1.3 Locking System

Michael Kowaleski, Erik Asimus, Loic Déjardin, W Brian Saunders

The 1.3 Locking System is intended for the treatment of fracture and arthrodesis in canines and felines. This recently approved system, developed by our industrial partner DePuy Synthes in collaboration with the Small Animal Expert Group (SAEG) is a solution for fracture management in the smaller breed canine and feline population for which the 1.5 LCP System is too large.

The 1.3 Locking System consists of stainless steel 1.3 mm screws, locking plates, instruments, and an implant module set. The set contains an extensive range of implant options (Fig 1) to accommodate various fracture types and locations. The plates are low profile to minimize soft-tissue irritation (Fig 2). Stacked combi holes allow the use of a locking screw or a cortex screw in the same round conical plate hole (Fig 3) and the cut-to-length feature minimizes inventory. Screws are self-tapping and possess a self-retaining Star Drive recess which allows improved torque transmission and an increased resistance to stripping. The threaded head profile creates a fixed angle construct, and its low profile means that it sits flush with the surface of the plate.
