Glossary

Caudolateral approach

The skin and subcutaneous tissues are incised beginning slightly proximal to the most proximal aspect of the olecranon (in the foal the apophysis of the olecranon) and extends distally between the muscle bellies of the ulnaris lateralis cranially and the superficial digital flexor caudally.
The exact length and position of the incision needs to be adjusted to the size of the horse and the location of the fracture.

Craniolateral approach to radius

An incision is made through the skin and subcutaneous tissues extending from the level of the elbow to the distal aspect of the radius located between the extensor carpal radialis and the common digital extensor muscles proximally and between the tendons distally over craniolateral and cranial aspect of the radius, respectively.

Medial approach to the radius

In cases, where a medial plate is required, an additional medial incision is required.
Because of the need to have a craniolateral exposure and a medial exposure it is indicated to have the horse placed in dorsal recumbency with the leg held in extension.

The medial incision is made straight over the medial aspect of the radius extending from the proximal to the distal physis. If there is a wound on the medial side the incision is curved to avoid touching the wound, if possible.

Stab incisions

The screws for the transphyseal bridge may be placed through stab incisions only.

If multiple wires are to be placed, a more substantial exposure may be required. The incision extends from the medial aspect of the distal radial epiphysis proximal to a level approximately 5 cm proximal to the distal radial physis.
