76-year-old walks tall after spinal surgery corrects severe hunchback

A 76-year-old man in Taiwan, identified as Mr. Zeng, regained his dignity after undergoing a minimally invasive spinal surgery to correct severe kyphosis. His condition had worsened over time, forcing him to walk with his head perpetually bowed. Initially resigned to living with his hunched posture, persistent neck pain prompted him to seek medical attention. Doctors diagnosed him with degenerative disc disease in his lumbar spine, which had caused a significant imbalance in his spinal and pelvic mechanics. To maintain an upright stance, his body had developed compensatory mechanisms, leading to muscle fatigue and an increased risk of falls due to a forward-shifted center of gravity. The medical team at Yuanrong Hospital opted for a minimally invasive oblique lateral interbody fusion (OLIF) procedure. This technique involved inserting a large interbody fusion device from the side, acting like a 'jack' to restore the collapsed disc height and lumbar lordosis. The approach avoided damaging major back muscles and nerve bundles, significantly reducing the risk of muscle damage and postoperative numbness, which is crucial for elderly patients. Following the surgery, Mr. Zeng can now walk with his head held high and chest out, a stark contrast to his previous posture.

The patient's pain stemmed from a mechanical imbalance between the spine and pelvis. As the intervertebral discs degenerate, the normal forward curvature of the lumbar spine gradually disappears. To maintain standing, the body activates compensatory mechanisms.
