Özet

Giriş: Hemiartroplasti uygulanan hastalarda asetabular erozyon geç dönemde görülen önemli bir komplikasyondur. Bu çalışmanın amacı proksimal femur kırığı nedeniyle bipolar hemiartroplasti uygulanan hastalarda asetabular erozyona sebep olan risk faktörlerini değerlendirmektir. Yöntemler: Tek merkezli retrospektif çalışmada Ocak 2017–Kasım 2023 arasında proksimal femur kırığı nedeniyle bipolar hemiartroplasti uygulanan, ≥55 yaş, en az 2 yıllık radyolojik takibi bulunan 126 hasta değerlendirildi. Demografik veriler, femoral stem tipi ve bipolar femoral baş çapı kaydedildi. Erken postoperatif ön-arka pelvis grafilerinden bacak uzunluk farkı ve femoral offset farkı ölçüldü. Asetabular erozyon, son kontrol grafilerinde Baker sınıflamasına göre derecelendirildi. İstatistiksel analizler için t testi, Mann–Whitney U, ki-kare testi ve Spearman korelasyon analizi kullanıldı. Bulgular: Hastaların ortalama yaşı 78,10±7,66 yıl, %74,6’sı kadındı ve ortalama takip süresi 38,67±12,45 aydı. Baker sınıflamasına göre hastaların %29,4’ünde grade 0, %42,9’unda grade 1, %18,3’ünde grade 2 ve %9,5’inde grade 3 erozyon mevcuttu. Kadın cinsiyette asetabular erozyonun anlamlı olarak daha sık görüldüğü saptandı (p=0,025). Femoral baş çapı ≤48 mm olan hastalarda asetabular erozyon riskinin artmış olduğu görüldü (p=0,043; OR=3,10; %95 GA: 1,00–9,66). Takip süresinin uzaması ile asetabular erozyon derecesindeki artış arasında anlamlı bir ilişki mevcuttu (p=0,001). Yaş, femoral stem tipi, bacak uzunluk farkı, femoral offset farkı ve T skoru ile asetabular erozyon arasında anlamlı ilişki saptanmadı. Sonuç: Hemiartroplasti sonrası asetabular erozyon gelişiminde kadın cinsiyet ve bipolar femoral baş çapının ≤48 mm olması başlıca risk faktörleri olarak öne çıkmaktadır. Cerrahi karar verme sırasında kadın cinsiyet ve küçük femoral baş kullanımı gibi risk faktörlerinin dikkatle değerlendirilmesi gerekmektedir.

Abstract

Introduction: Acetabular erosion is a significant, late-stage complication in patients undergoing hemiarthroplasty. This study aimed to investigate the risk factors for acetabular erosion in patients undergoing bipolar hemiarthroplasty for proximal femoral fractures. Methods: This single-center retrospective study was performed on 126 patients aged between 55-85 years who underwent bipolar hemiarthroplasty for proximal femoral fractures between January 2017 and November 2023 and had at least 2 years of radiological follow-up. The demographic data, femoral stem type, and bipolar femoral head diameter of patients were recorded. Femoral offset (FO) and leg length discrepancy (LLD) were measured from early postoperative anteroposterior pelvic radiographs. Acetabular erosion was graded based on the Baker classification on final follow-up radiographs. Statistical analyses were performed using the t test, Mann–Whitney U test, chi-square test, and Spearman correlation analysis. Results: The mean age of patients was 78.10 ± 7.66 years. 74.6% were female, and the mean follow-up period was 38.67 ± 12.45 months. According to the Baker classification, 29.4% of patients had grade 0, 42.9% had grade 1, 18.3% had grade 2, and 9.5% had grade 3 erosion. Acetabular erosion was found to be significantly more common in female patients (p = 0.025). An increased risk of acetabular erosion was observed in patients with a femoral head diameter ≤48 mm (p = 0.043; odds ratio = 3.10; 95% confidence interval = 1.00–9.66). A significant correlation was noted between increased follow-up duration and increased degree of acetabular erosion (p = 0.001). No significant correlation was found between age, femoral stem type, LLD, FO discrepancy, osteoporosis grades (T-score), and acetabular erosion. Conclusion: Female sex and a bipolar femoral head diameter ≤48 mm were the main risk factors for the development of acetabular erosion after hemiarthroplasty and should be considered in surgical decision-making.
