Although mouse models are invaluable tools for bone tissue engineering, models of long bone defects are sparse. This need motivated development of the present protocol which uses a locking plate with four screws and a dedicated jig to perform and stabilize a reproducible, femoral, critical-size defect with low morbidity.

The evaluation of tissue development in the fracture callus during endochondral bone healing is essential to monitor the healing process. Here, we report the use of a magnetic resonance imaging (MRI)-compatible external fixator for the mouse femur to allow MRI scans during bone regeneration in mice.

Currently any kind of vascularized composite allotransplantation depends on long-term-immunosuppression, difficult to support for non-life-critical indications. We present a new porcine tibial VCA model that can be used to study bone VCA and demonstrate the use of surgical angiogenesis to maintain bone viability without the need of long-term immune-modulation.

Correct placement of the stethoscope on the chest corresponds to the sound of cardiac valves closing. The heart has two main sounds: S1 and S2. The first heart sound (S1) occurs as the mitral and tricuspid valves...
FAQs
Stabilization limits motion between the sternal segments while bone repair progresses. By reducing movement at the fracture or osteotomy site, fixation helps preserve alignment and supports restoration of chest-wall integrity. This mechanical support is important because persistent instability can interfere with healing and contribute to pain, poor union, or separation of the surgical wound.
Stainless-steel wires, plates, and screws serve as fixation materials that secure the aligned sternal halves. Although their specific configurations may differ, their shared purpose is to limit motion at the repair site during healing. Selecting a fixation approach therefore centers on maintaining stability of the sternum and supporting a reliable chest-wall closure.
Restricting movement helps maintain the position of the sternal halves and supports healing across the repaired site. Greater stability can also reduce sternal instability and associated pain, while helping prevent complications linked to poor union or wound separation. A secure sternum additionally helps protect the underlying thoracic structures during postoperative recovery.
The technique is most often used after median sternotomy or sternal fracture. Its clinical relevance spans cardiothoracic surgery, trauma care, and postoperative management, where the sternum must regain sufficient stability for recovery. These settings share a need to restore chest-wall integrity and limit problems associated with inadequate healing or unstable closure.
The central procedural sequence is to align the sternal halves and then secure them with an appropriate fixation material, such as stainless-steel wires, plates, or screws. This creates a stable closure while repair progresses. The intended result is restoration of chest-wall integrity rather than merely closing the incision over an unstable sternum.
Reliable fixation can support healing by maintaining sternal alignment and limiting motion at the repaired site. Clinically, this may reduce instability and pain while lowering complications associated with poor union or wound separation. In cardiothoracic and trauma settings, stable closure also contributes to postoperative recovery and protection of structures beneath the sternum.
