The effect of Cobb angle correction on spinal length gain in patients with adolescent idiopathic scoliosis

The relationship between curve correction and spinal length gain in adolescent idiopathic scoliosis was examined. A total of 102 patients who underwent posterior spinal correction and fusion alone or in combination with anterior spinal correction and fusion (ASF) were studied. The Cobb angle correction, increase in the main thoracic length, T1–L5 spinal length gain, and T1–L5 spinal length gain/Cobb angle correction were reported. The length gain/Cobb angle correction value was not significantly associated with sex, fusion approach, and the number of fused levels. Surgical T1–L5 spinal length gain (mm) equaled (70.20)−(3.51)×(degrees of Cobb angle correction)+(0.08)×(degrees of Cobb angle correction)2.
