foot and toes Flashcards
- what bones are in the rear foot?
- what bones are in the mid foot?
- what bones are in the forefoot? MT
- Talus and calcaneus
- navicular, cuboid, and medical, intermediate, lateral cuneiform bones.
- metatarsals and phalanges.
what are the 3 regions of the foot?
rear, mid, forefoot
what is the function of the ankle?? MT
- shock absorption
- adaptation to uneven terrain
- propulsion of our body through space.
- stability for keeping body upright.
what are the 6 classifications of joints in the foot? MT
- subtler joint (talocalcaneonavicular joint)
- talonavicular joint.
- calcaneocuboid joint
- tarsometatarsal joint
- metatarsophalangeal join
- interphalangeal joint
what are the 3 arches of the foot and which bone is the point of reference for them? MT
medial longitudinal arch
- navicular bone
lateral longitudinal arch
transverse arch
- 2nd metatarsal
what are 4 main passive supporting structures of the foot? MT
- plantar fascia
- spring ligament (plantar calcaneonavicular)
- long plantar (long plantar calcaneocuboid)
- short plantar (short plantar calcaneocuboid)
what is the difference between extrinsic and intrinsic foot muscle?
extrinsic
- muscles in the lower leg that cross the ankle into the foot because of their muscle bellies, and exit on the outside of the foot.
intrinsic
- have both attachments that are contained within the ankle. muscles do not cross the talaco joint.
what is an overview of a fracture of the talus? MT
- cause by acute hyper-dorsiflexion with inversion.
- fracture of the lateral process and neck of the talus.
s/s for fracture of the talus? MT
- severe posterior pain when jumping, running, or kicking.
- pain is increased on force of plantar or dorsiflexion.
- increased pain with resisted flexion of the great toe, bc of insertion point of flexor hallucinations longs tendon.
- mod to sev swelling, tenderness, and dicoloration.
what is management for a fractured talus?
immediate immobilization of the talus and refer to a physician.
what is the overview of a calcaneus fracture? MT
- they are high-energy axial loads. (failing from a height and landing on the bottom (flat feet))
- factures occire at the anterior process by forceful plantar flexion or compression.
list the s/s of a calcaneus fracture? MT
-severe heel pain
- inability to walk or weight bear.
- palpable intense pain over the process of the calcaneus.
how do you manage a calcaneus fracture?
- immobilization
- ice and elevation to control edema.
- short leg cast or walking boot for 6 weeks.
- repair by surgery, patient experiences stiffness of the subtalar joint.
how can stress fractures develop? MT
- running and jumping activities.
- increase in training mileage
- change in surface, hard to soft to uneven.
- change in intensity.
- change in shoe type.
what is the difference between non-critical and critical stress fracture?
non-critical
- fracture of medial tibia, fibula, 2,3,4 metatarsal.
critical
- fracture of anterior tibia, medial malleolus, talus, navicular, 5th metatarsal, sesamoids.
what are the s/s of stress fractures? MT
- pain begins insidiously, and progressively gets worse over time.
- pain limited to the fracture site.
- prolonged pain.
which bones can be irritated in a stress fracture, and with which movements. MT
talus
- excessive pronation
calcareous
- excessive heel strikes
navicular
- jumping, ballet dancers.
how do you manage a stress fracture?
- x-rays
- bone scans and MRI
- person needs to go through the full process of doing weight bearing actives as per to how the bone is healing.
- rest, stretching, strengthening.
- protected weight bearing, stiff shoe or walking cast.
what is severs disease?
- seen in 7-10 yr olds
- associated with growth spurts, decreased flexibility of hamstrings and tricep surae.
- open growth plates
what causes sever disease?
hards surfaces
poor shoes
kicked in the region or landing off balance.
