ASTM F1829-23 PDF

Full title and description

ASTM F1829‑23 — Standard Test Method for Static Evaluation of Anatomic Glenoid Locking Mechanism in Shear. This test method specifies an in vitro procedure for measuring the static shear disassembly force of modular anatomic glenoid components (articular insert and backing) used in anatomic total shoulder arthroplasty, to allow comparative evaluation of locking/retention mechanisms.

Abstract

ASTM F1829‑23 defines specimen preparation, test-fixture alignment, loading procedure and reporting for determining the static shear disassembly force between the articular insert and backing of modular, metal- or composite‑backed anatomic glenoid prostheses. The method is intended for comparative, reproducible laboratory evaluation and notes that in vivo loading differs from the test conditions; results are suitable for design comparisons but not direct prediction of clinical performance.

Scope

This test method covers a means to determine the static shear disassembly force of modular anatomic glenoid components (a separate articular insert and backing) fabricated from combinations of metal alloys, polymers and composites. It addresses specimen mounting, alignment, loading in shear, data recording and reporting in SI units, and states limitations and safety considerations for applicability to different implant designs. The method is intended for comparative laboratory evaluation rather than direct prediction of in vivo performance.

Key topics and requirements

• Definition of test specimen: modular anatomic glenoid comprised of an articular insert and metallic or composite backing.
• Objective: determine static shear disassembly (retention) force between insert and backing under controlled in vitro shear loading.
• Specimen preparation and fixturing rules to ensure reproducible alignment and load application.
• Test apparatus requirements and calibration practices (force measurement per ASTM practices where applicable).
• Loading protocol: displacement/force application in shear, data acquisition, and failure/disassembly criteria.
• Units and reporting: SI units required; detailed reporting to allow inter-laboratory comparison and assessment of design/material/manufacturing effects.
• Limitations and intended use: comparative bench testing only; does not replicate all physiological conditions.

Typical use and users

Used by orthopedic implant manufacturers (design and verification of modular glenoid locking/retention mechanisms), independent testing laboratories, research groups evaluating implant designs or materials, and regulatory reviewers assessing bench data submitted for shoulder arthroplasty devices. The standard is recognized in regulatory listings for orthopedic device testing and is typically cited in device dossiers and internal design validation.

Related standards

ASTM F1829‑23 references and is used alongside other shoulder/arthroplasty standards such as ASTM F1378 (Standard Specification for Shoulder Prostheses) and related ASTM test methods and practices for implant testing and force calibration. Users often pair F1829 with broader implant specifications and cyclic- or fatigue‑testing standards when performing a complete mechanical characterization.

FAQ

Q: What is this standard?

A: ASTM F1829‑23 is a test method that defines how to measure the static shear disassembly (retention) force between an articular insert and the backing of modular anatomic glenoid components used in total shoulder arthroplasty.

Q: What does it cover?

A: It covers specimen definition, mounting/fixturing, loading in shear, measurement and reporting of disassembly force, units (SI), and limitations; it is intended for comparative in vitro evaluation, not to directly predict in vivo performance.

Q: Who typically uses it?

A: Implant manufacturers, test laboratories, academic researchers studying implant mechanics, and regulatory reviewers evaluating bench test data for shoulder prostheses.

Q: Is it current or superseded?

A: Current — the designation F1829‑23 is the 2023 revision/edition (approved March 1, 2023) and is listed as an active/published ASTM test method. Users should confirm any later corrigenda or revisions with ASTM before relying on the text for formal test programs.

Q: Is it part of a series?

A: It is part of the ASTM F04 committee portfolio (Medical and Surgical Materials and Devices, Subcommittee F04.22 on Arthroplasty) and is commonly used together with related shoulder prosthesis specifications and test methods (for example, ASTM F1378 and other F04 test methods).
