What is the trapezium scaphoid?

The trapezium sits up against two other bones in your wrist, the scaphoid and trapezoid bones. Together these three bones form the Scapho-Trapezio-Trapezoid Joint (STT joint or STTJ). This joint can also be involved with arthritis, or rarely can be affected in isolation.The trapezium sits up against two other bones in your wrist, the scaphoid and trapezoid bones.

Trapezio

The trapezium is an irregular-shaped carpal bone found within the hand. The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb. On its ulnar surface are found the trapezoid and scaphoid bones.

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.

What is a trapezium fracture?

Trapezium fractures account for 3% to 5% of all carpal fractures. ²⁹. 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.

What does a fractured trapezium feel like?

Patients with trapezoid fractures may complain of point tenderness at the base of the second metacarpal, pain with range of motion at the second metacarpophalangeal joint, or pain and tenderness at the anatomic snuffbox. Patients may or may not have dorsal wrist swelling and decreased range of motion at the wrist.

Is it easy to break your trapezium?

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].

Why does my trapezium 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.

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. The angularly shaped four-sided bone resembles and gets its name from the geometric shape trapezium.

What does Trapeziectomy mean?

(a) Trapeziectomy

This is the most common form of surgery and involves a complete removal of the trapezium. Some surgeons fill the gap left by the removed bone using a piece of tendon from your wrist. To fill the space left, you may be given an artificial metal and plastic joint, or a silicone rubber spacer.

What type of bone is the trapezoid?

Can you break your trapezoid in your hand?

Isolated fractures of the trapezoid are rare. Of all of the fractures of the carpus, the most common is the scaphoid, which represents 68.2% of all carpal fractures (Papp, Orthop Clin N Am 38:251–60, 2007). In contrast, trapezoid fractures represent 0.4% of all carpal injuries.

How do I know if I broke my trapezium?

A Robert's AP view, with the hand in full pronation, is a good way of visualising the trapezium on plain radiographs. If the diagnosis is still in question Computerised Tomography or bone scintigraphy is recommended [2]. It is important to determine the stability of the joint before treatment.

Do you need a cast after thumb surgery?

The surgery is typically performed on an outpatient basis, and you will go home the same day.
