bookPart Diagnóstico por Imagem nas Doenças Ósseas(2016) RODRIGUES, Marcelo Bordalo; VITULE, Luiz Fernando; PEREZ, Mariana Ortega; PEREIRA, Rosa Maria Rodrigues- Serial structural MRI evaluation of arthroscopy rotator cuff repair: does Sugaya's classification correlate with the postoperative clinical outcomes?(2016) MALAVOLTA, Eduardo A.; ASSUNCAO, Jorge Henrique; RAMOS, Frederico F.; FERREIRA, Thiago C.; GRACITELLI, Mauro E. C.; BORDALO-RODRIGUES, Marcelo; FERREIRA NETO, Arnaldo A.Sugaya's classification is the most commonly used for postoperative evaluation of rotator cuff repairs. However, the correlation between this classification and clinical outcomes after supraspinatus tendon repair were not performed with serial MRI examinations in standardized time intervals. This prospective case series involved 54 patients undergoing repair of the supraspinatus tendon tear. Magnetic resonance imaging (MRI, 1.5 T) was used to determine the Sugaya's classifications at 3, 6, and 12 months, and these data were correlated with the visual analog scale for pain (VAS), Constant and University of California at Los Angeles (UCLA) assessments. Patients with types I, II, and a parts per thousand yenIII of Sugaya's classification experienced pain of 1.27 +/- 1.95, 1.00 +/- 1.40, and 3.43 +/- 3.36, respectively (p = 0.010), according to the VAS. The Constant and UCLA scales did not differ significantly. Type II predominated, though their percentage decreased over time (from 77.8 to 66.7 %), whereas type I became more frequent (from 1.9 to 20.4 %). The pain was more intense in patients classified as types III, IV, or V of Sugaya's classification. The postoperative appearance of the supraspinatus tendon was not correlated with the Constant and UCLA scales. The occurrence of type II, the most prevalent, decreased over time, whereas the occurrence of type I increased; these differences were not significant. Level de evidence: prospective cohort evaluation-level III.
- Accuracy of preoperative MRI in the diagnosis of subscapularis tears(2016) MALAVOLTA, Eduardo A.; ASSUNCAO, Jorge H.; GUGLIELMETTI, Cesar L. B.; SOUZA, Felipe F. de; GRACITELLI, Mauro E. C.; BORDALO-RODRIGUES, Marcelo; FERREIRA NETO, Arnaldo A.The subscapularis has received little attention in the orthopedic literature, although such lesions are evident in up to 40 % of arthroscopies. An accurate diagnosis is important in clinical practice, as it affects both patient prognosis and surgical planning. The aim of this study was to evaluate the accuracy of preoperative MRI for the identification of subscapularis tears. Our secondary aim involved the identification of factors that may be predictive for the presence of subscapularis tears. This retrospective case series included patients undergoing shoulder arthroscopy due to rotator cuff injury. MRI was performed using a 1.5 T unit, and the results were assessed by a musculoskeletal radiologist. The findings were compared to those of arthroscopic inspection. A total of 93 shoulders were analyzed. The overall accuracy was 82 %, with values of 79 % for partial tears and 89 % for full-thickness tears. Tears requiring repair demonstrated an accuracy of 88 %. Infraspinatus tears, fatty degeneration of the subscapularis, biceps instability and age were identified as predictive factors for the presence of injury. MRI of the shoulder demonstrated an accuracy of 82 % for the diagnosis of subscapularis tears. The accuracy values for partial and full-thickness tears were 79 and 89 %, respectively. III, development of diagnostic criteria with universally applied reference-nonconsecutive patients.
