Acromion process of the scapula

It is an important landmark of the skeletal system and a muscle attachment point essential to the function of the shoulder joint. In 72 of the specimen the glenoid.

Recently acromion fractures are seen at the rate of 569 as the complication of reverse shoulder arthroplasty 2.

Acromion process of the scapula. The acromion process is the bony structure on top of the scapula. The acromion process also known as the acromion is a bony structure on the top of the scapula or shoulder blade. It arises from a ridge that horizontally crosses the upper portion of the scapula on the back side and protrudes at the peak of the shoulder forming a club-like shape.

The acromion process is an important process of the shoulder blade or scapula which stabilizes the shoulder and allows for a broad range of movement in different vertebrate animal species. The acromion of the scapula is a large bony projection on the superior end of the scapula. It is an important landmark of the skeletal system and a muscle attachment point essential to the function of the shoulder joint.

The acromion also forms the acromioclavicular AC joint with the clavicle. The acromion process is the elongated and flattened process of scapular spine. The scapular morphometry is an important factor related to impingement syndrome of the shoulder joint.

The acromion process is the lateral projection of the scapula spine that extends anteriorly. Fractures of the scapula are uncommon injuries and account for 3 of all shoulder fractures 12 while isolated acromion fractures occur rarely and account for only 9 of all scapular fractures 3. Acromion fractures constitute 816 of scapula fractures 1.

Recently acromion fractures are seen at the rate of 569 as the complication of reverse shoulder arthroplasty 2. Acromion fractures may occur as a result of shoulder trauma and overuse injuries. Acromion fractures may occur with glenoid process scapula or clavicle distal.

FIGURE 5-4 Acromion process of the scapula. After palpating the coracoid process of the scapula move back to the clavicle and continue palpating the clavicle laterally distally once again until you reach the acromion process of the scapula. The acromion process of the scapula is at the far lateral end ie the tip of the shoulder.

Certain types of scapular fractures may need surgery. Fractures of the glenoid articular surface in which bone has moved out of place displaced Fractures of the neck of the scapula with a lot of angulation. Fractures of the acromion process that cause the arm bone to hit against it impingement syndrome.

Scapular fractures are uncommon and correspond to 05-1 of all body fractures. The study objective was to present a rare case report of a fracture lateral acromion and angle of the scapula spine and review of the literature on which will greatly contribute to diagnosis and treatment. The acromion process is at the end of this spine which forms an integral part of the shoulder joint along with the coracoid process of the scapula.

However typically most acromial fractures are associated with more complex fractures of the scapula andor clavicle and may also involve the suspensory ligament complex. Any disruption of the ligament complex is treated as described in the section of LSSS. Most of the acromion is cancellous bone and provided poor fixation for screws.

The acromion plural. Acromia also known as the acromial process is a small projection of the scapula that extends anteriorly from the spine of the scapula. Gross anatomy It forms the acromioclavicular joint ACJ with the lateral third of.

The acromion is a large bony projection on the superior end of the scapula. Acromion fractures may occur as a result of shoulder trauma and overuse injuries. Acromion fractures may occur with glenoid process scapula or clavicle distal fractures and.

The scapula has three processes. The acromion the spine and the coracoid process. Muscle attachments to these landmarks are covered in the Muscles section.

The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches. Scapula ossifies from 1 primary centre and 7 secondary centres of ossification 2 for coracoid process 2 for acromion1 each for glenoid cavity inferior angle and medial border. Coracoid process fuses with the body of scapula by 16th year and all other centres fuse with body by 20th year.

The acromion is the lateral projection from the spine of the scapula. The spinoglenoid notch is the gap between the acromion and the glenoid neck of the scapula. The suprascapular nerve and vessels pass through the notch en route to the infraspinatus.

To analyze the anatomical basis of the scapula cobra shaped 13 square shaped and 56 intermediate acromion os acromiale coracoid process coraco-acromial type. The scapulas coracoid process and the coraco- arch and glenoid cavity in Turkish adults. Acromial arch were measured.

In 72 of the specimen the glenoid. The acromion process projects forwards almost perpendicularly from the lateral end of spine of scapula. The acromion process is associated with a variety of ailments in the shoulder joint.

As morphometry of the Acromion process of the scapula is an important factor implicated in impingement syndrome of the shoulder joint the. Gets inserted superiorly along the spine acromion process and clavicle. It helps to elevate and rotate the scapula during protraction of the humerus beyond 90 degrees.

Insert into the superior angle and medial border. They help in elevating the scapula. The spine ends in the acromion a process that articulates with the clavicle or collarbone in front and helps form the upper part of the shoulder socket.

The lateral apex of the triangle is broadened and presents a shallow cavity the glenoid cavity which articulates with the head of the. Educational video describing the anatomy of the coracoidThe coracoid is a hook shaped bony process that is attached to the neck of the scapula.
