Horses with sickle-hocks are at an increased risk of developing thoroughpin, curb and bog or bone spavins.
Very severe cases of sickle-hocks can result in permanent lameness and may require euthanization to prevent further pain.
However, many horses with sickle-hock are not affected to this degree, and may live a life with uneven wearing hooves.
Horses with sickle-hocks should be monitored closely for signs of lameness, and if possible a veterinarian should be consulted before extensive exercise.
Other animals who have this condition include, but are not limited to, cattle, sheep, and other types of livestock.
