Locking plates with combination holes have the disadvantage that the combination hole occupies a lot of space which results in hole spacing being too large. The consequence is that it may not be possible to place the desired number of screws in any bone fragment. At the 2009 BVOA scientific meeting there was a lengthy discussion regarding the value of incorporating Locking Screws into pancarpal constructs. Locking Screws add angular security which was generally regarded to be a good thing. The presence of compression holes was also considered to be desirable. Aaron Moles (Perth) considers that once the cartilage has been removed the carpus effectively becomes a comminuted fracture and questions whether placing a single screw in a small fragment (the radial carpal bone) is appropriate. All good fun! Veterinary Instrumentation has produced a small number of plates which offer a variety of combinations. Feedback from surgeons is appreciated. All radial carpal bone holes are round. In that situations which demand locking screws and plates rarely need DCP holes the VI locking plate offers only stacked holes which will take both locking and standard cortical screws but will not offer compression. The hole spacing is the same as that of a standard 2.7mm DCP. Plate profiles on page 362.

This Plate is as above but includes two DCP holes above and below the radial carpal bone hole. The above two plates have the same dimensions and hole spacing as 152907XL (see page 371.) VILock 3.5 Plates with Stacked Locking Holes Locking Plates with dual or combination holes are useful but typically the interval between holes is too large, limiting how many screws are possible in a fragment. The Stacked Locking Hole allows the use of both 3.5 Cortical Screws with limited angulation (7 degrees) and Standard Locking Screws having full angle security through the same round hole. While the mixing of locking and non locking screws in the same fragment is rarely indicated, it can be useful to place a screw outside the angular limitations of the locking hole. This Plate is effective ly a double hybrid in that it includes both locking and DCP holes of two different sizes. Proximal holes are 3.5, distal are 2.7 (2.7 or LS2724** series). LOCKING PANCARPAL ARTHRODESIS The cutaways underneath the plate are designed to offer low contact between plate and bone when using regular cortical screws. In addition they help create an even resistance to bending for easier contouring and reduced stress concentration at the screw holes.
