partial carpal arthrodesis plates

Where instability lies in the intercarpal or carpometacarpal joints and the radiocarpal joint is undamaged, partial carpal arthrodesis offers an outcome with a relatively normal range of movement. The problem is that the normal radiocarpal joint is capable of such a degree of extension that the distal radius tends to impinge on any implant placed onto the radial carpal bone. The image above shows a greyhound in full carpal extension illustrating the point very well. Vi's Partial Carpal Arthrodesis Plates have been engineered to have an extremely low profile. Additionally the proximal screw holes are very close to the proximal border of the plate thereby minimising the implant profile on the radial carpal bone. The proximal plate is precontoured for best possible fit and to allow best position and angles of screws. The largest plate accepts 2.7 and 3.5mm screws. Using 3.5 screws a smaller degree of screw angulation is possible. The medium plate takes 2.7, 2.4 and 2.0 screws. The smallest plate takes 1.5 and 2.0mm screws. Our TTO/ TWO plates have also been used successfully for partial carpal arthrodesis.
