Modern approaches to the treatment of scapholunate interosseous ligament injuries (literature review)

Shershneva O.G., Kirpichev I.V.


The scapholunate interosseous ligament binds the scaphoid and lunate together, and is the primary stabilising ligament between these two bones. Scapholunate injuries lead to chronic instability and degenerative arthritis of the wrist. Scapholunate injuries are graded based on the acuity and the severity of the injury.
The paper is a review of various techniques used to repair or reconstruct the scapholunate ligament according to the clinical manifestations, anatomic and pathologic findings.
A review of the literature covering this topic is presented.
Conservative treatment is primarily indicated in stable and partial ligament tears. Arthroscopic treatment is used when immobilization is unsuccessful.Arthroscopically assisted scapholunate reduction and K-wire fixation is commonly used for acute injuries. Primary repair of scapholunate injuries are performed in all tear types using an open approach. Surgical indications depend on the severity of the instability, time after trauma and the presence of degenerative changes. Acute repair of scapholunate ligament injuries remains the gold standard as an earlier intervention provides better results. Acute injuries to the scapholunate ligament require two-four weeks before surgery. Within this period the ligament is often still repairable itself both with or without supplementary capsulodesis procedures; ligament reconstruction is generally preferable in patients with chronic injures. There are many arthroscopic techniques to treat chronic scapholunate injures such as scapholunate ligament primary repair using various types of capsulodesis, tendon graft reconstruction, bone-ligament-bone procedure, various intercarpal fusions and proximal row carpectomy, total wrist fusion and arthroplasty.
Early diagnosis and management of scapholunate ligament tears are necessary to preserve wrist functions.
