Chapter 24 - Hip Flashcards
After completing this chapter, you should be able to do the following: - Discuss how anteversion and retroversion change LE mechanics - Explain the mechanical factors involved in a gait with hip abductor weakness, and explain how a can or single crutch assists in normal gait - Identify a joint mobilization technique for the hip and explain its benefit - Identify a flexibility exercise and a strengthening exercise for the hip - Identify a proprioception exercise for the hip and indicate its progr
The hip socket is called the ____________
acetabulum
What does anterolateral mean?
Anterior - in front of body; lateral - away from the midline
What does inferior mean?
Below
What kind of position is the hip socket? And what is the hip socket called again?
inferior and antelateral; acetabulum
What angle is the femoral neck?
125 degrees
What is it called if the femoral neck is at an angle greater than 125 degrees? And what’s wrong with it?
Coxa valga - causes increased pressure into the joint - increased risk of osteoarthritis
What is it called if the femoral neck is less than 125 degrees? What’s wrong with that?
coxa vara - increased stress of the femoral neck, more susceptible to fractures
If the angle of the femoral neck to the femur is greater than 15 degrees what is this condition called?
anteversion
If the femoral neck’s position is less than 15 degrees to the femur’s long axis, what is this called?
retroversion
What does anteversion and retroversion do?
They alter the knee alignment and change the forces acting throughout the entire lower extremity
When can nerve irritations occur in terms of the hip?
When the soft tissues surrounding the hip impinge on a nerve
What muscle does the sciatic nerve run beneath and sometimes through before it travels along the posterior thigh?
piriformis
Which muscles play a very important role in pelvic stability?
hip extensors and abductors
If hips are weak
other parts of the chain must make up for the hip’s inability to provide the needed LE forces.
The hips must be the platform from which the _______ functions
pelvis
The pelvis is the platform from which the ________ functions
scapula
Scapula is the platform from which the __________ functions
shoulder complex
Pelvis movement has a direct influence on hip movement because the hip joint’s socket is comprised of _________
pelvic bones
When a cane or one crutch is used ton the side opposite the weakness, a(n) ________ force is transmitted through ____________ to counterbalance the __________ gravitational force on the same side
upward; the appliance; downward
If a patient cannot ambulate normally, then what?
He or she must use assistive devices until normal ambulation is possible without them
An abnormal gait may result from ______, _________, or ___________.
pain, inadequate muscle control, or apprehension
If the abnormal gait continues, then what could happen?
stresses will increase on the hip, back, or other LE segments resulting in further injury
Why did Adelle cross the road?
to get unto the other side!
T or F: As the problem causing the need for crutches or other assistive devices resolves, the patient is weaned off of them.
True
