Aug 12, 2024 · What is a scapholunate ligament tear in athletes? A scapholunate ligament tear can vary from mild sprains (partial tears or “stretches”) all the way to complete tears with other torn ligaments. They may also be accompanied by other injuries such as a scaphoid fracture or a lunate dislocation.

When a ligament is injured, this is referred to as a sprain. A very common ligament injured in a sprained wrist is the scapholunate ligament. This ligament is in the middle of the wrist between the scaphoid and lunate bones (Figure 1). It is an important structure for …

Mar 9, 2025 · Scapholunate Ligament Injury is a source of dorsoradial wrist pain with chronic injuries leading to a form of wrist instability (DISI deformity). Diagnosis is made with PA wrist radiographs showing widening of the SL joint. Diagnosis of DISI deformity can be made with lateral wrist radiographs showing a scapholunate angle > 70 degrees.

May 30, 2021 · So, how do we diagnose a chronic scapholunate ligament tear, also known as SL ligament tear, and what do we do about it? What is the scapholunate ligament? The large and complex scapholunate ligament connects two essential bones in the wrist – …

A scapholunate tear is the first stage of Mayfield’s four stage perilunate classification. Mayfield’s four stages are: Stage I - tear of the scapholunate ligament; Stage II – disruption of the lunocapitate joint through the Space of Poirier; Stage III - lunotriquetral joint dissociation; and Stage IV - lunate dislocation. 12

In symptomatic static irreducible SLD, the most commonly advocated treatment is partial fusion. SL fusion is probably the least reliable option, with small areas of bone contact and a high separating force in the SL interval by the capitate. Nonunion has been reported in approximately 50% using this method.

SL ligament injury can result in abnormal gapping between the scaphoid and lunate bones. This is known as “scapholunate dissociation.” The bones also rotate abnormally after SL ligament tears, with the scaphoid rotating forward, and the lunate rotating backwards.

Scapholunate ligament (SLL) injuries are a common cause of wrist pain and instability. Treatment of SLL injuries requires intricate understanding of wrist anatomy and biomechanics. Mindful physical exam and appropriate diagnostic studies can orient the …

What is a Scapholunate Ligament Tear? Details of the causes, symptoms and available Scapholunate Ligament Tear treatment options.

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.
