Abstract

OBJECTIVE: Scoliosis is a 3-dimensional deformity. Today, the use of orthesis for medium and light degree of deformities is one of the most widely applied treatment models. There are many question marks regarding the application of the best orthesis. The use and effectiveness of orthesis has still been discussed. Today, with industrial new generation orthesis in addition to the developments in CAD/CAM and computerized biomechanical simulation technologies, the treatment of deformity has become possible by providing optimal biomechanical efficiency. The aim of this study is to compare effectiveness of two different orthesis design technique in conservative treatment of adolescent idiopathic scoliosis.METHODS: The study included 28 patients with scoliosis 22 females and 6 males,mean age 15.8 whose follow-up was retrospectively complete for the study. Patients were divided into 2 groups. The first group: It was consisted of 16 patients who were treated with TLSO type prepared by using the standard design methods. Second group: It was consisted of 12 patients for whom orthesis which were carried out with 3-dimensional finite element model as biomechanics of the individual geometry in design and production process and CAD/CAM software Rodin4® were used. At the beginning and sixth month follow-up of patients,their Cobb's angles were measured by taking a standing x-ray of them with long cassette.RESULTS: There was no significant difference between the two groups regarding the age and gender p>0.05 . At the end of six months,while improvements at Cobb's angle in thoracic-lumbar deviousness in the first group were 18%-22%,in the second group,they were observed as 29%-42% p

Ortez Dizaynında Biyomekanik Simulasyon ve Standart Tekniğin Adolesan İdiyopatik Skolyoz Tedavisindeki Etkilerinin Karşılaştırılması: İlk Sonuçlar

Abstract

AMAÇ: Skolyoz 3 boyutlu bir deformitesidir. Orta ve hafif dereceli deformitelerde ortez kullanımı günümüzde en yaygın uygulanan tedavi modellerinden biridir. Ortezin kullanım ve etkinliği hala tartışılmaktadır. Günümüzde CAD /CAM ve bilgisayarlı biyomekanik simulasyon teknolojilerindeki gelişmelerle birlikte endüstriyel yeni jenerasyon ortezlerle deformitenin optimal biyomekanik etkinlik sağlanarak tedavisine olanak sağlanmıştır. Bu çalışmanın amacı adolesan idiyopatik skolyozon konservatif tedavisinde 2 farklı ortez dizayn tekniğinin etkinliklerinin karşılaştırılmasıdır.YÖNTEMLER: Çalışmaya retrospektif olarak takipleri eksiksiz olan 28 22 kadın, 6 erkek, ortalama yaş 15.8 skolyozlu hasta dahil edildi. Hastalar 2 gruba ayrıldı. Birinci grup: Standart dizayn yöntemleri kullanılarak hazırlanan TLSO tipi kullanarak tedavi edilen 16 hastadan oluştu. İkinci grup: diazyn ve üretim aşamasının bireysel geometrinin biyomekanik olarak 3 boyutlu sonlu elemanlar modeli ve CAD/CAM yazılımları Rodin4® ile gerçekleştirildiği ortezleri kullanılan 12 hastadan oluştu. Hastaların başlangıç ve 6. ay takiplerinde uzun kaset ayakta röntgenleri çekilerek cobb’s açıları ölçüldü.BULGULAR: Her iki grup arasında yaş ve cinsiyet açısından fark izlenmedi p>0,05 . Altı ay sonunda Birinci grupta torakal-lomber eğriliklerdeki cobb’s açısındaki düzelmeler 18%-22% iken, İkinci grupta 29%-42% p
