Specifically, the characteristic pattern of arthritic deformity and progressive instability occurs secondary to a long-term, chronic dissociation between the lunate and the scaphoid carpal bones. SLAC wrist is often the terminal and end-stage result from an untreated scapholunate interosseous ligament (SLIL) injury. [1] [2] [3]
Summary Scaphoid Nonunion Advanced Collapse (SNAC) describes the specific pattern of progressive arthritis of the wrist that results from a chronic scaphoid nonunion. Diagnosis is made clinically with progressive wrist pain and wrist instability with radiographs showing scaphoid fracture nonunion with advanced arthritis of the radioscaphoid joint.

Stage III SLAC wrist. PA radiograph shows sclerosis and joint space narrowing between the lunate and capitate, and the capitate will eventually migrate proximally into the space created by the scapholunate dissociation.
Scaphoid non-union advanced collapse (SNAC) is a complication that can occur with scaphoid fractures, specifically non-union of scaphoid fractures. It is essentially the same sequela of wrist injury causing scapholunate dissociation as seen in scapholunate advanced collapse (SLAC).
The scapholunate joint is a small joint between two carpal bones at the wrist crease, namely the scaphoid and lunate bones. The scapholunate joint is very important for the stability of the wrist joint. It is often injured during sport, for example, if you fall heavily onto your hand.

53: Pain in wrist.
Asymptomatic (SLAC) wrist generally does not require treatment. Symptomatic mild SLAC is managed nonoperatively, for example, wrist immobilization with splints, nonsteroidal anti-inflammatory drugs, and corticosteroid injections.
CAUSES. Most cases of SLAC wrist start with a significant wrist sprain or fracture, but occasionally no history of injury is recalled. Some cases of scapholunate ligament injury may be due to repetitive heavy loading of the wrist as seen with obesity, or inflammatory conditions of the wrist that damage the ligament.
What are the treatment options for SLAC wrist? Treatment options are aided at reducing pain. Using a wrist brace during activity can reduce pain. Taking oral anti-inflammatory medications such as ibuprofen and Naproxen can reduce inflammation and pain, and oral Tylenol can reduce pain.
The most common cause of SLAC is rotary subluxation of the scaphoid, which can be attributed to the elliptical configuration of the radioscaphoid joint.

