Use Of OsteoSet Artificial Bone Combined With Internal Fixation In Spinal Fusion For The Treatment Of Spinal Tuberculosis-clinical Primary Report

ObjectiveTo assess the reliability, feasibility and superiority of Osteo Set artificial bone and autogenic bone grafting combined with internal fixation after radical debridement in the treatment of spinal tuberculosis.MethodsA before-after study was in different group patients. Experimental group: 20 cases, radical debridement, OsteoSet artificial bone and autogeneic bone grafting combined with internal fixation; control group: 20 cases, radical debridement, bone autograft combined with intemal fixation. Radiographs (X-rays and CT scans) were analyzed before operation, immediately after operation, 3 months, 6 months and 12 months after operation to access bony fusion and deformity correction.ResultThe average in-patient days was 19.5d (12-27d.). All the patients acquired satisfactory incision healing without fever. The average WBC account one week after operation was 8.2×10~9. The follow-up period ranged from 12 to 48 months (mean 26 months). There was no recurrence of the disease or loose instrument. The average cobb's angle corrected was 15°. The rate of fusion in experimental group was 40%(8/20) in 3 month after operation, and was 85% (17/20) in 6 month after operation. While in control group it was 10% (2/20) in 3 month after operation and 55% (11/20) in 6 month after operation.ConclusionOsteoSet artificial bone can avoid the complications of donor bone site, and achieve bony fusion earlier than using autogeneic bone alone. The early clinical outcome is satisfying.
