Summary
Ankle pain in young gymnasts may indicate an accessory navicular bone (AN). Magnetic Resonance Imaging (MRI) aids in diagnosing this condition, which is further classified by morphology.
Area of Science:
- Orthopedics
- Rheumatology
- Pediatric Sports Medicine
Background:
- A pediatric patient presented with ankle pain post-gymnastics, prompting orthopedic referral to rheumatology due to suspected underlying condition.
- The differential diagnosis included rheumatological etiologies for persistent ankle pain in young athletes.
Observation:
- Magnetic Resonance Imaging (MRI) was instrumental in identifying the cause of the patient's ankle pain.
- The imaging findings were consistent with an accessory navicular bone (AN).
Findings:
- Accessory navicular bone (AN) was diagnosed as the source of ankle pain in a young gymnast.
- The study discusses morphological classifications of accessory navicular bones.
- Various imaging modalities for diagnosing AN are presented.
Implications:
- Early and accurate diagnosis of accessory navicular bone (AN) is crucial for effective management in pediatric patients.
- Understanding AN morphology aids in tailoring treatment strategies.
- This case highlights the importance of advanced imaging in pediatric orthopedic and rheumatologic evaluations.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:28Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
