Anatomy study note · Lower limb

Tibia

The large, weight-bearing medial bone of the leg.

Key points

• Weight-bearing bone; condyles = tibial plateaus.
• Tibial tuberosity ← ligamentum patellae.
• Subcutaneous medial surface → open fractures.
• Distal-third fractures: delayed union.
• Medial malleolus at its lower end.
• Shaft: primary centre; ends: secondary centres; growth at the epiphyseal plate.
• Limb bones: limb-bud mesenchyme, endochondral (except clavicle).
• Long bone: endochondral ossification; epiphyseal plate closes ~20 y.
• Bone: type I collagen + hydroxyapatite.
