Clinical Orthopaedics and Related Research
|August 1, 1986
Summary
This study analyzed 165 Perthes disease cases, finding a 2.58:1 male-to-female ratio and frequent involvement of the right hip. Treatment planning for Perthes disease is complex due to various patient and disease factors.
Area of Science:
- Pediatric Orthopedics
- Pediatric Rheumatology
Background:
- Perthes disease (Legg-Calvé-Perthes disease) is a hip disorder affecting children.
- Understanding its epidemiology and clinical presentation is crucial for effective management.
Purpose of the Study:
- To analyze the clinical and epidemiological characteristics of Perthes disease in a large cohort.
- To identify factors influencing treatment planning and outcomes.
Main Methods:
- Retrospective review of 165 cases of Perthes disease over a 15-year period.
- Analysis of patient demographics, age at onset, sex ratio, affected side, disease severity (Catterall classification), and clinical presentation.
- Assessment of treatment challenges and outcomes.
Main Results:
- Mean age at onset: 9.89 years for boys, 8.71 years for girls. Male:female ratio of 2.58:1 with regional variations.
- Right hip more frequently affected in unilateral cases (92:63). 14% had fixed deformities; 10% had severe hip movement restriction.
- 70% classified as Catterall Group 3 or 4; 60% presented in the initial disease stage.
- A subset presented with tuberculosis-like features, resolving spontaneously with healed Perthes disease radiologically.
Conclusions:
- Perthes disease exhibits significant demographic and clinical heterogeneity.
- Treatment planning is complicated by late onset, higher proportion of girls, extensive epiphyseal involvement, and socioeconomic factors.
- Early diagnosis and appropriate management are essential for optimal outcomes in Perthes disease.
