There are 4 types of os acromiale with the meso-acromion being the most common and difficult to treat. The excision of a pre-acromion arthroscopically or open usually produces satisfactory results. However, the open excision of a meso-acromion can lead to persistent pain, deltoid weakness, ...

An inferiorly directed load to the anterior acromion was applied at a rate of 60 mm/min until failure. Ultimate failure load, stiffness, and fracture pattern were recorded and analyzed. Results Ultimate failure load was significantly higher for the TB group (mean, 336 N ± 126 N; ...
