髌周去神经化预防全膝关节置换术后膝前疼痛

目的　依据髌周解剖学特点，探讨全膝关节置换术（total knee arthroplasty，TKA）中应用髌周电灼去神经化的临床效果。 方法　纳入82名诊断为骨性关节炎的患者（91膝），予行双侧或单侧不置换髌骨的TKA，按随机对照原则将病人分为两组，共有41名实验组患者（45膝）在TKA中接受了髌周去神经化处理，41名对照组患者（46膝）未做该处理。手术主刀为同一骨科医师，均使用相同的膝关节假体系统。主要评价项目包括膝关节KSS评分、Western Ontario and McMaster Universities（WOMAC）、Feller髌骨评分及VAS评分。 结果　82名患者术后均获随访，平均随访时间为12个月，两组病人的膝关节KSS评分、WOMAC、Feller髌骨评分及VAS评分均无显著统计学差异（P>0.05）。 结论　在TKA中行髌周电灼去神经化，不能显著改善病人的预后。     

Fetal anterior abdominal wall thickness between gestational diabetes and normal pregnant women

ObjectivesTo compare fetal anterior abdominal wall thickness (AAWT) between women with and without GDM during third trimester and to determine accuracy of AAWT to predict large for gestational age (LGA) infants.Materials and methodsA total of 250 pregnant women, including 125 women with GDM and 125 women without GDM, were enrolled. Tansabdominal ultrasonographic examinations were performed at 28–30, 32–34 and 36–38 weeks. In addition to standard fetal biometries, AAWT was measured. Patient characteristics and ultrasonographic measurements were compared between groups. Sensitivity and specificity of AAWT for identifying LGA were evaluated.ResultsWhile standard fetal biometries were comparable, mean fetal AAWT in GDM women were significantly higher than those without GDM at 28–30 weeks (2.8 ± 0.8 vs. 2.6 ± 0.6, p = 0.006) and 32–34 weeks (4.0 ± 0.9 vs. 3.5 ± 0.8, p = 0.042). LGA infants had significantly higher fetal AAWT at each time point only in GDM women. Using cut off values of AAWT of ≥2.0, 3.0, and 4.0 mm at 28–30, 32–34, and 36–38 weeks, sensitivity for LGA diagnosis in GDM women were 94.4%, 93.9%, and 89.3%, respectively. The use of abdominal circumference (AC) at >90th percentile showed lower sensitivity but higher specificity, regardless of GDM status. Combination of both measurements increased sensitivity to approximately 90% or higher in every time point, especially among GDM women.ConclusionSignificant increase in fetal AAWT was observed in GDM women at 28–30 and 32–34 weeks. Fetal AAWT significantly increased among LGA infants and had higher sensitivity than AC in identifying LGA during third trimester. In GDM women at 28–30 weeks, AAWT ≥2.0 mm and AC >90th percentile had 97.2% sensitivity for LGA diagnosis.     

双球囊与缩宫素用于促宫颈成熟以及引产的效果比较

目的比较双球囊与缩宫素用于促宫颈成熟并引产的临床效果。方法选取于2017年7月—2018年7月在本院分娩的足月妊娠孕妇100例为研究对象,随机平均分为观察组和对照组各50例,观察组采用双球囊引产,对照组采用缩宫素进行引产,对比2组孕妇的总产程、宫颈成熟度、引产成功率和新生儿Apgar评分、并发症发生率等。结果观察组促宫颈成熟有效率(100%)、引产成功率(96%)均高于对照组(82%,74%),差异均有统计学意义(P<0.05),治疗后新生儿Apgar评分、并发症发生率差异均无统计学意义(P>0.05);宫颈Bishop评分观察组(9.12±1.42)高于对照组(7.92±1.56),观察组总产程(8.23±2.54)h,对照组(13.45±3.77)h,差异均有统计学意义(P<0.05)。结论双球囊用于妊娠引产效果显著,能明显促进宫颈成熟、缩短产程,保障分娩的顺利进行,安全可靠,值得在临床中推广。     

A comparison of double single suture-button fixation,suture-button fixation,and screw fixation for ankle syndesmosis injury: A retrospective cohort study

Different methods have been used throughout the years for syndesmotic injury but there is no consensus on the ideal treatment. Some methods are expensive and some have more complications. The aim of this study is to compare single suture endobutton with double suture endobutton and screw fixation for syndesmotic injury.Sixty nine patients with syndesmotic injury with fibular fractures whom were treated with a single interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet), a double interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet) and 1 syndesmotic screw (TST, Istanbul, Turkey) were included in this study. Functional and radiological results from patient records between 2015 and 2018 were retrospectively evaluated.Twenty patients were treated with the double interosseous suture endobutton, 23 were treated with the single interosseous suture endobutton, and 26 were treated with traditional AO screw fixation. Three patients from the screw fixation group (11.5%) required revision surgery (P < .05). All the radiologic and clinical outcomes were statistical similar in all 3 groups.Our findings showed that the interosseous suture endobutton system is at least as safe as the screw fixation technique for treatment of syndesmosis joint injuries and can be used as an alternative to the screw method. The interosseous suture endobutton system eliminates the need for a second surgery to remove the hardware, which minimizes the probability of re-diastasis. Since our results showed no statistical difference between single and double interosseous suture endobutton systems, the less costly single endobutton system may be the better alternative.     

子宫颈癌腹腔镜手术与开腹手术争议的解决之道——临床试验研究

        我国是子宫颈癌发病大国，新发病例为9.89万/年，死亡病例3.05万/年，新发病例占全球的19%［1］。根据中国子宫颈癌临床诊疗大数据库的资料，我国72.7%的子宫颈癌患者FIGO分期为ⅠA1～ⅡA2期可手术病例，接受手术为主的综合治疗的患者占72.9%［2］。此外，与西方国家不同，手术病例多是我国子宫颈癌诊疗中的一大特点。根据中国子宫颈癌临床诊疗大数据库的数据，中国子宫颈癌腹腔镜手术的比例从2009年的7.8%快速升高，至2016年腹腔镜手术占比高达79.1%，子宫颈癌腹腔镜手术在中国深受医生患者的喜爱。 浏览更多请关注本刊微信公众号及当期杂志。     

Evaluation of the anterolateral ligament of the knee by magnetic resonance imaging in patients with chronic anterior cruciate ligament rupture

ObjectiveThe purpose of this study was to evaluate the visibility of the anterolateral ligament (ALL) by magnetic resonance imaging (MRI) in patients with chronic anterior cruciate ligament (ACL) rupture.Materials and methodsThis retrospective case – control study compared 1.5 - T MRI scans for 50 patients with a chronic ACL rupture with those of a control group of 50 patients with an intact ACL. The ALL was evaluated in three portions: femoral, meniscal, and tibial. The status of each portion was classified as visualized or non-visualized. Two radiologists separately reviewed all the MRI scans to evaluate interobserver reliability.ResultsAt least one portion of the ALL was visualized in 100% of the control group and 72% of the chronic ACL rupture group. All three portions of the ALL were identified in 72% of the control group but only 10% of the chronic ACL rupture group. In both groups, the most commonly visualized portion was the meniscal portion and the least visualized was the tibial portion. In 18% of the chronic ACL rupture group, no portion of the ALL was visualized.ConclusionsThe visibility of the ALL of the knee was significantly lower in patients with a chronic ACL rupture than in those with an intact one.
