Alocalised rarefaction of bone in the neighbourhood of a joint should arousesuspicion of the presence of pus, particularly when the bone round the rarefiedarea shows a tendency to condensation. The epiphysis may assume a worm-eaten appearance, which is distinctive of early caries ; later this maycompletely disappear. It is important also to be able to distinguish between tuberculous andnon-tuberculous disease of bone. In acute and subacute osteomyelitis.

Note the diiieicueebetween the two joints and relative shortening of neck on atiected side. affecting the neighbourhood of a joint, and particularly in the latter, thetendency is towards the formation of new bone, and the destructive processis not then so manifest. Irregular thickening of the periosteum with thedeposition of new bone favours a diagnosis of non-tubercular disease. Insome cases a degree of caries sicca preponderates in the process, and thenthere is not the same tendency to the formation of an abscess. The boneshows rarefaction for a considerable distance up the shaft. An accompanyingdegree of rarefaction of the bones entering into the joint results from therestriction of movement, and need not necessarily be taken as an indicationof the extent of the disease. Ankylosis of the joint may follow the healing 176 RADIOGRAPHY of the infl
