Bone Remodeling

41.4K
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 Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

16.1K
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 Formation by Intramembranous Ossification

17.8K
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 ...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

11.1K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

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...

Summary
This summary is machine-generated.

Bone morphogenetic proteins (BMPs) show promise for enhancing bone healing in foot and ankle surgery, with limited studies indicating low complication rates. rhBMP-2 is the primary commercially available option, but its use is often off-label.

Area of Science:

  • Biochemistry
  • Orthopedic Surgery
  • Regenerative Medicine

Background:

  • Bone morphogenetic proteins (BMPs) are growth factors crucial for tissue development and maintenance.
  • Several BMPs possess osteogenic potential, acting through intricate regulatory pathways.
  • Currently, only recombinant human BMP-2 (rhBMP-2) and rhBMP-7 are clinically available, with rhBMP-2 being the predominant commercial form.

Purpose of the Study:

  • To review the existing literature on the use of BMPs in foot and ankle surgery.
  • To assess the efficacy and safety of BMPs as an adjunct to bone healing in this surgical context.

Main Methods:

  • Literature review of studies investigating BMP application in foot and ankle procedures.
  • Analysis of reported outcomes, including bone healing rates and complication profiles.

Main Results:

  • Limited studies suggest BMPs can yield promising results in foot and ankle surgery.
  • Reported complication rates associated with BMP use in these procedures are generally low.
  • BMPs serve as an adjunct to bone healing and do not replace the need for structural bone grafting.

Conclusions:

  • BMPs, particularly rhBMP-2, show potential as an adjuvant therapy for bone healing in foot and ankle surgery.
  • The use of rhBMP-2 outside of spinal fusions is considered off-label by the FDA and should be reserved for high-risk patients.
  • Further research is warranted to fully elucidate the role and optimal application of BMPs in foot and ankle reconstructions.
