Hip joint Flashcards
What type of joint is the hip joint?
Synovial joint
Ball and socket type
What are the articulating surfaces of the hip joint?
Head of femur
Acetabulum of pelvis
What is the acetabular labrum?
Rim of fibrocartilage around the margin of the acetabulum
What is the purpose of the acetabular labrum?
Deepen the cavity of the acetabulum
so head of femur fits into it more
increases stability
What are the actebulum and head of femur covered with?
Articular hyaline cartilage
The hip joint ligaments can be divided into two groups - what are they?
Intracapsular ligaments - within joint capsule
Extracapsular ligaments - outside of joint capsule
What is the intracapsular ligament?
Ligament of head of femur
What does the ligament of head of femur attach to?
Acetabular fossa
Fovea of femur
What does the ligament of the head of femur enclose?
Artery to head of femur
The artery to head of femur branches off…?
Obturator artery
What are the extracapsular ligaments?
Iliofemoral ligament
Ischiofemoral ligament
Pubofemoral ligament
Where does the iliofemoral ligament attach?
Anterior inferior iliac spine
Intertrochanteric line of femur
What is the function of the iliofemoral ligament?
Prevent hyperextension of hip joint
Where does the ischiofemoral ligament attach?
Body of ischium
Greater trochanter of femur
What is the functon of the ischiofemoral ligament?
Prevent hyperextension of hip joint
