Functional and Radiological Outcome of Anterior Plate Stabilisation of the Sacroiliac Joint in Unstable Pelvic Injury.

Introduction: Sacroiliac joint disruption, resulting from high energy trauma can cause significant morbidity if no proper treatment given. Many techniques can be used to stabilise pelvic ring injuries. We studied the functional and radiological outcome following open reduction and anterior fixation of the sacroiliac joint and agreement between both outcomes.

Comparison of two surgical treatment strategies for fragility fractures of the pelvis based on early postoperative mobility outcomes using insole force sensors.

Introduction: Increasing incidences for fragility fractures of the pelvis (FFP) have been reported and surgical treatment remains demanding. While conventional screw osteosynthesis is a common method, complications may arise due to altered bone morphology in the osteoporotic pelvic bone. The iFuse implant system is a novel implant, first introduced for treatment of degenerative sacroiliac joint dysfunction, which offers promising biomechanical characteristics with potential benefits for treatment of FFP.

Safe corridors for sacroiliac fixation in pediatric patients.

Introduction: Pelvic ring fractures are rare in the pediatric population and can be treated using sacroiliac screws when needed. The aim of this study was to identify safe anatomical corridors for sacroiliac fixation in different pediatric age groups and also to determine the prevalence of sacral dysmorphism in the study sample.

Method: We measured the dimensions of the horizontal and oblique S1 corridors and the horizontal S2 corridor in pelvic computed tomography scans of 138 children aged 1 to 16 years.

Impact of sacroiliac interosseous ligament tension and laxity on lumbar spine biomechanics under vertical vibration: a finite element study.

Objective: To investigate the impact of tension and laxity in the sacroiliac interosseous ligament on lumbar spine displacement and force response in vibration environments.

Methods: A finite element model of the lumbar-pelvis, previously crafted and rigorously validated, was used to simulate ligament tension and laxity by adjusting the elastic modulus of the SIL under a sinusoidal vertical load of ±40 N at 5 Hz. Comparisons of lumbar spine horizontal and axial displacements as well as annulus fibrous stress, nucleus pulposus pressure, and facet joint force were performed, respectively.

New Minimally Invasive Method for Treating Posterior Pelvic Ring Fractures: Biomechanical Validation and Clinical Application of Sacroiliac Joint Locking Plate.

Objective: Considering the high incidence and complexity of unstable posterior pelvic ring fractures, and the need for less invasive and more effective treatment options, this study aims to introduce a novel minimally invasive, safe, and simple internal fixation method for the treatment of unstable posterior pelvic ring fractures using the sacroiliac joint locking plate (SJP) system, and to provide biomechanical validation and clinical evaluation of this method.

Methods: Biomechanical research was conducted using standard pelvic bone models from Synbone, Switzerland, to create Denis II zone unstable posterior pelvic ring fracture models, and to assess the stability of the SJP under different loads compared with traditional fixation methods. A retrospective clinical study analyzed the clinical efficacy of SJP treatment in 62 patients (mean age of 51.

A Misplaced S2 Alar-Iliac Screw Causing L5 Spinal Nerve Injury: A Report of a Rare Case.

Although neurovascular structures, including the superior gluteal artery, sciatic nerve, obturator nerve, internal iliac vein and artery, and lumbosacral plexus, are at risk when S2 alar-iliac (S2AI) screws are used, no cases of nerve injuries have been reported. An 84-year-old man was referred to our institute with persistent left sciatica for seven months after undergoing salvage surgery using S2AI screws for deep surgical site infection from a previous posterior interbody fusion surgery at L5-S1. Based on the radiographic and diagnostic selective nerve root block findings, a diagnosis of left L5 radiculopathy was suspected due to the left S2AI screw being caudally misplaced and severely protruding into the pelvic cavity.

Severe multiple injuries in a 15-year-old boy with pelvic fracture complete anterior dislocation of the sacroiliac joint and rupture of the internal and external iliac arteries: A case report of a rare injury.

Rationale: Anterior dislocation of the sacroiliac joint combined with pelvic fractures is relatively rare in clinical practice. It is often associated with hemodynamic instability and severe injuries to other regions, resulting in a complex condition, prolonged treatment duration, and high rates of mortality and disability. However, there are few reports in the literature describing the diagnosis and treatment of anterior dislocation of the sacroiliac joint.

Stabilization of 82 sacroiliac luxations in 67 cats using two sacroiliac screws (2014-2023).

Objective: To describe sacroiliac luxation stabilization in cats using two screws and to report clinical and radiographic short-term outcomes.

Study Design: Retrospective clinical cohort study.

Sample Population: Cats (n = 67) with sacroiliac luxation.

Anterior Sacroiliac Fracture Dislocation: A Comparative Radiologic analysis of Crescent Fractures in Pelvic Ring Injuries: A Retrospective Study.

: Anterior sacroiliac fracture dislocation (ASFD), also known as locked pelvis, is a rarely reported diagnosis. The types of ASFDs are often misdiagnosed as lateral compression fractures due to the presence of crescent fractures. In this study, we distinguished ASFD from lateral compression fractures (LC 2) and studied their characteristics.
