Def­i­ni­tion: in­flam­ma­tion of the lam­i­nae, the soft tis­sues that con­nect the cof­fin bone to the in­te­rior of the hoof cap­sule. In se­vere cases, the two struc­tures may sep­a­rate en­tirely, al­low­ing the cof­fin bone to ro­tate or sink down­ward, away from the hoof wall. The re­sult is the de­for­mity called founder.

Cau•e•: meta­bolic dis­or­ders, such as equine meta­bolic syn­drome and pi­tu­itary pars in­ter­me­dia dys­func­tion (PPID); sys­temic in­flam­ma­tory events, such as those caused by a grain over­load or an ill­ness such as Po­tomac horse fever; me­chan­i­cal stress or in­jury sign•: ex­treme pain in the af­fected feet, shift­ing weight from one fore­foot to the other, “sit­ting” back on the hindquar­ters to re­duce weight on the forefeet, strong dig­i­tal pulses, el­e­vated re­s­pi­ra­tory rate, slight fever and gen­er­ally un­com­fort­able look Treat­ment: Once signs of lamini­tis ap­pear, dam­age to the hoof is al­ready un­der­way. Re­search sug­gests that stand­ing a horse in ice wa­ter when the first signs ap­pear may help re­duce the sever- ity of an episode. A va­ri­ety of med­i­ca­tions can help re­duce pain and in­flam­ma­tion. Var­i­ous trim­ming and shoe­ing strate­gies may be used to help sup­port the hoof and limit or pre­vent ro­ta­tion of the cof­fin bone.

Progno•i•: Many horses can re­cover from a mild bout of lamini­tis, par­tic­u­larly if it did not progress to founder. When the cof­fin bone drops or ro­tates, how­ever, re­cov­ery may be long and un­cer­tain. Many horses are eu­tha­na­tized be­cause of the pain as­so­ci­ated with lamini­tis.
