What does scapholunate advanced collapse mean?

What does scapholunate advanced collapse mean?

Scapholunate advanced collapse (SLAC) describes a characteristic degenerative clinical wrist condition of progressive instability, deformity, and arthritis affecting the radiocarpal and midcarpal joints of the wrist. [

How do you fix scapholunate instability?

3 Main Treatments for a Scapholunate Ligament Injury

1. Immobilization of the Wrist. Immobilization with a wrist orthosis in the acute stages is a common intervention provided by a therapist in the acute stage.
2. Wrist Stabilization. Wrist stabilization involves strengthening the SL “friendly” muscles.
3. Proprioceptive Exercise.

What are the implications for wrist function with untreated Scapho lunate dissociation?

The two primary complications due to scapholunate dissociation are Scapholunate Advanced Collapse (SLAC) and general arthritis of the wrist.

What is a collapsed 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.

Why does my wrist collapse?

If a ligament is torn, it may allow a wrist bone to shift out of place, resulting in improper wear and tear of the cartilage. A ligament between the Scaphoid and the Lunate is at risk in a wrist injury. If it tears and causes arthritis, it is called Scapho-Lunate Advanced Collapse (SLAC) wrist arthritis.

What is a Scapholunate dissociation?

Scapholunate (SL) dissociation is part of a spectrum of traumatic carpal bone instabilities and is defined as disruption of the ligamentous complex holding the scaphoid and lunate together.1 The SL ligament complex consists of the volar, dorsal, and intermediate components, with the dorsal component being the strongest …

What causes Scapholunate widening?

Scapholunate dissociation most commonly results from trauma. It is the leading cause of SLAC (scapholunate advanced collapse) wrist, which is the most common pattern of degenerative arthritis in the wrist 4.

Which is the correct description of scapholunate advanced collapse?

Scapholunate advanced collapse (SLAC) describes a characteristic degenerative clinical wrist condition of progressive instability, deformity, and arthritis affecting the radiocarpal and midcarpal joints of the wrist. [1]

What causes scapholunate advanced collapse ( SLAC ) wrist pattern?

A SLAC wrist pattern is the result of many radial-side wrist pathologies (see the images below). Most common is scapholunate dissociation with rotatory subluxation of the scaphoid.

Is there such a thing as scaphoid nonunion advanced collapse?

It is a complication that can occur with undiagnosed or untreated scapholunate dissociation. It is essentially the same sequela of wrist injury causing scaphoid nonunion as seen in scaphoid nonunion advanced collapse (SNAC).

What kind of arthritis is scaphoid lunate advanced collapse?

Scaphoid Lunate Advanced Collapse (SLAC) describes the specific pattern of degenerative arthritis seen in chronic dissociation between the scaphoid and lunate. Diagnosis is made clinically with progressive wrist pain and wrist instability with radiographs showing advanced arthritis of the radiocarpal and midcarpal joints (radiolunate joint spared).
