Hemi-arthroplasty head with increased volume indicated in Cuff Tear Arthroplasty cases.
Whenever the glenoid bone highly worn out does not allow proper fixation of a glenoid base.
The increased volume/thickness of the CTA head enables the prosthesis to articulate with the sub-acromial surface.
A supero-lateral “cap” extends the articualr surface and prevents the rotator cuff from rubbing on the resected bone.
