Surgical treatment of spondylolisthesis combined with symptomatic intervertebral disk herniation of consecutive segments

Abstract

Objective To investigate the surgical treatment of spondylolisthesis combined with symptomatic intervertebral disk herniation of close together segments and evaluate the operative effect. Method From January 2001 to January 2009, 60 cases of spondylolisthesis combined with symptomatic intervertebral disk herniation of consecutive segments treated by posterior vertebral body reposition, excision of intervertebral disk herniation, interverbral implanted bone fusion and pedicle screw internal fixation, evaluated and compared the preoperative and postoperative effects. Results In 3 days postoperative, 55 cases had hemilateral or contralateral neuropathic pain or numbness, 9 cases had hemilateral or contralateral neuropathic pain or numbness 3 months postoperative, 2 cases had hemilateral neuropathic pain 1.5 years postoperative. Nobody had neuropathic pain after 2 years postoperative,but 7 cases had low back pain sometimes. The surface of the osteotomy infused after 1.5 years. There wasn't interplantation's clinch and breakage. Oswestry score 1 year postoperative average (26.07 ± 9.36) scores,preoperative average(55.34 ± 11.05) scores, there was statistical significance between them (P < 0.05). Conclusion Posterior vertebral body reposition, excision of intervertebral disk hermina, interverbral implanted bone fusion and pedicle screw internal fixation is an effective surgical method to treat spondylolisthesis combined with symptomatic intervertebral disk herniation of consecutive segments, it has satisfied clinical effect.
