Summary
Novel orthopedic fixation techniques enhance implant survival and performance. Innovations include mechanical interlocks, bio-adhesives, and tissue ingrowth, offering alternatives to traditional methods for joint disorders.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Biomedical Engineering
Background:
- Effective implant-to-tissue and tissue-to-tissue fixation is crucial for orthopedic procedures.
- Current fixation methods significantly impact orthopedic implant survival, performance, and integration.
- Traditional techniques may be superseded by advanced solutions for joint disorders.
Purpose of the Study:
- To review and overview novel fixation techniques for orthopedic joint implants.
- To identify alternatives and inspirations for future joint implantation procedures.
- To evaluate recent advancements beyond traditional fixation methods.
Main Methods:
- Literature search conducted using the Scopus search engine.
- Exclusion of traditional fixation keywords to identify innovative techniques.
- Inclusion of articles published between 2010 and 2020 for recent anchorage systems.
Main Results:
- Analysis of 57 studies revealed three primary fixation principles: mechanical interlocking, adhesives, and tissue-bonding.
- Mechanical fixations demonstrated the strongest anchorage.
- Adhesives and tissue ingrowth strategies showed promising, albeit preliminary, results.
Conclusions:
- Orthopedic fixation techniques are evolving towards application-specific designs.
- Bio-adhesives hold revolutionary potential but require further optimization.
- Tissue ingrowth approaches show promise for long-term fixation, necessitating further clinical validation.

3.9K
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...

01:03Structural Joints: Fibrous Joints
2.8K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

3.8K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
