anaesthetic solution in the sacral canal bathing the peridural space. Development of sacral anesthesia.?In 1901, Sicard and Cathelin introduced and developed the technique of extradural injection by introduction of cocaine solution into the sacral canal. It was several years afterwards that the practical application of this method in surgery and obstetrics was found. By 1920, 4,200 cases were t...

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...

Sacral stress fractures are common in elderly people. However, sacral stress fracture should be always screened in the differential diagnoses of low back pain during the postpartum period. We present a case of sacral fracture in a thirty-six-year-old woman with low back pain and severe right buttock pain two days after cesarean section delivery of a 3.9 Kg baby. The diagnosis was confirmed by M...

PURPOSE A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. METHODS Eight patients were treated in our ...

Sacral fractures in elderly patients with associated lumbosacral lesions can be overlooked easily because of vague symptoms and delayed neurological insufficiency. A 70-year-old female and a 73-year-old female presented with delayed neurological insufficiency caused by transverse sacral fracture after minor trauma. Both patients had suffered from lower extremity symptoms with dysuresia and dysc...

INTRODUCTION In reviewing a larger group of osteoporotic vertebral compression fractures (VCFs), we found that the overall incidence of sacral insufficiency fractures (SIFs) is higher than commonly reported values. This is especially seen in patients with previous or concurrent lumbar VCFs and also in a subgroup that had lumbar stenosis or hip arthroplasty. The altered biomechanics due to assoc...

BACKGROUND We aimed to explore the prognosis and risk factors influencing tumor recurrence in surgery-treated patients with primary sacral tumors. METHODS Fifty-six patients between February 2011 and December 2016 in Yishui Central Hospital with primary sacral tumors were selected and treated with radical surgeries. The perioperative outcomes and postoperative neurological functions were obse...

Context : The sacrum generally is composed of five vertebrae fused to form a triangular bony mass with four pairs of sacral foramina. The sacrum may contain six vertebrae, by development of an additional sacral element or by incorporation of the fifth lumbar or first coccygeal vertebrae produces five pairs of sacral foramina. Sacralization is entirely undiagnosable without an X-ray examination ...

BACKGROUND It has been suggested that the effects of sacral nerve stimulation against fecal incontinence involve neuromodulation at spinal or supraspinal levels. OBJECTIVE This study aims to investigate the afferent sensory pathways from the anorectum before and during sacral nerve stimulation. DESIGN This is an explorative study. PATIENTS Fifteen women with idiopathic fecal incontinence ...

Intraspinal schwannomas localized in the sacrum are relatively infrequent, accounting for 1-5% of all spinal axis schwannomas. They frequently grow to considerable size before detection; hence, the term giant sacral schwannoma. Sacral schwannomas arise from the sacral nerve roots. The diagnosis of schwannomas in the spinal canal is difficult because of their slow growth, often resulting in exte...
