What is Triscaphe articulation?
What is Triscaphe articulation?
The triscaphe joint is the shared joint between the scaphoid, trapezium and trapezoid bones in the wrist. This joint is also referred to by its much longer name, the scaphotrapeziotrapezoid (STT) joint.
What is Triscaphe degeneration?
Triscaphe degenerative arthritis is the second most common type of degenerative arthritis in the wrist. The most common is the pattern of destruction associated with a scapholunate advanced collapse (SLAC) wrist. The diagnosis is relatively easy when radiographs confirm the isolated joint destruction to the STT joint.
What are the STT joints?
The most common symptom of osteoarthritis of the carpometacarpal (CMC) joint or scapho-trapezium/trapezoid (STT) joint, is pain at the bottom of the thumb. The pain can be worse with activities that require pinching, such as opening jars, turning door knobs or keys, and writing.
What is STT articulation?
Scaphotrapeziotrapezoidal (STT or triscaphe joint) arthritis is common, occurring in ~40% of wrist radiographs. It is typically degenerative (i.e. osteoarthritis) affecting the triscaphe articulation and presents with radial-sided wrist pain in patients over 50 years 1,2. It can be associated with DISI alignment 3.
What does Trapeziectomy mean?
The surgery, called a Trapeziectomy, involves removing a small bone (one of eight which form the wrist) called the trapezium. This is situated at the base of the thumb. This provides more space for the thumb to move so that the arthritic bone surfaces are not rubbing together causing pain.
Is scaphoid hand or wrist?
The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. The bone is important for both motion and stability in the wrist joint. The word “scaphoid” comes from the Greek term for “boat.” The scaphoid bone resembles a boat with its relatively long, curved shape.
How painful is a Trapeziectomy?
Many patients experience a high degree of pain after a trapeziectomy however some appear to have a comfortable and uncomplicated recovery. Research has looked at different surgical and splinting techniques to improve recovery but have found little difference.
What can go wrong with a Trapeziectomy?
Possible complications of a trapeziectomy Possible problems include swelling, bruising, bleeding, blood collecting under the wound (haematoma), infection and splitting open of the wound (dehiscence).
Can you still move your wrist with a scaphoid fracture?
A scaphoid fracture that is correctly treated soon after the injury will take about 12 weeks to heel. But an untreated fracture may take as long as six months to recover from. Untreated patients will also usually experience long-term problems moving their wrist or other complications (see below).
What does scaphoid feel like?
Symptoms of a scaphoid fracture typically include pain and tenderness in the area just below the base of the thumb. These symptoms may worsen when you try to pinch or grasp something. Treatment for a scaphoid fracture can range from casting to surgery, depending on the fracture’s severity and location on the bone.
How to tell if you have triscaphe degenerative arthritis?
Figure 70–1 Localized degenerative arthritis to the scaphoid-trapezium-trapezoid (STT)/triscaphe joint is noted with sclerosis and complete loss of cartilage space. Degenerative arthritis of the thumb carpometacarpal joint is differentiated by tenderness, crepitation, and radiographically confirmed destruction specific to this joint.
How are radial styloids excised in triscaphe degenerative arthritis?
Although not done in this case, we now routinely excise the distal 5 mm of the radial styloid with a rongeur, sloping volarly from distal to proximal. A transverse incision is made in the capsule, and the radioscaphoid joint is inspected. If the radioscaphoid joint has significant degenerative arthritis, then a SLAC reconstruction is performed.
What kind of joint is the triscaphe joint?
This joint is also referred to by its much longer name, the scaphotrapeziotrapezoid (STT) joint. This joint may be fused as an alternative to scapholunate fusion in treatment for certain wrist instability syndromes, or as a treatment for Kienböck disease .
Can a triscaphe joint be fused for Kienbock disease?
This joint may be fused as an alternative to scapholunate fusion in treatment for certain wrist instability syndromes, or as a treatment for Kienböck disease . This procedure is called triscaphe arthrodesis 1 . The triscaphe joint is also a commonly affected site in degenerative and inflammatory arthritis 2 .
