Pelvic fixation remains one of the main challenging issues in non-ambulatory neuromuscular scoliosis (NMS) patients, between clinical effectiveness and a high complication rate. The objective of this multicenter and retrospective study was to evaluate the outcomes of a technique that was applied to treat 173 NMS patients. The technique is not well-known but promising; it uses the ilio-sacral screw, combined with either the posterior spinal fusion or fusionless bipolar technique, with a minimum follow-up of two years. The mean operative age of the patients was 13 ± 7 years. The mean preoperative main coronal curve was 64° and improved by a mean of -39° postoperatively. The mean preoperative pelvic obliquity was 23°, which improved by a mean of -14° postoperatively. No decrease in the frontal or sagittal correction was observed during the last follow-up. The sitting posture improved in all cases. Twenty-nine patients (17%) had a postoperative infection: twenty-six were treated with local debridement and antibiotics, and three required hardware removal. Fourteen mechanical complications (8%) occurred: screw malposition ( = 6), skin prominence ( = 1), and connector failure ( = 1). This type of surgery is associated with a high risk for infection. Comorbidities, rather than the surgery itself, were the main risk factors that led to complications. The ilio-sacral screw was reliable and effective in correcting pelvic obliquity in NMS patients. The introduction of intraoperative navigation should minimize the risk of screw misplacement and facilitate revision or primary fixation.

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.*

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.

Article Synopsis
  • A new technique for percutaneous ilio-sacral screw (ISS) insertion was introduced to address challenges and high malposition rates associated with traditional methods using C-arm fluoroscopy.
  • This study compared two groups of patients: one using the traditional dual-plane method and the other using the newly proposed method, analyzing factors like malposition rate, radiation exposure, and operating time.
  • Results showed that the new method significantly reduced the average operation time and fluoroscopy applications, with only 10.7% of screws mispositioned, indicating improved accuracy over the traditional method.

Navigation and 3D-imaging in pelvic ring surgery: a systematic review of prospective comparative studies.

Background: Few literature reviews have been published focusing on navigation, robotic or pre-operative planning using 3D-imaging technology (3D-printing, 3D-planning). To our knowledge, no reviews have been performed to assess and compare all these modalities together versus control groups (conventional fluoroscopy) through high Randomized Control Trials (RCTs) and Prospective Control Studies (PCSs). The aim of this study was to assess and compare 3D-imaging technologies from pre-operative planning to per-operative navigation and robotic in the management of pelvic ring fractures through high level studies.

Purpose: The insertion of ilio-sacral (IS) screws for distal anchoring in the instrumentation of pediatric neuromuscular scoliosis (NS) presents a significant challenge, often leading to elevated rates of complications. Utilizing computed tomography (CT) navigation and preoperative planning technology is proposed as a potential solution to mitigate these challenges. This study aims to assess the precision of IS screw placement through CT-graphic measurements, both with and without preoperative planning, followed by navigated IS screw insertion, in pediatric neuromuscular scoliosis.
