Tibio-fibular joint

Ox

• The bony fibula is replaced by a ligament for most of its extent and thus the proper tibio-fibular articulation is absent.
• The upper end of the fibula fuses with the lateral tuberosity of the tibia.
• The lower end ossifies as a separate piece of bone and forms a diarthrosis with the lower end of the tibia.
• Motion
  • Inappreciable as two bones are closely united by strong short fibres.

Horse

• It forms a diarthrosis and an amphiarthrosis.
• The former is between the head of the fibula and the lateral condyle of the tibia.
• It has a tight capsular ligament.
• The amphiarthrosis is between the shafts of the bones and has an interosseous ligament.

Dog

• Diarthrodial joints are formed between the bones at either ends, the shafts are united by interosseous ligaments.
