Case report. ⋯ By using surgical resection and hematoma evacuation, good outcome could be achieved for spinal osteoblastoma complicated with epidural hematoma.

A coculture of synovium-derived stem cells (SDSCs) and nucleus pulposus cells (NPCs) in a serum-free pellet system was treated with varying doses of transforming growth factor beta (TGF-beta). Cultures of either SDSCs or NPCs alone served as controls. ⋯ SDSCs may act as a potential mesenchymal stem cell candidate for NP regeneration. Further studies are needed to evaluate the in vivo effect of SDSCs on disc regeneration.

Randomized Controlled Trial
What works best for whom? An exploratory, subgroup analysis in a randomized, controlled trial on the effectiveness of a workplace intervention in low back pain patients on return to work.
Exploratory subgroup analysis in a randomized controlled trial (RCT). ⋯ The findings from these exploratory analyses should be tested in future RCTs. This workplace intervention seems very suitable for return to work of older workers and workers with previous sick leave. Gender, perceived heavy work, and baseline scores in pain and functional status should not be a basis for assignment to this intervention.

Case report. ⋯ When a conventional transforaminal PELD is impossible due to the presence of a high iliac crest, PELD via a transiliac route could be a alternative option in selected cases.

Comparative Study
Computer navigation in balloon kyphoplasty reduces the intraoperative radiation exposure.
Comparison of the dose area product (DAP), the radiation time and the operation time during computer navigated and conventional balloon kyphoplasty procedures. ⋯ The use of computer navigation systems in balloon kyphoplasty procedures reduces the radiation exposure of patients and surgeons significantly. The increased technical effort did not lead to a significant longer operation time. Hence, the use of computer navigation systems in balloon kyphoplasty procedures is recommended.
