Removal of the tendon of the deep digita| f|exor musс|e has opened r.lpthe oodotroсh|ear bursa to reveaI the dista| sesamoid bone. PartiaIexсision of the roof of the podotroсh|ear bursa revea|s the synovia| сaviof the dista| interpha|angеa| joint. The сaгtilage сovering thepodotroсhlear surfaсе of the dista| sesamoid bone shows evidenсe ofpathoIogiсal changе (.naviсuIar' disеase).
