Sprain Injury to a LIGAMENT from overstretching
Strain A pulled or torn MUSCLE
Synovitis Inflammation of the synovial membrane around a joint-swells from fluid accumulation
Tendinitis Inflammation of a tendon often from overuse
Windpuff Swelling of the pastern joint, a fluid filled distension of the joint bursa or capsule-usually only a blemish

White line disease white line becomes crumby and soft
Contracted Heels a condition where the horse’s heel is narrower than normal usually cases the horse to grow very upright heels

Laminitis inflammation of the laminae under the hoof wall
Navicular Disease inflammation of the bone which may affect the bone, bursa or tendon; afflicted horses will have heal pain and tend to point their toe at rest, usually occurs in the front feet only
Sidebone ossification of the lateral cartilage surrounding the pastern
Ringbone bony enlargement near coronet band that may involve pastern or coffin joint
Bowed tendon thickened enlargement of tendon/ligament that are in the cannon region formed by ruptured tendon tissue, most frequently superficial flexor tendon, deep digital flexor tendon, or suspensory ligament
Contracted tendons tendons are not able to stretch, in extreme cases horse will be up on tips of their hooves
