Identification of the neural pathways involved in retraining the spinal central pattern generators (CPGs) by afferent input in the absence of descending supraspinal control is feasible in isolated rodent spinal cords where the locomotor CPGs are potently activated by sacrocaudal afferent (SCA) input. Here we study the involvement of sacral neurons projecting rostrally through the ventral funicu...

The extradural space is currently investigated through fluoroscopy and ultrasound for surgical approach, whereas magnetic resonance imaging has been used to provide detailed information. The aim of the present paper is to describe the radiologic anatomy of the sacral canal through a review of its appearance in the different radiologic techniques. CT is able to visualise also the sacrum and the ...

The authors report on an important differential diagnosis of back pain in a pregnant woman caused by an atraumatic insufficiency sacral fracture. This diagnosis is a rare entity in pregnant patients and may often be overlooked due to nescience by the treating physicians. The authors discuss the diagnostic and treatment options in undisplaced sacral fractures and their successful natural treatme...

Sacral insufficiency fractures frequently cause significant pain and limit activities of daily living in patients with osteoporosis. Percutaneous vertebroplasty is a common procedure to alleviate the pain associated with thoracic and lumbar vertebral compression fractures. The sacral percutaneous vertebroplasty procedure (sacroplasty) has recently been introduced as an alternative to medical ma...

Pre-sacral epidermoid cysts are rare development cysts resulting from dysembryogenesis mostly diagnosed in middle aged women. We report a case of pre-sacral epidermoid cyst presenting with recurrent perianal sinus in young girl. Generally pre-sacral epidermoid cysts are seen in adult age group but it is rare presentation in young age group. We report a rare case of presacral epidermoid cyst occ...

Sacral colpopexy is the gold standard for vaginal vault suspension throughout the literature. The operation is considered to be invasive yet very effective. The laparoscopic approach to the sacral colpopexy is not only effective but can have minimal morbidity in the correct surgeon's hands. The authors have performed more than 500 sacral colpopexy via laparoscopy with minimal morbidity and thus...

Fifteen cases of primary sacral pathology were analyzed. High-resolution computed tomography was found to be the most accurate means of studying these cases. Certain anatomic changes involving the central canal and sacral foramina were found to be helpful in determining the type of pathology. Although conventional plain films, radionuclide bone scans, and myelography were useful in certain case...

One of the most important steps of this technique is the correct topographic anatomic identification of the posterior sacral foramina on the body surface of the sacrum [6,7]. Although the sacrum’s anatomy is recognized to be highly variable. In the literature there are several studies regarding the variable morphology of the sacrum that also shows high incidence of sacral malformations, ranging...

BACKGROUND Sacral slanting is a frequent unique phenomenon in patients with adolescent idiopathic scoliosis (AIS) and may be important for selecting the distal fusion level. However, the reason of the phenomenon remains unknown. The purpose of this study was to determine the association between sacral slanting and adjacent structures in patients with AIS. METHODS A total of 303 AIS patients w...
