Distal radius fractures are often associated with distal radial ulnar joint (DRUJ) injuries, and the American Academy of Orthopaedic Surgeons recommends that postreduction lateral wrist X-rays should be obtained in all patients with distal radius fractures in order to preclude DRUJ injuries or dislocations. [11]
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 ...
Galeazzi fracture after surgical fixation. Galeazzi fractures are best treated with open reduction of the radius and the distal radio-ulnar joint. [3] It has been called the "fracture of necessity," because it necessitates open surgical treatment in the adult. [4] Nonsurgical treatment results in persistent or recurrent dislocations of the ...
Fracture with a dorsal tilt. Dorsal is left, and volar is right in the image. There are a number of ways to classify distal radius fractures.Classifications systems are devised to describe patterns of injury which will behave in predictable ways, to distinguish between conditions which have different outcomes or which need different treatments.
The load transmission is directly proportional to this ulnar variance. In neutral ulnar variance, approximately 20 percent of the load is transmitted. With negative ulnar variance, the load across the TFC is decreased. This occurs during supination, because the radius moves distally on the ulna and creates a negative ulnar variance.
Delayed treatment of the radial head fracture will also lead to proximal migration of the radius. [3] The distal radio-ulnar joint dislocation can be reduced by supination of the forearm, and may be pinned in place for 6 weeks to allow healing of the interosseous membrane. [1]
Fractures of the styloid process of the ulna seldom require treatment when they occur in association with a distal radius fracture. The major exception is when the joint between these bones, the distal radioulnar joint (or DRUJ), is unstable. When the DRUJ is unstable, the ulnar styloid may require independent treatment.
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.
