Impact of Femoral Neck Cortical Bone Defect Induced by Core Decompression on Postoperative Stability: A Finite Element Analysis

Figure 4

Construction of different core decompression models (yellow: cortical bone, blue: cancellous bone, red: necrotic area, green: bone defect): (a) standard operating model without cortical bone injury; (b) femoral neck (anterior) defect with cortical bone injury; (c) femoral neck (posterior) defect with cortical bone injury; (d) size of the bone defect; (e) femoral neck (superior) defect with cortical bone injury; (f) femoral neck (inferior) defect with cortical bone injury.
