Tibial Plateau Leveling Osteotomy Plate with Offset

a technology of osteotomy plate and plateau, which is applied in the field of tibial plateau leveling osteotomy plate, can solve the problems of cyclical loading to failure at far fewer cycles, abnormal angulation of the plate and screws, and fixed angle screw could engage or enter structures such as joints, bones, soft tissues, etc., and achieve the effect of facilitating the placement of tplo plates

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.

Embodiment Construction

[0014]The present disclosure relates to a tibial plateau leveling osteotomy (TPLO) plate with offset for a tibial plateau leveling osteotomy. The offset allows for translation of the osteotomized segment medially or laterally for alignment of the tibia, patella and quadriceps. This plate can be used for an apparatus in veterinary surgery for orthopedic surgical translation of an osteotomized segment in canines, felines, and other quadruped animal species, both domestic and exotic. The plate can be used to repair a torn cranial cruciate ligament while concurrently repairing a chronic pre-existing patella luxation.

[0015]The TPLO plate with offset allows translation of a proximal tibial segment while maintaining plate alignment parallel to a tibial long axis and screw alignment parallel a joint surface to minimize the risk of unacceptable screw impingement. The TPLO with offset minimizes plate-to-bone distance to minimize a risk of screw failure, and allows a surgeon to adapt to abnorm...

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.
