- ItemAn assessment of the Chilean National Examination of Orthopaedic Surgery(2016) Urrutia Escobar, Julio Octavio; Orrego, Mario; Wright Navarrete, Ana Cecilia; Amenábar Velasco, Diego José.Abstract Background The Chilean National Examination of Orthopaedic Surgery (EMNOT) has been administered since 2009. It was developed to determine whether individual residents are meeting minimal knowledge standards at the end of their training programs. Methods We performed a retrospective evaluation of the EMNOT for all years it has been administered (2009–2015). The test was analyzed for content, taxonomy of questions asked (1: direct recall; 2: diagnosis; 3: evaluation/decision-making), residents’ performance, difficulty index and discrimination index. Results During the years of EMNOT administration, the most frequently tested areas have been pediatric orthopaedics (22.9 %), spine (13.8 %), general orthopaedics (13.8 %) and musculoskeletal trauma (9.9 %). A significant increase in questions with images was observed, as well as a significant decrease in the percentage of Type 1 and an increase in Type 3 questions. The Difficulty Index showed a medium level of difficulty for all years the examination has been administered. The Discrimination Index showed good discrimination in 2009, fair discrimination from 2010 through 2012, and excellent discrimination from 2013 through 2015. Conclusion The EMNOT has evolved over several years to include better quality questions, better discrimination, and a more representative distribution of questions covering the different orthopaedic sub-specialties. This examination represents an effective instrument for quality assurance of orthopaedic residency programs in Chile.

- ItemDo Patients Older Than 60 Years With Inflammatory Bowel Disease Have More Vertebral Fractures Than Age-matched Controls? A Study Using Abdominal and Pelvic CT Scans With Sagittal Reformatting as Screening Tool.(2020) Besa Vial, Pablo José; Meissner, Arturo; Ledermann, Gerardo; Pérez Valenzuela, Javier; Vergara López, María; Álvarez Lobos, Manuel; Urrutia Escobar, Julio OctavioIntroduction: Inflammatory bowel disease (IBD) has been associated with metabolic bone disease and increased fractures. This association is directly influenced by the disease and indirectly influenced by treatment. Therefore, patients with IBD could develop an elevated risk of osteoporotic fractures, particularly vertebral compression fractures (VCFs); however, symptomatic VCFs have not been shown to be more common in these patients. Our study evaluated the prevalence of VCF, independent of the presence of spinal symptoms, in IBD patients. Methods: We assessed IBD patients previously enrolled in a prospective cohort. All patients from that cohort who underwent computed tomography (CT) scans for nonspinal conditions were evaluated to detect the presence of VCFs. VCFs were classified using the Genant scheme. We evaluated whether patients with or without VCF differed in demographic data, type of IBD, treatment received and time from diagnosis. We used logistic regression to assess the independent effect of each variable. Results: In total, 6.5% of these patients had at least one VCF. Most fractures were Genant I (77%) and mostly at the thoracolumbar junction (T11 to L2, 65%). Bivariate and logistic regression analyses showed that age was the only variable independently associated with VCF (OR 1.12, 1.05 to 1.19). Conclusion: VCFs are not unusual in OBD patients. Radiologists and clinicians should specifically look for the presence of VCFs in patients with IBD, particularly the elderly, by using abdominal and pelvic CT scans.
- ItemDo thoraco-lumbar spinal injuries classification systems exhibit lower inter- and intra-observer agreement than other fractures classifications?: A comparison using fractures of the trochanteric area of the proximal femur as contrast model(2016) Urrutia Escobar, Julio Octavio; Zamora, T.; Klaber Rosenberg, Ianiv; Carmona, M.; Palma, J.; Campos, M.; Yurac, R.Introduction It has been postulated that the complex patterns of spinal injuries have prevented adequate agreement using thoraco-lumbar spinal injuries (TLSI) classifications; however, limb fracture classifications have also shown variable agreements. This study compared agreement using two TLSI classifications with agreement using two classifications of fractures of the trochanteric area of the proximal femur (FTAPF). Material and methods Six evaluators classified the radiographs and computed tomography scans of 70 patients with acute TLSI using the Denis and the new AO Spine thoraco-lumbar injury classifications. Additionally, six evaluators classified the radiographs of 70 patients with FTAPF using the Tronzo and the AO schemes. Six weeks later, all cases were presented in a random sequence for repeat assessment. The Kappa coefficient (κ) was used to determine agreement. Results Inter-observer agreement: For TLSI, using the AOSpine classification, the mean κ was 0.62 (0.57–0.66) considering fracture types, and 0.55 (0.52–0.57) considering sub-types; using the Denis classification, κ was 0.62 (0.59–0.65). For FTAPF, with the AO scheme, the mean κ was 0.58 (0.54–0.63) considering fracture types and 0.31 (0.28–0.33) considering sub-types; for the Tronzo classification, κ was 0.54 (0.50–0.57). Intra-observer agreement: For TLSI, using the AOSpine scheme, the mean κ was 0.77 (0.72–0.83) considering fracture types, and 0.71 (0.67–0.76) considering sub-types; for the Denis classification, κ was 0.76 (0.71–0.81). For FTAPF, with the AO scheme, the mean κ was 0.75 (0.69–0.81) considering fracture types and 0.45 (0.39–0.51) considering sub-types; for the Tronzo classification, κ was 0.64 (0.58–0.70). Conclusion Using the main types of AO classifications, inter- and intra-observer agreement of TLSI were comparable to agreement evaluating FTAPF; including sub-types, inter- and intra-observer agreement evaluating TLSI were significantly better than assessing FTAPF. Inter- and intra-observer agreements using the Denis classification were also significantly better than agreement using the Tronzo scheme.
