Halifax clamps: efficacy and complications in posterior cervical stabilization.
Trauma, neoplasia, rheumatoid arthritis, Down's syndrome, and inflammatory conditions are well-known causes of spinal instability. The Halifax clamp is a method of posterior cervical stabilization that is attached to the adjoining laminae and tightened until no movement between involved vertebrae is possible. Our experience with cases that have utilized Halifax interlaminar clamps, their results and complications are presented. ⋯ Halifax interlaminar clamps are a safe and effective method for posterior stabilization of various causes of cervical spinal instability.

Percutaneous radiofrequency cordotomy remains a useful modality for managing selected patients with unremitting pain due to malignancy. Although the lateral C1-C2 method is widely used, certain clinical situations may call for a low anterior cervical approach via the disc space. The anterior method can be technically exacting due to the need for precision in the angle of approach at the point of disc space entry. Here we describe how CT-imaging can be used to simplify target localization during percutaneous anterior cervical cordotomy.
