Glutes and hip joint Flashcards
(45 cards)
What is the intergluteal crest?
Buttcrack
What 2 ligaments form the greater sciatic foramen and lesser sciatic foramen
Sacrotuberous L. and sacrospinous L.
What is the origin and insertion for the sacrotuberous L.?
O: Anterior sacrum
I: Ischial tuberosity
What is the origin and insertion for the sacrospinous L.?
O: Anterior sacrum
I: Ischial spine
What exits the greater sciatic foramen?
Gluteal neurovascular bundle, piriformis m., sciatic nerve, posterior femoral cutaneous nerve, pudendal nerve and internal pudendal A., obturator internus/superior gemellus nerve
What enters the lesser sciatic foramen?
pudendal nerve and internal pudendal A., obturator internus/superior gemellus nerve
What exits the lesser sciatic foramen?
Obturator internus
What are the cutaneous nerves of the gluteal region?
Cluneal nerves - superior (L1-L3), middle (S1-S3)
Gluteal branches of posterior femoral cutaneous nerve (anterior rami)
What are the deep nerves of the gluteal region?
Sacral plexus branches (leave via greater sciatic foramen)
What does the superior gluteal nerve supply?
Gluteus medius, Gluteus minimus, Tenor fascia lata m.
Where does the superior gluteal nerve exit?
Superior to the piriformis m.
What does the inferior gluteal nerve supply?
Gluteus maximus
Where does the inferior gluteal nerve exit?
Inferior to the piriformis m.
Describe the largest nerve in the body
Sciatic nerve (L4-S3), eventually splits into tibial and common fibular nerve Does NOT innervate any gluteal region structures Exits inferior to piriformis m.
What are the main arteries in the gluteal region?
Superior and inferior gluteal arteries, pudendal artery (most medial, supplies genitalia)
Where does the superior gluteal artery exit?
Superior to the piriformis m. with the superior gluteal nerve
Where does the inferior gluteal artery exit?
Inferior to the piriformis m. with the inferior gluteal nerve
What does the superior gluteal artery supply?
Largest!
Gluteus maximus, medius, minimus, tenor fascia lata m.
What does the inferior gluteal artery supply?
Gluteus maximus, small lateral rotators, and superior hamstrings
What participates in the cruciate anastomosis?
Inferior gluteal artery, medial circumflex femoral artery, transverse branch of the lateral circumflex femoral artery, and the perforating arteries
Where should intragluteal injections be given?
Supero-lateral to avoid sciatic and other nerves
Gluteus maximus origin, insertion, action and innervation
O: Ilium, posterior sacrum and coccyx, sacrotuberous L.
I: Gluteal tuberosity, lateral tibial condyle via iliotibial band
A: Extend and laterally rotate thigh
Innervation: Inferior gluteal nerve
Gluteus medius origin, insertion, action and innervation
O: Ilium between anterior and posterior gluteal lines
I: Lateral side of greater trochanter
A: Abduct and medially rotate thigh
Innervation: Superior gluteal nerve
Gluteus minimus origin, insertion, action and innervation
O: Ilium between anterior and inferior gluteal lines
I: Anterior side of greater trochanter
A: Abduct and medially rotate thigh
Innervation: Superior gluteal nerve
