Abstract

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.
