Segmental Sublaminar lViring Method (SSI), is being used especially in the surgical treatment of idiopathic scoliosis, neuromuscular spinal deformities and vertebral fractures. There are many studies reporting high correc-tion loss and complication rates of this system. İn this study 21 patients whom were treated by Luque-SSI or Hartshill-SSI at the 1st Orthopaedics and Traumatoiogy Clinic of Ankara Social Security Hospital between October 1991 and January 1992 were evaluated. Mean foiiow-up period was 13.2 (6-21 m) months. When ali the patients with idiopathics scoliosis were inciuded mean Cobb angles of the main curves w er e corrected by 45.2 % (28.9 % -73.3 %). İn 30.8 % of the patients in this group normalphysiological kyphosis was restored. 28.2 % (26.3 % - 31 %) and 70 % of corrections were obtained in 3 neuromuscular scoliotic patients with petvic tüt and in 1 neuromuscular scoliotic patient without pelvic tiit whom Galvestone method was used, respecially. During follow-up average-ly 17.3° (3°-45°) of correction loss in idiopathic scoliosis and 21.3° (13°-34°) of correction loss in neuromuscular scoliosis were observed. Complications occured in 57.1 % of the patients. 14.3 % neurologic deficit and 4,8 % post-operative exitus was seen.
Based upon these findings it was thought that besides high correction rates with sublaminar wiring method, this system could be used only in selected cased as it has high neurologic deficit risk and high complication rates.
