Case ReportsPosterior Surgery for Adolescent Idiopathic Scoliosis With Pedicle Screws and Ultra-high Molecular Weight Polyethylene Tape: Achieving the Ideal Thoracic Kyphosis.
Prospective clinical case series. ⋯ The correction of deformity with PSTH-DVR is equivalent to that of all-pedicle screw constructs. The procedure gives favorable correction, is advantageous for kyphosis compared with segmental screw fixation, and uses the minimum number of pedicle screws. Therefore, the PSTH-DVR procedure may be useful for treatment of idiopathic scoliosis.

Risk Factors for Proximal Junctional Kyphosis Associated with Dual-Rod Growing-Rod Surgery for Early-Onset Scoliosis.
A retrospective, multicenter study. ⋯ The significant independent risk factors for PJK during dual-rod GR treatment for EOS were a lower instrumented vertebra at or cranial to L3, a proximal thoracic scoliosis of ≥40 degrees, and a main thoracic kyphosis of ≥60 degrees.

Using a Combination of Intralaminar and Pedicular Screw Constructs for Enhancement of Spinal Stability and Maintenance of Correction in Patients With Sagittal Imbalance: Clinical Applications and Finite Element Analysis.
Case series and finite element analysis. ⋯ Addition of an ILS construct to PS construct decreases osteotomy line deformation and reduces stress on pedicle fixation points, and the combination improves fixation stability over the conventional PS-rod technique.

Detection of Pseudarthrosis in Adult Spinal Deformity: The Use of Health-related Quality-of-life Outcomes to Predict Pseudarthrosis.
Single-center, retrospective study of consecutive surgeries. ⋯ Standard radiographs are insufficient for identifying PSAR in adult spinal deformity patients. Failure to achieve significant improvement in SRS and ODI should lead the surgeon to suspect PSAR and consider additional investigation.

Associations between Body Mass and Revision Surgical Outcomes in Adult Scoliosis.
Retrospective cohort study. ⋯ Overweight revision adult scoliosis patients had higher thoracic kyphosis and more significant preoperative pain compared with normal-weight individuals. Overweight patients also had significantly higher rates of medical comorbidities. However, BMI did not affect the functional outcome of surgical correction or perioperative complication rates. Overweight patients benefited from surgery just as much as nonoverweight patients at 2-year follow-up.
