The role of arthroscopy in the treatment of scapholunate dissociation
This article describes a technique of treating acute and subacute scapholunate dissociations using arthroscopic techniques. The physical findings and radiographic abnormalities associated with scapholunate disruption, as well as the portal anatomy in wrist arthroscopy, are discussed. The technique of arthroscopic debridement of the torn ligament to create a suitable environment in a fibrous pseudoarthrosis is explored, as are the technique of arthroscopic-assisted visualization of the reduction from the radiocarpal and midcarpal joints and the use of the image intensifier in percutaneous pin fixation of that reduction. Finally, this article details the postoperative regimen used by the senior author (GGP). The authors believe that the technique of arthroscopic-assisted scapholunate ligament reconstruction provides a relatively noninvasive option with low morbidity for the management of a difficult problem. Further, it permits the diagnosis and possible treatment of associated ligamentous and cartilaginous injuries. © 1992 Aspen Publishers, Inc.
