Ultrasound is quickly becoming the TMJ’s new best friend. While MRI still wears the crown for deep‑dive soft‑tissue detail, high‑resolution sonography now gives us a surprisingly clear, real‑time look at what’s happening right under the zygomatic arch. This presentation explores how ultrasound can help clinicians spot common TMJ troublemakers—like effusions, synovitis, capsular thickening, and even those subtle cortical bumps that patients swear they can “feel clicking.” We’ll walk through practical scanning tips, smart probe choices, and dynamic jaw manoeuvres that make the disc dance on screen. Case examples show where ultrasound shines and where it still needs a little backup from MRI. Overall, TMJ sonography offers an accessible, patient‑friendly way to add valuable functional insight to the diagnostic mix. It may not replace MRI, but it’s a fast, low‑cost tool that’s earning its spot in everyday TMD assessment.

Fracture detection with ultrasound is an established but often under-recognised skill, with significant clinical value in musculoskeletal imaging. This presentation acknowledges that while some sonographers are already confident in this area, many remain unfamiliar with the key sonographic signs or assume fractures cannot be reliably assessed with ultrasound. Through a review of basic principles, common pitfalls, and practical scanning fundamentals, this session aims to build confidence and awareness. A series of case studies will demonstrate real-world applications and highlights the benefits of clinical history and exploring further than basic protocol. As fracture imaging is not routinely covered in standard ultrasound training, proficiency is often dependent on individual case exposure and mentorship, contributing to variable knowledge and utilisation in clinical practice.

Introduction: This poster/oral presentation will unpack the sonographic anatomy and technique to image the triangular fibrocartilage complex (TFCC) and distal radioulnar joint (DRUJ).
Overview: The TFCC is an intricate fibrocartilage-ligamentous complex which has three main functions: 1. Stabilises the DRUJ, 2. Stabilises the ulno-carpal space and 3. Acts as a cushion and shock absorber and transmits load through the wrist during different wrist positions. The DRUJ is inherently unstable, relying heavily on intrinsic and extrinsic soft tissue structures. The TFCC is a well-defined anatomical entity which functions primarily to stabilize the distal radio-ulnar joint (DRUJ) and act as a shock absorber across the ulno-carpal space. The main components of the TFCC include the: 1. Disc proper, 2. Meniscus homologue, 3. Extensor carpi ulnaris (ECU) tendon sub-sheath, 4. Two palmar sided ulno-carpal ligaments: the ulno-lunate ligament (ULL) and the ulno-triquetral ligament (UTL) and 5. Two distal radio-ulnar ligaments: the dorsal distal radioulnar ligament (DDRUL) and the palmar distal radioulnar ligament (PDRUL).
Content: This poster will unpack the normal appearances and location of each component of the TFCC and DRUJ structures. Also a guide to the technique to enhance visualisation of the TFCC and DRUJ through patient positioning, probe placement and dynamic manoeuvrers will be presented. The poster/oral presentation will draw from the recently published journal article “Sonographic anatomy and imaging of the intertwined triangular fibrocartilage complex and the distal radio-ulnar joint”.
