Üç Boyutlu Yazıcı Destekli Üst Torakal Kırıkların (T1-6) Enstrumantasyonu

Hastaya özgü 3B modeller, cerraha preoperatif olarak cerrahi planlama ve uygulama imkanı sunarak peroperatif komplikasyonları azaltmaktadır. Bu çalışmanın amacı, Üst torakal pedikül vidası tekniği kullanılarak posterior spinal füzyon yapılacak olan hastaların 3B yazıcı ile oluşturulan preoperatif modelleri üzerinde cerrahi planlama ve uygulamasının klinik sonuçlara etkisini araştırmaktır. Kliniklerimize atlantoaksiyel dislokasyon nedeniyle başvuran 6 hasta bu çalışmaya alınmıştır. Üç boyutlu baskı materyalinin üretimi için özel tasarımlı katmanlı üretim teknolojisi olan üç boyutlu yazıcı kullanıldı. Preoperatif modeller üzerinde cerrahi planlama yapıldı ve uygulandı. Hastaların yaş ortalaması 47.16±13.40 (25-64) yaş idi. 6 hastanın 4’ü erkek(%66.7), 2’si kadındı (%33.3).Bu hastaların hepsi travma nedeniyle kliniğimize başvurdu Hastaların operasyon süresi ortalama 253.33±74.47 dk (170-360). Hastaların ortalama yatış süresi 13.83±9.06 gündü. Preoperatif üç boyutlu modellemenin yardımı ile yapılan spinal enstrümantasyon, üst torakal kırık tedavisinde etkili bir yöntemdir. Bu modellerin kullanımı, ameliyat öncesi simülasyon yapma becerisini artırarak cerrahlara avantajlar sunar. 3B’lu modelleme tekniği ameliyat sırasında, vida malpozisyonu azaltır, ameliyat süresini kısaltarak intraoperatif güvenliği artırır.

3D Printing Assisted Upper Thoracic Vertebra (T1–6) Fractures Instrumentation

Three dimensional (3D) printed models specific to the patients, decrease peroperative complications by providing preoperative surgical planning and application opportunities to the surgeon. The aim of this study is to determine the clinical results of preoperative surgical planning and application on 3D printed models, in patients with upper thoracic vertebral fracture treated via pedicle screw and posterior spinal fusion. 6 patients in total with upper thoracal fracture from our clinics were included to this study. 3D printer with custom design printing capability and lamellar printing technology was used for the production of 3D models. Preoperative surgical planning and application were perfomed on the models. The mean age of the patients was 47.16±13.40 (25-64). 4 (66.7%) of 6 patients were males and 2 (33.3%) were females. All presented after a history of trauma. The mean operation duration was 253.33±74.47 minutes (170-360). The mean duration of hospitalization was 13.83±9.06 days. Spinal instrumentation with the assistance from preoperative 3D models is an effecitve and reliable treatment for upper thoracic vertebral fractures. Use of the 3D models increases the ability of preoperative simulation in favor of the surgeon. This technique decreases the risk of screw malposition and shortens the operative duration thus enhances intraoperative reliability.
