Anterior and posterior Correction for Severe Paralytic Scoliosis / 대한정형외과학회잡지

ABSTRACT

Since anterior approach to scoliosis was first reported by Dwyer in 1969, many orthopedic surgeons have treated scoliosis of a large variety of causes through a direct approach to the anterolateral portion of its convexity. Four cases of severe and paralytic scoliosis were treated by anterior and posterior approaches of the spine at the Department of Orthopedic Surgery of Seoul National University Hospital from April 1975 to April 1977. Among four cases, one case had bony fusion in the posterior element of the lumbar spine with 126 curvature from T11-to L5, which was corrected by lumber anterior discectomy on the first stage and osteotomy in the posterior element between L2 and L3 following Harrington instrumentation, resulting in 86 curvature. The other three cases were treated by Dwyer instrumentation primarily and then posterior fusion including sacrum with Harrington instrumentation 3 weeks after the first anterior approach, resulting in the average 70.1% correction which is compared with the average correction of 53.8% with Harrington instrumentation in our hospital.
