Kalça protezinde gevşeme ve periprostetik osteoliz

Özet

Ağrısı süren veya yeni başlayan kalça protezli hastada femoral stem çevresindeki kemik kaybı, implant parçacıklarına bağlı osteolizden ya da enfeksiyondan kaynaklanabilir. Metal artefakt azaltmalı kontrastsız BT, stem-kemik ara yüzünü ve radyografide üst üste binen kemik alanlarını kesitsel olarak gösterir. Gevşeme tanısı tek bir radyolüsent çizgiyle konmaz; seri incelemede artan kemik kaybı veya komponent konum değişikliği daha anlamlıdır. İlerleyen osteolizin ve kemik stoğu kaybının atlanması, stem desteğinin bozulmasını ve periprostetik kırık olasılığını gözden kaçırabilir.

Faz ve pencere

Kontrastsız tanısal

Metal artefakt azaltımlı kemik rekonstrüksiyonunda femoral stem boyunca kemik kaybının yerini, korteks ve çimento mantosunun bütünlüğünü, ara yüz ayrışmasını ve stemin önceki incelemeye göre yer değiştirip değiştirmediğini incele; bu kemik-implant değerlendirmesi için intravenöz kontrast gerekmez.

Önerilen pencereler: Kemik (G 1800 / M 400), Yumuşak doku (G 400 / M 40).

BT bulguları

• Periprostetik osteoliz — stem çevresinde sınırları seçilen endosteal kemik kaybı, komşu korteksi inceltebilir veya kemik stoğunda defekt oluşturabilir.
• Ara yüz radyolüsensisi — kemik-stem ya da kemik-çimento sınırını izleyen saydam bant; tek kesitteki görünümü gevşemeyi kanıtlamaz.
• Seri kemik kaybı — önceki BT ile karşılaştırıldığında aynı stem bölgesindeki defektin genişlemesi veya yeni bir bölgeye uzanması.
• Stem migrasyonu — implantın önceki incelemeye göre aşağı yer değiştirmesi, ekseninin değişmesi ya da proksimal femura göre yeni açılanması.
• Çimento mantosu ayrışması — çimentolu stemde çimento boyunca çatlak, parçalanma veya çimento-kemik temasının kaybı.
• Kortikal incelme — osteolitik alanın femur korteksini zayıflatması; özellikle büyük trokanter ve diafiz çevresinde kalan kemik stoğunu haritala.
• Enfeksiyon lehine kemik-yumuşak doku eşliği — düzensiz endosteal yıkımın periostal reaksiyon, koleksiyon veya sinüs yolu ile birlikte bulunması.

Ölçütler ve sınıflamalar

Gruen femoral zonları

Femoral stem çevresindeki kemik, ön-arka radyografide proksimal lateralden başlayıp distale ve medial tarafa devam eden yedi bölgeyle tariflenir; osteolizin konumunu standartlaştırır, BT'de ise kesitsel yer ve uzanım ayrıca belirtilmelidir.

Normalde

Stabil protezli kalçada femoral stemin ekseni ve ucu seri görüntülerde aynı konumdadır; stem çevresindeki korteks süreklidir ve yeni genişleyen kemik defekti yoktur. Mevcut ara yüzü önceki incelemeyle karşılaştır; ilerleme, morfoloji ve komponent göçünü birlikte değerlendir.

Ayırıcı tanı

Protez çevresi enfeksiyon

kemik yıkımına periostal reaksiyon, koleksiyon veya sinüs traktı eşlik edebilir; osteoliz tek başına ayrım yaptırmaz.

Yük aktarımına bağlı kemik yeniden şekillenmesi (stress shielding), zamanla proksimal kemik stoğunda azalmaya yol açabilir.

Metal artefaktı periprostetik değerlendirmeyi kısıtlayabilir; artefakt azaltma yöntemleri metal artefaktını tamamen ortadan kaldırmayabilir.

Periprostetik kırık, protez çevresindeki kemik kaybı ve gevşemeden ayrı bir komplikasyon olasılığıdır; görüntülemede kırık varlığı ayrıca değerlendirilmelidir.

Advers lokal doku reaksiyonu

metal aşınma ürünlerine bağlı gelişen kitle benzeri yumuşak doku (pseudotümör) protez çevresinde kemik kaybına ve gevşemeye eşlik edebilir; modüler femoral stem tasarımları risk faktörü olup yumuşak dokunun gösterilmesinde metal artefakt azaltımlı MR öne çıkar.

Tuzaklar

• Tek incelemede görülen radyolüsent hattı gevşeme diye adlandırma; önce implantın ilk ve ara dönem görüntülerindeki konumunu kıyasla.
• Proksimal femurdaki düzgün kemik incelmesini otomatik olarak osteoliz sayma; stem çevresindeki fokal sınır, korteks defekti ve dağılımı araştır.
• Metal artefaktlarının periprostetik değerlendirmeyi kısıtlayabileceğini göz önünde bulundur; artefakt azaltma teknikleri görüntüyü iyileştirse de artefaktı tamamen ortadan kaldırmayabilir.
• Aseptik gevşeme ile enfeksiyöz gevşemeyi yalnız BT görünümünden kesin ayırma; yumuşak doku yayılımı ve klinik-laboratuvar verileri ile korelasyon gerekir.

Kendini dene

1. BT'de 2 mm'den büyük periprostetik radyolüsensi hangi olasılığı düşündürür?

   • Protez gevşemesi
   • Protez çıkığı
   • Heterotopik ossifikasyon
   • Periprostetik kırık
   Cevabı göster

   Protez gevşemesi. BT'de 2 mm'den büyük periprostetik radyolüsensi olası gevşemeyi düşündürür; değerlendirmede zaman içindeki ilerleme, morfoloji ve komponent göçü de dikkate alınır.

2. Protez çevresindeki kemik yıkımına periostal reaksiyon ve çevresel kontrastlanan sıvı koleksiyonu eşlik ediyor. Öncelikle hangi olasılık araştırılmalıdır?

   • Aseptik gevşeme
   • Protez çevresi enfeksiyon
   • Periprostetik kırık
   • Heterotopik ossifikasyon
   Cevabı göster

   Protez çevresi enfeksiyon. Periostal reaksiyon ve çevresel kontrastlanan protez çevresi sıvı koleksiyonu enfeksiyon olasılığının araştırılmasını destekler; BT bulguları tek başına enfeksiyonu doğrulamaz.
