Bony atrophy after mega total hip replacement for bone tumors. 11 cases followed for 3-15 years.
We followed 11 patients 3-15 years after a cemented mega total hip replacement for a proximal femoral bone tumor. 7/8 survivors had good function and only occasional pain. 1 hip had been revised because of deep infection and in 1 case the cup had been exchanged because of aseptic loosening. 2 patients had been operated on because of local recurrence of the tumor. At follow-up, 1 patient had radiographic signs of loosening of the stem after 7 years. There was in 8 cases a pronounced athropy of the femoral cortical bone, not correlated to loosening of the stem.
