Smarty – a seven year old bay Hanoverian mare
Smarty was examined as an outpatient on the 24th July 2013 for medication of both sacroiliac joints following examination of the horse at home. Smarty had previously had arthroscopic surgery on both hind fetlock joints for OCD lesions and had made good progress after that surgery. In the bone scan which led up to the initial diagnosis of OCD, uptake in both sacroiliac joints had been noted. When examined at home recently Smarty was sound at the trot but showed marked dynamic abnormalities at the canter which showed her to be struggling at the canter with little hindlimb impulsion and being very heavy on the forehand. Using the results from the previous bone scan, it was felt that the sacroiliac joints were likely the most plausible explanation for the dynamic signs. Both left and right sacroiliac joints were medicated on the 24th July under sedation with 160 mg of DepoMedrone in total and Smarty was discharged back to her owner that day. If the clinical signs do not respond to treatment then the diagnosis can be reviewed.

Fast Back 2013 – a bay Thoroughbred filly
The above filly was admitted to the Valley Equine Hospital on 5th June 2013 for placement of stainless steel wires to treat a parrot mouth conformation. Following identification of a heart murmur prior to a scheduled anaesthetic the foal was examined by Mark Patterson who diagnosed functional flow murmurs which would not be of any detriment to the foal. In light of this the foal was re-admitted and anaesthetised on the 6th June for surgery. In this foal the severity of the over bite meant that a bite plate also needed to be fashioned which was completed with a small piece of aluminium which was secured on to the maxillary incisors and the wires with Imprint granules. The filly's overbite was 2.5 cm. Surgery entailed placing 18 gauge stainless steel wires via incisions through the cheek and holes drilled between the cheek teeth to show the growth of the maxilla. The skin incisions through the cheek were left to heal by secondary intention. The foal was discharged on June 7th with a course of oral antibiotics and anti-inflammatories. Each day the wires should be examined to ensure they are intact. Any food which has become trapped in the wires should be removed daily. The length of time before failure of the wires is completely variable, but ultimately the wires will loosen or break and require changing. Correction from the wires is on the order of half a centimetre per month and a significant improvement in the oral conformation is anticipated.
