摘要: This study quantified the torsional resistance provided by locking plates and angled blade used to stabilize proximal humeral fractures. Three-part fractures were created in 6 pairs of cadaveric humeri. One specimen each pair was reconstructed with a plate, whereas other an plate. An external rotation torque, varying from 0 5 N-m, applied head until rotated 30° or 10,000 loading cycles applied. The mean initial stiffness significantly larger for (0.99 N-m/degree) than (0.59 N-m/degree). For pair, maximum plate this vitro model 3-part fracture, better fatigue
