- Replacement of an «anatomic» prosthesis with a «reversed» prosthesis
- Conversion of a hemi-arthroplasty into a total arthroplasty
- Increasing the size of the stem (length and/or diameter)
- Replacing a glenoid prosthesis
- Replacing a glenoid insert
- Replacing a competitor’s prosthesis
- In rare cases, removing a «reversed» prosthesis and replacing it with an «anatomic» prosthesis
• Additional indications for the monoblock range:
- Massive loss of bone matter
- Proximal fracture of the humerus
- Destruction of the bone
- Local bone tumors
- Replacing a modular prosthesis

Anatomical corolla
• The anatomic corolla is made of Cobalt Chrome with Porous T40 Titanium and Hydroxyapatite coating. It consists of 6 branches, and a taper to fix the anatomical heads.
• The corolla is impacted into the centre of the humerus, with a stem less fixation allowing minimal loss of bone stock.
• The corolla is implanted by referencing the patients natural anatomy so it is always positioned at the indi-vidual patients normal offset and inclination.
• Four sizing options.

Cemented Full PE glenoid
• Made from ArCom polyethylene with an anatomical shape and following design considerations :
- a flat periphery for improved stability
- a central convex section for bone stock preservation
- an original keel with 3 pegs for good cement fixation
• A minimal polyethylene thickness of 3 mm.
• 4 sizing options.
Anatomical heads
• Available in two versions :
- centred
- eccentric with 5 mm offset
• The head is fixed on the corolla with a taper.
• In 6 diameters for each version.

Cementless Metal-back
glenoid baseplate
• The glenoid baseplate is made in Porous Titanium TA6V Macrobond and Hydroxyapatite.
• The glenoid baseplate can receive either an anatomical insert of polyethy-lene or a reverse head.
• The posterior surface of the baseplate includes :
- a flat peripheral surface to maximise stability
- a central convex section to preserve the bone stock
One baseplate for the two options : anatomic and reverse
- a central keel with a possibility of a compression screw 1 , or a extension keel 2 in case of revision or poor bone quality
- primary fixation from anterior and posterior screws and with 2 optional antero posterior spikes for medio lateral fixation, which can be replaced with locking screws for greater fixation 3

• The locking screws, diameter 4.5 mm in 7 lengths are manufactured from TA6V Titanium Alloy.
• The glenoid preparation for both glenoid implants, cemented and cementless, is made with the same instrumentation.
• 4 sizing options.

Reverse corolla
• Cobalt Chrome with a Porous Titanium T40 and Hydroxyapatite coating. The PE insert is locked in the reversed corolla
with a RingLoc system.
• The corolla is impacted into the centre of the humerus. As the prosthesis is stemless there is no injury to the intramedullary canal.
• 4 sizing options.
Reverse head
• Cobalt Chrome, available in 2 diameters :
- Diameter 36 with the glenoid 0 and 1
- Diameter 41 with the glenoid 2 and 3
• Fixed on the baseplate with a central taper.
• Center of rotation lateralized by 3 mm.

Reverse insert
• ArCom polyethylene available in 4 thicknesses : 6, 8, 10 and 12 mm.
- The sizes 0 and 1 are 36 mm in diameter.
- The size 2 is available in 36 mm and 41 mm options
- The size 3 is 41 mm in diameter
The stem
• The optional humeral stem can be used in cases of poor bone quality or when additional stability is required 1 .
• Cemented in proximal humeral fracture cases.
• In Cobalt Chrome, available in 5 lengths and 6 diameters .
• The stems can be implanted with or without cement.
• The proximal stem has a Titanium porous coating for bone ingrowth.
• The distal part of the stem is polished and has 2 anti-rotational flutes for a better fixation in cement.
• When the corolla is used without stem, it is advisable to use the “small stem” 2 .
