[Prospects of using ultrasonic examination in Perthes disease]
Insights
Ultrasound offers early diagnosis and treatment monitoring for Perthes disease. This method accurately assesses hip joint structures and aids in classifying disease severity, reducing the need for X-rays.
Area of Science:
- Pediatric Orthopedics
- Diagnostic Imaging
Background:
- Perthes disease, or avascular necrosis of the femoral head, affects children.
- Accurate diagnosis and monitoring are crucial for effective management.
Purpose of the Study:
- To evaluate the utility of ultrasound in the early diagnosis and management monitoring of Perthes disease.
- To compare ultrasound findings with conventional radiography.
Main Methods:
- Fifty-two children (56 hips) aged 6-12 years with Perthes disease were studied.
- Ultrasound (5 MHz transducer) was used to assess synovial effusion, epiphysis, physis, and metaphysis.
- Ultrasound images were compared with anteroposterior (a-p) and Lauenstein radiographs.
Main Results:
- Ultrasound effectively assessed key hip joint structures in Perthes disease.
- A high correlation was found between ultrasound findings and radiographic assessments.
- Ultrasound facilitated classification according to Catterall's criteria and monitored treatment progress.
Conclusions:
- Ultrasound is a beneficial tool for early diagnosis and treatment monitoring in Perthes disease.
- It provides accurate assessment and aids in disease classification, reducing radiological exposure.
Abstract:
The paper indicates benefits from ultrasound early diagnostics and management monitoring in Perthes disease. Fifty-two children with 56 hips (35 boys and 17 girls) aged 6-12 years treated because of aseptic of the femoral head to Orthopaedic Department Lódź were included in this study. Five MHz transducer was positioned anteriorly along the anterior margin of the femoral neck in external rotation of the limb, neutral and internal one as well as in perpendicular fashion to the long axis of the neck. These four images were compared with conventional a-p and Lauenstein radiographs. Ultrasound allowed for assessment of the synovial effusion, shape of the epiphysis, configuration of the physis and the shape of metaphysis. High correlation between ultrasound examination and radiography was found. Ultrasonography allowed for assigning a hip to one of Catterall's type. It has also served well for monitoring of the treatment and reduced the number of radiological exposures.
