– See: RU joint – Discussion:     – refers to impingement of the ulnar head against the carpi which can lead to TFCC tears and lunotriquetral ligament attrition;     – lunotriquetral ligament attrition may occur from compression and translation shear as the lunate becomes impinged against the ulnar head;     – causes:   … Read more

Ulnocarpal Impingement Syndrome

– Discussion:     – impingement of distal ulna on carpi which may arise from positive ulnar variance or non union of distal ulnar frx;     – positive ulnar varience leads to loading of the ulnocarpal joint and resultant LT disruption, lunate chondral lesion, and TFCC tears;     – diff dx: (ulnar sided … Read more
