Cleidocranial Dysplasia—An Enigma Among Anomalies

Cleidocranial dysplasia, a rare congenital disorder characterized by dysplasia, and even more rarely, by aplasia of the clavicles, largely goes unrecognized because patients with the condition seldom display functional limitation, pain, or other symptoms. The purposes of this article include describing aspects of cleidocranial dysplasia pertinent to physical therapists and reviewing the few orthopaedic case studies in the literature. The author's goal is to encourage clinicians to screen patients for absence of the clavicles, and to carry out a well-needed study concerning modified arthrokinetics and arthrokinematics associated with cleidocranial dysplasia.J Orthop Sports Phys Ther 1988;10(5):184-188.
