Objective:To study on the therapeutic mechanism of an innovated instrumentation-Plate-Rod System for Scoliosis(PRSS) and its effectiveness for the surgical management of idiopathic scoliosis in growing children..Method:To avoid the necessity of repeat operative instrumentation lengthening,a new device PRSS was developed in our department.From October 1998,a total of 200 children with scoliosis were operated on with PRSS.Among them,66 eases who have been followed-up for more than 2 years were evaluated prospectively.The mean age at the time of surgery wasl2.2 years (ranged from 3 to 15 years).Biomechanical test and type X collagen which reflect Chondrogenesis,subchondral bone formation and cartilage degeneration was studied in PRSS-instrumented animal spine model to express the therapeutic biomechanism.
