Method and apparatus for correction of defects in an equine leg

Method and apparatus are disclosed for treatment of various defects in an an animal's leg, particularly the leg of an equine. The apparatus includes a brace attached to the animal's leg at three points. Two pivotal connectors are arranged to be adjacent the knee and ankle joints of a horse's leg, and the spacing between opposed connectors is adequate to accommodate any expected varus or valgus deviation. A pad is provided for engaging a deviated joint and pulling it against a side of the brace to correct the deviation. In accordance with the method of the invention, deviation is corrected by applying the brace to the leg and pulling the deviated joint into its correct position by application of a force with the pad. The pivotal connectors include stop elements to limit the extent of angular motion. A method for treatment of contracture is disclosed whereby a brace is applied to the contracted leg, and the leg is extended in successive steps and prevented from returning to the contracted position by application of the stops. The brace may be applied to either the foreleg or the rear leg of an animal by a simple modification. |

DETAILED DESCRIPTION In accordance with the invention, method and apparatus are provided for correction of various defects in an animal's leg.
In the preferred embodiment, the apparatus comprises three separate sections of relatively figid braces with adjacent sections being connected by pivotal elements.
The pivotal elements are spaced such that one may be placed approximately adjacent the knee joint of a foal while the second is placed approximately adjacent the ankle joint of the foal.
A hoof-engaging element is pivotally attached to the lower end of the lower set of braces, a first attachment band is located between the pivotal elements and a second attachment band is located above the upper pivotal element.
The pivotal elements are arranged to provide movement of the three brace sections in a common plane or parallel planes so that the device, in essence, establishes a reference direction for movement of the parts of the leg.
The spacing between opposed pivotal elements is large enough to accommodate any expected varus or valgus deviation so that the apparatus may be attached to a deformed leg.
In the method of the invention, a pad is used to pull a deviated joint against one of the side braces to urge that joint into proper alignment.
By this technique, deviations in both the ankle and knee joints are simultaneously corrected.
When applied to a rear leg, misalignment of the tarsal is easily corrected.
Because the apparatus provides pivotal connections, the foal is allowed to walk about, does not view the apparatus as a foreign object, and does not injure itself trying to get away from the apparatus.
Use of the apparatus also relieves pressure on a crushed or deformed knee by properly aligning the weight-bearing carpals.
A similar result occurs in the sesamoid bones of the ankle.
The apparatus is also useful for treatment of contractures because the preferred pivotal elements include limiting stops for controlling the angular motions of the brace.
A contracture is a deformity where an animal is born with a leg which cannot be extended due to shortened muscles, ligaments, or other dysfunction
