End-growth results of a personalised conservative approach in 1938 high risk adolescents with idiopathic scoliosis: Prospective observational multicentre study

Introduction/Background End of growth RCTs showed the efficacy of bracing and physiotherapic scoliosis specific exercises (PSSE). Current guidelines propose PCA according to the step-by-step theory: invasivity increases with treatment intensity, from observation to PSSE to soft, rigid and very rigid bracing. This requires to set individualised outcomes and propose the less invasive treatment according to the outcome. Material and method Inclusion criteria: AIS, 11–45°, Risser 0–2, age 10–16, first consultation, no previous bracing. End of observation: Risser 3, medical prescription. Groups were defined according to the main end outcome (SRS-SOSORT Consensus): low degree (LD) (  30° at start) remain  Results We excluded 207 (10.7%) drop-outs and 274 (14.1%) still in therapy. Treatment intensity increased with Cobb degrees, as well as rate of improvement (from 13.6% to 56.1% – P P P  50° at the end were 1.6%. Conclusion Defining different outcomes according to PCA allows to perform less aggressive treatments for LD, and concentrating the efforts in HD. Failure rates can be low in both groups. Progression is not the best outcome for all patients and type of treatments.
