Correlation between Results of Preoperative Impingement Test and Clinical Outcomes after Arthroscopic Rotator Cuff Repair

BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

The Possible Use Of The Acromial View As A Dynamic Test In Rotator Cuff Lesion / 대한정형외과학회잡지

OBJECTIVE: The purpose of this study is to reveal whether the acromial view (provisional name) can be used as a dynamic test in rotator cuff lesion. MATERIALS AND METHOD: One hundred and sixty-five patients who suffered from shoulder pain were reviewed. Average age was 53 years (male, 75; female, 90) . Criteria of positive finding were the spur or bony sclerosis at the contact area of the anterior acromion and greater tuberosity. The technique begins with placing the patient in a lateral decubitus position on the painful shoulder. After forward elevation of the upper arm up to 90 with internal rotation, the contralateral shoulder should be tilted forward about 10 to prevent overlapping with the painful shoulder. The tube tilts to 10 cephalad direction. The central X-ray is directed 1 cm medial to the lateral border of spine of the scapula. RESULTS: Thirty shoulders showed a positive finding. Average age was 55 years (male, 14; female, 16) . Sensitivity for the rotator cuff lesion was 31% and specificity was 95%. CONCLUSION: Although we need a more accurate method and a greater number of X-rays, the acromial view showed to be a valuable dynamic test for rotator cuff lesion with acromial spur.
