Wrist arthroscopy has been established as a useful, minimally invasive tool for diagnosing and treating many different wrist conditions. The standard portals are located on the dorsum of the hand and wrist and are named for their relation to the extensor compartments. They include the radiocarpal and midcarpal portals. The radiocarpal portals are 3-4, 4-5, 6R, 6U, and 1-2. The midcarpal portals are STT (scaphotrapeziotrapezoidal), MCR (midcarpal radial), and MCU (midcarpal ulnar). Traditionally, wrist arthroscopy is performed with constant inflow of saline solution for joint insufflation and visualization. Dry wrist arthroscopy (DWA) is a technique that allows for arthroscopic exploration and instrumentation without infusing any fluid into the joints. Some advantages of DWA include lack of fluid extravasation, less obstruction by floating synovial villi, decreased risk of compartment syndrome, and the ability to perform concomitant open procedures more easily than with a wet technique. Additionally, the risk of fluid displacing carefully laid bone graft is much less without constant flow. DWA can be used in the assessment and management of triangular fibrocartilage complex (TFCC) and scapholunate interosseous ligament tears and other ligamentous injuries. DWA can also be used in fracture fixation to assist with reduction and restoration of articular surfaces. Moreover, it is used in more chronic settings to diagnose scaphoid nonunions. DWA does have its disadvantages such as generation of heat through the use of burrs and shavers and clogging of these instruments during debridement of tissue. DWA is a technique that can be used to manage multiple orthopaedic conditions including soft-tissue and osseous injuries. With a minimal learning curve for surgeons who already perform wrist arthroscopy, DWA can be a useful addition to their practice. Copyright © 2023 Arthroscopy Association of North America.
