The causes of chronic diskogenic back pain have not yet been clearly identified. Neural ingrowth around the annulus is widely considered to be one of the possible cause. However, neuropathy around the annulus has yet to be observed visually. We report a case of a hotspot that was observed in an epiduroscopic view, but not in imaging findings. ⋯ In this study, we observed annulus hotspots, which have not been observed in imaging studies such as computed tomography or magnetic resonance imaging in patients with chronic back pain and leg pain, and observed remarkable symptom improvement after transforaminal epiduroscopic laser ablation.

Low bone mass in patients with adolescent idiopathic scoliosis has been well reported. Poor bone quality was regarded as a new and unique prognostic factor in aggravating curve progression. However, the potential biomechanical correlation between them remains unclear. ⋯ Biomechanical simulations indicated that low bone mineral mass might aggravate curve progression and induce more serious lumbar compensatory scoliosis in patients with adolescent idiopathic scoliosis. Weight gain was also a risk factor for curve progression.

Case Reports
High cervical spinal cord compression associated with anomaly of bilateral vertebral arteries.
Anomalies of the vertebral arteries are rare and usually detected incidentally. However, very rarely, they can manifest with clinical symptoms. We describe such a symptomatic case of high cervical spinal cord compression associated with persistent C2 segmental arteries. ⋯ Transposition of the vertebral artery by anchoring to the dura mater of the vertebral arch could be an effective and safe option for these disease conditions.

Severe traumatic brain injury (TBI) is a leading cause of death among children. Although several studies have reported the negative effects of concomitant injuries on mortality in adults with TBI, their effect on pediatric patients remains unclear. Our objective was to describe the effect of serious concomitant injuries on outcomes in pediatric patients with severe TBI. ⋯ Serious concomitant injuries are associated with higher mortality in pediatric patients with severe TBI, as a direct consequence, as well as due to concomitant injuries potentiating TBI pathobiology.
