| English abstract | For the evaluation of the Lumbar pedicle morphometry and its relation to the neural structures, 14 male adult cadavers were dissected, and the size of the lumbar pedicle was assessed by measuring its sagittal and transversal diameter. It was found that the size of the pedicle increases from L2 to L5, both in the sagittal and transversal diameter, the first bigger. The relation of the lumbar pedicle to the neural structures was evaluated by measuring the distance between dura-mater and the pedicle medial area, the distance between the most distal area of the pedicle and the nerve root that appears under it, and , to obtain in an indirect way, the distance between the pedicle apex and the nerve root that appears over it. The acquired results showed that the distance between the most distal area of the pedicle and the nerve root that appears under it, and the distance between the pedicle medial area and dura-mater, do not increase from L2 to L5, and they are in average 1,98 and 3,02 respectively. The distance between the pedicle apex and the nerve root that appears over it, increases from L2 to L5, varying from 13,64 in L2 to 21,62 in L5. The location of the spinal ganglion in relation to the pedicle has also been found, and 87% of the spinal ganglions are located in the foraminal zone |
| Portuguese abstract | Para avaliação da morfometria do pedículo vertebral lombar e sua relação com as estruturas neurais, foram dissecados 14 cadáveres do sexo masculino, adultos, onde foram avaliados o tamanho do pedículo vertebral lombar, através da mensuração do seu diâmetro longitudinal e transversal. Os dados obtidos mostraram aumento do pedículo de L2 a L5, tanto no diâmetro longitudinal quanto transversal, sendo o primeiro maior. A relação do pedículo lombar com as estruturas neurais, foram avaliadas através da mensuração da distância da dura-máter à borda medial do pedículo, entre a região mais distal do pedículo à raiz nervosa que emerge abaixo deste e, de maneira indireta, a distância entre o ápice do pedículo à raiz nervosa que emerge acima deste. Os resultados obtidos mostraram que a distância entre a parte mais distal do pedículo e a raiz nervosa que emerge abaixo deste, e a distância entre a borda medial do pedículo à dura-máter, não aumentam de L2 a L5. Quanto à distância entre o ápice do pedículo à raiz nervosa que emerge acima, aumenta de L2 a L5. Localizamos também o gânglio espinhal em relação ao pedículo, sendo que 87% dos gânglios espinhais localizam-se na zona foraminal |
