The transcondylar approach (TA) has been used in surgeries to access lesions in areas close to the foramen magnum (FM) and is performed directly through the occipital condyle (OC) or through the atlanto-occipital joint and adjacent portions of the same. The objective of this study is to examine anatomical variations related to the TA by morphometric parameters of the FM, OC and of the hypoglossal canal (HC) in dry skulls and in computed tomography (CT). In 111 skulls, characteristics of the HC, and measures related to the FM, the HC and to the OC were examined. In CT, the measurements obtained bilaterally in 10 patients who underwent examination of the skull base in 1 mm-thick axial helical cuts were the distances from the outer half of the clivus to the... |

The major blood supply to long bones occurs through the nutrient arteries, which enter through the nutrient foramina. This supply is essential during the growing period, during the early phases of ossification, and in procedures such as bone grafts, tumor resections, traumas, congenital pseudoarthrosis, and in transplant techniques in orthopedics. The present study analyzed the location and the number of nutrient foramina in the diaphysis of 885 long bones of the upper and lower limbs of adults: 174 humeri, 157 radii, 146 ulnae, 152 femora, 142 tibiae and 114 fibulae. The location of the nutrient foramina is predominant on the anterior aspect of the upper limb long bones, and on the posterior aspect of the lower limb long bones. The majority of the bones... |
