The trapezium and trapezoid are collectively known as the multangulars. This fracture often is as a result of trauma due to falling on the wrist directly or on outstretched hands. However, fractures of the trapezoid are rarely seen. A common clinical problem encountered with scaphoid fractures is delayed diagnosis. Trapezoid fractures occur when the second metacarpal butts up against it. A rare isolated trapezoid fracture. 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. Trapezoid fractures are uncommon in sports. A Scaphoid fracture is the most common wrist fracture. 3 (4): 372-4. Common symptoms reported by people with trapezium fracture A fracture of the carpal trapezoid bone ; Anatomy. USA.gov. 1. hand fractures [1].Among carpal bone fractures, scaphoid fracture is the most common, constituting 68-79% [2, 3]. Fractures of the carpal bones involve only a single bone or complex bones with or without ligament rupture. It is conservatively treated without dislocation. This is the most common location for a fracture. Check for errors and try again. Carpal bone fractures involve the eight bones that form the wrist. The authors present a single bone fracture of the trapezoid in a 40-year-old man. The incidence of trapezoid fractures is exceedingly rare, occurring in less than 1% of carpal fractures. Introduction . The trapezoid is the least commonly fractured or even injured among the wrist bones, accounting for only about 2% of all carpal fractures. Scaphoid fracture is the most common carpal fracture, occurring predominantly in active men with a peak prevalence in the 2nd to 3rd decades (, 8). 2019 Sep 5;2019:7949754. doi: 10.1155/2019/7949754. We presented a rare case of a trapezoid fracture associated with a scaphoid fracture caused by punching a ball in a football goalkeeper. A trapezoid fracture is a break in the trapezoid bone of the wrist. However, we are aware of no previous reports of occult fracture of the trapezoid bone, such as was described in this paper. 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. eCollection 2019. 2. Nondisplaced fracture of trapezoid [smaller multangular], unspecified wrist, initial encounter for closed fracture. A fracture in the trapezium bone is usually due to a fall with an outstretched hand or an injury to the wrist. Anatomically, the trapezoid is keystone in shape with a dorsal surface width twice that of its palmar surface. The trapezium articulates with two of the carpal bones, the scaphoid, and the trapezoid as well as with the first metacarpal bone [7].. The carpal bones are 8 small bones which make up the wrist. A displaced fracture of the scaphoid occurs when the bones have shifted out of position. We reviewed case notes regarding mechanism of injury, fracture pattern, mode of diagnosis, and time to diagnosis and treatment. Fracture of the trapezoid bone: A case report ☆. When the trapezoid is fractured, the mechanism is usually a high-energy axial blow to the second metacarpal. The trapezoid bone has a very stable position within the wrist, forming a relatively immobile joint with the second metacarpal base distally. 2. People with trapezoid fractures tend to … The fracture may be complicated in the acute phase by neurovascular injury, or in the subacute or chronic phases by nonunion, malunion, infection, osteonecrosis, or osteoarthritis. The authors present a single bone fracture of the trapezoid in a 40-year-old man. Trapezoid fractures occur when a strong bending or axial force is applied to the second metacarpal base. However, fractures of the trapezoid are rarely seen. It has been reported that less than half of cases were improperly diagnosed at initial hospital visit, with the trape-zoid fracture in one patient having been identified only after 99 days [10]. Clipboard, Search History, and several other advanced features are temporarily unavailable. Results: We treated 11 patients for trapezoid fractures over the 10-year period. Any of the carpal bones can break, causing a broken wrist. Carpal Fractures Other than Scaphoid in the Athlete. Isolated fracture of the trapezoid bone is due to axial loading on the outstretched palm and extended wrist, transmitted through the second metacarpal bone.... DOAJ is a community-curated online directory that indexes and provides access to high quality, open access, peer-reviewed journals. Axial force, while applied to the second metacarpal base, can cause the trapezoid bone structure to become injured or even to fracture. Closed fracture of trapezoid bone [smaller multangular] of wrist Short description: Fx trapezoid bone-closed. Given the wedged shape and weaker dorsal ligamentous support, fractures will dislocate in the dorsal direction 2. Carpal bones fractures comprise upwards of 8 percent of hand fractures . ICD-9-CM 814.06 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 814.06 should only be used for claims with a date of service on or before September 30, 2015. However, fracture of the trapezoid seemed to occur when the wrist joint was forced with excessive flexion stress that was placed on the trapezoid through the second metacarpal bone indirectly. BACKGROUND:Trapezoid fractures are very uncommon, accounting for less than 1% of all wrist fractures. The shape and size of this bone and its location below the thumb cause the integrity of the trapezium to deteriorate over time. 2019 Fall;19(3):271-275. doi: 10.31486/toj.18.0157. 2016 Dec 13;6(4):879. doi: 10.4081/cp.2016.879. 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]. However, fracture of the trapezoid seemed to occur when the wrist joint was forced with excessive flexion stress that was placed on the trapezoid through the second metacarpal bone indirectly. Isolated fractures are rarely seen and usually related to the high energy trauma. In this report, we describe a rare case of isolated trapezoid fracture encountered clinically. The trapezium bone is a small oblong bone which plays a role in the stability of the carpal tunnelas well as the stability of the thumb joint. 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. To date, few articles have been published on isolated trapezoid fractures. To our knowledge and based on a literature review, this is the first report of a true isolated trapezoid fracture without accompanying dislocation and without associated metacarpal, carpal, or distal radial fractures. Fractures of the lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate bones are the focus of this article. NLM An Occult Fracture of the Trapezoid Bone A Case Report.

