A morphometric study of the linear and angular parameters of the spinal vertebra was conducted by computerized tomographic scans and comparison with previous studies in literature. ⋯ In our morphometric study of the spinal vertebrae, we found differences compared to a number of previous morphometric studies performed mainly on a white population. Also, we documented the individual morphometric differences of the same parameters in the same subgroups. These results emphasize the importance of preoperative computed tomography and conventional radiography of each patient in planning a surgical procedure and selecting the appropriate size of the instruments, thus avoiding possible postoperative complication related to implants.

The objective of the study was to provide statistical evaluation of position of bone landmarks of proximal humerus in relation to transepicondylar line and find out which one is the most suitable for setup of the head retroversion in case of humeral head destruction. ⋯ We statistically proved that the lateral margin of lesser tuberosity is more reliable than the bicipital groove; medial margin of the greater and transepicondylar line for reconstruction of humeral head retroversion. We suggest that the lesser tuberosity should be used to determine the retroversion, especially in cases when the margin of humeral head was destructed.

The variations in the emergence and distribution of the ilioinguinal nerve are the cause of the failures of the ilioinguinal block and the difficulties at interpreting the ilioinguinal nerve syndrome. In order to identify its variations and set reliable anatomical landmarks for performing the ilioinguinal block, we dissected 100 inguinal regions of 51 adult corpses. The nerve was absent in seven cases and double in one case. ⋯ Sixteen modes of division and eight types of predominantly anterior scrotal topographic distribution could be noted. These results show the high variability of the emergence and the sensory distribution of the ilioinguinal nerve. They enable us to propose techniques for ilioinguinal block performance using more accurate anatomical landmarks formed by the inguinal ligament and the ventral cranial iliac spine and a better diagnostic approach of ilioinguinal neuropathies.

Dissection workshop has never been assessed in the initial training of resident medical students in anesthesia. This work aimed at assessing the impact of this educational tool on the rates of success of the main blocks the resident in anesthesia achieved during their training. ⋯ Although the educational quality of the training was acknowledged as responding to the expectancies of the anesthesia residents, the dissection workshop do not meet with the expected requirements of rates improval of the different blocks part from the humeral canal one's, within this medical sample in initial training.

The vasculature and anastomosis around the scapula is extremely intricate making surgical treatment complicated. We aimed to determine the "at risk area" for the circumflex scapular artery and its anastomosis with the suprascapular artery during posterior approach to the scapula. ⋯ We were able to identify the relationship of the circumflex scapular artery to the anatomic landmarks of the scapula and to define the "at risk area" for the ascending branch of the circumflex scapular artery and its anastomosis with the suprascapular artery. We believe our anatomical study may aid in the avoidance of vascular complications during internal fixation of scapular fractures.
