In brief
What should readers understand about The STRYDE Nail and Weight-Bearing Internal Lengthening Devices?
What the STRYDE nail was, why it was withdrawn from the market, what corrosion and osteolysis findings led to the recall, and the current state of weight-bearing internal lengthening nail development.

Current Status in One Sentence
STRYDE is not a current U.S. implant option: the FDA states that stainless-steel Precice devices, including STRYDE, remain recalled and should not be implanted. PRECICE MAX is a separate titanium system with 510(k) clearance and a separate Class II recall covering specified catalog and lot combinations. Do not treat it as an automatic STRYDE successor or infer the status and load limit of a particular unit from the family name. [1][2][4]
Why STRYDE Mattered
STRYDE was a stainless-steel magnetically driven lengthening nail designed to tolerate higher loading than earlier titanium PRECICE configurations. Greater permitted loading could change transfers, walking practice, and daily independence. Those intended advantages must be considered alongside the later biocompatibility concerns and recall.
What Follow-Up Studies Reported
A matched-pair analysis reported osteolysis in 31 of 48 STRYDE segments versus 1 of 91 PRECICE segments. The study also reported implant failure and pain findings, while observing that osteolysis generally resolved after implant removal. Observational results do not establish that every recipient will have the same outcome. [3]
FDA Guidance
The FDA's June 2023 update says stainless-steel Precice Bone Transport, Plate, and STRYDE devices remain recalled from the U.S. market due to adverse events related to potential biocompatibility concerns and should not be implanted. The same update distinguishes the titanium PRECICE IMLL system and reminds clinicians to follow its current instructions, including removal after one year. [1]
PRECICE MAX Has a Separate, Lot-Specific Recall Record
PRECICE MAX received 510(k) clearance in December 2023. The manufacturer initiated a recall on September 30, 2024 over potential design, manufacturing, and validation-documentation issues. The FDA Class II record lists specified catalog and lot combinations, remained open when updated on July 14, 2026, and tells customers to stop using and return affected unimplanted devices. The record does not by itself establish that every later or current PRECICE MAX unit is recalled or commercially available. [2][4]
A product described as stronger or designed for higher loading is not automatically available, unrecalled, appropriate for a particular patient, or permitted for full loading in every phase.
How to Verify a Weight-Bearing Claim
- Ask for the exact model and diameter, not only the brand family.
- Read the current instructions for use and recall record for the country of treatment.
- Clarify whether the limit applies to one nail, one limb, or total loading with bilateral implants.
- Confirm how the limit changes during distraction and consolidation and after any complication.
- Follow the treating surgeon's written restriction when it is stricter than a device maximum.
