I found these online somewhere, so I take absolutely no credit for these!

What is a Bone Spavin?
Bone Spavin is arthritis in the small bones of the hock, caused by too much stress or concussion. If the calcium deposits cause the bones to fuse together, the horse may recover completely; if not, he may be permanently lame. Appears as a hard swelling low on the inner hock.
What is a Bucked Shin?
Bucked Shins are an inflammation of the bone covering the front of the cannon bone, usually in the front legs. The shin becomes very hot and sore, and the horse is lame. It is usually seen in young horses worked too hard. The lameness subsides with rest and treatment.
What is Carpitis?
Carpitis is an inflammation of the knee, caused by stress or trauma. Often seen in racehorses or horses with calf knees, The knee becomes hot, tender, and swollen, and the horse may move his leg in a sideways arc. The lameness may subside with rest and treatment, or require surgery.
What is Sidebone?
Sidebone is the collateral cartilages of the coffin bone, which form the bulbs of the heel, gradually calcify and turn to bone. This usually is not considered an unsoundness unless the side-bones become very large or get broken, causing lameness. Most common in horses with straight pasterns.
What is Curb?
Curb is a sprain of the plantar ligament running down the back of the hock, caused by an extra strain on the hock and usually resulting in lameness. Seen as thickening at the back of the lower hock; may be visible as a blemish after the ligament has healed.
What is High Ringbone?
High Ringbone is basically arthritis (calcification and inflammation) in-between the two pastern bones, caused by stress and concussion. Eventually the bones may fuse and the horse will be sound, but high ringbone has the danger of developing into low ringbone, which is more serious.
What is Low Ringbone?
Low Ringbone is basically arthritis (calcification and inflammation) in-between the end of the pastern bone and the coffin bone, where is cannot be seen without x-rays. This is the most serious type of ringbone, caused by stress and concussion, and the horse may become permanently lame.
