Abstract

We compared the outcomes of 26 intramedullary cemented massive allografts with 19 allografts without cementation; all allografts were used for reconstruction after excision of bone sarcomas. In the cementation group, 12 allografts were used as osteochondral grafts (proximal humerus 4, proximal tibia 4, and distal femur 4), 7 as intercalary diaphyseal allografts of the femur, and 7 for a knee arthrodesis. In the uncemented allografts, 3 allografts were used as osteochondral grafts (proximal humerus 2, proximal tibia 1), 2 as intercalary diaphyseal allograft of the femur, and 14 for a knee arthrodesis. The average length of follow-up was 40 (25-60) months. 14 of 26 cemented allografts had an excellent (osteotomy line: not visible) or good (fusion ≤ 75% of the cortical thickness) healing of the junction site. Infection developed in 1 allograft. Fracture occurred in 4 of 12 cemented osteochondral allografts due to a subchondral collapse (all in the proximal tibia). Fractures at the junction site in the lower extremity developed in 4 of 22 cemented allografts. In 19 allografts without cementation, 11 had excellent or good healing of the junction. Late infection developed in 4 allografts, fracture of the allograft in 3 cases, and junction fracture in 3 of 17 patients with reconstruction of the lower extremity. Intramedullary graft cementation seems to reduce the fracture and infection rates.
