Scapholunate Instability: Current Concepts in Diagnosis and Management

Influence of associated lesions of the intrinsic ligaments on distal radius fractures outcome

“…According the literature recommendations, treatment is indicated for traumatic grades III and IV lesions of the scapholunate and lunotriquetral ligament [3,17]. In the present study, seven patients (17.5 %) presented with associated grades III or IV SL injury and six (15 %) presented with LT injury.…”

“…Most experts now agree on immediate surgical intervention if such severe disruptions are noted acutely following distal radius fractures. In such instances, even a direct open repair of the scapholunate ligament could be considered and the repair protected with K-wires [3,8,17]. Concomitant dorsal capsulodesis has shown to be useful in reinforcing the repair [3].…”

Length changes of scapholunate interosseous ligament at different wrist positions: an in vivo 3-dimension image study

“…Our data showed the mean percent elongation in full extension to be 43.8, 36.8, 29.5 %, respectively, for the distal, middle, proximal portion of volar SLIL, and 21.2, (Table 3). Previous investigators have emphasized the importance of the dorsal SLIL for maintaining stability between the scaphoid and lunate [2,10,22]. The dorsal region is the strongest component of the SL ligament complex.…”

Accuracy of simple plain radiographic signs and measures to diagnose acute scapholunate ligament injuries of the wrist

“…They typically result from forced hypertension or fractures of the wrist and, if missed and untreated, expose patients to a high risk of posttraumatic osteoarthritis of the radio-carpal joint. The reported prevalence of SL ligament tears among studies which used wrist arthroscopy as a diagnostic reference standard after trauma ranges from 9 to 32 % [1,2].…”
