Some etiologic factors in Perthes' disease
Clinical Orthopaedics and Related Research
|July 1, 1980
Summary
Perthes' disease is not primarily genetic. Delayed skeletal maturation and environmental factors, including prenatal conditions, appear to increase risk in disadvantaged children.
Area of Science:
- Pediatrics
- Orthopedics
- Developmental Biology
Background:
- The etiology of Perthes' disease remains largely unknown.
- Research is increasingly focusing on environmental and developmental factors rather than genetics.
Purpose of the Study:
- To review genetic and environmental aspects of Perthes' disease.
- To explore potential predisposing factors and developmental sequences involved.
Main Methods:
- Literature review of genetic and environmental factors.
- Analysis of patient characteristics including birth history and socioeconomic status.
Main Results:
- No strong evidence for genetic factors in most Perthes' disease cases.
- Delayed skeletal maturation and retarded growth are present at diagnosis.
- Associated factors include breech birth, older parents, low income, and potentially prenatal environment.
Conclusions:
- Perthes' disease is likely a nongenetic developmental disorder with unknown etiology.
- Delayed maturation or intrauterine factors may predispose the femoral head to infarction.
- Undersized, disadvantaged children face a higher risk.
