What is a os acromiale?

Os acromiale is a developmental aberration in which the distal acromion fails to fuse. This aberration is often discovered incidentally but may present with a clinical picture similar to that of subacromial impingement syndrome.

How do I fix my acromiale os?

[9] Nonsurgical management has traditionally been the initial treatment of choice in all cases of os acromiale. [2] Failure of nonoperative measures may require surgical intervention. Surgical options include excision of the os acromiale fragment, subacromial acromioplasty and internal fixation.

Does os acromiale cause pain?

Os acromiale is an uncommon cause of shoulder pain with symptoms often resulting from an unstable meso-acromion. The associated pain may be due to impingement from the unfused fragment, a concomitant rotator cuff tear, or gross motion at the os acromiale site.

What does there is no os acromiale mean?

Os acromiale is a failure of fusion of the acromial process. It is usually asymptomatic and discovered by chance.

What causes os acromiale of shoulder?

Causes of os acromiale The acromion develops from four ossification centers or growth plates. The growth plates generally fuse by age 18 but can fuse as late as age 25. When there is failure of the growth plates to fuse an os acromiale develops.

What is an os acromiale of the shoulder?

What is meso os acromiale?

The os acromiale represents a failure of fusion between two of these apophyses [2]. The types of os acromiale are defined by the unfused segment immediately anterior to the site of nonunion [3]. For example, failed fusion between the meta-acromial and meso-acromion ossification centers is called a meso-acromiale [3].

What is ICD 10 acromiale?

Is os acromiale hereditary?

The second theory for the development of os acromiale is genetic. Sammarco12 reported 8% of os acromiale in a cadaveric study, with 33% involving bilateral cases. This rate of bilaterality increased to 62% in a study by Lieberson.
