Differentiated approach to Chêneau brace choice for the scoliosis treatment

Background and purpose

To validate choice of the Cheneau brace according to scoliotic deformity type.

Materials and methods

Study group included 1700 patients with AIS treated by Cheneau brace [1]. Major deformity Cobb angle ranged 20°-40°, spinal rotation ranged 15°-35°. Age of the patients was ranged 11-15 years old. Radilogic mesurements and clinical presentation of the spinal deformity during the investigation were assesed [2]. Mean follow-up was 5 years. In this study Rigo's clinical and radiological criteria [3] and SRS terminology were used.

Results

According to obtained data four scoliotic deformity patterns were defined: primary thoracic and secondary lumbar/thoracolambar curve (pattern 1); primary thoracolumbar and secondary lumbar curve (pattern 2); primary lumbar curve with/without secondary thoracic curve (pattern 3); triple curve deformity (pattern 4). This classification allowed to deifine following 6 brace types : for 1 pattern - braces of Tl, T2, T3 types. For 2 pattern - brace T3 type; for 3 pattern - braces of L1, L2, Tl and T2 types. For 4 type pattern - brace of CTL type.

Conclusions

Scoliosis deformity classification provides differentiated Cheneua brace selection according to the deformity pattern.
