Abstract:
[Objective] To explore the effect of B-Twin intervertebral cage for degenerative lumbar instability with posterior mini-incision.[Methods]Thirteen patients(13 disc-spaces)treated with B-Twin intervertebral cage in combination with autogenous morselized bone were enrolled in this study.Among the patients,11 had degenerative instability in L4、5 and 2 in L5S1.Patients were graded postoperatively with JOA scoring system.[Results]The lower back pain and leg pain were relieved significantly in all patients after operation.All were followed-up for an average of 16.2 months,and the JOA scores inproved from 4.2 preoperatively to 14.4 at the final follow-up.The good to excelleat rate was 92.3%.The bony fusions presented in an average of 19.8 weeks postoperatively by CT scan.Neither cage loosening nor neurological injury was found.[Conclusion]B-Twin intervertebral cage combined with autogenous morselized bone insertion for lumbar degenerative instability by posterior mini-incision operation is a good technique,which could achieve satisfactory clinical results with less injury.
