Proximal Femoral Allograft for Major Segmental Femoral Bone Loss: A Systematic Literature Review

Table 2

Surgical techniques used including approach, the type of femoral osteotomy performed at the host bone-allograft junction, and whether the host proximal femur was resected or split and used as an onlay graft. NR: not reported. Study numbers correlate with Table 1.
