– Discussion: – usually result from direct blow; – presents w/ dorsal angulation & increased palmar displacement of metacarpal heads because of deforming force of interosseous muscles and long flexor muscles, which are volar to the fracture plane; – more proximal frxs (ie, shaft frx) are more likely to … Read more
