Which of the following are common alignment anomalies of the hips and legs?

• A. Anterior Pelvic Tilt
• B. Posterior Pelvic Tilt
• C. Pelvic Up Slip
• D. All of the above

Answer: (D)

The hips and legs often show several common alignment patterns, reflecting how imbalances in the pelvis influence the lower body. Anterior pelvic tilt means the front of the pelvis drops and the back rises, typically from tight hip flexors and lower back muscles with weaker abdominals and hamstrings, which can increase the curve in the lower spine and alter leg alignment. Posterior pelvic tilt is the opposite: the front of the pelvis tilts up, flattening the lumbar spine, usually due to tight hamstrings, glutes, or abdominal muscles and relatively weaker hip flexors. Pelvic up-slip refers to one side of the pelvis sitting higher than the other, creating asymmetry that can affect hip, knee, and ankle alignment as the body compensates. Because these patterns are all commonly seen in people and can occur together or separately, recognizing them all reflects the typical range of hip–leg alignment anomalies.
