INTRODUCTION: The supratrochlear aperture (STA) is the opening observed in the septum that separates the olecranon from the coronoid fossae. Numerous studies have shown that there is considerable variation in the occurrence of this feature within and among populations. MATERIALS AND METHODS: Cadavers (n = 43) were assessed for the presence of the STA by means of X-ray. Ten samples of STA-bearing bones and an equal number of controls without STA were obtained from cadavers using a hole saw...

PURPOSE: Controversy exists as to whether a high or low tie ligation of the inferior mesenteric artery (IMA) is the preferred technique in surgeries of the left colon and rectum. This study aims to contribute to the discussion as to which is the more beneficial technique by investigating the neurovasculature at each site. METHODS: Ten embalmed cadaveric donors underwent division of the inferior mesenteric artery at the level of the low tie. The artery was subsequently ligated at the root to render a section of tissue for histological analysis of the proximal (high tie), mid and distal (low tie) segments...

PURPOSE: The thoracolumbar fascia (TLF) and the erector spinae aponeurosis (ESA) play significant roles in the biomechanics of the spine and could be a source of low back pain. Attachment, collagen fiber direction, size and biomechanical properties of the TLF have been well documented. However, questions remain about the attachment of the TLF and ESA in relation to adjoining tissues in the lumbosacral region. Moreover, quantitative data in relation to the ESA have rarely been examined...

PURPOSE: The position of the fovea of the femoral head is usually considered to be inferior or inferoposterior, despite the fact that few detailed anatomical studies have been performed. This study was performed to assess the position of the fovea in computed tomography and its correlation with standard radiographic measures of the proximal femur. METHODS: Computed tomography scans of the hip of 107 patients (54 women and 53 men) were evaluated. The semi-coronal and transverse views were used to assess the femoral neck-shaft angle and the neck version, as well as the size and position of the fovea in relation with the femoral neck axis and the size of the head...

PURPOSE: The coupled behavior of talocrural joint motion is primarily determined by the morphological features of the talar trochlea and tibiofibular mortise. Features of the radius of curvature of the talocrural joint, however, remain unclear. The objectives of this study were to evaluate the radius of curvature at the mid, medial, and lateral regions of both the talar trochlea and the tibial plafond, and to estimate subject-specific kinematics of the talocrural joint. METHODS: Computed tomography images of 44 subjects with healthy talocrural joints were assessed by creating three-dimensional bone models...

PURPOSE: Vertebral segmentation and fusion failures are quite common and often occur as incidental findings. These anatomical variants may be associated with deformity and lead to pain and other neurological signs. They are less frequent in the cervical spine. We report three cases of rare posterior arch segmentation failure at the cervical spine and cervicothoracic junction, with an interesting pattern of laminar arrangement. METHODS: The clinical and radiological findings of three patients with unusual anatomical variants of the posterior elements of the subaxial cervical spine and cervicothoracic junction are reported...
