Application of polyetheretherketone cages and titanium cages combined with pedicle screw fixation operation in lumbar degenerative disease / 局解手术学杂志

ABSTRACT

Objective To explore the clinical efficacy of polyetheretherketone( PEEK) cages and titanium cages combined with pedicle screw fixation operation in treatment of lumbar degenerative disease,and provide reference for clinic. Methods The data of 50 patients with lumbar degenerative disease in our hospital from March 2011 to March 2013 were retrospectively analyzed. All patients were treated with pos-terior decompression,bone graft and transpedicular screw internal fixation,according to the different cages,they were divided into PEEK group and titanium group. The PEEK group with 25 patients used polyetheretherketone cages,and the titanium group with 25 patients used titanium cages. The JOA scores of patient before surgery,1 month,6 months and 1 year after surgery between two groups were recorded and compared. The ROM of fusion levels and adjacent segment of patients before and after operation between two groups were compared. Results There was no statistical significance of difference in JOA score,Oswestry score and fusion rate between two groups(P>0. 05). There were statistical significance of differences intervertebral disc height change between 2 groups(P<0. 05). The ROM of fusion levels and adjacent segment of patients in PEEK group was better than those in titanium group(P<0. 05). Conclusion The polyetheretherketone cages combined with pedicle screw fixation operation have a good effect in the treatment of patients with lumbar degenerative disease,especially in matter of lumbar spinal motion and intervertebral height lost.
