DSLD / ESPA (Degenerative Suspensory Ligament Desmitis)
Chronically progressive connective tissue disorder in which proteoglycans are pathologically deposited in tendons, ligaments and further tissues (hence also Equine Systemic Proteoglycan Accumulation, ESPA). Unlike a single tendon injury, DSLD is systemic and typically affects the suspensory ligament of several limbs. The disease occurs in familial clusters (among others Peruvian Paso), but the exact mode of inheritance is not conclusively clarified; DSLD is not curable.
Veterinary care required
This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.
Priority · vet & management
Diagnosis and follow-up (lameness examination, ultrasound) belong with the vet; in the foreground are adapted exercise/shoeing management and pain support. DSLD is not curable — complementary feeds cannot halt the degenerative process.
Possible causes
- · systemic proteoglycan accumulation in the connective tissue (tendons, ligaments, vessels, sclera)
- · familial clustering with a suspected but not conclusively clarified genetic component
- · breed disposition (among others Peruvian Paso, Arabian, Saddlebred, also Quarter Horse/Warmblood)
- · strain can worsen the course but is not the sole cause
Supportive compounds · supplementary feed, not medication
Prevention
Because of the familial clustering, information about affected lines and a careful breeding selection help to lower the risk in the offspring.
Equiterna's take
Equiterna classifies DSLD as a systemic, progressive connective tissue disorder — more than just one tendon: veterinary diagnostics and exercise management come first, without promises of cure through active substances.
