Which muscle tightness is described as attaching from hip to spine and limiting hip mobility?

• A. Piriformis
• B. Glute Med
• C. Rectus Femoris
• D. Tensor Fasciae Latae

Answer: (A)

Piriformis is described here because it runs from the sacrum, which is part of the spine, to the greater trochanter of the femur. That path gives it a direct “hip-to-spine” attachment. When it tightens, it acts like a strap crossing the back of the hip joint, restricting hip mobility—especially external rotation and extension—and can even irritate the nearby sciatic nerve. The other muscles don’t originate from the spine: gluteus medius comes from the ilium to the greater trochanter, rectus femoris starts at the AIIS and crosses the knee to insert on the patella, and tensor fasciae latae runs from the iliac crest to the IT band. So the description best fits the piriformis.
