Aim of study: Most sprained lateral ankle ligaments heal uneventfully, but in some cases the ligament’s elastic function is not restored, leading to chronic ankle instability. Ultrasound shear wave elastography can be used to quantify the elasticity of musculoskeletal soft tissues; it may serve as a test of ankle ligament function during healing to potentially help differentiate normal from ineffective healing. The purpose of this study was to determine baseline shear wave velocity values for the lateral ankle ligaments in healthy male subjects, and to assess inter-observer reliability. Material and methods: Forty-six ankles in 23 healthy male subjects aged 20–40 years underwent shear wave elastography of the lateral ankle ligaments performed by two musculoskeletal radiologists. Each ligament was evaluated three times with the ankle relaxed by both examiners, and under stress by a single examiner. Mean shear wave velocity values were compared for each ligament by each examiner. Inte...
The value of diagnostic ultrasound in the diagnosis of musculoskeletal disorders
International Journal of Physical Education, Sports and Health
Diagnostic ultrasound is used to detect and evaluate the degree of inflammation of the synovial membrane in cases of suspected inflammatory arthritis. In cases of non-inflammatory aetiology, the ultrasound can identify problems related to soft tissue. The purpose of this study was to investigate the success rate in the diagnosis of musculoskeletal disorders using ultrasound imaging and the confirmation rate of the ultrasound findings with other imaging methods, such as magnetic resonance imaging (MRI) and radiography (X-ray). The sample of the present study consisted of 120 patients who suffered from musculoskeletal disorders, and they visited the Orthopedic Outpatient Clinics of the General Panarkadikon Hospital in, Greece. All patients were examined by the orthopaedic doctor, who used an ultrasound device. After the ultrasound procedure, the doctor made a possible diagnosis, and then the patient underwent at least one more diagnostic process, and then both the outcomes were compared. An anonymous questionnaire was used to record the outcomes of the ultrasound per anatomic part and compare the results to the other diagnostic procedures. There were no statistically significant differences for gender and ultrasound confidence level (p=0.315), gender and MRI/X-ray confirmation level (p=0.966), age and ultrasound confidence level (p=0.374), age and MRI/X-ray confirmation level (p=0.081) and injuries type with MRI/X-ray confirmation level (p=0.070). The anatomical area was related to the ultrasound confidence level (p<0.001) and to the MRI/X-ray confirmation level (p= 0.017). The type of injuries was related to the ultrasound confidence level (p=0.026). The diagnosis was related to the ultrasound confidence level (p<0.001) and to the MRI/X-ray confirmation level (p < 0.001). In conclusion, it seems that ultrasound is a fast imaging tool, which can provide very helpful information about the damaged tissue and permit an experienced doctor to make a safe diagnosis.
Ultrasound in sports medicine—A critical evaluation
European Journal of Radiology, 2007
This article will discuss the aspects of sports medicine where ultrasound imaging has advantages when compared to MRI looking at the strengths and weaknesses of ultrasound in the context of diagnosis and management. It will also assess the use of ultrasound in therapy including guided injections and current thoughts on novel forms of treatment. We will particularly emphasise the role of ultrasound imaging in the management of injuries of tendon, ligament and muscle.

Ultrasound Imaging in Sport-Related Muscle Injuries: Pitfalls and Opportunities
Medicina
Muscle injuries occur frequently in athletes, accounting for more than one-third of sport-related trauma. Athletes most affected by these injuries are those practicing football and track and field, with hamstrings and gastrocnemius-soleus as the mainly involved sites. Muscle injuries lead to loss of competitions, long recovery times and risk of re-injury with a consequent increase of the management costs. It is therefore advisable to make an accurate and timely diagnosis to establish appropriate interventions for proper healing in the shortest time. In this context, ultrasound imaging is widely used for diagnosis of musculoskeletal disorders because of several advantages including absence of radiation, portability, good spatial resolution, and the ability to perform dynamic tests. The aim of this review is to address the role of US in the evaluation of athletes with muscle injuries. US may play a pivotal role for the management of sport-related muscle injuries because it is fast and...

