BACKGROUND Several authors have defined a variety of so-called safe zones for deltoid-splitting incisions. The first aim of the present study was to investigate the distance of the axillary nerve from the acromion and its relation to arm length. The second aim was to identify a safe area for the axillary nerve during surgical dissection of the deltoid(More)
The anatomy of the nasolacrimal duct (NLD) in relation with the lateral nasal wall was studied in 15 half-heads of human adult cadavers by serial photographs of the dissection of the lateral nasal wall. The aim of the study was to determine the intranasal anatomical relationships of the NLD with the lateral nasal wall for surgical reference during(More)
AIM To examine the anatomy, length and angulation of the anterior and posterior ethmoidal canals (AECs and PECs) using computed tomography (CT), and to determine the anatomical landmarks in which the canals are expected to be seen in transverse and coronal planes. MATERIALS AND METHODS CT images of 150 patients were analysed. One, 2, and 3 mm thick(More)
BACKGROUND Despite documentations of ligamentous structures of the elbow, the anatomy and clinical and functional importance of the annular ligament has not been comprehensively defined in the orthopaedic literature. HYPOTHESIS The annular ligament is an important component of both the proximal radioulnar and humeroradial joints, as well as an important(More)
Anatomical knowledge regarding the long thoracic nerve (LTN) is important during surgical procedures considering that dysfunction of this nerve results in clinical problems. The purpose of this study was to explore the anatomy of the LTN, its origin, configuration, branching pattern, and relationship to the middle scalene muscle (MSM). The course of the LTN(More)
BACKGROUND One of the most important aspects for patients undergoing rectal cancer surgery is quality of life, which is closely related to postoperative sexual, urinary, and bowel functions. To preserve these functions, surgeons need to pay special attention to the fascial planes and autonomic nerve plexuses. OBJECTIVE The aim of this study is to describe(More)
The objective of this study was to analyze relationship of the intervertebral disc to the nerve root in the intervertebral foramen. Fourteen formalin-fixed cadavers were studied and measurements were performed. At the medial line of the neural foramen, the disc-root distance gradually increased from L1-L2 to L5-S1. The shortest distance between the disc to(More)
OBJECT Although infrequent, injury to adjacent neurovascular structures during posterior approaches to lumbar intervertebral discs can occur. A detailed anatomical knowledge of relationships may decrease surgical complications. METHODS Ten formalin-fixed male cadavers were used for this study. Posterior exposure of the lumbar thecal sac, nerve roots,(More)
