  2. Scaphoid fracture - Wikipedia

    en.wikipedia.org/wiki/Scaphoid_fracture

    Fracture of the tubercle of the scaphoid bone of the wrist. Scaphoid fractures are often diagnosed using plain radiographs and multiple views are obtained as standard. [9] However, not all fractures are apparent initially. [7] In 1/4 of cases, the clinical examination suggests a fracture, but the X-ray does not show it, even though there is ...

  4. Anatomical snuffbox - Wikipedia

    en.wikipedia.org/wiki/Anatomical_snuffbox

    Blood enters the scaphoid distally. Consequently, in the event of a fracture the proximal segment of the scaphoid will be devoid of a vascular supply, and will—if action is not taken—avascularly necrose within a sufferer's snuffbox. Due to the small size of the scaphoid and its shape, it is difficult to determine, early on, whether or not ...

  5. Wrist osteoarthritis - Wikipedia

    en.wikipedia.org/wiki/Wrist_osteoarthritis

    When the X-ray is diagnostic and there is a convincing Terry Thomas sign it is a static scaphoid instability. When the scaphoid is made unstable by either the patient or by manipulation by the examining physician it is a dynamic instability. [11] SNAC. In order to diagnose a SNAC wrist you need a PA view X-ray and a lateral view X-ray.

  6. Scaphoid bone - Wikipedia

    en.wikipedia.org/wiki/Scaphoid_bone

    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.

  7. Terry-Thomas sign - Wikipedia

    en.wikipedia.org/wiki/Terry-Thomas_sign

    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. This burst causes the scaphoid bone to dorsally rotate. [3]

  8. Chauffeur's fracture - Wikipedia

    en.wikipedia.org/wiki/Chauffeur's_fracture

    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.

  9. Preiser disease - Wikipedia

    en.wikipedia.org/wiki/Preiser_disease

    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.
