Insights
This study describes normal Achilles tendon and calcaneal apophysis sonographic features in children. These findings provide a reference for assessing pediatric heel pathologies using high-frequency ultrasound.
Area of Science:
- Pediatric Radiology
- Musculoskeletal Ultrasound
- Pediatric Orthopedics
Background:
- The pediatric heel, particularly the Achilles tendon insertion and calcaneal apophysis, is susceptible to pathologies during growth.
- Establishing normative sonographic data is crucial for accurate diagnosis and management of heel pain in children.
Purpose of the Study:
- To characterize age-related sonographic features of the Achilles tendon and calcaneal apophysis in children.
- To provide a sonographic reference for evaluating heel pathologies during pediatric growth.
- To assess the bone-cartilage interface at the calcaneal tuberosity using ultrasound.
Main Methods:
- High-frequency gray-scale and color Doppler sonography were used to examine 100 children aged 2 months to 18 years.
- Longitudinal and transverse imaging planes were employed to visualize the calcaneal apophysis and Achilles tendon insertion.
- Measurements of apophyseal cartilage and Achilles tendon thickness were performed, alongside evaluation of the bone-cartilage interface.
Main Results:
- In young children (2 months to 3 years), calcaneal apophysis cartilage was anechoic with scattered echoes, often showing vascularity on color Doppler (76%).
- A wavy bone-cartilage interface was observed in 60% of children aged 4-6 years.
- Sonographic features varied with age, reflecting normal developmental changes in the pediatric heel.
Conclusions:
- High-frequency sonography provides reliable assessment of the bone-cartilage interface and Achilles tendon insertion in children.
- The described sonographic features of the normal pediatric heel serve as a valuable reference for diagnosing pathologies.
- This study enhances the diagnostic capabilities for heel conditions in the pediatric population through standardized ultrasound assessment.
Purpose:
The aim of this study was to describe typical age-related sonographic features of the Achilles tendon and calcaneal apophysis in children, providing a reference for the assessment of heel pathologies during the growth period.
Methods:
The calcaneal apophysis and Achilles tendon insertion of 100 children 2 months to 18 years old were examined by high-frequency gray-scale and color Doppler sonography along both the longitudinal and transverse planes. The thicknesses of the apophyseal cartilage at the calcaneal tuberosity and of the Achilles tendon were measured. Also, the sonographic appearance of the bone-cartilage interface was studied.
Results:
In children 2 months to 3 years old, the cartilage of the calcaneal tuberosity apophysis was anechoic, with small scattered echoes. In 19 of these 25 children (76%), the echogenic areas contained at least 1 small vessel, visualized on color Doppler sonography. In 15 of 25 children (60%) 4-6 years old, a wavy interface was noted at the junction of the calcaneus and the apophyseal cartilage.
Conclusions:
High-frequency sonography can yield reliable information about the bone-cartilage interface and the Achilles tendon insertion site at the calcaneal tuberosity in children. The sonographic features of the normal heel described here may contribute to improved assessment of pathologies in this anatomic region.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
