The triangular fibrocartilage complex plays a key role on wrist biomechanics. An accurate injuries diagnosis is paramount for a successful treatment. There are controversies regarding specificity and sensitiveness of imaging methods employed today. Wrist arthroscopy is a method uncommonly used for diagnosing TFCC injuries in our environment, although it presents good advantages, such as the potential of direct viewing injuries, and treatment at the same surgical time. The objective of this study was to evaluate the role of wrist arthroscopy for inspecting TFCC, as well as for detecting potential injuries, comparing those data to gross dissection. Fifteen wrists of male cadavers (mean age: 56.1 years old) were assessed. Arthroscopy showed the presence of injuries in 33.3% of the assessed wrists. Those findings showed consistency after an anatomical study with broad dissection. We concluded that an absolute correlation existed between arthroscopic test and gross dissection in detecting TFCC injuries.
