Femoral shaft fracture: reproducibility of AO-ASIF and Winquist classifications

OBJECTIVE: To evaluate inter-observer reproducibility of AO / ASIF and Winquist-Hansen classifications for shaft fractures of the femur in adults. METHODS: 50 anterior-posterior and profilelateral radiographs were randomly selected, of adult patients awith diaphyseal fracture of the femur. The radiographs were analyzed by 5 observers-a member of the Brazilian Society of Orthopedic Trauma, a radiologist and 3 residents. To assess the concordance between these classifications, we used the statistical index Kappa (K). RESULTS: In all analyses, we observed a statistically significant correlation coefficient between observers (p <0.05) and according to the criteria of Landis and Koch, they were ranked them as good (values of 0.61 to 0.80) or very good (values above 0.80). CONCLUSION: The AO rating and Winquist present a high rate of concordance between observers for shaft fractures of the femur in adults.OBJETIVO: Avaliar a reprodutibilidade interobservadores das classificações AO/ASIF e de Winquist para as fraturas diafisárias do fêmur no adulto. MÉTODOS: foram selecionadas aleatoriamente 50 radiografias de pacientes adultos portadores de fratura diafisária do fêmur nas incidências em antero-posterior e perfil. As radiografias foram analisadas por 5 observadores, sendo um membro da Sociedade Brasileira de Trauma Ortopédico, um radiologista, um residente do terceiro ano de Ortopedia e Traumatologia, um do segundo e um do primeiro. Para avaliar a concordância interobservadores destas classificações, foi utilizado o índice estatístico Kappa (K). RESULTADOS: Em todas as análises, observou-se um coeficiente de concordância entre observadores estatisticamente significativo (valor p < 0,05) e classificado como bom (valores de 0,61 a 0,80) ou muito bom (valores acima de 0,80), segundo os critérios de Landis e Koch. CONCLUSÃO: As classificações AO e Winquist apresentam alto índice de concordância interobservadores para as fraturas diafisárias do fêmur no adulto.Universidade Federal de Minas Gerais Hospitais Felício Rocho e da Baleia Departamento do Aparelho LocomotorUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaHospital Felício Rocho Serviço de Ortopedia e TraumatologiaUniversidade Federal de Minas Gerais Departamento do Aparelho LocomotorUNIFESP, EPMSciEL

PATIENTS WITH SPINAL METASTASIS SUBMITTED TO NEUROLOGICAL DECOMPRESSION AND STABILIZATION

ABSTRACT Objective: To analyze retrospectively the surgical outcomes of a group of patients with bone metastases and multiple myeloma in the spine, which underwent neurological decompression and arthrodesis using pedicle screws, by isolated posterior approach, to check whether the operated patients present clinical improvement regarding the pain and neurological deficit compared to the preoperative period. Methods: This is a retrospective, cross-sectional study of case series, that analyzed data from medical records of patients with bone metastases in the spine who underwent surgical treatment between January 2007 and February 2011. Results: Of the 42 patients in the sample, according to the Kolmogorov-Smirnov test (p=0.000) there was improvement in pain with respect to the preoperative, with 33 patients (78.6%) reporting improvement and only 9 (21.4%) maintaining the initial pain complaints. Of the 25 patients available for evaluation of neurological improvement (≠ Frankel E) 9 patients (36%) had some kind of improvement postoperatively, and no operated patient presented neurological worsening, indicating statistical significance according to the Kolmogorov-Smirnov test (p = 0.000). It was also observed statistical correlation (p=0.042) between Frankel functional score postoperatively and pain relief, using the chi-square test. Conclusions: Surgical treatment for patients with spinal metastasis through arthrodesis with pedicle instrumentation and decompression may have significant clinical benefits, especially as regards the improvement in pain symptoms and improved neurological function

CLINICAL-RADIOGRAPHIC CORRELATION OF DEGENERATIVE CHANGES OF THE SPINE - SYSTEMATIC REVIEW

ABSTRACT Systematic review of the literature on the evaluation of images of degenerative changes of the spine and its clinical correlation. A systematic literature review was conducted, and the results evaluated for the presence of clinical correlation, as well as the type of imaging method used. The search terms were "Intervertebral Disc Degeneration", "Intervertebral disc", "Classification", "Anulus fibrosus", "Nucleus pulposus", "Lumbar spine", "Degenerative disc disease", "Degeneration", "Zygapophyseal Joint". We also assessed whether there were inter- and intraobserver agreement in the selected works and possible guidelines regarding the treatment and prognosis of patients. Of the 91 reviewed abstracts, 31 articles were selected that met the inclusion criteria. Six articles were related to the cervical spine, 13 to the lumbar spine and 12 were about changes not related specifically to a single segment of the spine. Articles that determined limiting values considered normal were also included, since variations were considered signs of degeneration or pathology. It was not possible to establish the relationship between the changes identified in imaging and the clinical history of patients, either define treatment and prognosis guidelines
