Risk Factors and Cup Protrusion Thresholds for Symptomatic Iliopsoas Impingement After Total Hip Arthroplasty: A Retrospective Case-Control Study

Background

Groin pain and functional limitations may occur after total hip arthroplasty (THA) due to iliopsoas impingement (IPI). We aimed to determine the risk factors and thresholds of cup protrusion for symptomatic IPI.

Severe skeletal bimaxillary protrusion treated with micro-implants and a self-made four-curvature torquing auxiliary: A case report

BACKGROUNDBimaxillary protrusion is a clinically common dentofacial deformity, particularly among Chinese patients. This kind of malformation can severely affect facial esthetics and, even in mild cases, is difficult to correct without surgery. Unfortunately, many patients abandon treatment because of fear of surgery. Here, we describe a case of severe skeletal bimaxillary protrusion treated with nonsurgical orthodontic treatments, highlighting an alternative treatment option.CASE SUMMARYA 31-year-old woman wished to address a severe protrusion profile (approximately 8 mm overbite) and gummy smile. Cephalometric analysis and superimposition showed a severe skeletal class II pattern with a mandibular retrusion, and proclined and protrusive mandibular incisors. Panoramic radiograph showed a missing mandibular right third molar. A diagnosis of severe bimaxillary dentoalveolar protrusion was made. Taking into account the patient’s fear of orthognathic surgery, she accepted the proposed alternative treatment using micro-implants and a self-made four-curvature torquing auxiliary. The treatment allowed for maximal en masse anterior tooth retraction, proper relocation of incisors, and alleviation of the skeletal class II pattern. Esthetically, the patient’s lip protrusion was significantly decreased as was the overjet (from 10.5 mm to 1.8 mm), and the results remained stable throughout the 2-year follow-up.CONCLUSIONNonsurgical treatment using micro-implants and a four-curvature torquing auxiliary may benefit severe cases of skeletal bimaxillary protrusion in adults.     

综合治疗腰椎间盘突出症的疗效分析

关节松动术治疗腰椎间盘突出症临床疗效对照研究

目的：对比关节松动术配合腰椎牵引与理疗配合牵引治疗腰椎间盘突出症的临床疗效。方法：治疗组（44例）采用关节松动术，使用ATA－IID型自动牵引床，取仰卧位持续牵引治疗；对照组（44例）采用超短波、中频电疗、牵治疗，治疗结束后两组病例进行评定。结果：治疗组优于对照组（P＜0．01）。结论：关节松动术治疗腰椎间盘突出症，疗程短、显效快、疗效好。     

腰三针配合手法复位治疗腰椎间盘突出症的疗效及肌电图分析

目的：探讨腰三针配合手法复位治疗腰椎间盘突出症的作用机理。方法：腰椎间盘突出症患者60例均采用腰三针配合手法复位治疗，治疗前后进行肌电图检测并分析。结果；经过20次治疗后。60例患者临床治愈35例（58．3％），总有效率为95．0％。肌电图显示腓总神经及胫神经传导速度与治疗前比较显著增高，接近正常值，并能使延长的神经远端潜伏期显著缩短。结论：腰三针配合手法复位治疗腰椎间盘突出症可显著改善患者的临床症状。提高神经传导速度，促进患肢功能的恢复。     

用体征计分评价腰椎间盘突出症

对12例腰椎间盘突出症患者进行综合康复治疗后,应用体征计分与Fairbank JC的腰痛病情计分分别对其疗效进行了量化评价,结果2种方法评价效果相近,故体征计分可以作为腰椎间盘突出症的功能评定依据和疗效评价的标准之一。     

腰神经根受压对下肢肌力影响的定量化检查

为了了解腰脊神经根受压后对肌力影响的程度，本文应用Ｃｙｂｅｘ一６０００型等速肌力测试系统对１０１例门诊病人的二侧踝屈、伸肌群进行测量，测出峰力矩、一次作功、平均功率、力矩加速能、多次总作功、耐力以及踝屈伸主动肌与桔抗肌的肌力比值。发现患侧除耐力与健侧差别不大外，其余能力大多低于健侧２０～３０％，患侧踝屈伸肌力和作功能力明显低于健侧，其发生率约为７０～８０％。     

经阴道入路治疗直肠前突64例临床分析

目的探讨治疗直肠前凸的手术方法。方法对64例直肠前凸患者应用经阴道入路治疗,观察其术后效果。结果本组痊愈53例（82.8%）,好转8例（12.5%）,无效3例（4.7%）。疗程18～26天,平均23天。术后随访6～24个月,无并发症及后遗症。结论经阴道入路治疗直肠前突方法简单,效果明确。     

腰椎间盘突出症血瘀证与TGF-β1-509C/T基因多态性及腰椎负荷强度的关联研究

目的 探讨腰椎间盘突出症血瘀证与转化生长因子β1（TGF-β1）-509C/T基因多态性及腰椎负荷强度的关联性.方法 筛选符合既定相关标准的广西汉族腰椎间盘突出症患者120例,分为血瘀证组60例与非血瘀证组60例,进行TGF-β1-509C/T基因多态性检测,并观测患者的腰椎负荷强度,分析TGF-β1-509C/T基因多态性与腰椎负荷强度的交互作用与腰椎间盘突出症中医证型的关联性.结果 经非条件Logistic回归Forward（LR）法分析显示广西汉族重度腰椎负荷强度者患腰椎间盘突出症血瘀证的风险是轻中度腰椎负荷强度者的3.977倍（95%CI：1.012～3.801）（P〈0.05）,TGF-β1基因-509C/T多态性与重度腰椎负荷强度的累积暴露发生腰椎间盘突出症血瘀证的风险是其中某单一因素的5.365倍（95%CI：1.086～2.703）（P〈0.05）.结论 重度腰椎负荷强度是广西汉族腰椎间盘突出症患者血瘀证的潜在危险因素之一,TGF-β1基因-509位点CT基因型与重度腰椎负荷的交互作用可增加腰椎间盘突出症血瘀型发生的可能性.     

前列腺突入膀胱距离及逼尿肌厚度与膀胱出口梗阻的关系探讨

目的探讨前列腺突入膀胱距离(intravesical prostatic protrusion,IPP)及逼尿肌厚度(de-strusor wall thickness,DWT)与良性前列腺增生(benign prostatic hyperplasia,BPH)所致膀胱出口梗阻(bladder outlet obstruction,BOO)的关系,旨在寻找一种简单、非侵入性诊断的方法。方法选择前列腺增生有下尿路症状患者200例,予经腹超声检查及尿流动力学检查,测量参数包括:IPP、DWT、残余尿量(post-void residual urine,PVR)、前列腺体积(prostate volume,PV)、尿流动力学Schaefer分级;对数据进行统计分析并绘制相应ROC曲线。结果 IPP、DWT、PV与Schaefer分级相关[相关系数(r)分别为0.73、0.56、0.23,P值均<0.01];PVR与Schaefer分级无关;IPP、DWT、PV的ROC曲线下面积分别为0.80、0.84、0.60。结论经腹超声测量DWT、IPP可以预测前列腺增生患者BOO程度,是一种简单、无创、有效的评估方法。
