The posterior sacral foramina: an anatomical study.
The vascular and nervous structures and their relations with the spinal nerve roots were examined in the 2nd, 3rd and 4th posterior sacral foramina in relation to percutaneous needle insertion for neuromodulation. A foraminal branch provided by the lateral sacral artery to each foramen entered the inferior lateral quadrant of each foramen, adjacent to the nerve root medially. Facing the posteri...

متن کاملAnatomical observations of the foramina transversaria.
Four hundred and eighty foramina transversaria in dry cervical vertebrae of 36 spines and in a number of dissections were studied and classified according to size, shape, and direction of their main diameter. A coefficient of roundness was then elaborated. The variations of foramina appear to follow a pattern at various vertebral levels. The possible factors (in addition to the embryological on...
متن کاملAn Anatomical Study of the Nutrient Foramina of the Human Humeral Diaphysis
BACKGROUND Understanding the nutrient foramina is critical to clinical practice. An insult to the nutrient foramina can be caused by trauma and/or surgical dissection and lead to devascularization and bad outcomes. Few studies have looked at the humerus, and no studies have described relative information of humeral nutrient foramen related to anatomical structures that might be located by palpa...
متن کاملFemoral Insertion of the Posterior Cruciate Ligament: an Anatomical Study.
OBJECTIVE To identify objective parameters to guide correct location of the posterior cruciate ligament (PCL) in the femur. METHODS The PCLs of 20 human cadavers were resected. The following portions were measured: distance from the most distal portion of the PCL, close to the roof, to the most anterior edge of the cartilage (AB); distance from the most proximal portion of the PCL, close to t...
