A and B. Coronal and sagittal computed tomography slices obtained at the time of bone biopsy, taken from the lateral femoral cortical at 9 months of follow-up depicting no evidence of stem loosening or sinking. C and D. 10x and 40x haematoxylin and eosin staining histological sections taken from a bone biopsy taken at the lateral femoral cortical of the patient's left hip at 9 months of follow-up. Pathology analysis reveals disorganized trabecular bone and cartilaginous tissue with peri-haversian bone formation areas and abundant capillaries (angiogenesis), as well as increased subperiosteal osteoblastic activity.
