Effects 3 Bone 11

Page history last edited by Emily Ryan 12 years, 11 months ago

 

Van Buchem's syndrome is a skeletal disorder.  Almost all of the effects are bone-structure defects.

The most common symptoms of Van Buchem's syndrome are:

  • Thickening of skull bone

  • Thickening of collar bone

  • Thickening of jaw bone

  • Thickening of rib bones

  • Thickening of main shaft of long bones

  • Facial nerve paralysis (due to nerve entrapment)

  • Inability to sense (feeling) due to nerve entrapment

  • Wide chin

  • Papillary edema  [1]

  • Increased bone strength

  • Increased bone radius

  • Increased bone mineral density[2]

 

This image shows a patient who was diagnosed with Van Buchem's sydrome. A thicker jaw bone and an abnormally wide chin are distinctly noticeable in the photo.

The above image shows a Van Buchem patient's skull on the right in comparison with three unafflicted, normal human skulls. The weight of the skull on the right is almost equal to the weight of four normal skulls [3].

 

To see why the bones become so unusually heavy please see the Bone Growth page.

 

 

Below are X-ray images of normal patients and also X-rays of patients with Van Buchem's Syndrome

That picture of the skulls is almost unbelievable! It's really shocking to actually be able to see the difference between the density of the bones. Try swimming with bones like the ones on the right.
