Bladder cancer is the fourth most common malignancy among men in the Western world. Bone metastasis occurs in 27 % of the cases. Usually, the location is the spine. The present report describes the first case of a proven distant bone metastasis to the acromion from a urinary bladder carcinoma in a patient with shoulder pain.

Introduction Subacromial impingement syndrome (SIS) is a general term used to describe a variety of conditions that may act independently or in combination, and manifest as anterior or anterior-lateralsuperior shoulder pain. SIS occurs as a result of pathology of one or more of the structures located within the subacromial space. The pain is associated with a loss of shoulder function, especial...

The acromion (AC) is a strong bone that functions as a shield, protecting the structures of the subacromial region. It absorbs and dissipates the forces applied to the shoulder region;1 however, high energy force may produce fractures, as well as other severe lesions. Therefore, diagnosis may not be immediately performed due to the necessity of assessing associated lesions.2 Acromion fracture i...

Disorders of the shoulder complex can be accompanied by changes in the movement pattern of the scapula. However, scapular motion is difficult to measure. A possible non-invasive method for dynamic three-dimensional kinematic measurement of the human scapula is the use of a marker cluster placed on the flat part of the acromion. A small light-weight acromion marker cluster (AMC) is presented in ...

We report on a very rare case of co-existence of os acromiale with suprascapular osseous bridge in a dry scapula. The frequency of os acromiale alone ranges from 1.3 to 15%, while the frequency of suprascapular osseous bridge varies between 0.036% and 12.5%. We review the relative literature and emphasize the fact that such knowledge is important for a physician in order to avoid misdiagnosis o...
