Comparison of femoral measurements between this study and other published data.

NSA: neck-shaft angle, FHD: diameter of the femoral head, MLD+20 and APD+20: medial-lateral diameter and antero-posterior diameter of bone medullary cavity at a plane of 20 mm above the lesser trochanter, MLD and APD: medial-lateral diameter and antero-posterior diameter of bone medullary cavity at the midpoint of the lesser trochanter, MLD−20 and APD−20: medial-lateral diameter and antero-posterior diameter of bone medullary cavity at a plane of 20 mm below the lesser trochanter, IID: internal diameter of the isthmus, IED: external diameter of the isthmus, IP: distance from the midpoint of the lesser trochanter to the isthmus. CFI: Canal flare index.*Significantly different compared with our study (PNR: not reported.
