Fractures and dislocations of the hand and wrist are common
injuries that can result from various traumatic events, such as falls, sports
injuries, or accidents. They can cause significant pain, swelling, and limited
mobility, affecting the ability to perform everyday tasks. Here's an overview
of fractures and dislocations of the hand and wrist:
Fractures of the Hand:
- Boxer's Fracture: A
boxer's fracture refers to a fracture of the fifth metacarpal, which is
the bone that connects the Pinky finger to the wrist. It typically occurs
due to a direct impact, such as punching a hard object with a clenched
- Bennett's Fracture: A
Bennett's fracture is a type of fracture that affects the base of the
first metacarpal bone, near the wrist joint. It usually occurs from a
forceful axial load on the thumb.
- Scaphoid Fracture: The
scaphoid is a small bone located near the base of the thumb. Fractures of
the scaphoid are common and can occur when falling onto an outstretched
Dislocations of the Hand:
- Finger Dislocations:
Dislocations can occur in any of the fingers, where the bones forming the
finger joint are displaced from their normal positions.
- MCP Dislocation: MCP
(metacarpophalangeal) dislocation happens when there is an injury to the
joint connecting the metacarpal bone to the proximal phalanx (the bone
closest to the palm) of a finger.
- Carpal Dislocation:
Carpal bones are the small bones in the wrist. Dislocations in the wrist
can occur due to high-energy trauma.
Fractures of the wrist:
Fracture: Colles' fracture is one of the most common types of wrist
fractures. It involves the distal end of the radius, the larger bone in
the forearm. The fracture typically occurs about an inch from the wrist
joint and is usually the result of a fall onto an outstretched hand.
Fracture: A Smith's fracture, also known as a reverse Colles' fracture, is
a fracture of the distal end of the radius but in an opposite direction to
Colles' fracture. It usually results from a fall onto a flexed hand.
Fracture: The scaphoid is one of the carpal bones located on the thumb
side of the wrist. Fractures of the scaphoid are common and can be tricky
to diagnose due to their location and subtle symptoms.
Fracture: Barton's fractures involve the distal end of the radius and are
often associated with dislocations of the wrist joint.
Fracture: This fracture affects the radial styloid process, a bony
prominence on the thumb side of the wrist, and is usually caused by a
direct blow to the hand.
In some cases, the wrist fracture can be associated with a dislocation of
one or more carpal bones, leading to a more complex injury.
To promote healing, the injured hand or finger may be immobilized by your
hand therapist using splints, casts, or braces.
In cases of dislocation, a doctor might need to perform a reduction
procedure to realign the bones manually.
Some fractures and complex dislocations may require surgical intervention
to stabilize the bones and promote proper healing.
Therapy: After the initial healing period, Hand therapy exercises can help
regain strength, flexibility, and function in the hand.
Management: Pain relief medications or injections may be prescribed to
manage pain and inflammation.
- It's essential to seek medical attention promptly if you
suspect a hand fracture or dislocation. Proper diagnosis and treatment are
crucial to avoid complications and ensure optimal recovery. After receiving
medical care, following the doctor's instructions and adhering to the
rehabilitation process will aid in restoring hand function and reducing
