Review of Osteochondritis Dessicans in Horses

1 Introduction Developmental Orthopaedic Disease (DOD) of materialization, festering horses includes any racket in changing the cartilaginous harbinger of the skeleton to running(a) operating system (Anderson, 1996). One of the diseases included under this superior general precondition is Osteochondritis Dessicans (OCD) where a flap develops from the articular gristle payable to visitation of gristle to be properly converted into bone. It normally only affects young horses in any weight aim 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 may materialize in several different joints at the same time. 2 Development In young growing horses, squandered bones initially develop from gristle, showtime in the foetus and continuing after birth through to maturity. During development, two harvesting plates develop at each closing of the long b ones. The pineal gland faces the joint, and the metaphysis faces the shaft of the bone and together ar 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, terminal and calcification, vascular invasion, and finally, bone formation and remodelling (Briggs, 1997). As these steps occur, nutrients are provided by two sources, diff usion through the cartilage from the synovia! l fluid (fluid in the joint) and from the capillaries that are located in the alive 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 pineal body or the diaphysis. The thickening of the cartilage layer can take on some...
