Hip dysplasia in a child

Illustration copyright 2000 by Nucleus Communications, Inc. All rights reserved. http://www.nucleusinc.com

Developmental dysplasia of the hip (DDH) is a childhood condition caused by abnormal development of one or both hip joints. In DDH, the top of the thighbone (femur) does not fit securely into the hip socket (acetabulum), allowing the thighbone to either partially or completely slip out of the socket (dislocate).
