Seven female and three male patients with idiopathic scoliosis were treated surgically with the Isola Splnal Instrumentation at the 3rd Department of Orthopaedic Surgery and Traumatology of Ankara Numune Hospital, between the dates July 1993 and November 1995. The age at operation ranged from 9 to 24 years with an average of 13.6 years. The type of the curve according to King's classification was type II in 1 curve, type III in 7 curves and type IV in 2 curves.

Preoperative and postoperative horizontal plane analyses of totally 11 curves were made by using the Perdriolle torsio meter. The average measurement values were 25.00° ± 7.75° (15° - 40°) preoperatively and 19.55° ± 8.50° (10° - 35°) postoperatively. The amount of average correction was 20%. Statistical analysls of the data was made by using student t-test, and it was seen that there was no statistically significant difference (p = 0.066) between the preoperative and postoperative measurement values of the curves in the horizontal plane.

İt was concluded that, although the frontal plane correction, obtained with the Isola Spinal Instrumentation was very significant (p<0.001), the amount of horizontal plane correction of an idiopathic scoliotic curve, treated with this system was not as notable as the frontal one.
