Foot Flashcards
Plantar fascitis
- what is it
- causes
plantar aponeurosis inflammation at the proximal attachment (calcaneus)
- caused by running, high impact exercise, worn out shoes, overweight
plantar fascitis can lead to ____
heel spur syndrome
- bony process develops
hallux valgus
- what is it
- caused by
foot deformity characterized by lateral deviation of the great toe
- surrounding tissues swell and pressure and fiction cause a bursa to form (pointy shoes)
- normally also has bursitis and corns
bunion
tender and inflammed bursa
corns
inflamed areas of thick skin over proximal interphalangeal joints of the foot
mallet toe is characterized by ____
flexion in the distal interphalangeal joint
hammer toe is characterized by ____
extension at the metatarsophalangeal joint and flexion at the proximal interphalangeal joint
claw toe is characterized by ______
extension at the metatarsophalangeal joint and flexion at both the proximal and distal interphalangeal joints
trigger toe is characterized by ______
extension of the metatarsophalanglea joint and flexion of interphalangeal joints of the big toe
common cause of mallet toe, hammer toe, claw toe, and trigger toe
shortened flexor muscles which can override lumbrical function
hammerlike deformity of the second digit is characterized by _____
proximal phalanx is permanently hyperextended at MP joint, middle phalanx is plantar-flexed at PIP joint, distal phalanx is extended
how does the medial plantar n. terminate
by dividing into 4 sensory branches that supply the medial three digits and half of the fourth digit
how does the lateral plantar n. terminate
by dividing into superficial and deep branches
what supplies cutaneous innervation to the lateral 1/2 of the 4th digit and the 5th digit
superficial branch of the lateral plantar n.
