Review of Osteochondritis Dessicans in Horses

1 Introduction Developmental Orthopaedic Disease (DOD) of materialization, ontogeny horses includes any racket in changing the cartilaginous herald of the skeleton to running(a) prepargon (Anderson, 1996). One of the diseases included under this customary precondition is Osteochondritis Dessicans (OCD) where a flap develops from the articular gristle out-of-pocket to visitation of gristle to be properly converted into bone. It usually only affects young horses in any weight military strength fit of the body. OCD was first described in the horse in the femoropatellar enounce (stifle joint), which is one of the most common sites of the disease although it whitethorn materialize in several different joints at the alike time. 2 Development In young growing horses, purposeless bones initially develop from cartilage, showtime in the fetus and continuing after birth through to maturity. During development, two festering plates develop at each closing of the long bones. The pineal gland faces the joint, and the metaphysis faces the shaft of the bone and together are called the physis (Anderson, 1996). As the horse grows, there are several stages of familiar cartilage and bone formation. Normal endochondral ossification (the conversion of cartilage to bone near the joint) involves the following go: chondrocyte (cartilage cell) proliferation, maturation and growth, followed by chondrocyte degeneration, termination and calcification, vascular invasion, and finally, bone formation and remodelling (Briggs, 1997). As these steps occur, nutrients are provided by two sources, diffusion through the cartilage from the synovial fluid (fluid in the joint) and from the capillaries that are located in the actual bone (Anderson, 1996). In Osteochondrosis (a precursor to OCD), the cartilage is not replaced by bone in the normal manner. In affected areas, the cartilage might instead thicken and project into the bone of the epiphysis or the diaphysis. The thickening of the carti! lage layer can get some...
