Özet
Sunulan çalışma; elit erkek haltercilerden ve sedanter (kontrol) grubundan multidedektör bilgisayarlı tomografi (MDBT) ile alınan columna vertebralis kesitlerinden, fotogrametrik yöntemlerle üç boyutlu veri ve modeller elde edilerek, elit haltercilerin ve sedanter grubunun omurga yapısının biyometrik özelliklerini ortaya koymak amacıyla gerçekleştirilmiştir. Çalışmada 8 adet elit erkek haltercinin ve 8 adet sedanterin columna vertebralis'i yüksek çözünürlüklü diagnostik MDBT cihazıyla tarandı. Elde edilen 2B'li axial görüntüler DICOM formatında CD'lere aktarıldıktan sonra, içerisinde üç boyutlu modelleme programı olan 3D-Doctor 4.0 yüklü kişisel bilgisayara aktarıldı. 3D-Doctor sayesinde, ilk aşamada 2D'li görüntüler üzerinde yarı-otomatik segmentesyon prosedürü gerçekleştirildi. İkinci aşamada bu prosedürde çıkması muhtemel olan düzensiz noktaların modifiye edilmesi için aynı görüntüler üzerinde interaktif düzeltme rutiniyle manuel segmentasyon yapıldı. Manuel olarak segmente edilmiş görüntüler bloklaştırılıp üst üste bindirildikten sonra ilgili programlar sayesinde üç boyutlu hale getirildi. Tüm ölçümler adı geçen program yardımıyla otomatik olarak hesaplandı ve istatistiki analizler SPSS 15.0 paket programında (SPSS For Windows 2006) t- testi ile belirlendi. Columna vertebralis'in istatistik sonuçları incelendiğinde, elit haltercilerde ve sedanterlerde, sadece Pars lumbalis'in uzunluklarında L3-L5 omurları arasında istatistiksel açıdan önemli farklar (P<0.05) kaydedildi. Canalis vertebralis'in istatistik sonuçları incelendiğinde, elit haltercilerde ve sedanterlerde, Pars cervicalis' in hacim; C7, yüzey alanı; C5, C6 ve C7 ve uzunluk; C7 segmentlerinde istatistiksel açıdan önemli farklılıklar (P<0.05) kaydedildi. Pars thoracalis'in hacim; T2, T7 ve T8 ve uzunluk; T4, T7 ve T8 segmentlerinde istatistiksel açıdan önemli farklılıklar (P<0.05) kaydedildi. Pars lumbalis'in hacim; L5, yüzey alanı; L2-L3-L5 segmentlerinde istatistiksel açıdan önemli farklılıklar (P<0.05) kaydedildi. Bütün volumetrik ölçümler değerlendirildiğinde; columna vertebralis'in ve canalis vertebralis'in sadece L5 segmentindeki deformasyonun daha dikkate değer olduğu tespit edildi. Sonuç olarak, bu tekniklerin ve üç boyutlu rekonstrüksiyon prosedürlerinin spor hekimliğinde kullanım alanına girmesinin gerekliliği düşüncesinden hareketle, MDBT tekniğiyle halter sporcuları üzerinde gerçekleştirilecek alt yapı çalışmalarının bu tür araştırmalarla destekleneceği düşünülmektedir.
The aim of his study is to present biometrical features of spine structures of elite powerlifters and sedentary men by acquiring three-dimensional data and models using photogrammetric survey from vertebra column sections that derived from elite male powerlifters and sedentary men by using multidetector computed tomography (MDCT). In this study, vertebra columns of eight elit male powerlifters and eight sedentary men were scanned by means of high resolution diagnostic device MDCT. After transferring the obtained 2D axial images to CDs in DICOM format, these images were transmitted to personal computer that has a three dimensional modelling programme, 3D-Doctor 4.0 in the first stage, semi-automatic segmentation procedure was performed on 2D images thanks to 3D-Doctor. During the second stage, manuel segmentation with interactive adjustement was carried out on the same images in order to modify the uneven places that were possible to emerge. After the images mounted manually were configured and overlapped, they were rendered in three dimensional by means of the related programme. All measurements were figured up automatically by means of the aforenamed programme and the statistical analyses were designated by using the t-test in SPSS 15.0 packeged software. When the statistical inferences of vertebra columns are examined, in elite powerlifters and sedentary men, statistically remarkable differences (P<0.05) were only detected in the lenghts of pars lumbalis between L3 and L5 vertabras. When the statistical inferences of Canalis Vertabralis are examined, in elite powerlifters and sedentary men, statistically remarkable differences (P<0.05) were detected in some segments of pars cervicalis: in terms of volume; C7, surface area; C5, C6 and C7 and the lenght; C7. Also some other statistically important differences (P<0.05) were detected in pars thorocalis: in terms of volume; T2, T7 and T8 and in terms of lenght; T4, T7 and T8. Once again, in the volume; L5 and in surface area; L2,L3 and L5 segments of pars lumbalis, remarkable differences (P<0.05) were detected. When the all volumetric measurements were assessed, it was determined that the deformation is more significant in only L5 segments of vertebra columns and vertabra canal. As a consequence, considering the fact that these techniques and three dimensional reconstruction procedures should be in sports medicine, it is thought that infrastructure works which will be performed by using MDCT and related to powerlifters will be supported by such researches.
