Embryology - Anatomy - Morphometry of the glenoid.
P Mansat, MD, PhD
The scapula forms the posterior part of the shoulder girdle. It is a flat, triangular bone, with two surfaces, three borders, and three angles.

Evolution in the design of glenoid component in shoulder arthroplasty. Historical review and future.
Denis Katz, MD
In 1970, 20 years after his first humeral arthroplasty , Charles Neer completed his prosthesis by adding a keeled cemented glenoid component made entirely of polyethylene .

Design of glenoid component: why?
P Mansat, MD, PhD
Charles Neer a initialement décrit les arthroplasties de l’épaule sans remplacer la glène. Cependant, après une expérience de quelques années, il conçut un implant glénoïdien en raison de la persistance de douleur dans les suites des hémiarthroplasties

Trends in glenoid component design
JM Glasson, MD
Glenoid replacement in shoulder arthroplasty has a very recent history. The first modern report of a serie was presented by CS Neer in 1974.

Exposure and Preparation
K. ELKHOLTI
Exposition of the glenoïd is a difficult stage of the preparation in shoulder arthroplasty and the topics is based to give some tips and tricks for this procedure.

Glenoid Dysplasia classification
Jean kany
So far glenoid implantation still remains a challenge and is technically demanding even for an experienced shoulder surgeon. Each shoulder pathology has its own evolution.

CLASSICATION DES PERTES DE SUBSTANCES OSSEUSES GLENOIDIENNES CONSECUTIVES A UN DESCELLEMENT D’IMPLANT PROTHETIQUE
Philippe SAUZIÈRES
La survie à long terme des prothèses totales de l’épaule, qu’elles soient inversées ou non, est essentiellement liée à celle de l’implant glénoïdien, qu’il soit en polyéthylène ou metal-back.

« Should we worry about radiolucent lines in glenoid components? »
Dr R. GUINAND, MD
The appearance of radioluccent lines (RLL) around the glenoid component of TSA is a well-known radiologic phenomenon.

CT scan evaluation of glenoid component fixation: a prospective study of twenty seven minimally cemented shoulder arthroplasties
A. Vidil, Ph. Valenti, F. Guichoux, JH. Barthas
Glenoid component failure is the most common complication of total shoulder arthroplasty.
It can be correlated with failure of the component itself to resist wear and deformation, failure of fixation or failure of the glenoid bone.

4 years follow up of 29 embedded polyethylen mini glenoid in total shoulder arthroplasty for centered arthritis.
JM. Glasson, Mark Ross, Phil Duke
Total shoulder arthroplasty gives the most predictable and satisfying results in centered arthritis with an intact rotator cuff. However, long term outcomes of the glenoid is often a concern to the surgeon.

New design of a cementless glenoid component in unconstrained shoulder arthroplasty. A prospective analysis of 143 cases.
D.Katz, J.Kany, P. Valenti, P. Sauzières, P. Gleyze, K. El Kholti
The uncemented glenoid implants in total anatomical shoulder arthroplasty are likely to be accused of problems like dissociations, secundary rotator cuff tear, wear of polyethylene (PE).

“Glenoid or not glenoid in anatomic arthrosplasty”
Achour DEGHRAR
La chirurgie prothétique de l’épaule est en plein essor. Les résultats publiés à court et moyen terme sont satisfaisant. Le taux de complications varie d’une série à l’autre.

Does the non-fixed Pyrocarbon Interposition Shoulder Arthroplasty allow to avoid glenoïd complications for the treatment of primaray osteoarthritis ?
Jérome Garret MD, Arnaud Godenèche MD, Sophie Grosclaude MD, Christophe Lévigne, Lionel Neyton MD, Gilles Walch MD
Conservation of the glenoid stock is the main challenge of shoulder prostheses; the choice between total shoulder arthroplasty and hemiarthroplasty is a dilemma

Pitfalls and mistakes with glenoid component implantation
Jean Kany
Glenoid component failure is the most common complication of total shoulder arthroplasty.
As a result components are unable to replicate essential properties of the normal glenoid articular surface to achieve durable fixation to the underlying bone, to withstand repeated eccentric loads and glenohumeral translation and to resist wear and deformation.

COMMENT TRAITER UNE GLENE BICONCAVE OU DYSPLASIQUE. CHOIX D’UNE PROTHESE HUMERALE SIMPLE, TOTALE OU INVERSEE.
Philippe SAUZIÈRES
Il faut d’abord différencier les types B2 ou C post-arthrosiques, des types C dysplasiques.
Toutefois quelle qu’en soit l’origine, les glènes de de type B2 ou C sont particulièrement difficiles à traiter. De nombreux aspects entrent en jeu et s’ajoutent les uns aux autres.

Hemiarthroplasty versus Total shoulder arthroplasty
Ph Valenti
Hemiarthroplasty is usually indicated in patients with an intact cuff and no glenoid wear. The best indication is an early stage of avascular necrosis.

Does the pre operative glenoid wear influence the results of unconstrained total shoulder arthroplasty using a cemented 4 pegs glenoid component? A prospective multicentric review of 121 prostheses with more than 2 years of follow-up
D. Katz, J. Kany, P. Valenti, P. Sauzières, P. Gleyze, K. El Kholti
It has been advocated in the literature that the posterior pre operative glenoid wear influences the quality of clinical and radiological results of total shoulder arthroplasty.

Glenoid revision and reimplantation
Ph Valenti
Glenoid component loosening is the most common complication in total shoulder arthroplastie and represents 25% of all complications related to TSA.

Scapular Notching: How to prevent? How to treat?
Ph Valenti
Scapular notching is the main complication of the reverse shoulder arthroplasty. Scapular notching is present in more than half of the cases using the Grammont reverse shoulder design.
