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] Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone ...
The Brunelli Procedure does not fix the torn ligament. A hole is drilled through the Scaphoid bone and a part of a tendon taken from the patient is put through this hole and attached to the nearby bones. The procedure usually results in reduced movement of the wrist. Instability in the wrist can, over time, lead to wrist osteoarthritis.
Arthroscopy can be used to treat an intra-articular distal radius fracture and at the same time examine the Scapholunate ligament, Lunotriquetral ligament and articular disk. [5] The shifted bone segment is relocated, in necessary a bone autograft can be used to fill up the fracture. At the end the fracture is stabilized using percutane wires.
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.
Four corner fusion, or partial wrist arthrodesis, is a procedure which involves resection/removal of the scaphoid bone and fixation of the remaining wrist bones with a plate or wires. [1] The procedure is usually performed due to wrist arthritis or due to scaphoid collapse.
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 ...
