumbar discectomy. Patients undergoing primary single-level lumbar discectomy were randomised. Triamcinolone acetonide, bupivacaine or in combination was instilled at the nerve root as decompression. Preoperative, day 1 and 6 weeks pain score, 24-h postoperative opiate requirements and duration of inpatient stay were recorded. Data was analysed using Mann-Whitney test for statistical significance. 100 patients were recruited. A significant difference was noted in day one postoperative mean pain score, mean 24-h opiate requirement and mean inpatient stay in the triamcinolone acetonide and bupivacaine group. At 8 weeks postoperatively, no significant differences were seen in the pain score in all groups. Significant postoperative pain reduction and opiate requirements in the first 24 h, and significantly shortened duration of inpatient stay were achieved in the triamcinolone acetonide and bupivacaine group compared with other groups.

Ganglia of the knee joint are rare and are mostly an incidental finding during arthroscopy or MRI examinations. Usually their origin is intraarticular, arising from the menisci or ACL or PCL. Ganglia arising from the infrapatellar fat pad are rare and only few are mentioned in the literature. We report a case of infrapattellar ganglion in a 41-year-old female, which developed from the infrapattellar fad pad and with minimal intraarticular extension.

We present a case of progressive atlanto-occipital dislocation, recognized by a new onset of positive neurologic findings. We discuss the anatomic relationship of the lower four cranial nerves to the foramen magnum and the atlanto-occipital joint. The importance of careful assessment of the cranial nerves prior to choosing a treatment algorithm is emphasized.
