Muscles Of Thigh And Hip Joint

Front 1

Stability of joints

Back 1

Articulating surfaces
Ligaments - fibrous ligaments prevent excessive movement
Muscle tone - helps control stability

Front 2

How would you examine the hip joint

Back 2

Patient supine position
Patient consent
Flexion
External abduction knee up
Internal addiction knee up
External abduction with pressure on opposite Asis
Internal abduction with pressure on opposite Asis.

Front 11

Pectineus

Back 11

Or: superior ramus of pubis
In: pectineal line infer to lesser trochanter
Femoral nerve: l2 l3
Adducts flexes thigh
Assists medial rotation

Front 12

Iliopsoas

Back 12

Iliacus

Papas minor

All flex thigh at hip joint and stabilises hip joint

Front 13

Iliacus

Back 13

Or: iliac crest, ala of sacrum, iliac fossa

In: pectineal line

Lumbar nerves l1-l2

Front 16

Sartorius

Back 16

Or: asis
In: sup. medial surface of tibia

Femoral nerve l2 l3

Hip joint: flexes, abducts and laterally rotates thigh

Knee joint: flexes leg, medially rotates leg when knee is flexes.

Medial muscles

Back 26

Adductor longus
Adductor breviary
Adductor Magnus
Gracillus
Obturator externus

Front 27

Adductor longus

Back 27

Or: body of pubis inferior to pubic crest
In: Middle third linea aspera
Obturator nerve l2,l3 and l4.
Adducts thigh

Front 28

Extends thigh

Front 32

Gracillus

Back 32

Or: body and inferior ramus of pubis
In: sip. Part of medial surface of tibia
Obturator nerve

Front 33

Obturator externus

Back 33

Or: margins of obturator Foramen
In: trochanteric fossa of femur
Obturator nerve

Front 34

Actions of adductor

Back 34

Pull thigh medially, toward or past median plane.
Three adductors (longus, Brevis and Magnus) used in all movements
Also stabilise stance when walking.
Contribute to flexion of extended thigh
Extension of flexed thigh

Testing of medial thigh muscles

Back 35

Individual is supine
Knee straight
Adduction of thigh against resistance
If adductors are normal, proximal ends of gracillus and adductor longus can be easily palpated
