What Is Focal Kyphosis?

Kyphosis describes a spinal curve. A focal kyphosis is produced by a wedged vertebra. Everyone has a kyphotic curve in their mid-back region which curves outward, but some kyphosis is too extreme.

  1. Location

    • Focal kyphosis usually occurs at the "junction between the thoracic and lumbar regions" of a person's spine, according to the Scoliosis Research Society (SRS). Focal kyphosis is a form of achondroplasia, a bone growth disorder that leads to dwarfism.

    Occurrence

    • Focal kyphosis does not resolve itself as much as generalized kyphosis does. Focal kyphosis also progresses much faster, while generalized kyphosis occurs more frequently. Generalized kyphosis occurs over multiple vertebrae, while focal kyphosis only involves a single vertebra.

    Signs

    • Doctors should look for progressive thoracolumbar kyphosis, or the gradual disruption of the vertebral epiphyseal ring, after a child is 2-years-old for signs of a potential focal kyphosis condition. The SRS recommends that the spine be surgically stabilized if the problem grows past 40 degrees.
