Imaging strategy for wrist injury usually begins with standard radiographs. When a ligamentous disorder is suspected clinically, the next step is arthrographic computed tomography or arthrographic magnetic resonance imaging. When the diagnosis remains unclear, magnetic resonance imaging (MRI) is the preferred examination. Ultrasonography is usually used to assess structures like tendons and bone surface, but thanks to the performances of high-frequency transducers, it can also enable visualization of the main ligaments of the wrist. Ultrasonography could thus replace MRI because of its lower cost, as recently reported in the literature. However, a good knowledge of normal and pathological wrist anatomy is required to avoid false negatives. Wrist ligaments comprise interosseous and capsular ligaments as well as the triangular fibrocartilaginous complex. All these ligaments may be involved in carpal instability. Clinical examination has a major role to play in helping radiologists orient their procedures. A few studies have reported that ultrasonography of the triangular fibrocartilaginous complex is reliable compared with arthrography or MRI, but most of these studies were limited to the radioulnar ligaments. In this article we propose a more extensive protocol.

“…29 The extrinsic ligaments connect the carpus with the forearm bones or the radioulnar ligaments and are further subdivided into dorsal, palmar, and collateral ligaments. [30][31][32] The extrinsic palmar ligaments ( Figure 13) form 2 arcuate structures, respectively attaching to the capitate on the distal carpal row (greater arc) and outlining the lunate on the proximal row (lesser arc). 6 The triangular area between these arcs is called the space of Poirier and is vulnerable to injury and dislocation, as it is not covered by any ligaments.…”

Sonography allows for rapid, cost-effective, noninvasive, and dynamic evaluation of soft tissue structures, thus representing a valuable tool for ruling out musculoskeletal disorders of the wrist. Because of the complexity of the wrist joint, sonographic training and familiarity with normal and variant anatomy are needed to avoid misdiagnosis and improper treatment. The aim of this article is to enlighten readers about the structures representing normal findings or common variants during sonographic evaluations of the wrist. The main text reviews the pertinent gross anatomy and procedures that are recommended to assess the soft tissue structures of the wrist, with particular emphasis given to tendons, nerves, and ligaments. Detailed explanations of the scanning techniques and sonographic appearance of the wrist structures are provided in the figure legends.

The anatomy of the extrinsic capsular wrist ligaments is complex. These ligaments are probably as important as the intrinsic interosseous ligaments for the maintenance of carpal stability. The extrinsic capsular wrist ligaments are frequently divided into dorsal, palmar, and collateral depending on their anatomical location. They have known origin and attachment sites with recognized anatomical variants. However, there is controversy in the literature related to their anatomy and nomenclature. In the past two decades, imaging has gained an important role in the evaluation of the extrinsic capsular wrist ligaments. Both 1.5-T magnetic resonance imaging (MRI) and magnetic resonance arthrography can provide good evaluation of the extrinsic capsular wrist ligaments; 3-T MRI with improved resolution provides better visualization of the same anatomical structures. Ultrasonography using high-resolution linear transducers allows good visualization of the extrinsic capsular wrist ligaments with results that are comparable with MRI. This article describes the normal anatomy of the dorsal, palmar, and collateral extrinsic capsular wrist ligaments on 3-T MRI and high-resolution ultrasonography.
