Optimizing Outcomes after Operative Treatment Bicondylar Tibial Plateau Fractures - Time for Innovation?

Bicondylar tibial plateau fractures are technically demanding fractures that have a high complication rate. We sought to review the recent literature with the aim to summarize the development of new classification systems that may enhance the surgeon's understanding of the fracture pattern and injury. We highlight the best methods for infection control and touch on new innovative solutions using 3D printer models and augmented mixed reality to provide potentially personalized solutions for each specific fracture configuration.

Accuracy of FAST in detecting intraabdominal bleeding in major trauma with pelvic and/or acetabular fractures: a retrospective cohort study.

PURPOSE: The Focused Assessment with Sonography for Trauma (FAST) is a tool to rapidly detect intraabdominal and intrapericardial fluid with point-of-care ultrasound. Previous studies have questioned the role of FAST in patients with pelvic fractures. The aim of the present study was to assess the accuracy of FAST to detect clinically significant intraabdominal hemorrhage in patients with pelvic fractures. METHODS: We included all consecutive patients with pelvic and/or acetabular fractures treated our Level 1 trauma center from 2009-2020. We registered patient and fracture characteristics, FAST investigations and CT descriptions, explorative laparotomy findings, and transfusion needs. We compared FAST to CT and laparotomy findings, and calculated true positive and negative findings, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: We included 389 patients. FAST had a sensitivity of 75%, a specificity of 98%, a PPV of 84%, and a NPV of 96% for clinically significant intraabdominal bleeding. Patients with retroperitoneal hematomas were at increased risk for laparotomy both because of True-negative FAST and False-positive FAST. CONCLUSION: FAST is accurate to identify clinically significant intraabdominal blood in patients with severe pelvic fractures and should be a standard asset in these patients. Retroperitoneal hematomas challenge the FAST interpretation and thus the decision making when applying FAST in patients with pelvic fractures.

Ogilvie Syndrome in Patients With Traumatic Pelvic and/or Acetabular Fractures: A Retrospective Cohort Study.

OBJECTIVES: To assess the incidence, risk factors, and clinical outcomes of Ogilvie syndrome (OS) in patients with pelvic and/or acetabular fractures. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS: One thousand sixty patients with pelvic and/or acetabular fractures treated at Rigshospitalet, Copenhagen, between 2009 and 2020. INTERVENTION: Interventions comprised the treatment of pelvic and/or acetabular fractures with emergency external and/or internal fixation. MAIN OUTCOME MEASUREMENTS: Outcomes included diagnosis of OS, perioperative complications, ICU stay and length, length of admission, and mortality. RESULTS: We identified 1060 patients with pelvic and/or acetabular fractures. Of these, 25 patients were diagnosed with OS perioperatively, corresponding to incidences of 1.6%, 2.7%, and 2.6% for acetabular, pelvic, and combined fractures, respectively. Risk factors included congestive heart failure, diabetes, concomitant traumatic lesions, head trauma, fractures of the cranial vault and/or basal skull, retroperitoneal hematomas and spinal cord injuries, and emergency internal fixation and extraperitoneal packing. Six (24%) patients underwent laparotomy, and all patients had ischemia or perforation of the cecum for which right hemicolectomy was performed. Ogilvie syndrome was associated with a significant increase in nosocomial infections, sepsis, pulmonary embolism, ICU stay, and prolonged hospital admission. CONCLUSION: Ogilvie syndrome in patients with pelvic and/or acetabular fractures is associated with increased risk of perioperative complications and prolonged hospital and ICU stays, resulting in an increased risk of morbidity and mortality. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Lower urinary tract injuries in patients with pelvic fractures at a level 1 trauma center - an 11-year experience.

