Ligaments - between every
joint
• 1. Spring ligament (calcaneonavicular)
supports the medial longitudinal arch
• 2. Plantar facia - runs from the heel to
the toe. Originates on the medial
tubercle of the calcaneous, and
attaches to the metatarsal heads. Band
of thick fibers acts somewhat like arch.
Plantar Faciitis
• Etiology:
– Repetitive stress (traction) during weight
bearing and/or push off
– predisposing factors: rigid pes cavus,
shortened achilles tendon, hypermobile
forefoot
• Pathology:
– Microtrauma/inflammation at the insertion
of the plantar fascia into the calcaneous
with w/out bony exostosis formation
(calcaneal spur)
Plantar Facitis Cont.
– Signs & Symptoms

hyperextension of MP joints

spur)

starts, recovery from jump)
• Tight shoes, lateral compression of met heads
and interdigital nerves

neuroma minus neurological symptoms
Interdigital

calcis with w/out fragmentation of the
Apophysitis

• Signs & Symptoms
–
–
–
–
Antalgic gait - heel pain during running/walking
swelling
localized pain/tenderness
positive active/passive ROM test for tight achilles
tendon
• Calcaneal Extosis: need to differentiate
between Apophysitis
Fractures of Calcaneous

Ankle Anatomy
• . Muscles -• Gastroc - plantarflexion
• Soleus - plantarflexion
• Anterior Tibialis - Dorsiflexion
• Medial - Posterior tibialis, Flexor digitorum
Longus Hallux longus (Plantarflexion/inversion)
• Lateral - Peroneals (Dorsiflexion/eversion)
Ankle Anatomy
• Ligamentous Anatomy
– Deltoid Ligament
– Anterior Talo-Fibular Ligament
– Calcaneofibular Ligament
– Posterior Talo-Fibular Ligament
– Ant/Post Tib-Fib
Sprains
– Inversion Sprain - Supination and inversion
(stepping off a curb)
• 1st degree - mild swelling discomfort not
necessarily disability anterior talo-fibular
ligament
• 2nd degree - Some dysfunction, some joint
laxity and increased swelling
– Inversion test
– Anterior Drawer - shift talus forward
– Stress X-ray - Physician may do this for the angle
between the talus and tib/fib
Sprains
• 3rd degree - Greater laxity, more often involves
PTF
• ** If in doubt of the severity and gait is
compromised put the individual on crutches,
and RICE
Eversion Sprain - Disruption of
The Deltoid ligament, eversion
and pronation
• Treat the same as Inversion Sprain
• If excessive eversion may fracture the
fibula (lateral Maleoli)
Rotation Sprain- Hyperflexion
(Dorsiflexion) - Disruption of
Tib-Fib
• 1. Land in hyperflexion (jump off
something)
• 2. Rotation and plantarflexion
• 3. Test - Compression/distraction
• 4. Takes longer to heal because every
time the individual steps the tib-fib
ligament is re-irritated.
Avulsion Fracture - Ligament
pulls off a piece of bone
Instead of disrupting the
ligament.
• 5th Metatarsal styloid fracture (Jones
Fracture)
• Peroneal tendon of the peroneus
brevis pulls of a piece of the 5th
metatarsal.
– Mechanism - step on
– accompanied with inversion sprain
– Treatment - casted/immobilized
Subluxing peroneals
– Peroneals pop back and forth over the
peroneal tubercle
– Mechanism
• acute
• chronic - due to shallow peroneal tubercle
– Signs/symptoms - popping and pain on
eversion
– Treatment - conservative strengthen
peroneals
– Surgical - not often
Achilles Rupture
• Mechanism - acute over stretch (3rd
degree strain) or due to hit (3rd degree
contusion)
• Signs and Symptoms - Complain "kick
in calf" ,Ball under the knee, not
particularly painful
• Treatment - 72 hours until it starts to
degenerate and more difficult to
surgically reattach
• Thompson test
Ankle Dislocation - Talus
comes out of the mortise,
• Mechanism - same as ankle sprains
• Signs and Symptoms - Deformity
• Treatment - Closed reduction by
physician, sometimes surgical
