Answer-A. Tension band wiring
The given X-ray shows disploced transversefracture ofpatella, which is treated by tension band wiring.
“Displaced transversefracture: The lateral expansions are torn and the entire extensor mechanisns is disrupted. Operation is essential. Through a longitudinal incision the.fracture is exposed and the patella repaired by the tension-band principle.
Thefragments are reduced and transfixed with two stiff K-wires;flexible wire is then looped tightly around the prolruding K-wires and ouer thefront ofthe patella.
