Abstract:
Objective To observe the clinical effect of GSS pedicle screw system and interbody autogenous iliac bone graft fusion in the treatment of lumbar spondylolisthesis.Methods Twenty-one lumbar spondylolisthesis patients was treated by GSS pedicle screw system and interbody autogenous iliac bone graft fusion.Followed up and analyzed the clinical therapeutic efficacy,rate of detachment and reduction,interbody fusion and intervertebral height change.Results Postoperative rate of detachment and reduction had significant difference compared with preoperative [(6.41 ± 6.90)％ vs.(36.75 ± 7.11)％,(86.75 ± 24.40)％ vs.0](q =19.60,19.72,P＜ 0.01).Final follow-up rate of detachment and reduction had no significant difference compared with postoperative (q =0.70,0.96,P ＞ 0.05).Postoperative intervertebral height had significant difference compared with preoperative[L4-5:(7.6 ± 1.3) mm vs.(5.2 ± 0.8) mm; L5S1:(8.4 ± 2.2) mm vs.(6.5 ± 1.5) mm] (q =6.64,3.83,P ＜ 0.01).Final follow-up intervertebral height had no significant difference compared with postoperative (q =2.48,2.42,P ＞ 0.05).All patients were bony fusion,rate of fusion was 100.00％(21/21).In accordance with the Japan institute of orthopaedics (JOA) low back pain surgery standards,the scores of 6 months,1 year,2 years significant increased compared with preoperative [(20.50 ± 3.83),(23.58 ± 3.60),(24.91 ± 2.90) scores vs.(9.67 ± 4.45) scores] (F =71.92,q =13.28,17.06,18.69,P ＜ 0.01).No complication of internal fixation for fracture or looseness.Conclusions The clinical effect of GSS pedicle screw system and interbody autogenous iliac bone graft fusion in the treatment of lumbar spondylolisthesis is good.It has advantages of bone graft area and bone mass,rate of fusion.It is one of better methods in the treatment of lumbar spondylolisthesis.
