Which outcome increases due to spinopelvic limitations requiring greater hip flexion?

• A. impingement and dislocation
• B. infection
• C. fracture
• D. osteoarthritis

Answer: (A)

When the spine and pelvis can’t rotate freely, the body must rely more on the hip to achieve bending or forward-reaching movements. That means the hip has to flex farther than usual. This extra hip flexion brings the femoral neck into contact with the acetabular rim earlier in the motion, leading to impingement. If the joint is pushed beyond its safe ROM, the head can slip out of the socket, increasing the risk of dislocation, especially with a hip prosthesis. Infections, fractures, and osteoarthritis aren’t direct results of needing more hip flexion due to spinopelvic limitations. So the associated increase is impingement and dislocation.
