A CASE OF SCOLIOSIS SECONDARY TO HIGH GRADE DYSPLASTIC SPONDYLOLISTHESIS AND ITS MANAGEMENT

Scoliosis is dened as a structural deformity of the spine in all three dimensions and diagnosed if the Cobb angle is ≥10 degrees. Scoliosis may be associated in upto 48% cases of spondylolisthesis, being more commonly encountered in high grade listhesis (>50% slip) and is often seen in dysplastic types. We are reporting a case of a 12 year old premenarchal female with progressive deformity of back and chest for 10 months associated with back and leg pain. Radiographs revealed grade 4 dysplastic spondylolysthesis with a long C shaped curve (King type 4) with left convexity. Reduction of lysthesis and instrumented fusion from L4 to S1 was performed. Post operatively there was immediate correction of scoliosis with resolution of clinical symptoms. Knowledge about olisthetic scoliosis helps in early identication of patients with scoliosis caused by spondylolisthesis, who require surgery only for the latter condition, avoiding unnecessary surgery for scoliosis.
