Rotator Cuff Injuries

Introduction: Pathology of the rotator cuff is the cause of most common problems at the shoulder joint and accurate diagnosis is essential for appropriate management. High-resolution real-time ultrasonography and MRI are successful imaging modalities for both rotator cuff and non–rotator cuff disorders and have important implications in the management of rotator cuff pathologies. This study was conducted to Compare the results obtained after the evaluation of rotator cuff injuries of shoulder joint by high resolution Ultrasonography and Magnetic Resonance Imaging. Methods: 50 patients with suspected rotator cuff injuries of the shoulder joint were included in this study over a period of 2years. Patients had presented with various complaints like prolonged pain in the shoulder joint with stiffness, restriction and difficulty in movement of the shoulder joint, traumatic injuries and recurrent dislocations of the shoulder joints. Results: Mean age was 41.6years ( range 15-80 ).Maximum patients were between 41-50 years (24%). 29 were males and 21 were females. In our study diagnostic accuracy of ultrasound in rotator cuff tears was 57. 14% for full thickness tears and 58.33 for partial thickness tears. The diagnostic accuracy of ultrasound in detection of complete tear of the supraspinatus muscle was 57.14% while that of MRI was 100%. Conclusion: High resolution Ultrasound being a dynamic study can be used as the first-line investigation for rotator cuff tear. Full-thickness rotator cuff tears can be identified using ultrasound and MRI with comparable accuracy.

Abstract Background: The purpose of this study was to explore the distinction and relation among different types of chronic rotator cuff tears, in terms of some magnetic resonance imaging (MRI) parameters that reflected the greater tuberosity morphology.Methods: This study retrospectively assessed 160 patients diagnosedwith chronic rotator cuff tears (including bursal-side, articular-side and full-thickness rotator cuff tears) and 48 controls diagnosed without rotator cuff tears by MRI. The types of rotator cuff tear were confirmed by shoulder MRI and arthroscopy. Oblique coronal sections of MRI were used to measure the parameters including greater tuberosity abduction angle(GTAA), greater tuberosity width index (GTWI), and greater tuberosity height index(GTHI).Results: GTAA in patients with articular-side and full-thicknessrotator cuff tearswere smaller than those in patients with bursal-side rotator cuff tears and in controls.GTWI and GTHI were present in greater proportions in patients with articular-side and full-thickness rotator cuff tearsthan in patients with bursal-side rotator cuff tears and in controls.There was no significant difference between the articular-side and full-thickness cuff tears regarding GTAA, GTWI, or GTHI. The same was true between bursal-side rotator cuff tears and the controls.Conclusions: The greater tuberosity abduction angles are smaller, and greater tuberosity are more convex outward and upwardin patients with articular-side or full-thickness rotator cuff tears, than those in patients with bursal-side rotator cuff tears or in controls.

Background: Numerous studies have shown preoperative fatty infiltration of rotator cuff muscles to be strongly negatively correlated with the successful repair of massive rotator cuff tears (RCTs). Purpose: To assess the association between factors identified on preoperative magnetic resonance imaging (MRI), especially infraspinatus fatty infiltration, and the reparability of massive RCTs. Study Design: Case-control study; Level of evidence, 3. Methods: We analyzed a total of 105 patients with massive RCTs for whom MRI was performed ≤6 months before arthroscopic procedures. The mean age of the patients was 62.7 years (range, 46-83 years), and 46 were men. Among them, complete repair was possible in 50 patients (48%) and not possible in 55 patients (52%). The tangent sign, fatty infiltration of the rotator cuff, and Patte classification were evaluated as predictors of reparability. Using the receiver operating characteristic curve and the area under the curve (AUC), the prediction accuracy of each variable and combinations of variables were measured. Results: Reparability was associated with fatty infiltration of the supraspinatus ( P = .0045) and infraspinatus ( P < .001) muscles, the tangent sign ( P = .0033), and the Patte classification ( P < .001) but not with fatty infiltration of the subscapularis and teres minor ( P = .425 and .132, respectively). The cut-off values for supraspinatus and infraspinatus fatty infiltration were grade >3 and grade >2, respectively. The examination of single variables revealed that infraspinatus fatty infiltration showed the highest AUC value (0.812; sensitivity: 0.86; specificity: 0.76), while the tangent sign showed the lowest AUC value (0.626; sensitivity: 0.38; specificity: 0.87). Among 2-variable combinations, the combination of infraspinatus fatty infiltration and the Patte classification showed the highest AUC value (0.874; sensitivity: 0.54; specificity: 0.96). The combination of 4 variables, that is, infraspinatus and supraspinatus fatty infiltration, the tangent sign, and the Patte classification, had an AUC of 0.866 (sensitivity: 0.28; specificity: 0.98), which was lower than the highest AUC value (0.874; sensitivity: 0.54; specificity: 0.96) among the 2-variable combinations. Conclusion: The tangent sign or Patte classification alone was not a predictive indicator of the reparability of massive RCTs. Among single variables, infraspinatus fatty infiltration was the most effective in predicting reparability, while the combination of Goutallier classification <3 of the infraspinatus and Patte classification ≤2 of the rotator cuff muscles was the most predictive among the combinations of variables. This information may help predict the reparability of massive RCTs.
