Magnetically controlled growing rod in 13 patients with early-onset scoliosis and spinal improvement.

Abstract

The aim of this study was to examine the use of magnetically controlled growing rods as a method of providing spinal improvement while preventing thoracic insufficiency in patients with early-onset scoliosis (EOS). Of a total of 13 patients, 4 patients underwent a dual magnetic rod implantation, while 9 patients had a single magnetic rod procedure. The study group comprised 12 (93%) female and 1 (7%) male patients. Six patients (46%) had an idiopathic form of scoliosis, in 4 (30%) it was congenital, and in 3 (23%) it was neuromuscular scoliosis. The patients' Cobb angles, thoracic kyphosis, T1-T12 and T1-S1 distance prior to and following the treatment were compared. The mean Cobb angle before surgery was 53.78⁰, whereas it decreased to 39.29⁰ postoperatively (p < 0.001). The mean thoracic kyphosis angle was 40⁰ before and 29.79⁰ after surgery (p < 0.001). The mean T1-S1 distance was 32.14 cm before and 36.36 cm after surgery (p < 0.001). The mean T1-T12 distance was 18.69 cm before and 20.64 cm after surgery (p < 0.001). The use of magnetic rods is an effective method of EOS treatment. It allows for spinal growth while managing the progression of the scoliosis. Level IV, therapeutic study.
