Subtransverse process wiring - A new technique of segmental spinal fixation of the thoracic spine or in the treatment of adolescent idiopathic scoliosis

Study Design. Segmental fixation is the preferred technique for the surgica l treatment of adolescent idiopathic scoliosis. Sublaminar wiring is a wide ly used, strong type of segmental fixation. The most common drawback of the sublaminar wiring is the risk of neurologic injury. The authors have appli ed subtransverse wiring for 3 years, and the technique seems promising. Objectives. To show that subtransverse wiring is a technique strong enough to correct scoliosis curves and does not carry neurologic injury risks. Summary of Background Data. Sublaminar wiring is a commonly used fixation m ethod for posterior fusion in the treatment of scoliosis. Because of its as sociated risk of neurologic injury, it is mostly recommended for long neuro muscular curves. Methods. The authors used the subtransverse wiring technique in 12 cases of adolescent idiopathic scoliosis and followed them for an average of 22 mon ths. Results. The average correction rate was 65%, and correction loss at the en d of the follow-up period was 5 degrees. No neurologic complications were e ncountered. Conclusions. Subtransverse wiring is strong enough to correct scoliotic cur ves. It requires less operative time and skill and is neurologically safe.
