s other causes, such as fatigue,exposure to cold or wet, traumatism, syphilis, cancer, etc.,have been suggested. Some observers found spinal lesions intheir cases, others failed to find any, but arteriosclerosis of thevessels supplying the affected bones is found in almost everycase. Pathology.—The anatomical changes in Pagets diseaseconsist of waste of bone tissue in some places and hyperplasiain others. The Haversian canals in some localities are enlarged,in others, obliterated. There is no uniformity in location,degree or extent of these changes and all the bones may beaffected, but the most pronounced changes are found in thetibias and femurs. Owing to the softening of these bones andto the downward pressure of the body upon them, they becomecurved and the neck and shaft of the femur form a right angle.The marrow is very vascular and the periosteum is thickened. Symptoms.—The onset of the disease is insidious, oftenunnoticed until a change in the shape of the bone is observed.

Spondylitis Deformans. Irregular Contour. Backview.M. D., New York.) (Courtesy of S. Epstein, GOUT 351 In some cases there are vague pains and aches as in chronicrheumatism, occasionally there are paroxysmal sharp painsin the affected bones. Pain is sometimes present throughoutthe disease, in some cases aggravated upon walking, in somecases coming on in paroxysms, in other cases absent. Whenthe spinal column is pressed upon, as may occur in the deformitythat accompanies spinal osteitis deformans, or when a nerveis compressed the pain becomes increasingly severe. The mostimportant symptoms are thickening and malformation of thebones, the character and extent of deformity depending uponthe location of the affected bones and the amount of pressureto which they are subjected. For this reason the spine andlower extremities are most deformed, the increased curvatureof the spine producing a change in the shape of the thorax. The only disease which bears any marked resemblance toPagets diseas
