Abstract

Objective:

To describe early clinical experience with a newly designed interlocking nail system (Targon® Vet) in diaphyseal fractures in cats and small dogs.

Study Design:

Retrospective case series.

Animals:

Client-owned cats (n=49) and dogs (n=8).

Methods:

Fifty-seven consecutive cases (49 cats, 8 dogs) with 60 long bone fractures were included in the study. Follow-up radiographs were scheduled at 4 and 8 weeks and again 6 months postoperatively. The end point for each case was determined radiographically by a healed fracture. Complications were defined as minor or major. Clinical outcome was subjectively assessed by a full orthopedic examination and follow-up radiographs. Descriptive data are reported.

Results:

Median age of cats was 18 months (range, 3–220 months) and of dogs was 28 months (range, 7–115 months). Median body weight was 3.7 kg (range, 1.67–8.41 kg) for cats and 8.15 kg (range, 2.68–13.6 kg) for dogs. Median radiographic follow-up was 16 weeks. All fractures with follow-up radiographs available (n=46) were healed with no infections reported. A total of 12 postoperative complications occurred: 3 minor (slippage of the locking screws) and 9 major (5 femoral—irritation of the sciatic nerve, stress protection, fracture because of a missed fissure, femoral neck fracture, intra-operative revision with a rod and plate; 4 tibial—3 with protrusion of the distal locking screw through the skin and 1 with in-growth of the intramedullary nail).

Conclusion:

Implantation of the Targon® Vet System was feasible in all cases. It provides an alternative system for diaphyseal fracture repair in cats and small dogs.
