what are current s/s of hip pathology?
tasks that are challenging
snapping, catching, locking
magnitude of pain
location of pain (C-sign)
referral patterns
t/f: leg length discrepancies always have a great impact on the treatment and pathology
false
what is the clinical presentation of pediatric hip pathology?
assymetry of the thighs or gluteal folds
limitation of hip abd
unequal femoral length
abnormal gait pattern
(+) Ortolani test

t/f: the success of the Pavlik harness decreased in pts older than 4 months
true
what does a Pavlik harness do?
holds the hip at 90-100 degrees of flexion
what are some long term effects of DDH?
gait dysfxn
hip pain
DJD of hip
early onset THA
what is avascular necrosis (Legg-Calve-Perthes Disease)?
damage to vascular supply that may occur at birth
trauma resulting in ischemia
what % of avascular necrosis progresses to lead to collapse of the femoral head?
70-80%
what population is avascular necrosis most common in?
boys aged 3-13 yo (average 5-7 yo)
what are the s/s of avascular necrosis (Legg-Calve-Perthes disease)?
pain in the groin, buttock, proximal thigh
pain exacerbated by weight bearing
decreased ROM
antalgic gait
what are some interventions for avascular necrosis (Legg-Calve-Perthes disease)?
emphasis on containment of the femoral head and avoiding collapse
Scottish Rite brace to hold the femur in abd w/the ability to flex
surgical intervention (hip resurfacing vs THA)
what is slipped capital femoral epiphysis (SCFE)?
the femoral head slips down and back off the femoral neck
what is the initial symptom of 45% of pts with a SCFE?
knee or lower thigh pain
t/f: fx screening of a SCFE can manifest as a compression or tension rxn
true
if a pt with a SCFE has a compression rxn, what should be done?
reduce WB
therapy
if a pt with a SCFE has a tension rxn, what should be done?
NWB often progresses to displacement and needs ORIF
what is the stress fx intervention for SCFE?
nutrition
metabolic panal

aerobic conditioning
what is the purpose of the patella-pubic percussion test?
to assess for osseous pathology
what is the position for the patella-pubic percussion test?
supine w/the stethoscope on the pubic symphysis
what is the technique of the patella-pubic percussion test?
percuss or vibrate tuning fork on the patella and compare BL to hear for difference in sound
what would be a positive result of the patella-pubic percussion test?
decreased sound transmission when compared BL
what are the stats for the patella-pubic percussion test?
sensitivity=excellent
specificity=high-excellent
t/f: you should always ask WHERE the pain is when doing special tests
true
what is the purpose of the sign of the buttocks?
to assess for hip pathology, neoplasm, or abscess

what is the technique for the sign of the buttocks?
performs passive SLR, note the angle of hip flexion that symptoms occur in
flex the hip and knee and compare the angle of hip flexion that symptoms occur at w/the SLR angle
what is a (+) test for the sign of the buttocks?
