Comparative Study between Multi-slice Computed Tomographic Arthrography and Arthroscopy in the Evaluation of Rotator Cuff Tears / Estudo comparativo entre artrotomografia computadorizada multi-slice e artroscopia na avaliação das lesões do manguito rotador

Abstract Objective To compare the imaging findings of anatomical alterations using multi-slice computed tomographic arthrography in the evaluation of rotator cuff tears in the shoulder, correlating them with the arthroscopy (the gold standard diagnostic test) findings. Materials and Methods A longitudinal, prospective, comparative study of diagnostic accuracy performed in the period between June 2016 and June 2017 in patients of both sexes, aged between 40 and 70 years, with shoulder rotator cuff tendon tears and therapeutic need to undergo shoulder arthroscopy. Patients with contraindication to magnetic resonance imaging were included. After multi-slice computed tomographic arthrography, all patients underwent arthroscopy. Results To obtain the results, the following parameters were determined: sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and Kappa coefficient, and contrast between the imaging method and arthroscopy. Conclusion In the impossibility of performing magnetic resonance imaging (the gold standard imaging technique), multi-slice computed tomographic arthrography is an imaging examination capable of evaluating/diagnosing rotator cuff tears.

Resumo Objetivo Comparar os achados por imagem das alterações anatômicas da artrotomografia computadorizada multi-slice na avaliação das lesões do manguito rotador do ombro e correlacioná-los com os achados da artroscopia (exame diagnóstico padrão-ouro). Materiais e Métodos Estudo longitudinal, prospectivo, comparativo de acurácia diagnóstica, feito de junho de 2016 a junho de 2017, em pacientes de ambos os sexos, com idades entre 40 e 70 anos, com lesão dos tendões do manguito rotador do ombro, e que tinham necessidade terapêutica de fazer artroscopia do ombro. Foram incluídos pacientes com contraindicação à realização de ressonância magnética. Após a artrotomografia computadorizada multi-slice, todos os pacientes foram submetidos a artroscopia. Resultados Para a obtenção dos resultados, os seguintes parâmetros foram considerados: sensibilidade, especificidade, acurácia, valor preditivo positivo, valor preditivo negativo, coeficiente Kappa, e contraposição do método de imagem com a artroscopia. Conclusão Na impossibilidade da realização da ressonância magnética (exame de imagem padrão-ouro), a artrotomografia computadorizada multi-slice se mostra um exame de imagem capaz de avaliar/diagnosticar as lesões do manguito rotador.

ARTHROSCOPIC TREATMENT OF ELBOW STIFFNESS.

UNLABELLED: To present the arthroscopic surgical technique and the evaluation of the results from this technique for treating elbow stiffness. METHODS: Between April 2007 and January 2010, ten elbows of ten patients with elbow stiffness underwent arthroscopic treatment to release the range of motion. The minimum follow-up was 11 months, with an average of 27 months. All the patients were male and their average age was 32.8 years (ranging from 22 to 48 years). After the arthroscopic treatment, they were followed up weekly in the first month and every three months thereafter. The clinical evaluation was made using the criteria of the University of California at Los Angeles (UCLA). RESULTS: All the patients were satisfied with the results from the arthroscopic treatment. The average UCLA score was 33.8 points. CONCLUSION: Arthroscopic treatment for elbow stiffness is a minimally invasive surgical technique that was shown to be efficient for treating this complication.

ARTHROSCOPIC TREATMENT OF ACROMIOCLAVICULAR JOINT DISLOCATION BY TIGHT ROPE TECHNIQUE (ARTHREX(®)).

UNLABELLED: Presenting the arthroscopic treatment by Tight Rope - Arthrex(®) system for acute acromioclavicular dislocation and to evaluate results obtained with this procedure. METHODS: Between August 2006 and May 2007, 10 shoulders of 10 patients with acute acromioclavicular dislocation were submitted to arthroscopic repair using the Tight Rope - Arthrex(®) system. Minimum follow-up was 12 months, with a mean of 15 months. Age ranged from 26 to 42, mean 34 years. All patients were male. Radiology evaluation was made by trauma series x-ray. The patients were assisted in the first month weekly and after three months after the procedure. Clinical evaluation was based on the University of California at Los Angeles (UCLA) criteria. RESULTS: All patients were satisfied after the arthroscopic procedure and the mean UCLA score was 32,5. CONCLUSION: The arthroscopic treatment by Tight Rope - Arthrex(®) system for acute acromioclavicular dislocation showed to be an efficient technique.
