To determine fusion necessity to one level below lower-end vertebra (LEV+1) in selective posterior fusion of moderate thoracolumbar/lumbar (TL/L) idiopathic scoliosis. ⋯ Our analysis almost showed no benefit for fusing to LEV+1 in moderate TL/L idiopathic scoliosis patients undergoing posterior selective fusion with pedicle screws. For patients with TL/L Cobb angle more than 60°, the distal fusion level probably needs to be LEV+1.

Comment on a case report on a challenging case of a severe spinal congenital deformity with a type I split spinal cord malformation (SSCM) in a 23-year-old with initial neurological symptoms. ⋯ In conclusion, despite a quite clear recommendation in the current literature to first surgically address the type 1 SSCM prior to correction of any spinal deformity, the authors of the present case chose to leave the bony spur. Still it remains to be seen if in this very case the spur will become clinically apparent in the future or not. As long as larger studies on curve correction without spur resection in SSCM are not available, spur resection prior to any type of curve correction remains the golden standard.

Disc cell therapies, in which cells are injected into the degenerate disc in order to regenerate the matrix and restore function, appear to be an attractive, minimally invasive method of treatment. Interest in this area has stimulated research into disc cell biology in particular. However, other important issues, some of which are discussed here, need to be considered if cell-based therapies are to be brought to the clinic. ⋯ If cell therapy for treatment of disc-related disorders is to enter the clinic as a routine treatment, investigations must examine the questions related to patient selection and the feasibility of achieving the desired repair in an acceptable time frame. Few diagnostic tests that examine whether cell therapies are likely to succeed are available at present, but definite exclusion criteria would be evidence of major disc fissures, or disturbance of nutrient pathways as measured by post-contrast MRI.
