This protocol describes the tibial neuroma transposition model, which entails a lesion of the tibial nerve with subsequent transposition of the proximal nerve end toward a subcutaneous pretibial or lateral position. Behavioral testing of neuroma pain and plantar hyperalgesia is quantified using Von Frey monofilaments.

Surgical Angiogenesis in Porcine Tibial Allotransplantation: A New Large Animal Bone Vascularized Composite Allotransplantation Model

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.

(2023).This video demonstrates a procedure to generate a rat tibial neuroma transposition (TNT) model. After exposing the tibial nerve in the hind leg of an anesthetized rat, transect the nerve. Next, create a subcutaneous tunnel, thread the severed nerve through the tunnel, and suture it in place. In the absence of a target for reinnervation, disorganized axonal...

Creating Rigidly Stabilized Fractures for Assessing Intramembranous Ossification, Distraction Osteogenesis, or Healing of Critical Sized Defects

This article describes a method for stabilizing long bone fractures that is based on the application of modified Ilizarov external fixators 1-3. After application of the fixators and creation of the bone injury, healing can be assessed, distraction osteogenesis can be performed, or non-union or critical sized defect can be created and used to study therapeutic interventions.
FAQs
Plates and screws, intramedullary nails, and external fixation all maintain restored alignment, but they provide stabilization through different constructs. Internal devices maintain the fracture from within the limb, whereas external fixation supports the bone from outside and may be temporary or definitive. The surrounding soft tissues and severity of injury help determine which form of stabilization is appropriate.
Restoring alignment places the fractured bone in an appropriate position, while stabilization limits unwanted movement at the fracture site. Together, these principles create conditions for controlled healing and can support earlier rehabilitation when clinically appropriate. If alignment or stability remains inadequate, the limb may not recover normal structural support or function as effectively.
Soft-tissue conditions influence whether internal fixation is suitable or whether external fixation is needed, particularly when surrounding tissues are severely injured. Bone damage and blood supply also affect healing potential, while tissue injury can increase infection risk. These factors make the fracture environment as important as the broken bone itself when planning treatment and anticipating recovery.
External fixation may be selected when severe injury to the surrounding soft tissues makes immediate internal stabilization less suitable. It can serve as temporary support while tissue conditions are addressed or remain the definitive method of stabilization. Its role is therefore linked to the condition of the limb, not simply to the presence of a fracture.
The central operative sequence is to restore fracture alignment through reduction and then maintain that position with a fixation construct. Depending on the injury, surgeons may use plates and screws, an intramedullary nail, or external fixation. The selected approach must account for displacement, instability, soft-tissue injury, and the need for temporary or definitive support.
Operative treatment is particularly relevant for complex, displaced, open, or unstable tibial fractures. These injuries may not maintain suitable alignment or stability without surgical support, and open or severe injuries also raise concerns involving soft tissues and infection risk. Treatment aims to preserve limb structure while supporting healing and recovery of function.
Evaluation extends beyond whether the bone remains stabilized. Clinicians also consider fracture healing, maintenance of alignment, infection risk, blood supply, and recovery of limb function. Controlled healing may permit earlier rehabilitation when appropriate, but the eventual outcome depends on the original bone and soft-tissue damage as well as the stability achieved.
