Scapholunate instability remains an unsolved indication in orthopaedics. The Acumed SLIC Screw System is an adjunct to the biological healing of soft tissue repair or reconstructions that treat scapholunate instability. The system includes system-specific instrumentation, a specialized targeting guide, and multiple-size screws to accommodate varying patient anatomy. The Acumed SLIC Screw can be used to hold the reduction of the scapholunate interval while the soft tissue repair heals. The jointed screw allows relative rotation and an anatomic toggle of 15-22 degrees, allowing the scaphoid and lunate to move anatomically while the soft tissue heals.
The patented, cannulated cylinder-in-cylinder design allows the joint of the screw to sit at the SL interval in order to allow maximum relative rotation between the bones. The scaphoid portion of the screw varies in length while the lunate portion is consistent across all three screws. This allows the back end of the screw to sit just below the articular cartilage of the radial side of the scaphoid to aid in screw removal.
The SLIC Screw System provides instrumentation specific to each screw size:
