Total Shoulder Replacement
Product Description
The anatomic Total Shoulder Arthroplasty (TSA) is indicated when both sides of the scapulo-humeral joint are worn out, and when the rotator cuff remains intact and with no sign of motricity deficiency. The TSA requires a good glenoid bone stock and will be contra-indicated whenever there pre-exists a permanent instability in the joint.
The UNIC anatomic system is characterized by:
- Compatible with all and any humeral base: primary, fracture or revision, cemented or cementless.
- Oval humeral heads available in 5 combinations of diameter/thickness.
- Efficient multi-position Head offset management based on twin crossed ratchets and twin taper modulus.
- Optionnal 6° angled modulus to fine tune for increased varus/valgus or ante/retroversion.
- Identical mismatch through the range unabling match of all heads with all sizes of glenoid.
- Low 2mm mismatch reduces sheer stresses on the glenoid component.
Body
Inlay humeral prosthesis designed to allow for reproducible conversion from TSA to RSA.
Stem
Modular platform stem with diaphyseal fixation allows for version adjustment in revisions.
Glenosphere
4 glenospheres with +2 or +5 lateralization; 4mm of optional eccentricity.
Baseplate
A comprehensive 3D CT database was used to develop a baseplate intended to maximise stability and fit patients of all sizes.
