High-signal-intensity edema and susceptibility artifact from hemorrhage within the spinal cord may accompany these findings. Although adhesions are necessary to repair and mend torn soft tissues, if excessive adhesions are allowed to form, the tissue will lose its mobility, resulting in decreased ranges of motion. A basic understanding of the complex anatomy of the finger and of common tendon and ligament .

This ligament connects the proximal phalanx to the middle phalanx on the palm side of the joint. The terms whiplash and acceleration injury to the neck describe an injury mechanism without specifying a pathology.
