Nokea
A 10-year-old boy has been diagnosed with Legg-Calvé Perthes disease. Which of the client's responses would indicate compliance during initial therapy?
- A. Drinking large amounts of milk
- B. Not bearing weight on affected extremity
- C. Walking short distances 3 times/day
- D. Putting self on weight reduction diet
Correct Answer: B
Rationale: This condition causes aseptic necrosis of the head of the femur in the acetabulum. Drinking large quantities of milk at this time cannot hasten recovery. The aim of treatment is to keep the head of the femur in the acetabulum. Nonweight-bearing is essential. Activity causes microfractures of the epiphysis. In addition to nonweight-bearing, clients are often placed on bedrest, which helps to reduce inflammation. Later, active motion is encouraged. Weight is not generally an issue with this disease. Slipped femoral capital epiphysis, which is most frequently observed in obese pubescent children, usually requires a weight reduction diet.
