Lameness

  • 1) level or intensity of work

  • 2) conformation and body condition - especially with structural defects

    • 1 - feet

    • 2 - joints

    • 3 - muscle

  • 3) most prone to lameness

    • too young

    • too old or worn out

    • pervious injury


Slide2 l.jpg

  • 4) training routines

    • inadequate warm-up and cool-down

    • 15-20 min of intensive work

    • rough up and down transitions

    • refusals, uncooperative

  • chronically uncomfortable horses

    • depression

    • appetite loss

    • changed resting habits

    • difficult in rising after rest


Slide4 l.jpg

  • routine check

    • soft swelling

    • thickening of tendons

      • strain

    • hard lumps on bones or joint edges

      • trama or calcification

    • elevated surface temperature/swelling

    • strong digital pulse on pastern

      • severe inflammation or infection in lower leg

    • upper muscle areas

      • limited freedom of movement


Slide5 l.jpg

  • hoof

    • check for heat - toe and heel

    • check back

    • press on the croup

      • 2/3 way from sacroiliac to tailhead

    • anything abnormal on one side and not the other

    • decreased performance sidedness

    • attitude

    • new pattern of movement

Treatment

  • rest

    • stop repeating painful activity

  • minimize destructive forces

  • avoid excessive painkillers
