Dorsal recumbency

Dorsal recumbency

The horse is placed in dorsal recumbency with the leg extended.

Lateral recumbency

The horse is placed in lateral recumbency with the affected limb positioned uppermost.

Surgery in the standing horse


 

Preparation/Positioning

It is ideal to place the foal under general anesthesia to reduce and immobilize the limb. The metaphyseal spike may be medial or lateral. When the foal is placed under anesthesia in lateral recumbency for coaptation the spike is placed uppermost. This is because the periosteal attachments on the metaphyseal side tend to be more intact and gravity will help close the fracture.

Lateral recumbency

When the foal is placed under anesthesia in lateral recumbency the spike is placed uppermost. This is because the periosteal attachments on the metaphyseal side tend to be more intact and gravity will help close the fracture.

Preparation for ALD treatment

The animal is anesthetized and positioned in lateral recumbency on the surgery table with the surgical site up (in a varus deformity the affected limb is up, in a valgus deformity it is down).
If the deformity is bilateral, the animal is best positioned in dorsal recumbency on the surgery table, which allows performance of both surgical interventions without turning the patient over.
The affected region(s) is/are clipped and prepared for aseptic surgery. The entire animal is covered with a drape and a window is cut in the drape over the surgical site(s).

Preparation for osteotomies

The patient is positioned in lateral recumbency. Placement of the limb up or down is determined by the configuration of the osteotomy needed. This is determined from the preoperative planning.

Preparation for arthrodesis

The horse is placed in lateral recumbency with the effected limb up.
For the traumatic indications of a fetlock arthrodesis, a tourniquet should never be used because of the vascular damage caused.
