TUBERCULOSIS OF THE LOWER END OF THE FEMUR—SECONDARY 1 THE KNEE JOINT. The lower end of the femur is enlarged and its lighter shadow indicatesbone rarefaction. The epiphyseal line is Inst. The epiphyses of both the fcnuir and the tibia arc pale, enlarged andsquared. New formation granulation is present between the patella and the femur,between the femur and tibia, and in the peri-articular PLATE XXI. — 70 — PLATE XXII. TUBERCULOSIS OF THE BONES OF THE WRIST—PRESENCE OF SEQUESTRA. Tubercular involvement o{ the lower end of the radius, with destructionof its articular surface, and loss of bone substance on the outer surfaceof the bone. Extensive involvement and destruction of the carpal bones. The trapezium is the only one of these that can be distinctly made out. The whole wrist presents the appearance of one mass of tuberculargranulation tissue, with irregular darker areas of bone necrosis. On the ulna side the secondary involvement of the soft parts and thepresence of pus are well marked.
