Question

one of mrs. morgans fractures is described as being located on the proximal diaphysis. which of these phrases best describes the anatomical location of this fracture?
shaft of the bone closest to the shoulder joint
expanded end closest to the shoulder joint fractured
expanded end closest to the elbow joint fractured
shaft of the bone closest to the elbow joint

Explanation:

• The diaphysis refers to the shaft of a long bone.
• "Proximal" means closer to the point of attachment (in the case of limb bones, closer to the body trunk). For an arm - related bone (assuming a typical long - bone in the arm context), the shoulder joint is closer to the body trunk compared to the elbow joint.

Answer:

shaft of the bone closest to the shoulder joint
