Ulnar Styloid Process Frx

– Anatomy:      – Tunnel V:           – overlies distal ends of radioulnar articulation on dorsum of wrist, contains EDM;     – Tunnel VI:           – in groove between the apex of ulnar styloid process & ulnar head, contains ECU tendon which is palpable from … Read more

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

Ulnar Bursae

– Anatomy:     – ulnar bursae includes little finger tendon sheath which begins at terminal phalanx & extends proximally half way up the palm;           – occassionally the distal unexpanded part of little finger tendon sheath does not communicate w/ ulnar bursae;     – in the palm, the ulnar … Read more

Ulnar drift: of MP joints

– See:      – MP joint deformities      – Distal Ulna Arthroplasty      – Rheumatoid Hand – Anatomical Contributing Factors: (to ulnar drift)     – normal mechanical advantage of the ulnar intrinsic muscles     – asymmetry & ulnar slope of MC heads of index & middle fingers;     – asymmetry of the collateral … Read more
