– Discussion:     – comprises articular frx w/ articular incongruity but minimal comminution;     – frx extend into the joint distally from a spiral frx of distal tibia     – ankle mortise must be evaluated carefully to determine if fibular frx in question is part of joint injury or merely                 frx assoc … Read more

TKR – Posterior Cruciate Ligament Retaining Prosthesis

X rays: for Tibial Frx

– comminution:     – more than 50% cortical comminution is considered significant and increases chance of non union; – displacement:     – > 50% frx displacement will significantly increase risk of non-union, due to instability of frx and predisposition for future displacement (if treated closed); – accetable reduction:     – > 10 deg … Read more
