HA Exam I | Questions| With Correct Answers.
What are the muscles in the gluteal compartment
- Glute max
- Glute min
- Glute med
- TFL
- Piriformis
- Obturator internus
- Superior gemellus
- Inferior gemellus
- Quad fem
Gluteal Bursa
- Trochanteric bursa
- Ischial bursa
- Gluteofemoral bursa
Trochanteric bursa- separates superior fibers of glute max from greater trochanter
Ischial bursa- separates the inferior part of glute max from the ischial tuberosity
Gluteofemoral bursa- separates the IT band from the proximal attachment of the
vastus lateralis
Proximal Attachment Gluteus Maximus
Ilium posterior to posterior gluteal line; dorsal surface of sacrum and coccyx;
sacrotuberous lig
Distal Attachment Gluteus Maximus
Most fibers (superficial ¾) end in iliotibial tract (band); some fibers insert on the gluteal
tuberosity (deep ¼)
Intervation Gluteus Maximus
Inferior gluteal nerve (L5 - S2)
Arterial Supply Gluteus Maximus
,- Inferior gluteal artery
- Superior gluteal artery
Main Action Gluteus Maximus
- Extends thigh (especially from flexed position, e.g., sitto-stand, squat, stairs, walking
uphill, running)
- Assists lateral (aka, external) rotation of thigh
Proximal Attachment Gluteus Medius
External surface of ilium between anterior and posterior gluteal lines
Distal Attachment Gluteus Medius
Lateral surface of greater trochanter of femur
Innervation Gluteus Medius
Superior gluteal nerve (L5, S1)
Arterial Supply Gluteus Medius
Superior gluteal artery
Main Action Gluteus Medius
- Abduct and medially (aka, internally) rotate thigh
- Keep pelvis level during ipsilateral limb weight bearing
- Advance contralateral pelvis and limb side during its swing phase of gait
Proximal attachment Gluteus Minimus
External surface of ilium between anterior and inferior gluteal lines
Distal Attachment Gluteus Minimus
Anterior surface of greater trochanter of femur
Innervation Gluteus Minimus
Superior gluteal nerve (L5, S1)
Arterial Supply Gluteus Minimus
Superior gluteal artery
Main Action Gluteus Minimus
- Abduct and medially (aka, internally) rotate thigh
- Keep pelvis level during ipsilateral limb weight bearing
- Advance contralateral pelvis and limb side during its swing phase of gait
Proximal Attachment Tensor Fasciae Latae
, - Anterior superior iliac spine (ASIS)
- Anterior part of iliac crest
Distal Attachment Tensor Fasciae Latae
Iliotibial tract, which attaches to lateral condyle of tibia at the anterolateral tubercle of
the tibia (aka. Gerdy's tubercle)
Innervation Tensor Fasciae Latae
Superior gluteal nerve (L5, S1)
Arterial Supply Tensor Fasciae Latae
Ascending branch of Lateral Circumflex Femoral (LCF) artery
Main Action Tensor Fasciae Latae
- Assist gluteal muscles to abduct and medially rotate the thigh; keep pelvis level during
stance and weight bearing
- Assist with stabilization of both the hip and knee
REMEMBER:
- Patched
- Goods
- Often
- Go
- (On)
- Quilts
- Piriformis
- Gemellus Superior
- Obturator Internus
- Gemellus Inferior
- (Obturator Externus)
- Quadratus Femoris
Proximal Attachment Piriformis
Anterior surface of sacrum; sacrotuberous ligament
Distal Attachment Piriformis
Superior border of greater trochanter of femur
Innervation Piriformis
