Background Many patients with rotator cuff tears suffer from nocturnal shoulder pain, resulting in sleep disturbance. Purpose To determine whether rotator cuff tear size correlated with sleep disturbance in patients with full-thickness rotator cuff tears. Study Design Cross-sectional study; Level of evidence, 3. Methods Patients with a diagnosis of unilateral full-thickness rotator cuff t...

Anatomic factors, such as a hooked acromion, have been associated with rotator cuff disorders. Orientation of the glenoid relative to the scapula has been implicated in shoulder instability, but it has not been linked to rotator cuff disorders. The purpose of the current study was to test the hypothesis that superior inclination of the glenoid is associated with full-thickness rotator cuff tear...

The time-course covered by the original definition of scapulo-humeral periarthritis suggested by Duplay through the more recent term of subacromial impingement syndrome coined by Neer, follows the identification of the pathogenetic mechanisms leading to chronic subacromial impingement and degenerative tears of the rotator cuff. The Authors recall the functional-anatomic development evolution of...

We have studied cellular and vascular changes in different stages of full thickness tears of the rotator cuff. We examined biopsies from the supraspinatus tendon in 40 patients with chronic rotator cuff tears who were undergoing surgery and compared them with biopsies from four uninjured subscapularis tendons. Morphological and immunocytochemical methods using monoclonal antibodies directed aga...

OBJECTIVE To assess the diagnostic performance of MR arthrography in the diagnosis of the various types of partial-thickness rotator cuff tears by comparing the MR imaging findings with the arthroscopic findings. MATERIALS AND METHODS The series of MR arthrography studies included 202 patients consisting of 100 patients with partial-thickness rotator cuff tears proved by arthroscopy and a con...

PURPOSE The aim of the present study was to investigate whether coracoacromial arch angle is a predisposing factor for rotator cuff tears. METHODS Shoulder magnetic resonance imaging (MRI) examinations of 40 patients having shoulder arthroscopy due to rotator cuff tears and 28 patients with normal MRI findings were evaluated retrospectively. Acromio-humeral distance, coraco-humeral distance, ...

Rotator cuff tears in young overhead sports athletes are rare. The pathomechanism causing rotator cuff tears in young overhead athletes is different from that in aged patients. The purpose of this study was to investigate rotator cuff tear characteristics in young overhead sports athletes to reveal the pathomechanism causing these injuries. This study included 25 overhead sports athletes less t...

We prospectively evaluated the diagnostic value of sonography and magnetic resonance imaging (MRI) in 24 shoulders in 23 patients with suspected rotator cuff tears using arthrography as gold standard. Sonography demonstrated 14 of 15, MRI 10 of 15 rotator cuff tears, respectively. Sonography diagnosed seven of nine intact rotator cuffs correctly, MRI eight of nine. In a retrospective study we r...

Tendon tears of the rotator cuff show a high prevalence in today's population. Patients suffer from permanent pain and disability, and surgical reconstruction may be the only possibility for abatement. The complex process of tendon-bone healing leads to mechanically inferior scar-tissue, which often results in retears or non-healing. In the current literature, factors such as patients age, sex ...

introduction professional sports injuries are usually all dealt with at one single operation to return the player to the sport after appropriate rehabilitation. we questioned the assumption that rotator cuff tears must be repaired concurrently with instability syndromes, and aimed to allow a professional rugby league player to achieve career goals by not correcting all pathology at one surgery....
