Extended anterolateral transiliac approach to the sacral plexus.

The approach to the sciatic plexus and lateral part of the sacrum is difficult. A subperitoneal anterolateral approach can be extended by sectioning the iliac bone above the acetabulum and lowering it toward the external part of the iliac wing and buttock. This transiliac anterolateral approach exposes the lumbosacral trunk, first sacral foramina and sciatic plexus to the origin of the sciatic trunk.

TERTp Mutation Detection in Plasma by Droplet-Digital Polymerase Chain Reaction in Spinal Myxopapillary Ependymoma with Lung Metastases.

Background: Spinal myxopapillary ependymoma (SP-MPE) is a subgroup of ependymomas in which after initial gross tumor resection, recurrences occur in more than half of the patients. Anaplastic transformation may also occur and contributes to intraneural and extraneural metastatic dissemination. Extraneural metastases from SP-MPE are rare and worsen the prognosis.

The article critique as a problem-based teaching method for medical students early in their training: a French example using anatomy.

In France, "article critique" became a particular teaching method in the second part of the medical curriculum. It approaches a reading exercise of scientific medical papers similar to that of journal club. It could be compared to reviewing a paper as performed by reviewers of a scientific journal.

Vascular anatomical basis of clavicular non-union.

The middle third of the clavicle is commonly involved in any injury and account for 5-10% of all fractures in adults. Although non-unions are rare, their treatment has not been well defined yet. This report describes the arterial supply of the clavicle to clarify the pathological mechanism and the surgical procedure of non-unions.

Morphometric study of the shoulder and subclavicular innervation by the intermediate and lateral branches of supraclavicular nerves.

Background: The supraclavicular (intermediate) and supra-acromial (lateral) branches of supraclavicular nerves contribute to the innervation of the thorax, shoulder, and neck. Despite their clinical and surgical interest, they are not often considered for descriptive anatomy. The goal of this work was to clarify the morphometric knowledge of these two branches and to discuss the clinical relevance of the anatomical features.
