Since 1983, four patients with aggressive giant cell tumor and malignant tumor have undergone an en bloc resection of the tumor and the skeletal reconstruction with a prosthesis and massive bone allograft. In those with malignant tumor, the transfer of the trapezius and the acromion (Bateman) was supplemented following removal of deltoid. The follow-up periods were 9 to 35 months and averaged 21 months. One died of lung metastasis, but there was no recurrence. There was one nonunion. A patient with giant cell tumor had a pain-free shoulder without any difficulty in activity of daily life. Pain-free shoulders with some limitation of daily life activity, especially-active overhead motion were regained in patients with malignant tumor. Although further follow-up periods are required, these observations suggest that the trapezius transfer can, to some extent, substitute for deltoid and that a prosthesis in this procedure is not a passive spacer.
