抽屉试验

目的评估前抽屉试验、Lachman试验、轴移试验和MRI在陈旧性前十字韧带损伤诊断中的意义。

Objective To estimate the value of anterior drawer test , Lachman test , pivot shift test and MRI in diagnosis of chronic anterior cruciate ligament injury .

两组术前和术后前抽屉试验、Lachman试验轴移试验和稳定性单项评分比较，差异均无显著性（P均>0.05）。

The difference of the comparison between the two groups on anterior drawer test , Lachman test pivot shift test and stable simple score before and after operation was all insignificant ( P > 0.05 ) .

麻醉状态下抽屉试验及Lachman试验呈阴性。

The palpation by hook and Lachman test showed negative results .

临床膝关节稳定性测试105例（74.80%）前抽屉试验阴性；114例（81.40%）LachmanTest阴性；

The clinical examination of knee stability with anterior drawer testing was negative on 105 cases ( 74 . 80 % ) and with Lachman-Test on 114 cases ( 81 . 40 % ) .

随访时抽屉试验和Lachman试验阳性者3例，可疑阳性者6例，余患者均为阴性。

Follow-up drawer and Lachman tests positive test three cases , six cases of suspicious positive , more patients were negative .

方法107例手术证实为陈旧性前十字韧带损伤患者，术前均行前抽屉试验、Lachman试验、轴移试验和MR检查。

Methods One hundred and seven patients with the diagnosis of chronic injuries of the anterior cruciate ligament arthroscopically underwent the anterior drawer test , Lachman test , the pivot shift test and MR examination before operation .

结果前抽屉试验的阳性率为78.5%，Lachman试验为97.2%，轴移试验为91.6%，而MRI敏感性为93.5%。

Results 78.5 % of the patients had positive anterior drawer test , 97.2 % had positive Lachman test and 91.6 % had positive pivot shift test . The sensitivity of MRI was 93.5 % .

体检前抽屉试验（ADT）、Lachman试验和轴移试验（PST）阳性率，前内束断裂者分别为714%、143%和0；

Regarding the results of anterior drawer test , Lachman test and pivot shift test , it is positive 71.4 % , 14.3 % and 0 in AMB tears respectively ;

12例ACL部分损伤，前抽屉试验、Lachman试验和轴移试验的准确性分别为：16.7%、50.0%和33.3%。

In the partial anterior cruciate ligament tears cases , 16.7 % patients had positive anterior drawer test , 50.0 % had positive Lachman test and 33.3 % had positive pivot shift test .

结果随访1～3年，在单纯动力重建和单纯缝合实质部的损伤8例，后抽屉试验（PDT）（++）；

Results All the cases were followed up for 1 ~ 3 years . In the cases with the methods of dynamic reconstruction and simple suture of injuried substantial part of PCL ( 8 cases ), Posterior drawer test PDT still ( + + ) .

96例患者可有不同程度的膝关节不稳症状；术前查体，前抽屉试验阳性114例，Lachman试验阳性76例，轴移试验阳性49例。

96 of them had instability symptom of knee . Anterior drawer test was positive in 114 cases , Lachman test was positive in 76 cases , and Pivot shift test was positive in 49 cases .

14例异体髌腱移植重建前交叉韧带、髌骨供区植骨患者：前抽屉试验I度1例，Lachman试验（+）1例，轴移试验（+）1例；

Fourteen ACL reconstructions were performed at allograft patellar tendon : One patient was in the ADT I degree , 1 in the Lachman ( + ), 1 in the pivot shift test ( + ) .

19例行前抽屉试验检查，阳性12例。

19 patients received ADT , and 12 were positive .

结论前抽屉试验侧位片及内翻应力正位片对于慢性外踝不稳诊断具有重要意义。

Conclusion Both basic roentgenographic measurements have significant meanings to the diagnosis of chronic ankle instability .

结果：所有病人患膝关节稳定性明显增强，术后抽屉试验全部阴性。

Results : The stability of all patients knees are remarkably improved , and all drawer tests are negative after surgery .

术后6个月，1例患者有Ⅰ度后抽屉试验阳性，其余均为阴性。

Six months postoperatively , except for one case with ⅰ degree of positive posterior drawer test , no knee instability was detected ;

目的探讨前抽屉试验应力位片在慢性外踝关节不稳定诊断中的意义，提出影像学的定量诊断方法。

Objective To discuss the significance of anterior drawer stress radiograph in diagnosing of chronic instability of lateral ankle and bring forward the radiology diagnosis criteria .

结果治疗组较对照组总有效率和显效率、前抽屉试验评分均高，两者间有显著性差异。

Results The total effective rate and marked response rate in group A were higher than those in group B , with significant difference between the two groups ;

方法对有膝关节外伤史、膝关节检查有可疑交叉韧带损伤者，分别摄双侧膝关节屈膝90°前、后抽屉试验位X线侧位片。

Methods Lateral roentgenograms of bilateral knees , under the condition of anterior and posterior drawer tests , were taken if one patient had a history of knee joints trauma and was suspicious of suffering from cruciate ligaments injury after careful examination of both knees .
