hip Flashcards
what is present if the hip collodiaphyseal angle is less then 120 degrees?
coxa vara
what is the collodiaphyseal angle?
angle between femur and femoral head
what part of the labrum has decreased vascularization compared to the other regions
superior region
what is the coxafemoral joint?
hip joint
what supplies the sensory innervation of the anterior hip joint?
sensory branches of the femoral and obturator nerves
what supplies the sensory innervation of the posterior hip joint?
sacral plexus
where will anterior pubic symphesis pathology refer?
groin pain
where will posterior pubic sympthesis pathology refer?
genital pain
during movements such as the eccentric portion of the squat what motions occur at the femoral head?
flexion, abduction, IR
during movements such as the concentric portion of the squat what motions occur at the femoral head?
extend, adduct, ER
with patients between the ages of 4-10 what two conditions do you need to be aware of in the hip?
transient synovitis, legg-calves-perthes disease
what age do you need to be most aware of OCD?
15-25
what age do you need to be aware of Legg-Calves-Perthes?
4-10
what is Legg-Calves-Perthes?
AVN of the femoral head that impact the epiphyseal plate and causes issues with growth.
what is a CPR for hip OA (5 items)
squatting is painful, active hip flexion causes lateral hip pain, scour test with adduction causes pain, active hip extension causes pain, passive IR <25 degrees
what happens during an idiopathic synovial reaction at the hip?
basically frozen shoulder of the hip.
what are reliable predictors of ambulation ability following THA (2 factors)?
hip abductor strength, knee extension strength
what four things must someone be able to do after a THA to DC to home?
transfer from bed to standing, rise from a chair to standing, ambulate 100 feet, ascend and descend stairs independently
what patient profile do you need to be cautious with for transient synovitis?
under the age of 6, usually male, recent illness
at what age should you be concerned with a SCFE in boys and in girls?
13-15 in boys, 11-15 in girls
do SCFEs happen acutely or gradually?
both, acute presents with significant groin pain, gradually presents with limited IR and flexion
what is the Drehmann sign?
limited hip IR, increased hip ER, obligatory increased abduction and ER during passive flexion
what conditions may present with a positive Drehmann sign?
SCFE, LCPD
what is the clinical triad for a loose body in the joint?
non capsular pattern of limitation, pathological end feel, sharp shooting pain with leg giving way
