Ultrasound Features of Adhesive Capsulitis.

Introduction: Adhesive capsulitis (AC), which is characterised by shoulder pain and a limited range of motion (ROM), is usually diagnosed on the basis of clinical suspicion, with imaging only being used to exclude other causes of similar symptoms. The aim of this study was to identify and describe the typical ultrasound (US) features of AC in a group of patients with shoulder pain and stiffness.

Methods: This was a cross-sectional study of 1486 patients with AC in which two experienced US specialists examined the axillary pouch (AP), the coracohumeral ligament (CHL), the superior glenohumeral ligament (SGHL), and the long head of the biceps tendon (LHBT), and dynamically visualised the infraspinatus tendon during passive external rotation (PER) during a US evaluation of shoulder ROM.

Sonographic visibility of the main posterior ankle ligaments and para-ligamentous structures in 15 healthy subjects.

The present article describes the ultrasound (US) appearance of ligaments and paraligamentous structures which are not included in standard US imaging of the ankle: the posterior inferior tibiofibular ligament (PITFL), the transverse tibiofibular ligament (TTFL), the posterior talofibular ligament (PTFL), the posterior intermalleolar ligament (PIL), the synovial recess (SR) of the posterior joint and the os trigonum (OT). Two skilled operators examined 15 ankles in 15 healthy volunteers. Correlation between thickness of the main ligaments and body mass index (BMI) was also analyzed.

Sonographic visibility of the sinus tarsi with a 12 MHz transducer.

Objectives: To assess the value of ultrasonography in studies of the ligaments within the sinus tarsi (ST) in healthy subjects.

Materials And Methods: We examined 20 healthy volunteers using a 12-MHz transducer with THI and compound imaging. With the foot in inversion, the following structures were examined with coronal and transverse scans: (1) the root of the inferior extensor retinaculum (RIER); (2) the interosseous talocalcaneal ligament (ITCL); (3) the cervical ligament (CL); (4) the bifurcate ligament (BL); (5) the synovial recesses, which were examined for possible distention (distended synovial recesses, DSR).
