LsTFLAiixiATiox OF BOXE.—In stud;s'ing inflammation of bone you should bear in mind that it is in the soft part^ (jf bone,—the periosteimi, the medullary membrane, and the delicate vascular connective tiss^ie which peiTades the Haversian canals and cancelli that the inflammation occurs, and that the pathological process, though some- what modified by the hard and resisting nature of the osseous framework, is essentially similar to that which occurs in the soft tissues. The same vascular and exuda- tive changes ensue, and are accomiianied by the like phenomena of redness, heat, pain and swelling. The in- flammation, moreover, may be of a simple and local, or of a diffuse and septic or infective character, and variously influenced by such constitTitional states as syjihilis, struma, gout, and rheumatism, or liy the presence of miliaiy tubercle. Further, it may terminate in resolution. or in sclerosis, caries, necrosis, or suppuration, condi- tions com])nrablc to fibroid thickening, ulceration, gangrcuo and sup]iuratiou of soft parts. On account of tlio intimate connection of the bone with tlie perio.t;t«'uni and medullary membrane inflanunation is seldom limited to any of these structures, and when one is affected the others generally soon become also involved.
