Insights
Transient synovitis of the hip is common in children. Ultrasound is a sensitive and accurate diagnostic tool for identifying hip exudate, aiding in prompt treatment.
Area of Science:
- Pediatric Orthopedics
- Diagnostic Imaging
Background:
- Transient synovitis of the hip is the leading cause of limping in children.
- Accurate diagnosis is crucial for effective management.
Purpose of the Study:
- To evaluate the efficacy of real-time hip arthrosonography in diagnosing transient synovitis in pediatric patients.
- To assess the diagnostic accuracy of ultrasound compared to other methods.
Main Methods:
- Fifty-eight children diagnosed with hip transient synovitis between 1989-1991 were analyzed.
- Ultrasound examinations were performed using Siemens and Kretz scanners with 5 MHz transducers.
- Measurements of the distance between the femoral neck and joint capsule were taken using Adam's morphometric procedure.
Main Results:
- Ultrasound confirmed joint effusion in all 58 cases.
- Pathological measurements ranged from 7 mm to 14 mm, significantly exceeding normal values (2 mm to 4 mm).
- Real-time arthrosonography demonstrated high sensitivity and accuracy.
Conclusions:
- Real-time hip arthrosonography is a highly sensitive and accurate diagnostic procedure for transient synovitis in children.
- Ultrasound offers superior diagnostic value compared to alternative methods for this condition.
Abstract:
The most common cause of a limp in childhood is transitory synovitis of the hip. At the Paediatric Surgery Clinic in Novi Sad, in the period from 1989 to 1991, 58 children were treated for hip transitory synovitis and the diagnosis was confirmed by ultrasonic finding of the exudate in the joint. The ultrasonic investigation of the hips was performed by using Siemens and Kretz scanners equipped with 5 MHz linear or sector transducers. The approach to the hip was frontal and the lower extremity has been in the neutral position. The distance between the femoral neck and the joint capsule was verified according to the Adam's morphometric procedure. The measured pathological values were from 7 mm to 14 mm (normal values are from 2 mm to 4 mm). In the routine transitory synovitis diagnosis, real-time arthrosonography of the hip shows high sensitivity, accuracy and selective values compared to other diagnostic procedures.
