Description

<p>  Background and Objecttive : Sciatic scoliosis caused by lumbar disc herniation is also known as functional scoliosis, which can be treated with discectomy ; However, there have been few reports on the appropriate surgical management of severe sciatic scoliosis and the post operative changes.</p><p>  The authors report experiences of 2 patients who had a Cobb angle greater than 20° and showed reduction in scoliosis after discectomy.</p><p>  Clinical presentation : Case 1. A 23-year-old woman who had pain in her right leg and numbness caused by L4/5 disc herniation for 4 years presented with severe scoliosis and an L2-5 Cobb angle of 31.3° before surgery. After discectomy, her scoliosis improved to 10.1° in 1 month and 7.9° in 4 months. Case 2. A 30-year-old man who had pain in his left leg and numbness and low back pain caused by L4/5 disc herniation for 3 months presented with scoliosis and an L1-5 Cobb angle of 24.7° before surgery. After discectomy, his scoliosis improved to 5.4° in 1 month and disappeared in 3 months.</p><p>  Conclusions : Two patients with severe sciatic scoliosis due to lumbar disc herniation before surgery showed improvement in scoliosis from the early period after discectomy without spinal fixation. The authors suggest that discectomy without spinal fixation is an adequate surgical approach for sciatic scoliosis, even if the scoliosis is severe.</p>
