Awake Rapid Heavy-Weight Closed Reduction (ARHWCR) with weights from 18 to 72 kg was used to reduce six unilateral and nine bilateral cervical facet dislocations. Frankel grading ranged from A to E. Reduction was achieved in all 15 patients with no neurological deterioration. Motor ASIA score improved from a prereduction mean of 64 points to 73 after reduction.

Before and after reduction, MRI studies were done on all 15 patients. ARHWCR was done irrespective of the MRI findings. The MRI results were evaluated by five orthopaedic surgeons, five neurosurgeons and five radiologists. The radiologists reported 55% disc herniation in four neurologically-intact patients. On pre-reduction MRI, 34% of anterior longitudinal ligaments and 64% of posterior longitudinal ligaments were reported to be disrupted. They were reported intact on post-reduction MRI.

These findings indicate that MRI studies may be open to misinterpretation. Viewing the prereduction MRI, the orthopaedic and neurosurgeons opted for surgical decompression and reduction in 53% of cases. Looking at the post-reduction MRI, they felt that reduction was adequate in 80.6% of cases, but on personal judgment believed that surgical decompression might be of benefit in the remaining 19.4%.

ARHWCR is an effective, safe and rapid way of relieving cord compression. Prereduction MRI, irrespective of the patient’s neurological status, is not indicated in acute cervical facet dislocations and can lead to unnecessary surgical intervention.
