Figure 1
Figure 1 The center-edge angle, acetabular index angle, Sharp angle, acetabular head index, and head lateralization index were evaluated in anteroposterior X-ray images. CE: Center-edge; AHI: Acetabular head index; HLI: Head lateralization index.
Figure 2
Figure 2 Anteroposterior X-ray images of cases 1, 2 and 5. A: Pre-operative anteroposterior (AP) X-ray images of cases 1 and 2 showing pre-osteoarthritis in a patient with bilateral developmental dysplasia of the hip (DDH); B: Post-operative AP X-ray image at the final follow-up examination. Three 3.0 mm K-wires were used for fixation of the acetabulum. One of the K-wire was remained at the right hip; C: Pre-operative AP X-ray image showing pre-osteoarthritis in a patient with bilateral DDH; D: Post-operative AP X-ray image at the final follow-up examination.
Figure 3
Figure 3 Several major modifications of triple osteotomy have been presented, and osteotomy line of the Bernese osteotomy and rotational acetabular osteotomy was also presented. In Steel’s triple osteotomy, the pubic ramus and ischium in front of the tuberosity are osteotomized. The site of the ischial and pubic osteotomy in the method of Tönnis is closer to the acetabulum compared with Steel’s osteotomy. In a Hopf triple osteotomy, the ischial tuberosity is osteotomized closer to the center of the hip joint than in Steel’s procedure. In a Le Coeur osteotomy, the pubis and ischial ramus are osteotomized closer to the pubic symphysis as compared with Steel’s procedure.
