“…Moritomo et al 8) showed that the direction of the capitate motion relative to the scaphoid and the lunate inclined in a similar way in the flexionextension motion. Smith et al 9) have concluded that the scaphoid serves an important role in maintaining normal alignment of the carpal bones and in producing normal wrist motion, and Sennwald et al 3) have suggested that the lunate is intercalated both longitudinally and transversely with the adjacent carpal bones.…”

“…In the wrist joint, accessory movement of the carpal bones occurs against the radius during extension (dorsiflexion) -flexion (palmar-flexion) motion. A number of previous studies have described changes in the patterns of carpal bone movement during wrist motion [2][3][4][5][6][7][8][9][10][11][12][13][14] , some of which have specifically examined the motion of the lunate during wrist extension-flexion [2][3][4] . Moojen et al 2) reviewed the contribution of the scaphoid and the lunate to the inplane motion during flexion-extension of the wrist.…”

Abstract. This study investigated the accessory movement of the lunate in the volar-dorsal direction during active flexion-extension motion of the wrist. The right wrist of a healthy 50-year-old (right-handed) male was studied using an ultrasound diagnostic instrument to measure the wrist's continuous motion from (neutral to) flexion to extension (back to neutral). An ultrasound system was applied on the dorsal aspect of the subject's wrist over the radiocarpal joint. The distance between the dorsal plane of the radius and that of the lunate was measured in each image. The distance data were depicted on a graph using the method of least squares. The lunate moved 0.5 mm dorsally during flexion, and it moved 1.5 mm in the palmar direction during extension. The variance value of the 5th degree polynomial expression of the curve was 0.147. It is hoped that our polynomial expression in this study will serve as a frame of reference in the evaluation of a given mode of physical therapy prescribed for subjects with joint dysfunction.

“…c The mean rotation angles of internal/ external rotation of the scapula. No significant differences were observed analysis system and have used this to perform various joint analyses [11,[22][23][24][25]. This method enables the computation of parameters such as angles of rotation of each bone and transformation distances, by performing MRI in different arm positions and using the voxel-based registration method on the resulting data to superimpose images of the same bone in different arm positions.…”

Purpose The purpose of this study was to assess accurately the three-dimensional movements of the scapula and humerus relative to the thorax during internal/external rotation motion with abduction of the shoulder joint. Methods Ten right shoulders of ten healthy volunteers were examined using a wide-gantry open magnetic resonance imaging (MRI) system. MRI was performed every 30°from 90°external rotation to 90°internal rotation of the shoulder joint. Results The contribution ratio of the scapulothoracic joint was 12.5% about the long axis of the humerus during internal/external rotation motion. With arm position changes from 90°external rotation to 60°internal rotation, most movement was performed by the glenohumeral joint. Conversely, at internal rotation of ≥60°, the scapula began to markedly tilt in the anterior direction. At 90°internal rotation, the scapula was significantly tilted anteriorly (p< 0.05) when compared with the other positions. Conclusions We clarified the existence of a specific scapulohumeral motion pattern, whereby the glenohumeral joint moves with internal rotation and the scapulothoracic joint moves with anterior tilt together with internal rotation motion of the shoulder joint.

“…On peut considérer la seconde rangée du carpe comme un bloc, car les mouvements entre les os qui la composent sont d'une amplitude négligeable, tandis que la première rangée modifie sa configuration en permanence pour s'adapter aux morphologies du bloc ulnocarpien et de la seconde rangée [4][5][6]. En effet, la première rangée est située entre le squelette de l'avant-bras et la seconde rangée du carpe.…”

“…Inversement, lors de l'inclinaison ulnaire, le radius s'éloigne de la seconde rangée, ce qui laisse de la place pour que le scaphoïde se redresse (se verticalise, s'étende) (Figs. 3,4). Cette extension est due, notamment, à l'effet du ligament SL qui tire vers le haut le pôle proximal du scaphoïde.…”

L'anatomie et la physiologie du carpe sont extrêmement complexes, ce qui explique la difficulté du diagnostic d'une entorse grave du poignet qui, si elle est mal traitée, va évoluer vers l'instabilité chronique, source de douleurs et d'arthrose. Nous proposons un algorithme clinique pour évaluer les entorses scapholunaires, mais également lunotriquetrales, et une analyse des radiographies basée sur les notions anatomiques pour ne pas méconnaître les lésions ligamentaires associées aux fractures du poignet.Mots clés Poignet · Entorses · Ligaments · Scapholunaire · Lunotriquetral · Examen clinique · Examen radiographique Abstract The anatomy and physiology of the wrist are very complex, which is why it is difficult to diagnose a severe wrist sprain, which, if inadequately treated, will result in wrist pain and degenerative arthritis. We propose a clinical algorithm for assessing both scapholunate and lunotriquetral sprains. We also propose a radiological analysis of wrist fractures based on anatomical concepts, so as to avoid missing ligamentous lesions associated with wrist fractures.
