Evaluation of joint stabilization for treatment of shearing injuries of the tarsus in 20 dogs

Medical records of 20 dogs with 23 shearing injuries of the tarsus leading to joint instability were reviewed. A transarticular external skeletal fixation device or prosthetic ligament was used to stabilize the joints. The most common complications were fixator failure and implant infection. The median times for wound healing and maximal joint function were 10 and 12 weeks, respectively. Clinical outcome was excellent in 22%, good in 56%, and poor in 22%, Comparison of the two stabilization methods showed no statistically significant differences in healing time, time to regain function, or clinical outcome.
