What is the most common carpal bone to fracture?

Of the carpal elements, bones in the proximal row are the most frequently fractured. Scaphoid fracture is by far the most common carpal bone fracture, representing 60-70% of fractures in the carpal group and 10% of all hand fractures. Triquetral fracture is the second most common, accounting for 14% of wrist injuries.

A scaphoid (navicular) fracture is a break in one of the small bones of the wrist. Because portions of the scaphoid have a poor blood supply—and a fracture can further disrupt the flow of blood to the bone—complications with the healing process are common.

Also, what is the least common bone to break? Fractures of the upper arm, or humerus, are the least common.

Moreover, how are carpal fractures treated?

Treatment. Treatment of traumatic isolated nondisplaced body fractures or dorsal avulsion fractures is short arm cast immobilization for 3 to 6 wk, with reexamination and reimaging to demonstrate healing and appropriate carpal alignment (28,33).

How do you tell if your scaphoid is broken?

The most common signs and symptoms of a scaphoid fracture include pain, swelling and tenderness over the thumb side of the wrist. There is noticeable tenderness to the touch over the “anatomical snuff box.” Crunchiness and pain with gripping motions are also common symptoms that may be found with such an injury.

Do scaphoid fractures show up on xrays?

Special scaphoid view X-rays taken with your hand and wrist in a certain position may help to show up a scaphoid fracture. However, about 2 in every 10 scaphoid fractures may not be seen on X-ray at first. In some cases, a scaphoid fracture will not show up on an X-ray until around 10-14 days after the initial injury.

Can you move your hand with a scaphoid fracture?

A scaphoid fracture causes tenderness directly over the bone. The pain may increase when you move your thumb or grip things. Your initial pain may decrease over days or weeks. Scaphoid fractures usually do not cause bruising or significant swelling, which is the reason they are often mistaken for a sprained wrist.

Is a scaphoid fracture serious?

When not treated with immobilization right away, the fracture may fail to heal. This is called nonunion, and it can cause serious long-term complications. About 5 percent of scaphoid fractures are nonunion. Avascular necrosis can also cause nonunion.

Can you fracture wrist without knowing?

Without treatment, your broken finger may stay stiff and painful. Sometimes a bone can break without you realizing it. Many people with a fractured scaphoid think they have a sprained wrist instead of a broken bone because there is no obvious deformity and very little swelling.

Can a scaphoid fracture heal in 4 weeks?

Early diagnosis and treatment is critical to avoid short- and long-term complications of scaphoid fractures. Scaphoid fractures that are treated within 4 weeks from injury have a significantly higher union rates than in those whose treatment begins after 4 weeks [14].

What happens if a scaphoid fracture is left untreated?

If a Scaphoid fracture does not heal, it is called a Scaphoid Fracture Non-union. If left untreated, the part of the Scaphoid that interacts with the Radius may die, which can lead to painful arthritis in the wrist, developing months to years after the initial injury.

What is the fastest way to heal a scaphoid fracture?

Advance therapy with gentle AROM of the wrist and gentle opposition and flexion/extension exercises to the thumb. Continue elbow and shoulder exercises. Remove the short-arm cast at 6 weeks if the fracture appears to be radiographically healed. Use a wrist splint for protection.

What does a broken carpal feel like?

A broken wrist might cause these signs and symptoms: Severe pain that might worsen when gripping or squeezing or moving your hand or wrist. Swelling. Obvious deformity, such as a bent wrist.

How long does a carpal fracture take to heal?

In general, wrist fractures take at least a month to heal. While mild fractures can heal within a month or two, more serious ones can take up to a year to fully heal.

How is a Triquetral fracture treated?

The triquetrum is the most commonly fractured carpal bone. Dorsal cortical fractures may be treated with cast immobilization for 6 weeks. If un-united cortical fragments remain symptomatic, excision may be necessary. Triquetral body fractures are usually nondisplaced and heal well with cast immobilization for 6 weeks.

What is a Triquetrum fracture?

Triquetral fractures are carpal bone fractures generally occuring on the dorsal surface of the triquetrum. The triquetral may be fractured by means of impingement from the ulnar styloid, shear forces, or avulsion from strong ligamentous attachments.

Is it possible to fracture a carpal bone?

Other carpal bones are very rarely fractured. Fracture can occur with a powerful direct force, and multiple fractures are possible. Undisplaced fractures are usually treated conservatively. Surgery is often required for displaced fractures.

What is the Triquetrum bone?

The triquetrum refers to a part of the wrist known as the triquetral bone. Specifically, the bone is part of the carpus, a group of eight wrist bones. The triquetrum and other bones in the carpus are located between the two major bones in the forearm, the radius and ulna.

Is a chipped bone considered a fracture?

There’s no difference. A fracture is any loss of continuity of the bone. Anytime the bone loses integrity—whether it’s a hairline crack barely recognizable on an x-ray or the shattering of bone into a dozen pieces—it’s considered a fracture. A broken bone is a fractured bone and vice versa.
