Purpose: Scoliosis can be treated with vertebral body tethering (VBT) as a motion-sparing procedure. However, the knowledge of how growth is affected by a tether spanning multiple levels is unclear in the literature. Three-dimensional true spine length (3D-TSL) is a validated assessment technique that accounts for the shape of the spine in both the coronal and sagittal planes.

Purpose: Post-operative coronal decompensation (CD) continues to be a challenge in the treatment of adolescent idiopathic scoliosis (AIS). CD following selective spinal fusion has been studied. However, there is currently little information regarding CD following Vertebral Body Tethering (VBT).

Article Synopsis
  • This study reviews outcomes of thoracic anterior vertebral body tethering (AVBT) in patients with Lenke 1A vs 1C scoliosis curves after a minimum of 2 years.
  • Both groups showed similar thoracic curve correction but Lenke 1C had reduced correction of thoracolumbar/lumbar curves and better alignment at the lowest instrumented vertebra.
  • Overall, revision surgery rates were equivalent for both curve types, indicating that selective thoracic AVBT is effective for both Lenke 1A and 1C curves.

Study Design: IRB approved retrospective review of the the SHOnet (Shriners Health Outcomes Network).

Objectives: Osteogenesis imperfecta (OI) is the most prevalent genetic disorder of bone and connective tissue in the pediatric population, with an incidence of 1/15,000-20,000. Scoliosis has been reported to be present in 39-100% of OI patients and may continue to progress into adulthood but there is little information on the perioperative outcomes, rates of revision surgery and complications in this fragile population.

Purpose: The purpose of this study was to evaluate mid-term outcomes of magnetically controlled growing rods (MCGR), evaluate factors associated with unplanned return to the operating room (UPROR) vs achieving full length. Full length was defined as achieving > 85% of the elongating portion of the rod.

Methods: IRB approved retrospective single site study.

Study Design: Prospective comparative study.

Objectives: Evaluate the correlation of CXM with established measures of growth. Theoretically higher CXM levels would correlate with rapid longitudinal bone growth and lower levels with growth cessation.

Background: Although halo gravity traction (HGT) has been used to treat children with severe spinal deformity for decades, there is a distinct lack of high-quality evidence to speak to its merits or to dictate ideal manner of implementation. In addition, no guidelines exist to drive research or assist surgeons in their practice. The aim of this study was to establish best practice guidelines (BPG) using formal techniques of consensus building among a group of experienced pediatric spinal deformity surgeons to determine ideal indications and implementation of HGT for pediatric spinal deformity.

Study Design: IRB-approved retrospective single cohort study.

Objectives: To review our ten-year history with EDF (Elongation Derotation Flexion) casting in patients with infantile idiopathic scoliosis (IIS) to better understand which factors predict successful outcomes.

Summary Of Background Data: Numerous studies have demonstrated the efficacy of EDF casting in the treatment of progressive infantile idiopathic scoliosis.
