For a posterior lateral disc herniation on the left, how should you position the patient for intervention?

For a posterior lateral disc herniation on the left, the ideal patient position for intervention is right side lying with a pillow under the trunk while flexing the hips and knees. This positioning takes advantage of the effect of gravity and body mechanics to help alleviate pressure from the affected area.

When the patient is positioned on their right side, it can help to shift the lumbar spine slightly away from the herniated disc, reducing the pressure on the neural structures affected by the left-sided disc herniation. The pillow under the trunk provides additional support, promoting a more comfortable and stable position that can aid relaxation of the paravertebral muscles and the reduction of pain. Flexing the hips and knees modifies the lumbar curve, further relieving tension in the lower back and decreasing discomfort.

This specific positioning contrasts with the other options, as they either do not appropriately address the mechanical effects on the spine relative to the herniation or do not provide the necessary support to optimize comfort and reduce symptoms associated with the condition.
