AIMS To test different technical setups for stimulation and recording of the sacral reflex, provide confidence intervals and discuss the utility of the sensory threshold and the sacral reflex threshold in women with "non-neurogenic" sacral dysfunction. METHODS All women without neurologic disorder, with normal neurologic examination, and bilaterally normal quantitative electromyography of the...

Os cordomas sacrais (CS) são tumores ósseos malignos primários da coluna vertebral de ocorrência rara, com incidência entre 0,000005-0,000027%. O objetivo deste estudo é relatar um caso CS metastático. Homem 41 anos idade, sem comorbidades, chega ao serviço referência apresentando lesão sacral. Ressonância magnética mostrou tratar-se tumor 9,3 cm sugestivo mieloma ou cordoma. Realizou-se biópsi...

BACKGROUND Upper sacral segment dysplasia increases the risk of cortical perforation during iliosacral screw insertion. Dysmorphic sacra have narrow and angled upper osseous corridors. However, there is no validated definition of this anatomic variation. We hypothesized that pelves could be quantitatively grouped by anatomic measurements. METHODS One hundred and four computed tomography (CT) ...

Abstract 49-year-old relatively healthy man presented to the ER with abdominal and associated low back pain. Past history was significant for excision of spinal benign tumor 30-year pack smoking. Review systems recurrent leg swelling muscle aches. Neurological exam non focal. CT scan abdomen pelvis revealed a lytic sacral lesion soft tissue component. The rest skeletal survey system evaluation ...

The laminae of fifth and sometimes fourth sacral vertebrae fail to fuse posteriorly in the sagittal plane leading to formation of a deficiency in the posterior wall of the sacral canal commonly known as sacral hiatus. During osteology demonstration class of MBBS students of the Department of Anatomy, U.C.M.S and G.T.B Hospital, Delhi, we noticed a sacrum in which sacral hiatus was extending to ...
