BACKGROUND The groin flap, based on the superficial circumflex iliac artery, was the first successful free flap. However, its popularity was lost essentially due to variable arterial anatomy. Clinical applications of perforator flap based on superficial circumflex iliac artery suggest that a dominant perforator based on his deep branch is enough to supply a(More)
BACKGROUND Detailed anatomy of the anterior commissure is unknown in the literature. OBJECTIVE To describe the anterior commissure with the use of a fiber dissection technique by focusing on the morphology (length and breadth of the 2 portions), the course, and the relations with neighboring fasciculi, particularly in the temporal stem. METHODS We(More)
Recent theories about migraine pathogenesis have emphatized the role of the trigeminal system in the pathogenesis of migraine attacks. The local vasodilatation of intracranial extracerebral blood vessels and the consequent stimulation of surrounding trigeminal sensory nerve pain pathways are proposed to be the key mechanisms underlying the generation of(More)
Tumors of the frontal horn of the lateral ventricle (LV) are only supplied by the posteromedial choroidal artery. Tumors of the body of the LV are supplied by the same artery. Tumors of the atrium of the LV with anterior extension are supplied by both posteromedial choroidal and posterolateral arteries. Tumors of the atrium with inferior extension are(More)
INTRODUCTION The aim of this study was to assess the presence of an occipital sinus in both children and adults, and to detail its main associated anatomical characteristics. METHODS One hundred of patients' MRI (3D T1 EG) between 0 and 86 years old were studied, in sagittal and axial sections, with the software DxMM. Occipital sinus length, perimeter,(More)
INTRODUCTION The anterior communicating artery (ACoA) gives perforating branches to the optic chiasma, the hypothalamus and the corpus callosum. Perforating branches are variable (number, direction). Nevertheless, their knowledge is crucial during surgery of this area to spare injuries leading to ischemic post-operative complications. OBJECTIVE The(More)
BACKGROUND Ansa pectoralis neurotomy is a surgical approach in the treatment of the pectoralis major muscle spasticity causing an attitude in adduction and internal rotation of the shoulder. OBJECTIVE To establish the anatomical landmarks allowing an easier localisation of the ansa pectoralis during neurotomy. MATERIAL AND METHODS Fifteen adult human(More)
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(More)
Restoring the joint line level is one of the surgical challenges during revision of total knee arthroplasty. The position of the tibial surface is commonly estimated by its distance to the apex of fibular head, but no study evaluating this distance accurately has been published yet. The purpose of this work was to study the distance between the knee joint(More)
BACKGROUND The risk of damage to cutaneous sensory nerves located near portals has been evaluated for both conventional arthroscopy and extra-articular posterior ankle endoscopy. The objective of the anatomic study reported here was to assess the risk of injury to the sural nerve or lateral calcaneal nerve while using the distal lateral portal for the(More)
