Fig. 6From: Biomechanical analysis of fibular graft techniques for nontraumatic osteonecrosis of the femoral head: a finite element analysisThe reduction in the average von Mises stresses following the CTT/LBT in the JIC C1 and C2 groups. CTT, core track technique; LBT, light bulb technique; WB, weight-bearing area; CFH, central femoral head; FH, femoral neck; TS, trochanteric and subtrochanteric region.Back to article page
