Özet
Çalışma Dizaynı: Kantitatif anatomik Geçmiş Bilgiler: Literatürde insan ve dana 1. sakral (S1) vertebrasını anatomik olarak karşılaştıran bir çalışma bulunmamaktadır. Amaç: Dana S1 vertebrasında kantitatif anatomik ölçümler yapmak ve bunu mevcut insan kadavra ölçümleri ile karşılaştırmak. Materyal ve Metod: 12 adet taze donmuş dana omurgasından elde edilen (2 yaş) 3 liner ve 2 açısal ölçüm, 12 insan kadavrasına ait ölçümler ile karşılaştırıldı. Dana S1 vertebra pedikül anterior-posterior genişliği (W), pedikül uzunluğu (XP), sefalo-kaudad yüksekliği (H), transvers (T˚) ve sagital (S˚) açılarının ölçümü yapıldı. ‹nsan ve dana kadavra ölçümlerinden elde edilen veriler ‘two-tailed Student t test’ kullanılarak karşılaştırıldı. Sonuçlar: Ortalama pedikül sefalo-caudad yüksekliği (H) insanda 13.6 ± 2.3 mm iken, dana kadavrasında 44.4 ± 4.34 mm olarak ölçüldü (p 0.05). Tartışma: İnsan ve dana S1 vertebraları arasında istatistiksel olarak fark olmakla beraber, insan kadavrası ile karşılaştırılabilirliği açısından, sakral vertebra araştırmalarında dana sakrumu kullanımı cesaret vericidir.
Abstract
Study Design: Quantitative anatomic Background Data: There is no anatomical comparative study between human versus calf first sacral vertebra in English literature. Purpose: To determine quantitative anatomic data of the first sacral vertebra of calf and compare to the human cadaver. Material and Methods: 3 linear and 2 angular parameters were obtained from twelve fresh frozen calves (2 years old) first sacral vertebras and compared twelve female human cadaver measurements. Anterior-posterior width of S1 pedicle (W), pedicle length (XP), cephaladcaudad height of S1 pedicle (H), transverse (T˚) and sagittal (S˚) angle of S1 pedicle were measured. The measurements between calf and human specimens for each parameter were compared with using a two-tailed Student t test. Results: The mean cephalad-caudad height of pedicle (H) were measured 13.6 ± 2.3 mm in the human and 44.4 ± 4.34 mm in the calf (p<0.05). Anterior-posterior width (W) of the S1 pedicle was measured as 22.5 ± 2.6 mm on an average in the human. In the calf, width was measured as 26.02 ± 1.95 mm (p<0.05). The mean length of S1 pedicle (XP) was measured 50.7 ± 3.7 mm in the human, and 76.1 ± 4.3 mm in the calf (p<0.05). The mean S and T angles of S1 pedicle were measured 19˚ ± 2.9˚ and 43˚ ± 2.3˚, respectively in the human. In the calf, the mean S and T angles were 16.37˚ ± 2.5˚ and 44.04˚ ± 5.84˚, respectively. There was a statistical significant difference between human and calf mean sacral T angles (p< 0.05). However, there was no statistical differences between mean S angles (p>0.05). Conclusion: Although there were some statistical differences between the human and calf S1 vertebras, the good comparability with the human spine encourage the use of the two years old calf S1 spine
