AB The  tibia  is  the  only  weight-bearing  bone  in  the  leg.  The  fibula  is  bound  to  the  tibia  by  the  interosseous  membrane,  which  divides  into  a  "Y"  both  proximally  and  distally.  The  proximal  arm  of  the  "Y"  is  composed  of  the  anterosuperior  tibiofibular  ligament  and  the  posterosuperior  tibiofibular  ligament.  A  similar  division  occurs  distally  with  an  anteroinferior  tibiofibular  ligament  and  a  posteroinferior  tibiofibular  ligament.  The  upper  portion  of  the  fibula  is  of  little  importance  and  can  be  excised  with  little  consequence.  The  lower  portion  cannot  because  of  its  importance  in  forming  the  ankle  mortise.
