A scaphoid fracture is a break of the scaphoid bone in the wrist. [1] Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. [ 2 ] The anatomic snuffbox is generally tender and swelling may occur. [ 2 ]
In metaphyseal areas, delayed signs of fracture include a band of sclerosis perpendicular to the trabeculae, while diaphyseal fractures may present as periosteal thickening. [1] Digital radiography known as tomosynthesis has been shown to be superior to conventional radiographs in the detection of occult fracture of the scaphoid.
Scaphoid fracture, distal radial fractures, avascular necrosis of the scaphoid, gout, pseudogout, rheumatoid arthritis, Kienbock disease, lunate fracture vs dislocation dorsal intercalated segmental instability: Treatment: Non-surgical and surgical (fusion, joint replacement)
Scapholunate advanced collapse is the most common form, followed by scaphoid non-union advanced collapse (SNAC). [3] Other post-traumatic causes such as intra-articular fractures of the distal radius or ulna can also lead to wrist osteoarthritis, but are less common.
Preiser disease, or avascular necrosis of the scaphoid, is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture.It is thought to be caused by repetitive microtrauma or side effects of drugs (e.g., steroids or chemotherapy) in conjunction with existing defective vascular supply to the proximal pole of the scaphoid.
Clinical appearance of acrosclerotic piece-meal necrosis of the thumb in a patient with systemic sclerosis. Systemic scleroderma in the limbs, showing carcinoma subsequent to ulceration. In the skin, systemic sclerosis causes hardening and scarring. The skin may appear tight, reddish, or scaly. Blood vessels may also be more visible.
Chauffeur's fracture, also known as Hutchinson fracture, is a type of intraarticular oblique fracture of the radial styloid process in the forearm. [1] 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.
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 ...
