STUDY DESIGN: Single-center retrospective analysis of consecutive patients who have undergone circumferential minimally invasive surgery (cMIS) for correction of adult spinal deformity (ASD). OBJECTIVES: To study the rates of reoperations and readmissions within the first 30 days following cMIS for correction of ASD. BACKGROUND: Hospital readmission and reoperation rates have been emphasized as an important measure of quality and cost-effectiveness of care...

BACKGROUND: Congenital gibbus deformity of the spine associated with myelodysplasia is a challenging problem in the growing child and is commonly associated with skin breakdown and chronic infection. Surgical solutions including kyphectomy, flap closure of the skin, and early spinal fusion are associated with a high rate of complications and, ultimately, a short trunk due to stoppage of spinal growth. The purpose of this article is to describe our early results in using a rib-based distraction to the pelvis without vertebral resection and fusion to manage this deformity...

BACKGROUND: Rod fracture is a common complication of growing rods and can result in loss of correction, patient discomfort, and unplanned revision surgery. The ability to quantitate rod integrity at each lengthening would be advantageous to avoid this complication. We investigate the feasibility of applying structural health monitoring to evaluate the integrity of growing rods in vitro. METHODS: Single-rod titanium 4.5-mm growing rod constructs (n = 9), one screw proximally and one distally connected by in-line connectors, were assembled with pedicle screws fixed in polyethylene blocks...

STUDY DESIGN: Retrospective review. OBJECTIVES: To describe clinical characteristics and infection rates in modern vertical expandable prosthetic titanium rib (VEPTR) surgery. SUMMARY OF BACKGROUND DATA: Prior studies have demonstrated infection rates from 10% to 30% with VEPTR surgery. METHODS: A retrospective query was done on an institutional review board-approved, multicenter prospectively collected database for patients implanted with VEPTR from 2007 to 2013 at eight sites...

STUDY DESIGN: Retrospective consecutive case series. OBJECTIVES: To estimate the amount of ionizing radiation (IR) exposure in growing rod (GR) surgery for early-onset scoliosis. SUMMARY OF BACKGROUND DATA: There is substantial evidence of the health hazards attributed to IR exposure. However, no studies have estimated the amount of IR exposure in GR surgery. MATERIALS AND METHODS: A consecutive single-center series of GR patients were retrospectively reviewed...

OBJECTIVES: The purpose of this study was to determine the cost/quality-adjusted life-year (QALY) of the operative treatment of lumbar spondylolisthesis and identify factors associated with cost-effectiveness at 2 years. METHODS: We evaluated patients who underwent surgery for spondylolisthesis. The QALY was determined from the EQ5D. Outcomes were also assessed using the Oswestry Disability Index (ODI). Surgical, neuromonitoring, and anesthesia Current Procedural Terminology (CPT) codes as well as hospital Diagnosis-Related Group codes were used to determine the Medicare direct care costs of surgery...

STUDY DESIGN: Prospective observational study. OBJECTIVE: To evaluate the effect of internal thoracoplasty and anterior spine release combined with posterior spinal instrumentation in correcting and preventing a reoccurrence of the rib cage deformity in adolescent idiopathic thoracic scoliosis >70 degrees. SUMMARY OF BACKGROUND DATA: The rib cage deformity rather than the lateral curvature of the spine is usually the major cosmetic deformity in severe adolescent idiopathic thoracic scoliosis...

STUDY DESIGN: Retrospective case series. OBJECTIVES: To compare radiographic and clinical outcomes in posterior spine fusions with pedicle screw instrumentation of varying screw densities in the treatment of adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Posterior spinal fusion with pedicle screw instrumentation is the mainstay of surgical treatment for AIS. The most commonly used construct consists of screws placed at every level on the concave side of the deformity and nearly every level on the convex side...

STUDY DESIGN: Biomechanical analysis. OBJECTIVES: To show the role of additional rods and long-term fatigue strength to prevent the instrumentation failure on three-column osteotomies. SUMMARY OF BACKGROUND DATA: Three-column osteotomy such as pedicle subtraction osteotomy (PSO) and vertebral column resections are surgical correction options for fixed spinal deformity. Posterior fixation for the PSO involves pedicle screw-and rod-based instrumentation, with the rods being contoured to accommodate the accentuated lordosis...

STUDY DESIGN: This study determines the rate of change in the scoliosis surgery plan in cases presented in preoperative indications conference. OBJECTIVES: To determine the effect of preoperative indications conference on the plan of surgery and to identify characteristics that increased the likelihood of change. SUMMARY OF BACKGROUND DATA: Preoperative indications conferences are used as a teaching and planning tool. Levels of fusion, construct options, and necessity for osteotomies are often debated in the planning of scoliosis surgery...

STUDY DESIGN: Comparing thoracic pedicle screw trajectories, screw lengths, and starting points by examining osteologic specimens. OBJECTIVE: Describe a medial screw trajectory (MST) compared to a screw trajectory along the anatomic pedicle angle (APA) in terms of trajectory, screw length, and starting point. SUMMARY OF BACKGROUND DATA: Although thoracic pedicle screw insertion is commonly used for posterior fusion and instrumentation, there is little data to quantify an MST that avoids the great vessels and allows for greater screw purchase...

STUDY DESIGN: Cross-sectional Objectives: To present a reliable and valid Danish translation of the Scoliosis Research Society-22R (SRS-22R). SUMMARY OF BACKGROUND DATA: The SRS22R was designed as a disease-specific measure of quality of life in surgically treated adolescent idiopathic scoliosis (AIS) patients. It has been translated and adapted into several languages. A reliable and valid Danish version is not available. METHODS: A Danish version of the SRS-22R was developed using previously published and widely accepted guidelines...

STUDY DESIGN: Biomechanical cadaveric study. OBJECTIVE: To compare the biomechanical properties of the iliac and S2-Alar-Iliac (S2AI) screw in a similar spinopelvic fixation construct. SUMMARY OF BACKGROUND DATA: Spinopelvic fixation is used in the correction of pelvic obliquity, high-grade spondylolisthesis, and long spinal fusions. With the development of pedicle screw fixation, the iliac screw has been used as an anchor point to the pelvis...

STUDY DESIGN: A hypothesis-driven study was conducted in a familial cohort to determine the potential association between variants within the TBX6 gene and Familial Idiopathic Scoliosis (FIS). OBJECTIVE: To determine if variants within exons of the TBX6 gene segregate with the FIS phenotype within a sample of families with FIS. SUMMARY OF BACKGROUND DATA: Idiopathic Scoliosis (IS) is a structural curvature of the spine whose underlying genetic etiology has not been established...

STUDY DESIGN: To test for rare genetic mutations, a cohort of patients with unexplained early onset scoliosis (EOS) was screened using high-density microarray genotyping. A cohort of patients with adolescent idiopathic scoliosis (AIS) was similarly screened, and the results were compared. SUMMARY OF BACKGROUND DATA: Patients with scoliosis in infancy or early childhood (EOS) are at high risk for progressive deformity and associated problems including respiratory compromise...

STUDY DESIGN: Comparison of disc tissue from rat tails in six groups having different mechanical conditions imposed. OBJECTIVES: To identify disc annulus changes associated with the supposed altered biomechanical environment in a spine with scoliosis deformity using an immature rat model that produces disc narrowing and wedging. BACKGROUND: Intervertebral discs become wedged and narrowed in a scoliosis curve, probably due in part to altered biomechanical environment...
