Posterior ISOLA segmental spinal system in the treatment of scoliosis.

The aim of the current study was to evaluate the effectiveness and safety profile of the posterior ISOLA Segmental Spinal System in the treatment of scoliosis. Forty-one patients (31 girls, 10 boys) were reviewed retrospectively. The average age was 14.2 years and the mean follow-up was 24 months. There were 32 cases of idiopathic scoliosis, 5 cases of neuromuscular scoliosis, and 4 miscellaneous types. An average of 12.3 levels were fused posteriorly. The average preoperative Cobb's angle, apical vertebral rotation, apical vertebral translation, lumbar lordosis, and thoracic kyphosis were 65.9 degrees, 2.2, 47.8 mm, 40 degrees, and 28 degrees, respectively. The corresponding postoperative data were 34.4 degrees (47.8% correction), 1.8, 23.1 mm, 40.2 degrees, and 26.7 degrees. There were five minor complications and one deep wound infection. The ISOLA Segmental Spinal System was an effective and safe posterior system that could be used in different types and patterns of scoliosis with low complication rates.
