Spring 2 Flashcards
Lower half of body sequence
Leg restrictors Pubes Superior innominate Upslip (shear) Lumbar Spine Sacrum Innominate Iliopsoas Lower Extremity
What are the leg restrictors
- ILIOPSOAS*
- QUADRICEPS
- PIRIFOFORMIS
- HAMSTRING
- ADDUCTORS
- ABDUCTORS
- QUADRATUS LUMBORUM*
- GLUTEUS MEDIUS
What structures that are NOT leg restrictures can also influence the lumbar-sacral-pelvic region?
- Rectus abdominus
- Diaphragm
- Multifidus
- Iliolumbar ligament
- Sacrotuberous ligament
- Sacrospinous ligament
What are the position/motion of the tibia?
Anterimedial and posteriolateral rotation
What are the position/motion of the fibula?
anterior and posterior glide
What are the position/motion of the talus?
anterior and posterior plantar/dorsiflexion
What are the position/motion of the subtalus
Inversion/eversion glide
What are the position/motion of the navicular
Medial and inferior glide
What are the position/motion of the cuboid
lateral and inferior glide
What are the position/motion of the cuneiforms
plantar position. plantar inferior glide
What are the position/motion of the metatarsals
adduction, abduction, plantar/dorsiflextion, rotation
What is the lower extremity scan sequence?
Knee Internal/External Tibial torsion Fibular Head Midshaft Interosseous Ankle/Foot Talus Subtalar Tarsal Metatarsal
In addition to anterior and posterior motion of the fibula which oblique motion is correlated correctly?
anterior and medial (dorsiflexion)
posterior and lateral (plantarflexion)
What is the direction of the angle of a valgus joint?
Medial (in valgus, the extremity distal to the joint is lateral)
Importance of common fibular nerve.
Wraps around posterior part of fibula
Sensitive to trauma, fracture or posterior fibular head dysfunction
Injury at knee can produce weakness of dorsiflexors and foot drop (supplies (motor) anterior–deep fibular-and lateral—superficial fibular– compartment of the leg, sensation to anterolateral leg)
Importance of common tibial nerve
Posterior compartment of the leg
Muscles of the foot
Generally disrupted in ankle inversion or supination sprain
Grade I –anterior talofibular
Grade II –add calcaneofibular
Grade III– all lateral ligments torn
(Anerior talofibular, Posterior talofibular, Calcaneofibular ligament)
Anterior tendons of the foot
Anterior Tibialis Tendon Supports transverse arch Extensor Digitorum Longus Extensor Hallicus Longus “Tom, Dick, and Harry”
Tendons Posterior to Lateral Malleolus
Fibularis Brevis
Fibularis Longus
Supports transverse arch
Longitudinal Arches of foot
Lateral
Calcaneus, cuboid, and metatarsals 4 and 5
Medial
Talus, navicular, three cuneiforms, metatarsals 1-3
Transverse Arch of foot
Cuboid, navicular, three cuneiforms, and metatarsal bones
Plantar Ligament Support
Plantar Aponeurosis
Long plantar ligament
Short plantar ligament
Spring ligament
Subtalar joint
- Talocalcaneal joint
- Stabilized by talocalcaneal ligament
- Moves anteromedially with calcaneal eversion and posterolaterally with calcaneal inversion and articlulates with tarsal bones
- Main shock absorbing joint in running
Intertarsal joints
Chopart’s joints
Talonavicular, cuboidocalcaneal, talocalcaneal (small)
Gliding motions at the knee
Lateral/Medial
Anterior/Posterior
Anteromedial (EXT rot)/Posterolateral (INT rot)
Fibular head motion
