The Trapezius muscle (also known as trapezoids or traps for short) resembles a diamond shaped quadrilateral (trapezoid) and is a large surface muscle that is located in the upper back of the human torso. Trapezoid Bone; Triquetral Bone (Triquetrum) Ulna; Change Current View Angle. The flexor retinaculum is the continuation of the deep fascia of the forearm which attaches to the carpal bones. Transverse section across the wrist (palm on top, thumb on left). The trapezium is involved in many small motions over time due to how frequently most individuals use their thumbs. The opponens pollicis muscle extends from the trapezium bone of the wrist and the flexor retinaculum in the heel of the hand to wrap partially around, and attaches to the first metacarpal bone. The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans. It is situated between the first metacarpal or the lowest bone in the thumb, and the scaphoid, with trapezoid at its side [6, 7]. styloid process of ulna. It may be known by its wedge-shaped form, the broad end of the wedge constituting the dorsal, the narrow end the palmar surface; and by its having four articular facets touching each other, and separated by sharp edges. This paper presents a case of an isolated dislocation of the trapezium without fracture, managed with closed reduction and percutaneous wiring, resulting in a good functional outcome. Like the other carpal bones, its ossification begins earlier in girls [8]. It moves the scapula and supports the arm . Due to its rarity, standard treatment has not been established. Distally, capitate bone articulates mainly along with the base of the third metacarpal and a small portion of the fourth. The scaphoid is situated between the proximal and distal rows of carpal bones.It is located on the radial side of the wrist, and articulates with the radius, lunate, trapezoid, trapezium and capitate. Search Bing for all related images. The inferior surface articulates with the proximal end of the second metacarpal bone; it is convex from side to side, concave from before backward and subdivided by an elevated ridge into two unequal facets. The superior, or upper, surface of the trapezium is an irregular shape that is smooth and touches another wrist bone called the scaphoid. It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand. styloid process. If there is sustained pain in the wrist and hand after punching, combined trapezoid and scaphoid fractures should be considered as the possible injury. The trapezoid begins to ossify around the same time as the scaphoid and trapezium, becoming visible on an x-ray image between the ages of 4 and 6 years [7]. It is the second bone from the thumb in the distal carpal row, located between the trapezium and capitate [5, 6]. Open reduction and internal fixation of the trapezoid was carried out using Kirschner wires. Sussex Hand Surgery What are the main risks of this operation?

The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans. The right and left trapezius together form a trapezium, an irregular four-sided figure. Structure of the capitate. The bone resembles a four-sided table in the geometrical shape of a trapezoid, with its dorsal side (on the side of the back of the hand) being two times wider than its palmar side, leading to its name [4]. The trapezoid is shaped like a wedge. transverse fracture. The trapezius muscle extends from the occipital bone (located at the base of the skull) to the middle of the back. Inferomedially however, it sometimes also articulates with the second metacarpal bone. Trip Database; TrendMD; Ontology: Trapezoid bone structure (C0223741) Definition (NCI) A carpal bone located between the trapezium and capitate bones.

A wide range of treatments are possible, including rest, surgery and casting. The trapeziotrapezoid, scaphotrapezoidal, and capitotrapezoid ligaments provide the primary ligamentous attachments [12], while the dorsal transverse intercarpal, as well as the dorsal and volar carpometacarpal ligaments, also attach with the trapezoid [10]. The human skeletal system functions include giving the body with structure, flexibility, protection and to provide attachments for muscles, to produce movement. Radiographic features. On the lateral surface, there is a smooth convex facet that articulates with the trapezium [10]. In this paper we introduce a new class of trapezoids by cutting diagonals of Gog and GOGAm triangles on the left instead of the right.
