Lecture 028: Lower Limb II - Muscles of the Medial and Posterior Thigh
Objectives
● Briefly review the relevant bony landmarks of the pelvic girdle, femur, tibia, and fibula
● Describe the three gluteal muscles
● Describe the five adductor muscles of the medial compartment of the thigh
● Describe the three hamstring muscles of the posterior compartment of the thigh
● Diagnose nerve damage and/or muscle weakness based on clinical symptoms
Review
● Ramus
● Posterior gluteal line
○ Upper ridge on the ilim
● Anterior gluteal line
● Inferior gluteal line
● Ischial tuberosity
● Pubic bone
Review of the Femur
● Greater trochanter
● Lesser trochanter
● Gluteal tuberosity
● Pectineal line
● Linea Aspera
○ Back of the middle of the femur
● Media and lateral supracondylar line
Review of the Tibia
● Lateral tibial condyle
● Medial tibial condyle
● Medial Aspect of the Proximal tibia
Review of the Fibular
● Head of the Fibula
Gluteal Muscles
●Gluteus Maximus
○ Superficial
○ Largest muscle in the body
○Origin:
■ Dorsal ilium, sam and coccyx
■ Crosses the back of the hip joint
○Insertion:

■ Gluteal tuberosity of the femur , iliotibial tract
○Innervation:
■ Inferior gluteal nerve
○Actions:
■ WExtension, abduction and lateral rotation of the hips
●Gluteus Medius
○ Deeper, and superior to the gluteus maximus
○Origin:
■ Between the anterior and posterior gluteal lines
○Insertion:
■ Greater trochanter of the femur
○Innervation:
■ Superior gluteal nerve
○Actions:
■ Abduction (out) and medial rotation of the hips
●Gluteus Minimus
○ Deepest
○Origin:
■ Between the anterior and inferior gluteal lines
○Insertion:
■ Greater trochanter femur
○Innervations:
■ Super gluteal nerve
○Actions
■ Abduction and medial rotation of the hip
■ Steadies the pelvis during walking
●Posterior Pelvic Tilt
○ Gluteus medius and minimus
●Trendelenburg gait is caused by a neuromuscular weakness of which muscle(s)?
○ The gluteus medius and minimus
■ These muscles stabilizes the pelvis when you are walking
Building a Well-Rounded Booty
● Preactivation movements to warm up
○ Light weight, high reps
● Compound exercises (1 or 2)
○ Hip thrust
○ Glute hamstring raise
○ Squats (wider legs, toes slightly laterally rotated)
○ Lunges
● Isolation Exercises (3 -4)
○ Machine hip abduction
○ One legged cable kickbacks
● Target the glutes 3-4 times per week

Document Summary
Lecture 028: lower limb ii - muscles of the medial and posterior thigh. Briefly review the relevant bony landmarks of the pelvic girdle, femur, tibia, and fibula. Describe the five adductor muscles of the medial compartment of the thigh. Describe the three hamstring muscles of the posterior compartment of the thigh. Diagnose nerve damage and/or muscle weakness based on clinical symptoms. Back of the middle of the femur. Crosses the back of the hip joint. Gluteal tuberosity of the femur , iliotibial tract. Wextension, abduction and lateral rotation of the hips. Deeper, and superior to the gluteus maximus. Between the anterior and posterior gluteal lines. Abduction (out) and medial rotation of the hips. Between the anterior and inferior gluteal lines. Abduction and medial rotation of the hip. These muscles stabilizes the pelvis when you are walking. Squats (wider legs, toes slightly laterally rotated) Target the glutes 3-4 times per week. Body of pubis and inferior pubic ramus.
