Anatomy of the Femur, Patella, Tibia, and Fibula

Femur

• The femur is the longest bone in the human body.
• Its head fits snugly into the acetabulum of the hip, forming a ball and socket joint with its neck rotating within this joint.
• Trochanters:
  • Greater and Lesser Trochanters: These are points of attachment for hip ligaments and muscles.
  • Hip Dislocation: Dislocating the hip is extremely difficult and painful due to the tight network of ligaments and muscles holding the hip socket together.
  • Risks of Relocation: Attempting to pop a dislocated femoral head back into the socket can be dangerous, potentially causing an impacted fracture of the femoral head, which is difficult to heal and very painful.
• Distal End:
  • Distal Condyles: These articulate with the tibia.
  • Medial and Lateral Epicondyles: These are situated above the condyles and allow for the attachment of ligaments.
