Spondyloepiphyseal dysplasia with metatarsal shortening

Spondyloepiphyseal dysplasia (SED) with metatarsal shortening (formerly called Czech dysplasia) is an inherited condition that affects joint function and bone development. People with this condition have joint pain that begins in late childhood or adolescence. The cartilage in their hips, knees, shoulders, and spine usually degenerates over time (osteoarthritis), which may impair their mobility. Due to these severe joint problems, people with SED with metatarsal shortening may require joint replacement in early adulthood.

Description

Spondyloepiphyseal dysplasia (SED) with metatarsal shortening (formerly called Czech dysplasia) is an inherited condition that affects joint function and bone development. People with this condition have joint pain that begins in late childhood or adolescence. The cartilage in their hips, knees, shoulders, and spine usually degenerates over time (osteoarthritis), which may impair their mobility. Due to these severe joint problems, people with SED with metatarsal shortening may require joint replacement in early adulthood.

People with SED with metatarsal shortening often have shortened bones in their third and fourth toes, which make their first two toes appear unusually long. Affected individuals may also have abnormalities in the bones of the spine (vertebrae), including flattened vertebrae (platyspondyly), a reduction in the space between the vertebrae, or an abnormal curvature of the spine. Some people with SED with metatarsal shortening have progressive hearing loss.
