By their experiments Gluck and Magnus prove that there is a return of activity after transplantation of muscle.

After excision of malignant tumors of muscles, Helferich of Munich, and Lange of New York, have filled the gap left by the excision of the muscle affected by the tumor with transplanted muscles from dogs.

Gluck has induced reproduction of lost tendons by grafting them with cat-gut, and according to Ashhurst, Peyrot has filled the gaps in retracted tendons by transplanting tendons, taken in one case from a dog, and in another from a cat.
Nerve-grafting, as a supplementary operation to neurectomy, has been practiced, and Gersung has transplanted the nerves of lower animals to the nerve stumps of man.
Bone-grafting is quite frequently practiced, portions from a recently amputated limb, or portions removed from living animals, or bone-chips, may be used.

Senn proposed decalcified bone-plates to be used to fill in the gaps.

Shifting of the bone has been done, e.g., by dividing a strip of the hard palate covered with its soft parts, parallel to the fissure in cleft palate, but leaving unsevered the bony attachments in front, and partially fracturing the pedicle, drawing the bony flaps together with sutures; or, when forming a new nose, by turning down with the skin and periosteum the outer table of the frontal bone, split off with a chisel, after cutting around the part to be removed.
Trueheart reports a case of partial excision of the clavicle, successfully followed by the grafting of periosteal and osseous material taken from a dog.
