Comparative Study
Surgical management of cervical soft disc herniation. A comparison between the anterior and posterior approach.
Anterior cervical fusion was initially described in the 1950s for cervical spondylotic radiculopathy. The indications for this procedure in the management of soft disc herniation have not been clearly defined. In addition, controversy exists as to whether a cervical soft herniation should be managed by an anterior approach or a posterior cervical laminotomy-foraminotomy. ⋯ There were 27 men and 17 women. The age range was 21 to 52 years (mean, 41 years). The follow-up was 1.6 to 8.2 years (mean, 4.2 years).(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
Evaluation of current extrication orthoses in immobilization of the unstable cervical spine.
An experiment was designed to evaluate the comparative stabilizing efficacy of several widely used semi-rigid orthoses applied to unstable fresh cadaver cervical spines subject to load. Cadaver specimens were surgically destabilized at the C4-5 segment. ⋯ They all provide translational stability while allowing angular changes to occur with application of the flexion force. The Philadelphia Collar Halo System is statistically superior to all three of the aforementioned collars in prevention of both translation and sagittal rotation (P less than 0.05).
