The Correct Option is A

Solution and Explanation


Step 1: Understanding the Concept:

Bovine pedal orthopedics: fracture of the medial claw 3rd phalanx (pedal bone) causes the animal to cross the contralateral foreleg to shift weight bearing.

Step 2: Detailed Explanation:

In bovine orthopedic surgery:
- In Cattle, the medial claw of the forelimb bears the major proportion of static body weight.
- When a fracture of the 3rd phalanx (pedal bone coffin bone distal phalanx) occurs (frequently in the medial fore-claw), the animal experiences acute weight-bearing pain.
- To shift weight off the fractured medial digit onto the lateral digit of the opposite limb, the cow characteristically crosses the injured foreleg across the midline over the sound foreleg (cross-legged posture).

Step 3: Final Answer:

Thus, crossing the forelegs occurs during 3rd phalanx fracture in Cattle, corresponding to option (A).
