bilateral long leg or 1 + 1 1/2 hip spica cast
legg calve perthes disease - who is affected?
male 5:1 female
primary school age
perthes presentation
15% bilateral, short, limp, pain on exercise, stiff hip joint
Phases of LCP
avascular necrosis
fragmentation - revascularisation and pain
reossification - bony healing
residual deformity
differential of unilateral LCP
septic hip
JIA
SCFE
lymphoma

hypothyroid
sickle
epiphyseal dysplasia
Treating LCP
maintain hip motion analgesia restrict painful activities supervised neglect containment
SCFE - who affected?
boys, teenage, 1-10/100 000
how to fix stable vs unstable SCFE
stable = fix in situ unstable = serendipitous reduction
detecting SCFE
pain in hip or knee
ER posture and gait
decreased internal rotation
plain x-rays (lateral)
classifying SCFE
femoral neck width
mild = <1/3
moderate = 1/3-1/2
severe = >1/2
What zone does displacement occur in SCFE?
hypertrophy zone
Metaphysis moves what way in SCFE?
anterior and proximal
treating SCFE
surgery and screws to fix in place
