Fig. 1Schematic diagram showing Doppelt's method. To measure the extent of sliding and greater trochanter latelaization, correction factor was applied. Correction factor=B/b, the extent of sliding=A-a×B/b, the extent of lateral displacement=c-C×B/b.
Fig. 2
(A) Initial radiograph shows the right femoral unstable intertrochanteric fracture of AO type A2.2.
(B) Postoperative radiograph shows the anatomical reduction with good alignment. Fracture site are reduced and stabilized with compressive hip screw.
(C) Final follow up radiograph shows the varus collapse and eventually non-united of fracture site.
Fig. 3
(A) Initial radiograph shows the left femoral unstable intertrochanteric fracture of AO type A2.3.
(B) Postoperative radiograph shows the anatomical reduction with good alignment. Fracture site are reduced and stabilized with compressive hip screw and additional trochanteric stabilizing plate.
(C) Final follow up radiograph shows the impaction of fracture site and complete union.
