VI. Comparison of Technological Characteristics
The Glenoid Polyaxial Non-Locking Screws and the predicate devices share the following characteristics:
- indications for use;
- head design (with exception of Medacta Locking Screw predicate, K170452); ●
- thread design;
- ROM:
- material of construction;
- biocompatibility:
- device usage:
- sterility;
- shelf life; and
- packaging. ●
The Glenoid Polyaxial Non-Locking Screws are technologically different from the predicate devices as follows:
- . sizes and lengths.
The subject Glenoid Polyaxial Non-Locking Screws have technological characteristics of the Medacta predicate device Glenoid Polyaxial Locking Screws (K170452) with the only exception of the Non-Locking mechanism, feature shared with the other predicates: the Non-Locking screws possess a cylindrical shaped head which allows for the insertion and placement of the implant into the dedicated seat of the baseplate, compressing it on the glenoid vault; on the other hand, the Locking screws own a "petal shaped" head which can also expand in order to lock its position into the baseplate.
The subject Glenoid Polyaxial Non-Locking Screws provide a wider range of lengths if compared to predicate devices and these length options do not represent worst cases because the length of the screws does not have any influence on the mechanical properties (torque resistance and pull-out strength).
Biocompatibility testing conducted on the predicate devices for the same or similar materials supports the biological safety of the Glenoid Polyaxial Non-Locking Screws. Subject and predicate devices are manufactured from the following material: Titanium Alloy (Ti-6Al-4V) ISO 5832-3:1996 Implants For Surgery - Metallic Materials - Part 3: Wrought Titanium 6-Aluminum 4-Vanadium Alloy.
This material has an extensive amount of biocompatibility data that has been provided in the listed predicate devices 510(k) submissions Medacta Glenoid Polyaxial Locking Screw (K170452), DePuy Delta Xtend™ (K062250 and K071379), Lima SMR™ Modular Shoulder Replacement System (K100858) and Wright Medical - Tornier AEQUALISTM REVERSED II Shoulder Prosthesis (K112144).
