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 ]
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.
The management and treatment of SLAC wrist depends on the stage at the time of diagnosis. The options for management can be separated into two broad categories: non-surgical and surgical. Less advanced SLAC wrist may be managed initially with non-surgical options including nonsteroidal anti-inflammatory drugs , wrist splinting , and steroid ...
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.
Scaphoid pseudarthrosis, before and after treatment with Herbert screw. The Herbert screw (invented by Timothy Herbert) is a variable pitch cannulated screw typically made from titanium for its biocompatible properties as the screw is normally intended to remain in the patient indefinitely. It became generally available in 1978.
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...
