Perthes' disease. A study of radiological features

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Radiology

Background:

• Perthes disease is a hip condition affecting children.
• Radiographic classification helps understand disease progression.
• Identifying prognostic factors is crucial for treatment.

Purpose of the Study:

• To classify unilateral Perthes disease based on radiographic appearance.
• To compare clinical and radiological outcomes between different disease types.
• To determine if fragmentation impacts healing results.

Main Methods:

• Retrospective analysis of radiographs from 68 patients with unilateral Perthes disease.
• Classification into 'fragmenting' and 'non-fragmenting' types.
• Assessment of radiological healing quotients (epiphyseal, acetabular, acetabulum-head, comprehensive).

Main Results:

• No significant differences in age at diagnosis, symptom duration, or disease duration between the two types.
• Patients with the 'fragmenting' type exhibited significantly worse radiological outcomes at healing.
• Key quotients including epiphyseal, acetabular, and comprehensive scores were poorer in the fragmenting group.

Conclusions:

• Radiographic fragmentation is a significant indicator of poorer healing outcomes in Perthes disease.
• The 'fragmenting' classification identifies a subgroup with a worse prognosis.
• Further research may explore tailored treatment strategies for fragmenting Perthes disease.
