A retrospective analysis of the long-term outcomes of standard discectomy for lumbar disc herniation. ⋯ The long-term outcome of standard discectomy in this series was favorable. Although patients with preserved disc height generally had favorable results, the risk of recurrent disc herniation was high in this population.

A case report of anterior en bloc resected cervical intradural disc herniation and a review of the literature. ⋯ Cervical intradural disc herniation is an extremely rare condition. The pathogenesis remains obscure. Only 16 cases have been reported in the literature, and there has been little discussion concerning the local pathology of the herniated portion. The pathogenesis of the disease in the patient reported here was considered to be the adhesion and fragility of dura mater and posterior longitudinal ligament. This was caused by hypertrophy, with chronic inflammation and ossification of the posterior longitudinal ligament sustaining chronic mechanical irritation to the dura mater, leading to perforation of the herniated disc by an accidental force.

Comparative Study
Facet tropism: a comparison between far lateral and posterolateral lumbar disc herniations.
An assessment of the difference in the degree of facet tropism and disc degeneration between far lateral and posterolateral lumbar disc herniations. ⋯ This results suggest that the differences in the degree of facet tropism and disc degeneration might be considered a key factor in distinguishing the development of far lateral lumbar disc herniation from that of posterolateral lumbar disc herniation.

A case report of traumatic atlanto-occipital dislocation managed by transarticular screw fixation. ⋯ Anatomic reduction and reliable fixation with transarticular screws may provide satisfactory clinical results with important neurologic recovery in cases of atlanto-occipital dislocation.

The Medline and Embase databases containing randomized controlled trials of injection therapy published to 1998 were systematically reviewed. ⋯ Convincing evidence is lacking regarding the effects of injection therapy on low back pain. Additional well-designed explanatory trials in this field are needed.
