RSP® Monoblock
A forward-thinking reverse

The latest addition to the Reverse family; the RSP monoblock is a one piece stem/shell design with suture holes and fins to address proximal fractures. This stem captures the advantages of the traditional RSP and has the benefit of expanded indications.

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.

ICJR Live Surgery with Match Point and RSP

  • 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
