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
what is the sign of the buttock and what does it indicate?
noncapsular pattern with limited hip flexion with knee bent and straight, indicates a serious red flag
how does hamstring syndrome develop?
it is a result of nerve entrapment and irritation as the sciatic nerve courses around the ischial tuberosity and through a fibrous band projecting from the biceps femoris as it inserts upon the tuberosity
how can you dx hamstring syndrome?
test resisted knee flexion with ankle DF and hip flexion, then re-test in prone at a neutral hip angle and neutral foot. If positive on first part consider HS syndrome
what is the hip lag sign and what does it assess for?
patient is sidelying, leg brought into 10 degrees ext, abducted 20 degrees, 45 degrees of knee flexion. Let go, if they can’t hold indicates issues with hip abductors
what can cause sharp burning buttock pain?
entrapment of the pudendal nerve
what is a possible cause of pudendal nerve entrapment?
too narrow saddle on a bike
what is a possible source of deep, vague groin pain.
obturator nerve entrapment
what is a pincer impingement typically secondary to?
femoral retroversion
what motions will be painful in someone with an iliopsoas tendinopathy?
hip flexion and ER, will not have pain during hip adduction
