What type of fracture results from the radius and ulna being forced backwards and upwards?
Although rare, a true Colles fracture is a transverse fracture of the radius, 1.57 in (4 cm) proximal to the wrist joint with backward, upward, and outward displacement of the distal fragment.
Which of the following is the most common cause of wrist sprains *?
Falling on an outstretched hand is one of the most common causes of a wrist sprain. Several factors may cause stretching and/or tearing of ligaments in the wrist. A few examples include: Falls.
Which of the following is associated with a Colles fracture?
The Colles fracture is defined as a distal radius fracture with dorsal comminution, dorsal angulation, dorsal displacement, radial shortening, and an associated fracture of the ulnar styloid.
Which bone in the wrist is most commonly dislocated quizlet?
Lunate is most commonly dislocated carpal, moves anteriorly. Scaphoid is 2nd most commonly dislocated carpal, moves anterior, lateral, and turns on end.
What motion would cause pain and be indicative of a scaphoid fracture?
Scaphoid fractures usually cause pain and swelling in the anatomic snuffbox and on the thumb side of the wrist. The pain may be severe when you move your thumb or wrist, or when you try to pinch or grasp something.
What causes mallet finger?
In a mallet injury, when an object hits the tip of the finger or thumb, the force of the blow tears the extensor tendon. Occasionally, a minor force such as tucking in a bed sheet will cause a mallet finger.
How do I know what type of wrist injury I have?
The angle at which the wrist hits the ground may determine the type of injury. The more the wrist is bent back (extension), the more likely the scaphoid bone will break. With less wrist extension it is more likely the lower arm bone (radius) will break. Scaphoid fractures are not always immediately obvious.
Which bone in the wrist is most commonly dislocated?
The most common carpal dislocations are the lunate, the lunate with a scaphoid fracture, and perilunate dislocation. Perilunate dislocations result from dislocation of the distal carpal row. Scaphoid fractures often accompany perilunate dislocation.
What is the commonest complication of Colles fracture?
Complications include 1-3: malunion resulting in dinner fork deformity. median nerve palsy and post-traumatic carpal tunnel syndrome. reflex sympathetic dystrophy.
Do Colles fractures require surgery?
This type of injury occurs more often in older people with brittle bones, and in children, whose bones tend to be soft. It can be treated successfully with surgery, although recovery may be slow.
Where do you feel pain with a scaphoid fracture?
How serious is a scaphoid fracture?
A scaphoid fracture can lead to wrist osteoarthritis, especially if the fracture is untreated and does not heal correctly. This is called “nonunion.” Severe cases of this kind of osteoarthritis can lead to an incorrect alignment of wrist bones in what is called scaphoid nonunion advanced collapse (SNAC).
What is the medical term for a broken wrist?
Wrist Fracture A wrist fracture is a medical term for a broken wrist. The wrist is made up of eight small bones which connect with the two long forearm bones called the radius and ulna. Although a broken wrist can happen in any of these 10 bones, by far the most common bone to break is the radius.
Where does a distal radius fracture occur in the wrist?
Distal Radius Fracture (Wrist Fracture) Distal radius fractures are one of the most common types of bone fractures. They occur at the end of the radius bone near the wrist.
What do you call a non displaced wrist fracture?
This is called a distal radius fracture by hand surgeons (Figure 1). Some wrist fractures are stable. “Non-displaced” breaks, in which the bones do not move out of place initially, can be stable.
What happens to the wrist after a Colles fracture?
The side view of a wrist after a Colles fracture is sometimes compared to the shape of a fork facing down. There is a distinct “bump” in the wrist similar to the neck of the fork. It happens because the broken end of the distal radius shifts up toward the back of the hand.
