Greffé des deux mains, le petit Zion Harvey peut désormais écrire

L’enfant greffé des deux mains écrit

L'opération de Zion était une première mondiale.

Si le petit Zion est à présent capable de jouer au baseball, de s'habiller seul et d'écrire, l'enfant et sa famille sont tout de même passés par des épisodes douloureux. Zion avait subi une amputation des deux membres dans l'enfance, suite à une grave infection. Deux ans après, les progrès faits par Zion sont au-delà des espérances des médecins.

Le premier bilan de cette greffe, qui avait requis en juillet 2015 quarante médecins et une intervention de dix heures aux Etats-Unis, est publié mardi dans la revue médicale britannique The Lancet.

Mais rien n'a été simple pour le jeune Américain de 10 ans, qui a suivi des mois de thérapie et de soutien psychologique.

"Notre étude montre qu'une transplantation des mains est possible quand elle est soigneusement préparée et soutenue par une équipe de chirurgiens, de spécialistes des greffes, de thérapeutes professionnels, de psychologues et de travailleurs sociaux", a expliqué Sandra Amaral de l'hôpital pour enfants de Philadelphie (Etats-Unis) où l'opération a eu lieu.

"Elle ajoute: " Dix-huit mois après la greffe, l'enfant est plus indépendant et capable de conduire ses activités quotidiennes et continue à faire des progrès pour se servir de ses mains avec l'aide de thérapeutes et un soutien psychosocial", ajoute-t-elle".

Dans les jours ayant suivi la greffe des mains, il a pu bouger ses doigts. Il peut désormais écrire, s'habiller et manger seul. Six mois après, grâce à la repousse des nerfs, l'enfant a pu contracter les muscles des mains et sentir au toucher. Puis une batte de base-ball, un an après la greffe. De beaux progrès pour ce jeune garçon très courageux. Son corps a rejeté la greffe à plusieurs reprises, et les médecins ont été forcés de garder l'enfant à l'hôpital durant un long moment.

Pour son docteur, le but principal de sa greffe était qu'il " gagne de l'indépendance " en pouvant utiliser ses mains. Si au final la réussite de cette opération est encourageante pour la science, les chercheurs précisent qu'il faudrait davantage de données pour améliorer ce type de transplantations chez les enfants. La première greffe des mains et des avant-bras a eu lieu en janvier 2000 à Lyon, en France, sur un homme de 33 ans.
