    Octogenarian and Nonagenarians Are at a Higher Risk for Experiencing Adverse 30-Day Outcomes Following ORIF of Ankle Fractures
    (Sage, 2021-05-04) Gray, Mitchell T.; Hidden, Krystin A.; Malik, Azeem T.; Khan, Safdar N.; Phieffer, Laura; Ly, Thuan V.; Quatman, Carmen E.; Orthopaedic Surgery, School of Medicine
    Introduction: Despite an increasing number of elderly individuals undergoing surgical fixation for ankle fractures, few studies have investigated peri-operative outcomes and safety of surgery in an octogenarian and nonagenarian population (age >80 years). Materials and methods: The 2012-2017 American College of Surgeons database was queried for patients undergoing open reduction internal fixation for isolated uni-malleolar, bi-malleolar and tri-malleolar ankle fractures. The study cohort was divided into 3 comparison groups (age <65 years, 65-75 and >80). Multi-variate regression analyzes were used to compare the independent effect of varying age groups on 30-day post-operative outcomes while controlling for baseline clinical characteristics and co-morbidity burdens. Results: A total of 19,585 patients were included: 5.3% were >80 years, 18.1% were 65-79 years, and 76.6% were <65 years. When compared to the non-geriatric population, individuals >80 years were at a significantly Abstract: higher risk of 30-day wound complications (OR 1.84; p = 0.019), pulmonary complications (OR 3.88; p < 0.001), renal complications (OR 1.96; p = 0.015), septic complications (OR 3.72; p = 0.002), urinary tract infections (OR 2.24; p < 0.001), bleeding requiring transfusion (OR 1.90; p = 0.025), mortality (or 7.44; p < 0.001), readmissions (OR 1.65; p = 0.004) and non-home discharge (OR 13.91; p < 0.001). Discussion: Octogenarians undergoing ankle fracture fixation are a high-risk population in need of significant pre-operative surgical and medical optimization. With the majority of patients undergoing non-elective ORIF procedures, it is critical to anticipate potential complications and incorporate experienced geriatric providers early in the surgical management of these patients. Conclusions: Octogenarians and nonagenarians are fundamentally distinct and vulnerable age groups with a high risk of complications, readmissions, mortality and non-home discharges compared to other geriatric (65-79 years) and non-geriatric (<65 years) patients. Pre-operative counseling and risk-stratification are essential in this vulnerable patient population.

    Pubic root fractures are commonly misread as anterior column fractures by radiologists: Single-institution study from a level 1 trauma center
    (Elsevier, 2021-09-30) Vajapey, Sravya P.; Ly, Thuan V.; McKeon, John F.; Vajapey, Anuhya S.; Lynch, Daniel J.; Harrison, Ryan K.; Orthopaedic Surgery, School of Medicine
    Background: We sought to determine how frequently pubic root fracture is incorrectly identified as anterior column fracture by radiologists and describe differences in characteristics and outcomes between injury patterns. Methods: We identified 155 patients who sustained pelvic or acetabular fractures at a single, level 1 trauma academic institution. Pelvis computed tomography (CT) scans were evaluated to determine whether patients sustained an anterior column fracture or pubic root fracture. Demographic and clinical factors such as mortality, ambulatory status, type of treatment (nonoperative/surgery), and mechanism of energy were assessed. Results: There were a total of 83 patients in the anterior column group and 72 patients in the pubic root cohort. Eighty-five percent of pubic root fractures were read as anterior column fractures by radiologists. A total of 77.8% of pubic root fractures had posterior ring involvement. Patients with true anterior column acetabular fracture were more likely to need surgery (63.86% vs 41.70%, P = 0.01) and be discharged to skilled nursing or inpatient rehabilitation (59.04% vs 40.27%, P = 0.02) compared to patients with pubic root fracture. Conclusion: Pubic root fractures are frequently misread as anterior column fractures in radiology reports. Correctly diagnosing pubic root fractures and differentiating them from anterior column acetabular fractures can have significant impact on patients.
