The pisiform, a sesamoid bone nestled in the flexor carpi ulnaris tendon, rarely fractures. When the trapezoid is fractured, the mechanism is usually a high-energy axial blow to the second metacarpal. Because the trapezoid is fastened to the trapezium, capitate, and scaphoid by strong ligaments, fracture or dislocation is limited by this rigid fixation. They typically occur as the result of axial force through the second metacarpal. This fracture typically occurs due to direct trauma to the hand or wrist. Most trapezoid fractures were diagnosed on computed tomographic scan. The trapezoid bone (also known as the os trapezoideum or the lesser multangular) is the smallest carpal bone in the distal row, sitting lateral to the capitate. Fractures of the lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate bones are the focus of this article. Isolated fractures are rarely seen and usually related to the high energy trauma. Common symptoms reported by people with trapezium fracture.

The injury in our patient may have been a stress fracture or a nonunion of an initial dorsal intra-articular fracture. Isolated trapezoid fracture: four cases of a rare fracture on MRI. Trapezium fractures are uncommon carpal bone injuries. The trapezium is on the radial side of the distal carpal row, and articulates distally with the thumb metacarpal and proximally with the scaphoid and trapezoid (image 1 and figure 1 and figure 2 and figure 3). Because the trapezoid is fastened to the trapezium, capitate, and scaphoid by strong ligaments, fracture or dislocation is limited by this rigid fixation. The trapezoid is in a relatively immobile, and protected location hence the rarity of an isolated fracture. 1 Among the carpal bones, the trapezoid bone is the least likely to be fractured, owing to its stability provided by strong ligamentous attachments. We presented a rare case of a trapezoid fracture associated with a scaphoid fracture caused by punching a ball in a football goalkeeper. metacarpals and phalanges, carpal bone fractures account for approximately 8% of all hand fractures [1].Among carpal bone fractures, scaphoid fracture is the most common, constituting 68-79% [2, 3].

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]. A rare isolated trapezoid fracture. 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. 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.
