Clinical Improvement Through Surgery for Adult Spinal Deformity: What Can Be Expected and Who Is Likely to Benefit Most?

Study Design: Multicenter, prospective, nonconsecutive, surgical case series from the International Spine Study Group.

Objectives: To evaluate the extent of clinical improvement after surgery for adult spinal deformity (ASD) based on minimal clinically important difference (MCID) and baseline measures.

Summary Of Background Data: For ASD, evaluation of surgical treatment success using clinical scores should take into account baseline disability and pain and the improvement defined relative to the MCID.

How the neck affects the back: changes in regional cervical sagittal alignment correlate to HRQOL improvement in adult thoracolumbar deformity patients at 2-year follow-up.

OBJECT Regional cervical sagittal alignment (C2-7 sagittal vertical axis [SVA]) has been shown to correlate with health-related quality of life (HRQOL). The study objective was to examine the relationship between cervical and thoracolumbar alignment parameters with HRQOL among patients with operative and nonoperative adult thoracolumbar deformity. METHODS This is a multicenter prospective data collection of consecutive patients with adult thoracolumbar spinal deformity.

Comparison of radiographic results after minimally invasive, hybrid, and open surgery for adult spinal deformity: a multicenter study of 184 patients.

Object: Various surgical approaches, including open, minimally invasive, and hybrid techniques, have gained momentum in the management of adult spinal deformity. However, few data exist on the radiographic outcomes of different surgical techniques. The objective of this study was to compare the radiographic and clinical outcomes of the surgical techniques used in the treatment of adult spinal deformity.

Radiographic Outcomes of Adult Spinal Deformity Correction: A Critical Analysis of Variability and Failures Across Deformity Patterns.

Study Design: Multicenter, prospective, consecutive, surgical case series from the International Spine Study Group.

Objectives: To evaluate the effectiveness of surgical treatment in restoring spinopelvic (SP) alignment.

Summary Of Background Data: Pain and disability in the setting of adult spinal deformity have been correlated with global coronal alignment (GCA), sagittal vertical axis (SVA), pelvic incidence/lumbar lordosis mismatch (PI-LL), and pelvic tilt (PT).

Effect of spine fellow training on operative outcomes, affirming graduated responsibility.

Study Design: Retrospective review of prospectively collected surgical data.

Objective: This study sought to determine the effect of fellow education during the course of the academic year (August-July) on surgical outcomes in adolescent idiopathic scoliosis. One surgeon and one type of surgery were chosen to minimize confounding factors.

Effect of spinal deformity on adolescent quality of life: comparison of operative scheuermann kyphosis, adolescent idiopathic scoliosis, and normal controls.

Study Design: A prospective multicenter study and retrospective chart review.

Objective: To compare health-related quality of life (HRQOL) measures and sagittal deformity in operative Scheuermann kyphosis (SK), operative adolescent idiopathic scoliosis (AIS), and normal populations.

Summary Of Background Data: No study to date has evaluated patient reported HRQOL measures before surgery in operative patients with SK.
