Article Abstract
Objectives: Posterior iliac crescent fracture with associated sacroiliac joint disruption (PICFSID) is a type of traumatic posterior pelvic injury associated with instability. Posterior iliac fracture location and obliquity along with other details determine the treatment. Open reduction and internal fixation has been previously recommended for the majority of crescent fractures. Our objectives were to determine whether all crescents can be categorised according to the previously described Day crescent classification scheme, and to see which crescent types are amenable to percutaneous fixation.
Patients And Methods: We identified 129 crescents in 128 patients during a 7-year time period. Of these, 100 patients met the inclusion criteria of at least 3 months of clinical and radiographic follow-up. There were 57 males and 43 females, with a mean age of 42 years and a mean injury severity score of 25.5. Treatment selection was based on fracture type and overall patient factors and consisted of non-operative management, pelvic external fixation, open reduction and internal fixation, and closed reduction and percutaneous iliosacral screw fixation.
Results: There were 16 Type I, 47 Type II and 37 Type III crescent fractures. Twelve injuries could not be classified according to the Day scheme. Percutaneous iliosacral screw fixation was utilised in 60% of all crescents after either closed or open reduction of the PICFSID.
Conclusions: The majority of PICFSIDs are amenable to closed reduction and percutaneous iliosacral screw fixation. The Day classification for PCIFSID should be expanded to include variant injury patterns.

Article Synopsis
- Fragility pelvic fractures are becoming more common due to increased life expectancy, often requiring surgery with ilio-sacral screws for stabilization.* -
- This review discusses a novel, low-cost cement augmentation technique for ilio-sacral screws, designed for patients with poor bone quality and includes case examples from five patients treated between 2017 and 2024.* -
- The new surgical method is straightforward and uses readily available instruments, but further research is needed to prove its efficacy compared to traditional techniques without cement augmentation.*

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.

Purpose: Posterior pelvic ring lesions are a common finding in patients with pelvic trauma, representing a challenging condition for trauma surgeons. Surgical options are different and there is not yet evidence about the best option. Aim of the study are: (i) to compare Lumbopelvic fixation (LPF) and ilio-sacral screw fixation (ISS) regarding clinical and radiological outcome in unstable posterior pelvic ring injuries, both as whole population and single similar fracture types according to Tile classification (C1vsC1, C2vsC2, C3vsC3); (ii) to analyze clinical outcomes and complications in lumbopelvic fixation group, comparing open and closed reduction technique.

Operative treatment of fragility fractures of the pelvis has become a gold standard. Preoperative planning, including the assessment of the pathway for iliosacral screws, is crucial. The anchorage of the screw depends on the bone quality.

Background: Determining the proper iliosacral screw orientation in a dysmorphic S1 sacral segment using a C-arm is difficult, and pelvic computed tomography (CT) is often necessary for the preoperative planning. On the preoperative pelvic axial CT section, the intended screw trajectory can be delineated intraosseously along the axis of the oblique osseous corridor. An inherently accurate orientation would be determined by 2 factors: (1) the trajectory is in the pelvic transverse plane, and (2) it is oriented relative to the coronal plane at a patient-specific angle, which should be measured preoperatively.
