The common peroneal nerve branches from the sciatic nerve behind the knee and becomes superficial as it wraps around the lateral head of the fibula.At this level,it is quite vulnerable to direct compression by stirrup bars.This risk increases in extremely thin patients who have minimal overlying tissue in this area.Compressive leg wraps (i.e.,pneumatic compressive devices,elastic wrappings,or stockings)also can apply pressure on this nerve if the wrapping is too tight in this area.
