– Discussion: – may occur from frx (Galeazzi fracture or Colles frx), from radial head frx (as a part of an Essex Lopresti injury) or as an islated injury; – injury to the TFCC is a necessary part of this injury; – dorsal subluxation: … Read more
– See: Radial Radial Inclination – Discussion: – radial-ulnar translation of hand on forearm is may be used in realigning distal radial fragment on the radial shaft; – w/ ulnar translation, the 1st and 2nd extensor compartment tendons and their associatted retinaculum create a radial soft tissue hinge; … Read more

– Discussion: – mean radial inclination was 24 degrees (range, 19 to 29 degrees); – measured on PA view, & describes relative angle of distal radial articular surface to a line perpendicular to long axis of the radius; – this angle normally measures between 16 and 28 deg, av … Read more
– Discussion: – presents w/ differing degrees of shortening (or absence) of radius, carpal bones, and radial rays (including thumb); – bowing of the ulna may contribut to the deformity; – elbow may have fixed extension contracture or may have deficit of active motion; … Read more
– Discussion: – as with ulnar injuries, a mid subtance tear is rare; – Treatment Acute Tears: – if there is no instability and no sign of volar subluxation, the thumb is immobilized for 3 to 4 weeks; – Surgical Treatment: – after curved incision and mobilization of skin flaps, … Read more
