Abstract
Objective: Surgical correction of scoliosis in small stature children is challenging due to the profile of the posterior instrumentation traditionally available. Concerns are also raised with the use of 5 mm rods for posterior correction. The Paediatric USS is a small stature System.
We studied the correction achieved and the maintenance of the correction at a minimum 15 months follow up using the Paediatric USS.
Design: 20 patients with a minimum 15 months follow up were included in the study. Measurements were made for the initial correction of the Cobb angle to assess correction. At 15 months follow up the cobb angle was measured to assess maintenance of correction.
Results: The average age of the patients was 12 ½ years. The average weight was 32 kgs. The commonest etiology was paralytic(40%) followed by congenital (30%), idiopathic (25%) and collagen disorder (5%). King type II (45%) and type IV (35%) were the commonest type of curves. Combined anterior release and posterior stabilization and fusion was the commonest procedure performed. The average pre op Cobb angle was 77.7°, which corrected to 37.6° i.e. 49%. There was no significant loss of correction at 15 months follow-up.
Conclusions: Thus the Paediatric USS allows adequate correction of the curve and does maintain the correction achieved at a minimum 15 months follow up
