Arthroscopic Midcarpal Suture Anchor Repair of Dorsal Intercarpal Ligament Avulsion

Abstract

The dorsal intercarpal ligament (DICL) is crucial for carpal stability and is frequently associated with injuries to other carpal ligaments, notably the scapholunate and lunotriquetral interosseous ligaments. Although isolated DICL injuries are uncommon, they can manifest as ligament avulsions, bony avulsions, or attenuations from chronic injury. Surgical repair of isolated DICL tears may be necessary when conservative management fails. We have previously described the first isolated DICL avulsion from the scaphoid dorsal ridge, suggesting an arthroscopic repair via the radiocarpal joint. This article details a repair technique through the midcarpal joint.
