Abstract
Five cases of luxution of lower cervical vertebrae with interlocking of unilateral facet were surgically trated with AO-H plates for stabilization.
In the initial case, recurrence of luxation occured after reduction and immobilization with skull traction for more than one month.
So, all cases were reduced and immobilized with AO-H plate after excision of the intervertebral disc and insertion of anterior bone graft under general anesthesia.
Rigid stability and bone fusion of well aligned cervical vertebrae were gained on all cases after short period; after bed rest for one week and immobilization with neck collar for three weeks on the latter case. It is concluded that AO-H plates are very useful for their rigid stability, small mass and ease for use.
