Retrospective review. ⋯ Compared with custom-bent rods, unit rods provided superior correction of pelvic obliquity but were associated with higher transfusion requirements, higher infection rates, more proximal fixation problems, and longer intensive care unit and hospital stays.

Comparative Study
Computed tomography evaluation of rotation correction in adolescent idiopathic scoliosis: a comparison of an all pedicle screw construct versus a hook-rod system.
Retrospective review with historical cohort. ⋯ Our study finds axial rotation correction using APSs and a direct vertebral body derotation technique was significantly greater than that obtained with the HR construct.

Retrospective review. ⋯ Patients with scoliosis and OTRC have a greater risk of adding-on proximally and of loss of correction with anterior-only instrumentation; they may also have less predictable lumbar correction from selective thoracic fusion. However, after combined surgery, they have results similar to those of more skeletally mature patients.

Retrospective cohort study of consecutive patients undergoing primary fusion with segmental fixation for adult spinal deformity. ⋯ Using a strict definition of reoperation for a well-defined cohort, in the presence of relevant risk factors, many patients undergoing primary fusion for adult spinal deformity required reoperation. The results indicate that complex medical and surgical factors contribute to the treatment challenges posed by patients with adult spinal deformity. This represents the largest cohort reported to date of patients undergoing primary fusion using third-generation instrumentation techniques.

Outcomes of muscle-preserving interlaminar decompression (MILD) for the lumbar spine are reported. ⋯ In MILD for the lumbar spine, damage to the posterior stabilizing structures such as the intervertebral facet joints, paravertebral muscles, thoracolumbar fascia, supra- and interspinous ligaments, can be minimized, while preserving the function of the spinous processes as lever arms for lumbar extension.
