What is a Metaglene?
What is a Metaglene?
The metaglene consists of a. base plate that is secured by screws to the native. glenoid. The glenosphere is the rounded portion. of the prosthesis that is attached to the metaglene.
How many different Metaglene central peg lengths are available with the Delta Xtend ™ shoulder system?
The size of the glenoid vault should be assessed inferiorly in particular to ensure that all four metaglene screws can be placed within glenoid bone.
Where is glenoid fossa?
The glenoid fossa of the scapula or the glenoid cavity is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.
What is scapular notching?
Scapular notching is a common radiographic finding occurring after reverse total shoulder arthroplasty, and it refers to an erosive lesion of the inferior scapular neck because of the impingement of the humeral implant during adduction.
What connects with the glenoid fossa?
Glenohumeral ligaments- Composed of a superior, middle, and inferior ligament, these three ligaments combine to form the glenohumeral joint capsule connecting the glenoid fossa to the humerus.
Where is the scapular notch?
Anatomical terms of bone The suprascapular notch (or scapular notch) is a notch in the superior border of the scapula, just medial to the base of the coracoid process.
Where does the Subscap attach?
The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint.
What is glenoid fossa?
The glenoid fossa of the scapula or the glenoid cavity is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. This cavity forms the glenohumeral joint along with the humerus. This type of joint is classified as a synovial, ball and socket joint.
What are the components of a metaglene prosthesis?
The metaglene component is HA coated and is intended for cementless use with the addition of screws for fixation. The modular humeral stem and humeral epiphysis components are HA coated and intended for cementless use. All other metallic components are intended for cemented use only.
How big should the glenoid bone be for a metaglene?
Although this assessment is somewhat subjective, there must be enough glenoid bone to ensure adequate purchase of the screws anchoring the metaglene. Ideally, the glenoid bone stock should be at least 2 cm in depth centrally, between the articular surface and the region where the glenoid narrows at the scapular neck (, Figs 9, ]
