Objectives: It is not clear if using patients with bilateral symptoms would impact the level of disability reported in orthopaedic research. The purposes of this study were to (1) examine the prevalence of bilateral shoulder symptoms (significant pain, stiffness or weakness affecting function) in patients with rotator cuff impingement syndrome, rotator cuff tear and osteoarthritis of the glenohumeral joint, (2) explore risk factors associated with bilateral shoulder symptoms, and (3) examine the impact of symptom bilaterality and hand dominance on pre- and post-operative patient-oriented disability outcomes. Methods: This study involved secondary analysis of prospectively collected data of patients who had undergone shoulder surgery and had returned for their 1-year follow-up. Two outcome measures were collected prior to surgery and at 1-year following surgery: the American Shoulder and Elbow Surgeons and the Constant–Murley Score. Results: Data of 772 patients, 376 (49%) females, 396 males (51%); 288 (impingement syndrome), 332 (rotator cuff tear), and 152 (osteoarthritis) were included in the analysis. There was a statistically significant difference in the prevalence of bilateral symptoms being 44%, 28%, and 22% in the osteoarthritis, impingement syndrome, and rotator cuff tear groups, respectively (p < 0.0001). The prevalence of dominant side involvement was 71%, 67%, and 53% in the rotator cuff tear, impingement syndrome, and osteoarthritis groups (p < 0.0001). Older age and female sex were risk factors for development of bilateral symptoms only in patients with rotator cuff tear. Neither symptom bilaterality nor dominant arm involvement had a negative impact on patient-oriented disability outcome measures prior to or after surgery (p > 0.05). Conclusion: This study shows that patients with osteoarthritis of the glenohumeral joint have the highest prevalence of bilateral shoulder complaints. The older age and the female sex increased the risk of having bilateral symptoms in patients with rotator cuff tear. Having bilateral shoulder symptoms or dominant side involvement was not associated with higher level of disability prior or after surgery.

Lipoma arborescens is a rare synovial lesion characterized by villous proliferation of the synovial membrane and replacement of subsynovial tissue with mature fat cells. The knee joint is the most frequently affected site, particularly in the suprapatellar pouch. However, there have been few reports regarding shoulder involvement, including the glenohumeral joint and subacromial subdeltoid bursa, associated with rotator cuff tear. This article reviews the case of a 67-year-old man who presented with lipoma arborescens of the left shoulder, associated with a rotator cuff tear. Sonography revealed a fluid collection with thickening of the synovial membrane with hyperechoic villous proliferation, located in the subdeltoid bursa. An arthroscopic synovectomy and rotator cuff repair were performed. Arthroscopic findings included yellow frond-like synovial proliferation of the synovium. Postoperatively, the patient was asymptomatic, and the lesion did not recur. Although magnetic resonance imaging is the first-line imaging modality for diagnosis of this lesion, sonography may be used initially for evaluation of chronic joint swelling. In addition, it can be useful for detection of recurrence after synovectomy. This case illustrates the typical sonographic features of lipoma arborescens.

Abstract The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

Objective. To document the incidence of asymptomatic rotator cuff tears in patients with a confirmed symptomatic tear in the opposite shoulder, and to identify ultrasound findings that may distinguish symptomatic from asymptomatic tears. Design. When patients are referred for an ultrasound examination for the confirmation of symptomatic rotator cuff tear the opposite shoulder is often used for comparison. However, patients often have a similar tear on the asymptomatic side. Fifty patients with a confirmed symptomatic rotator cuff tear and an asymptomatic shoulder on the opposite side were chosen for inclusion. The patients were examined using a Siemens Sonoline Elegra 7.5 MHz linear multi-frequency probe. The appearance of the rotator cuff, long head of the biceps and the subacromial-subdeltoid bursa (SASD bursa) were documented. The antero-posterior (AP) dimension of the supraspinatus muscle and fat between the trapezius and supraspinatus muscles were measured, which indicated if a tear was acute or chronic. The width and length of the rotator cuff tear were measured. Setting. Division of Sports Medicine, University of Pretoria. Results. Fifty-four per cent of the asymptomatic shoulders had tears. We found that the symptomatic tears were larger, appeared more chronic and had an associated biceps tendinopathy and glenohumeral joint effusion. Conclusion. As other authors have found, the high incidence of asymptomatic tears indicates that rotator cuff tears can be regarded as a natural correlate of aging and that bilateral tears are common. Initial treatment should be conservative, but larger tears may benefit from early surgery before becoming chronic and causing glenohumeral dysfunction.

Rotator cuff tears are common injuries seen by orthopaedic surgeons. Management may vary depending on patient factors, size and location of tear, and severity of symptoms. Treatment for symptomatic rotator cuff tear often includes subacromial decompression, debridement, and/or repair. The objective of this study was to determine the change in glenohumeral joint (GHJ) forces after repair of pathologic supraspinatus tears.
