Abstract

The lumbar vertebral column is a complex structure formed by the fusion of intervertebral joints. It protects the spinal cord

by wrapping around it, carries most of the body’s weight and creates a flexible structure for the body. As individuals with

congenital deformities of the lumbar vertebral column age, they develop some changes in the anatomy of the spine and

with some consequences. In this case, a 35-year-old male patient had a deteriorated posture together with back pain since

childhood. He had walking difficulty and numbness in two legs during walking for the last three years. He fell due to a sudden

brake while he was travelling afoot by bus in 2015. He was admitted to the emergency service with loss of strength in

two legs. Lumbar CT and MRI showed a severe narrowing of the spinal canal due to lumbar kyphoscoliosis. The patient had

neurological deficits after hyperflexion trauma. The patient underwent emergency decompressive surgery due to marked

paraparesis and narrow spinal canal. At the end of the first post-operative month, his clinical complaints were almost completely

resolved, and his biomechanical balance did not show radiological deterioration. While the anatomical change that

occurred during the natural course of congenital kyphoscoliosis increased the stability of the lumbar spine, it severely narrowed

the spinal canal and affected the spinal nerves and thereby caused severe neurological deficits.
