RSP®

Description

• Lateral, anterior, and posterior fins to provide additional resistance to tuberosity migration and rotational stability
• Single piece stem/shell construct saves OR assembly time
• Stem diaphyseal diameters in 6, 7, 8, 10 and 12mm for anatomic variability
• Distal grooves providing anti- rotation and aiding in implant stability
• Medial suture hole for securing structural bone graft
• Metaphysis coated with plasma spray to enhance osteointegration
• Anatomic humeral neck-shaft angle reduces potential for inferior scapular notching
• Single cup diameter accepts multiple articular insert diameters giving intra- operative flexibility
• Multiple suture hole options (lateral, anterior, and posterior fins with suture holes) available to secure structural bone graft and facilitate tuberosity fixation/repair
• Low profile metaphyseal neck which allows for anatomic positioning of tuberosities and facilitates use of bone graft
• Roughened surface on back of cup provides additional friction to prevent tuberosity migration

Enhanced Fixation

P2, backed by the largest porous coating animal study in the world, creates instant micro-fractures in the trabeculae upon initial bite to the bone, which causes an instantaneous bone in-growth reaction.¹Our one piece, monolithic RSP baseplate design provides 2000N or 10X more compression than a pegged baseplate design², providing stable initial fixation as well as ideal conditions for bony ingrowth for long-term fixation.

Traditional and +4mm Socket Inserts

Both traditional and +4mm inserts are available in 32, 36, 40 and 44mm in standard and semi-constrained providing various options of height, diameter, and constraint.

8mm Spacer

This 8mm Spacer is screwed into the Monoblock Stem and with a traditional insert provides 8mm of humeral prothesis build-up.

RSP Monoblock Hemi-Adapter

This Hemi-Adapter is screwed into the Monoblock Stem and with a Turon humeral head converts the reverse stem to a hemi-arthroplasty prosthesis.

Seven Glenospheres

With a distinct center of rotation in each size for management of complex anatomies.
