“…However, in particular in regard to the measurement of small tendon changes, point-wise manual measurement is only usable on a conditional basis due to its limited reproducibility (variation coefficient approx. 5 -7 %) [13,14,55]. Automated contour recognition methods improve reproducibility by up to 50 % in both B-mode ultrasound and MRI [14,50,51].…”

In the past decades the incidence of acute and chronic disorders of the Achilles tendon associated with sport-induced overuse has steadily increased. Besides acute complete or partial ruptures, achillodynia (Achilles tendon pain syndrome), which is often associated with tendon degeneration, represents the most challenging entity regarding clinical diagnostics and therapy. Therefore, the use of imaging techniques to differentiate tendon disorders and even characterize structure alterations is of growing interest. This review article discusses the potential of different imaging techniques with respect to the diagnosis of acute and chronic tendon disorders. In this context, the most commonly used imaging techniques are magnetic resonance imaging (MRI), B-mode ultrasound, and color-coded Doppler ultrasound (US). These modalities allow the detection of acute tendon ruptures and advanced chronic tendon disorders. However, the main disadvantages are still the low capabilities in the detection of early-stage degeneration and difficulties in the assessment of treatment responses during follow-up examinations. Furthermore, differentiation between chronic partial ruptures and degeneration remains challenging. The automatic contour detection and texture analysis may allow a more objective and quantitative interpretation, which might be helpful in the monitoring of tendon diseases during follow-up examinations. Other techniques to quantify tendon-specific MR properties, e.?g. based on ultrashort echo time (UTE) sequences, also seem to have great potential with respect to the precise detection of degenerative tendon disorders and their differentiation at a very early stage.

Additionally, in a number of conducted studies, the researchers aimed at finding the thickness of achilles and patella tendons through the ultrasonographic method (Fredberg et al, 2008;Kallinen & Suominen, 1994;Koivunen-Niemelä & Parkkola, 1995). Chao et al (1997) researched into the termination positions of the achilles tendons anatomically in fresh cadavers.…”

A Study on the Structure and Morphologic Development of Calcaneal Tendon and Triceps Surae Muscle in Human Fetuses during the Fetal Period and the Evaluation of Clinical Importance of Calcaneal Tendon

SUMMARY: It was aimed that the morphometric development of calcaneal tendon and the structures building it up in human fetuses during the fetal period be anatomically studied and that its clinical importance be evaluated. The study comprised a total of 102 fetus legs (51 human fetuses: 26 male and 25 female) whose ages varied between 15-40 gestational week, without external pathology or anomaly. The fetuses were divided in groups according to gestational weeks, trimesters and months. In the wake of the general external measurements of fetuses, leg dissection was performed. Afterwards, the morphometric parameters of gastrocnemius muscle, soleus muscle and calcaneal tendon were measured. The averages and the standard deviations of the measured parameters were determined according to gestational weeks, trimesters and months. There was a significant correlation between the measured parameters and the gestational age (p<0.001). There was no difference between sexes in terms of parameters (p>0.005). All the obtained results were discussed by making a comparison between them and the previous studies made. We are of the opinion that the data obtained in our study will be of use to the involved clinicians in the evaluation of the development of calcaneal tendon and the structures constituting it during the fetal period and in clinical studies and applications as well.

Best‐practice guidelines have incorporated ultrasound in diagnostic and procedural medicine. Due to this demand, the Arizona College of Osteopathic Medicine initiated a comprehensive integration of ultrasound into its first‐year anatomy course attended by more than 280 students. Ultrasound workshops were developed to enhance student conceptualization of musculoskeletal (MSK) anatomy through visualizing clinically important anatomical relationships, a simulated lumbar puncture during the back unit, carpal tunnel and shoulder evaluations during the upper limb unit, and plantar fascia, calcaneal tendon, and tarsal tunnel evaluations during the lower limb unit. A 5‐point Likert scale survey evaluated if ultrasound improved students' self‐perceived anatomical and clinical comprehension of relevant anatomy, improved students' ability to orient to ultrasound imagery, and prompted further independent investigation of the anatomical area. Ultrasound examination questions were added to the anatomy examinations. Two‐tailed one‐sample t‐tests for the back, upper limb, and lower limb units were found to be significant across all Likert survey categories (P < 0.001). Positive student responses to the Likert survey in conjunction with examination question average of 84.3% (±10.3) demonstrated that the ultrasound workshops are beneficial to student education. Ultrasound enhances medical students' clinical and anatomical comprehension and ability to orient to ultrasound imagery for MSK anatomy. This study supports early ultrasound education as a mechanism to encourage students' independent learning as evidenced by many undertaking voluntary investigation of clinical concerns associated with MSK anatomy. This study establishes the successful integration of MSK ultrasound into a large medical school program and its benefit to student clinical education.
