The morphometry of thoracic pedicles and pedicle-rib units and their relations to aorta: An MRI study

Öz:
Amaç: Pedikül içerisinden vida uygulamanın zor olduğu torakal omurgada daha güvenli ve sağlam bir alanı ortaya koymak. Materyal - Metod: Torakal omurgasına ait hiçbir yakınması olmayan 42 erişkin (21 erkek, 21 kadın) çalışma gubunu oluşturdu. Yaş ortalaması 36.7(16-56) idi. T1’den T12’ye kadar manyetik rezonans görüntüleme (MRG) ile gerçek aksiyel kesitler elde edildi. MRG kesitlerinde transvers pedikül çapı, transvers pedikül-kot alanı çapı, pedikül vida yolu uzunluğu, pedikül-kot alanı vida yolu uzunluğu, pedikül vida yolunun aorta ile ilişkisi, pedikül-kot alanı vida yolu ile aorta ilişkisi bilgisayar programı aracılığı ile ölçüldü. Sonuçlar: Pedikül ile pedikül-kot alanı çapı arasında ve pedikül vida yolu uzunluğu ile pedikül-kot alanı vida yolu uzunluğu arasında istatistiksel olarak anlamlı fark tespit edildi. Konvansiyonel vida yolu kullanıldığında sol tarafta yüksek olan aorta yaralanma riski, pedikül-kot alanı vida yolu kullanıldığında sağ tarafta yüksektir. Çıkarım: Nörolojik yaralanma riski açısından pedikül vida yolu ve pedikül-kot alanı vida yolu karşılaştırıldığında pedikül-kot alanı epidural alandan uzak bir vida yolu sağlamaktadır. Buna karşın aortu yaralama riski pedikül-kot alanı kullanıldığında sağ tarafta, pedikül vida yolu kullanıldığında sol tarafta yüksektir. Hibrid uygulama (sol tarafta pedikül-kot vida yolu, sağ tarafta konvansiyonel pedikül yolunun kullanımı) pedikül çapının uygun olduğu olgularda hem nörolojik, hem de aort yaralanma riskini azaltabilir.

Aim: The objective of the study is to determine the safe and reliable area in thoracic spine that application of intrapedicular screw is difficult. Materials and Methods: A study group is constituted 42 adults (21 men, 21 women) who have no medical history about thoracic spine. The mean age was 36.7(16-56) years old. True axial cross sections passing through both pedicles between T1 to T12 were taken with MRI. On these MRI cross sections, width of transverse intraosseous pedicle, width of transverse intraosseous (Pedicle Rib Unit) PRU, length of pedicle screw path, length of PRU screw path, relation of pedicle screw path with aorta and relation of PRU screw path with aorta were measured with the help of a computer programme. Results: A statistically significant difference was found on each level between the transverse intraosseous width of pedicle and those of PRU, and length of pedicle screw path and those of PRU. While injury risk for aorta is high on the left side when the conventional pedicle screw path is used, it is high on the right side when PRU screw path is used. Conclusions: When we compared PRU screw path with those of conventional pedicle screw path in point of neurological injury risk; PRU screw path provide us to keep away from epidural space. On the contrary, the injury risk of aorta is high at the right side PRU screw path used and is high at the left side when the conventional pedicle screw path used. Hybrid application (the using of PRU screw path at the left side and the using of conventional screw path at the right side) may minimize both neurological and aortic injury risk when the pedicle width is adequate.
