General surgical pathology and therapeutics, in fifty lectures : a textbook for students and physicians. mation of bone was strong enough to carry the body; sub-sequently, under chloroform, the knee was straightened, and perfectrecovery resulted. I saw a perfectly similar case affecting the lowerend of the humerus. In both cases, as is usual in necrosis near thejoints, the joint had suffered severely, and became quite stiff. Still,even without early detachment of the sequestrum from softening- ofthe epiphyseal cartilages, undercircumstances which we do not accu-rately know, the formation of bone may be very feeble, so that, afterthe detachment, the new bone is not firm at some point, but is quiteflexible, whereby we have a pseudarthrosis of the new bone; I haveseen two cases of this kind: one of these I cured completely by occa-sionally driving- ivory plugs into the weak part of the newly-formedbone, thus constantly stimulating the bone to new production; theobject was attained in the course of eight months, and the patient,then twelve years old, now walks like a healthy person. Fig. small diagram of partial necrosis of a hollow bone. 456 CHRONIC INFLAMMATION OF THE PERIOSTEUM, BONE, ETC. Partial necrosis of the diaphysis is more frequent than the abovecomplete necrosis; this may either atfect the entire thickness, or onlyhalf the circumference, according to the extent of the osteomyelitis andperiostitis. You may readily apply what has been said to these par-tial necroses. Here is an example: suppose a periostitis of part ofthe diaphysis of one femur and subsequent necrosis ; the circumstancesmay assume the following shape (see Figs. 86 and 87): a, seques-trum ; b 5, its borders; c c, the pus-cavity; d, the perforation out-ward ; e e, the thickened ossifying wall of the pus-cavity. A few months later (Fig. 88); a, detached sequestrum, which is to Fig. 87.
