5 special tests for the ankle likely to be in exam

A

Ligamentous injury

  • anterior drawer test
  • talar tilt test

Misc

  • Thompson
  • Tibial Torsion
  • Leg length discrepancy
92
Q

Talk to me about the anterior drawer test

A
  • Procedure: PT stabilizes distal tibia and fibula while other hand holds foot in 20 degrees of PF and draws talus forward in ankle mortise
  • Positive test: excessive anterior translation of talus away from ankle mortise. May indicate ATFL sprain
93
Q

Now talk to me about the talar tilt test

A
  • Procedure: PT stabilizes distal tibia w/ one hand while grasping talus w/ other hand. Foot maintained in neutral position. PT tilts talus into abduction and adduction
  • Positive test: excessive adduction may indicate CFL sprain
94
Q

Thompson test. Go!

A
  • Procedure: pt. prone w/ foot off edge of table. PT asks pt. to relax and then squeezes muscle belly of gastroc and soleus
  • Positive test: absence of plantar flexion possibly indicating Achilles tendon rupture
95
Q

What is the Tibial Torsion test

A
  • Procedure: pt. positioned sitting w/ knees over edge of table. PT places thumb and index finger of one hand over medial and later malleolus. PT then measures acute angle from by the axes of knee and ankle
  • Results: normal lateral rotation of tibia is 12-18 degrees
96
Q

The True Leg length Discrepancy test. Go!

A
  • Procedure: pt. supine w/ LE 15-20 cm apart and pelvis in balance w/ LEs. PT measures each LE from distal point of medial malleoli to ASIS
  • Positive test: with bilateral comparison, discrepancy between LE is greater than 1 cm.
