Unstable pelvic ring fractures raise treatment challenges in severely injured patients. Ilio-sacral screw fixation is an elegant option for stabilising the posterior lesion, which is a common source of residual pain. This technique provides secure fixation. The first description can be found in a 1913 treatise by Lambotte [1]. In 1978, Letournel reported the treatment of sacro-iliac joint dislo...

It is unclear if a decrease in cancellous bone density or cortical bone thickness is related to sacral insufficiency fractures. We hypothesized that reduction in overall bone density leads to local reductions in bone density and cortical thickness in cadaveric sacra that match clinically observed fracture patterns in patients with sacral insufficiency fractures. We used quantitative computed to...

Perineurial cysts (Tarlov cysts) are lesions of the nerve root that are often observed in the sacral area. There is debate about whether symptomatic perineurial cysts should be treated surgically. We presented three patients with symptomatic perineurial cyst who were treated surgically, and introduced sacral recapping laminectomy. Patients complained of low back pain and hypesthesia on lower ex...

Lumbosacral osteomyelitis and discitis are usually a result of hematogenous spread; rarely it can result from direct inoculation during a surgical procedure. Bacteria may also track along implanted devices to a different location. This is a rare complication seen from pelvic organ prolapse surgery with sacral colpopexy. A 67-year-old female developed increasing lower back pain four months follo...

A 76-year-old man presented with a Denis Zone III sacral fracture after a traffic accident. He also developed urinary retention and perineal numbness. The patient was diagnosed with neurogenic bladder dysfunction caused by the sacral fracture. A computed tomogram (CT) revealed that third sacral lamina was fractured and displaced into the spinal canal, but vertebral body did not displace. The fr...

Previous work of our laboratory has shown that neurons in the lateral sacral cord in cat project heavily to the periaqueductal gray (PAG), in all likelihood conveying information from bladder and genital organs. In humans this information usually does not reach consciousness, which raises the question of whether the lateral sacral cell group projects to the thalamus. After wheatgerm agglutinin-...

404 CMYK Sir, An anterior sacral meningocele is a cerebrospinal fluid-filled unilocular or multilocular extension of the duramater and arachnoid mater out of the spinal canal through a defect either in the anterior sacral wall or antero-laterally through an enlarged vertebral foramen or coalesced foramina into the pelvic retroperitoneal and infraperitoneal space. Since its description by Bryant...

Sacral insufficiency fractures are a more commonly recognized cause of spine pain among osteoporotic patients, and are now treatable by sacroplasty using percutaneous instillation of PMMA cement. Sacroplasty may be performed using only fluoroscopic landmarks; however, the bony anatomy of the sacrum is complex and the cement deposition based on these landmarks has not been specifically confirmed...

Background & Aim: Tethered spinal cord is the most prevalent anatomical deformity, usually diagnosed in childhood. The present study aimed to describe the different anatomo-radiological patterns of the tethered spinal cord with lipoma. Methods & Materials/Patients: We conducted a retrospective descriptive study in the Neurosurgery Department of General Grand Yoff Hospital and the Neurosurgical...

background and aim: one of the key aspects of maternal care is observing the progress of labor. careful assessment of labor progress could provide mothers to be referred on time and could decrease the maternal and neonatal morbidity. this study aimed to compare diagnostic accuracy of purple line with transvers diagonal of michaelis sacral rhomboid to predict labor progress in nulliparous and mu...
