Urgent closed reduction of the dislocated cervical spine in New Zealand

Emergent decompression, either by closed reduction or surgical decompression, of the acutely compressed cervical spinal cord is recognized as important in minimizing the neurological outcomes of these injuries. The aim of this study is to optimize New Zealand's capability to perform closed reductions.

Regional hospitals throughout New Zealand were surveyed on their capability to reduce acute cervical spine dislocations using traction. A systematic literature review was performed to investigate aspects of patient selection, reduction technique and the outcomes achieved with closed reduction of such injuries. This information was combined with our local experience to develop an evidence-based guideline.

Most (12/14) of the regional centres throughout New Zealand have recent experience, remain willing and have the resources necessary to reduce appropriate cervical spine injuries using traction. Fourteen published studies from nine countries detail a 75% success rate from 363 cases of attempted closed reduction, with the greatest neurological recovery noted in patients with shorter time period from injury to reduction. One patient suffered neurological worsening. The published protocols were compared and coupled with our local practice to create an online, step-by-step, evidence-based reference to help clinicians in regional hospitals perform a safe and successful closed reduction.

To optimize the capability of inexperienced personnel to perform closed reductions in a safe and timely manner, we have developed an online, step-by-step, evidence-based reference (www.closedreduction.co.nz). This forms part of New Zealand's strategy to achieve urgent cord decompression for appropriate cervical spinal cord injuries.
