We retrospectively reviewed 13 patients who had successfully undergone three-ligament tenodesis for scapholunate instability, and compared the radiological outcome with 14 failed cases. The scapholunate angle in the failed group increased from 73 degrees to 81 degrees with a scapholunate gap of 532 mm, compared to a decrease in the successful group from 76 degrees to 66 degrees with a scapholun...

This paper is a review of the various surgical techniques used in repair or reconstruction of the scapholunate ligament according to the clinical stages and anatomic-pathologic findings. Arthroscopy permits a direct evaluation of the scapholunate injury and the status of the articular surfaces. Specific indications for each type of scapholunate ligament tear are proposed, from the different typ...

Injuries to the scapholunate joint [SLJ] are the most frequent cause of carpal instability and account for a considerable degree of wrist dysfunction. It is insufficient to cause abnormal carpal posture or collapse on static radiographs, an isolated injury to the scapholunate interosseous ligament may cause progression to abnormal joint mechanics, cartilage wear, and degenerative changes. Inter...

Scapholunate instability is the most common carpal instability. The evaluation and treatment of scapholunate instability is controversial and the outcome unpredictable. This article will review the pertinent ligamentous anatomy of the wrist and carpal kinematics. There will be a discussion of the clinical presentation, examination, and diagnostic testing of the patient suspected of having scaph...

Posttraumatic instability of the wrist, resulting in scapholunate dissociation, is a common injury pattern in the wrist [2]. Mayfield et al. [1] described instability progressing sequentially from a scapholunate interosseous ligament (SLIL) tear to complete ligament failure around the lunate, resulting in lunate dislocation. Linscheid et al. [4] also demonstrated that excision of the dorsal rad...

A consecutive series of 100 cases of wrist injury, other than those referred with a radial fracture, have been reviewed to determine the incidence of acute scapholunate instability; a "clenched fist" radiograph was used in addition to the routine scaphoid views. Of 19 patients with an increase in the scapholunate gap, five were eventually considered to have significant scapholunate instability,...

Thirty-five of the 49 patients also underwent fluoroscopy-guided 3T MR arthrography of the wrist joint using a gadolinium/saline contrast mix. Arthroscopy found TFCC tears in 22 patients, scapholunate tears in 18, and lunatotriquetral tears in 11. Nineteen TFCC tears, 16 scapholunate tears, and nine lunatotriquetral tears were seen on 3T MRI. There were no false-positive readings on MRI compare...

The natural history of an untreated isolated scapholunate interosseus ligament injury remains unclear, although it is commonly assumed that patients continue to suffer with pain, stiffness and weakness of the wrist and ultimately develop secondary osteoarthritis (SLAC wrist). In this study, we evaluated the clinical condition of 11 patients with an arthroscopically proven interosseus scapholuna...

Introduction: Scapholunate ligament injury is rare in children. Most of the cases occur with concomitant distal radius fractures. Complete scapholunate disruption may present with long term pain and disability. Case Report: We present a case of scapholunate injury in a youngest patient reported in literature with this injury. The senior author managed the injury with a modified extra-osseous re...

The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a cont...
