[Pancarpal arthrodesis using a "CastLess Plate" in dogs and cats]

Description of clinical experience with a new implant for dorsal plating in pancarpal arthrodesis. MATERIAL UND METHODS: Retrospective analysis (June 2008 - May 2009) of clinical records from a heterogenous group of dogs and cats which where treated by pancarpal arthrodesis using a PCA-plate ("CastLess-plate", Orthomed®, UK).

In 15 dogs and three cats, a total of 20 pancarpal arthrodesis (complete fusion of carpal joints) using a PCA-plate were performed. External coaptation by cast was not used in the postoperative period. In two out of 17 arthrodesis in 15 dogs serious postoperative complications (plate deformation, wound infection) occurred which required a revision surgery. Fistula formation (8-16 weeks post surgery) was seen in six arthrodesis. They all resolved after medical therapy. In cats, all three arthrodesis showed postoperative complications (bone resorption under the plate n=1, paw swelling n=2). Long-term evaluation by telephone interview with the owners (17 owners, 6-21 months after surgery, one case lost in follow-up) revealed good or very good results for 17 of 19 arthrodesis.

Pancarpal arthrodesis in dogs can be performed successfully using the "CastLess Plate" without additional external coaptation. Due to the size of the available implants complications have to be expected in cats.
