Cervical Hyperextension Research Articles

Fetal cervical hyperextension in breech presentation

I read with considerable interest the article by Dr. J. G. B. Russell and Dr. Margaret R. C. Aird in the British Journal of Radiology of July 1976 on the above subject. It has been my experience over several years that hyperextension of the cervical spine of the fetus in the antenatal radiograph is sometimes associated with the presence of the umbilical cord being wound round the fetal neck and it may well be a cause of fetal distress during labour.

Reduction of tension at the anastomosis following tracheal resection in puppies

Inlying tracheal "stay sutures" and submandibular sutures to prevent cervical hyperextension were used separately and in concert to limit anastomotic tension following tracheal resection in puppies. Study of the degrees of stenosis in the mature dogs indicates the effectiveness of the principle.

Clinical Studies on Central Spinal Cord Injury (involved only in the upper limbs)

We experienced 8 patients with central spinal cord injury who displayed motor and sensory impairment involved only in the upper limbs. Roentgenograms of these patients showed narrowness of the antero-posterior diameter of the spinal canal measured at the level of 5th cervical spine. We think that the mechanism of the injury is due to cervical hyperextension. These symptoms (motor and sensory impairment) were ascribed to injury of anterior horn cells and poeterior horn cells. Motor and sensory impairment of our cases was transient, and it disappeared by 7 weeks (average) after injury. These patients were treated with conservative method. These cases were compared with type I (our classification) of myelopathy in cervical osteochondrosis.

LATERAL-FLEXION NECK INJURIES IN ATHLETIC COMPETITION.

Neck injuries are infrequent in college athletes compared to extremity injuries but are especially important because of their serious potential. Schneider 1 has discussed the possibility of fatal outcome from cervical hyperextension in football, when the face bar of the helmet is used as a lever to force the head backward. In our experience, a more common injury is a lateral neck sprain, the so-called nerve pinch in trainers' terminology. The typical injury is a blow on the side of the head, with immediate pain from the base of the neck to the hand, prickly paresthesia of the whole arm, and inability to move the extremity. Within a few minutes, this set of sensations disappears, leaving a dull ache in the neck and shoulder of the affected side. Within a few more minutes, the injured player is seeking and often obtains permission to return to the game. Only later does