BACKGROUND: Urological injuries can occur in patients with pelvic fractures. Treatment recommendations lack solid evidence and is often pragmatical. There is a continuous need to describe short- and long-term morbidity following lower urinary tract trauma. OBJECTIVE: To describe incidence, diagnosis, treatment, and morbidity following lower urinary tract injuries in pelvic fractures. PATIENTS AND METHODS: Retrospective study including patients with pelvic, including acetabular, fractures admitted to a Level I Trauma Centre covering 2.8 million citizens between 2009 and 2020. Outcome measurements comprised primary management, treatment trajectory, short- and long-term complications and outcomes. RESULTS: A total of 39 (5%) patients with pelvic fractures had concomitant urethral and/or bladder injuries, and one patient with an acetabular fracture had a bladder injury. The management of urethral injuries varied vastly, and complete urethral ruptures were associated with severe short- and long-term complications. Only one patient with bladder injury experienced severe long-term complications. CONCLUSIONS: Management of lower urinary tract injuries in patients with major pelvic fractures remains a major challenge. Special attention should be focused on urethral injuries where we uncovered an unsystematic treatment and follow-up even in a highly experienced centre, although this is also attributed to complicated multidisciplinary patient trajectories. There is a continuous need to reduce long-term complications following urethral trauma which should be addressed in multicenter studies.

Plate-assisted Bone Segment Transport With Motorized Lengthening Nails and Locking Plates: A Technique to Treat Femoral and Tibial Bone Defects.

This article describes a new bone transport technique for femoral and tibial bone defects using lengthening nails combined with locking plates. We term it plate-assisted bone segment transport (PABST). METHODS: Nine patients with five femoral and four tibial bone defects from open fractures or malignancies were treated between 2016 and 2018. Mean femoral defect length was 9.3 cm (range 7 to 11.5). Mean tibial defect was 8.9 cm (range 4.8 to 15). The patients were evaluated for time to weight bearing, consolidation index, mechanical axis deviation, and limb length discrepancy. RESULTS: Seven of nine patients have fully consolidated. The mean consolidation time was 6.6 months. The consolidation index was 0.9 (femur) and 1.26 (tibia) mo/cm. Two patients required supplementary lengthening. One patient had mild varus, one mild valgus; the remainder had a normal mechanical axis. Limb length discrepancy remained acceptable in all patients. The main complications were heterotopic ossification, delayed healing, and reduced knee motion. CONCLUSION: Bone transport with lengthening nails and locking plates is an effective and patient-friendly way of treating bone defects, eliminating the adverse effects of external fixation and reducing treatment time. The plate provides stability during transport and docking; it can address concomitant fractures and facilitates acute shortenings.

The cost of infection in severe open tibial fractures treated with a free flap.

PURPOSE: Open tibial fractures needing soft tissue cover are challenging injuries. Infection risk is high, making treatment difficult and expensive. Delayed skin closure has been shown to increase the infection rate in several studies. We aimed at calculating the direct and indirect cost of treatment, and to determine the effect of delayed skin closure on this cost. METHODS: We reviewed all records of patients treated with a free flap in our institution for an open tibial fracture from 2002 to 2013. We calculated direct costs based on length of stay (LOS) and orthopaedic and plastic surgical procedures performed, including medications and intensive care. We analysed indirect cost in terms of absenteeism and unemployment benefits. The primary goal was to establish the extra cost incurred by an infection. RESULTS: We analysed 46 injuries in 45 patients. Infection increased the LOS from 41 to 74 days and increased the cost of treatment from € 49,817 in uninfected fractures to € 81,155 for infected fractures. Employed patients spent 430 days more on unemployment benefits, than a matched cohort in the background population. Achieving skin cover within seven days of injury decreased the infection rate from 60 to 27 %. CONCLUSIONS: Severe open tibial fractures covered with free flaps, cause over a year of absenteeism. Infection increases direct cost of treatment over 60 % and roughly doubles LOS. Early soft-tissue cover and correct antibiotics have been shown to improve outcomes-underscoring the need for rapid referral to centres with an ortho-plastic set-up to handle such injuries.
