Anterosuperior Glenoid Impingement Syndrome
نویسندگان
چکیده
Anterosuperior glenoid impingement is a well documented cause of shoulder pain. It occurs when there is deep tearing of the subscapularis, with fibers becoming embedded between the anterosuperior glenoid and humeral head. To our knowledge, this has not been described in radiologic literature and we present MRI findings depicting this entity.

Internal Impingement of the Shoulder: A Risk of False Positive Test Outcomes in External Impingement Tests?
BACKGROUND External impingement tests are considered as being particularly reliable for identifying subacromial and coracoid shoulder impingement mechanisms. The purpose of the present study was to evaluate if these tests are likely to provoke an internal shoulder impingement mechanism which, in cases of a pathologic condition, can lead to a positive test result. METHOD In 37 subjects, the me...
متن کاملInternal impingement syndromes.
Internal causes of impingement are secondary to rotator cuff and capsular dysfunction and are categorized by the location of the impingement and the underlying pathophysiological or mechanical cause of the impingement. These include posterosuperior impingement, anterosuperior impingement, anterior impingement, and entrapment of the long head of the biceps tendon. The objective of this article i...
متن کاملRe: shoulder impingement syndrome: relationships between clinical, functional, and radiologic findings.
OBJECTIVE Although there has been much research about imaging methods for shoulder impingement syndrome, the clinical information and upper limb level of disability have been generally ignored. The purpose of this study was to detect the relationships between clinical, functional, and radiologic variables in patients with shoulder impingement syndrome. DESIGN A cross-sectional, clinical, and ...
متن کاملGlenoid inclination: in vivo measures in rotator cuff tear patients and associations with superior glenohumeral joint translation.
Glenoid inclination has been associated with rotator cuff tears and superior humeral translation, but the relationship between glenoid inclination and superior humeral translation has not been assessed in vivo. This study compared glenoid inclination between repaired and contralateral shoulders in 21 unilateral rotator cuff repair patients. As a secondary analysis, we assessed the relationship ...
متن کاملIn vivo anatomy of the Neer and Hawkins sign positions for shoulder impingement.
The Neer and Hawkins impingement signs are commonly used to diagnose subacromial pathology, but the anatomy of these maneuvers has not been well elucidated in vivo. This 3-dimensional open magnetic resonance imaging study characterized shoulder anatomy and rotator cuff impingement in 8 normal volunteers placed in the Neer and Hawkins positions. Subacromial and intraarticular contact of the rota...
