Bone Disorders01:29

Bone Disorders

4.4K
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 Remodeling01:40

Bone Remodeling

38.9K
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.

Fractures: Bone Repair01:27

Fractures: Bone Repair

4.0K
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.4K
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

3.2K
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...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

4.9K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Summary

Patients treated with bisphosphonates had a higher incidence of complex and unstable hip fractures. This finding suggests a potential link between bisphosphonate use and fracture severity, impacting surgical treatment and recovery.

Area of Science:

  • Orthopedic Surgery
  • Geriatric Medicine
  • Pharmacology

Background:

  • Global increase in fragility hip fractures, impacting patient outcomes.
  • Fracture stability is crucial for treatment decisions and complication rates.
  • Unclear if metabolic therapies contribute to unstable fracture incidence.

Purpose of the Study:

  • To examine the association between bisphosphonate therapy and intertrochanteric hip fracture patterns.
  • Investigate if bisphosphonate use correlates with specific fracture classifications.

Main Methods:

  • Retrospective study of 370 fragility hip fracture patients (2013-2014).
  • Fractures classified as stable extracapsular, unstable extracapsular, or intracapsular.
  • Data collected on osteoporosis treatment, fracture type, prior fractures, and vitamin D levels.

Main Results:

  • 87 patients (23.5%) had prior bisphosphonate treatment.
  • Bisphosphonate users showed a higher rate of unstable fractures (56.3%) compared to non-users (27.9%).
  • Patients on bisphosphonates had a greater proportion of complex and unstable fractures.

Conclusions:

  • Bisphosphonate treatment is associated with a higher proportion of complex and unstable fragility hip fractures.
  • This association may influence surgical approach, complexity, and patient rehabilitation.
  • Further research is needed to understand the mechanism behind this observed link.
