Features and Benefits

Features and Benefits of PROMOS Shoulder

PROMOS is a Shoulder Arthroplasty PLATFORM with unified design for standard, reverse and fracture indications. Implant modularity offered by this system allows the surgeon to decide inside the OR whether to perform a primary or a reverse shoulder procedure. 

In-situ Anatomical Reconstruction

In situ assembly of the PROMOS components matches the implant to the patient’s anatomy:

  • A custom fit every time
  • Positions the prosthetic humeral head to the center of the glenoid by restoring the patient’s retroversion and humeral head height
  • Allows for rotational and translational movement of the humeral head to more closely approximate the anatomy

Seamless Convertibility

A well-fixed stem shouldn’t have to be removed.

  • Less harmful to the patient
  • Easier to perform for a surgeon than a full revision
  • Lower cost to healthcare providers

Hassle-Free Fracture Fixation

Cementless fixation of humeral component improves the predictability of your proximal humeral fracture fixation in arthritic patients

  • The PROMOS system features easy in situ adaptability with an anatomically sized humeral head and cementless stem fixation. 
  • Unique modular body design simplifies head height adjustment and allows secure, anatomical tuberosity fixation.

Unified Instrumentation

  • One instrument set for reverse, total shoulder and fracture repair
  • The surgeon learns and performs each technique using one instrument set regardless of the patient’s indication
  • Adaptability designed to simplify your procedure – not to add unnecessary complexity

Simple Revision

With PROMOS REVERSE, you can convert rather than revise

  • Avoid stem removal which may cause bone loss and fractures
  • Second surgeries can be made less difficult
  • Avoid other possible complications caused by stem removal

High Torsional Stability

  • Dual-taper, rectangular cross section achieves primary stability and builds on the Zweymuller anchorage philosophy proven by 25+ years of successful diaphyseal fixation
  • Biomechanical testing of rectangular humeral shaft prosthesis proved to offer higher torsional stability without increased fracture risk*

Implant Information

Humeral Stem: The Foundation of PROMOS

Cementless

  • Diaphyseal fixation based upon the Zweymuller hip philosophy.
  • Rotational stability: dual tapered, rectangular cross-section.
  • Grit-blasted surface promotes on-growth.
  • Half-sizes allow additional height adjustment.

PROMOS Shoulder Replacement Stems

Standard Body: Adjusts Height and Version

  • Allows fine adjustment of version after stem is fixed.
  • Capable of rotating 360o, anatomy permitting. 
  • 3 heights:  30mm, 35mm, 40mm
  • 135o neutral inclination

PROMOS Body

Inclination Set: Provides Offset and Axis of Rotation

  • Humeral head can be positioned to precisely match the anatomic head; Morse taper.
  • 4 neck lengths provide variable offset: 20mm, 22mm, 24mm, 26mm
  • 360º rotation of the inner cone as well as the sleeve allows inclination adjustment of +/- 12º; body is fixed at 135º, which means range of inclination: 123º - 147º

PROMOS inclination shoulder replacement set

Humeral Head: Precise Coverage of the Osteotomy

  • Location determined by stem height, body height, inclination height and angle
  • Height increases proportionally with radius.
  • Morse taper

PROMOS Humeral Head

Glenoid: Pegged Glenoid for Stability

Cemented

4 pegs with cement pockets for excellent stability

Anatomic shape

Sizes 1 – 4 for ideal coverage of the glenoid fossa

3 – 5mm mismatch between humeral head and glenoid radius.

Choice of 4 radii (for humeral heads)

PROMOS Glenoid

Reverse Body:  Avoid Stem Removal in Revision Procedures

Determines height and retroversion

3 heights (5mm, 10mm, 15mm)
2 diameters to match glenosphere (36mm, 42mm)

Morse taper with set screw

155º inclination to prevent subluxation
Adjusts the center of rotation; lengthens lever arm of the deltoid

PROMOS Reverse body

PE Insert: Adjustable Offset and Height

Articulates with the glenosphere

Affects offset and height.
3 heights (6mm, 9mm, 12mm)
2 diameters to match the glenosphere (36mm, 42mm)

PROMOS PE inserts

Glenosphere: Eccentric Head to Avoid Scapular Notching

Concentric and 5mm Eccentric

Eccentric head reduces the possibility of scapular notching.

2 diameters (36mm, 42mm)

Select as large as possible

Engages glenoid baseplate with a Morse Taper and set screw

PROMOS shoulder glenosphere
Glenoid Baseplate:  Anatomic Shaped and Fixed-angled Bone Screws

  • Anatomic shape; curved for stability
  • One size corresponding to the Size 1 glenoid fits most of the glenoids.
  • 2 fixed-angle, locked glenoid bone screws provide solid primary fixation.
  • 6.0mm screws in 5 lengths (20mm, 25mm, 30mm, 35mm, 40mm)
  • Ti plasma spray coating provides secondary fixation.
