Surgical arthroscopy of the wrist is a minimally invasive procedure that involves the use of an arthroscope to visualize and treat conditions within the wrist joint. Specifically, this procedure is performed to address infections by allowing for lavage, which is the flushing of the joint with sterile solutions, and drainage, which involves the removal of infected fluid or pus. The patient undergoing this procedure is typically positioned supine, meaning they lie on their back, with the shoulder abducted to facilitate access to the wrist. A pneumatic tourniquet is applied to the upper arm to minimize blood flow to the area, enhancing visibility and control during the procedure. To further aid in visualization, the forearm is suspended in a wrist traction device, and weights are applied to the second and third fingers, creating distraction in the wrist joint. This distraction allows the surgeon to better see the joint structures and perform the necessary interventions. The procedure involves making small incisions, or portals, in the skin over the wrist to introduce the arthroscope and other surgical instruments. Through these portals, the surgeon can effectively drain the infected material and flush the joint with sterile saline or an antibiotic solution, ensuring thorough cleaning of the infected area. Additional incisions may be made as needed to access other parts of the wrist joint, such as the midcarpal joint, to ensure complete drainage and lavage. After the procedure is completed, the instruments are removed, and the incisions are closed, allowing for a quicker recovery compared to traditional open surgery.
