[Microsurgical treatment of bone and joint defects of hand]

From 1972 to 1990 seven kinds of microsurgical operations were used for treatment of bone and joint defects of hand. Among these cases 23 survived and 1 failed. The patients were followed up for 2-20 years. The functional results were good in 77.4%. The improved surgical procedures: (1) Use dorsalis pedis artery as the single pedicle to provide double vascular supply for double joint graft from one toe. (2) Change the fixing position of metatarsal to increase the degree of motion of the joint. The operative indications and the factors related to the survival and function are discussed.
