Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.3K
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 Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

9.7K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Bone Disorders

5.6K
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

11.4K
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 ...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

4.8K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Area of Science:

  • Orthopedic Oncology
  • Pediatric Pathology
  • Dermatopathology

Background:

  • Subungual osteochondromas are benign bone tumors occurring beneath or around the fingernail.
  • These tumors can lead to nail lifting, ulceration, and significant deformity.

Purpose of the Study:

  • To determine the incidence of subungual osteochondromas within a pediatric patient cohort.
  • To analyze the epidemiological characteristics of pediatric subungual osteochondromas.

Main Methods:

  • Retrospective, transversal, descriptive, and observational study design.
  • Review of histopathological records of osteochondromas diagnosed between 2001 and 2014.
  • Inclusion criteria focused on subungual presentation in pediatric patients.

Main Results:

  • Four cases of subungual osteochondromas were identified.
  • Equal gender distribution (1:1 ratio) with an average patient age of 9.5 years.
  • Predominance in the right hand (3:1 ratio) and most frequent occurrence in the 4th finger.

Conclusions:

  • Subungual osteochondromas constitute 8.5% of all osteochondromas.
  • Highlights the importance of considering subungual osteochondromas in pediatric differential diagnoses for nail deformities.
