微创单侧经皮PLIF术治疗腰椎退变的近期疗效

目的探讨微创单侧后路椎体间融合术(PLIF)治疗腰椎退变疾病的临床疗效。方法55例单阶段腰椎退变疾病患者采用微创PLIF联合单侧经皮椎弓根螺钉内固定(A组,21例)和传统后正中入路PLIF联合双侧椎弓根螺钉内固定(B组,34例),采用VAS和JOA评分系统比较两组临床疗效。结果全部病例随访3-18个月。与B组比较,A组手术切口短、出血量少、住院时间短(P<0.05);两组术后1周与术后3个月的JOA评分及术后3个月VAS评分比较(P<0.05)。结论微创单侧PLIF术治疗腰椎退变疾患具有切口小、痛苦少、出血少、术后恢复快等优点。

Early clinical efficacy of minimally invasive unilateral PLIF for treating lumbar degenerative diseases

Objective To observe the short-term clinical efficacy of minimally invasive posterior lumbar interbody fusion(PLIF) using a single cage fixed with unilateral percutaneous pedicle screw in treating lumbar degenerative diseases.Methods A total of 55 patients with one level lumbar degenerative disease was treated with minimally invasive unilateral PLIF(group A,21 cases) or with PLIF via conventional posterior median inlet and bilateral pedicle screw fixation(group B,34 cases).Incision size,operation time,blood loss and hospital stay were compared.The short-term clinical efficacy was evaluated with VAS and JOA scores one week and 3 months after surgery.Results All patients were followed up from 3 to 18 months.Compared to group B,the incision was smaller,blood loss was less and hospital stay was shorter in group A(P<0.05).The VAS and JOA scores one week and 3 months after surgery were not significantly different between two groups(P>0.05).ConclusionMinimally invasive unilateral PLIF has the advantages of small incision,little bleeding,short hospital stay and better recovery.
