Intraoperative reduction of locked facets in the cervical spine by use of a modified interlaminar spreader: Technical note

OBJECTIVE: Facet dislocations commonly require intraoperative reduction aft er closed reduction with traction has failed. Reduction should be performed in a gradual, controlled fashion to prevent additional inadvertent spinal cord compromise. METHODS: We describe a new technique for safe and simple dorsal reduction o f facet dislocations by use of a modified interlaminar spreader. This techn ique requires only minimal controlled manipulation of the spine. RESULTS: We have used this technique in 52 consecutive patients with no com plications or failures related to its use in open reduction. This technique increases the stability of the cervical spine after reduction because it l imits bone removal from the facet joints. CONCLUSION: This technique provides a feasible and reliable approach to ope n reduction of cervical facet dislocations via the posterior approach.
