Ankle Joint01:10

Ankle Joint

3.2K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.4K
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...

Bone Remodeling01:40

Bone Remodeling

40.7K
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

6.0K
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...

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Immunology

Background:

  • Aseptic loosening is the leading cause of revision for hip, knee, and ankle prostheses.
  • The complex and multifactorial mechanisms underlying aseptic loosening are not fully understood.
  • Periprosthetic osteolysis is a key factor contributing to aseptic loosening.

Purpose of the Study:

  • To explore the multifactorial nature of aseptic loosening in joint prostheses.
  • To identify key factors contributing to periprosthetic osteolysis.
  • To enhance understanding of implant failure mechanisms.

Main Methods:

  • Literature review of studies on implant loosening and osteolysis.
  • Analysis of factors including patient demographics, implant characteristics, and biological responses.
  • Synthesis of current knowledge on biomechanical and immunological aspects.

Main Results:

  • Aseptic loosening is a complex issue influenced by numerous factors.
  • Patient-related factors (age, weight, activity) play a significant role.
  • Implant-related factors (design, materials, fixation) and biological responses (immunology, biomechanics) are critical.

Conclusions:

  • A comprehensive understanding of all contributing factors is necessary to address aseptic loosening.
  • Further research into the interplay of these factors can guide the development of more durable prostheses.
  • Improving implant survival rates requires a multifactorial approach to treatment and prevention.
