Results of Magnetically Controlled Growing Rods for Early Onset Scoliosis / 대한정형외과학회잡지

ABSTRACT

PURPOSE: To evaluate the first results of surgical treatment using newly developed magnetically controlled growing rods (MCGR) for early onset scoliosis (EOS). MATERIALS AND METHODS: From January 2013 to January 2017, 5 patients, who underwent surgical treatment with MCGR for EOS and were followed for more than one year, were analyzed retrospectively. The demographic and radiology data, including age at surgery, diagnosis, number of lengthening, Cobb angle, T1–S1 length, T1–T12 length, and complications, were analyzed. RESULTS: The mean age of the patients was 6.0±2.7 years old. The subjects were 3 males and 2 females 2 with neuromuscular scoliosis, 1 with syndromic scoliosis, 1 with idiopathic scoliosis, and 1 with congenital scoliosis. The mean number of lengthening was 9.8±2.9 times and the follow-up was 21.6±5.7 months. The Cobb angle improved from 82.0°±28.5° to 48.3°±28.8° at the last follow-up. The T1–S1 length increased from 283.1±72.7 mm to 342.6±86.3 mm at the last follow-up. The T1–T12 length increased from 163.1±50.5 mm to 202.3±65.5 mm at the last follow-up. One screw loosening complication was encountered and there were no neurological complications. CONCLUSION: The treatment using MCGR for EOS is effective and useful.
