Results: We treated 11 patients for trapezoid fractures over the 10-year period. 2019 Sep 5;2019:7949754. doi: 10.1155/2019/7949754. Being surrounded by the trapezium, capitate, scaphoid, and the second metacarpal, it is often sheltered from minor blows and injuries. NIH COVID-19 is an emerging, rapidly evolving situation. dorsal intercalated segment instability (DISI), volar intercalated segment instability (VISI), scaphoid nonunion advanced collapse (SNAC), triangular fibrocartilaginous complex (TFCC) injuries, ulnar-sided wrist impaction and impingement syndromes, calcium pyrophosphate dihydrate deposition disease. When it does it is the result of a fall on an outstretched, dorsiflexed hand. The authors report two cases of isolated, undisplaced, fractures of the trapezoid bone. The trapezoid is the least commonly fractured carpal bone, with Sadowski and Montilla, 2008 reporting trapezoid fractures to account for 0.4% of all carpal injuries. eCollection 2020 Jun. Isolated fractures are rarely seen and usually related to the high energy trauma. There may be gaps between the pieces of bone or fragments may overlap each other. Introduction. It is conservatively treated without dislocation. Mechanisms of injury have typically been reported as an axial load, with or without forced wrist flexion/extension, that is transmitted from the second metacarpal indirectly to the trapezoid. A 19-year-old male who played as a football goalkeeper visited our hospital with complaints of sustained pain from the right wrist to the hand after punching a ball. (2008) HAND. Fractures of the trapezium are often associated with other fractures, mainly of the thumb metacarpal and the distal radius. Trapezoid fractures occur when a strong bending or axial force is applied to the second metacarpal base. They typically occur as the result of axial force through the second metacarpal. Nagumo, Akira MD; Toh, Satoshi MD; Tsubo, Kenji MD; Ishibashi, Yasuyuki MD; Sasaki, Tomoyuki MD Because of its well-protected position in the wrist, traumatic lesions of the trapezoid bone are rare. Trapezoid fractures are uncommon in sports. The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans.It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand. Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal. 1. A displaced fracture of the scaphoid occurs when the bones have shifted out of position. Afifi N, Lu JJ. An Occult Fracture of the Trapezoid Bone A Case Report. Carpal Bone Fractures. The carpal bones are 8 small bones which make up the wrist. The pisiform, a sesamoid bone nestled in the flexor carpi ulnaris tendon, rarely fractures. The trapezoid is the least commonly fractured carpal bone. Most trapezoid fractures were diagnosed on computed tomographic scan. On the other hand, trapezoid bone fracture is rare. Open in a separate window The patient was placed in a short arm cast for 6 weeks with the wrist in 20° of extension and the metacarpophalangeal and interphalangeal joints free and then progressed to a splint for the next 2 weeks. Nagumo, Akira MD; Toh, Satoshi MD; Tsubo, Kenji MD; Ishibashi, Yasuyuki MD; Sasaki, Tomoyuki MD Carpal bone fractures involve the eight bones that form the wrist. Disease Ontology - OBO (Open Biomedical Ontologies) Closed fracture of carpal bone, unspecified; Fracture of carpal bone(s) Computed tomography obtained due to concern for an occult fracture revealed a comminuted fracture of the trapezoid bone involving the articular surface with an anteriorly displaced bone fragment (Figures 1 and 2). Fractures to bones of the distal carpal row—comprising the trapezium, trapezoid, capitate, and hamate— are less frequent than fractures of bones in the proximal row (scaphoid, lunate, triquetrum, and pisiform).

This occurred in the same manner that a walnut is broken with nutcrackers. An open fracture; A fracture in which the bone pieces move before they heal; Loose bone fragments that could enter a joint; Damage to the surrounding ligaments, nerves or blood vessels; Fractures that extend into a joint; Even after reduction and immobilization with a cast or splint, your bones can shift. Would you like email updates of new search results? The trapezoid is in a relatively immobile, and protected location hence the rarity of an isolated fracture. A trapezoid fracture is a break in the trapezoid bone of the wrist. Given the wedged shape and weaker dorsal ligamentous support, fractures will dislocate in the dorsal direction 2. USA.gov. The mechanism for development of fracture of the trapezoid alone is unknown. The proximal surface of the trapezium, in combination with the surface of the trapezoid, forms a slightly concave facet for articulating with the distal surface of the scaphoid [11]. We report a case of an isolated, nondisplaced trapezoid fracture that was sustained by direct trauma and subsequently treated successfully in a short-arm cast. The protected position of the trapezoid between the base of the second metacarpal, capitate, trapezium, and scaphoid and the strong ligamentous attachments provide much stability, limiting the likelihood of an isolated fracture. The authors present a single bone fracture of the trapezoid in a 40-year-old man. Rita M. Sadowski, Richard D. Montilla.
