Whip-lash' injuries is caused due to
1. A fall from a height.
2. Acute hyperextension of the spine.
3. A blow on top to head.
4. Acute hyper flexion of the spine
Ans 2
(Ref Maheshwari page 147, CSDT 11th ed 1206)- This injury occurs due to rear end automobile collision.The body of victim is accelerated by the impact force but the head is left behind.Sudden hyperextension followed by sudden hyperflexion occurs. It is mentioned that in mild forms only subtle hyperextension injuries zare found in X Ray.So hyperextension being the primary injury is most important answer.
Other questions about Whiplash-
Characteristic feature is that Plain X ray may be normal. Radiological features suggestive of this unstable injury are
1) Widening of anterior disc space
2) Injury to facets joints, pedicle or lamina
3) Avulsion fractures of anterior vertebral body
4) Retropharyngeal swelling / Fracture of posterior facet.Reversal of cervical lordosis suggests damage to posterior facets and manifests as S Shaped (swan neck deformity)Kyphosis seen most often at C4-C5, C5-C6 levels.
