The pelvis is one of the most stressed areas of the human musculoskeletal system due to the transfer of truncal loads to the lower extremities. Sacroiliac joint injury may lead to abnormal joint mechanics and an unstable pelvis. Various fixation techniques have been evaluated and discussed. However, it may be difficult to investigate each technique due to variations in bone quality, bone anatomy, fracture pattern, and fixation location. Additionally, the finite element method is one useful technology that avoids these variations...

We describe a case of fat droplets and blood in the cerebral subarachnoid space secondary in a patient with a complex sacral fracture without associated cranial trauma, a few days after admission. To our knowledge, there is only one published case with similar findings and without any other underlying lesion as cause. We explain the differences in the mechanism of production between this direct fat embolism and brain fat embolism syndrome, which is an intravascular embolism with different radiological appearance...

BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...

Sacral fracture with spino-pelvic  dissociation is a rare and unstable injury caused by high-energy trauma, often with serious haemodynamic and neurological implications. Diagnosis is easily delayed or missed as it is often masked by severe associated injuries. Here, we present an unusual case of spino-pelvic dissociation sustained during a seizure episode in a young epileptic patient on long-term anticonvulsant therapy with previous thoracolumbar spinal arthrodesis. This unique case brings to light the need for clinicians to consider sacral fractures in patients presenting with low back pain with no preceding trauma who otherwise may have risk factors for pathological fractures...

BACKGROUND CONTEXT: Complex sacral fractures with vertical and anterior pelvic ring instability treated with traditional fixation methods are associated with high rates of failure and poor clinical outcomes. Supplemental lumbopelvic fixation (LPF) has been applied for additional stability to help with fracture union. PURPOSE: The study aimed to determine whether minimally invasive LPF provides reliable fracture stability and acceptable complication rates in cases of complex sacral fractures...

The standard of care for treatment of sacral insufficiency fracture (SIF) remains conservative management with limited weight-bearing and analgesics, as most fractures heal within 12 weeks. For those who fail to respond to conservative therapy, are immobile, or cannot tolerate the pain despite analgesic therapy, as well as those who do not improve with time, rest, or activity modification, minimally invasive surgery with percutaneous transverse screw fixation across the fracture is effective. However, a less invasive procedure, percutaneous sacroplasty, may be an option for potential rapid pain reduction...

A 19-year-old male military recruit presented with 3 weeks of persistent left hip and groin pain after abnormally twisting his hip during a hike. Initial radiographs were interpreted as negative. He subsequently underwent a bone scan which revealed linear left sacral uptake along or paralleling the sacroiliac joint. Differential diagnostic considerations included unilateral sacroiliitis and sacral fracture. SPECT/CT was performed which confirmed left sacral fatigue stress fracture. Transitional lumbosacral anatomy was evident on radiographs with pseudoarticulation of the transitional left S1 transverse process with the sacrum...

INTRODUCTION: A sacral insufficiency fracture (SIF) often manifests as low back pain or sciatica in the absence of any antecedent trauma. These fractures may be missed because of lack of appropriate imaging. The purpose of this study was to clarify the incidence and clinical features of SIF as well as the characteristic findings on magnetic resonance imaging (MRI) of the lumbar spine. MATERIALS AND METHODS: The study participants comprised 250 patients (132 male, 118 female; mean age 58...

BACKGROUND CONTEXT: Trans-sacral implants are increasingly used to treat fractures of the sacrum, especially for osteoporosis-associated fragility fractures. However, the complex and highly variable sacral anatomy limits their use. It is still not clear which morphologic characteristics are critical to determine the availability and dimensions of trans-sacral corridors. PURPOSE: This study aims to assess sacral anatomy and its influence on trans-sacral corridors...

Osteoporotic fractures of the sacrum usually involve the sacral ala and can be managed with percutaneous cementoplasty if conservative therapy failed to achieve bone consolidation. On the other hand, isolated transverse fractures of the lowest sacrum are more rare, with little literature focusing on their management in the osteoporotic population. If pseudoarthrosis occurs in this location, sacroplasty is not an optimal therapeutic option because of the poor biomechanical resistance of cement to multi-directional stresses...

BACKGROUND: Stress injuries (stress fractures and stress reactions) of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. These injuries can be detected by bone marrow edema lesion on MRI. However, little is known about the prevalence and clinical features of early stage lumbosacral stress injuries. This study aimed to evaluate the epidemiology of lumbosacral stress injuries. METHODS: A total of 312 patients (under 18 years of age) who complained of sports-related lower back pain that had lasted for ≥7 days underwent magnetic resonance imaging (MRI) scans...

PROBLEM AND HYPOTHESIS: Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain. PATIENTS AND METHODS: Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.3) that had healed were included. Foreign patients and those with an associated spinal or acetabular fracture or nonunion were excluded...

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 associated lumbar stenosis or hip arthroplasty lead to increased mechanical stress on already weakened and deficient sacral alae, which are more vulnerable to osteoporotic weakening than other parts of the sacrum...

BACKGROUND: Although internal fixation is the definitive treatment in unstable pelvic fractures with disruption of the anterior arch and a vertical fracture of the sacrum (AO type C1.3), there have been no agreement of the best technique of internal fixation yet. We aimed to derive comparable objective data on stiffness and load to failure in this type of fracture fixations. METHODS: Synbone was modified into AO type C1.3 fracture model, while treatments were divided into six internal fixation treatment groups using tension band plate (TBP), symphysis pubis plate (SP) with iliosacral screw at S1 and S2 (IS S1-S2), pubic screw (PS) with iliosacral TBP, PS and IS S1-S2, SP and IS S1-S3, PS and S1-S3 and finally PS and IS S1-S3...
