Scaphoid fracture. 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 ]
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.
The scaphoid is situated between the proximal and distal rows of carpal bones. It is located on the radial side of the wrist, [1]: 176 adjacent to the styloid process of the radius. [2] It articulates with the radius, lunate, trapezoid, trapezium, and capitate. [1]: 176 Over 80% of the bone is covered in articular cartilage. [3]
A scapular fracture is a fracture of the scapula, the shoulder blade. The scapula is sturdy and located in a protected place, so it rarely breaks. When it does, it is an indication that the individual was subjected to a considerable amount of force and that severe chest trauma may be present. [ 1 ] High-speed vehicle accidents are the most ...
To perform the test, the examiner grasps the wrist with their thumb over the scaphoid tubercle (volar aspect of the palm) in order to prevent the scaphoid from moving into its more vertically oriented position in ulnar deviation. For the test, the wrist needs to be in slight extension. The patient's wrist is then moved from ulnar to radial ...
The most common complication after surgery is pain persisting in the thumb. Over long term, there is pain relief, but on short term, patients experience pain from the surgery itself. The main complaint is a burning sensation or hypersensitivity over the incision. Some patients develop a complex regional pain syndrome. This is a syndrome of ...
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.
The midcarpal joint is formed by the scaphoid, lunate, and triquetral bones in the proximal row, and the trapezium, trapezoid, capitate, and hamate bones in the distal row. [1] The distal pole of the scaphoid articulates with two trapezial bones as a gliding type of joint. The proximal end of the scaphoid combines with the lunate and triquetrum ...
