Sanj Kakar, a renowned hand surgeon from the Mayo Clinic, shares groundbreaking insights on wrist arthroscopy. He explores the innovative technique of dry arthroscopy, discussing its efficiency and the challenges of diagnosing TFCC tears. Kakar also highlights the revolutionary DREJ arthroscopy and nanoscope technology, emphasizing their roles in minimally invasive treatments. The conversation delves into scapholunate ligament injuries and the evolving approaches to wrist surgery, making complex techniques accessible for both practitioners and enthusiasts.
Dry arthroscopy enhances surgical efficiency and visibility while reducing complications, particularly in treating distal radius fractures.
Thorough evaluation techniques for the Triangular Fibrocartilage Complex (TFCC) are crucial for accurate wrist injury diagnoses and management.

The Shift to Dry Arthroscopy
Dry arthroscopy allows for greater efficiency in procedures compared to the traditional wet method. Surgeons can manipulate larger instruments and achieve better visualization since the absence of fluid reduces obscurity caused by soft tissue swelling. Many surgeons have transitioned from wet to dry methods after witnessing the benefits in practice, such as diminished risks of complications like compartment syndrome. Specifically, dry arthroscopy has been particularly useful in treating conditions like distal radius fractures, where fluid presence can hamper visibility and control.
Patient Evaluation Techniques for TFCC Injuries
A thorough evaluation of the Triangular Fibrocartilage Complex (TFCC) is essential in diagnosing wrist issues. Surgeons commonly use techniques such as the trampoline, hook, and suction tests to identify the presence of tears, as well as scoping the distal radioulnar joint (DRUJ) for a complete assessment. Notably, the hook test has been highlighted as a reliable method for eliciting sensitivity in foveal tears, ensuring comprehensive examination of potential injuries. Following these evaluations can lead to more accurate diagnoses, including distinguishing between peripheral and foveal injuries.
Advancements in SL Tear Management
The approach to scapholunate (SL) ligament injuries has evolved significantly, emphasizing the importance of tailored treatment plans based on individual patient assessments. Arthroscopy facilitates direct visualization and intervention, allowing surgeons to address both the volar and dorsal SL injuries effectively. Studies indicate that many SL tears are overlooked due to normal x-ray results; hence, surgeons are encouraged to assess for high-grade instability even when imaging appears clear. Furthermore, procedures should focus not solely on reconstruction but also on managing associated injuries, including those to the long radiolunate ligament.
Utilizing Nanoscopes for Hand Surgery
Nanoscope technology has propelled advancements in minimally invasive hand surgeries, enabling surgeons to access smaller joints with less trauma. The flexibility of nanoscopes allows for effective diagnosis and treatment across various conditions, including TFCC tears and small joint injuries. Their use proves particularly beneficial for arthroscopic procedures in challenging areas like the MCP joint, which previously posed difficulties. As surgeons gain experience with this technology, it has the potential to enhance dexterity and precision in managing conditions that require intricate surgical intervention.
