微创和传统开放后路腰椎椎间融合术治疗腰椎退行性疾病的远期预后

目的探讨微创后路腰椎椎间融合术(MIS-PLIF)和传统开放PLIF对腰椎退行性疾病(LDD)远期疗效及安全性的影响。方法 2011年1月-2014年12月收治LDD患者182例,其中96例采用传统开放PLIF治疗(PLIF组),86例采用MIS-PLIF治疗(MIS-PLIF组)。比较2组腰椎矢状位参数、多裂肌横截面积及萎缩率、融合率、疼痛视觉模拟量表(VAS)评分、日本骨科学会(JOA)评分、Oswestry功能障碍指数(ODI)及术后并发症发生情况,分析多裂肌萎缩率与顽固性腰背痛的相关性。结果 2组术后各随访时间点椎间隙高度恢复值和节段性前凸角恢复值差异均无统计学意义(P > 0.05)。2组术后1年腰椎前凸角恢复值差异无统计学意义(P > 0.05);但术后5年和末次随访时,MIS-PLIF组腰椎前凸角恢复值显著高于PLIF组,差异均有统计学意义(P < 0.05)。MIS-PLIF组术后各随访时间点多裂肌横截面积大于PLIF组,多裂肌萎缩率低于PLIF组,差异均有统计学意义(P < 0.05)。2组术后随访6个月融合率差异无统计学意义(P > 0.05)。2组术后各随访时间点下肢痛VAS评分差异无统计学意义(P > 0.05);MIS-PLIF组术后各随访时间点腰痛VAS评分、JOA评分及ODI均优于PLIF组,差异有统计学意义(P < 0.05)。MIS-PLIF组顽固性腰背痛发生率显著低于PLIF组,差异有统计学意义(P < 0.05)。合并顽固性腰背痛患者多裂肌萎缩率高于未合并顽固性腰背痛的患者,差异有统计学意义(P < 0.05)。结论术后多裂肌萎缩可能是导致顽固性腰背痛的重要原因,相较于传统开放PLIF,MIS-PLIF治疗LDD能够更有效地保持腰椎生理曲度,改善肢体活动功能,降低多裂肌萎缩程度,有助于避免顽固性腰背痛的发生。     

续筋接骨方治疗骨折临床观察

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.

目的 探讨脊髓损伤患者及其配偶二元应对体验,为开展针对性的干预对策提供参考依据。 方法 采用目的抽样法,选取2020年4月—2021年3月入住安徽省某三级甲等综合医院脊柱外科的脊髓损伤患者12例及其配偶12名进行半结构化访谈,采用Colaizzi 7步分析法进行资料归纳并提炼主题。 结果 基于二元应对系统交互模型归纳出积极应对（共同面对、一致的疾病信念、转变沟通态度）、消极应对（适应困难、过度的保护行为、回避或冲突）、困难与挑战（亲密感丧失、寻求外部支持、构建新常态）共3个主题和9个亚主题。结论 脊髓损伤患者及其配偶积极应对与消极应对并存。医护人员需重视对患者及其配偶积极二元应对的引导,重点开展以夫妻为中心的应对干预,使其能更好地面对疾病,改善临床结局。     

A comprehensive 3D CT based classification of intertrochanteric fracture

IntroductionDespite advancements in surgical techniques complications like implant failure is very common after the fixation of intertrochanteric fractures. Classifying these complex fractures based on plain radiographs underestimates the complexity of these fractures which in turn leads to complications. We propose a comprehensive classification of the intertrochanteric fractures based on 3D Non Contrast Computed Tomography (3D NCCT) scan.Material and methodsA total of 102 patients (51 males and 51 females) with intertrochanteric fractures were included in this study conducted over a time period of 22 months in a Tertiary care center in North India. NCCT proximal femur of the intertrochanteric fracture patients was done to formulate a new CT classification system and classify all fractures. Intra and inter-observer reliability was tested using kappa variance.ResultsNew classification system was proposed which included 3 main and a total of 6 groups. All the fractures were classifiable into the new system. Kappa variance of the study showed a good intra and interobserver reliability (0.95 and 0.90) proving clinical agreement of the classification.ConclusionThis new 3D-CT based classification has the advantages of being easy, comprehensible with high intra and inter-observer reliability. This 3DCT based classification can prove to be useful to detect occult intertrochanteric fractures undetectable in plain radiographs as well as choosing the optimum treatment plan.     

Isolated bilateral fibular insufficiency fractures: Case report of an unusual entity

Insufficiency fractures are a type of stress fractures that occur due to physiological stress on weakened bones. These have certain sites of predilection of which an uncommon site is fibular shaft. Isolated bilateral fibular fractures have previously only been reported twice, where the causes were repeated trauma and fatigue fracture. Insufficiency fractures of both fibula in isolation have not previously been reported. We present this case where a young patient presented with these fractures and was found to have vitamin D deficiency on subsequent investigations.
