Stryker LFIT V40 Femoral Head

U.S. District Court for the District of Massachusetts

The Stryker LFIT V40 femoral head MDL, centralized in the District of Massachusetts in 2017 before Judge Indira Talwani, consolidates claims that a specific femoral head component, compatible with and sold alongside multiple different Stryker hip stem systems, is prone to corrosion and fretting at its taper connection, producing elevated metal-ion levels and, in many cases, revision surgery. Centralizing the claims made sense given the shared component-level defect theory, even though the component was used across a range of different hip systems rather than a single integrated product.

That multi-stem-compatibility structure is what most distinguishes this docket, procedurally, from Stryker's separate Rejuvenate and ABG II hip implant litigation, which involved an integrated modular stem system rather than a single component sold across multiple platforms. With 47 actions still coordinated, this is a moderately sized, mature docket where duration and resolution risk are shaped by individualized questions about which specific stem-and-head combination a claimant received and whether that combination's corrosion and metal-ion findings support the alleged causation theory, rather than by a single uniform product-defect question applicable identically to every claim.

Because the component was used across multiple stem systems, general-causation evidence developed in this docket may not translate uniformly across every claim, which is a distinct structural feature relative to a single-product hip-implant MDL where causation evidence applies more consistently docket-wide. For claims that do not resolve through negotiated settlement, remand to the originating district for trial remains the standard backstop under the federal MDL framework.

Criterica Intelligence's platform tracks this kind of component-versus-integrated-product distinction as a meaningful structural variable in device litigation, applying that same specificity across the full population of active MDLs rather than treating every hip-implant docket as structurally identical.

Frequently Asked Questions
Why is this a separate MDL from Stryker's other hip implant litigation?

It centers on a different component, a femoral head compatible with multiple stem systems, with its own corrosion and fretting defect theory, distinct from the integrated modular stem at issue in Stryker's separate Rejuvenate/ABG II docket.

Does causation evidence apply uniformly across every claim in this docket?

Not necessarily. Because the component was used across multiple stem systems, a claim's specific combination affects how directly docket-wide causation evidence applies, unlike a single-product hip MDL where causation evidence is more uniformly applicable.

What drives resolution risk in this docket?

Individualized questions about the specific stem-and-head combination a claimant received and whether that combination's corrosion and metal-ion findings support the alleged causation theory, rather than a single uniform defect question.

What happens to a claim that doesn't settle?

It proceeds toward remand to its originating district for trial, consistent with standard federal multidistrict litigation procedure.
