Sacrum is wedge shaped bone between two iliac bones forming posterior wall of pelvis. Normally, sacrum is generated by fusion of five sacral vertebrae constituting four pairs of sacral foramina [1]. At the cranial end of sacrum, there is fifth lumbar vertebra which when fused with the first sacral vertebra is known as sacralization of lumbar vertebra. Similarly at the caudal end, first coccygea...

The sacrum represents a key anatomical element for understanding Dinosauria, beginning with the first use of the taxon name in 1842. A five-vertebra sacrum was originally considered diagnostic of dinosaurs, and variation in the number of sacral vertebrae has been used to diagnose smaller groups of dinosaurs. Despite its centrality to early definitions of Dinosauria, utility for diagnosing small...

BACKGROUND Persons with low back pain fail to show the same transition as healthy individuals from in-phase to anti-phase rotation of the thorax and pelvis as walking speed increases. The purpose of this study was to determine if the relative phase of the thorax and pelvis during walking was a reliable (within day test-retest) and valid measure for persons with thoracic pain. METHODS The time...

Aims: The purpose of this study is to assess the architecture and clinical importance sacrum, which features dorsal pelvic nerves.
 Methods: 32 os sacrum adult Anatolians undetermined gender were measured for investigation. Sacrum maximum length, width, I vertebral body antero-posterior transverse sacral index, Auricular surface short arm, auricular long arm oblique measurements linea leng...

fractures through the sacroiliac joint are very challenging to treat, technically difficult to reduce through closed methods on account of the multiaxial displacement of fractures fragments, frequently occur in very unwell patients, and have poor outcomes if malreduction is present. we describe a technique utilising the lateral window and a short buttress plate to reduce and stabilize the fragm...

fractures of the os sacrum can be the cause of severe pain and immobility. a common cause of insufficiency fractures is osteoporosis. in elderly and multimorbid patients, the complications of conservative therapy can sometimes be severe. in the meantime, good outcomes with regard to pain reduction and improved mobility are achieved with ct-assisted balloon sacroplasty. we report on the successf...
