Randomized Controlled Trial Comparative StudyComparison between subcutaneous closed-suction drainage and conventional closed-suction drainage in adolescent idiopathic scoliosis patients undergoing posterior instrumented spinal fusion: a randomized control trial.
Prospective, randomized controlled clinical study. ⋯ The data suggest that subcutaneous closed-suction drainage offers a reasonable alternative to closed-wound suction drainage in adolescents idiopathic scoliosis patients undergoing posterior instrumented spinal fusion.

Comparative StudyWhat is the optimum fusion technique for adult isthmic spondylolisthesis--PLIF or PLF? A long-term prospective cohort comparison study.
Long-term prospective observational cohort study. ⋯ This study strongly supports the use of PLIF to obtain equivalent or superior clinical outcomes compared with PLF for spinal fusion for lumbar IS. Although there are considerable issues when commenting on the results of observational studies, the results of this study are the first to report long-term follow-up beyond 2 years, and further larger long-term randomized studies are suggested.

Case ReportsPosterior-approach vertebral replacement with rectangular parallelepiped cages (PAVREC) for the treatment of osteoporotic vertebral collapse with neurological deficits.
A retrospective clinical study. ⋯ PAVREC provided a satisfactory clinical and radiologic outcome without severe complications. This procedure can be a treatment option for osteoporotic vertebral collapse and an alternative to an anterior-approach or single posterior-approach reconstruction with a cylindrical cage.

Influencing segmental balance in isthmic spondylolisthesis using transforaminal lumbar interbody fusion.
Retrospective cohort study. ⋯ This study demonstrates that reduction of TS and restoration of disc space height are readily achieved with single-level TLIF. However, to establish an increase in SL consistent rod contouring and meticulous anterior placement of the interbody device should be applied. Excessive ventral positioning of the cages might result in insufficient disc space height restoration.

Do multilevel Ponte osteotomies in thoracic idiopathic scoliosis surgery improve curve correction and restore thoracic kyphosis?
To compare the routine use of posterior-based (Ponte) osteotomies to complete inferior facetectomies in thoracic idiopathic scoliosis. Hypokyphosis is common in thoracic adolescent idiopathic scoliosis. The use of pedicle screw fixation in deformity correction can exacerbate this hypokyphosis. We hypothesized that by utilizing posterior-based Ponte osteotomies rather than facetectomies, we could improve coronal plane correction and decrease the loss of kyphosis during curve correction. ⋯ This study shows a significantly higher blood loss and operative time associated with the use of routine posterior osteotomies in the thoracic spine without a significant improvement in coronal or sagittal correction.
