Excursion of the rotator cuff under the acromion. Patterns of subacromial contact.
Nine fresh-frozen, human cadaveric shoulders were elevated in the scapular plane in two different humeral rotations by applying forces along action lines of rotator cuff and deltoid muscles. Stereophotogrammetry determined possible regions of subacromial contact using a proximity criterion; radiographs measured acromiohumeral interval and position of greater tuberosity. Contact starts at the an...
متن کاملRotator cuff impingement due to enchondroma of the acromion.
We report the case of a patient with a long standing clinical history of subacromial impingement, in which plain radiographs and CT-scan revealed a well-circumscribed lucent lesion expanding the undersurface of the acromion. MRI showed the subacromial fat to be completely obliterated and the infraspinatus tendon deformed due to compression by a mass localised at the acromion. The acromial lesio...
متن کاملRadiographic Study on the Acromion Index and Its Relationship with Rotator Cuff Tears.
OBJECTIVE The purpose of this study was to evaluate the relationship between the lateral projection of the acromion and rotator cuff tears (RCTs) in the Brazilian population. METHODS The lateral projection of the acromion was measured using anteroposterior radiographs of the shoulders, carried out with the glenoid cavity in absolute profile and the humeral head in the neutral position or with...
متن کاملDoes a positive neer impingement sign reflect rotator cuff contact with the acromion?
BACKGROUND One possible cause of shoulder pain is rotator cuff contact with the superior glenoid (cuff-glenoid contact) with the arm in flexion, as occurs during a Neer impingement sign. It has been assumed that the pain with a Neer impingement sign on physical examination of the shoulder was secondary to the rotator cuff making contact with the anterior and lateral acromion. QUESTIONS/PURPOS...
متن کاملThe Rotator Cuff
The annual prevalence and incidence of people consulting for a shoulder condition is about 2.4% in the UK [1]. Shoulder pain in the population is also a longterm disabling symptom with about 50% complaining of symptoms 3 years after onset[2]. Common conditions that can result in chronic shoulder pain include rotator cuff disorders, frozen shoulder, shoulder instability, and shoulder arthritis. ...
