Boiterie chronique venant de l'epaule ...

Est-ce qu'elle avait déjà été ferrée?
Est-ce que la fourchette qui a tombé est sur la patte qu'elle boitte? (ps' je trouve ca vraiment vite une semaine pour que ca repousse).
Est-ce que vous l'avez essayé avant de l'acheter?
En longe elle semble stable?

Des pieds mal entretenus et des fourchettes de parti, ca prend beaucoup de temps avant que le cheval redevienne confortable (et ca prend plusieurs trimes avant q'avoir de bons pieds) Ca pourrait lui monter l'inconfort jusqu'à l'épaule.

Le fait que ca parte et revienne m'intrigue... peut-être que quelqu'un d'autre pourras t'en dire plus.

Il me semble que ce n'est pas la première fois que j'en entends parler... J'ai déjà entendu ça sur une Quarter Horse de lignée fondation. Me semble que sa fait partie des problèmes génétiques à tester chez les reproducteurs QH. Je cherche et te reviens avec ça.

PSSM (POLYSACCHARIDE STORAGE MYOPATHY) – Symptoms of this condition can include more than just muscle cramping. Some owners report poor performance, lack of energy, trembling after exercise, unwillingness of the horse to move forward, difficulty in backing up, stiff gait, difficulty in performing a balanced canter, unwillingness to lift the feet for hoof care, weakness of the hind limbs, gait abnormalities in the hind limbs due to sore muscles, loss of muscle (atrophy), tense and swollen muscles in the hindquarters, or sensitivity to pressure over certain muscles of the back and hindquarters.

HYPP affects muscle metabolism and affects the transport of sodium in and out of skeletal muscle cells. David McCarroll, DVM (Interstate Equine Services, Goldsby, OK) has dealt with many HYPP horses and he even treated Impressive, at Pilot Point, Texas, when he was in practice there. “I was called to treat him for colic in the late 1970s. In retrospect, he was having an HYPP attack, but we didn’t know it at the time. He was very, very weak, with his front legs and nose on the ground,” says McCarroll. The stallion had already had several colic surgeries during his lifetime, which may or may not have been necessary, since the pain from HYPP could easily be mistaken for colic.



“The primary problem in the muscle is in what’s called the sodium channel. The muscle is closer to being contracted than a normal muscle fiber,” explains McCarroll. “If it takes ‘x’ amount of influence to cause contraction of a muscle, a horse that has HYPP needs only about half the influence required, for that muscle to depolarize. It is thus more susceptible to contraction and will contract sooner, due to electrolyte abnormalities that occur at the cell membrane. The defective sodium channel does not open and close properly to allow the electrolytes inside and outside the cell to move in their normal manner, so the muscle contracts much more readily,” he says.



Signs of this muscle problem include muscle tremors and occasional prolapse of the third eyelid. “The classic early sign is muscle twitching and the skin seems to crawl; there are intermittent tremors, especially in the skin of the flank or muscles of the face. The horses also flare their nostrils,” says McCarroll. The horse sweats and has an elevated respiratory rate, often making a raspy sound as he inhales, because the muscles around the pharynx at the back of the throat collapse. Affected horses may drool because of the throat paralysis.



“As the condition progresses, the horse will collapse. No amount of prodding or encouragement will get him up; he is physically incapable of rising,” says McCarroll. The horse may lie there for an extended period of time without treatment, and get up after several hours, but treatment such as fluid therapy can shorten the recovery time. Some horses cannot be saved, however; they collapse and die. Heavy sedation—as when a horse is sedated for dental work or surgery—may bring on an episode, or may result in death of the horse.

Voici ceux que j'ai trouvé... Ça parle de l'arrière-main pour le PSSM, mais pas impossible par l'avant-main...

1% des boiterie vienne des épaules...sinon ca part des sabots en montant quand le forgeron a passé elle etait comment au ferrage quand il tappait les clous?
si la fourchette a poussé tres vite ca peut etre (et je suis pas vétérianire) un mécanise de defense de fourbure les talons et fourchette pousse bcp plus rapidement
faire venir un vet et faire prendre des radios
tout depandant ou vs lavez acheté demandé un historique sur elle
mais ce qui est sur c faut quel voit un vet!

Tu es sure qu'elle vient vraiment de l'épaule? Le syndrome naviculaire est souvent confondu avec une boiterie de l'épaule..

un cheval qui tombe sur le genoux, naviculaire est pas impossible (ma jument ca lui arrivait regulierement)

moi j irais probablement pour pousser les tests ce que miss_fey a posté aussi, le QH avec tous ce que j ai vu ces dernieres annees. Ca me fait un peu peur a cause de ca!

Souvent tu peux en voir beaucoup sur l etat du cheval sur a la facon dont il se tient au carré (si il ne tien pas son carré poses-toi des questions)

L autre truc louche: le merechal vous a rien dit? un bon marechal normallement a assez de connaissance pour voir ca en quelques minutes
