  1. Peroneal Tendons function? 2
  2. Posterior Tibialis Muscle function? 2
A

1.

  • Laterally provide resistance to inversion injuries

2.

  • Antagonist to the peroneals
  • Provides resistance to Eversion stresses
64
Q

Medial ligament injuries

  1. Medial structures are less likely to be injured because?
  2. Results from?
A
  1. of the more prominent bony barriers to eversion
  2. Result from ankle external rotation and eversion
65
Q

Ligament sprains tend to occur when the joint is in a position that provides little bony stability. In the ankle this is what? 2

Describe the mechanism of injury?

A
  1. Plantar Flexion and Inversion

2.

Talus is narrower posteriorly than anteriorly and in dorsiflexion the wider talus engages the mortise with a tighter fit

Inversion is less stable because of the lengths of medial and lateral malleoli differ

Lateral malleolus extends further distally and blocks lateral talar movement

In this position ligament injuries will occur
