hip AFTER INJURY
2. Congenital hip
dislocation (CHD), also called developmental dysplasia of the hip,
occurs when a child is born with an unstable hip due to abnormal
formation of the hip joint during early stages of fetal development.
This instability worsens as the child grows. In some cases, the
ball-and-socket hip joint may dislocate periodically, with the ball
slipping out of the socket with movement. Sometimes, the joint may
be completely dislocated. According to a 2006 article published
in American Family Physician, one out of every 1,000 infants is born
with a dislocated hip.
