DESCRIPTION OF TEST BEING
PERFORMED
|
Eversion Stress Medial Stress
|
Neutral plantarflexion to eversion |
Deltoid Ligament |
Knee is bent 900 and gastrocnemius is relaxed. The heel is held
from below by one hand while the other hand holds the lower leg. The hand on
the heel is placed somewhat inferior medial and is used to push the calcaneus
and talus into eversion while the other hand grips the lower leg laterally
and pushes medially. |
Side to Side Test
Transverse
Drawer Test
|
Neutral plantarflexion |
Anterior and Posterior Inferior Tibiofibular Ligaments Interosseous Membrane
|
Knee is flexed 900 and gastrocnemius is relaxed. Move the
calcaneous and talus to each side as a unit. Do not tilt the ankle. If
mortise is widened, the talus will be able to move sideways, producing a
definite thud as it hits the fibula, and when moved in the opposite
direction, it butts against the tibia. |
Anterior Drawer |
Slight plantarflexion |
Anterior Talofibular Ligament Anteromedial Capsule
|
Knee is flexed 900 and gastrocnemius is relaxed. One hand holds
the lower tibia and exerts a slight posterior force, and the other hand is
around the posterior aspect of the calcaneus and attempts to bring the
calcaneus and talus forward on the tibia. Also done by stabilization of foot
and talus on table and pushing tibia and fibula posteriorly. |
Posterior Drawer |
Slight Plantarflexion |
Posterior Talofibular Ligament |
Knee is flexed 900 and gastrocnemius is relaxed. One hand is
placed on the heel to stabilize it while the other hand is placed on the posterior
aspect of the lower leg. Attempt to bring the tibia forward on a fixed heel. |
Inversion Stress Lateral Stress
|
Neutral Plantarflexion 200 Plantarflexion
|
Calcaneofibular Ligament Calcaneofibular Ligament and Anterior Talofibular Ligament
|
Knee is flexed 900 and gastrocnemius is relaxed. The heel is
held from below by one hand while the other hand holds the lower leg. The
hand on the heel is placed somewhat inferior lateral and is used to push the
calcaneus and talus into inversion while the other hand grips the lower leg
medially and pushes laterally. Note an end point. |
External Rotation |
From neutral to external rotation of foot |
Anterior Inferior Tibiofibular Ligament Interosseous Membrane
|
Foot should be in neutral position with the lower leg stabilized. Examiner
should then internally rotate the foot. If this causes pain then must
consider a tear of the tibiofibular ligament. Depending on severity the
interosseous membrane may be involved. Pain will be at site of the anterior
tibiofibular ligament. |
Squeeze Test |
Below head of fibular |
Anterior Inferior Tibiofibular Ligament |
Perform the squeeze test just above the anterior tibiofibular ligament.
Squeeze the bones together firmly and slowly, hold and then quickly release. If
there is pain upon release at the area of the anterior tibiofibular ligament,
then a sprain of that ligament is highly suspected. |
Squeeze Test |
Up and down the shaft of the tibia and fibula. Foot is in a neutral,
relaxed position. |
Testing for fracture of tibia or fibular. |
Place the heel of each hand at equal height on the shaft of the tibia and
fibula, then push or squeeze the bones together. Pain above or below the
sight of the squeeze is indicative of a fracture. Test should be repeated
several times up and down the shafts of both bones. |
Heel Tap Test |
Foot is relaxed and in a neutral position |
Tibia & Fibula |
The foot is held relaxed by one hand in a somewhat neutral position, while
the heel of the other hand is used to tap or lightly hit the bottom of the
heel from an inferior to superior direction. Pain along the lower leg may
indicate a fracture of the tibia or fibula. |
