Management Plan: Based on our diagnosis of a complete transverse displaced articular fracture of the olecranon, we recommend treatment with a dynamic narrow compression plate. With this method we will contour fit a compression plate to the caudal side of the olecranon and use a combination of lag and cortical screws to fasten the plate in place. Repositioning of the fractured olecranon prior to fixation will be critical to ensure that a normal articular surface is re-established on the anterior olecranon. Because the foal is less than 6 months old, we need to ensure that no screws are placed into the proximal radius. One long lag screw will be placed on the proximal tip of the olecranon, positioned so that it passes through the olecranon fracture at a 90-degree angle. The lag screw will bridge the olecranon fracture and fasten it firmly to the proximal ulna. An appropriate sized lag screw will be selected so that the threads are only present in the proximal ulna distal to the olecranon fracture. Six additional cortical screws will be placed to secure the compression plate against the caudal olecranon. Cortical screws will be placed at 90-degree angles to the compression plate, with three screws being placed proximal to the fracture and three screws distal to the fracture. The three distal screws will be selected at an appropriate length to ensure that they do not penetrate the radius. Appropriate length cortical screws for fixation of the proximal portion of the compression plate will also be selected to ensure that penetration of the elbow joint does not occur. Postoperative treatment will include bandaging of the entire forelimb, in the area of the fracture and distal to it, to minimize edema and prevent contamination of the surgical site. Our patient will be put on perioperative antibiotics (a combination of Ceftiofur, K-penicillin and Metronidazole) to prevent osteomyelitis and sepsis. We will instruct the owner to confine the foal to a stall for six to eight weeks. We will also forewarn the owner that the foal may show marked improvement immediately postoperative but the six to eight week period of rest is mandatory to promote adequate healing. Since the three distal cortical screws will not penetrate the radius, removal of the compression plate will only be completed if complications result such as rejection of the compression plate. The prognosis for our patient is good if the therapy described above is applied and adequate alignment of the fractured olecranon is established prior to fixation. According to Pasquini there is a 76% chance that the foal will return to normal function after surgery. However since this fracture involves the elbow joint and has the potential to cause degenerative joint changes our prognosis may not be as good as the 76% chance described above. Nevertheless we feel that it is highly likely our patient will return to normal function postoperatively and we consider the risk of degenerative joint disease to be minimal.
