Abstract：Objective To explore the effects of posterior lumbar interbody fusion ( PLIF ) and polymethylmethacrylate ( PMMA ) for degenerative lumbar spondylolisthesis combined with vertebral fractures. Methods 17 patients with degenerative lumbar spondylolisthesis combined with vertebral compression fractures underwent the surgical treatment of PLIF and PMMA in our hospital from July 2007 to March 2011, whose clinical and imaging data were retrospectively analyzed. All the patients complained of low back pain with or without nerve root irritation of lower limbs. The Magnetic Resonance Imaging ( MRI ) showed high signal on T2-weighted images and of the Software for Tomographic Image Reconstruction ( STIR ) sequence. The surgery time, blood loss, complications, cement amount of the patients were recorded. The Taillard index was used to evaluate the spondylolisthesis degree and the postoperative reduction, and the Visual Analogue Scale ( VAS ) to assess the degree of low back pain before and after the operation.Results All the patients were followed up for more than 1 year. The mean cement amount was ( 4.2±0.7 ) ml, the mean operation time was ( 167±28 ) min, and the mean intraoperative blood loss was ( 708± 45 ) ml. The VAS score of low back pain was improved to ( 4.6±0.2 ) points at the 1st year after the operation, and the mean Taillard index was ( 17.6±1.8 ) % and ( 8.2±1.3 ) % preoperatively and postoperatively. The reduction rare of spondylolisthesis was 53.4%. No severe leakage of bone cement or neurovascular complications occurred in all the patients. Bony fusion was achieved, and no complications such as the displacement of the cage or the loose, breakage or slipping out of screws were found in the latest follow-up.Conclusions It is an effective method of PLIF and PMMA in the treatment of degenerative lumbar spondylolisthesis combined with vertebral fractures, with good curative effects. The holding force of pedicle screws is increased after the usage of PMMA, and the nerve root irritation is improved by the complete decompression and interbody fusion.
