Myelography as a Stand-Alone Diagnostic Procedure for Degenerative Spine Disease in Developing Nations

The use of “stand-alone” contrast myelography (i.e., without computed tomography) has a proven track record in developing nations where few patients have access to magnetic resonance imaging, whether on the basis of prohibitive cost or the absence of such a modality altogether. To substantiate the author's 12-year experience with more than 300 myelograms performed in 16 different countries (plus some 1500 studies during 30 years of practice in the United States), a prospective pilot study was undertaken over 1 month in a community-based neurosurgical setting in western Kenya.Forty patients underwent cervical or lumbar myelography at Tenwek Hospital under the auspices of the Neurosurgery Training Program for East, Central, and South Africa (NSTP-ECSA) following failure of conservative measures to treat spine-related pathology. Thirty-five of the forty patients (88%) came to definitive surgery on the basis of a positive study that correlated with their clinical history and physical examination. There were no significant complications from the procedures, and no false-positive studies, with virtually all patients returning to normal activity and/or gainful employment within 3 weeks of their surgery.Myelography as a stand-alone diagnostic procedure is a sensitive, specific, and cost-effective means of diagnosing symptomatic degenerative spine disorders. Accordingly, its use should be encouraged at every NSTP-ECSA training site to address such ubiquitous pathology.
