|
|
Primary hip flexor.
|
Iliopsoas.
|
|
Primary knee extensor.
|
Quadriceps.
|
|
Primary knee flexors.
|
Semimembransis and semitendinosis.
|
|
ACL
|
Originates: anterior part of intercondylar area of tibia (just posterior to medial meniscus attachment).
Inserts: (extends superiorly, posteriorly, laterally) posterior part of medial side of lateral condyle of femur. Prevents posterior displacement of femur on tibia and hyperextension of knee. |
|
PCL
|
Origin: posterior part of intercondylar area of tibia.
Insersion: Anterior part of lateral surface of medial condyle of femur. Prevents anterior displacement of femur and hyperflexion of knee. |
|
Medial collateral ligament.
|
-medial epicondyle of femur to medial condyle and superior medial surface of tibia.
-deep fibers attach firmly to medial meniscus. |
|
Lateral collateral ligament
|
-extends from lateral epicondyle of femur to lateral surface of head of fibula.
|
|
Fibular head moves ____ w/ pronation (dorsiflexion, eversion, and external rotation) of foot.
|
anteriorly.
|
|
Fibular head moves _____ w/ supination (plantarflexion, inversion, internal rotation) of foot.
|
posteriorly
|
|
Femoral nerve.
|
L2-L4
Motor: Innervate quadriceps, iliacus, satorius, pectineus. Sensory: anterior thigh and medial leg. |
|
Sciatic nerve: tibial division.
|
L4-S3
Motor: hamstrings (except short head of biceps femoris), most plantar flexion, and toe flexors. Sensory: lower leg and plantar aspect of foot. |
|
Sciatic nerve: peroneal division.
|
L4-S3
Motor: short head of biceps femoris, evertor and dorsiflexors of foot, and most toe extensors. Sensory: lower leg and dorsum of foot. |
|
L1

Motor: Iliopsoas.
Reflex: none Sensation: anterior thigh just below inguinal ligament. |
|
L2
|
Motor: iliopsoas, adductors, quadriceps

|
L3
|

|
L4
|
Motor: anterior tibialis
Reflex: patella reflex. Sensation: medial malleolus. |
|
L5
|
Motor: external hallicus longus, quadriceps
Reflex: None Sensation: dorsal aspect of foot and big toe. |
|
S1
|
Motor: peroneus longus and brevis gastrocnemius.
Reflex: Achilles reflex. Sensation: Lateral malleolus. |
|
Posterior fibular head dysfunction.
|
Restriction in anterior glide.
Foot be more supinated. Fibular head resist any anterior springing. Often disturb common fibular nerve, as it directly lies posterior to the proximal fibular head. |
|
Anterior fibular head dysfunction.
|
Restriction in posterior glide. Foot be more pronated.
Fibular head resist any posteror springing. |
|
Ankle is more stable in dorsiflexion or plantarflexion?
|
Dorsiflexion.
|
|
Joint for dorsiflexion / plantarflexion.
|
Tabiotalar joint.
|
|
Transverse arch of foot.
|
Cuboid, cuneiforms, navicular.
|
|
Most commonly injured ligament in foot.
|
Anterior talofibular ligament.
|
|
Lateral stabilizers of ankle (prevent excessive supiantion)
|
Anterior talofibular ligament.
Posterior talofibular ligament. Calcaneofibular ligament. |
|
Medial stabilizer of ankle.
|
Deltoid ligament.
|
|
Plantar ligaments.
|
Spring ligament (calcaneonavicular ligament)
