“…On a sagittal computed tomography view of the wrist, the curvature of the distal radial articular facet is greater than that of the proximal lunate articular facet, and the curvature of the proximal lunate articular facet is greater than that of the distal articular facet (Kijima et al, 2009) ( Figure 5(a)). Therefore, when a bone disruption occurs at the weak site ( Figure 5(b)) of the palmar or dorsal region of the distal articular surface as a result of an external force, the distal part of the fracture tends to become separated and the curvature of the proximal lunate articular facet tends to become flatter and to be more similar to that of the distal radial facet.…”

Seventeen fresh lunates with stage III Kienböck's disease were scanned with micro-computed tomography. Four regions of interest were selected to measure trabecular parameters, which were compared with those from normal lunates. Within the three regions in the distal surface, there was more compact trabecular bone in the middle region when compared with the palmar and dorsal regions. In the central part, the trabeculae of the Kienböck's lunates were much thicker than those in normal lunates. The diameters of the palmar nutrient foramina of the Kienböck's lunates were significantly smaller than those in normal lunates. In affected lunates, the bony disruptions were mostly located in the palmar or dorsal areas, which were shown from trabecular bone structure analysis to be structurally weaker. This leads to separation of the distal part of the fractured bone, disruption of the blood supply, poor bone remodelling and proneness to secondary fracture and eventual collapse.

“…38 Some authors did not report on an attachment on the scaphoid. 37,40 Radial collateral ligament (RCL): The RCL is the most radial carpal structure and is a controversial ligament because many surgeons deny its existence. The greatest controversy is whether it is a separate ligament 12,15,36,41,42 or the most radial bundle of the RSC ligament 32,37,40 (Fig.…”

“…Most recent studies mention either 2 distinguishable STT ligament bundles or 2 separate ligaments, the scaphotrapezium (ScTm) and the scaphotrapezoid (ScTd) ligaments. 1,32,35,40 Each courses distally, forming the volar STT capsule, and inserts in the proximal volar edges of the trapezium and trapezoid, respectively. The precise function of the STT ligament is not clear, but it would seem to be an important stabilizer of the scaphoid and STT joint that minimizes excessive scaphoid flexion.…”

KEYWORDSUltrasound; Extrinsic carpal ligaments; Rheumatoid arthritis; Wrist; Wrist instability.Abstract Thanks to its intrinsic high spatial resolution, ultrasound is an ideal imaging modality for examining very thin, superficial structures, and this makes it very helpful in the evaluation of extrinsic carpal ligaments. These structures, which arise from the radius and ulna and insert on the carpal bones, are extremely important for wrist stability. Previous studies have assessed the use of ultrasound to study the extrinsic carpal ligaments in cadavers, healthy asymptomatic subjects, and patients with rheumatoid arthritis. In the present report, we review the normal anatomy, biomechanics, and ultrasound appearance of these ligaments.Sommario L'ecografia è una metodica di imaging che, grazie alla sua elevata risoluzione spaziale, appare ideale nella valutazione di strutture superficiali anche molto sottili. Questa ca-ratteristica la rende una metodica estremamente valida nella valutazione dei legamenti estrinseci del carpo. Tali strutture originano dal radio e dall'ulna e si inseriscono sulle ossa della filiera carpale dando così un contributo fondamentale alla stabilità del carpo. Solo due studi in letteratura hanno descritto l'utilizzo dell'ecografia nella valutazione dei legamenti estrinseci del carpo su cadavere e in pazienti sani asintomatici. Un terzo studio ha invece decritto l'aspetto di tali legamenti in pazienti affetti da artrite reumatoide. Nel presente studio è riportata una revisione dell'anatomia normale, della biomeccanica, e dell'aspetto ecografico dei legamenti estrinseci del carpo. ª
