Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.6K
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...

Compact Bone01:27

Compact Bone

18.2K
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...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

11.1K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Bone Disorders01:29

Bone Disorders

5.9K
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...

Spongy Bone01:09

Spongy Bone

9.3K
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...

Area of Science:

  • Orthopedics
  • Oncology
  • Radiology

Background:

  • Osteoid osteoma is a common benign primary bone tumor, representing 12% of benign and 2-3% of all bone tumors.
  • It frequently presents as localized bone pain, often exacerbated at night and relieved by NSAIDs.

Observation:

  • A 30-year-old patient presented with chronic ankle pain.
  • Radiographs revealed a heterogeneous lesion in the talar neck.
  • CT scan showed a nodular, hypodense lesion with minimal osteosclerosis.

Findings:

  • Histological confirmation of osteoid osteoma in the talar neck.
  • Imaging findings consistent with osteoid osteoma, including a nidus and surrounding reaction.
  • The lesion's location in the talus is a common site for osteoid osteomas.

Implications:

  • Accurate diagnosis of osteoid osteoma is crucial for appropriate management.
  • CT imaging is valuable for characterizing the lesion and guiding treatment.
  • Understanding the typical presentation aids in differentiating from other causes of ankle pain.
