Pseudofracture, a reproducible murine model of sterile musculoskeletal trauma, allows for evaluation of late term post-traumatic immune responses. This article describes the procedural execution of the model step by step, including the potential for experimental model combinations to permit study of multiple trauma.

Acute brain trauma is a severe injury that has no adequate treatment to date. Multiphoton microscopy allows studying longitudinally the process of acute brain trauma development and probing therapeutical strategies in rodents. Two models of acute brain trauma studied with in vivo two-photon imaging of brain are demonstrated in this protocol.

We provide detailed methods for generating four types of tissues from human mesenchymal stem cells, which are used to recapitulate the cartilage, bone, fat pad, and synovium in the human knee joint. These four tissues are integrated into a customized bioreactor and connected through microfluidics, thus generating a knee joint-on-a-chip.

Structural Joints: Fibrous Joints
0 Views •
2025
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...
FAQs
The choice between controlled mechanical impact and joint-destabilizing procedures determines how injury is introduced and which biological changes can be examined. Impact models reproduce a force-related insult, whereas destabilization models reproduce loss of normal joint stability. Both can lead to cartilage disruption, inflammation, synovial responses, and changes in bone and ligament tissues, allowing comparisons of post-injury joint biology.
The initial injury can alter joint biology beyond the immediate tissue damage. Cartilage disruption may occur alongside inflammatory activity and synovial responses, while bone and ligament tissues also change. Tracking these connected responses over time helps researchers examine how trauma may progress toward post-traumatic disease rather than viewing damage as an isolated event.
The research question should guide both the injury approach and the tissues or responses selected for evaluation. A study focused on force-related damage may use controlled impact, while one examining instability may use a destabilizing procedure. This matching helps investigators interpret cartilage, inflammatory, synovial, bone, and ligament findings in the appropriate experimental context.
At a broad experimental level, researchers select either a controlled mechanical impact or a procedure that destabilizes the joint, then examine the resulting biological responses. The selected approach should reproduce the injury feature relevant to the study and support observation of tissue damage, repair, and later post-traumatic changes. Specific design choices therefore depend on the research objective.
Joint trauma models can provide platforms for evaluating imaging methods and biomarkers alongside changes in tissue biology. They can also be used to examine responses relevant to repair and to test rehabilitation strategies or potential therapies. Together, these outcomes help researchers characterize injury-related progression and assess whether an intervention changes the course of post-traumatic joint disease.
In medicine, these models support research into preventing osteoarthritis after musculoskeletal injury and improving treatment once trauma has occurred. By reproducing injury-related changes in cartilage, synovium, bone, and ligaments, they give investigators a way to study post-traumatic disease mechanisms and evaluate rehabilitation strategies, imaging approaches, biomarkers, and potential therapies within an experimental setting.