A wrist defect often requiring surgical intervention is scapholunate advanced collapse (SLAC.) SLAC is a condition of progressive instability that causes advanced radiocarpal and midcarpal osteoarthritis. SLAC describes a specific pattern of progressive subluxation with loss of articulation between the scaphoid and lunate bones. SLAC usually results from trauma to the wrist, but may be caused by a degenerative process such as calcinosis or as a sequela of a prior injury. SLAC is estimated to account for more than half of all non-traumatic wrist osteoarthritis cases.#N#Signs and symptoms of SLAC include:
The wrist, or carpus, contains eight carpal bones. There are three bones in the proximal row (scaphoid, lunate, and triquetrum) and five bones in the distal row (trapezium, trapezoid, capitate, hamate, and pisiform). The trapezium is also known as the greater multangular, the trapezoid as the lesser multangular, and the scaphoid as the navicular bone.#N#In ICD-10-CM, most wrist conditions coded from chapter 13 (M codes) have a “3” in the fifth position of the code such as M19.031 Primary osteoarthritis, right wrist. Common conditions of the wrist and distal radius from chapters 13 and 19 (M and S codes) are:
Coding fracture of carpal bone (S62.1- Fracture of other and unspecified carpal bone (s)) when the diagnosis is a distal radius fracture (S52.5- Fracture of lower end of radius ).
De Quervain’s disease (radial styloid tenosynovitis) is an inflammation of the first dorsal extensor compartment; this is entrapment tendinitis causing tendon thickening, which leads to restricted motion and a grinding sensation with tendon movement (crepitus).
Hand weakness or stiffness, especially with regard to grip strength.
The wrist is classified as an “intermediate” joint, but consists of many intricate structures and bones. Accurate coding of wrist diagnoses, services, and procedures requires a solid working knowledge of wrist, hand, and distal forearm anatomy.
The operations needed to treat this process are typically complex procedures that will require hand therapy post-operatively. Managing patient expectations is also critical. Four-corner arthrodesis is a complex procedure that can have long-term implications on a patient's occupational functionality. An informed decision with knowledge of outcomes should be discussed with the patient to establish whether surgery is advisable, especially in those with significant comorbidities. Alternative treatments should also be discussed. A preassessment that includes blood tests, an electrocardiogram, and further imaging to guide surgical course can be obtained. An anesthetic review by an anesthesiologist or certified nurse anesthetist should also be performed in patients with comorbidities, as well as guiding pain relief as appropriate. A physical therapy assessment during the course of recovery is also an important step in the immediate and long-term post-operative course. Follow-up clinic visits also play a role in expediting the correction of postoperative complications.
As the normal opposing forces at the SL interval are lost, the scaphoid assumes an abnormally flexed position , while the lunate pathologically deviates into extension. [13]This condition results in a dorsal intercalated segment instability (DISI deformity) pattern. The scapholunate angle increases to greater than 70 degrees while the lunate is extended to greater than 10 degrees beyond neutral. These abnormal flexion and extension positions alter the distribution of forces across the midcarpal and radiocarpal joints. Eventually, cartilage degeneration occurs beginning with the radioscaphoid joint (recognized on radiographs at the radial styloid).
A scapholunate ballottement test can also be performed. [19]The lunate is firmly stabilized with the thumb and index finger of one hand, while the scaphoid, held with the other hand is displaced dorsally and palmarly with the other hand. A positive result elicits pain, crepitus, and excessive mobility of the scaphoid.
Scapholunate advanced collapse (SLAC) is a characteristic degenerative clinical wrist condition of progressive deformity, instability, and arthritis that affects the radiocarpal and mid-carpal joints of the wrist. Characteristically, the arthritic deformity and progressive instability occur due to a long-term, chronic dissociation between the scaphoid carpal bones and the lunate bone. This condition is the result of an untreated scapholunate interosseous ligament (SLIL) injury. Patients will have a history of trauma, and some degree of pain made worse by heavy use. The mild disease needs only non-operative treatment such as NSAIDs, wrist splints, and corticosteroid injections with operative management indicated for more complicated cases. This activity illustrates the evaluation and management of scapholunate advanced collapse and explains the role of the interprofessional team in improving care for patients with this condition.
To perform the (Watson) scaphoid shift test, firm pressure is applied to the palmar tuberosity of the scaphoid while the wrist is moved from ulnar to radial deviation. In normal wrists, the scaphoid cannot flex because of the external pressure by the examiner's thumb. A positive test is seen in a patient with a scapholunate tear or a patient with a lax wrist. When pressure on the scaphoid is removed, the scaphoid goes back into position, and a typical snapping occurs.
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] Specifically, the characteristic pattern of arthritic deformity and progressive instability occurs secondary to a long-term, chronic dissociation between the lunate and the scaphoid carpal bones. [2] SLAC wrist is often the terminal and end-stage result of an untreated scapholunate interosseous ligament (SLIL) injury. Radiographic, CT, and MRI imaging often demonstrate widening of the scapholunate interval, degenerative changes of the affected carpal bones, and proximal migration of the capitate. [3] A four-stage categorization to grade arthrosis is often used. [4] Treatment most commonly includes four-corner arthrodesis, capitolunate arthrodesis, and scaphoidectomy. [5]
The pathologic cascade continues in an ulnar-based direction, with the final iteration yielding the collapse of the capitate proximally between a widened SL interval (known as the "Terry Thomas sign"), and end-stage patterns include capitolunate arthritis. [14]Of note, the radiolunate joint remains spared in the SLAC pattern of degenerative deformity.
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 . It is essentially the same sequela of wrist injury causing scaphoid nonunion as seen in scaphoid nonunion advanced collapse (SNAC).
SLAC is most commonly a consequence of undiagnosed or untreated scapholunate ligament injury and rotatory subluxation of the scaphoid bone resulting in radioscaphoid malalignment, progressive chondromalacia, and osteoarthritis.
In later stages of the disease, osteoarthritis affects the whole radioscaphoid articulation, then the articulation between lunate and capitate. Finally, it may involve other intercarpal joints. In addition, there is scapholunate interval widening as well as proximal migration of the scaphoid and the capitate 3.
