The early results of treatment of idiopathic scoliosis with the Kyushu University Underarm Brace (K. U. U. B.) were studied in 70 patients, whose ages ranged from 2 to 19 years (average, 13.5 years) at the beginning of treatment.
These 70 patients had 102 separate curves, and followed for six months or more after the beginning of brace treatment (average, 16.8 months; range, 6 to 45 months). The mean initial curvature was 26.9 degrees.
The average percent correction at follow-up was 38.7% in 44 thoracic curves with the apex below T7. The mean T1-tilt in degrees was 0.06° before treatment and —0.99° in brace at follow-up.
The K. U. U. B. was effective for thoracic curves that apices located below T7 without out of balance.
