Comparative Study
Comparison of bone grafts for posterior spinal fusion in adolescent idiopathic scoliosis.
A retrospective comparison of three different types of bone grafts for posterior spinal fusion in adolescent idiopathic scoliosis. ⋯ Fusion rates were comparable for GroupA (ICBG) and Group C (composite graft of autologous bone marrow and demineralized bone matrix). The composite graft is our preferred graft for fusions in adolescent idiopathic scoliosis.

A new surgical technique for en bloc resection of posterior mediastinum tumors invading the spine is described. ⋯ Even though a learning curve is necessary to achieve this extreme type of surgery, selective preoperative screening of patients is mandatory. Interesting results today confirm the feasibility of possible treatment of tumors still considered unresectable.

Comparative Study
Pedicle morphology of the lower thoracic, lumbar, and S1 vertebrae: an Indian perspective.
Analysis of morphometric data obtained from computed tomography scans in relation to the lower thoracic, lumbar, and S1 pedicle in patients from the Indian subcontinent. ⋯ Significant differences exist between the pedicles of Indian and white populations. It is suggested that preoperative computed tomography scans of the patients must be evaluated to choose the appropriately sized implant and avoid inadvertent complications. Preparation of the pedicle intraoperatively should take into account the orientation of the transverse pedicle angle.

A reliability study was performed. ⋯ The ODI was highly reliable. The questions about work, back satisfaction, and pain medication showed good agreement. The GFS, pain intensity, fear-avoidance beliefs, and life satisfaction appeared to lack sufficient reliability to be recommended in postal questionnaires.
