Hyperkyphosis

From Wikipedia, the free encyclopedia

Hyperkyphosis, colloquially called “dowager’s hump,” refers to excessive kyphotic, or anteriorly concave, curvature of the thoracic region of the spine. A kyphosis angle over 40° - the 95th percentile value for young adults - is currently used to define hyperkyphosis.[1] [2]
