Summary
Trauma can rarely cause intramedullary fat globules in the bone marrow. These fat globules have a distinct appearance on both MRI and dual-energy CT scans.
Area of Science:
- Radiology
- Orthopedic Imaging
Background:
- Bone marrow imaging is crucial for diagnosing various orthopedic conditions.
- Traumatic injuries can lead to complex bone marrow changes.
Observation:
- Intramedullary fat globules are an uncommon finding following trauma.
- These globules present a unique imaging signature.
Findings:
- Magnetic Resonance Imaging (MRI) demonstrates characteristic signal intensities for these fat globules.
- Dual-energy Computed Tomography (DECT) provides specific material decomposition properties for fat identification.
Implications:
- Recognizing this pattern aids in accurate diagnosis of post-traumatic bone marrow changes.
- Distinguishing fat globules from other intramedullary pathologies is essential for appropriate patient management.

3.3K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

4.5K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

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...

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:18The Bone Matrix
3.2K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...
