Treatment algorithm
Please note that formulations/routes and doses may differ between drug names and brands, drug formularies, or locations. Treatment recommendations are specific to patient groups: see disclaimer
screening scoliometer measurement <5° or coronal Cobb angle measurement of ≤10°
regular exercise
The patient should be advised to maintain a regular fitness routine, specifically toward developing improved core strength and conditioning.
observational monitoring
Treatment recommended for ALL patients in selected patient group
If the patient or family identify worsening postural asymmetry or the patient develops symptoms to suggest the presence of another underlying cause for the spinal deformity, observational monitoring with follow-up standing PA and lateral scoliosis x-rays should be undertaken at 4- to 12-month intervals (depending on the estimated rate of growth and remaining growth potential at the time of evaluation).
standing coronal Cobb angle measurement of 11° to 20°

bracing
Many brace options are available, and the specific type of orthotic used varies from surgeon to surgeon and country to country. Braces commonly used in the US are the Boston and Rosenberger braces and the Charleston bending brace.
Several brace-wearing schedules exist, ranging from 23 hours per day to nighttime-only bracing. The International Scientific Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) consensus supports the use of an 18-hour-per-day bracing schedule.[31]Negrini S, Donzelli S, Aulisa AG, et al. 2016 SOSORT guidelines: orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth. Scoliosis Spinal Disord. 2018;13:3. https://www.doi.org/10.1186/s13013-017-0145-8 http://www.ncbi.nlm.nih.gov/pubmed/29435499?tool=bestpractice.com Other organizations have also attempted to develop “Consensus of Care” statements and guidelines in an effort to standardize scoliosis brace treatment protocols.[31]Negrini S, Donzelli S, Aulisa AG, et al. 2016 SOSORT guidelines: orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth. Scoliosis Spinal Disord. 2018;13:3. https://www.doi.org/10.1186/s13013-017-0145-8 http://www.ncbi.nlm.nih.gov/pubmed/29435499?tool=bestpractice.com [57]Kotwicki T, Durmala J, Czaprowski D, et al.

The goal of brace treatment is to prevent curve progression until skeletal maturity, at which time the risk of further curve progression significantly reduces.
Data from the BrAIST (Bracing in Adolescent Idiopathic Scoliosis Trial) trial have shown a significantly lower risk of curve progression in patients with AIS who wore a brace compared with those who did not.[45]Weinstein SL, Dolan LA, Wright JG, et al. Effects of bracing in adolescents with idiopathic scoliosis. N Engl J Med. 2013 Oct 17;369(16):1512-21.

One Cochrane review concluded that all of the included studies consistently showed that bracing in AIS prevented curve progression, including 7 separate studies that included a total of 662 participants.[59]Negrini S, Minozzi S, Bettany-Saltikov J, et al. Braces for idiopathic scoliosis in adolescents. Cochrane Database Syst Rev. 2015 Jun 18;(6):CD006850.

standing coronal Cobb angle measurement of >45°
surgical spinal arthrodesis
Spinal arthrodesis with instrumentation aims to achieve maximal deformity correction, improve appearance with trunk balancing, stop continued curve progression, and reduce short- and long-term complications related to the spinal deformity.[60]Dickson JH, Mirkovic S, Noble PC, et al. Results of operative treatment of idiopathic scoliosis in adults. J Bone Joint Surg Am. 1995 Apr;77(4):513-23. http://www.ncbi.nlm.nih.gov/pubmed/7713967?tool=bestpractice.com
The choice of surgical approach and instrumentation technique is dictated by the characteristics of the deformity (e.g., location of the curve apex), degree of spinal flexibility, and surgeon preference.[60]Dickson JH, Mirkovic S, Noble PC, et al. Results of operative treatment of idiopathic scoliosis in adults. J Bone Joint Surg Am. 1995 Apr;77(4):513-23.

Most deformities are treated with a posterior approach, although some surgeons use an anterior approach with the belief that the deformity can be corrected with a lower number of fused levels.[65]Muschik MT, Kimmich H, Demmel T.

However, this approach has a higher incidence of implant failure and pseudarthrosis, and has been associated with a risk of pulmonary complications secondary to the need for "single lung" anesthesia during the procedure.[74]Betz RR, Harms J, Clements DH 3rd, et al.
