Abstract:
Os acromiale is a failure of fusion between 1 or more ossification centers of the scapula and the acromion process. Pain can be caused by motion and impingement of the unfused segment. Several methods for the management of os acromiale have been described. Internal fixation is the most common surgical technique, followed by excision and acromioplasty. We present a novel technique for treatment of symptomatic os acromiale using arthroscopically-guided headless compression screws. This is a viable technique in the management of symptomatic os acromiale due to preservation of the periosteal blood supply and less concern for symptomatic hardware.

Self-Locking Screw
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
Frictional Forces on Screws
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...
Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
