00:00:02.059 --> 00:00:07.109
To ensure a thorough assessment, it is best
to perform the musculoskeletal exam of the

00:00:07.109 --> 00:00:09.051
ankle and foot in a systematic way.

00:00:09.051 --> 00:00:13.079
The following is a suggested order of examination
that incorporates the common techniques for

00:00:13.079 --> 00:00:17.009
diagnosing ankle and foot injuries.

00:00:17.009 --> 00:00:19.082
Begin with the standing evaluation of the
foot anatomy.

00:00:19.082 --> 00:00:25.006
Look for muscular atrophy, skin changes, or
anatomic variance, such as pes planus, pes cavus,

00:00:25.006 --> 00:00:32.085
or bunion formation.

00:00:32.085 --> 00:00:37.329
From a posterior view, observe for more than
two toes laterally, also called the 'too-many-toes'

00:00:37.329 --> 00:00:41.046
sign, which can indicate overpronation or
an abducted foot.

00:00:41.046 --> 00:00:44.649
Have a patient perform a toe raise and evaluate
for heel positioning.

00:00:44.649 --> 00:00:50.469
Normally the heel should change from a neutral
to a varus position.

00:00:50.469 --> 00:00:54.051
Observe gait as the patient walks away from
and towards the examiner.

00:00:54.051 --> 00:01:04.028
Look for an antalgic gait or excessive pronation
or supination.

00:01:04.028 --> 00:01:06.469
Next evaluate active range of motion.

00:01:06.469 --> 00:01:14.001
If pain or limitation exists, repeat passive
range of motion.

00:01:14.001 --> 00:01:23.599
First check dorsiflexion, plantarflexion,
inversion, eversion, great toe dorsiflexion,

00:01:23.599 --> 00:01:26.749
and great toe plantarflexion.

00:01:26.749 --> 00:01:39.013
Now check resisted strength with dorsiflexion,
plantarflexion, inversion, eversion, great

00:01:39.013 --> 00:01:45.779
toe dorsiflexion, and great toe plantarflexion.

00:01:45.779 --> 00:01:58.649
Palpate anatomic landmarks for tenderness:
the calf belly; the Achilles tendon for Haglund's

00:01:58.649 --> 00:02:15.065
deformity; along the tibia, checking for any
areas of tenderness; the medial malleolus;

00:02:15.065 --> 00:02:30.065
the deltoid ligament; the tarsal tunnel; the
posterior tibial muscle and tendon; the navicular

00:02:30.065 --> 00:02:47.379
bone and tubercle; the fibula, including the
fibular head; the lateral malleolus; the anterior

00:02:47.379 --> 00:02:56.969
talofibular ligament; calcaneofibular ligament
and posterior talofibular ligament; the peroneal

00:02:56.969 --> 00:03:15.159
tendon; the talar dome; the calcaneus and
calcaneal fat pad; the plantar fascia; the

00:03:15.159 --> 00:03:36.003
metatarsal heads; the base of the fifth metatarsal;
the sesamoid bones; and the phalanges, or

00:03:36.003 --> 00:03:37.959
toes.

00:03:37.959 --> 00:03:42.069
Specific testing for the ankle and foot to
evaluate for injuries may include, but is

00:03:42.069 --> 00:03:45.092
not limited to, the following tests.

00:03:45.092 --> 00:03:51.109
The squeeze test evaluates for a syndesmotic
ankle injury. With the foot dorsiflexed, the

00:03:51.109 --> 00:03:53.051
tibia and the fibula are squeezed together.

00:03:53.051 --> 00:03:54.093
Pain is a positive test.

00:03:54.093 --> 00:04:00.093
Kleiger's test also evaluates for a syndesmotic
injury. With the knee fixed, the foot is dorsiflexed

00:04:00.093 --> 00:04:02.009
and externally rotated.

00:04:02.009 --> 00:04:07.079
Pain is a positive test.

00:04:07.079 --> 00:04:12.269
The anterior drawer test is for anterior talofibular
ligament stability. With the foot slightly

00:04:12.269 --> 00:04:15.045
plantarflexed, brace the shin and pull the
heel anteriorly.

00:04:15.045 --> 00:04:21.949
Laxity or poor endpoint is a positive test
and indicative of anterior talofibular injury.

00:04:21.949 --> 00:04:27.003
The talar tilt test assesses for both anterior
talofibular ligament and calcaneofibular ligament

00:04:27.003 --> 00:04:28.009
stability.

00:04:28.009 --> 00:04:32.000
With the foot slightly plantarflexed, brace
the heel and invert the foot.

00:04:32.000 --> 00:04:35.003
Repeat on the opposite side and compare degrees
of inversion.

00:04:35.003 --> 00:04:39.019
Inversion of more than twenty three degrees,
or more than five degree difference, is a

00:04:39.019 --> 00:04:45.819
positive test and indicative of anterior talofibular
and calcaneofibular ligament injury.

00:04:45.819 --> 00:04:50.043
The calcaneal squeeze test evaluates for calcaneal
injury, such as a stress fracture.

00:04:50.043 --> 00:04:52.091
Apply a compressive force on the calcaneus.

00:04:52.091 --> 00:04:55.043
Pain is a positive test.

00:04:55.043 --> 00:05:00.006
The midfoot torsion test assesses for midfoot
injuries, such as Lisfranc sprain.

00:05:00.006 --> 00:05:02.919
Stabilize the hind foot and rotate the midfoot.

00:05:02.919 --> 00:05:05.033
Pain is a positive test.

00:05:05.033 --> 00:05:08.099
Mulder's test evaluates for Morton neuroma.

00:05:08.099 --> 00:05:12.061
The first and fifth metatarsal heads are grasped
and squeezed together.

00:05:12.061 --> 00:05:14.068
Pain or paresthesia is a positive test.

00:05:14.068 --> 00:05:19.006
If an audible click is heard, it's called
a Mulder's sign and indicative of a fibrotic

00:05:19.006 --> 00:05:21.036
neuroma.

00:05:21.036 --> 00:05:25.077
Perform a Tinel's over the tarsal tunnel,
attempting to reproduce pain, numbness, or

00:05:25.077 --> 00:05:31.289
tingling caused by tarsal tunnel syndrome.

00:05:31.289 --> 00:05:36.000
In a prone position, Achilles tendon stability
can be assessed using Thompson's test.

00:05:36.000 --> 00:05:40.449
Flex the knee to ninety degrees, squeeze the
calf, and observe for plantarflexion of the

00:05:40.449 --> 00:05:41.005
foot.

00:05:41.005 --> 00:05:45.009
Absence of plantarflexion indicates Achilles
tendon rupture.

00:05:45.009 --> 00:05:49.043
In concluding the ankle and foot exam, it's
important to document neurovascular.

00:05:49.043 --> 00:05:55.799
Here we demonstrate dorsalis pedis pulse,
posterior tibial artery pulse, and capillary refill.

00:05:55.799 --> 00:05:59.010
Further neurovascular exam may be indicated
by history.

00:05:59.010 --> 00:06:00.330
