13- HIP Flashcards
What are the parts of the hip bone?
Ilium
Ischium
pubis
What actions can we do with the hip?
Flexion/Extension
Abduction/adduction
Medial/Lateral rotation
Circumduction
Which muscles flex the hip?
Psoas major
Illiacus
Minor flexors: Rectus femoris, sartorious
Psoas Major
Origin: Transverse processes of T12- L5 and the lateral aspects of the discs between them
Insertion: Lesser trochanter of the femur
Nerve: Lumbar plexus (L1- L3)
Action: Flexes the hip joint
Origin: Upper 2/3 of the iliac fossa
Insertion: Base of the lesser trochanter of the femur
Nerve: Femoral Nerve
Action: Flexes and laterally rotates the hip joint
Illiacus
What are the hip extensors?
Gluteus Maximus
Hamstrings- Biceps femoris, Semitendiosis, semimembranosis
Minor hip extensors-Gluteus Medius, adductor magnus
Origin: Gluteal surface of the ilium
Insertion: Gluteal tuberosity of the femur and iliotbial band
Nerve: Inferior gluteal nerve
Action: External rotation and extension of the hip joint.Supports the extended knee through the IT band, and abduction of the hip
Gluteus maximus
Biceps Femoris
Origin: (LH) ischial tuberosity. (SH) linea aspera of the femur
Insertion: Head of the fibula
Innervation: (LH) tibial n. (sh) common fibula n.
Action: Both heads: Flex knee,(LH) extends hip
Semitendinosus
Origin: Ischial Tuberosity
Insertion: Pes Anserinus (tibia)
Innervation: Sciatic N (tibial)
Action: Flex knee, extends hip
Semimembranosus
Origin: Ischial tuberosity
Insertion: Medial Condyle of the tibia
Innervation: Sciatic N(tibial)
Action: Flex knee, extends hip
States the tendons of the pes anserinus
Sartorius
Semitendinosus
Gracilis
Hip adductors
- adductor magnus
- adductor longus
- adductor brevis
- pectineus
- gracilis
Origin: Ischiopubic ramus
Insertion: pes anserinus
Innervation: Obturator n.
Action: Flexes,medially rotates and adducts the hip
Gracilis
Adductor Magnus
Origin: Pubis,ischial tuberosity
Insertion: linea aspera and adductor tubercle of the femur
Innervation: Obturator n (adductor part) and sciatic n (hamstring part)
action: extends hip, flexes hip, adducts hip
Adductor longus
Origin: Pubic body, just below crest
Insertion: Middle 1/3 of the linea aspera
Innervation: Obturator nerve
Action: adducts hip
Adductor brevis
Origin: Anterior surface of the inferior ramus of the body of the pubis
Insertion: Lesser trochanter and linea aspera
Innervation:obturator nerve
Action: Adducts hip (some flexion)
Pectineus
Origin: Pectineal line of the pubic bone
Insertion: Pectineal line of the femur
Innervation: Obturator nerve
Action: Flexes and adducts hip assists with medial rotation
Hip abductors
Gluteus Maximus
Gluteus Medius
Gluteus Minimus
Tensor Fascia Lata
Origin: Gluteal surface of the ilium, lumbar fascia, sacrum
Insertion: Gluteal tuberosity of the femur and iliotbial band
Nerve: Inferior Gluteal Nerve
Action: External rotation and extension of the hip joint. Supports the extended knee through the IT band, and abduction of the hip
Gluteus Maximus
