Arthroscopic injection of corticosteroids into the fibrous tissue of subchondral cystic lesions of the medial femoral condyle in horses: A retrospective study of 52 cases (2001-2006) Reasons for performing study: There are no published results of subchondral cystic lesions (SCLs) in the medial femoral condyle (MFC) treated with arthroscopic injection of corticosteroids into the lining of the cyst. Objectives: 1) To determine the success rate for treatment of SCLs in the MFC with arthroscopic injection of the fibrous tissue of the cyst with corticosteroids.

Objective—To determine outcome of Standardbred racehorses with moderate to severe midbody suspensory ligament desmitis (MSD) treated by means of ultrasound-guided intralesional injection of a single dose of platelet-rich plasma (PRP) followed by a program of gradually increased exercise.

Design—Nonrandomized clinical trial.

Animals—9 Standardbred racehorses.

Objective—To determine whether clinically effective concentrations of methylprednisolone or triamcinolone can be achieved in the navicular bursa after injection of methylprednisolone acetate (MPA) or triamcinolone acetonide (TA) into the distal interphalangeal joint (DIPJ) and whether clinically effective concentrations of these drugs can be achieved in the DIPJ after injecting the navicular bursa with the same doses of MPA or TA. Animals—32 healthy horses.

Sacroiliac lesions are commonly suspected in sport- and racehorses. Injection of the sacroiliac (SI) area can be performed for diagnostic purposes and/or for treatment of SI pain. Because of the deep location of the SI joint, blind injections may be unsafe. The purpose of this paper is to present how to perform ultrasonographic guided injection of the SI area using cranial and caudal approaches. With this technique drugs can be injected close to the SI joint and technical errors (needle implantation in the sciatic nerve, injection in the vertebral canal or in the rectum) can be avoided.
