Full title and description

ASTM F1378-18e1 — Standard Specification for Shoulder Prostheses. This specification establishes requirements and performance-related guidance for shoulder prostheses (total and hemiarthroplasty), including materials, manufacturing and marking, modular connections, mechanical strength, corrosion resistance, wear, range of motion, and related test methods used to evaluate glenoid and humeral components.

Abstract

ASTM F1378-18e1 provides a short specification for shoulder replacement components used to provide functioning articulation of the glenohumeral joint. The standard covers constrained, partially constrained and unconstrained designs, includes modular prostheses (but not custom devices), and prescribes minimum mechanical, corrosion, biocompatibility and wear-related performance expectations as well as related test practices for component verification. The standard is used to guide design, testing and regulatory documentation for shoulder arthroplasty implants.

• Publication date: 2018 (designation -18 with editorial change e1; ASTM catalog lists the F1378-18 edition and associated editorial change).
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: 11.040.40 — Implants for surgery, prosthetics and orthotics (medical equipment / orthopedic implants).
• Edition / version: F1378-18e1 (2018 edition with editorial change e1).
• Number of pages: 6 pages (ASTM bibliographic record for F1378-18).

Scope

The standard covers shoulder prostheses intended for total shoulder arthroplasty or hemiarthroplasty that provide articulation through glenoid and humeral components. It includes modular prostheses (but excludes custom devices) and specifies SI units. The scope addresses mechanical and material requirements and references associated test methods and related ASTM standards for surgical implants.

Key topics and requirements

• Definitions and classification of shoulder prosthesis designs (constrained, partially constrained, unconstrained).
• Material and manufacturing references for implant alloys, ceramics and UHMWPE (referenced ASTM material specifications and practices).
• Mechanical strength and fatigue requirements for humeral and glenoid components, including stemmed component fatigue testing.
• Wear, fretting and corrosion considerations for modular connections and taper junctions; guidance for wear testing and fretting assessment.
• Requirements and test methods related to range of motion, impingement, scapular notching, and glenoid locking mechanisms (static shear/locking tests and disassembly strength for modular liners).
• Marking, labeling, and documentation expectations to support traceability and regulatory submissions.

(Key topical details and referenced test practices appear in the standard and in items identified for revision to align performance requirements with current regulatory/technical expectations.)

Typical use and users

Primary users include orthopedic implant designers and manufacturers, mechanical and biomedical test laboratories, quality and regulatory teams preparing premarket documentation, and procurement/specification engineers. Clinicians and hospital technology assessment groups may consult the standard when comparing implant designs or evaluating device labeling and test evidence. The standard is commonly used to support regulatory filings (for example, FDA recognized consensus standards listings).

Related standards

F1378 references and is used alongside numerous ASTM standards and practices relevant to implant materials and testing, including (examples) F75 (CoCr alloy castings), F136 (Ti–6Al–4V ELI for implants), F648 (UHMWPE for surgical implants), F86 (surface preparation and marking of metallic surgical implants), and related test methods for corrosion, shear testing and wear. It also complements device-specific test standards and newer methods developed for modular connection fatigue and glenoid locking evaluation.

FAQ

Q: What is this standard?

A: ASTM F1378-18e1 is a consensus specification that sets material, performance and testing expectations for shoulder prostheses (total and hemiarthroplasty), including guidance on mechanical strength, wear, corrosion and modular-connection behavior.

Q: What does it cover?

A: It covers design classes of shoulder implants (constrained, partially constrained, unconstrained), modular prostheses (not custom devices), referenced materials and practices, and test/performance requirements such as fatigue strength, wear and fretting evaluations, range-of-motion considerations, and locking/disassembly strength for modular components.

Q: Who typically uses it?

A: Implant manufacturers, test laboratories, regulatory affairs professionals preparing submissions, and engineers involved in design verification and quality assurance. Clinicians and hospital evaluators may use it for comparative assessment.

Q: Is it current or superseded?

A: The designation F1378-18e1 is the 2018 edition with an editorial change (e1) and is listed as a recognized consensus standard by the U.S. FDA (entry date Dec 23, 2019). A formal revision work item to update the standard was opened in 2026, indicating active maintenance; consult ASTM or national standards providers for any newer approved edition after 2026.

Q: Is it part of a series?

A: It sits within ASTM Committee F04 (Medical and Surgical Materials and Devices) and is associated with other orthopedic implant standards and test methods (many of which are cited inside F1378), but it is a standalone specification for shoulder prostheses rather than a numbered series.

Q: What are the key keywords?

A: Shoulder prostheses, glenoid, humeral component, modular, fatigue strength, wear testing, fretting corrosion, implant materials, ASTM.
