“…8 Ultimately, research based on the staple led to further advances, and current investigations into a vertebral body tether are ongoing. 48 Currently, the most commonly adopted surgical approach is posterior spinal fusion with or without multiple Ponte osteotomies with derotation techniques to provide correction. Pedicle screw instrumentation is used to sta-bilize the correction, and arthrodesis is augmented with biologics per surgeon preference.…”

Adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity affecting children between the ages of 11 and 18, without an identifiable etiology. The authors here reviewed the available literature to provide spine surgeons with a summary and update on current management options.Smaller thoracic and thoracolumbar curves can be managed conservatively with observation or bracing, but corrective surgery may be indicated for rapidly growing or larger curves. The authors summarize the atypical features to look for in patients who may warrant further investigation with MRI during diagnosis and review the fundamental principles of the surgical management of AIS.Patients with AIS can be managed very well with a combination of conservative and surgical options. Outcomes for these children are excellent with sustained longer-term results.

“…[5] and Samdani et al [6] reported growth-modulating convex vertebral body stapling and/or convex vertebral body tethering as a nonfusion surgical alternative for idiopathic scoliosis that occurs before the onset of the adolescent growth spurt. The published clinical results of that technique are promising [4][5][6].…”

“…The published clinical results of that technique are promising [4][5][6]. The indications chosen for the use of ApiFix® in managing moderate AIS are almost identical to the indications of vertebral body tethering, although the surgical approach (posterior vs. anterior) and the age of the patients are different [6].…”

The standard surgical management of AIS is spinal fusion. Nonfusion solutions for addressing moderate AIS curves are desirable. ApiFix® is a new posterior dynamic device consisting of an expandable ratcheting rod anchored by two pedicle screws to the concave side of the scoliotic spine. It was designed to address single, moderate Lenke type 1 or 5 curves. Surgery is performed without the addition of spine fusion of the instrumented segments. The surgical procedure is short with negligible blood loss and rapid recovery. Deformity correction is achieved by distraction leading to rod elongation. Curve correction is achieved not only during surgery but also after the surgical procedure by performing scoliosis specific exercises. These exercises activate the ratchet with further rod expansion and curve reduction. The reported cases demonstrate the efficacy of the combined approach of surgery and exercises in controlling moderate AIS. This clinical experience with the ratchet device shows consistent curve improvement and stabilization. It lends support to the concept that surgery with this new posterior dynamic device may be a viable alternative to fusion and or as an internal brace in non-compliant brace users for managing moderate AIS curves.

“…However, they are not intended for EOS patients. Shape memory alloy staples and flexible anterior spinal tethers have been tested clinically with promising results [81,82], but none of the devices for spinal growth modulation have been approved for human use by the FDA and thus are still investigational.…”
