FINAL EXAM Flashcards
(69 cards)
the acetabulum is formed by fusion of which 3 bones?
ilium
ischium
pubis
= innominate bone/ pelvis
function of the acetabular labrum
holds femoral head in acetabulum
increases surface area
acts as shock absorber
stabilizes hip during lat.R while also preventing anterior translation
the hip is supported by which 3 ligaments?
iliofemoral
ischiofemoral
pubofemoral
= limit int.R
aka Y ligament of Bigelow
one of the strongest ligaments in body, prevents excessive ext., plays role in stabilizing body & maintaining upright posture at hip while also limiting anterior translation
iliofemoral ligament
weakest of the 3 strong ligaments of the hip, winds tightly on extension, helping to stabilize the hip
ischiofemoral ligament
ligament of the hip that is intra-articular, supports vascular supply to the femoral head and acts as a hip stabilizer
ligamentum teres
resting position of the hip
30° flexion, 30° ABD , slight ext.R
closed packed position: full extension, int.R, ABD
capsular pattern: flexion, ABD, int.R
most common mechanism of injury for a hip dislocation is a car accident where the femur is forced…
posteriorly
snapping in the hip can be caused by what?
-tight ITB, snapping over iliopectineal eminence
-slipping of iliopsoas over lesser trochanter of femur
-acetabular labral tear
borders of the femoral triangle
inguinal ligament
adductor longus
sartorius
osteoarthritis can also be referred to as what?
degenerative joint disease (DJD)
= most common disease process affecting the hip
where are cartilaginous changes first seen with normal aging for OA of the hip?
nonarticular areas of cartilage
DJD: seen first in areas of cartilage that undergo most frequent contact (weight bearing)
predisposing factors for OA or DJD of the hip
leg length discrepancy
capsular tightness
loss of extensibility
with weight bearing of the hip, where is pain usually felt?
groin or trochanteric pain
observations with OA/ DJD
-difficulty rising from sitting
-antalgic/ trendelenbrug gait
-trunk lurch toward affected side if limb short
-difficulty removing shoes, socks, slacks
which special test is performed in order to assess for Osteoarthritis or capsulitis?
hip scour
when is pain noticed for OA of the hip and at what age do symptoms occur?
at end of day
middle-aged/ older, insidious onset
with progressive capsular tightness in the hip, what does the client notice they have difficulty with at first?
difficulty squatting
which bursitis can mimic sciatic pain & can present with an antalgic gait with the patient leaning towards affected side?
ischial
contributing factors for bursitis
mm imbalances
poor biomechanics
postural dysfunctions
lack of flexibility
when is pain usually worse with trochanteric bursitis?
climbing stairs & getting out of car
P at lateral hip
pain at the anterior hip and may radiate down the anterior leg due to pressure on the femoral nerve
iliopectineal bursa
with an ITB contracture, what bursa can become inflamed?
trochanteric
causes of ITB contracture
-activities that place knee & hip in flexion (cycling, horseback riding, prolonged sitting)
-postural imbalances (anterior pelvic tilt)
-prolonged wheelchair use/ bedrest
