The UNIC STEMLESS implantable device is designed to treat osteoarthritis and osteonecrosis of the humeral joint when associated with an efficient rotator cuff for active patients. The UNIC STEMLESS implantable device is specially designed for fixation in the cancellous bone of the proximal humerus. It can be used as an hemi-arthroplasty of the shoulder joint, or associated with a glenoid anatomic resurfacing with the anatomic glenoid components of the conventional UNIC system.
The UNIC STEMLESS humeral component is designed for cancellous fixation without cement. The humeral component is made out of additive printing technology and results in nano-structured porous and interconnected trabeculaes intended to favour in-depth osseointegration. The additional proximal HAcoating enhances the secondary fixation process.
Should the UNIC STEMLESS be revised, the implant has been designed to facilitate the introduction of bone chisels along the 4 intra-osseous flanges, leaving the humeral bone near-genuine for the implantation of a conventional stemmed primary humeral implant.
