Which nerve is affected in Colles fracture?

Compressive neuropathy is one of the most important complications of Colles' fractures and usually involves the median nerve.

Which nerve is affected in Smith fracture?

Research suggests that up to 15% of Smith's fractures may show symptoms of acute carpal tunnel syndrome from compression to the median nerve. Both radial and ulnar nerve compression are less commonly involved.

What is the commonest complication of Colles fracture?

What are the complications of a Colles fracture? Wrist stiffness is the most common complication.

Which nerve is affected in distal radius fracture?

The mechanisms of ulnar nerve injury associated with distal radius fracture include: Severing of the nerve over the sharp edge of the fractured radius; entrapment in the distal radioulnar joint; encasement of the nerve in scar tissue leading to tardive neuropathy and displacement of the nerve dorsal to the ulnar ...

Which tendon gets involved in 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.

Colles Fracture Mnemonic

What is the mechanism for a Colles fracture?

Mechanism. Most Colles fractures are secondary to a fall on an outstretched hand (FOOSH) with a pronated forearm in wrist extension (the position one adopts when trying to break a forward fall).

What happens in a Colles fracture?

Technically, it's a break in the larger of the two bones in your forearm. The bone breaks on the lower end, close to where it connects to the bones of the hand on the thumb side of the wrist. Colles' fractures are very common; they're the most frequently broken bone in the arm.

Can a broken wrist cause nerve damage?

Injury to the nerves can occur when the hand, wrist, or finger is broken, crushed, overstretched, cut, or burned. It is the major cause of nerve damage to the hand and wrist.

What is the difference between Colles and Smith fracture?

Colles fracture. If you're diagnosed with a Colles fracture, the broken piece of your wrist bone (radius) points backward. Smith fractures are the opposite: The broken end of your bone points forward.

Can a broken wrist cause ulnar nerve damage?

In conclusion, ulnar nerve injury following wrist fracture is a rare condition, usually observed in young males and after high-impact trauma. The condition is often associated with severe dorsal displacement and open fracture.

What is another name for Colles fracture?

A Colles' wrist fracture occurs when the radius bone in your forearm breaks. It's also known as a distal radius fracture, transverse wrist fracture, or a dinner-fork deformity of the wrist. It's named after Abraham Colles, who wrote a paper on this type of fracture in 1814.

What is Corticocancellous Junction?

[kor″tĭ-ko-kan´sĕ-lus] referring to bony tissue containing both cortical and cancellous elements.

What is Colles fracture of the wrist?

A Colles fracture is a break in the radius close to the wrist. It was named for the surgeon who first described it. Typically, the break is located about an inch (2.5 centimeters) below where the bone joins the wrist. A Colles fracture is a common fracture that happens more often in women than men.

Is Colles or Smith fracture more common?

Smith fractures are the second most common type of distal radius fractures but are significantly less common than the Colles fracture.

What is Bennett's fracture?

Introduction. Bennett fracture is the most common fracture involving the base of the thumb. This fracture refers to an intraarticular fracture that separates the palmar ulnar aspect of the first metacarpal base from the remaining first metacarpal.

Which carpal fracture causes median nerve involvement?

Median nerve compression in the carpal tunnel is a common complication of a Smith fracture. Loss of this nerve function is manifested by the loss of thumb opposition and decreased sensation to the thumb, index finger, long finger, and radial half of the ring finger.

What is Jefferson fracture?

A Jefferson fracture is a bone fracture of the vertebra C1. The vertebra C1 is a bony ring, with two wedge-shaped lateral masses, connected by relatively thin anterior and posterior arches and a transverse ligament. The lateral mass on vertebra C1, who is taller, is directed laterally.

Which is the most famous fracture of the radius?

One of the most common distal radius fractures is a Colles fracture, in which the broken fragment of the radius tilts upward. This fracture was first described in 1814 by an Irish surgeon and anatomist, Abraham Colles — hence the name Colles fracture.

What nerves are in the wrist?

The three main nerves of the hand and wrist are the ulnar nerve, radial nerve and median nerve.

What can cause nerve damage in wrist?

Hand or wrist nerve injury risk factors

A severe blow, burn or cut, such as from a car accident, can cause a nerve injury. Repetitive use. Work tasks or other activities that put pressure on or stretch the nerve can cause nerve injuries. People who are prone to falling are also at greater risk of nerve injuries.

What nerves affect the hands?

Three nerves control function in our hands: the median, ulnar, and radial nerves. Each of these nerves is responsible for both sensory and motor function in different parts of the hand.

How do you diagnose a Colles fracture?

A physical exam by a doctor is necessary for an accurate fracture diagnosis. One or more sets of x-rays may be required to assess the severity of the breakage. There is also a small possibility that blood flow and nerves could be adversely affected by the fracture.

What causes Colles?

A Colles fracture usually happens when someone falls on to an outstretched arm. It can also occur as a result of trauma, such as occurs in a car, bike, or skiing accident. The age of the person can affect whether or not a Colles fracture occurs.

Why are Colles fractures common?

Colles fractures are most common as the result of a fall on an outstretched hand, or as the result of trauma. A Colles fracture requires the wrist be extended during the injury, while a fall on a flexed wrist would result in something called a Smith's fracture. How long does a Colles fracture take to recover?
