Ulnar Translocation

– Discussion:     – most frequent radiocarpal instability;     – the lunate is translocated ulnarly, and therefore is not supported by the radius;     – ulnar translationn is also commonly seen in disease such as RA or in Madelung’s deformity;             – in RA, may occur along … Read more

Ulnar Variance

– Discussion:     – mean ulnar variance is 0.9 mm (range: 4.2 to 2.3 mm);     – functional anatomy:            – w/ neutral variance, 80% of load is born by radius and 20% by ulna;            – 2.5 mm increase in ulnar varience will increase … Read more

Ulna / Ulnar Shaft Fracture

(see also: Both Bone Forearm Fracture: / Ulnar Styloid Process) Anatomy radius & ulna lie parallel to each other when forearm is supinated; during pronation radius crosses ulna, rotating on axis that passes from capitulum through the distal end of ulna; ular side of wrist is supported by TFCC, which articulates w/ both lunate and triquetrium; … Read more
