Attachments Flashcards
FLEXOR HALLUCIS BREVIS
Proximal Attachment: plantar surface of the cuboid and lateral cuneiform bones
Distal Attachment: both sides (medial and lateral) of the proximal phalanx of the great toe.
QUADRATUS PLANTAE
Proximal attachment: medial aspect of the plantar surface of the calcaneus.
Distal attachment: tendon of the flexor digitorum longus.
Quadratus Lumborum
Illiac crest, TP T12-L4 and Inferior border of 12th rib.
Flexor Hallucis Longus
Origin: middle half of posterior fibula
Insertion: base of distal phalanx of the great toe.
Lumbar Paraspinals – Iliocostalis Lumborum and Lx and Sx Multifidus
Iliocostalis Lumborum:
O- Thoracolumbar aponeurosis, sacrum and iliac crest
I – Transverse process of L1-3 and posterior surface of rib 12-6
Multifidus
O – Posterior sacrum and mammillary process of L1-5
I – Spinous processes spanning 2-4 vertebrae
EXTENSOR DIGITORUM BREVIS
Proximal Attachment: superior aspect of calcaneus
Distal Attachment: divides into three tendons, inserting into the lateral aspects of the extensor digitorum longus tendon if the 2nd – 4th toes.
ABDUCTOR HALLICIS
Proximal Attachment: medial process of the tuberosity of the calcaneus, the flexor retinaculum, the plantar aponeurosis
Distal Attachment: medial or plantar side of the base of the proximal phalanx of the great toe
Flexor Digitorum Longus
Origin: middle posterior surface of the tibia deep to the gastrocnemius & soleus
Insertion: base of the distal phalanx of the four lateral toes
Gluteus Maximus
Proximal attachment: gluteal surface of the ilium, lateral surface of sacrum, coccyx and sacrotuberous ligament.
Distal attachment: iliotibial band of the fasciae latae (75%), and the gluteal tuberosity of the femur (25%).
Gluteus Medius
Proximal attachment: external surface of the ilium between the posterior and anterior gluteal lines
Distal attachment: lateral surface of the greater trochanter
Gluteus Minimus
Proximal attachment: on the ilium between the anterior and the inferior gluteal lines
Distal attachment: the anterior superior aspect of the greater trochanter of the femur
Piriformis
Proximal attachment: anterior surface of the sacrum
Distal attachment: upper border and medial aspect of the greater trochanter of the femur
Iliopsoas
Origin:
Psoas major – bodies and transverse processes of the lumbar vertebrae
Psoas minor (present in only 50% of people) – lateral portion of T12 to L2
Iliacus – iliac fossa
Insertion:
Psoas major and iliacus – lesser trochanter of the femur
Psoas minor – superior ramus of the pubis
Tensor Fascia Latae
Proximal Attachment: anterior iliac crest just posterior to the anterior superior iliac spine.
Distal Attachment: through the iliotibial band to the lateral condyle of the tibia.
Sartorius
Proximal Attachment: ASIS
Distal Attachment: Pes anserine attachment site
