KP221 Lecture Notes - Lecture 12: Linea Aspera, Greater Trochanter, Superior Gemellus Muscle
KP221 – L12
Rotational force
Tibialis posterior syndrome: can not jump up, fallen arches
Sciatica: disc herniation, or tight piriformis
Trendelenburg test: gluteus medius
Positive test: stand on right and the left hip will sag
The right will be weak
Lower back pain - iliopsoas
Iliopsoas pain: check out gluteus maximus, groin pull
Calf pain: gastrocnemius and and soleus
Quad injuries: if rectus femoris is injured you will have to flex the knee and put the hip at
extension so it is stretching
Medialis = turn foot out
Lateralis = turn foot in
Rectus femoris = extension at hip
Patella femoral syndrome: vastus lateralis is biggest muscle on anterior leg so
strengthen vastus medialis to pull back the knee by vastus lateralis
Foot - Second layer
Quadratus Plantae
Origin: medial surface and lateral margin of calcaneus at its plantar surface
Insertion: posterolateral margin of flexor digitorum longus tendon
Action: assist flexor digitorum longus
Flexes lateral 4 digits
Lumbricals
Origin: tendons of flexor digitorum longus
Insertion: medial aspect of expansion over lateral four digits
Action: flex proximal phalanges
Extend middle and distal phalanges of lateral four digits
Third layer
Flexor Hallucis Brevis
Origin: plantar surfaces of cuboid and lateral cuneiform
Insertion: both sides of base of proximal phalanx of 1st digit
Action: flexes proximal phalanx of 1st digit
Adductor Hallucis
Origin: oblique head
Bases of metatarsals 2-4
transverse head: plantar ligaments of 3rd-5th metatarsophalangeal joints
Insertion: lateral side of base of proximal phalanx of 1st digit
Action: adducts 1st digit
Maintains transverse arch of the foot
Flexor digiti minimi brevis
Origin: base of 5th metatarsal
