The glenoid component is for use with bone cement only.
Device Story
Modular shoulder prosthesis system; restores shoulder motion and eliminates pain. Components: glenoid (UHMWPe) and modular humeral (titanium alloy stem/body, CoCrMo head). Humeral assembly uses Morse taper; includes size 3.5 cementless stem, Monoblock stems (sizes 30, 35, 40mm), and varied humeral heads (14 sizes/eccentricities). Features face gear interface between inclination set and body. Used by orthopedic surgeons in clinical settings for total or hemi-shoulder arthroplasty. Provides structural replacement for damaged joint surfaces; improves patient mobility and reduces pain.
Clinical Evidence
Bench testing only. No clinical data provided. Design verification and validation performed per 21 CFR 820.30. Materials conform to ISO 5834-2, ISO 5832-3, and ISO 5832-12 standards.
Technological Characteristics
Modular shoulder prosthesis. Materials: UHMWPe (ISO 5834-2) for glenoid; Ti6Al4V (ISO 5832-3) for stems/bodies; CoCrMo (ISO 5832-12) for heads. Features: Morse taper connections, face gear interface, cementless/cemented options. Sterilization: Radiation (ISO 11137).
Indications for Use
Indicated for patients with advanced shoulder joint degeneration (degenerative, post-traumatic, or inflammatory arthritis), avascular necrosis of the humeral head, complex proximal humerus fractures, or functional impairment due to post-traumatic joint loss.
Regulatory Classification
Identification
A shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis is a device made of alloys, such as cobalt-chromium-molybdenum. It has an intramedullary stem and is intended to be implanted to replace the articular surface of the proximal end of the humerus and to be fixed without bone cement (§ 888.3027). This device is not intended for biological fixation.

#### E.3 Substantial Equivalence Claimed to Predicate Device
PROMOS® Modular Shoulder System, K032126 3.1
{1}------------------------------------------------
#### Device Description E.4
The modified PROMOS® Modular Shoulder System is intended to aid in the restoration of shoulder motion and elimination of pain. This device consists of two primary components, the glenoid component and the modular humeral component. The changes to the PROMOS® Shoulder that resulted in the modified PROMOS® Shoulder and are subject of this 510(k) include:
- Addition of size 3.5 humeral stem, cementless .
- Addition of six humeral ball heads R21 R26, with 4 mm eccentricity .
- Redesign of body and inclination set to add face gear to area between . inclination set and body
- Addition of three Monoblock stems, cementless, size 02/30, 35 and 40 mm .
- Various labeling changes .
The glenoid component has a spherical articulating surface with four pegs on the inferior surface for attachment to the bone. It is manufactured from ultra high molecular weight polyethylene (UHMWPe) according to ISO 5834-2:1998, Implants for Surgery - Ultra-High-Molecular-Weight Polyethylene - Part 2: Moulded Forms. The glenoid is available in four sizes with each size having three different spherical radii of curvature for a total of twelve glenoid components.
The modular humeral component consists of a distal stem, body, inclination set and humeral head. The distal stem is rectangular in cross-sectional shape, previously available in seven cemented and seven cementless sizes, and now available in seven cemented and eight cementless sizes. It is attached to the body via a Morse type taper.
The cementless and cemented stems are fabricated from titanium alloy (Ti6Al4V) according to ISO 5832-3:1996, Implants for surgery -- Metallic materials -- Part 3: Wrought titanium 6-aluminium 4-vanadium alloy.
The body is made of same titanium alloy as the distal stems and is available in three sizes. The body and inclination set have been redesigned to add a face gear to the area between the inclination set and body. As before the modified inclination set consists of three components: an inclination insert, an offset module, and a ball head screw.
The modular humeral heads are manufactured from wrought cobalt-chromiummolybdenum (CoCrMo) alloy according to ISO 5832-12:1996, Implants for surgery -- Metallic materials -- Part 12: Wrought cobalt-chromium-molybdenum alloy, previously available in eight different sizes/eccentricities, and now available in 14 different sizes/eccentricities.
{2}------------------------------------------------
Since cementless or cemented stems in size 01 may be too large for some patients, the company has developed a humeral stem, size 02. The narrow crosssection of a size 02 stem precluded a modular design, i.e., 02 size stem and a selection of bodies. As a result, the company implemented the size 02 as a Monoblock system with three different heights for body sizes 30mm, 35mm, and 40mm. The design of the cross-section is the same as mentioned above in the description of the distal stem and the stem is made of the same titanium allov. The proximal portion has also been redesigned to add face gear to the area between inclination set and body.
#### દર્શા Intended Use
The PROMOS® Modular Shoulder System is indicated for:
- Advanced degeneration of the shoulder joint as a result of degenerative, post-. traumatic or inflammatory arthritis
- . Avascular necrosis of the humeral head
- Complex fractures of the proximal Humerus .
- Functional impairment especially in the case of post-traumatic loss of the . joint configuration
The humeral component is intended for cemented or cementless use. The glenoid component is for use with bone cement only.
### E.6 Predicate Device Comparison of Indications for Use / Intended Use and Technical Characteristics
The comparison of the modified PROMOS® Modular Shoulder System was based on a review of the Design Control documentation for the design changes, relevant aspects of which are included in the company's 510(k) Premarket Notification, and information concerning the predicate device that was available to the company internally, i.e., PROMOS® Modular Shoulder System, K032126. The comparison considered technical characteristics and the indications for use / intended use. Bench testing was assessed.
#### E.7 Performance Data
