Week 5 - Intro to hip joint/axis Flashcards
What classification is the hip joint?
Synovial
What structures would you expect to see, that are common to all synovial joints?
Synovial membrane, synovial fluid, bursa, synovial cavity, supporting ligaments, articular capsule, bursa, fat pad
Why is knowing the axis of the hip joint important?
Understanding how the muscle acts to create movement at the joint.
Measurement - exactly where does the fulcrum of the goniometer go and allows accurate measurement of ROM.
Where is the axis of rotation for abduction at the hip?
Which plane and axis?
Femoral head
Coronal plane and sagittal axis
Where is the axis of rotation for extension?
Plane and axis?
Greater trochanter
Sagittal plane and coronal axis
Where is the axis of rotation for internal rotation at the hip?
Plane and axis?
Femoral head centre
Longitudinal axis and transverse plane
What are the anterior ligaments at the hip joint?
Iliofemoral ligament, pubofemoral ligament
Are the anterior ligaments of the hip tight or loose when you’re standing and why?
The ligaments are taut to prevent the trunk from extending beyond vertical
What is the posterior ligament of the hip joint called?
Ischiofemoral ligament
What is the role of the acetabular labrum?
It form’s suction of the femoral head into the acetabular hip joint.
Structures that help maintain stability in the hip joint?
Acetabular labrum, ligament of head of femur, 3 capsular ligaments and deep gluteal muscles
What is hip femoral torsion?
Also known as anteversion is when the femur twists inward. Retroversion is when there is less of an inward twist.
What is the normal degree of twist in adults?
15 degrees of anteversion
If someone was testing hip extension and the patient was feeling tightness at the front of the hip? Which ligaments may be tight in this position? And what part of the hip capsule is being assessed?
Iliofemoral and pubofemoral ligaments
And the anterior part of the hip capsule is being assessed?
