Reconstruction of the bones and joints of the upper extremity by vascularized free fibular graft: report of 46 cases.
The vascularized free fibular graft was applied in reconstructing bone and joint structures of the upper extremity in 46 cases between August, 1977 and December, 1989. Among these, 30 were grafts of the fibular shaft and 16 were grafts of the fibular head. There were 19 bony defects after trauma or osteomyelitis, 18 bony or articular defects after resection of tumors, five congenital deformities or defects, and four replacements for fibrous dysplasia. The longest grafted fibula was 22 cm and the shortest, 5 cm. Thirty-one cases were followed for more than two years, and these were evaluated for functional ability in daily living, roentgenologic appearance, and 99mTc scan during follow-up. The results revealed quite sufficient functional restoration, solid bone healing, and adequate blood supply, in most cases. The vascularized free fibular head graft appears to be an ideal procedure for the reconstruction of defects of the lower end of the radius or the upper humerus, including the humeral head. The stability of the reconstructed wrist or shoulder joint was maintained by suturing the lateral collateral ligament, the palmar collateral ligament around the wrist, or by passing the long head of the biceps brachii through the grafted fibula at the shoulder. Methods for fixation of the fibular shaft to the recipient bone and the selection of vessels for anastomoses, both in the graft and at the recipient site, are discussed. The importance of postoperative functional exercise is emphasized.
