Revascularization of avascular spongy bone and head of the femur in transplantation of vascular bundle (An experimental and clinical study).
Transplantation of a vascular bundle into an avascular spongiosa replant and the head of the femur after interruption of its blood supply was carried out in experiment (66 experiments on 34 dogs). The periods of observation reached 72 weeks. The mechanisms of revascularization of bones devoid of vessels and the results of morphometric analysis were investigated. It has been established that revascularization of a spongiosa replant sets in after 3 weeks and that of the femoral head after 12-16 weeks. Clinical observations (69 cases) were concerned with transplantation of a vascular bundle in the treatment of patients with aseptic osteonecrosis.
