Lecture 6 - Hip/Thigh Ax Flashcards
(48 cards)
Largest and most stable joints in the body
Hip joint
Type of joint for hip
Multiaxial ball-and-socket joint
T or F: Humerus is much more stable in the glenoid of the shoulder than the femur is in the acetabulum for the hip
FALSE, femur in acetabulum more stable
Role of the labrum (2)
Deepen and stabilize the joint
3 strong ligaments of the hip
Iliofemoral, ischiofemoral and pubofemoral
Under low loads, the joint surfaces are ___
Under heavy loads, they become ___ ; providing maximum surface contact
Incongruous
Congruous
Hip joint - resting position
Close packed position
Capsular pattern
30° flexion, 30° abduction, slight external rotation
Full extension, medial rotation, and abduction
Flexion -> abduction -> medial/internal rotation
The 3 ligaments limit __ and ___
Pubofemoral limits to ___
Extension and medial rotation
Abduction
Hx - Pain locations and sensations (3)
Anterior
Posterior
Clicking/snapping
Hx - anterior hip pain
Labral tears, impingement
Hx - posterior hip pain
Posterior labral tears, back/pelvis
Hx - clicking and snapping
Internal, external, intra-articular
When hip is affected, length of the step on affected side is ___ so that weight can be taken off leg ____
Shorter / quickly
In standing, the patient commonly has the hip slightly ___ if there is pain in the hip
flexed
What do you look for in observation from front, side and back? (6)
Posture
Symmetry of weight bearing
Balance
Limb positions
Leg length
Ease of movement
Examination (5)
Active movements
Passive movements
Resisted isometric movements
Functional assessment
Special tests
A/P/R for flexion (angle)
110-120°
A/P/R for extension(angle)
10-15°
A/P/R for abduction (angle)
30-50°
A/P/R for adduction (angle)
30°
A/P/R for lateral rotation (angle)
40-60°
A/P/R for medial rotation (angle)
30-40°
Normal end feel - Passive mvts = Flexion
Tissue approximation or tissue stretch
Normal end feel - Passive mvts = Extension
Tissue stretch
