Lordosis, a curvature of the spine, affects the lower lumbar region. This condition is sometimes referred to as “swayback” or “saddleback” because the spine curves inward, much the same as a horse with a broken down back. Physical therapy to strengthen muscles in the lower back and hamstring regions of the legs, along with a brace, are the typical treatment for lordosis. In extreme cases, surgery can be done to fuse the vertebra together. Surgery should be a final option. A 3-D model bent to the same shape as the curvature aids in diagnosing the proper care and pre-planning surgery if necessary. With a 3-D model, the surgeon can better determine which discs need fused together to correct the condition. This saves time in the operating room and leads to a quicker recovery.
