Abstract
Evaluation of bone graft viability for acetabular reconstruction was investigated with single photon emission computed tomography (SPECT).
SPECT was helpful in producing anatomic reconstruction of the acetabulum and in evaluating viability of acetabular bone grafts.
Data were corrected with reference to sacral activity for the purpose of comparing with serial SPECT. There was a slight aberration in correction of this method when the corrected data were confirmed using the activity of the opposite anterior superior iliac apine. However the aberration was less than 10% of the activity.
Progress of incorporation and revascularization of the graft might be able to be assessed using serial standardized SPECT, and this information may be useful in preventing graft migration.
