Causes. Today, the term flat back syndrome has been broadened to include any patient with a decrease in lumbar lordosis causing symptoms. As such, flat back syndrome can occur as a result of any condition that shortens the front portion of the spine, causing the patient to lean forward. Flat back syndrome may develop as the result of the following causes: Degenerative Disc Disease, Lumbar Post Laminectomy Syndrome, Compression Fractures, Ankylosing Spondylitis. Degenerative Disc Disease: For some patients, progressive degeneration of the intervertebral discs or the shock absorbers of the spine may lead to a loss of height in the front part of the spine. As discs degenerate the spine begins to lean forward and lumbar lordosis decreases.
