Tibia Plateau Leveling Osteotomy: Saw and Jig

Fig 1: TPLO jig.

Fig 2: TPLO saw and jig.

The tibia plateau leveling osteotomy (TPLO) procedure dynamically eliminates cranial tibial subluxation associated with cranial cruciate ligament (CCL) disease in the dog, and thereby stabilizes the knee joint during locomotion. CCL rupture in the dog is similar to ACL injury in humans.

The standard saw and jig are designed specifically for use when performing tibial plateau leveling osteotomy to assist with location, guidance, initiation, and stabilization of the radial saw cut in medium and large breed dogs.

Disclaimer

The jig and saw guides can be used bilaterally (for right or left tibiae). Specially designed hinge and saw guide screws within the jig resist loosening under vibration. The hardened steel jig pin screws resist stripping. The saw guides can be positioned in multiple positions along the jig and the jig arm position can be adjusted to allow for optimal placement of the osteotomy. The saw guides are available in three radii of 24 mm, 27 mm, and 30 mm to match the saw blade size selected for an individual patient. The instruments can be easily disassembled for cleaning, and are made of medical grade stainless steel.

A smaller version of the jig and saw guides will be designed in the future for smaller breed dogs.

For description of the TPLO system please see TK News 1 | 08, page 37.
