FOOT DIAGRAM
FOOT INJURIES

FRACTURES
Any break in a bone
LISFRAN FX- midfoot (distal 2-4 metarsals, cuniforms)
MOI-crush injury; rotation while planar flexed
STRESS FX- MOI-over use, RMI

SESAMOIDITIS
Bone imbedded into tendon of 1st metatarsal
Irritation due to overuse
Pain with “toe off”

DISLOCATIONS & SUBLUXATIONS
Complete tear of all ligaments
Partial tear of some or all the ligaments
Lisfran Fx & Sesamoiditis
FOOT INJURIES

SPRAIN
Stretch or tear of a ligament in foot
Midfoot most common
Stress test-twist foot

TENDON RUPTURES


TENDONITIS
overstretching or overuse
PRICE immediate care
stretching & conditioning
FOOT INJURIES

NEURITIS Irritation of the nerve
MORTON’S NEUROMA
Pain between 3rd & 4th metarsals & toes
Due to ill-fitting toes
TARSAL TUNNEL SYNDROME
Compression of nerves in ankle
Can cause burning or shooting pain in foot
Usually due to wearing high heels, cowboy boots, etc
FOOT INJURIES


BURSITIS
Between achilles tendon & talus
Pain-point tenderness, plantar flexion & toe off
PLANTAR FASCITIS
inflammation of tisue on sole of foot
repeated stress
pain increased with heel raises
PRICE immediate care
Stretching arch & calf muscles
HEEL SPUR
Extra calcium build up at the heel

Toenail grows in the skin
soak toe
cut “V” in top edge of nail
