Bone Remodeling01:40

Bone Remodeling

34.4K
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 Disorders

8.0K
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.9K
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...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

3.5K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Transient Ischemic Attack l: Introduction

18
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Fractures: Bone Repair01:27

Fractures: Bone Repair

5.8K
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...

Summary
This summary is machine-generated.

Transient regional osteoporosis (TRO) affects weight-bearing joints in adults and pregnant women, causing pain and functional limitation. While often self-recovering, diagnosis can be challenging, especially during pregnancy.

Area of Science:

  • Orthopedics
  • Radiology
  • Rheumatology

Background:

  • Transient regional osteoporosis (TRO) is a condition causing fragility fractures in weight-bearing joints.
  • It affects mid-life adults and can occur during pregnancy, often at the hip.
  • Under-diagnosis may lead to an underestimation of TRO prevalence.

Purpose of the Study:

  • To summarize the key features, diagnostic challenges, and management of transient regional osteoporosis.
  • To highlight the differences between typical TRO and pregnancy-associated TRO.
  • To review current understanding and potential treatment approaches.

Main Methods:

  • Review of existing literature on transient regional osteoporosis.
  • Analysis of clinical presentation, diagnostic imaging (MRI), and outcomes.
  • Discussion of treatment strategies, including conservative and surgical options.

Main Results:

  • TRO presents with joint pain and functional limitation, often with spontaneous recovery.
  • Magnetic resonance imaging (MRI) is crucial for detecting bone marrow edema, even without densitometric osteoporosis.
  • Pregnancy-associated TRO poses diagnostic challenges due to patient age and overlapping symptoms.

Conclusions:

  • TRO requires careful diagnosis, particularly in pregnant women.
  • Antiresorptive therapy combined with symptomatic treatment shows promise.
  • Orthopedic interventions may be necessary for complications like fractures.
