Triple Osteotomy Of The Pelvis For Acetabular Dysplasia: Results At 8 To 15 Years

Abstract

Reorientation of the acetabulum may be required in adolescents and young adults with developmental dysplasia of the hip. We have carried out a retrospective 5,6 results of these procedures/' Although most authors argue that they reduce the risk of secondary degenerative arthri tis,7 this has never been demonstrated in clinical studies.review of 51 hips after triple osteotomy with an average We have reviewed 51 hips at between 8 and 15 years after follow-up of ten years (8 to 15). Forty-eight hips (94%) were available for review and of these 39 (81%) were improved compared with before operation, 29 (60%) scoring good or excellent. Radiographic assessment showed improvement of the average centre-edge angle by 19°, the acetabular index by 12° and the anterior triple osteotomy. We have previously described the results after four years.8 PATIENTS AND METHODSBetween 1980 and 1987 we carried out 51 triple acetabular centre-edge angle by 26°. The degree of osteoarthritis osteotomies on 43 patients. There were 38 females and 5 progressed by one grade in ten hips (21%) over a period males; the mean age at operation was 28 years (14 to 46). of ten years.

Impingement Adversely Affects 10-year Survivorship After Periacetabular Osteotomy for DDH

“…4). Compared with the literature, Group I in the current study showed a superior survivorship rate of 90% at 10 years followup (Table 5) [5,11,17,21,26,33,44,48]. Reported survivorship rates for PAO ranged from 54% to 85% [11,17,21,33].…”

“…Reported survivorship rates for PAO ranged from 54% to 85% [11,17,21,33]. For triple and Chiari osteotomies, the reported survival rates at 10 years followup were 73% and 84%, respectively (Table 5) [5,26]. The survivorship rate in our Group II, including hips with morphologic features predisposing to FAI, was 78% and was at the lower range of the reported rates in the literature (Table 5).…”

Can a Triple Pelvic Osteotomy for Adult Symptomatic Hip Dysplasia Provide Relief of Symptoms for 25 Years?

“…We present a series of patients with a followup of 96% at 23 to 29 years after pelvic osteotomies. This study is a followup study after previous reports on the 8-to 15-year follow-up and a 15-year followup of triple osteotomies of the pelvis [5,22]. The purposes of this study therefore were to determine whether the triple osteotomy can provide (1) continuing pain relief and (2) function; and to determine the (3) incidence of OA and (4) number of patients undergoing THA 23 years or more after triple osteotomy.…”

“…The operative technique has been described previously [5,11]. The operation began with a separate posterior approach for the osteotomy of the ischium.…”

“…Other treatment modalities are the Chiari osteotomy and shelfplasty [18]. We have used a triple osteotomy since 1980 and followup studies of 10 and 15 years have been published [5,11,22]. These reports show a Merle d'Aubigné-Postel score of 15 to 18 points (''good'' to ''excellent'') in 56% of all patients with little progression of osteoarthritis (OA) and only six patients (12%) underwent a THA by 15 Dungl et al [7] described Merle d'Aubigné-Postel scores of 18 in 40% and of 15 to 17 in 32% of patients with 146 triple osteotomies.…”
