Abstract:

BACKGROUND: Autogenous morselized bone graft impaction in the single lumbar segment fusion has reliable fusion rate, but there are few reports about the clinical application.
OBJECTIVE: To investigate the feasibility of posterior lumbar interbody fusion with autogenous morselized bone graft impaction in single operation through single incision in low-lumbar tuberculosis.
METHODS: A total of 20 patients with low-lumbar tuberculosis were treated by posterior lumbar interbody fusion with autogenous morselized bone graft impaction. The clinical outcomes were measured according to Frankel classify, as well as treatment effect, fusion rate and deformity correction.
RESULTS AND CONCLUSION: Twenty cases were followed up for 9 to 20 months. The Macnab criteria revealed that 11 patients had excellent result, 8 had good, and 1 had fair, with a excellent and good rate of 95%. The fusion rate was 90%. No complications were observed. Averaging interbody height and Cobb’s angle at the final follow-up were improved compared with preoperation (P < 0.05). Posterior lumbar interbody fusion with autogenous morselized bone graft impaction in single operation through single incision is an effective treatment for low-lumbar tuberculosis which provides satisfactory effect with high interbody fusion rate and low complication rate.
