Risk Factor Analysis of Facet Fusion Following Cervical Lateral Mass Screw Fixation with a Minimum 1-Year Follow-up: Assessment of Maximal Insertional Screw Torque and Incidence of Loosening

Posterior stabilization is a common surgical procedure, which aims for rigid stabilization by facet fusion. Facet non-union has a potential risk of the screw loosening and malalignment. Although some authors have reported the influencing factors about screw loosening in the lumbar spine, there are few reports about the risk factor contributing to the facet non-union in the cervical spine. In all, 22 patients (78 facets and 122 screws) with degenerative cervical kyphosis or spondylolisthesis who underwent decompression and lateral mass screw (LMS) fixation were analyzed. Age, gender, smoking, bone mineral density (BMD), the degree of facet decortication with bone packing, and screw loosening were investigated as risk factors contributing to the facet non-union at each segmental fused level. Facet fusion rate was 85.9% (67/78 facets) and the incidence of loosening was 4.9% (6/122 screws, 4 patients). Insufficient facet decortication with bone packing is a significant risk factor of facet non-union (p <0.05, odds ratio: 26.5). All six loosened screws were associated with bony non-union of the facet and were located in the uppermost or lowermost vertebrae. Comparing loosened screws and stable screws, the average maximal insertional screw torque (MIT) was 9.8 cNm and 39.5 cNm, respectively (p <0.05). Additionally, the length of the stable screws was significantly longer versus the loosened screws (p <0.05). Lower MIT and shorter screw length located near the ends of the lateral mass may predict loosening, which can lead to facet non-union. Sufficient facet decortication with bone packing is one of the important factors contributing to the facet fusion.     

Prevalence of Risk Factors for Adverse Spinopelvic Mobility Among Patients Undergoing Total Hip Arthroplasty

BackgroundPatients with adverse spinopelvic mobility have higher complication rates following total hip arthroplasty (THA). Risk factors include a stiff lumbar spine, standing posterior pelvic tilt ≤ ?10°, and a severe sagittal spinal deformity (pelvic incidence minus lumbar lordosis mismatch ≥20°). The purpose of this study is to define the spinopelvic risk factors and quantify the prevalence of risk factors for pathologic spinopelvic mobility.MethodsA retrospective cohort analysis from January 2014 to February 2020 was performed on a multicenter series of 9414 primary THAs by 168 surgeons, all with preoperative spinopelvic measurements in the supine, standing, and flex-seated positions. All patients were included. The prevalence of adverse spinopelvic mobility and frequency of each spinopelvic risk factor was calculated.ResultsThe cohort was 52% female, 48% male, with an average age of 65 years. Thirteen percent of patients exhibited adverse spinopelvic mobility and 17% had one or more of the 3 risk factors. Adverse mobility was found in 35% of patients with at least 1 risk factor, 47% with at least 2 risk factors, and 57% with all 3 risk factors.ConclusionForty-six percent of patients had spinopelvic pathology driven by one or more of the risk factors. Number of risk factors present and risk of adverse spinopelvic mobility were positively correlated, with 57% of patients with all 3 risk factors exhibiting adverse spinopelvic mobility. Although this study defines the prevalence of these risk factors in this highly selected cohort, it does not report incidence in a general THA population.Level of EvidencePrognostic Level IV.

经椎间孔入路全内镜下腰椎椎体间融合术（full endoscopic transforaminal lumbar interbody fusion）近年来在微创脊柱外科领域获得广泛应用,本文简要介绍该术式的发展历史、技术要点、适应证、疗效以及并发症。笔者认为经椎间孔入路全内镜下腰椎椎体间融合术具有与传统手术同样的临床效果,并且能够有效减少组织损伤和术中出血、降低术后腰背痛的发生率、缩短术后下床活动时间及平均住院日,但仍需完善远期随访,以进一步评估该术式的有效性和安全性。     

多节段前外侧入路腰椎椎间融合联合后路内固定术治疗腰椎退行性侧凸伴矢状面失衡的疗效分析

【摘要】 目的：探讨多节段前外侧入路腰椎椎间融合（oblique lumbar interbody fusion,OLIF）联合后路内固定治疗腰椎退行性侧凸伴脊柱矢状面失平衡的效果。方法：回顾性分析2017年9月～2020年4月于我院就诊并接受多节段OLIF联合后路内固定治疗的17例腰椎退行性侧凸伴脊柱矢状面失平衡患者,男3例,女14例;年龄55～81岁（67.8±6.3岁）;随访时间13～39个月（25.9±7.6个月）。在术前、术后与末次随访时的全脊柱X线片测量脊柱冠状面及矢状面相关参数,包括：腰椎侧凸Cobb角、C7铅垂线-骶骨中垂线距离（C7 plumb line-center sacral vertical line,C7PL-CSVL）、胸椎后凸角（thoracic kyphosis,TK）、胸腰段后凸角（thoracolumbar kyphosis,TLK）、腰椎前凸角（lumbar lordosis,LL）、腰椎前凸分布指数（lordosis distribution index,LDI）、脊柱矢状面垂直轴（sagittal vertical axis,SVA）、脊柱骶骨角（spino-sacral angle,SSA）、躯干整体倾斜角（global tilt,GT）、GAP评分（Global Alignment and Proportion score）、骨盆入射角（pelvic incidence,PI）、骨盆倾斜角（pelvic tilt, PT）、骶骨倾斜角（sacral slope,SS）。记录术前、术后与末次随访时的Oswestry功能障碍指数（Oswestry disability index,ODI）、日本骨科协会（Japanese Orthopaedic Association,JOA）评分、腰部和下肢疼痛视觉模拟（visual analogue scale,VAS）评分。对术前、术后和末次随访时的影像学和临床指标进行统计学分析。结果：17例患者均顺利完成手术,手术时间120～480min（327.4±85.4min）,出血量50～1100ml（504.7±275.1ml）,融合节段3～8个（3.8±1.2个）。1例患者术后左侧大腿外侧腹股沟区感觉减退,给予营养神经药物后20d症状缓解;1例患者术中发生椎体终板骨折,调整融合器置入路径避开骨折部位,同时一期附加后路椎弓根螺钉内固定,随访未发现融合器进一步沉降。术后和末次随访时的腰椎侧凸Cobb角、C7PL-CSVL、TK、TLK、LL、LDI、GT、GAP评分、PT、SS与术前比较均有显著性差异（P＜0.05）,腰椎矢状面平衡相关参数均获得改善;术后与末次随访时比较均无显著性差异（P>0.05）。术后和末次随访时的ODI、JOA评分、腰部VAS和下肢VAS评分与术前比较均有显著性改善（P＜0.05）,末次随访时进一步改善,与术后比较差异均有显著性（P＜0.05）。结论：多节段OLIF联合后路内固定术可以有效缓解腰椎退行性侧凸患者的症状,同时矫正脊柱三维畸形、重建矢状面和冠状面平衡,提高患者生活质量。
