Summary
Os vesalianum, a rare accessory foot bone, caused lateral foot pain in an 18-year-old male. SPECT/CT bone scans revealed characteristic uptakes in the ossicles of both fifth metatarsal bones.
Area of Science:
- Orthopedics
- Radiology
- Anatomy
Background:
- Accessory ossicles in the foot are uncommon anatomical variations.
- Os vesalianum is a rare accessory ossicle located at the base of the fifth metatarsal.
Observation:
- An 18-year-old male presented with lateral foot pain.
- Radiographs revealed an abnormal ossicle articulating with the fifth metatarsal and cuboid bones.
- Bone scintigraphy and SPECT/CT showed increased uptake in bilateral fifth metatarsal ossicles.
Findings:
- CT confirmed well-corticated margins of the ossicle and adjacent bones.
- The findings were consistent with a diagnosis of os vesalianum.
- This case highlights the utility of SPECT/CT in evaluating accessory ossicles.
Implications:
- Accurate diagnosis of os vesalianum is crucial for appropriate management of foot pain.
- SPECT/CT imaging provides detailed functional and anatomical information for rare bone variations.
- Understanding these anatomical variations aids in differential diagnosis of lateral foot pain.

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...

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...

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:16Bones of the Lower Limb: Femur and Patella
8.2K
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...

01:26Bone Markings
8.8K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:18Classification of Bones
14.3K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...
