TUESDAY, Aug. 18 (HealthDay News) -- The fusion rate of anterior cervical diskectomy and fusion with allograft patella to relieve cervical radiculopathy and myelopathy is 86 percent, similar to other allografts, according to a study in the August issue of the Journal of Spinal Disorders & Techniques.
Wade K. Jensen, M.D., from the University of Wisconsin in Madison, and colleagues retrospectively assessed the fusion rates of single and multilevel anterior cervical diskectomy and fusion with allograft patella in 136 patients with 179 levels (98 single, 81 multilevel).
During an average follow-up of 19.3 months, the researchers found that the fusion rate was 86 percent by level (87 percent single level, 85 percent multilevel). The overall revision surgery rate for symptomatic nonunions was 8 percent. Fusion rates were similar for static and dynamic plates. Clinical outcome was classified as good or excellent in 85 percent of patients and was strongly associated with fusion success.
"Patella allograft after anterior cervical fusion had a fusion rate of 86 percent, which is inferior to autograft historical controls, but similar to other allografts reported for anterior cervical decompression and fusion," Jensen and colleagues conclude.
