Sažetak

Uvod/Cilj. Koštana modrica predstavlja uobičajen nalaz kod akutne povrede kolena na magnetnoj rezonanci (MR). Cilj rada bio je da se proceni stepen udruženosti koštane modrice (KM) sa posttraumatskim lezijama prednje ukrštene veze (ligamentum cruciatum anterior - LCA) i meniskusa. Koštana modrica je posttraumatska promena koštane srži koja je posledica kombinacije hemoragije, edema i mikrotrabekularne frakture bez prekida kontinuiteta korteksa. Magnetna rezonanca je metoda izbora za prikazivanje koštanih modrica koje se ostalim radiološkim metodama ne mogu prikazati. Metode. Magnetnom rezonancom pregledano je 120 bolesnika sa akutnom traumom kolena. Svi bolesnici pregledani su u prvih mesec dana nakon traume. Pregledi su obavljeni na 0,3T MR aparatu. Rezultati. Posttraumatska KM viđena je kod 39 (32,5%) bolesnika od ukupno 120. Kod tri bolesnika uočeno je prisustvo i frakture korteksa, takozvana okultna fraktura koja nije uočena na radiografiji. Analizirali smo samo čiste koštane modrice bez frakture korteksa. Nalaz KM bio je u kombinaciji sa lezijom LCA kod 27 (69%) bolesnika. Kod 28 (72%) bolesnika KM je bila u kombinaciji sa lezijom meniskusa. Kod dva bolesnika nalaz KM bio je bez patološkog nalaza na LCA i meniskusima. Bez KM bilo je 78 bolesnika, ali njih 33 (43%) imalo je lezije LCA, a 49 (63%) lezije meniskusa. Zaključak. Koštana modrica najbolje se uočava u Short TI Inversion Recovery (STIR) sekvenci i čest je nalaz kod akutne traume kolena. Veoma često je udružena sa posttraumatskim lezijama LCA i meniskusa, pa na njih posebno treba obratiti pažnju pri pregledu sa nalazom KM kolena. Razlika učestalosti lezija unutrašnjih struktura kolena kod bolesnika sa nalazom KM je statistički visokoznačajna u odnosu na bolesnike bez nalaza KM.
