Why is it called Colles fracture?
Named after Abraham Colles, who first described a distal radius fracture in 1814 at the Royal College of Surgeons in Dublin, the Colles fracture is one of the most common fractures encountered in orthopedic practice.
What is impaction in Colles fracture?
Colles fractures are very common extra-articular fractures of the distal radius that occur as the result of a fall onto an outstretched hand. They consist of a fracture of the distal radial metaphyseal region with dorsal angulation and impaction, but without the involvement of the articular surface.
What causes dinner fork deformity?
A dinner fork deformity, also known as a bayonet deformity, occurs as the result of a malunited distal radial fracture, usually a Colles fracture. The distal fragment is dorsally angulated, displaced and often also impacted.
Which artery is damaged in Colles fracture?
A Colles’ fracture is a type of fracture of the distal forearm in which the broken end of the radius is bent backwards. Symptoms may include pain, swelling, deformity, and bruising. Complications may include damage to the median nerve. It typically occurs as a result of a fall on an outstretched hand.
What is Barton’s fracture?
A Barton fracture is a compression injury with a marginal shearing fracture of the distal radius. The most common cause of this injury is a fall on an outstretched, pronated wrist.
Can Madelung deformity get worse?
Over time, the deformity can get worse resulting in break down of the joint and instability. Tendon rupture is possible in advanced cases.
What causes madelung?
The exact cause of Madelung’s disease is not fully understood. The body’s inability to properly metabolize fat indicates that it may be an endocrine disorder. One theory is that a defect in the adrenergic (epinephrine or norepinephrine)-stimulated fat breakdown (lipolysis) process results in improper deposition of fat.
Which nerve is affected in dinner fork deformity?
The Median Nerve is the most commonly injured and is usually compressed by the angulation of fragments. Proximal radioulnar joint subluxation or dislocation may also occur, making examination of the elbow important.
