[Revascularization of the forelimb in dogs].

Revascularization of the forearm was performed on six mature dogs of a different race. Arteria mediana was cut 2 cm above the fork of the arteria radialis and later sutured with a nonresorptive monofilament thread/Ethilonr/7-0 and 8-0 in diameter. The same process was repeated on the cefalica vein.

[Degenerative arthritis of the knee joint after allotransplantation of the joint surface without immunosuppression].

Degenerative arthritis of the knee joint after resurfacing of the knee with fresh osteochondral allograft occurs frequently and was noticed a long time ago. The main causes can be: incongruity of the joint, when the allograft slips so that its surface is out of normal line, inadequate internal fixation different methods of cartilage preservation which are lethal to cartilage, broken grafts as well as immunological reaction to the graft. The experiment was conducted on 5 dogs, i.

[Incorporation of nonvascularized auto- and allotransplanted bone into the site of bone defects].

It is generally accepted viewpoint that free bone grafts do not survive transplantation, that the incorporation of the autograft is faster and safer than the one of the allograft, and that the immunological processes disturb the process of revascularisation and reossification of the graft, although they stimulate the process of absorbtion. The process of graft incorporation into the host's bone was followed up in 8 dogs, i.e.
