How rare is radial dysplasia?
How rare is radial dysplasia?
Radial dysplasia can occur in any newborn infant. There is no pattern of inheritance. This condition is rare and occurs in approximately 1 in 30,000 to 1 in 100,000 newborns. Boys are affected slightly more often than girls.
What causes club hands in babies?
Babies born with club hand are partially or completely missing one of the two long bones that make up the forearm—the radius or the ulna. As a result, the forearm may be shorter than normal. The hand turns inward, causing limited range of motion at the wrist.
Can radial dysplasia be corrected?
Type 1 Radial Dysplasia This type of radial dysplasia is treated by lengthening the radius through an osteotomy (bone cut) in the distal (lower wrist end) part of the radius. This strategy grows the radius to support the wrist bones (carpus) and correct the relationship between the radius and ulna.
What does it mean to have radial club hand?
It is sometimes called radial club hand, radial dysplasia, or radius deficiency. There are two bones in your baby’s forearm: the ulna, on the outer side of the arm, and the radius, on the inner side. Radial longitudinal deficiency occurs when the radius does not form properly. This causes the wrist to bend toward the thumb side of the forearm.
Where can I get help for radial club deficiency?
The Orthopedic Center’s Hand and Orthopedic Upper Extremity Program and our the Department of Plastic and Oral Surgery’s Hand and Reconstructive Microsurgery Program have treated thousands of babies and children with radial longitudinal deficiency and other hand problems.
Can a baby be born with radial club hand?
The condition affects both arms in about half of children born with radial club hand. It occurs very early in pregnancy between day 28 and 52. In very rare circumstances, exposure to some substances during pregnancy, for instance, thalidomide, can cause problems with the radial bones.
What is the Heikel classification of club hand?
Type 4: Complete absence of the radius with severe radial deviation of the hand and wrist. The Heikel classification is similar to the Bayne and Klug classification system; the differences are not clinically significant.
