L\u2019entorse de l\u2019articulation m\u00e9tacarpo-phalangienne du pouce est l\u2019une des blessures les plus fr\u00e9quentes sur les pentes de ski.<\/p>\n
Nombreux sont les skieurs qui ont d\u00e9j\u00e0 souffert d\u2019une entorse au pouce \u00e0 la suite d\u2019une mauvaise chute. La position \u00e9cart\u00e9e de la main, qui agrippe un b\u00e2ton ou tente d\u2019amortir un impact, entra\u00eene tr\u00e8s souvent un \u00e9tirement forc\u00e9 ou une d\u00e9chirure du ligament reliant les os \u00e0 la base du pouce. Les sympt\u00f4mes observ\u00e9s et les traitements recommand\u00e9s varient selon le degr\u00e9 de la l\u00e9sion.<\/p>\n
Signes et sympt\u00f4mes<\/h2>\n
La douleur est le premier signe indicateur de traumatisme. L\u2019apparition d\u2019enflure ou d\u2019h\u00e9matome, la sensibilit\u00e9 de la face int\u00e9rieure du pouce (c\u00f4t\u00e9 de l\u2019index) ainsi que la perte de force et de stabilit\u00e9 dans les mouvements de pr\u00e9hension (saisie d\u2019objets) sont d\u2019autres sympt\u00f4mes tr\u00e8s rapides. On recommande de consulter si la douleur et l\u2019enflure persistent apr\u00e8s 2 ou 3 jours ou si on remarque une g\u00eane durable ou amplifi\u00e9e au niveau du pouce.<\/p>\n
Diagnostic et traitement<\/h2>\n
Le m\u00e9decin devra d\u2019abord \u00e9valuer l\u2019\u00e9tendue de la l\u00e9sion avant de recommander un traitement. Des examens cliniques et radiographiques permettent de confirmer la gravit\u00e9 de l\u2019atteinte du ligament et de prescrire le type de prise en charge m\u00e9dicale appropri\u00e9.<\/p>\n
Les entorses b\u00e9nignes, caract\u00e9ris\u00e9es par un simple \u00e9tirement ou une d\u00e9chirure partielle, peuvent \u00eatre trait\u00e9es gr\u00e2ce au port d\u2019une orth\u00e8se d\u2019immobilisation ou d\u2019un pl\u00e2tre. Les entorses plus graves, lors desquelles des particules osseuses ont \u00e9t\u00e9 arrach\u00e9es ou le ligament a subi une rupture compl\u00e8te, n\u00e9cessitent une intervention chirurgicale. L\u2019op\u00e9ration, qui peut se faire sous anesth\u00e9sie locale \u00e0 l\u2019aide d\u2019une tr\u00e8s courte incision, consiste \u00e0 r\u00e9tablir la fonction de l\u2019articulation en utilisant un ancrage artificiel. La main doit g\u00e9n\u00e9ralement \u00eatre immobilis\u00e9e dans un pl\u00e2tre pendant quelques semaines suivant la chirurgie. Des traitements de r\u00e9\u00e9ducation peuvent aussi \u00eatre utiles.<\/p>\n
Pr\u00e9cautions<\/h2>\n
On recommande d\u2019op\u00e9rer dans les 10 jours qui suivent l\u2019accident afin de pr\u00e9venir les complications. Il est \u00e9galement important de savoir que les entorses graves non diagnostiqu\u00e9es et non trait\u00e9es peuvent laisser des s\u00e9quelles permanentes et \u00e9voluer vers une arthrose douloureuse.<\/p>\n
Il existe malheureusement peu de moyens de pr\u00e9venir ce type blessure. On sugg\u00e8re parfois aux skieurs d\u2019essayer de penser \u00e0 l\u00e2cher les dragonnes de leurs b\u00e2tons lors d\u2019une chute ou d\u2019une perte de contr\u00f4le. Comme pour bien des sports, avoir une attitude prudente et responsable peut \u00e9viter bien des d\u00e9sagr\u00e9ments. Bonne saison!<\/p>\n<\/span>\t\t\t\t\t<\/div><\/p>","protected":false},"excerpt":{"rendered":"Thumb metacarpophalangeal joint sprain is one of the most common injuries on the ski slopes.<\/p>\n
