Document Summary

Important for lots of different professions kin, orthopaedics, physiotherapy, athletic training, nursing: problem solving, lots of memorization, upper vs lower limb, upper and lower limb have similar overall arrangement, but adapted to serve unique features. In quadrupeds, all 4 limbs served purpose of stabilization and locomotion. In bipeds, evolved to that the lighter upper limb does complex, fine movement (grasping, reaching) while heavier lower limb does powerful movements and supports weight during walking and running, etc. Scaphoid bone has poor blood supply and if it gets fractured it is very difficult for it to heal.

If it is broken, often surgery is needed to fix it. For the center of gravity it makes the muscles work less so that there is less stress and less muscular energy being used. Bone graft for other part of the body will take the head of the fibula to graft.
