It typically occurs as a result of a fall on an outstretched hand. [2] Risk factors include osteoporosis. [2] The diagnosis may be confirmed via X-rays. [2] The tip of the ulna may also be broken. [4] Treatment may include casting or surgery. [3] Surgical reduction and casting is possible in the majority of cases in people over the age of 50. [5]
Direct blow on back of upper forearm would be a very uncommon cause. In this context, isolated ulnar shaft fractures are most commonly seen in defence against blunt trauma (e.g. nightstick injury). Such an isolated ulnar shaft fracture is not a Monteggia fracture. [citation needed] It is called a 'nightstick fracture'.
The most common cause of this type of fracture is a fall on an outstretched hand from standing height, although some fractures will be due to high-energy injury. People who fall on the outstretched hand are usually fitter and have better reflexes when compared to those with elbow or humerus fractures. The characteristics of distal radius ...
Fractures of scaphoid can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand. Using the Herbert classification system, there are three main types of scaphoid fractures. 10%-20% of fractures are at the proximal pole, 60%-80% are at the waist (middle), and the ...
The dislocation of ulnar head in Galeazzi fracture dislocation may be dorsal (commoner) or volar (rare) depending on the mechanism of injury. If the fall is on the outstretched hand with forearm in pronation, the dislocation is dorsal, and if forearm is in supination at the time of injury, the dislocation is volar.
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius. It can be caused by falling onto an outstretched hand. Treatment is often open reduction and internal fixation, which is surgical realignment of the bone fragments and fixation with pins, screws, or plates.
The mechanism of injury is most commonly due to fall on an outstretch hand. [3] Extension type of injury (70% of all elbow fractures) is more common than the flexion type of injury (1% to 11% of all elbow injuries). [4] Injury often occurs on the non-dominant part of the limb. Flexion type of injury is more commonly found in older children.
