Exam 3: The Hip Flashcards
What are possible pathomechanics found in the hip region
decreased flexibility
asymmetrical leg length
hip muscle imbalances and their effects
What are possible causes of asymmetrical leg lengths
unilateral short leg
coxa valga and coxa vara
anteversion and retroversion
A person with a unilateral short leg will cause a pelvic ____ and sends the (thoracic/lumbar) spine into a side bend
tilt; lumbar
If a person has an anterior pelvic tilt, what muscles could be tight?
hip flexors and low back extensors
If a person has an anterior pelvic tilt, what muscles could be over stretched?
Abs and hamstrings
If a person has a posterior pelvic tilt, what muscle could be tight
abs and hamstrings
If a person has a posterior pelvic tilt, what muscles could be over stretched
hip flexors and low back extensors
Which muscle groups of the hip are important to function during gait
flexors, extensors, and abductors
Which muscle group is important to function during initial contact to limit hip extension
hip flexors
Why do the hip flexors need to function during gait
They are needed for IC to limit hip extension
Which muscle group is important to function during stance phase and initial contact to control the hip as we load
hip extensors
Why do the hip extensors need to function during gait
They are needed for initial contact and stance phase to control the hip as we load
Which muscle group is important to function during gait, especially during single limb stance to keep the pelvis neutral instead of dropping to one side
Hip abductors
Why do the hip abductors need to function during gait
They are needed in single limb stance to keep the pelvis neutral instead of dropping to one side
If a patient’s pelvis drops to onside during single limb stance instead of remaining in a neutral position (Trendelenburg’s) which muscle group is probably at fault
hip abductors
Which 3 nerves of the hip are subject to injury or entrapment
sciatic nerve
femoral nerve
obturator nerve
The sciatic nerve will be entrapped from the _____ muscle, causing pain to go down most of the leg
piriformis
Which nerve runs through the piriformis, often getting entrapped by this muscle and causing pain to run through the leg
sciatic
The femoral nerve runs (anterior/posterior) to the hip and is often injured from a femoral or pelvis fracture.
anterior
How is the femoral nerve commonly injured? Remember that it runs anterior to the hip
A femur or pelvis fracture
Which nerve runs anterior to the hip and can be injured if a femoral or pelvis fracture occurs
femoral
How is the obturator nerve usually injured?
In females that are giving birth
