Abstract
PURPOSE To review outcomes of spinopelvic dissociation treated with open lumbopelvic fixation. METHODS We reviewed all cases of spinopelvic dissociation treated at three Level-I trauma centers with open lumbopelvic fixation, including those with adjunctive percutaneous fixation. We collected demographic data, associated injuries, pre- and postoperative neurologic status, pre- and postoperative kyphosis, and Roy-Camille classification. Outcomes included presence of union, reoperation rates, and complications involving hardware or wound. RESULTS From an initial cohort of 260 patients with spinopelvic dissociation, forty patients fulfilled inclusion criteria with a median follow-up of 351 days. Ten patients (25%) had a combination of percutaneous iliosacral and open lumbopelvic repair. Average pre- and postoperative kyphosis was 30 degrees and 26 degrees, respectively. Twenty patients (50%) had neurologic deficit preoperatively, and eight (20%) were unknown or unable to be assessed. All patients presenting with bowel or bladder dysfunction (n = 12) underwent laminectomy at time of surgery, with 3 patients (25%) having continued dysfunction at final follow-up. Surgical site infection occurred in four cases (10%) and wound complications in two (5%). All cases (100%) went on to union and five patients (13%) required hardware removal. CONCLUSION Open lumbopelvic fixation resulted in a high union rate in the treatment of spinopelvic dissociation. Approximately 1 in 6 patients had a wound complication, the majority of which were surgical site infections. Bowel and bladder dysfunction at presentation were common with the majority of cases resolving by final follow-up when spinopelvic dissociation had been treated with decompression and stable fixation.

Spinopelvic Dissociation: A Systematic Review and Meta-analysis. J Am Acad Orthop Surg 2021; 29:e198-e207.

Abstract
INTRODUCTION Spinopelvic dissociation is a rare type of injury which occurs in approximately 2.9% of pelvic disruptions and correlates with high-energy trauma.The purpose of this study was to systematically evaluate the incidence, demographics, treatment, clinical outcome, and complication rate associated with these injuries. METHODS A literature review on Medline, PubMed, and Google was performed. Overall, 216 abstracts were reviewed in English, German, and French, of which 50 articles were included. RESULTS Within the 50 studies, 19 publications were case reports and 16 were case series with low-level evidence. Overall, 379 patients with spinopelvic dissociation were identified at a mean age of 31.6 ± 11.6 years and an injury severity score of 23.1 ± 3.8 between 1969 and 2018. Most cases were related to fall from heights (55.7%), followed by road accidents (28.5%). Two hundred fifty-eight patients (68.1%) showed neurologic impairment at initial presentation, which improved in 65.1% after surgery. The treatment of choice was surgery in 93.1% of cases with triangular fixation in 68.8%. Regardless of the technique, the healing/fusion rate was 100% with a complication rate of 29.9% (n = 96/321). CONCLUSION Spinopelvic dissociation is a rare type of injury with limited data in the literature. Based on our review, it is possible that a streamlined, evidence-based algorithm may improve care for these difficult patients. LEVEL OF EVIDENCE II. STUDY DESIGN Systematic Review.

Abstract
EPIDEMIOLOGY Traumatic fractures of the pelvic ring are relatively rare, but are associated with increased risk of mortality. Depending on injury mechanism and main vector of energy impact, a distinction is made between anteroposterior compression, lateral compression, and vertical shear (Young and Burgess classification), while the stability-related classification according to Tile distinguishes between type A (stable), type B (rotationally unstable) and type C (completely unstable). A comprehensive modern classification is given by the AO/OTA. RADIOLOGICAL FRACTURE DIAGNOSIS Plain pelvis x‑rays lack sufficient sensitivity but are still used to detect highly unstable pelvic fractures. CT has superior sensitivity and specificity. In addition to fracture classification, CT allows reliable assessment of associated vascular and bladder/urethral injuries and large soft tissue hemorrhage. MRI is unparalleled in showing bone marrow edema, cauda and plexus complications, and peripelvic soft tissue damage. MRI may also prove to be a valuable diagnostic tool for pelvic ring injuries in children, adolescents and young women, provided they are hemodynamically stable. Angiography, ultrasonography and bone scintigraphy are additional important diagnostic and therapeutic options. PRACTICAL RECOMMENDATIONS Knowledge of basic pelvic trauma mechanisms is important to understand the potential severity of traumatic pelvic fractures and to classify them correctly in terms of stability. Being familiar with typical concomitant injuries in pelvic ring fractures allows reliable diagnosis and their communication with the clinician. CT remains the "diagnostic workhorse". In fragile pelvic fractures, the often prolonged course with fracture progression must be taken into account, which is why MRI is of particular importance herein.

Abstract
Sacral fractures are a heterogeneous group of fractures occurring in young people following road traffic accidents and falls from height, or in the elderly with osteoporosis following trivial trauma.This heterogeneity, combined with the low incidence of sacral fractures, determines a lack of experience amongst physicians, often leading to misdiagnosis, underestimation and inadequate treatment. The diagnosis should be made by assessing specific features during the clinical presentation, while computed tomography (CT) scan continues to be the choice of investigation.Sacral fractures can be treated non-operatively or surgically. Non-operative treatment is based on rest, pain relief therapy and early mobilization as tolerated. Surgical techniques can be split into two main groups: posterior pelvic fixation techniques and lumbopelvic fixation techniques. Anterior pelvic fixation techniques should be considered when sacral fractures are associated with anterior pelvic ring injuries, in order to increase stability and reduce the risk of posterior implant failure. To improve fracture reduction, different solutions could be adopted, including special positioning of the patient, manipulation techniques and use of specific reduction tools. Patients suffering from spinopelvic dissociation with associated neurologic lesions hardly ever recover completely, with residual lower-limb neurologic sequelae, urinary problems and sexual disfunction.Herein, we present issues, challenges and solutions related to the management of sacral fractures.

Abstract
BACKGROUND The purpose of this study was to evaluate the clinical outcomes of isolated decompression for patients with transverse sacral fractures and cauda equina syndrome, which have been rarely reported before. MATERIAL AND METHODS Twelve neurological impaired patients with transverse sacral fracture from January 2010 to March 2017 treated in our institution were evaluated. All patients went through isolated decompression and were followed for a minimum of 12 months. Fracture causes, classifications, associated injury, radiologic results, clinical outcomes using the Majeed index, and neurological outcomes using the Gibbons criteria were evaluated. RESULTS Motor vehicle accidents and falling injuries were the major causes of trauma. The average time from trauma to surgery was 89.8 days. Eleven patients underwent laminectomy with no more than 3 segments resected and 1 patient had S1-S4 excised. Three patients with fracture involving the lumbopelvic joint had L5 laminectomy. All patients achieved bony union, with 7 patients (63.6%) showing satisfactory pelvic outcome. Average Gibbons scores improved from 2.8 to 1.9 at 18-month average follow-up, but most patients were left with residual pain. No surgical-related complications were seen in any patients. CONCLUSIONS Isolated decompression can be considered for patients who present a stable sacrum with non-displaced fracture or an old fracture that shows fracture healing. Favorable pelvic outcomes and neurological recovery, along with acceptable stability, can be acquired.
