Traumatic injury to the spinal cord disrupts communication with the brain. To restore lost connectivity we utilize a peripheral nerve graft to provide a substratum for regenerating fibers in combination with neurotrophic factors and matrix-modulating enzymes to remove inhibitory molecules to promote long distance growth.

Source: Svientek, S. R., et al. Fabrication of the Composite Regenerative Peripheral Nerve Interface (C-RPNI) in the Adult Rat. J. Vis. Exp. (2020).This video demonstrates the surgical construction of a composite regenerative peripheral nerve interface (C-RPNI) in a rat model of peripheral nerve injury. The procedure involves attaching a transected peroneal nerve to a muscle graft and overlaying it with a dermal skin graft to promote nerve regeneration. Over time, motor and sensory neurons...

Source: Zimmermann, S., et.al. Stromal Vascular Fraction-enriched Fat Grafting for the Treatment of Symptomatic End-neuromata. J. Vis. Exp. (2017)This video demonstrates the surgical procedure for neurolysis and stromal vascular fraction (SVF)-enriched fat grafting in the management of symptomatic neuroma. Neurolysis removes adhesion tissue to restore nerve gliding, while SVF-enriched fat grafting is applied around the nerve to create a protective barrier, support nerve healing, and enhance...

We describe protocols for our mouse graft arteriosclerois (GA) models which involve interposition of a mouse vessel segment into a recipient of the same inbred strain. By backcrossing additional genetic changes into the vessel donor, the model can assess the effect of specific genes on GA.

The purpose of the study is to illustrate the technical procedure of stromal vascular fraction (SVF)-enriched fat grafting as a novel treatment of symptomatic end-neuromata. This technique provides advantages of both the mechanical barrier and the biological action at the cellular level by the processed and concentrated SVF.
FAQs
Axons from healthy facial nerve fibers grow through the implanted graft toward the paralyzed side. As these fibers regenerate, they create a pathway for electrical signals generated by the functioning side to reach facial muscles or a transferred muscle. This regrowth is what allows the reconstructed side to respond to voluntary facial movement.
The healthy side provides active facial nerve fibers capable of producing movement-related electrical signals. Connecting the graft to these branches gives the paralyzed side access to the patient’s existing facial motor activity rather than relying on inactive nerves. This arrangement supports movement linked to actions such as voluntary smiling and can improve facial symmetry.
The recipient end of the graft may be attached directly to facial muscles or to a free muscle transfer. Both options provide tissue that can receive regenerated nerve signals and produce movement. The overview identifies these as alternative targets, allowing reconstruction to be adapted to the available facial muscle or transferred muscle tissue.
The procedure involves identifying healthy facial nerve branches, harvesting a nerve graft, routing it beneath the skin across the face, and connecting its ends to the functioning nerve fibers and the selected recipient muscle tissue. The microsurgical connections establish the intended pathway, after which axons regenerate through the graft toward the affected side.
A nerve graft is often obtained from the leg because it can serve as a bridge between facial structures on opposite sides. Surgeons route this graft beneath the facial skin and connect its ends microsurgically. Its role is to provide a physical pathway through which axons can regenerate toward the affected facial muscles or transferred muscle.
This technique is used for patients with long-standing facial paralysis when reconstruction aims to restore movement on the affected side. By linking that side to functioning facial nerve fibers, treatment can support voluntary smiling and improve facial symmetry. These functional changes may also contribute to psychosocial recovery by improving facial expression.
