How do you know if your trapezium is fractured?
Trapezium fractures account for 3% to 5% of all carpal fractures. Fractures of this bone occur most commonly with a fall on a hyperextended and radially deviated wrist with the thumb in abduction. Clinically, there is point tenderness at the base of the thumb.
Can you break your trapezium bone?
The trapezium is rarely injured, representing about 4 percent of all carpal fractures [1-6]. When present, trapezium fractures often occur in association with other injuries, most commonly fracture of the first (thumb) metacarpal followed by other carpal bone injuries and the distal radius [7].
What does the trapezium bone do?
Due to the location of the trapezium below the thumb joint, the trapezium plays a role in both the stability and the movement of the thumb. The trapezium also touches two other bones in the wrist joint, the scaphoid and trapezoid bones.
Can you dislocate your trapezium?
Isolated dislocation of the trapezium is an uncommon injury. There are sixteen cases to date reported in the literature. The management of these cases has varied from complete excision to open or closed reduction, with or without percutaneous wiring.
What is the trapezium bone?
The trapezium bone is one of eight small bones which make up the wrist joint. The trapezium is the last bone in the row of wrist bones, located beneath the thumb joint. The trapezium bone along with the base of the thumb joint forms what is called a carpometacarpal joint, also known as a CMC joint.
Why does my trapezoid bone hurt?
Basal joint arthritis is one injury that is common to the trapezium/first metacarpal joint. It causes pain at the base of the thumb, particularly during pinching or gripping. It also results in weakness when pinching. This joint appears to be particularly prone to wear and tear from normal use of the hand.
What does it mean when your trapezium hurts?
Causes of trapezius pain Overuse: Pain in the trapezius often develops due to overuse. Repetitive activities that involve the shoulders can put stress on the muscle. These activities may include lifting heavy objects or participating in specific sports, such as swimming.
What bone classification is the trapezium?
The trapezium (Latin: Os trapezium) is one of the eight carpal bones in the human hand, classified as a short bone as all other wrist bones.
Why does my trapezium hurt?
What attaches trapezium?
The trapezium articulates with four bones. On the proximal side, it articulates with the scaphoid. On the medial side, it articulates with the trapezoid and second metacarpal. Distally it articulates with the first metacarpal.
How to diagnose a trapezium ridge fracture?
Trapezial ridge fractures may be overlooked at routine wrist radiography. Carpal tunnel radiographs may be helpful to detect this fracture 2, whereas CT imaging can be diagnostic.
What kind of fracture is a trapezial fracture?
Trapezial fractures are carpal fractures that often result from axial compression to the wrist. Diagnosis is confirmed with orthogonal radiographs of the wrist.
Can a non displaced trapezium fracture be occult?
Non displaced fractures can sometimes be occult. A Robert’s AP view, with the hand in full pronation, is a good way of visualizing the trapezium on plain radiographs. If the diagnosis is still in question, a CT or bone scintigraphy could be considered. Trapezial ridge fractures may be overlooked at routine wrist radiography.
Can a trapezium fracture cause carpal tunnel syndrome?
Resisted wrist flexion will typically aggravate the pain, and there may be associated carpal tunnel syndrome. The trapezoid is one of the smallest carpal bones; it is interposed between the trapezium and the capitate. The incidence of trapezoid fractures is exceedingly rare, occurring in less than 1% of carpal fractures.
