Tension Band for Patella Frx

      – Discussion:     – theory of tension band wiring:     – modified anterior tension band technique is indicated for both transverse and comminuted fractures of the patella;     – for maximal strength, wires are placed on tension surface of bone (anterior surface), as compared to circumferential cerclage wiring;   … Read more
