There are three different patterns of arthropathy seen about the wrist which include SLAC, triscaphe arthritis (between the trapezium, trapezoid and distal scaphoid) and a combination pattern. SLAC wrist is the most common type of wrist arthritis and accounts for approximately 55 % of all wrist arthritis [14].
Also, What is the treatment for SLAC wrist?
Scaphoid excision and four-corner arthrodesis reliably diminished wrist pain in patients with stage III SLAC wrist while maintaining a 54 degrees flexion-extension arc. Stage II SLAC wrist can be successfully treated with this procedure, radioscaphoid arthrodesis, or proximal row carpectomy.
Considering this, What is the little bone in your wrist called?
Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna.
What is wrist fusion?
Total wrist arthrodesis, also known as wrist fusion is a surgical procedure in which the wrist joint is stabilized or immobilized by fusing the forearm bone (radius) with the small bones of the wrist. Arthrodesis is done to relieve the pain after severe trauma to the wrist.
Hereof, What is advanced collapse wrist? Scapholunate advanced collapse (SLAC), commonly known as SLAC wrist, refers to a pattern of wrist malalignment that has been attributed to post-traumatic or spontaneous osteoarthritis of the wrist. It is a complication that can occur with undiagnosed or untreated scapholunate dissociation.

How long does a proximal row Carpectomy last?
Overall, proximal row carpectomy remains a technically simple procedure and is capable of preserving motion and grip strength beyond 20 years; however, patients should be instructed that failure rates can be as high as 15%, pain relief may deteriorate over time, and patients may require daily medication to help resolve …
What is scapholunate?
The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate.
What happens if a scaphoid fracture is left untreated?
A scaphoid fracture can lead to wrist osteoarthritis, especially if the fracture is untreated and does not heal correctly. This is called “nonunion.” Severe cases of this kind of osteoarthritis can lead to an incorrect alignment of wrist bones in what is called scaphoid nonunion advanced collapse (SNAC).
Can I break my wrist without knowing?
Sometimes a bone can break without you realizing it. That’s usually what happens to the scaphoid bone in your wrist, a boat-shaped bone located on the outermost side of the thumb side of the hand.
What body part has the most bones?
The hands and feet contain over half of the body’s bones.
Coming out on top are your hands and feet. Each hand has 27 bones, and each foot has 26, which means that together the body’s two hands and two feet have 106 bones.
Do they put you to sleep for wrist surgery?
In most hospitals, surgery on the hand and wrist is usually performed using regional anesthesia and intravenous sedation, or general anesthesia. Patients must undergo preoperative tests, fast starting the night before, and spend an hour or more in a recovery room.
Is wrist fusion painful?
While you will lose some range of motion after wrist fusion surgery, you will no longer have pain, and you will regain the lost strength in your wrist over time. You will once again be able to grip and have strong flexion in your hand. If strength is essential for your line of work, wrist fusion is an excellent option.
Is wrist fusion a disability?
Long-term follow-up studies have demonstrated that fused wrists can be tender, the functional disability troublesome, and the majority of patients miss a minimum of movement. 1 There is a direct correlation between decreased wrist motion and functional disability.
What is a scaphoid fracture?
A scaphoid (navicular) fracture is a break in one of the small bones of the wrist. This type of fracture occurs most often after a fall onto an outstretched hand. Symptoms of a scaphoid fracture typically include pain and tenderness in the area just below the base of the thumb.
What is Kienbock disease?
Kienböck’s disease is a condition where the blood supply to one of the small bones in the wrist, the lunate, is interrupted. Bone is living tissue that requires a regular supply of blood for nourishment. If the blood supply to a bone stops, the bone can die. This is called osteonecrosis.
Why do a proximal row Carpectomy?
In cases of severe arthritis of the wrist, surgical removal of the scaphoid, lunate and triquetrum bones or proximal row carpectomy (PRC) is a well-known procedure. This procedure converts the wrist in a simple hinged joint but allows us to preserve a certain range of motion in the wrist.
What is a Trapeziectomy?
What is a trapeziectomy? A trapeziectomy involves removing the trapezium, a small bone in your wrist. Your arm may be numbed using a regional anaesthetic or a general anaesthetic may be used. Your surgeon will make a small cut on the back of your hand at the base of your thumb, and remove your trapezium.
What happens after proximal row Carpectomy?
Finger movements are encouraged straight after surgery whereas wrist motion exercises are started 5-7 days after the operation. If there is a wrist swelling, an elastic garment can be applied for edema control. By six weeks, no immobilization is necessary and an aggressive strengthening program can be initiated.
How do you test for scapholunate?
The patient’s hand is slightly pronated and the examiner places his thumb on the palmar side of the scaphoid (on the scaphoid tubercule), his other fingers are wrapped around the back of the wrist at the distal part of the radius. This will allow the examiner to put pressure on the scaphoid with his thumb.
What does a scapholunate tear feel like?
Common Causes of Scapholunate Ligament Tear
Often, the wrist injury may just “feel like a sprain” and the pain and swelling may subside over several weeks. However, if the SL Ligament was torn, pain with certain wrist positions and a feeling of weakness/instability can persist.
What is a scapholunate dissociation?
Scapholunate dissociation is the abnormal orientation or movement of the small bones of your wrist: the scaphoid and lunate, in relation to one another.
Is a scaphoid fracture serious?
Scaphoid fractures that are not diagnosed and treated are in danger of developing two serious complications: Nonunion—when the bone fragments heal improperly or incompletely. Avascular necrosis—when the fracture causes blood supply to be cut off to part or all of the bone, causing the bone tissue to die.
How long do you wear a cast for a scaphoid fracture?
Whether your treatment is surgical or nonsurgical, you may be required to wear a cast or splint for up to 6 months or until your fracture has healed. Unlike most other fractures, scaphoid fractures tend to heal slowly.
Can you move your thumb with a scaphoid fracture?
A scaphoid fracture causes tenderness directly over the bone and the pain may increase when you move your thumb or grip things. Your initial pain may decrease over days or weeks and because there is no significant bruising or swelling they are often mistaken for a sprained wrist.
