This fracture pattern is characterized by a break on one side of the bone while the other side remains intact and bends, similar to breaking a young, green tree branch. Greenstick fractures most commonly affect the long bones of the forearm (radius and ulna) but can also occur in other long bones throughout the body. Treatment generally ...
Displaced fractures of the ulnar styloid base associated with a distal radius fracture result in instability of the DRUJ and resulting loss of forearm rotation. [ citation needed ] Nerve injury, especially of the median nerve and presenting as carpal tunnel syndrome, is commonly reported following distal radius fractures.
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
Type 1: A fracture at the junction of the shaft and distal extremity of the radius (occurs only in children between the age of 1 and 15 years, and is most commonly a greenstick fracture) Type 2: Slipping of the epiphysis with dorsal displacement, often with a dorsally avulsed triangular fragment of the radius (occurs in the age range 10-20 years)
An ulna fracture is a break in the ulna bone, one of the two bones in the forearm. [2] It is often associated with a fracture of the other forearm bone, the radius. [1] [3]An ulna fracture can be a single break as in a so called nightstick fracture, which can be caused by someone being hit on the inside of the forearm often by a stick, notably when they are holding their arm up to protect ...
David Vassegh came out of the slide the wrong way, but even he couldn't help laughing about it.
The Sub-nanostructure of cortical bone may provide one possible explanation for the greenstick fractures in children. On the contrary to adults bone tissue, the low ratio between the mature and the immature enzymatic cross-links in children bone tissue is a potential explanation of the presence of greenstick fractures in children. [5]
The ulna fractures in the proximal one-third of the shaft due to extreme dislocation. Depending on the impact and forces applied in each direction, degree of energy absorption determines pattern, involvement of the radial head and whether or not open soft tissue occurs. Direct blow on back of upper forearm would be a very uncommon cause.
