二维斑点追踪成像定量评价妊娠期糖尿病胎儿右心室功能变化的研究

Assessment study of right ventricular function by 2-dimensional speckle tracking imaging in fetuses with gestational diabetes mellitus

目的：对比应用Endobutton联合Intrafix与可吸收挤压螺钉在关节镜下进行自体腘绳肌腱重建前交叉韧带的疗效。方法选取自2012年7月至2013年8月于青岛大学附属医院行自体腘绳肌腱重建前交叉韧带的患者60例，分为两组。第一组30例患者运用Endobutton联合Intrafix固定，第二组30例患者用可吸收挤压螺钉固定。观察并记录术前及术后膝关节前抽屉试验、Lachman试验、轴移试验结果及Lysholm膝关节评分和IKDC评分。结果两组患者均经过6～25个月的随访，第一组患者随访中有7例膝关节活动时仍有轻度疼痛，5例患者Lachman征Ⅰ度阳性。Lysholm评分和IKDC评分由重建前的（56.2±5.7）分和（50.0±4.3）分增长到重建后的（89.2±2.7）分和（90.1±3.1）分。经t检验，差异有统计学意义（P＜0.05）。第二组患者随访中8例膝关节活动时仍有轻度疼痛，7例Lachman征Ⅰ度阳性。Lysholm评分和IKDC评分由重建前（57.6±5.5）分和（51.4±4.5）分增长到重建后（88.8±2.5）分和（89.4±3.3）分，经t检验，差异有统计学意义（P＜0.05）。两组患者重建后Lysholm评分和IKDC评分差异无统计学意义（P＞0.05）。结论经过分析，在交叉韧带重建手术中，Endobutton联合Intrafix与可吸收挤压螺钉均是良好的固定方法，各有优势。

Objective To compare the clinical results of Endobutton joint Intrafix and absorbable interference screw fixation after ACL reconstruction with autologous hamstring tendon. Methods 60 patients who had been treated with arthroscopic ACL reconstruction using autologous hamstring tendon, were selected from Affiliated Hospital of Qingdao University （2012-07 to 2103-08）. According to different fixation, they were divided into group one （30 patients, with Edobutton joint Intrafix） and group two （30 patients, with absorbable interference screw）. Preoperative and postoperative knee anterior drawer test, Lachman test, pivot shift test were observed. And knee function was evaluated by Lysholm and IKDC systems. Results The two groups of patients were followed up for 6-25 months. In the first group：7 patients knee still had mild pain, LachmanⅠdegree positive was in 5 cases. Lysholm and IKDC scores by 56.2±5.7 and 50.0±4.3 grew to 89.2±2.7 and 90.1±3.1. There were statistically significant differences between preoperation and postoperation （P〈0.05）. In the second group：8 patients knee still had mild pain, LachmanⅠdegree positive was in 7 cases. Lysholm and IKDC scores by 57.6±5.5 and 51.4±4.5 grew to reconstruction 88.8±2.5 and 89.4±3.3. There were statistically significant differences between preoperation and postoperation （P〈0.05）. After reconstruction, the Lysholm and IKDC scores of the two groups of patients was not statistically significant （P〉0.05）. Conclusions After analysis, both ways are reliable fixation ways in anterior cruciate ligament.
