Legg-Calvé-Perthes Disease
What Went Wrong?
Legg-Calvé-Perthes disease is a necrosis of the femoral head that occurs in
children between 2 and 12 years of age caused by a decreased blood supply
to the femoral head. This disease is self-limiting, and the child will fully
recover after the disease has run its course.
There are three stages of Legg-Calvé-Perthes disease:
Avascular: Blood supply to the head of the femur is interrupted within
1 year.
Revascularization: Creeping substitution occurs where connective and
vascular tissue enter the necrotic bone causing live noncalcified bone to
replace the necrotic tissue.
Healing: The bone ossifies over 3 years.
Signs and Symptoms
Painless limp
Pin in the knee during activity
Pain in the groin
Pain in the anterior thigh
Test Results
Radiograph: Shows decreased bone mass, ossification centers, and possibly
subchondral fracture.
Treatment
Legg-Calvé-Perthes disease is self-limiting.
Physical therapy to restore range of motion.
Administer analgesic to reduce pain.
Nursing Interventions
Perform range-of-motion activities to maintain normal motion of the joint.
Teach the patient how to use crutches.
Explain to the parents and the patient that the disease is self-limiting and
that the patient will fully recover once the disease has run its course.
Talipes (Clubfoot)
What Went Wrong?
A clubfoot is a congenital deformity that occurs in utero due to adverse effects
of medication, infection, trauma, or genetic trait resulting in contracture of
soft tissue and abnormal development of a joint and muscles.
Signs and Symptoms
Usually position or forming of one or both feet
