Objective To report the clinical characteristics and surgical procedures for calcified protrusion of the lumbar intervertebral disc. [WT5”HZ]Methods [WT5”BZ]During August, 1991 and May, 1999, 53 cases of calcified protrusion of the lumbar intervertebral disc confirmed by CT received operations. Calcified tissues were resected with herniated nuclei by enlarged fenestration or hemi-laminectomy. [WT5”HZ]Results[WT5”BZ] In 49 cases with a 6～60 month follow-up,symptoms disappeared completely, and 45 resumed their normal activities and 4 had mild numbness or pain in the lower limb. Excellent and good results were achieved in 91.84% of the patients. [WT5”HZ]Conclusion[WT5”BZ] Calcified tissues which lead to compression of the cord or neural roots should be resected together with herniated nuclei,and enlarged fenestration or hemi-laminectomy provides a satisfactory exposure and decompression during the operation.
