The Hip Flashcards
Learn about the hip muscles and their function
What are the 3 regions of the hip? And their relative % of the acetablum
Pubis 20%
Ilium 40%
Ishium 40%
Where are the hip flexors located?
Anterior region of the LL
What plane does hip flexion occur within?
Sagittal plane
How many hip flexors are there? And can you name them?
5 Psoas major Iliacus Pectineus Rectus femoris Sartorius
Psoas Major - what’s the origin, insertion and what movement does it aid?
Origin: disks T12 - L5 (front of the lumbar transverse process)
Insertion: lesser trochanter
Aids hip flexion and internal rotation
Psoas Major - what’s the origin, insertion and what movement does it aid?
Origin: disks T12 - L5 (front of the lumbar transverse process)
Insertion: lesser trochanter
Aids hip flexion and internal rotation
Iliacus - what’s the origin, insertion and what movement does it aid?
Origin: iliac fossa
Insertion: lesser trocanter (with psoas major)
Aids hip flexion and internal rotation
Pectineus- what’s the origin, insertion and what movement does it aid?
Origin: superior pubic ramus, iliopubic eminence pubic tubercle (think pubis area)
Insertion: shaft of tibia
Aids hip flexion, hip adduction
Rectus femoris - what’s the origin, insertion and what movement does it aid?
Origin: straight head - anterior inferior iliac spine (lower than sartorius)
Reflected head - above the acetablum
Insertion: base of the patella
Aids hip flexion
Sartorius - what’s the origin, insertion and what movement does it aid?
Origin: anterior superior iliac spine
Insertion: shaft of tibia (Upper medial part)
Aids hip flexion
What plane does hip extension occur within?
Sagittal plane
How many hip extensors are there?
4
Where are the hip extensors located?
Posterior LL
Gluteus maximus - what’s the origin, insertion and what movement does it aid?
Origin: gluteal surface of the ilium, posterior sacrum, coccyx
Insertion: lesser trochanter (gluteal tuberosity of the femur) and IT band
Aids with hip extension, abduction and external rotation
Semi- tendinousus - what’s the origin, insertion and what movement does it aid?
Origin: ishial tuberosity
Insertion: shaft of tibia
Aids with hip extension
Semi membranous- what’s the origin, insertion and what movement does it aid?
Origin: ishial tuberosity
Insertion: tibia (medial tibial condyle)
Aids with hip extension
Biceps femoris - what’s the origin, insertion and what movement does it aid?
Origin: long head = ishial tuberosity
Short head = lower portion of the linear aspera
Insertion: fibula (head of fibula)
Aids with hip extension
In general where do the hamstrings originate?
Ishial tuberosity
How many hip abductors are there?
4
What plane does hip abduction occur within?
Coronal plane
Gluteus medius - what’s the origin, insertion and what movement does it aid?
Origin: gluteal surface of the ilium (and Co wring fascia)
Insertion: greater trocanter
Aids with hip abduction
Gluteus minimus - what’s the origin, insertion and what movement does it aid?
Origin: gluteal surface of the ilium
Insertion: greater trochanter
Aids with hip abduction
Tensor fascia lata - what’s the origin, insertion and what movement does it aid?
Origin: ASIS and iliac crest
Insertion: forms the IT band which attaches to the tibia (lateral condyle)
Aids with hip abduction
What plane does hip abduction occur within?
Coronal
How many hip abductors are there?
5
Can you name the hip abductors?
Adductor magnus Adductor longus Adductor brevis Pectineus Gracilis
In general where do the gluteus muscles originate?
Gluteal surface of the ilium
Adductor magnus - what’s the origin, insertion and what movement does it aid?
Origin: ishiopubic ramus and ishial tuberosity
Insertion: whole length of the linear aspera
Aids with hip adduction
Adductor longus - what’s the origin, insertion and what movement does it aid?
Origin:
Insertion:
Aids with hip adduction
