Abstract:

One or more small plates is provided for the fixation of the scapholunate interval between scaphoid and lunate. In one embodiment, a plate is fixed to the bones with fixed angle fasteners to allow complete healing and remodeling of the scapholunate ligament. In another embodiment, the system includes two small plates for the scaphoid and lunate joined by a central element. In yet another embodiment, the system includes two bone anchors for the lunate and scaphoid, also joined by a central element. The central element is flexible, and/or the plates or anchors are movably joined to the central element. The central element in each of these embodiments acts like an artificial ligament and permits more normal motion of the wrist bones while maintaining the scapholunate interval at its correct anatomical dimension.
