To observe the effect of posterior lumbar intervertebral fusion (PLIF) device and a novel transpedical screw system for the treatment of lumbar spondylolisthesis.
Thirty-three patients with lumbar spondylolisthesis were treated with PLIF device for intervertebral fusion after total laminectomy and internal fixation with the novel transpedical screw system.
The patients were followed up for 6 to 36 months with an average of 18.6 months. Nerve injuries and infection of the incisions occurred in none of the cases postoperatively, and no cases exhibited PLIF device displacement or transpedical screw loosening or breaking, nor were other complications seen in this group. The clinical results were excellent in 21 cases, good in 10 cases, and acceptable in 2 cases according to the standard of Brantigan.
PLIF device and new transpedical screw system constitute good treatment modalities for lumbar spondylolisthesis, with such merits as full decompression of the spinal canal, good restoration of the vertebral body, immediate pain relief and reliable fixation of the vertebral body to allow early force loading postoperatively, and are therefore suitable for treating lumbar spondylolisthesis.
观察后路腰椎椎间融合器（PLIF）及新型椎弓根螺钉系统治疗腰椎滑脱症的效果。
33例腰椎滑脱症患者行全椎板切除术后，采用PLIF装置行椎间融合，并使用新型椎弓根螺钉系统进行内固定。
患者随访6至36个月，平均18.6个月。术后无一例发生神经损伤及切口感染，无PLIF装置移位、椎弓根螺钉松动或断裂，该组亦未见其他并发症。根据Brantigan标准，临床结果优21例，良10例，可2例。
PLIF装置及新型椎弓根螺钉系统是治疗腰椎滑脱症的良好方法，具有椎管充分减压、椎体良好复位、即刻缓解疼痛、椎体固定可靠、术后可早期负重等优点，适合治疗腰椎滑脱症。
