Abstract

Purpose: The aim of this retrospective clinical trial was to evaluate the eficacy of the 3- rod technique via posterior approach in the surgical treatment of rigid spinal deformities covering scoliosis and kyphoscoliosis. Materials and method: Between years 2003- 2009, 10 patients with rigid spinal deformities (5 scoliosis, 5 kyphoscoliosis) that were treated surgically using 3-rod technique via posterior approach and instrumentation were evaluated retrospectively. Of the 10 patients 5 were female and 5 were male respectively. The mean age was 20.7 years old. During the procedure the apex of the concavity of the main curve was instrumented and distracted as first (1th rod). Then a second rod was inserted to the uppers and the lowest vertebra of the concavity followed by derotation and distraction (2nd rod) A long third rod was then inserted to the convexity of the deformity (3rd rod). In the radiographical assessment, parameters including Cobb angles of the curves, sagittal and coronal balance measurement, apical vertebral translation, thoracic kyphosis with lumbar lordosis, correction gained and lost as well were noted for the preoperative postoperative and final follow-up period respectively. Results: The mean follow up was 45 months. The preoperative major thoracic curve which was 102.6º improved to 56º in the early postoperative period and was measured as 58.1º at the final follow up respectively. The mean initial correction was measured as 45 % and the final correction rate was 43%. The loss of correction at the end of follow up was 2 %. Two patients had sagittal and one had coronal decompenzation as complications. Discussion: On the basis of the final results of the current study it is believed that 3-rod technique via posterior approach may be an effective and safe surgical treatment modality in the management of severe and rigid spinal deformities such as scoliosis and kyphoscoliosis.

Özet

Amaç: Bu çalışmanın amacı, posterior girişimle 3-rod tekniğinin rigid ve ağır deformitelerde güvenli ve yeterli düzelme sağlayarak tedavide ki başarısını geriye dönük olarak değerlendirmektir. Gereç ve Yöntem: 2003-2009 yılları arasında ağır, rijit spinal deformiteli 10 hasta (5 hasta skolyoz, 5 hasta kifoskolyoz) 3-rod tekniği ile posterior enstrümantasyon uygulanarak ameliyat edildi. On hastanın 5'i bayan, 5'i erkek idi. 7 hasta idiopatik, 3 hasta konjenital kökenli deformite idi. Hastaların ameliyat sırasında ki ortalama yaşı 20,7 yaş (Aralık, 14-38) idi. Radyografide üç farklı zamanda (ameliyat öncesi, ameliyat sonrası, ileri takip dönemi) torakal ve lomber eğriliğin Cobb açısı, koronal ve sagittal denge, apikal vertebra translasyonu parametreleri, torakal kifoz, lomber lordoz, deformitenin düzelme oranları, düzelme kayıpları ölçüldü. Posteriordan öncelikle ana eğriliğin tepe noktasının konkav tarafına 1. rod (kısa rod) yerleştirilip distraksiyon uygulandı. 2. rod (uzun rod) eğriliğin konkav tarafındaki üst-son ve alt-son vertebraları arasına yerleştirilip derotasyon ve distraksiyon uygulandı. 3. rod (uzun rod) ise eğriliğin konveks tarafına yerleştirildi. Sonuçlar: Hastaların ortalama takip süresi 45 ay (Aralık, 18-98) idi. Hastaların ameliyat öncesi ana torakal eğrilikteki ortalama Cobb açısı 102.6º (aralık, 67º-132º) iken ameliyat sonrası dönemde 56º (aralık, 26º-96º) olarak ölçüldü. Son takipteki ana torakal eğrilik ortalama Cobb açısı 58.1º (aralık, 27º-98º) olarak belirlendi. Ameliyat sonrası ortalama düzelme % 45.42 iken son takipteki düzelme oranı % 43.37 olarak tespit edildi. İleri takip döneminde ortalama düzelme kaybı % 2.05 olarak tespit edildi. İleri takip döneminde ise 1 hastada koronal dengede bozukluk devam ederken, 2 hastada sagittal dengede bozukluk tespit edildi. Hiçbir hastada klinik bir komplikasyon gelişmedi. Tartışma: Rijit ve ağır skolyoz veya kifoskolyozların düzeltilmesi zordur. Çeşitli osteotomiler ve posterior ve/veya anterior tekniklerle rijit ve ağır spinal deformiteler tedavi edilebilir. Çalışmamız posterior girişimle 3-rod tekniğinin rijid ve ağır deformitelerin tedavisinde etkili ve güvenilir bir teknik olduğunu göstermektedir
