Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Remodeling01:40

Bone Remodeling

41.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Bone Disorders01:29

Bone Disorders

8.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

17.7K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Compact Bone01:27

Compact Bone

23.2K
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...

Bone Cells and Tissue01:30

Bone Cells and Tissue

14.2K
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

Summary

This study details a rare case of pediatric osteoid osteoma recurring five times over 11 years, despite radiofrequency ablation. It explores potential causes for treatment failure in osteoid osteoma management.

Area of Science:

  • Orthopedics
  • Pediatric Oncology
  • Interventional Radiology

Background:

  • Osteoid osteoma is a common, benign bone tumor often associated with significant pain.
  • While typically self-limiting or treatable with single-session ablation, recurrence can occur.
  • Radiofrequency ablation (RF ablation) is a minimally invasive treatment option with high success rates.

Observation:

  • Presents an unusual case of pathologically confirmed pediatric osteoid osteoma with serial recurrences.
  • The patient underwent five separate RF ablation procedures over an 11-year period.
  • This case highlights the potential for persistent or recurrent osteoid osteoma in pediatric patients.

Findings:

  • Demonstrates that even with successful RF ablation, osteoid osteoma can recur multiple times.
  • Suggests that factors predisposing to incomplete treatment or recurrence warrant further investigation.
  • Highlights the challenges in managing complex or recurrent cases of osteoid osteoma.

Implications:

  • Challenges the notion of guaranteed spontaneous regression or single-treatment cure for all osteoid osteomas.
  • Underscores the need for vigilance and potentially tailored treatment strategies for recurrent pediatric osteoid osteoma.
  • May inform future research into the underlying mechanisms of osteoid osteoma recurrence and treatment resistance.
