Summary
Objective: To evaluate the effectiveness of circular external skeletal fixation (CESF) in treating
fractures of the distal radius and ulna in toy breed dogs, and to document the type
and frequency of complications associated with this technique.
Methods: The medical records of small breed dogs with fractures of the distal radius and ulna
admitted to the University of Turin and to the Clinica Ferretti between 2002 and 2009
were retrospectively reviewed. The criteria for inclusion of cases in the study were:
body weight of 5 kg or less, transverse or short oblique fracture of the distal third
of the radius and ulna, no previous repair attempts, and treatment with CESF as the
sole method of fixation.
Results: Twenty fractures in 16 dogs satisfied the criteria for inclusion into this study.
No signs of infection or failure of fixation were detected in any case. Mean frontal
plane alignment was 4.7° ± 2.7° and mean sagittal plane alignment was 12.7° ± 7.2°.
Postoperative complications occurred in one patient. All fractures achieved union.
Mean time until radiographic evidence of a bridging callus and subsequent implant
removal was 71 days (range: 30–120).
Conclusions: The results of this study support the use of CESF for treatment of fractures of the
distal radius and ulna in toy breed dogs as an alternative to other methods of fracture
fixation. However, this technique requires a series of follow-up examinations to evaluate
the stability of the apparatus, the soundness of the wires and to determine the appropriate
time for implant removal.
