Two extensive giant-cell tumours of the proximal humerus treated by resection-reconstruction or...

Giant-cell tumours of bone occur infrequently. Recurrence is often observed following excochleation. Due to the fact that most of these tumours are located in the epiphysis of long bones, treatment of extensive tumours with preservation of joint function usually is troublesome. Two patients are presented: one underwent resection and implantation of an endoprosthesis, the other one excochleation in combination with cryosurgery.
