OSTEOMYELITIS OF THE ENTIRE SHAFT OF THE HUMERUS—SEPARATION OF THE UPPER EPIPHYSIS—PRESENCE OF LARGE SEQUESTRA—SECONDARY INVOLVEMENT OF THE SOFT PARTS.

The holes bored by *.he pus through the walls of the bone arc repre-sented by the lighter circumscribed areas in the bone. The upper epiphysis has become separated from the diseased shaft andremains unaffected by the disease. The darker shadow of the soft parts shows their secondary PLATE XX. -6t- TUBERCULOSIS. Recognized on the radiogram by the paler hue of the boneshadow, the atrophy of bone, the epiphyseal prominence and, inthe later stages of the disease, bone destruction. Primary tubercular infection of the shaft of bones rarely oc-curs, except in the phalanges, metacarpal and metatarsal occurs most frequently in early life and is often associated withinvolvement of the joints. The tuberculous process causes a dis-appearance of the lime salts associated with a rarifying andformative process in the bone. This new tissue formation issimple granulation tissue. Whether in or near a joint, the dis-ease often simulates epiphyseal growth, which shows on the radio-graph as enlarged, pale and squared (Plate XXI), when com-pared with the normal side. As the process advances bone de-struction takes place, with sometimes the formation of sequestra(Plate XXII). The pus cavity may become circumscribed by aprocess of bone condensation (Plate XXIII), or may invade
