Child health Flashcards
What is perthes disease?
childhood orthopaedic condition characterized by idiopathic avascular necrosis of the femoral head
who does perthes disease occur in?
boys, aged 4-8
Aetiology of perthes disease?
HLA, genetic predis, vascular abn, trauma
staging of perthes disease?
Catteral staging
features of perthes disease
> Pain - most common.
limping - antalgic or trendeleburg
limited motion
leg length discrepency
what is trendeleburh due to?
abductor weakness
pain in perthes disease?
> pain localized to the hip, groin, or medial thigh.
The pain may be aggravated by activity and alleviated by rest.
In some cases, pain may be referred to the knee
radiological findings of perthes disease?
Findings include femoral head fragmentation, sclerosis, and flattening.
scans used for perthes?
> MRI - can detect early stages
bone scintigraphy
Cons management of perthes?
> pain management: analgesic, anti-inflammtories
physical therapy
orthotic devices
surgical management of perthes?
> Indications for surgery include persistent pain, progressive deformity, or failed conservative management
complications of perthes?

Acute hip pain associated with viral infection
Commonest cause of hip pain in children
FEATURES OF PERTHES DISEASE xr
x-ray: early changes include widening of joint space, later changes include decreased femoral head size/flattening

SUFE epi?
> head of femur slips along growth plate
more common in boys and obese children
presentation of SUFE?
The typical exam presentation is an adolescent, obese male undergoing agrowth spurt. There may be a history ofminor traumathat triggers the onset of symptoms. Suspect SUFE if the pain is disproportionate to the severity of the trauma.
Sx of SUFE?
> Hip, groin, thigh or knee pain
Restricted range of movement in the hip
Painful limp
SUFE examination?
When examining the patient, they will prefer to keep the hip inexternal rotation. They will have limited movement of the hip, particularlyrestricted internal rotation.
SUFE dx?
> XR
BTs normal
bone scan, CT, MRI
Mx of SUFE?
Surgery - returns femoral head to correct position
septic arthiritis is most common in?

Red flags that may indicate an underlying serious disease or condition in a child presenting with an acute limp include
Pain waking the child at night — may indicate malignancy.
Redness, swelling, or stiffness of the joint or limb — may indicate infection or inflammatory joint disease.
Weight loss, anorexia, fever, night sweats, or fatigue — may indicate malignancy, infection, or inflammation.
Unexplained rash or bruising — may indicate haematological or inflammatory joint disease, or child maltreatment.
Limp and stiffness worse in the morning — may indicate inflammatory joint disease.
Unable to bear weight or painful limitation of range of motion — may indicate trauma or infection.
Severe pain, anxiety, and agitation after a traumatic injury — may indicate neurovascular compromise or impending compartment syndrome.
A palpable mass — may indicate malignancy or infection
What is muscular dystrophy?
umbrella term for genetic conditions that cause gradual weakening and wasting of muscles.
Gowers sign?
Children withproximal muscle weaknessuse a specific technique to stand up from a lying position. This is calledGower’s sign.
there is a 5 year old boy presenting with vague symptoms of muscle weakness and the description is that you notice them using their hands on their legs to help them stand up, the answer is probably
Duchennes muscular dystrophy. They may ask “what is the underlying genetic inheritance of the most likely cause?” The answer is X-linked recessive.
