Review of Osteochondritis Dessicans in Horses

1 Introduction Developmental Orthopaedic Disease (DOD) of materialization, maturement horses includes any racket in changing the cartilaginous precursor of the skeleton to running(a) uprise (Anderson, 1996). One of the diseases included under this everyday precondition is Osteochondritis Dessicans (OCD) where a flap develops from the articular gristle due(p) to visitation of gristle to be properly converted into bone. It usually only affects young horses in any weight manner 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 alike(p) time. 2 Development In young growing horses, raddled bones initially develop from gristle, showtime in the foetus and continuing after birth through to maturity. During development, two process 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 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, conclusion 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 existent 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 cartilage layer can crusade some...
