Summary
Objectives: To evaluate the use of Kirschner wires for treatment of fractures of the lateral
aspect of the humeral condyle in growing dogs.
Methods: Retrospective analysis of 35 elbow fractures (33 dogs) of the lateral aspect of the
humeral condyle treated by insertion of multiple transcondylar and one anti-rotational
Kirschner wires. Radiographic and clinical re-evaluations were carried out immediately
after surgery, at four weeks and, when required, at eight weeks postoperatively. Long-term
follow-up was planned after a minimum of six months. The relationship between different
implant configurations and clinical outcome was analysed statistically.
Results: Complete functional recovery was seen in 31 elbows (30 dogs), three elbows (2 dogs)
had reduction in the range of motion, and one elbow (1 dog) had persistent grade 1
lameness two months postoperatively. Major complications occurred in eight elbows
(8 dogs) and all were resolved by implant removal. Implant configuration did not affect
outcome. Long-term evaluation in 12 cases with a mean follow-up of four years showed
absence of lameness, normal function and no or mild radiographic evidence of osteoarthritis
in 11 cases.
Clinical significance: Fracture of the lateral aspect of the humeral condyle in growing dogs can be successfully
treated by multiple transcondylar convergent or parallel Kirschner wires, resulting
in adequate fracture healing.
