SI Joint Clinical Presentations Flashcards
how are fx observed in the SIJ
fx observed vertically at ala
who tends to get a stress fx
athletes - due to increased training intensity (long distance runners)
older adults - diminished bone density
individuals with osteoporosis
symptoms of sacral stress fx
LBP/pain in butt - sometimes groin/LE
what can a sacral stress fx present like
cauda equina syndrome
physical exam of sacral stress fx
similar to HNP, spinal stenosis, tumors
antalgic gait
TTP areas
lumbar spine ROM more likely normal
how much motion occurs at SIJ
1-2 deg
structures that could be affected with mechanical SIJ disorders
capsule - a lot of the time anterior
ligaments
contractile units
mechanical SIJ disorders symptoms
pain in butt/groin/thigh
irritation by transitions, sitting, activities that require longer strides
phsyical exam of mechanical SIJ disorders
asymmetry with postural landmark exam
TTP affected SIJ stabilizers
provocation with procedures that stress affected SIJ ligament/capsule
laslett’s cluster
what is laslett’s cluster II
thigh thrust test
distraction test
sacral thrust
compression test
gaenslens test
when do you do laslett’s cluster II or van der wurff’s cluster
after u rule out lumbar involvement
what is van der wurff’s cluster
thigh thrust
distraction
patricks sign
compression test
gaenslens test
what is athletic pubalgia/osteitis pubis
chronic pain in pubic/inguinal region
weak lower abdominals & proximal hip adductors WITHOUT hernia
what is athletic pubalgia/osteitis pubis related to
hip pathologies like FAI
mechanism of athletic pubalgia/osteitis pubis
imbalance force transmission btw lumbosacral and hip which leads to pelvic instability, repetitive stress and inflammatory response
nerve entrapment in inguinal area
