title: The natural history of scoliosis: curve progression of untreated curves of different aetiology, with early (mean 2 year) follow up in surgically treated curves.
abstract: We studied the curve progression of untreated curves presenting to the Scoliosis Service of Hospital Kuala Lumpur. One hundred and fifty-two (152) patients were included in this study. The median rate of curve progression of idiopathic scoliosis curves was 7.03 degrees per year, for neuromuscular scoliosis curves was 17.39 degrees per year; and congenital scoliosis curves were 3.67 degrees per year. These rates are similar to the reported rates in the literature. Data for sixty-one (61) surgically treated patients were reviewed to determine the early curve correction of the curves of different aetiology. The mean age of surgery was 14.15 years old, the mean preoperative curve size was 71.61 degrees; and the mean postoperative curve size was 43.78 degrees. The mean duration of follow up after surgery was 2.44 years. The revision and removal of instrumentation rate was 8.3%.
