Racing prognosis of horses following surgically repaired olecranon fractures. Olecranon fracture is a common orthopedic problem in juvenile horses. Prognosis for complete fracture healing when various methods of internal fixation are used is good; however, the impact of olecranon fracture stabilization on the likelihood that foals will start on a racecourse is unknown. Medical records of foals undergoing internal fixation for an olecranon fracture were reviewed. The dam's foaling records were obtained and lifetime racing records were then retrieved for both the affected foals and 1 of their siblings. Twenty-two of 24 repaired fractures healed completely, subsequently, 1...
Arthrodesis of the talocalcaneal joint for the treatment of two horses with talocalcaneal osteoarthritis. Two horses with lameness due to tolocalcaneal osteoarthritis that failed to respond to conservative management were treated by tolocalcaneal arthrodesis using cortex screws placed in lag fashion. The affected joint of one horse was arthrodesed by compressing and stabilizing the medial facet of the joint with three screws. In the second horse, the medial and lateral facets of the affected tolocalcaneal joint were each compressed and stabilized with two screws. The lameness of both horses improved markedly following surgery.

Tissue expansion. Tissue expansion in the upper extremity is a valuable technique with expanding indications and expected outcomes. The primary indications are coverage problems after trauma, but the technique is also applicable to defects caused by treatment of hemangioma, nevi, tattoos, or hypertrophic scars as well as correction of unstable tissue or as an alternative to free tissue transfer. The advantage of expansion-specifically, match in tissue texture and retention of sensibility-may be more important in the hand and upper extremity than in other areas. The inevitable capsule that forms around the expan...
Antimicrobial regional limb perfusion in horses. Regional limb perfusion involves administration of an antimicrobial solution into the vasculature of a selected portion of the limb that has been isolated from the systemic circulation by controlled application of a tourniquet.
