What position is recommended during lumbar traction when the goal is to open up the intervertebral foramen, separate the facet joints, or elongate the muscles?

• A. Supine with pillow under the knee or small bench under the lower leg
• B. Prone with bolster under the abdomen
• C. Side-lying with knees flexed
• D. Seated with legs extended

Answer: (A)

The main idea is that lumbar traction works best when the spine is placed in a position that increases space where nerves exit the canal. Flexing the lumbar region helps open the intervertebral foramina, and it also allows the facet joints to separate slightly as the vertebrae glide apart. In this setup, keeping the patient supine with a pillow under the knees or a small bench under the lower legs places the lumbar spine into mild flexion, which promotes that foraminal widening and facet separation. It also gently lengthens the posterior spinal muscles, reducing passive tension and making it easier to apply the traction force effectively.

Placing the patient prone with a bolster under the abdomen would bias toward lumbar extension, which tends to reduce foraminal height and compress posterior structures, not what you want when aiming to open those spaces. Seated with legs extended keeps the spine more upright and extended, also not ideal for achieving the foraminal and facet separation goal. Side-lying can influence nearby segments but doesn’t reliably produce the targeted lumbar flexion needed here.
