Nerve-root anomalies are very uncommon, and there symptoms and signs are nearly similar with those of disc herniation. So we can misdiagnois them for intervertebral disc herniation. The negative Lasegue' sign is the only distinct feature of the nerve root anomalies. The authors report a case of Nerve-Root Anomaly associated with disc herniation in lumbar 4-5 interspace, which was diagnosed preoperatively in myelogram and confirmed surgically.

Intervertebral disc degeneration is main cause of various spinal degenerative conditions, and results in a significant socio-economic burden and morbidity to those affected. Intervertebral disc degeneration is a multifactorial process that has no known curative method. Hence, various factors that cause intervertebral disc degeneration, especially biochemical ones, were discussed in this study.

STUDY DESIGN: To study the correlation between the clinical outcomes and neovascularization and bFGF expression in the herniated disc tissues. OBJECTIVES: To study the difference of neovascularization and bFGF expression according to the types of disc herniation, and to study the correlation between the duration of radiculopathy, post-operative results and neovascularization and bFGF expression in the herniated disc tissues. SUMMARY OF LITERATURE REVIEW: Neovascularization has been found in herniated disc tissue. bFGF(basic Fibroblast Growth Factor) in the intervertebral disc has been implicated in the pathogenesis of injury and repair associated with granulation and neovascularization. There is no information on the relationship between clinical outcome and the neovascularization and bFGF expression in the herniated disc tissue. MATERIALS AND METHODS: Among 112 specimens, there are 48 cases in protrusion, 36 in extrusion and 28 in sequestration. Hematoxylin-eosin stain and immunochemical stain with CD 31 and bFGF were used. For the evaluation of post-operative results, Kirkaldy-Willis method was used. The results were analyzed with Chisquare test and t-test. RESULTS: Statistically there is no correlation between the types of disc herniation, duration of radiculopathy and post-operative outcomes and neovascularization and bFGF expression. CONCLUSIONS: The neovascularization and bFGF expression in herniated disc tissue are correlated with the injury of disc tissue. There are no correlation with the clinical outcomes and neovascularization and bFGF expression in herniated disc tissues.

Symptomatic thoracic disc herniation is an uncommon condition and early surgical approaches were associated with significant morbidity and even mortality. We are the first to describe the technique of percutaneous thoracic nucleoplasty in three patients with severe radicular pain due to thoracic disc herniation. Two of the patients experienced more than 75% pain relief and one patient experienced more than 50% pain relief. Post-procedural pain relief was maintained up to an average of 10 months after nucleoplasty. One patient with preoperative neurological signs improved postoperatively. There were no reported complications in all three patients. In view of the reduced morbidity and shorter operating time, thoracic intervertebral disc nucleoplasty can be considered in patients with pain due to thoracic disc herniation, with no calcification of the herniated disc, and in patients who may be otherwise be unfit for conventional surgery.
