Does the Craniolateral Approach Provide Better Exposure to the Radius than the Craniomedial Approach for Internal Fracture Fixation in Dogs?

Abstract

Objectives

To compare the exposure of the craniolateral approach (CLA) with craniomedial approach (CMA) of the radius in dogs. To make general observations of each approach that may affect the ease of fracture repair.

Study Design

Six canine cadavers were used in the study to compare the exposed surface area, length, and width of radius with CLA and CMA (n = 12).

Results

The CLA exposed a larger surface area of the radius compared with the CMA (p = 0.01). The CLA of the radius had greater proximal width compared with the CMA (p = 0.01). There was no significant difference in the length of exposed radii with either approach.

Conclusion

The CLA provided greater exposure for internal fixation of the radius in dogs.
