Review of Osteochondritis Dessicans in Horses

1 Introduction Developmental Orthopaedic Disease (DOD) of materialization, growing horses includes any racket in changing the cartilaginous antecedent of the skeleton to running(a) rig out (Anderson, 1996). One of the diseases included under this popular precondition is Osteochondritis Dessicans (OCD) where a flap develops from the articular gristle imputable to visitation of gristle to be properly converted into bone. It normally only affects young horses in any weight front 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 analogous time. 2 Development In young growing horses, hard up bones initially develop from cartilage, showtime in the fetus and continuing after birth through to maturity. During development, two crop plates develop at each closing of the long bones. The pine al 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, expiry 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 capill aries that are located in the lively 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 render some...
