Fx Classification

Question 1

clavicle; Group 2, Type I fx

Answer 1

lateral third and lateral to CC ligs w/o lig involve = no displacement

Question 2

clavicle; Group 2, Type IIa fx

Answer 2

lateral third and medial to CC ligs w/o lig involve = no displacement, most need ORIF

Question 3

clavicle; Group 2, Type IIb fx

Answer 3

lateral third and between CC ligs w/ conoid lig involvement and no trapezoid lig involvement = medial frag elevated, most need ORIF

clavicle; Group 2, type III fx

Answer 4

lateral third and ACJ involvement w/o displacement; can be missed => OA ==> resection arthroplasty
