The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
The scaphoid can be slow to heal because of the limited circulation to the bone. Fractures of the scaphoid must be recognized and treated quickly, as prompt treatment by immobilization or surgical fixation increases the likelihood of the bone healing in anatomic alignment, thus avoiding mal-union or non-union. [6] Delays may compromise healing.
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.
Hand fracture. Scaphoid fracture; Rolando fracture – a comminuted intra-articular fracture through the base of the first metacarpal bone; Bennett's fracture – a fracture of the base of the first metacarpal bone which extends into the carpometacarpal (CMC) joint [15] Boxer's fracture – a fracture at the neck of a metacarpal
In radiology, the Terry-Thomas sign is a scapholunate ligament dissociation on an anteroposterior view of the wrist. [1] [2] Most commonly a result of a fall on the outstretched hand (), the scapholunate ligament ruptures resulting in separation of the lunate and scaphoid bones.
Digital radiography known as tomosynthesis has been shown to be superior to conventional radiographs in the detection of occult fracture of the scaphoid. Tomosynthesis has the ability to demonstrate cortical, as well as moderately displaced trabecular fractures.
