Tibial Plateau Leveling Osteotomy Plate with Offset

Abstract

The device is a tibial plateau leveling osteotomy (TPLO) plate is used to stabilize a stifle joint in an animal in veterinary surgery after a torn cranial cruciate ligament. The TPLO plate has a proximal portion and a distal portion, connected by an offset portion. The proximal portion and at least a portion of the distal portion are formed on two parallel planes.

AI Technical Summary

Benefits of technology

The present invention is a special plate used in animal surgery to treat a condition called tibial osteoatomy leveling plateau (TPLO). This plate has an offset part that connects the distal and proximal parts of the plate. The offset part can be at different angles, allowing the surgeon to choose the best position for the plate. The plate is designed to allow for the treatment of a specific condition and can be customized based on the patient's anatomy. The use of this plate helps improve the surgical procedure and makes it more effective in treating the condition.

Problems solved by technology

Current TPLO plates, when applied at an angle in a plane deviating from parallel to the long axis of the tibia, often result in abnormal angulation of the plate and screws, with the ensuing risk that a fixed angle screw could engage or enter structures such as joints, bones, or soft-tissue.

Where the tibial plateau is translated during TPLO and the plate becomes offset from the bone surface, there can be increased bending stress placed on the screws, leading to cyclical loading to failure at far fewer cycles.

Variations of anatomy, such as a mediolateral flared “trumpet-like” proximal tibia, can also lead to similar issues of plate offset from bone surface and angulation, even if the tibial plateau is rotated (leveled) without intentionally or unintentionally inducing translation in the mediolateral plane.
