Rarefied femoral neck trabecular patterns, fracture displacement, and femoral head vitality in femoral neck fractures.

Before operation, 99mTc-MDP scintimetry was performed in 103 patients with femoral neck fractures. There was a significant correlation (r = 0.63, p less than .01) between osteoporosis and fracture displacement, but no correlation (r = 0.07, p greater than .01) between femoral neck trabecular bone patterns and femoral head viability and no correlation (r = 0.11, p less than .01) between fracture displacement and femoral head viability.
