# Comparison of exposure of the feline radial diaphysis by the craniomedial and craniolateral surgical approaches for repair of antebrachial fractures

## TL;DR

This study compares two surgical approaches for accessing the feline radial diaphysis and finds they offer similar exposure for repairing antebrachial fractures.

## Contribution

The study provides a comparative analysis of two surgical approaches for feline radial diaphysis exposure, validating the craniolateral approach.

## Key findings

- The craniolateral approach provided a mean surface area of 4.13 cm² when including the supinator muscle.
- The craniomedial approach provided a mean surface area of 3.84 cm² when including the supinator muscle.
- The difference in exposure between the two approaches was not statistically significant.

## Abstract

To report and compare two surgical approaches to the feline radial diaphysis and outline optimal techniques to maximize surgical exposure.

Ex vivo experimental comparative study.

Left and right antebrachia of three feline cadavers.

Six feline antebrachia were collected from cadavers submitted for research purposes. Each limb was sequentially dissected for both craniomedial and craniolateral surgical approaches totalling 12 surgical approaches, or 24 when including and excluding the supinator muscle. Following each approach, photographs were taken and inserted into an image measuring software, to obtain the area of surgical exposure. The datum was then analyzed to ascertain which approach afforded the greatest exposure and whether the difference was statistically significant.

The mean surface area for the craniolateral approach, including and excluding the supinator muscle, was 4.13 cm2 and 2.63 cm2, respectively. The mean surface area for the craniomedial approach, including and excluding the supinator muscle was 3.84 cm2 and 2.45 cm2, respectively. The difference observed between the two approaches was not statistically significant (p > .05).

Surgical exposure achieved via the craniolateral and craniomedial approaches to the feline radial diaphysis is comparable.

This study validates the use of the craniolateral surgical approach to the feline radial diaphysis.
