Objective Description of surgical technique, complications and outcome of radius/ulna fractures in toy and miniature breed dogs treated with the paraosseous clamp-cerclage stabilisation (PCCS) method.
Study design Retrospective study.
Methods Clinical records of small breed dogs with fractures of the radius and ulna were reviewed between January 2011 and January 2016. Inclusion criteria were bodyweight of ≤3.5 kg, fracture of the radius and ulna of one or two limbs without previous repair attempts, available follow-up information, and the use of PCCS for repair of the fracture as the sole method of fixation.
Results Seventeen fractures in 17 dogs were included in the study. Radiographic union was documented in 13/17 cases. Median time to radiographic union was 13 weeks (range: 5–53 weeks). Major complications occurred in 24 per cent (4/17) due to implant failure, and for revision surgery the PCCS method was chosen in all four cases. Three of four revised fractures healed radiographically. One of the four dogs was lost for radiographic follow-up, but the owner could be contacted for a telephone questionnaire. Eleven of 17 dogs achieved an excellent return to function without any lameness during clinical examination, but 5/17 dogs showed an intermittent mild lameness despite full radiographic union. Routine implant removal was performed in 9/17 dogs. The owners of 15/17 dogs could be contacted for a telephone questionnaire for a long-term follow-up. No further complications were reported.
Conclusions PCCS is a feasible low-cost internal fixation technique for repairing radial and ulnar fractures in toy breed dogs. Further biomechanical and clinical studies are needed for better evaluation of the PCCS method.
