The comprehensive anatomical spinal osteotomy classification.

Background: Global sagittal malalignment is significantly correlated with health-related quality-of-life scores in the setting of spinal deformity. In order to address rigid deformity patterns, the use of spinal osteotomies has seen a substantial increase. Unfortunately, variations of established techniques and hybrid combinations of osteotomies have made comparisons of outcomes difficult.

The impact of a corrective tether on a scoliosis porcine model: a detailed 3D analysis with a 20 weeks follow-up.

Purpose: Non-fusion treatment for adolescent idiopathic scoliosis generates interest due to the potential for growth preservation and mobility. Using an established porcine scoliotic model, this study aims to evaluate the global alignment and the morphology of the spine with and without application of a non-fusion corrective tether.

Methods: At 12 weeks of age, 21 immature Yorkshire pigs had an induction of scoliosis.

Assessment of symptomatic rod fracture after posterior instrumented fusion for adult spinal deformity.

Background: Improved understanding of rod fracture (RF) in adult spinal deformity could be valuable for implant design, surgical planning, and patient counseling.

Objective: To evaluate symptomatic RF after posterior instrumented fusion for adult spinal deformity.

Methods: A multicenter, retrospective review of RF in adult spinal deformity was performed.

Sacro-femoral-pubic angle: a coronal parameter to estimate pelvic tilt.

Introduction: Pelvic tilt is an established measure of position which has been tied to sagittal plane spinal deformity. Increased tilt is noted in the setting of the aging spine and sagittal malalignment syndromes such as flatback (compensatory mechanism). However, the femoral heads are often poorly visualized on sagittal films of scoliosis series in adults, limiting the ability to determine pelvic incidence and tilt.
