Fig. 2From: Mid- to long-term results of modified non-vascularized allogeneic fibula grafting combined with core decompression and bone grafting for early femoral head necrosisThe radiographic outcomes of a 36-year-old man with a long history of drinking and was diagnosed as left femoral head necrosis at Ficat II stage. A1–A5 The patient has early femoral head necrosis evaluated by X film and MRI respectively. B1–B3 The X film of 3 days after the operation. It shows that the femoral head is in normal shape and the grafted fibula integrates tightly in the channel. C, D The images at 1 and 4 months after the operation, respectively. E1–E3 The images at 2 years after the operation. F1–F3 The images at 5 years after the operation, which shows the stability of the articular cartilage and femoral head. G1–G3 The images at 8.2 years after the operation. The femoral head is not progressed and keeps in good shape. The left femoral head was in Ficat I stage and the Harris score was 90 at the last follow-upBack to article page
