Localizing Value of Pain Distribution Patterns in Cervical Spondylosis

STUDY DESIGN: Prospective observational study. PURPOSE: To investigate the value of pain distribution in localizing appropriate surgical levels in patients with cervical spondylosis. OVERVIEW OF LITERATURE: Previous studies have investigated the value of pain drawings in its correlation with various features in degenerative spine diseases including surgical outcome, magnetic resonance imaging findings, discographic study, and psychogenic issues. However, there is no previous study on the value of pain drawings in identifying symptomatic levels for the surgery in cervical spondylosis. METHODS: The study collected data from patients with cervical spondylosis who underwent surgical treatment between August 2009 and July 2012. Pain diagrams drawn separately by each patient and physician were collected. Pain distribution patterns among various levels of surgery were analyzed by the chi-square test. Agreement between different pairs of data, including pain diagrams drawn by each patient and physician, intra-examiner agreement on interpretation of pain diagrams, inter-examiner agreement on interpretation of pain diagrams, interpretation of pain diagram by examiners and actual surgery, was analyzed by Kappa statistics. RESULTS: The study group consisted of 19 men and 28 women with an average age of 55.2 years. Average duration of symptoms was 16.8 months. There was no difference in the pain distribution pattern at any level of surgery. The agreement between pain diagram drawn by each patient and physician was moderate. Intra-examiner agreement was moderate. There was slight agreement of inter-examiners, examiners versus actual surgery. CONCLUSIONS: Pain distribution pattern by itself has limited value in identifying surgical levels in patients with cervical spondylosis.

A Levering Technique for Open Reduction of Traumatic Unilateral Locked Facets of Cervical Spine: Technical Note

Reduction of traumatic unilateral locked facets of the cervical spine can be accomplished by closed or open means. If closed reduction is unsuccessful, then open reduction is indicated. The previously described techniques of open reduction of a unilateral locked facets of the cervical spine in the literature included drilling facet, forceful manipulation or using special equipment. We describe a reduction technique that uses a basic spinal curette, in a forceless manner, and it does not need facet drilling. We have successfully used this technique in 5 consecutive patients with unilateral locked facets. There have been no complications related to this technique.
