Partial rotator cuff tears are the most common pathology of the shoulder joint. Diagnostic of such conditions is a challenging problem for trauma surgeon.Purpose of the study is to analyze the diagnostic significance of manual tests and the standard MRI of the shoulder joint.Materials and Methods. The study is a retrospective analysis of disease history data of 25 patients (15 males, 10 females) treated at the authors’ hospital during the period from 2014 to 2017. Examination was performed according to a standard protocol: assessment of shoulder range of motion, palpation, manual examination, including “full/empty can” test, a painful arc symptom and the Hawkins – Kennedy test. All patients underwent MRI of the shoulder joint. The mean age of patients was 50.8 years. Shoulder joint arthroscopic inspection was considered the gold standard for diagnostics.Results. After data analysis, the following results were obtained: sensitivity of the “full can” test was 68%, the accuracy was 68%; “empty can” test sensitivity and accuracy were 76%, respectively. MRI sensitivity for diagnostics of supraspinatus tendon ruptures was 84% with the accuracy of 84%. The combination of the Hawkins – Kennedy test with the symptom of painful arch demonstrated accuracy and sensitivity of 64%. The study evaluated the effectiveness of MRI for diagnostic of the rupture type: sensitivity for injury from the joint surface — 80%, from the subacromial space — 70%; specificity for ruptures from the articular surface — 90% and from the subacromial space — 93%. The accuracy was 84% for both types of ruptures.Conclusions. Combined application of manual tests and MRI of the shoulder joint allows to diagnose partial rotator cuff tears in the majority of cases.
Background. The shoulder MRI is one of the main methods for the rotator cuff injuries diagnostics and determination of the further treatment tactics. The agreement in the MRI data interpretation among specialists regarding different types of shoulder ruptures is an integral part of diagnostic test validity evaluation. The purpose of this study was to assess the agreement in the MRI data interpretation in the patients with shoulder rotator cuff pathology among trauma surgeons, as well as between trauma surgeons and a radiologist. Materials and Methods. The study was a retrospective analysis of the MRI data and surgical reports regarding 57 patients with various shoulder pathologies undergone the shoulder MRI and arthroscopic shoulder revisions in the period from 2017 to 2019. There were 38 (67%) men and 19 (33%) women among the patients. The average age of the patients was 52.7±13.6 years. The sensitivity and specificity, as well as the shoulder MRI inter-rater reliability were assessed in the course of the study. Results. The rotator cuff pathology was revealed in 52 patients: supraspinatus tendon injury in 98% of cases, supraspinatus and infraspinatus tendon — in 26%, isolated subscapularis tendon injury — in 2%, supraspinatus and subscapularis tendon — in 39%. The maximal concordance in the MRI data interpretation was achieved in the patients with full-thickness supraspinatus tendon rupture, as well as with the supraspinatus tendon calcifications. However, significant disagreement was found between orthopedists with different work experience in determination of the presence and type of infraspinatus and subscapularis tendons pathology and supraspinatus tendon incomplete ruptures and tendinitis. Conclusion. The high agreement in the MRI data interpretation in determining the pathology of the shoulder rotator cuff among trauma surgeons, as well as between trauma surgeons and radiologists, was observed only regarding the supraspinatus tendon, calcifying tendonitis and full-thickness injury. The diagnosis of tendinitis and incomplete tendon rupture remains difficult. Their interpretation results vary greatly. It is also worth noting the heterogeneity of the results of diagnostics of the infraspinatus and subscapularis tendon pathology.
Реферат American Shoulder and Elbow Surgeons standardized assessment form (ASES)-одна из наиболее часто используемых специализированных шкал для оценки состояния плечевого сустава. Однако до настоящего времени шкала не валидирована на русском языке. Целью работы является кросс-культурная адаптация и валидация шкалы оценки функции плечевого сустава ASES. Материал и методы. В исследование были включены 93 пациента с различной патологией плечевого сустава, медиана возраста-49 лет, в том числе 39 мужчин и 54 женщины. Первым этапом была проведена языковая и культурная адаптация опросника ASES, в результате чего была получена его максимально приближенная версия. Далее была проведена оценка психометрических свойств опросника (надежность, валидность). Были изучены эффекты максимальных и минимальных значений (floor and ceiling effects), оценен коэффициент внутреннего постоянства альфа Кронбаха и воспроизводимости. Для оценки воспроизводимости использовали метод «тест-ретест», для которого было отобрано 20 пациентов. Эти пациенты заполняли опросник ASES при первичном обращении к травматологу-ортопеду и повторно через 7 дней, полученные данные оценивали с помощью коэффициента внутриклассовой корреляции (ICC-intra-class correlation coefficient). В рамках работы была проведена оценка валидности полученной шкалы, в том числе для оценки критериальной валидности оценивали взаимосвязь результатов исследуемого опросника с результатами валидизированного в России опросника DASH. Результаты. В рамках исследования получена оценочная шкала, полностью соответствующая оригинальной версии с незначительными лингвистическими и культурными особенностями. Медиана значений результатов по шкале ASES-68,7 [32,6; 93,8], максимальных и минимальных баллов по шкале получено не было. Русскоязычная версия опросника обладает хорошими психометрическими свойствами. Внутренняя согласованность-альфа Кронбаха 0,72. Общий внутриклассовый коэффициент корреляции анкеты ASES (ICC) составил 0,95 (р<0,05). Статистически значимых различий между общей группой исследуемых пациентов и группой «тест-ретест» по полу, возрасту и виду патологии плечевого сустава выявлено не было. Коэффициент корреляции между шкалами ASES и DASH составил 0,9; индекс GRI-3,05. Заключение. Адаптированная русская версия анкеты ASES обладает хорошими психометрическими свойствами и может быть рекомендована к применению для оценки функционального состояния пациентов с патологией плечевого сустава и динамики изменений в процессе лечения. Ключевые слова: патология плечевого сустава, шкала оценки, ASES, DASH.
