Abstract

The aim of this study was to describe the clinical use of a titanium locking plate and screws as an adjunct for the surgical treatment of an open, transverse, mid-body patellar fracture. A 2-year-old crossbreed dog was diagnosed with an open, transverse, mid-body patellar fracture. Initial fracture reduction and compression were achieved with two parallel Kirschner wires and a figure of eight tension band wire. This was followed by a titanium locking plate and screws placed on the cranial aspect of the patella. A transarticular circular external skeletal fixator was used as an additional augmentation for 5 weeks. Wire failure was noted in the transarticular circular external skeletal fixator at 10 days postoperation, necessitating wire replacement. Complete return to previous activity level and progressive radiographic osseous union were observed 8 weeks after surgery. Breakage of the Kirschner wires at the proximal pole of the patella was noted 3 years after surgery and explantation of all implants was performed. Recheck evaluation at 8 months after explantation confirmed full return to athletic function. This case report described the clinical use of a locking plate and screws as an adjunct for transverse patellar fracture repair and its long-term functional outcome.
