Abstract

Objectives: This study aims to examine the motion andstability of the adjacent segment following rigid fixation of thelumbar spine.Materials and methods: The study included 17 fresh-frozenlamb lumbar spines (including the sacrum to T12). Biomechanicaltesting was performed using an axial compression testingmachine. Axial compression was applied to all the specimensusing a loading speed of 5 mm min-1. A specifically designedfixture was used to generate torque ≤8400 Nmm. The fixture was used with each specimen to achieve flexion and extension, axial neutral compression, and right and left bending. All specimens were tested intact, and again after implantation using posterior pedicle screws and rod fixation. During testing intervertebral displacement at the adjacent level (L5-S1) was recorded continuously via extensometry.Results: Axial compression and superior-inferior displacementwere lower in the adjacent segment (L5-S1) than anterior-posteriordisplacement following rigid fixation. Statistical analysis showedthat there was a numerical difference and a significant changebetween the intact spine and the adjacent segment in the axialcompression and extension positions (p

Özet

Amaç: Bu çalışmada lomber omurganın rijit tespitinden sonra komşu segmentin hareket genişliği ve stabilitesi araştırıldı. Gereç ve yöntemler: Bu çalışmada 17 taze donmuşkuzu lomber omurgası (sakrum T12’yi içeren) kullanıldı. Biyomekanik test aksiyel kompresyon test cihazı ile yapıldı. Aksiyel kompresyon tüm numunelere 5 mm/dk. yükleme hızı ile uygulandı. Özel dizayn edilmiş fikstür ile 8400 Nmm tork oluşturuldu. Fikstür aksiyel yönde fleksiyon, ekstansiyon, sağ ve sola eğilme pozisyonlarında yüklenme uygulanacak şekilde numuneler ayarlandı. Tüm numuneler sağlam omurga, pedikül vida ve rod fiksasyonu sonrasında teste tabi tutuldu. Test esnasında komşu seviye L5-S1 arasındaki ayrılma değerleri süreğen bir şekilde ekstansometre ile kaydedildi. Bulgular: Komşu segmentte (L5-S1), aksiyel yüklenme veüst-alt ayrılma değerleri, ön-arka ayrılma değerlerindendüşük bulundu. İstatistiksel analizde sağlam omurga ile komşu segment arasında aksiyel kompresyon ve ekstansiyon pozisyonunda sayısal anlamlı değişiklikler tespitedildi (p
