The TFCC injuries are usually diagnosed by a coronal MRI. We have described the Float image for the diagnosis of peripheral injuries of the TFCC. In a sagital image parallel to the ulnar diaphysis and placed lateral to the ulnar fovea, we can observe the radiocubital dorsal and volar ligaments of the TFCC. A distance of more than 4mm between the dorsal edge of the meniscus and the joint capsule suggests the presence of TFCC peripheral rupture. 51 pacients were selected from all the patients who underwent wrist arthroscopy between 2006–2009. Inclusion criteria: MRI at our hospital, arthroscopy at our hospital, no presence of radial fracture. We assessed the correlation between the presence of the Float image and a TFCC injury confirmed by arthroscopy.INTRODUCTION
