The OrthoPets carpus orthosis is commonly used for hyperextension injuries, instances of general palmigrade collapse or medial/lateral instabilities, as well as varus/valgus deformities.
Carpus mechanics depend on a 2-phase pressure curve. First, ground forces are transmitted to the carpus. Second, that force is absorbed by palmar fibrocartilage in the normal carpus. In the case of hyperextension, the palmar fibrocartilage cannot adequately resist the caudally-directed force and the joint collapses.
Mild to Moderate Hyperextension
In most cases of mild to moderate hyperextension, an articulating carpal orthosis without a paw segment will often provide the necessary stability without disturbing a dog’s proprioception.
The device allows for normal range of flexion movement, but when the joint returns to a neutral standing position, a motion limiter prevents the joint from breaking into hyperextension. Ground ground forces are transferred through the paw and into the mechanical hinge at the carpus. The articulating shell locks and the force is transmitted to the proximal antebrachium.
Severe or Multiplane Instability
In cases of bi- or triplanar instability, a non-articulating device with a paw segment is often appropriate.
A 3-point corrective system places counter forces at the antebrachium and paw which oppose corrective forces at the carpal joint to provide the necessary stability.
