If your baby was born with radial dysplasia (radial club hand), we know that you and your family are concerned. So, please know that at Children’s Hospital Boston, we will approach your child’s treatment and care with sensitivity and support—for your child and your whole family.
A diagnosis of radial dysplasia refers to a condition in which the radius bone of the forearm is underdeveloped or absent, resulting in a characteristic appearance of a hand and wrist that is angled toward the thumb-side of the forearm.
- Radial dysplasia is a congenital (present at birth) condition in which the radius (the inner bone that connects the elbow to the forearm) did not form correctly in the womb. The radius may be malformed or missing.
In radial dysplasia:
- The affected arm is shorter, with curving of the forearm and stiffness of the elbow and fingers.
- thumb is either very small or missing.
- The occurrence of radial dysplasia is usually sporadic (meaning that it occurs by chance, for no apparent reason), but it may be associated with any of several other defects or syndromes.
- The condition occurs in between one in 55,000 and one in 100,000 babies.
- More than half of babies with radial dysplasia have the deformity in both limbs.
- There are four types of radial dysplasia, corresponding to increasing degrees of severity and complexity. (See Tests for a classification of these types.)
- Treatment usually begins in infancy with splinting, stretching and physical therapy.
- Many affected children, except those with very mild cases may benefit from one or more surgeries, usually starting in the first year of life—but early splinting and stretching can help increase the effectiveness of later treatments.
- Radial dysplasia can occur by itself (in isolation), or can be associated with genetic syndromes.
- Radial dysplasia can recur following surgery in infancy, requiring additional surgery(ies).
