Fig 1.
(A) Schematic diagram showing the technique used for measuring the CCR, CFI, MCI, and CBR. CCR = E/C, CFI = A/E, MCI = B/D, and CBR = E/F, as previously described [10]. (B). Schematic diagram showing the measurement of CFR (mid-third). CFR (mid-third) = S/E, where S is the stem width and E is the endosteal canal width, as previously described [12]. CCR, canal calcar ratio; CFI, canal flare index; MCI, morphologic cortical index; CBR, canal bone ratio; CFR, canal fill rate.

Schematic diagram showing the measurement of biomechanical parameters determined in postoperative radiographs after hemiarthroplasty: 1, abductor lever arm; 2, horizontal femoral offset; 3, limb length; and 4, vertical femoral offset.
A, Horizontal tear drop line; B, midline lesser trochanter; C, tangential line to the greater trochanter; D, femoral shaft axis; and E, stem axis.
