A 3D German-designed brace used to treat adolescent idiopathic scoliosis

Introduction Adolescent Idiopathic Scoliosis (AIS) is a condition that affects an otherwise healthy child 10 years of age or older and is the high risk of severe deformity and surgery. Different brace applications include the Milwaukee Brace, Boston Scoliosis Brace, TLSO and others, and the success rates of orthoses vary. With little experience in the use of the Chêneau-type corset, the brace provides an effective means for the active correction of scoliotic spinal deformity.The objective was to demonstrate an outcome with a 3D functional corrective German-designed corset used to treat a patient with AIS in the period from the onset of the curve to the onset of skeletal maturity.Material and methods The medical history of patient S. including anamnestic, clinical and radiological findings recorded 2018 and 2023 when she used a 3D German-designed (3D GD) corset. The corset design was defined as 3CL/B2 according to the Lehnert - Schroth scoliotic classification as modified by Rigo.Results The left-sided thoracolumbar curve of a 9-year-old patient with a Risser sign of 0 and a Cobb angle of 25° at baseline decreased to 12° at the age of 16 years (Risser sign - 5) due to bracing.Discussion The AIS was diagnosed in the patient at the age of 5 years and bracing was initiated at the age of 9. The curve correction using 3D GD brace was based on the principles offered by Chêneau. The patient used the corset for 20 hours per day. The initial brace correction was 90 %. The curve decreased from Cobb angle 25° to 12° over a six-year period of brace treatment with no need for surgery. Three cases with identical outcomes were reported with the use of the Boston and Chêneau braces in AIS.Conclusion The clinical case showed effective use of the 3D GD corset as a new exponent of corsets developed on the principles offered by Chêneau to prevent surgical treatment by the time of skeletal maturity.
