Fractures of the Foot• T_______ bones

– C___________• Direct contact (fall/jump)• Can be complete or stress

– T_________• Forced dorsiflexion• Susceptible to avasuclar necrosis and osteochondritis

dissecans

– M_______________• Transverse or spiral• Avulsion @ base of 5th

Metatarsal Fractures

Jones Fracture

March Fracture

Foot Strains and Sprains

• Arches– M_______

longitudinal arch• P________ fasciitis

– Heel spur syndrome

– M__________ arch• Repetitive stress

• P_________– Great toe MP joint

• “T______ Toe”

Contusions to the Foot

• C____________– “Heel bruise”– “Stone bruise”

SX:Pain often on lateral side of heel due to heel strike pattern

• Metatarsals– Usually at met heads– SX: pain on bottom of

the foot “balls of the feet”

Structural Conditions

longer than the Great toe

– Can lead to stress fractures and neuroma

• Hallux V________– Valgus stress on first

ray– Leads to b_________

Bunions

Structural Conditions

• H_________ Toes– Buckling of an IP joint– Commonly due to muscle

imbalance– Leads to calluses and

bunions
