The bones of the skull and face collectively make up the most complex area of skeletal real estate in the body. Analysis of the fractured face requires a knowledge of not only normal anatomy, but also of common fracture patterns in the face.

Most spinal cord injuries are attributed to trauma. Absence of radiographic findings does not exclude a spinal cord injury. A substantial portion of spinal cord injuries in children (25%...

Hurler disease (gargoylism)

There are 6 ossification centers around the elbow joint. These ossification centers all appear at different ages and they all fuse to the adjacent bones at various ages. It is not clinically important to memorize the specific ages of when these ossification centers appear or fuse. However, it is clinically...

Low back pain attributed to spinal disk degeneration has been routinely diagnosed via diskography. Although its validity has been debated, diskography represents a diagnostic tool to help differentiate pain that is diskogenic in nature from other etiologies of low back pain.[1-5] The procedure carries short-term risks such as bleeding, infection...
