Osteochondritis is a painful condition where the cartilage and bone in a joint is inflamed.^[1]

"Osteochondritis" often refers to osteochondritis dissecans (sometimes spelled dessecans, and abbreviated "OCD"). The term "dissecans" refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)". ^[2]

Another type of osteochondritis is Scheuermann's disease^[3], which affects the spine.

Inflammation

Acute

Plasma derived mediators	Bradykinin - complement (C3, C5a, MAC) - coagulation (Factor XII, Plasmin, Thrombin)

Cell derived mediators	preformed: Lysosome granules - vasoactive amines (Histamine, Serotonin) synthesized on demand: cytokines (IFN-γ, IL-8, TNF-α, IL-1) - eicosanoids (Leukotriene B4, Prostaglandins) - Nitric oxide - Kinins

Chronic

Macrophage - Epithelioid cell - Giant cell - Granuloma

Processes

Traditional: Rubor - Calor - Tumor - Dolor (pain) - Functio laesa
Modern: Acute-phase reaction/Fever - Vasodilation - Increased vascular permeability - Exudate - Leukocyte extravasation - Chemotaxis

Specific types
