Treatment of acetabular dysplasia by triple pelvic osteotomy and its short-term results

Year 2007, Volume: 41 Issue: 5, 355 - 366, 02.01.2008

Abstract

Objectives: We evaluated the effect of triple pelvic osteotomy on acetabular coverage and its clinical implications by clinical and radiographic parameters in patients with acetabular dysplasia.
Methods: Triple pelvic osteotomy was performed in 21 hips of 19 patients (13 females, 6 males; mean age during operation 16.3 years; range 8 to 32 years). Acetabular dysplasia was bilateral in two, and unilateral in 17 patients. Etiology was developmental dysplasia of the hip in 12 patients, Legg-Calve-Perthes disease in five patients, and diplegic and quadriplegic cerebral palsy in two patients, respectively. The patients were clinically evaluated by the modified Merle d’Aubigne-Postel system, and radiographical assessments were made using nine parameters. The mean follow-up period was 27.7 months (range 14 to 60 months).
Results: According to the modified Merle d’Aubigne-Postel system, preoperative and postoperative clinical scores were 13.14 and 15.29, respectively (p<0.001). The Trendelenburg test was positive in all (94.7%) but one patient preoperatively. At final follow-up, it was positive in six hips (28.6%), delayed positive in 12 hips (57.1%), and negative in three hips (14.3%). Of radiographical parameters, the mean corrections obtained in the center-edge angle, femoral head coverage, acetabular angle, and acetabular index angle were 21.6° (p<0.05), 18% (p<0.05), 14.5° (p<0.05), and 16.4° (p<0.05), respectively, with an increase in lateralization (1.7 mm; p<0.05) and a decrease in cranialization (3.8 mm; p>0.05). The ratio of acetabular depth to width remained unchanged (p>0.05).
Conclusion: Triple pelvic osteotomy is successful in correcting biomechanics of the hip joint in most of the patients with acetabular dysplasia.

Asetabuler displazinin üçlü pelvik osteotomi ile tedavisi ve erken dönem sonuçları

Abstract

Amaç: Asetabuler displazili hastalara uygulanan üçlü pelvik osteotomi ameliyatının asetabuler örtünme üzerine etkisi ve klinik yansıması klinik ve radyografik parametrelerle değerlendirildi.
Çalışma planı: Asetabuler displazisi olan 19 hastanın (13 kadın, 6 erkek; ameliyat tarihinde ort. yaş 16.3; dağılım 8-32) 21 kalçasına üçlü pelvik osteotomi yapıldı. İki hastada iki taraflı, 17 hastada tek taraflı tutulum vardı. Etyoloji, 12 hastada gelişimsel kalça displazisi, beş hastada Legg-Calve-Perthes hastalığı, iki hastada ise biri diplejik diğeri kuadriplejik tutulumlu serebral felçti. Klinik değerlendirme modifiye Merle d’Aubigne-Postel sistemine göre yapıldı. Radyografik değerlendirmede dokuz parametre kullanıldı. Ameliyat sonrası takip süresi ortalama 27.7 ay (dağılım 14-60 ay) idi.
Sonuçlar: Modifiye Merle d’Aubigne-Postel klinik değerlendirme toplam puanları ameliyat öncesi ve sonrasında sırasıyla 13.14 ve 15.29 bulundu (p<0.001).Trendelenburg testi ameliyat öncesinde biri hariç tüm hastalarda (%94.7) erken pozitif iken, son kontrollerde altı kalçada (%28.6) erken pozitif, 12 kalçada (%57.1) geç pozitif, üç kalçada (%14.3) negatif bulundu. Son kontrollerde ameliyat öncesine göre radyografik parametrelerden merkez kenar açısında ortalama 21.6° düzelme (p<0.05), femur başı örtünme oranında %18 düzelme (p<0.05), asetabuler açıda 14.5° düzelme (p<0.05), asetabuler indeks açısında 16.4° düzelme (p<0.05), lateralizasyonda 1.7 mm artma (p<0.05), kranializasyonda 3.8 mm azalma (p>0.05) saptandı. Asetabuler derinlik/genişlik oranı ameliyat öncesi döneme göre farklılık göstermedi (p>0.05).
Çıkarımlar: Üçlü pelvik osteotomi kalça ekleminin biyomekaniğini düzelterek asetabuler displazili hastaların büyük çoğunluğunda başarılı olmaktadır.
