Fragility Fractures of the Pelvis (FFP)

Fragility fractures of the pelvis (FFP) are an increasingly common complication of osteoporosis in older adults and are associated with substantial morbidity, loss of independence, and mortality. Despite their clinical impact, FFP remain underdiagnosed, particularly sacral fractures, and their management varies considerably across centers.FFP-France is a French multicenter ambispective observational study designed to describe functional outcomes in adults aged 60 years and older with FFP. The primary objective is to assess functional outcome at 6 months using the Parker Mobility Score. Secondary objectives include describing clinical and radiological characteristics, diagnostic and therapeutic management, pain, autonomy, mortality, osteoporosis management, and factors associated with unfavorable functional recovery.

This prospective randomized controlled trial aims to compare the efficacy and safety of robot assisted minimally invasive treatment versus conventional surgery in elderly patients with FFP3-4 fragility fractures of the pelvis. Eligible patients will be stratified according to FFP classification and randomly assigned in a 1:1 ratio to receive either robot assisted minimally invasive fixation or conventional surgical treatment. Primary and secondary outcomes include pain relief, early mobilization, functional recovery, perioperative complications, venous thromboembolism events, laboratory parameters, imaging outcomes, and healthcare resource utilization. The study aims to provide evidence for optimizing surgical treatment strategies in elderly patients with unstable pelvic fragility fractures.

Fragility fractures of the pelvic ring are a common injury associated with poor patient outcomes and high healthcare costs. Management of these injuries is evolving with increasing frequency of operative stabilization of the pelvic ring, despite a lack of evidence supporting operative versus nonoperative treatment. This multicenter prospective cohort study will evaluate 120 patients to determine the feasibility of a randomized controlled trial comparing operative and nonoperative treatment, by evaluating patient willingness to enroll in a trial, surgeon willingness to randomize their patients' treatment, and the completeness of data collection.

This prospective randomized controlled trial aims to compare the efficacy and safety of robot assisted minimally invasive treatment versus conservative treatment in elderly patients with FFP1-2 fragility fractures of the pelvis. Eligible patients will be stratified according to FFP classification and randomly assigned in a 1:1 ratio to receive either robot assisted minimally invasive fixation or standardized conservative treatment. Primary and secondary outcomes include pain relief, functional recovery, fracture progression, venous thromboembolism events, complications, and healthcare resource utilization. The study aims to provide evidence for optimizing treatment strategies in elderly patients with pelvic fragility fractures.

Multicenter, snapshot cohort studies or audits have the ability to gather large patient numbers in short time periods from many healthcare systems with different resources or practices of care concerning one specific surgical condition. This type of studies allows exploration of differences in patient populations and management across the sampled cohort to identify areas of practice variability that may result in apparent differences in outcome. As such, whilst not providing true evidence of efficacy or the impact of a single variable on overall outcome, these studies can be hypothesis-generating and identify areas warranting further study in future randomized controlled trials (1). Snapshots also shed light on the real world practice, rather than the presumed or guideline suggested patient care (2). Traumatic Pelvic Ring Injuries (TPRI) represent a broad spectrum of trauma-associated pathologies with a distinct bimodal age distribution in patients admitted through the Emergency Departments of all acute care hospitals. In younger patients, this type of injury is often associated with high-energy trauma, hemodynamic instability, high mortality and morbidity rates (3-6). In the elderly population, pelvic fractures result from low energy trauma mechanisms (e.g. ground level fall) and can affect the long-term independency and life quality of geriatric patients (7). There is substantial variation in the management of pelvic ring injuries among pelvic trauma surgeons; these variations include but are not limited to the timing of definitive fixation, the indications and protocols of conservative treatment, and the appropriate osteosynthesis of the anterior and/or posterior pelvic fractures (8). This 'ESTES snapshot audit' -a prospective observational cohort study- has a dual purpose. Firstly, as an epidemiological study, it aims to report the burden of injury in specific hospitals, distributed widely throughout Europe. Secondly, this study aims to demonstrate current strategies for both, younger (after high-energy trauma) and geriatric patients (after low-energy trauma) employed to assess and treat these patients. These twin aims will serve to provide a 'snapshot' of current medical practice, but will also be hypothesis-generating while providing a rich source of patient-level data to allow further analysis of particular clinical questions. The acquired study data can be subsequently evaluated and compared to patient data of established pelvic trauma registries across Europe.