They typically occur as the result of axial force through the second metacarpal. fracture displacement corresponds to fracture location (e.g. They account for ~0.4% of all carpal fractures 1. Occult fracture of the trapezoid bone: a report on two cases. It is often associated with a second metacarpal fracture. Common symptoms. Treatment varies from conservative management to open reduction internal fixation, failure to recognize can lead to functional problems such as decreased grasp power 2. Common symptom. Compound Dorsal Dislocation of Lunate with Trapezoid Fracture. In this type of fracture, the bone fragments have moved out of their normal position. A Scaphoid fracture is the most common wrist fracture. 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). 1 Among the carpal bones, the trapezoid bone is the least likely to be fractured, owing to its stability provided by strong ligamentous attachments. It is also connected by very strong ligaments to the trapezium, capitate and, scaphoid. The trapezoid is the carpal bone least often fractured, comprising approximately 2 percent of all carpal fractures [ 1-4 ]. They typically occur as the result of axial force through the second metacarpal. The trapezoid is the least commonly fractured carpal bone. This fracture typically occurs due to direct trauma to the hand or wrist. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The injury in our patient may have been a stress fracture or a nonunion of an initial dorsal intra-articular fracture. They can either occur in isolation or combination with another carpal bony injury. The trapezium articulates with two of the carpal bones, the scaphoid, and the trapezoid as well as with the first metacarpal bone [7].. The trapezoid bone has a very stable position within the wrist, forming a relatively immobile joint with the second metacarpal base distally. The trapezoid is in a relatively immobile, and protected location hence the rarity of an isolated fracture. Being surrounded by the trapezium, capitate, scaphoid, and the second metacarpal, it is often sheltered from minor blows and injuries. extra-articular vs. intra-articular) fracture pattern (e.g. Rita M. Sadowski, Richard D. Montilla. Because of its well-protected position in the wrist, traumatic lesions of the trapezoid bone are rare.  |  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]. A nondisplaced scaphoid fracture means that the bone has not shifted at all out of position, and the fracture may not even be visible on an x-ray image. The mechanism for development of fracture of the trapezoid alone is unknown. 814.06 is a legacy non-billable code used to specify a medical diagnosis of closed fracture of trapezoid bone [smaller multangular] of wrist. The trapezoid is only 0.2% of all carpal fractures. {"url":"/signup-modal-props.json?lang=us\u0026email="}. This code was replaced … Trapezoid fractures usually occur in association with other injuries, most commonly … fracture or dislocation. A tomogram of the carpal bone was useful in diagnosing the trapezoid fracture. Results: We treated 11 patients for trapezoid fractures over the 10-year period. Isolated fractures are rarely seen and usually related to the high energy trauma. The injury is usually the result of high-velocity force pushing the index metacarpal into the trapezoid, causing either a fracture or a fracture-dislocation of the trapezoid. Trapezium Bone Anatomy and Structure Surfaces and Articulation. Afifi N, Lu JJ. Yamamoto T, Matsushita T, Ito K, Matsushima S, Yoshida K, Kuroda R. Case Rep Orthop. A trapezoid fracture is a break in the trapezoid bone of the wrist. What causes a Wrist Fracture? The next common is a Triquetrum fracture. 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. A correct diagnosis was made in 5 cases on initial evaluation. Trapezoid fractures are an uncommon carpal fracture. The trapezium bone is located in the hand closest to the base of the thumb. HHS The mechanism of trapezoid injury is thought to be axial disruption 9 , 10 . Typically, the injury is due to hyperextension. Nondisplaced fracture of trapezoid [smaller multangular], unspecified wrist, initial encounter for closed fracture. 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).

