ÖN ÇAPRAZ BAĞ REKONSTRÜKSİYONU SONRASI DÖNEMDE OLUŞAN TÜNEL GENİŞLİĞİNİN ÖLÇÜM METODUNDA MANYETİK REZONANS GÖRÜNTÜLEME VE BİLGİSAYARLI TOMOGRAFİ'NİN KARŞILAŞTIRMALI GÜVENİLİRLİK ANALİZİ

AMAÇ: Ön çapraz bağ (ÖÇB) cerrahisi sonrası tünel genişlemesi radyolojik olarak farklı tetkikler ile ölçülebilmektedir. Hasta takiplerinde tünel genişlemesinin değerlendirilmesinde bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) tetkikleri kullanılmaktadır. Çalışmamızın amacı; artroskopik ÖÇB tamiri uygulanan hastalarda femoral ve tibial tünel genişliği ölçümünde görüntüleme tetkikleri arasındaki güvenilirliği analiz etmektir. GEREÇ VE YÖNTEMLER: Kliniğimizde hamstring otogrefti kullanılarak asansör sistemi ile izoanatomik artroskopik ÖÇB rekonstrüksiyonu yapılan ve takiplerinde lineer tünel genişlemesi olan 24 hasta çalışmaya dahil edildi. Hastaların BT ve MRG'de aksiyel, koronal ve sagittal planda tünel genişlikleri, 5 gözlemci tarafından ölçüldü. Kesitler üzerinde her gözlemci tarafından femoral ve tibial tüneller için giriş, orta, çıkış genişliği PACS (Picture Archiving and Communication System) sistemi üzerindeki cetvel uygulaması ile ölçüldü. Ölçümler birer hafta arayla tekrarlandı ve bağımsız bir cerrah tarafından kayıt edildi. BULGULAR: Çalışmamızda femur ölçümlerinin tüm kesitlerinde toplam 90 ölçümden MRG'de 14, BT'de 11 anlamlı fark görüldü (p

RELIABILITY ANALYSIS OF MAGNETIC RESONANCE IMAGING AND COMPUTERIZED TOMOGRAPHY IN THE MEASUREMENT OF TUNNEL WIDTH AFTER ANTERIOR CRUCIATE LIGAMENT REPAIR

OBJECTIVE: Tunnel widening following anterior cruciate ligament (ACL) surgery can be measured by several radiological methods. Computed tomography (CT) and magnetic resonance imaging (MRI) are used to evaluate tunnel widening. The aim of our study is to analyse the reliability of tunnel width measuring between two different radiographic methods.MATERIAL AND METHODS: 24 patients who underwent isoanatomic arthroscopic anterior cruciate ligament reconstruction using hamstring autograft with elevator system in our clinic and had linear tunnel widening in their follow-up were included in the study. Five observers measured the tunnel width on sagittal, coronal and axial images of CT and MRI of the patients. Aperture, mid-section and exit width for the femoral and tibial tunnels were measured by each observer on these sections with a ruler application on the PACS system (Picture Archiving and Communication System). The measurements were repeated with one week interval and the measurements were documented by an independent surgeon.RESULTS: 14 significant differences in MRI measurements and 11 significant differences in CT measurements were seen in a total of 90 femoral measurements in all sections (p
