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 ...
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 Galeazzi fracture is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint.It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint; the injury disrupts the forearm axis joint.
Olecranon fracture is a fracture of the bony portion of the elbow.The injury is fairly common and often occurs following a fall or direct trauma to the elbow. The olecranon is the proximal extremity of the ulna which is articulated with the humerus bone and constitutes a part of the elbow articulation.
Injuries to the distal radioulnar articulation often result from falls onto an outstretched hand. Injury can occur with concurrent fracture of the distal radius, the ulna, or can be isolated. For the upper limit of the distal radioulnar distance, sources vary between 2 mm [ 6 ] and 5 mm. [ 7 ] A classification system has been proposed by ...
Isolation exercises, or single-joint movements that focus on just one muscle at a time, can be essential for building muscle and strength in your workouts. Isolation exercises, or single-joint ...
Ulnar nerve is most commonly injured in the flexion type of injury because it crosses the elbow below the medial epidcondyle of the humerus. [ 3 ] A puckered, dimple, or an ecchymosis of the skin just anterior to the distal humerus is a sign of difficult reduction because the proximal fragment may have already penetrated the brachialis muscle ...
The ulnar nerve can suffer injury anywhere between its proximal origin of the brachial plexus all the way to its distal branches in the hand. It is the most commonly injured nerve around the elbow. [ 9 ] [ 10 ] Although it can be damaged under various circumstances, it is commonly injured by local trauma or physical impingement ("pinched nerve").
