BACKGROUND Shoulder maneuvers and magnetic resonance imaging(MRI)are performed to diagnose supraspinatus tendon tears regardless of arthroscopy *** there are many studies on this subject,there is a lack of studies comparing the sensitivity(Se)and specificity(Sp)of shoulder maneuvers and MRI to arthroscopic findings(intact,partial,or full thickness supraspinatus tendon tear).AIM To compare the diagnostic values of shoulder maneuvers with MRI for supraspinatus tendon tears in patients undergoing shoulder *** A total of 199 consecutive patients from four orthopedic centers met the eligibility criteria of shoulder pain persisting for at least four *** were prospectively enrolled in this study from April 2017 to April *** clinical tests(full can,empty can,drop arm,Hawkins’,painful arc,Neer’s sign and resisted external rotation)and MRI were performed,and all were compared with surgical *** can,empty can and resisted external rotation tests were interpreted as positive in the case of pain and/or *** assessed the Se,Sp,accuracy,positive predictive value(PPV)and negative predictive value(NPV),positive and negative likelihood ratio and diagnostic odds ratio for overall,partial and fullthickness supraspinatus *** MRI had the highest Se for overall(0.97),partial(0.91)and full-thickness(0.99)tears;moreover,MRI had the highest NPV:0.90,0.88 and 0.98 for overall,partial and full-thickness tears,*** overall supraspinatus tears,the Se and PPV were:Painful arc(Se=0.85/PPV=0.91),empty can(pain)(Se=0.80/PPV=0.89),full can(pain)(Se=0.78/PPV=0.90),resisted external rotation(pain)(Se=0.48/PPV=0.87),drop arm(Se=0.19/PPV=0.97),Neer’s sign(Se=0.78/PPV=0.93)and Hawkins’(Se=0.80/PPV=0.88).MRI had the highest PPV(0.99).The Hawkin’s test had the highest false positive rate in patients with intact tendons(0.36).The Sp of the empty can and full can(both tests positive for pain and weakness),drop arm and MRI were:0.93,

AIM To compare the functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair. METHODS Eighty-seven patients with rotator cuff tears following arthroscopic treatment were divided into traumatic and non-traumatic tear groups. Postoperative muscle strength and outcomes using the modified University of California, Los Angeles score were evaluated. Sex, age, affected limb and dominant limb were correlated between groups. Muscle strength of the repaired and unaffected shoulders was compared. Rotator cuff injury size was measured. RESULTS Of the 87 patients who underwent rotator cuff repairs, 35 had traumatic tears and 52 had non-traumatic tears. In patients with non-traumatic tears, the average age was 59 years, 74.5% were female, 96.1% were righthand dominant and 92.3% had their dominant shoulder affected. Patients with traumatic tears were 59.5 yearsold on average, 51.4% were female, 91.4% were righthand dominant and 88.5% had their dominant shoulder affected. No difference existed in the mean modified University of California, Los Angeles score between patients with traumatic tears(33.7) compared with those with non-traumatic tears(32.8). No strength differences were observed between groups: The strength difference between the non-affected and affected sides was 1.21 kg in the non-traumatic group and 1.39 kg in the traumatic group(P = 0.576), while the strength ratio between the non-affected/affected sides was 0.805 in the nontraumatic group and 0.729 in the traumatic group(P = 0.224). CONCLUSION The functional results of traumatic rotator cuff repairs are similar to non-traumatic tears. Both outcomes are satisfactory.
