(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...

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.

FAQs
The transported cortical segment remains vascularized as it moves, while gradual mechanical distraction stimulates regenerate bone formation in the space created behind it. This links movement of existing tibial bone with production of new bone, allowing reconstruction to address a substantial defect rather than relying only on a separate graft to fill the missing segment.
Gradual distraction coordinates mechanical movement with the formation of regenerate bone. Moving the segment progressively allows new bone to develop behind it as transport continues, while the transported piece advances toward the opposite bone end. This controlled process can help restore continuity without sacrificing limb length, provided alignment is maintained during reconstruction.
An external fixation system provides the mechanical framework for controlling transport of the tibial cortical segment. It supports the gradual movement required for regenerate formation and helps maintain the intended limb alignment while the segment advances toward the docking site. Its role is therefore both mechanical and reconstructive, rather than simply immobilizing the limb.
The technique addresses bone loss by combining transport of a vascularized tibial segment with regenerate formation behind that segment. This differs from approaches centered on placing graft material into the defect. The distinction becomes especially relevant when segmental loss occurs alongside infection, impaired healing, or extensive tissue damage, circumstances that can complicate conventional grafting.
The reconstruction begins with a controlled corticotomy or osteotomy, followed by attachment of an external fixation system that enables gradual distraction. A vascularized cortical segment is then transported through the defect while regenerate bone forms behind it. The process continues until the segment reaches and docks with the opposing bone end, restoring continuity.
Clinicians may consider it for complex tibial nonunions or substantial segmental bone defects, particularly when infection, impaired healing, or extensive tissue damage complicates conventional reconstruction. Its value lies in addressing the missing bone while also offering a pathway to restore limb length and alignment, making it relevant to limb reconstruction in orthopedic trauma.
Successful reconstruction can restore continuity across a segmental tibial loss while preserving or restoring limb length and alignment. The method also creates new regenerate bone behind the transported segment and establishes a docking point with the opposing bone end. These combined outcomes make it a reconstruction strategy rather than a simple defect-filling procedure.
Tibial Cortex Transport illustrates how mechanical control and biological bone formation can work together in limb reconstruction. Instead of treating bone loss as an isolated gap, it addresses continuity, length, alignment, and healing conditions within one strategy. This is especially relevant in reconstructive medicine because complex trauma may combine structural loss with infection or compromised healing.
