THURSDAY, May 24 (HealthDay News) -- Posterior cervical lateral mass screw fixation and fusion can be successfully used to manage patients with symptomatic cervical pseudarthrosis that develops after anterior cervical discectomy and fusion, according to a study published in the May issue of the Journal of Spinal Disorders & Techniques.
Hong Liu, M.D., of the Peking University First Hospital in Beijing, and colleagues conducted a retrospective clinical cohort study involving 38 consecutive patients who underwent posterior cervical lateral mass screw/rod fixation and fusion to treat pseudarthrosis of anterior cervical fusion; the authors sought to determine the efficacy of this technique. Patients were followed for an average of 28 months. Clinical results were rated on the basis of clinical examination, questionnaires, and imaging scans, and were classified according to Zdeblick criteria as excellent, good, fair, or poor.
The researchers found that, at the final follow-up, all patients achieved a solid radiographic fusion. Ten patients experienced an excellent clinical result, 22 achieved a good clinical outcome, and six achieved a fair clinical outcome. No patient exhibited a poor clinical result.
"In summary, patients diagnosed with symptomatic cervical pseudarthrosis after anterior cervical discectomy and fusion may be managed successfully with posterior lateral mass screw/rod fixation and fusion," the authors write.
