The Correct Option is A
Solution and Explanation
Step 1: A fall on an outstretched hand transmits force up the wrist. In older adults, especially post-menopausal women with osteoporotic bone, this force most commonly fractures the distal radius, the broad bone of the forearm that forms the major part of the wrist joint.
Step 2: A distal radius fracture presents with rapid pain, swelling, bruising and often a visible wrist deformity. The marked bone numbered 1 corresponds to the distal radius, so option 1 is correct.
Step 3: Specific named patterns of distal radius fracture include the Colles fracture (dorsal angulation), the Smith fracture (volar angulation), the Barton and the Hutchinson (radial styloid) fractures. The other numbered bones do not represent the radius and are not the commonest bone to break in this mechanism in adults.