Scaphoid fractures are classified according to the severity of displacement--or how far the pieces of bone have moved out of their normal position: Non-displaced fracture. Carpal fracture (1) is a medical condition where a carpal bone gets fractured. A trapezium fracture requires a direct blow to the wrist when the thumb is adducted. trapezoid fracture on plain radiographs is generally difficult, as the trapezoid is small and overlaps with other carpal bones. The trapezoid bone has a very stable position within the wrist, forming a relatively immobile joint with the second metacarpal base distally. We describe a case of an isolated trapezoid fracture that was managed nonoperatively with a favorable clinical outcome. How bad it is. NIH Fractures can also occur at both the proximal and distal ends of the bone. 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. This occurred in the same manner that a walnut is broken with nutcrackers. This fracture typically occurs due to direct trauma to the hand or wrist. Introduction.

In this report, we describe a rare case of isolated trapezoid A tomogram of the carpal bone was useful in diagnosing the trapezoid fracture. 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. Displaced fracture. Background: The trapezoid is the least commonly fractured carpal bone, comprising 4% of all carpal fractures. The carpal bones are 8 small bones which make up the wrist. Approach to Isolated Trapezoid Fractures. Fig 3 Trapezoid rotational bone graft osteotomy: (A) initial length of the metacarpal bone, (B) malunion with angular deformity of α° and shortening of the bone (a).

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. Because the trapezoid is fastened to the trapezium, capitate, and scaphoid by strong ligaments, fracture or dislocation is limited by this rigid fixation. They are the Scaphoid, Hamate, Lunate, Trapezium, Trapezoid, Capitate and Pisiform. Trapezoid fractures are uncommon in sports. Trapezoid Fracture Associated with Scaphoid Fracture in a Football Goalkeeper. The trapezoid is the most rarely fractured carpal bone. Illustration and x-ray showing a break in the mid-portion, or "waist," of the scaphoid. Isolated trapezoid fracture: four cases of a rare fracture on MRI.

Scaphoid fracture as a "puncher's fracture". We reviewed case notes regarding mechanism of injury, fracture pattern, mode of diagnosis, and time to diagnosis and treatment. In this type of fracture, the bone fragments line up correctly. 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 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]. Because the trapezoid is fastened to the trapezium, capitate, and scaphoid by strong ligaments, fracture or dislocation is limited by this rigid fixation. Horii E, Nakamura R, Watanabe K, Tsunoda K.
