About this Research Topic
The scapholunate interosseous ligament plays a crucial role in stabilizing the carpus during wrist motion. Disruption of the scapholunate ligament complex invariably leads to carpal instability and over time, predictable alterations in the kinematics of carpal motion occur, ultimately resulting in progressive degenerative arthritis otherwise known as scapholunate advanced collapse (SLAC). Given that the scapholunate ligament is the most commonly injured ligament in the wrist, early detection and understanding of the treatment options is imperative, as one can intervene appropriately to alter the natural history of this condition. In recent times, there have been significant advances in the overall understanding of the anatomical changes that occur with scapholunate instability and how this alters wrist biomechanics. In addition, advances in technology with imaging modalities such as 4D CT scans have also been significant, and this has provided another tool which allow assessment of both normal and abnormal carpal motion, which has important implications, especially with respect to determining our goals of reconstruction. As such, various treatment options, both non-operatively and operatively, have been proposed based on this increased understanding. In this Research Topic, we will discuss all aspects of the scapholunate interosseous ligament and present the current literature pertaining to anatomy, biomechanics and radiological analysis. Furthermore, we will present current and emerging treatment options and a propose a paradigm for management of the whole spectrum of scapholunate ligament injuries and its sequelae.
