Comparison of the effects of phonophoresis and ultrasound therapy on recovery of experimental tenorrhaphy in rabbits

Abstract

Tendon ruptures occur generally at distal portions of extremities and require relatively long recovery period. Traumatic ruptures of Achilles tendon need 6-8 weeks of immobility period including pre and postoperative days. In order to avoid other orthopedical problems by this application and to speed up the recovery period, postoperative local administrations are done. Therapeutic Ultrasound (TUS) is one of these applications. Phonophoresis is the local absorbing procedure of some drugs by means of TUS which is applied to the affected area. Forty male New Zealand rabbits were used in the study which were one year old and mean 3 kg body-weight. The rabbits were divided into 4 groups and experimental Achilles tendon rupture was created in both legs of all rabbits and repaired immediately by tenorrhaphy. The right legs of rabbits of groups 1 and 3 were treated postoperatively with TUS for 10 days. The right legs of rabbits in groups 2 and 4 were treated postoperatively with phonophoresis for 10 days. Left legs of all rabbits served as the control group. All rabbits were euthanized at the end of the 30th day. Samples which were taken from groups 1 and 2 were examined histopathologically and those in groups 3 and 4 were examined biomechanically. In biomechanical investigations, the rupture points of the tendons in N (Newton) were compared. At the end of the study, it was concluded that TUS is a superior for tendon healing when compared to phonophoresis

Deneysel olarak tenorafi yapılan tavşanlarda ultrason terapi ile fonoforezisin iyileşme üzerineetkilerinin karşılaştırılması

Abstract

Tendo kopukları çoğunlukla ekstremitelerin distal kısımlarında meydana gelmekte ve uzun süreli bir iyileşme periyodu gerektirmektedir. Travmatik aşil tendo kopuklarında operasyon öncesi ve sonrasını da kapsayan 6-8 haftalık bir bandaj uygulaması ile hareketsizlik sağlanmaktadır. Bu uygulamanın neden olacağı diğer ortopedik problemleri önlemek ve iyileşme periyodunu hızlandırabilmek amacıyla, operasyon sonrası lokal uygulamalar yapılmaktadır. Ultrason terapi (TUS) bunlardan biridir. Fonoforezis ise emilim özelliği olan ilaçların TUS eşliğinde lokal olarak bölgeye emdirilmesidir. Deneysel çalışmamızda 40 adet erkek, 1 yaşında, ortalama 3 kg ağırlığında, Yeni Zelanda tavşanı kullanıldı. Tavşanlar 4 gruba ayrıldı ve tüm tavşanların her iki arka bacağında deneysel Aşil tendo rupturu oluşturuldu ve hemen akabinde tenorafi ile onarıldı. Birinci ve üçüncü gruptaki tavşanların sağ bacaklarına operasyondan sonraki 10 gün boyunca ultrason terapi uygulandı. İkinci ve dördüncü gruptaki tavşanların sağ bacaklarına ise operasyondan sonraki 10 gün boyunca fonoforez uygulandı. Tüm çalışma gruplarında, sol bacaklar kontrol grubunu oluşturdu. Tavşanlar 30. gün sonunda ötenazi edilerek grup 1 ve 2’deki örnekler histopatolojik olarak, grup 3 ve 4’teki örnekler ise biyomekanik olarak incelendi. Biyomekanik inceleme için tendoların kopma noktaları N (Newton) cinsinden karşılaştırıldı. Çalışmanın sonucunda; ultrason terapinin fonoforezle karşılaştırıldığında tendo iyileşmesi için daha üstün bir metod olduğu kanısına varıldı
