Results
One hundred forty-four cases were diagnosed TFCC injury. In this study, Palmer 1B (n=113), UC (n=98) and 1A (n=85) were more common injuries (Table 1). Most of TFCC injuries were more than one component lesions (81% > 1, average 3.2). Majority of those were 4 component injuries (n=32) followed by 1 component (n=27) and 2 components (n=24) injuries (Fig. 5). ECU tendon/sheath injuries (n=83) were related to 1B (n=76) and UC (n=73) injuries, and frequently associated with DRUL more than VRUL (46 vs 13) injuries (Fig. 1 , Fig. 2 and Fig. 4). 1D lesions (n=9) were rare and had strong relationship with an adjacent 1A lesion (Fig. 3). 1C lesions were often associated with higher number of components (Average 5.2, maximum up to 7) involvement (Fig. 2 and Fig. 4). Meniscus homologue injury was a rare occurrence (n=7) and was also related to the higher number (Average 5.4) of TFCC components involvement (Fig. 4).
