Iwai T, Hoshi M, Oebisu N, et al. - Researchers investigated whether finite element analysis (FEA) offers beneficial thresholds for bone biopsy practice patterns. Rabbit femurs were used to conduct femoral head compression test, employing FEA to detect the part of the bone that preferentially fractures (n = 15/group). Using finite element models, four types of rectangular biopsy holes were made. A good correlation of FEA results with those of the femoral head compression test was found in this study. A width < 10% of the circumference length in bone biopsy holes aided in minimizing bone strength reduction employing FEA. To prevent pathological fractures following bone tumor biopsy, conducting FEA by orthopedic doctors may be beneficial.
