Musculoskeletal Structure of the Hip Flashcards
What are the Three Major Joints in the Hip?
Coxofemroal Joint
Sacroiliac Joint
Pubic Symphysis
What makes the Coxofemoral Joint?
the head of the femur and the acetabulum of the hip
What bones make up the Acetabulum?
Ilium
Ischium
Pubis
“cuplike area”
What ligament connects the head of the femur to the acetabulum?
Capitis Femoris Ligament
What ligament connects the ilium to the femur?
Iliofemoral Ligament
What is the shape of the Iliofemoral Ligament?
Y-shaped
What does the Iliofemoral Ligament resist?
extension, internal rotation, and some external rotation
What action do hip ligaments resist?
flexion
What does the Ischiofemoral Ligament resist?
adduction and internal rotation
Where does the Biceps Femoris Short Head attach?
the medial and lateral lip of the femur
What is the normal angle of the Femoral Neck?
125 degrees
What is the Femoral Neck?
part of the femur that holds it away from the pelvis
What is the result of Coxa Vara?
whenever the Femoral Neck angle is less than 125 degrees; puts more load on the neck rather than the head
What is related with Coxa Vara?
related with Genu Valgus
What is the result of Coxa Valga?
whenever the Femoral Neck angle is more than 125 degrees; puts more load on the femoral head rather than the femoral neck
What is related with Coxa Valga?
Genu Varum
What is the Angle of Anteversion?
in the transverse plane, the angle of the femoral neck
What is Excessive Anteversion?
whenever the leg rotates inward in order to keep the head of the femur in the acetabulum
What is Retroversion?
whenever the angle of ante version is reversed; so foot rotates externally
What are the Primary Hip Flexors?
Psoas Major
Iliacus
What are the Assistant Hip Flexors?
Tensor Fascia Latea
Sartorius
Rectus Femoris
What are the Hip Extensors?
Gluteus Maximus
Hamstrings
What are the Hip Adductors?
Pectineus
Adductor Brevis
Adductor Longus
Adductor Magnus
What is the Assistant Hip Adductor?
Gracilis
