Insights
Legg-Calve-Perthes disease is childhood avascular necrosis of the hip. Treatment focuses on containing the femoral head to preserve joint function and range of motion.
Area of Science:
- Pediatric Orthopedics
- Pediatric Bone Diseases
- Pediatric Hip Disorders
Background:
- Legg-Calve-Perthes disease involves avascular necrosis of the proximal femoral epiphysis and growth plate.
- It typically affects children aged 4 to 8 years.
- The primary cause is likely vascular deficiency to the femoral epiphysis and growth plate.
Purpose of the Study:
- To outline the pathological stages of Legg-Calve-Perthes disease.
- To correlate radiologic findings with pathological stages.
- To discuss treatment principles and surgical options.
Main Methods:
- Review of pathological stages: necrosis, resorption, reossification, and remodeling.
- Correlation of radiographic findings with disease progression.
- Analysis of treatment strategies focusing on femoral head containment.
Main Results:
- Pathologic stages of Legg-Calve-Perthes disease are well-defined.
- Radiologic findings mirror the distinct pathological stages.
- Femoral head containment within the acetabulum is crucial for successful treatment outcomes.
Conclusions:
- Effective management of Legg-Calve-Perthes disease requires understanding its pathological progression.
- Treatment emphasizes maintaining femoral head containment and preserving range of motion.
- Surgical interventions like femoral osteotomy and shelf arthroplasty are considered.
Abstract:
Legg-Calve-Perthes disease reflects avascular necrosis of the proximal femoral epiphysis and growth plate in children age 4 to 8 years typically. The most likely etiology is vascular deficiency to the epiphysis and growth plate. The pathologic stages consist of necrosis, resorption, reossification, and remodeling. Radiologic findings reflect the pathologic stages. Containment of the femoral head with the acetabulum is the most important component of treatment, with preservation of range of motion also indicated in most patients. Surgical options for treatment include varus or valgus femoral osteotomy, innominate osteotomy, and shelf arthroplasty.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
