Abstract

Objectives: Clinically, the Z-plasty lengthening is the only method used in the upper extremity, whereas several different techniques such as the Vulpius and Baker are used in the lower extremity. In this study, the usage of the modified Vulpius and Baker tendon lengthening techniques in the upper extremity was investigated. Materials and methods: Vulpius and Baker techniques are modified by changing their application site in 90 sheep fore-limb deep flexor tendons using three randomly divided groups. Z-plasty, V-Y-plasty (Modified Vulpius) and U-T-plasty (Modified Baker) techniques were used in groups I to III, respectively. Their elongation and biomechanical properties were compared. Results: The Z-plasty technique provided significantly greater lengthening than the other two techniques, followed by the U-T-plasty technique. Failure load of the U-T-plasty technique was 60.7% higher than the Z-plasty technique and 45.4% higher than the V-Y-plasty technique. Repairs with the U-T-plasty and V-Y-plasty techniques were significantly stiffer than the repairs with the Z-plasty technique. Conclusion: The U-T-plasty technique may be a good alternative to the Z-plasty technique because of its easy application and better biomechanical properties, especially in cases that need moderate-sized elongation and early mobilization. But the restorative properties of this technique need to be observed on an in-vivo model.

Özet

Amaç: Klinikte üst ekstremitede tendon uzatma yöntemi olarak özellikle Z-plasti uygulanırken, alt ekstremitede bu amaçla Vulpius ve Baker gibi çok sayıda farklı yöntemler uygulanmaktadır. Bu çalışmada Vulpius ve Baker yöntemleri geliştirilerek üst ekstremitede denendi. Gereç ve yöntemler: Vulpius ve Baker yöntemleri uygulama yerleri değiştirilmek suretiyle geliştirilerek 90 adet koyun ön ayak derin fleksor tendonunda çalışıldı. Tendonlar rastlantısal olarak üç eşit gruba ayrıldı. Birinci gruba Z-plasti, ikinci gruba V-Y-plasti (Modifiye Vulpius), üçüncü gruba U-T-plasti (Modifiye Baker) yöntemiyle uzatma uygulandı. Uzama miktarları ve biyomekanik dayanımları değerlendirildi. Bulgular: Z-plasti yöntemi her iki yöntemden de anlamlı derecede daha fazla uzatma sağladı. U-T-plasti yöntemi bu yöntemi izledi. U-T-plasti yönteminin Z-plasti yönteminden %60.7 ve V-Y-plasti yönteminden %45.4 daha fazla yük taşıdığı bulundu. U-T-plasti ve V-Y-plasti teknikleri ile gerçekleştirilen onarımlar Z-plasti ile yapılan onarımlardan anlamlı derecede daha sertti. Sonuç: Özellikle orta derecede uzatma ve erken mobilize olmayı gerektiren olgularda U-T-plasti yöntemi, kolay uygulanabilirliği ve daha üstün biyomekanik özellikleri nedeniyle Z-plasti yöntemine alternatif olabilir. Ancak bu yöntemin iyileşme özellikleri bir in-vivo modelde araştırılmalıdır.
