Other Body Joints in Motion

Here are videos of other various joints and the motion captured by Future Digital Motion X-Ray.    

Cervical

There is a retrolisthesis of C3 on C4 and C5 on C6 indicating damage to the anterior longitudinal ligament. There is an anterolisthesis of C4 on C5 (damage to the posterior longitudinal ligament), and increased separation between the spinous process at C4-C5 (damage to the interspinous ligament), " avulsion" fracture originating from the anterior/inferior endplate of C4 floating up and down. There is an anterior wedge deformity of the C5 vertebral body indicating a compression fracture and a compression fracture at the vertebral body of C6.     

Wrist

DMX has made diagnosis of wrist instability easy. In this example you see the proximal row of the carpal bones dislocate during wrist flexion and extension.    

TMJ

Motion in the A-P open and closed mouth projection is demonstrated by a sigmoidial deviation of the jaw and the lateral 20 degree tilt view demonstrates asymmetry of the condyles which indicates an internal derangement of the temporal mandibular joint.

Also noted is an audible popping of the condyle.    

Shoulder

There is humeral head dislocation from the glenoid fossa during shoulder abduction.     

Elbow

There is an avulsion fracture (joint mouse) demonstrated in the elbow joints during flexion and extension. Digital Motion X-Ray allows us to view the elbow joint in 360 degrees of motion with the ability to control the penetrating power to detect avulsion fractures that are commonly missed by traditional diagnostic methods.     

Lumbar

Ligamentous injuries can be demonstrated with DMX in the lumbar spine by viewing abnormal coupled motion and increased disc angulations when laterally bending to the right and left. Fixations can also be identified quickly by viewing loss of motion.        

Dysphasia

A modified barium swallow is being performed on a patient suffering from dysphasia (difficulty in swallowing).Picture in Picture (PIP) technology allows external viewing of patient during study. Verbal communication is recorded between speech pathologist and patient through an external amplified auditory microphone.    

Implants

During flexion and extension the stability and integrity of the implant is evaluated and demonstrates a properly functioning implant.
