Özet
Çalışma, terapötik ultrasonun kırık iyileşmesi üzerine etkisini, fiziksel, radyolojik ve mikroskobik olarak belirlemek amacıyla yapıldı. Araştırma toplam 48 adet sağlıklı tavşan üzerinde dört grup halinde gerçekleştirildi. Tüm hayvanlara bilateral fibular osteotomi yapıldı. Operasyondan sonraki günden başlamak üzere, hayvanların sol fibulaları üzerine, gruplara göre sıra ile 02, 0.5, 1 ve 1.5 Watt/cm2 yoğunluğunda pulzatif ultrason uygulandı. Uygulama, 10 gün boyunca günde 10 dakikalık seanslar halinde yapıldı. Kontrol grubu olarak kullanılan sağ fibulalar üzerine ise aynı sürelerde ultrason cihazı çalıştırılmaksızın sadece prob friksiyonu uygulandı. Araştırmanın 0.7,15,21 ve30. günlerinde sağ ve sol fibulaların radyografisi alındı. Bir ay sonunda tavşanlara ötenazi yapılarak sağ ve sol fibulaları alındı. Her gruptaki ikişer çift fibula'nın histolojik muayenesi yapıldı. Diğer numunelerde kallus büyüklükler, medio-lateral ve aaterio-posterior eksenlerden, kompas ile ölçüldü. Aynı numunelerde basma ve çekme deneyleri yapılarak kallus mukavemeti değerlendirildi.
The effect of ultrasound therapy on fresh fracture healing was investigated experimentally in this study by physical, radiological and microscopical findings. Complete bilateral transverse fibular osteotomies were made in 48 rabbits. The rabbits were divided into four groups and while the left fibular fractures were treated with pulsed ultasound in an intensity of 0.2,0.5 and 1.5 Watt/cm2 respectiveliy, the mock-irradiated right limbs served as untreated controls. Ultrasoundtherapy was started the day after the operation and continued for ten days in periods of ten minutes daily. The right and left fibular osteotomies were evaluated radiologically just after the operation and in the 7 th, 15 th, 21 st and 30 th days. After the last radiologic controls, animals were euthanasied and right and left fibulae were collected. While the two pairs of fibulae from each group were evaluated histologically, callus sizes of other samples were measured from medio-lateral and anterio-posterior axises. The biomechanical properties of the callus was evaluated by testing the compression and tensile forces of the samples. It was concluded that fresh fracture healing was accelerated by ultrasound application in an intesity of 0.2 and 0.5 Watt/cm2 than 1 and 1.5 Watt/cm2 by the physical, radiological and microscopical findigs.
