Objective To evaluate the cl inical effect of local autogenous bone chips extended with allogeneic bone grafts in the posterolateral lumbar fusion. Methods From March 2005 to April 2007, 22 cases which underwent posterolateral
lumbar fusion with allograft bone mixed with local autograft bone were analyzed retrospectively. The postoperative temperature, drainage flow and heal ing time of the incision were analyzed; postoperative lumbar pain was evaluated by visual analog scale (VAS) and JOA score; the postoperative efficacy was assessed by MacNab criteria and Oswestry disabil ity index (ODI); the fusion rate was defined by Jorgenson fusion criteria. Results All cases were followed up for 17-35 months with an average of 21 months, the wound all healed by first intention; no red swell ing, exudation and infection occurred. The excellent and good rate was 81.8% for JOA score (excellent in 4 cases, good in 14 cases, fair in 4 cases), 77.3% for MacNab criteria (excellent in 4 cases, good in 13 cases, fair in 5 cases) and 90.9% for ODI index (excellent in 3 cases, good in 17 cases, fair in 2 cases). The postoperative X-ray fusion rate within 1 year was 90.9%. Conclusion Allograft bone mixed with local autograft bone can achieve good efficacy and fusion rate in posterolateral lumbar fusion.
