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 ]
Wrist osteoarthritis is gradual loss of articular cartilage and hypertrophic bone changes (osteophytes). While in many joints this is part of normal aging (senescence), in the wrist osteoarthritis usually occurs over years to decades after scapholunate interosseous ligament rupture or an unhealed fracture of the scaphoid.
Differential diagnosis: 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)
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 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 ...
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.
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.
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.
