The influence of gender on postoperative PROMIS physical function outcomes following minimally invasive transforaminal lumbar interbody fusion

PurposeOur aim is to examine the gender performance of Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF) scores among patients undergoing minimally invasive transforaminal lumbar fusion (MIS TLIF).MethodsA prospectively collected surgical dataset was retrospectively assessed for eligible patients from March 2015–June 2019. We included patients if they underwent primary MIS TLIF procedures on one or two vertebral levels. We collected baseline demographics, perioperative characteristics, and PROMIS-PF scores for each subject at pre and postoperative timepoints (e.g., 6-weeks, 3-months, 6-months, and 1-year). Chi-squared analyses were utilized to assess categorical variables and a Student’s t-tests analyzed continuous variables. A linear regression was used to analyze PROMIS-PF scores from baseline through all postoperative time points. Finally, we evaluated the PROMIS PF achievement of minimal clinically important difference (MCID) among gender.Results192 patients were included: 77 were females and 115 were males. No significant differences were observed among gender subgroups for PROMIS-PF scores at pre- or postoperative evaluations. Compared to males, females experienced significantly greater postoperative improvement with PROMIS-PF scores at the 3-month assessments, though no significant gender differences were observed during later follow-up evaluations at 6-months or one year. Females were observed to have significant PROMIS-PF score improvement from their preoperative evaluation to each postoperative score. Males were assessed to have statistically significant postoperative (e.g., at 3-months, 6-months, and 1-year) PROMIS-PF score improvement from their preoperative PROMIS-PF scores. There were no significant differences among gender in achieving MCID at any postoperative time interval.ConclusionAmong gender, we observed no statistically significant difference in PROMIS-PF scores during the pre- or postoperative evaluations. Additionally, with no difference in the rate of achieving PROMIS-PF MCID postoperatively, this study established that both genders should experience similar functional outcomes following MIS TLIF.     

不同植骨融合术治疗腰椎滑脱症的疗效分析

目的比较腰椎后外侧融合术(PLF)、腰椎后路椎间植骨融合术(PLIF)及腰椎经椎间孔椎间植骨融合术(TLIF)治疗腰椎滑脱症的临床效果。方法 118例腰椎滑脱患者,均予以椎弓根螺钉复位固定后行植骨融合术,其中行腰椎后外侧融合术36例(A组),腰椎后路椎间植骨融合术42例(B组),腰椎经椎间孔椎间植骨融合术40例(C组)。回顾性分析3组患者临床资料,比较3种植骨融合术的融合率及临床症状的改善情况。结果 C组的手术时间、术中出血量均明显低于A组和B组(P<0.05),但C组的植骨融合率明显高于A组和B组(P<0.05);A、B、C组的优良率分别为77.8%、83.3%和95.0%,3组间比较无统计学差异(P>0.05)。结论联合椎弓根螺钉系统复位固定,有利于提高植骨融合率,减少并发症;腰椎经椎间孔椎间植骨融合术具有手术时间短、出血量少、椎间融合面积大、融合率高等优点,值得临床推广应用。

目的　设计一种新型的“肾形”n-HA/PA66腰椎间融合器(cage),通过三维有限元分析,研究其在经椎间孔腰椎椎间融合术(TLIF)中的生物力学特性。 方法 建立正常人体L3-L5节段三维模型,模拟经椎间孔腰椎椎间融合术,采用有限元分析方法进行应力分析,比较肾型与子弹头型n-HA/PA66腰椎间融合器应力分布的差异。 结果　在前屈、后伸、左右旋转工况下两种不同cage的TLIF手术模型对比,子弹头型cage最大应力分别为32.8、32.8、31.4、31.3、32.8、34.2 MPa,肾型cage最大应力分别为13.2、11.4、10.9、10.1、11.7、11.1 MPa;而且肾型cage应力集中区域小于子弹头型cage。 结论　肾型n-HA/PA66腰椎间融合器固定的椎体应力分布小而均匀,理论上可有效降低cage沉降率。     

Transforaminal lumbar interbody fusion (TLIF) versus posterior lumbar interbody fusion (PLIF) in lumbar spondylolisthesis: a systematic review and meta-analysis

Background Context

Transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF) are both frequently used as a surgical treatment for lumbar spondylolisthesis. Because of the unilateral transforaminal route to the intervertebral space used in TLIF, as opposed to the bilateral route used in PLIF, TLIF could be associated with fewer complications, shorter duration of surgery, and less blood loss, whereas the effectiveness of both techniques on back or leg pain is equal.

TLIF技术治疗腰椎滑脱的疗效分析

目的探讨经椎间孔椎体间融合（transforaminal lumbar interbody fusion,TLIF）治疗腰椎滑脱的疗效。方法2004年8月至2007年2月应用TLIF技术治疗Ⅰ～Ⅱ度腰椎滑脱患者39例,男25例,女14例;年龄34～65岁,平均53岁。将19例使用cage融合器患者分为A组,20例采用自体骨为B组。采用Nakai评分标准评价治疗效果。通过腰椎侧位片测量术前、术后2周及术后6个月椎体滑移距离、腰椎前凸角、椎间隙高度,判断骨融合情况。结果随访12～28个月。A组优9例,良7例,可3例,优良率为84.21%。B组优10例,良7例,可2例,差1例,优良率为85%。两组间优良率无统计学差异（方差分析,P〉0.05）。椎体滑移距离、腰椎生理前凸角及椎间隙高度术前与术后2周比较,差异均有统计学意义（P〈0.05）;术后2周与术后6个月比较,差异均无统计学意义（P〉0.05）。患者术后5～11个月植骨均融合,平均7.3个月。内固定材料无松动、断裂,Cage融合器位置及形态正常。结论TLIF技术治疗腰椎滑脱能够明显缓解患者症状及改善相关功能障碍,提高脊柱的融合率,是治疗腰椎滑脱症的一种理想方法。
