Dr. Dao Van Giang, Deputy Head of the Department, said that the
thumb makes up 50% of the hand function, as one side of the pincer, and
missing the other side would make it hard for the patients to be able to
handle and work normally.
Patients with a thumb dislocation due to congenital
malformations or injuries from traffic accidents and daily activities should
undergo surgery to restore the thumb by replacing the damaged ones with toes.
At present, Viet Duc Hospital is applying the microsurgical
technique, in which moving the whole one-toed complex, including skin,
tendon, and toenails and then using neurosurgery to replace the damaged
thumb.
"Depending on the similarity of the thumb, we will take the
big toe or second toe to replace the thumb. Normally, doctors will take the
toe in the middle next to the great toe because of the similarity and
aesthetic aspect, while the function of the foot is not too affected much.
When moving the toe into the place of the thumb, we also combine surgeries to
reconnect the bone, tendon, blood vessels and nerves," Dr. Giang said.
A micro-surgery normally takes 6-8 hours. The new "thumb” after
restoration has the full function of folding, stretching and sensations.