Ultrasonography (US) may aid the assessment of the anterior talofibular ligament (ATFL) injury after lateral ankle sprains by allowing the clinician to visualize and measure talocrural laxity. Comparison of US against another objective method of ankle laxity assessment, such as ankle arthrometry (AA), is needed. The purpose was to evaluate the relationship between the ATFL length measurements measured from stress US images to the inversion and anterior drawer displacement measured with AA in healthy subjects. This descriptive laboratory study included 26 ankles from healthy subjects. The apparent length of the ATFL was measured using US during anterior drawer (USAD) and inversion (USINV) stress and the translation of the talocrural joint was measured using AA during anterior drawer (AAAD) and inversion (AAINV) stress. Percent change in length for USAD and USINV were quantified. Intraclass correlation coefficients and pearson product moment correlations Bland-Altman limits of agreeme...

Objective: Ankle sprains constitute approximately 85% of all ankle injuries and up to 70% of people experience residual symptoms. Whilst the injury to ligaments is well understood the potential role of other foot and ankle structures has not been explored. The objective was to characterise and compare selected ankle structures in participants with and without a history of lateral ankle sprain. Methods: 71 participants were divided into 31 healthy, 20 coper, and 20 chronic ankle instability groups. Ultrasound images of the anterior talofibular and calcaneofibular ligaments, fibularis tendons and muscles, tibialis posterior and Achilles tendon were obtained. Thickness, length, and cross sectional areas were measured and compared between groups. Results: When under tension the anterior talofibular ligament was longer in copers and chronic ankle instability groups compared to healthy participants (p <0.001 and p = 0.001 respectively). The chronic ankle instability group had the thickest ATFL and CFL among the three groups (p ˂ 0.001). No significant differences (p >0.05) in tendons and muscles were observed between the three groups. Conclusions: The ultrasound protocol proved reliable and was used to evaluate the length, thickness, and CSA of selected ankle structures. The length of the ATFL and the thickness of the ATFL and CFL were longer and thicker in injured groups compared to healthy.
Role of Ultrasound in Evaluation of Ankle Joint
PARIPEX - INDIAN JOURNAL OF RESEARCH, 2016
High resolution ultrasound is an excellent cost-effective modality in imaging normal anatomy and abnormal pathologies in and around ankle joint. With advent of newer transducers and technological developments we will be able to image much superficial lesions. Beam steering or compound imaging can help to overcome anisotropy of tendons. Ultrasound can detect and evaluate acute injuries, chronic pain, chronic instability, impingement and failure of conservative treatment of ankle swelling. This article describes anatomy, pathology, scanning technique and protocol for ankle ultrasound.
Comparative assessment of the acute ankle injury by ultrasound and magnetic resonance
Collegium antropologicum, 2012
We compared ultrasound (US) with magnetic resonance (MR) findings of muscle tendon and ligaments (mt&l) of 17 men and 13 women, 16-66 years old, who suffered from acute ankle injury without bone fracture visible on conventional radiographs. Joint effusion (JE), and injury of the Tibials anterior muscle tendon (TAmt), Calcaneofibular ligament (CFl), Long flexor of the great toe muscle tendon (LFGTmt), Short peroneus muscle tendon (SPmt), Long peroneus muscle tendon (LPmt), and Anterior talofibular ligament (ATFl) were assessed by the US, at seven days, and MR, at seventeenth day. Grading of ligament and muscle tendon injury as stretching (Grade 1), partially ruptured (Grade 2), and complete rupture (Grade 3); no lesion was considered to be Grade 0. Joint effusion and ATFl were the most common lesions whereas the TAmt lesion was the least frequent: JE approximately ATFl > SPmt approximately LPmt > LFGTmt approximately CFl approximately TAmt. Both US and MR were equally sensitive...
