What effect does an increased lumbosacral angle have on lumbar lordosis?

• A. Decreased lumbar lordosis
• B. Increased lumbar lordosis
• C. No effect on lumbar lordosis
• D. Variable effect depending on individual factors

Answer: (B)

An increased lumbosacral angle leads to an increased lumbar lordosis due to the biomechanics and alignment of the spine. When the lumbosacral angle, which is formed between the horizontal plane and the top of the sacrum, becomes larger, this often corresponds with a forward tilting of the pelvis. As the pelvis tilts forward, the lumbar spine compensates by increasing the curvature in the lordotic region to maintain balance and proper load distribution during movement. From a functional perspective, this increased lordosis helps to maintain the center of mass over the base of support, which is essential for effective movement and stability in the human body. Enhanced lumbar lordosis can also support internal organ positioning and the proper alignment of vertebrae, as it aligns the spine in a way that minimizes excessive strain on the intervertebral discs and surrounding musculature. In summary, a larger lumbosacral angle facilitates increased lumbar lordosis, reflecting the interconnected nature of spinal alignment and pelvic positioning, ultimately highlighting the body’s adaptive mechanisms for maintaining posture and function.
