Lumbosacral scoliotic list by lumbar disc herniation

Area of Science:

• Spine surgery
• Neurosurgery
• Orthopedic surgery

Background:

• The relationship between lumbar disc herniation and scoliotic list is established.
• Limited research exists on the specific correlation between herniation location and scoliotic list direction.

Purpose of the Study:

• To investigate the association between lumbar disc herniation location and sciatic scoliosis direction.
• To elucidate the underlying mechanisms of sciatic scoliosis.

Main Methods:

• Prospective study of 45 patients undergoing open discectomy for lumbar disc herniation.
• Measured scoliotic list direction, Cobb's angle (pre/post-op), and L1 vertebral displacement.
• Documented herniation location, side, and degree during surgery.

Main Results:

• No significant association found between herniation location/degree and scoliosis direction/degree.
• No significant association found between herniation location/degree and L1 vertebral displacement.
• Significant association identified between the side of disc herniation and the direction of sciatic scoliosis.
• Surgical decompression led to resolution of most sciatic scoliotic lists.

Conclusions:

• Sciatic scoliosis direction is linked to the side of disc herniation, not its location.
• The side of herniation is a key factor in predicting the direction of sciatic scoliosis.
