What is Cephalomedullary nailing linked with?

1

Studies link Cephalomedullary nailing with 1 measure, most often hip abduction strength (1 study).

Hip abduction strength

downin humans1

1 study

  1. Cephalomedullary nailing is associated with hip abduction strength in humans (At 0 degrees: 7.7±3.5 versus 6.2±2.8 kg; at 10 degrees: 5.5±2.0 versus 4.2±2.0 kg, non-operative versus operative side).

    “abduction strength at 0 degrees 7.7±3.5/6.2±2.8 (p=0.002), abduction strength at 10 degrees 5.5±2.0/4.2±2.0 (p=0.001).”
