Table 1 Baseline characteristics of patients came across both VIBG and THA (“VIBG+THA” group) (N = 27) and those with a primary THA (“THA only” group) (N = 242)

From: Osteonecrosis of the hip: is there a difference in the survivorship of total hip arthroplasty with or without previous vascular iliac bone grafting?
