摘要

踝关节前抽屉试验被广泛用于诊断踝关节扭伤引起的距腓骨前韧带损伤；然而，低灵敏度已被报道。三角韧带的制动作用可能是造成这种低敏感性的原因。本研究旨在检查后足持续和强制内旋导致三角韧带松弛对常规前抽屉测试的影响。方法采用可拉伸应变传感器对7例尸体踝关节标本在跖屈30°，内旋或不内旋10°时进行定量分析，并采用惯性测量单元精确监测三轴关节角度。前抽屉距离（mm）由可拉伸应变传感器检测到的电容值（皮法拉）的变化计算，并与前距腓骨韧带分离时的测量结果进行比较。双向重复测量方差分析和事后两两分析显示，在距腓骨前韧带分离样本中，内旋前抽屉试验的平均值显著高于常规前抽屉试验（4.7±1.6 mm vs 2.2±1.5 mm） (P <；0.001)。电容数据显示，类内相关系数（1,1）为0.903。目前的研究结果表明，我们改良的前抽屉试验，持续和强制内旋，防止三角韧带的制动作用，并有望提高评估距腓骨前韧带损伤的敏感性。

Effect of internal rotation of the hindfoot on diagnosis of anterior talofibular ligament injury: An in vitro simulation study

Background

The anterior drawer test of the ankle is widely used to diagnose anterior talofibular ligament injuries caused by ankle sprains; however, low sensitivity has been reported. The braking effect of the deltoid ligament is likely responsible for this low sensitivity. This study aimed to examine the effect of consistent and mandated internal rotation of the hindfoot, which leads to relaxation of the deltoid ligament, on the conventional anterior drawer test.

Methods

Seven cadaveric ankle specimens were subjected to quantitative analysis with a stretchable strain sensor at 30° plantarflexion, with or without 10° internal rotations, under accurate three-axial joint angle monitoring using inertial measurement units. The anterior drawer distance (mm) was calculated from the measured change in the capacitance value (picofarad) detected using the stretchable strain sensor and compared with that measured with the anterior talofibular ligament detached.

Findings

A two-way repeated measures analysis of variance and post-hoc pairwise analysis revealed that the anterior drawer test with internal rotation revealed a significantly greater mean value than the conventional anterior drawer test (4.7 ± 1.6 mm vs. 2.2 ± 1.5 mm) in anterior talofibular ligament-detached samples (P < 0.001). The capacitance data revealed an intraclass correlation coefficient (1,1) of 0.903.

Interpretation

Present findings suggest that our modified anterior drawer test with consistent and mandatory internal rotation, prevents the braking effect of the deltoid ligament and is expected to improve the sensitivity in assessing anterior talofibular ligament injuries.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
