Is it possible to reattach a severed limb?

Limb replantation is a complex microsurgical procedure that allows patients to have severed limbs reattached or “replanted” to their body. Most patients need limb replantation within hours of experiencing traumatic injuries. Depending on the type of injury you have, surgical specialists can replant some severed limbs.

Can limbs grow back?

Humans can do some regeneration — but most of it happens before we’re born. In humans, an embryo fewer than 8 weeks old can fully regenerate a lost limb — but after 9 weeks, scar tissue appears instead. Researchers are, of course, searching for ways to encourage more regeneration in humans.

Can a tongue be sewn back on?

Small injuries may often heal on their own. If the injury is long or deep, it may need stitches that dissolve over time. If a piece of your tongue was cut off or bitten off, it may have been reattached. Follow-up care is a key part of your treatment and safety.

While surgeons can sometimes reattach the yanked nerves to the spinal cord, this treatment is not as effective as physicians or patients would like. This is in part because nerves in the brain and spinal cord, unlike those in the rest of the body, fail to grow new nerve fibers.

Can dead nerves grow back?

When one of your nerves is cut or damaged, it will try to repair itself. The nerve fibres (axons) shrink back and ‘rest’ for about a month; then they begin to grow again. Axons will regenerate about 1mm per day. The extent to which your nerve will recover is variable, and it will always be incomplete.

Does exercise help nerve regeneration?

Treatment options typically focus on pain relief and treating the underlying cause. However, studies show that exercise can effectively preserve nerve function and promote nerve regeneration.

Can Vitamin b12 reverse nerve damage?

Supplementation for vitamin B12 deficiency should be provided parenterally since poor oral absorption is usually the cause of the disease. Supplementation with vitamin B12 typically halts progression of the disease, but does not reverse it since much of the disability is secondary to the spinal cord pathology.

Gabapentin remains among the most commonly used anticonvulsants for neuropathic pain. The established therapeutic dosing for gabapentin in neuropathic pain trials is 1800-3600 mg/day in 3 divided doses in patients with normal renal function. This means the minimum effective dose is 600 mg 3 times a day.

Study duration was typically four to 12 weeks.
