Legg-Calvé-Perthes disease (LCPD) affects children, causing avascular necrosis of the femur head. Surgery is recommended for older children with extensive necrosis, while younger children benefit from symptomatic treatment.
Area of Science:
- Pediatric Orthopedics
- Avascular Necrosis Research
- Skeletal Dysplasia Studies
Background:
- Legg-Calvé-Perthes disease (LCPD) involves avascular necrosis of the femoral head.
- Epidemiology, etiology, treatment, and prognosis are key aspects of LCPD.
Purpose of the Study:
- To review the epidemiology, causes, treatment, and prognostic factors of Legg-Calvé-Perthes disease.
- To analyze a Norwegian countrywide study on LCPD management.
Main Methods:
- Non-systematic literature review.
- Analysis of clinical practice.
- Inclusion of a Norwegian nationwide study on pediatric LCPD.
Main Results:
- LCPD incidence varies globally.
- Older age at diagnosis and >50% femoral head necrosis correlate with poorer prognosis.
- Varus femoral osteotomy showed superior outcomes in older children with extensive necrosis compared to physiotherapy or orthosis.
Conclusions:
- Surgical intervention (varus femoral osteotomy) is advised for children aged six years or older with >50% femoral head necrosis.
- Symptomatic treatment is recommended for younger children or those with <50% necrosis.
- Abduction orthosis is not indicated for LCPD treatment.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
