In brief
What is PRECICE MAX, and can patients bear full weight with it?
PRECICE MAX is an internal magnetic limb-lengthening system with design changes intended to increase mechanical strength. Manufacturer testing and clinic loading statements do not establish an individual walking allowance. FDA clearance, an open specific-lot recall record, and dated clinic use reports must be checked separately.

Status checked October 7, 2026
Three records answer different questions
The FDA cleared the Precice Max System in December 2023. Its separate Class II recall record lists particular products and lots and was still marked "Open, Classified" when checked. A July 2026 clinic announcement reports use of the latest PMax. None of these records alone establishes the status of a device proposed for a particular patient. [1] [2] [4]
What is different from earlier PRECICE nails?
The FDA's K232267 summary describes a titanium-alloy system with larger nail and screw diameters than its predicate. Globus's current product page lists 10, 11.5, and 13 mm nails and larger distal screw holes with partially threaded screws. These are design descriptions, not evidence that every patient can walk without assistance. [1] [3]
Globus reports 2.6 times the dynamic bending strength and 1.3 times the rotational stability compared with Precice 2, supported by mechanical testing data on file. Those ratios describe the manufacturer's bench comparison. They do not mean 2.6 times the safe body weight, faster healing, fewer complications, or a proven advantage in cosmetic satisfaction. [3]
Does MAX mean immediate full weight bearing?
An implant's mechanical strength, its labeling, and a patient's permitted activity are separate matters. Ask for the current instructions for the exact nail and a written loading plan addressing implant size, bone segment, body weight, surgical configuration, and healing. This review did not verify a current MAX-specific instruction manual supporting one universal kilogram or pound allowance. Older PRECICE or STRYDE instructions and internet protocols are not substitutes.

| Dr. Dror Paley / Paley Institute - July 14, 2026 | The institute reports a completed procedure using the latest PMax and describes potential earlier full weight bearing. [4] | A dated clinic report, not an independent comparative cohort or a universal two-week walking clearance. |
| Dr. Kevin Debiparshad's LimbplastX Institute - undated page, read October 7, 2026 | The page describes participation in the February 2024 initial launch and a clinic-specific loading approach. [5] | Historical launch participation does not confirm current stock. Its stated 400 prior cases are STRYDE and PRECICE 2.2, not 400 MAX cases. |
| HSS Limb Lengthening and Complex Reconstruction Service - undated public feed, read October 7, 2026 | A team feed announces PRECICE MAX and improved mobility. [6] | No displayed post date, individual speaker, stock verification, or MAX case denominator; do not attribute it to a named surgeon. |
An attributed surgeon perspective
"The surgery itself is only one part of the journey," Dr. Dror Paley says in the institute's July 14, 2026 announcement. The source emphasizes selection, preparation, and support. This is a clinic statement, not independent medical review of this article. [4]
The institute's PMax page describes Paley's role in its design. That development involvement is relevant context when interpreting his assessment. This page does not infer undisclosed financial relationships or rank surgeons. No verified MAX-specific statement from Dr. Donghoon Lee was identified in the sources reviewed; his general lengthening animation is included in the beginner surgery guide. [7]
What does the FDA recall record say?
Recall Z-0500-2025 was initiated September 30, 2024 and posted November 21, 2024. It lists particular catalog numbers, lots, and UDIs, with 164 devices in commerce, and potential design, manufacturing, and validation-documentation issues. The customer action includes monitoring implanted patients and ceasing use of affected unimplanted stock. [2]
The record does not establish that every later MAX device is affected or unaffected. Nor does it instruct every recipient to seek automatic removal. Patients and clinicians need to reconcile the exact device identifiers with current manufacturer and regulator information. A newer clinic announcement does not, by itself, close the older recall. [2]
Where is MAX currently being used?
The clearest dated use report found here is Paley Institute's July 14, 2026 announcement of a procedure with the latest PMax. Its exclusivity wording describes that announcement's date; this review does not establish worldwide exclusivity in October. Undated clinic pages are weaker availability signals. No reliable global active-case count or country-by-country stock register was identified. [4] [5] [6]
Before making travel or payment arrangements, obtain the planned model, catalog number and lot or UDI; the current instruction revision; local regulatory status; and written confirmation that the clinic can supply that specific device. Also clarify rehabilitation, complication management, and later implant removal. The cost guide helps compare complete written quotes.
What remains uncertain about outcomes?
The FDA summary describes nonclinical performance testing. The manufacturer page reports bench testing, while the cited use reports are clinic statements. In the sources searched for this review, a MAX-specific long-term comparative outcome series was not identified. Studies of older PRECICE or STRYDE implants cannot establish MAX-specific superiority. Better mobility during one stage would not by itself prove better bone healing, long-term function, or fewer reoperations. [1] [3]
FAQ
Is PRECICE MAX FDA approved?
K232267 is a December 15, 2023 FDA 510(k) clearance based on substantial equivalence. Use the precise term clearance. It is not a personalized safety approval or proof of superior patient outcomes, and recall information must be checked separately. [1] [2]
Has the PRECICE MAX recall been resolved?
On October 7, 2026, FDA record Z-0500-2025 displayed "Open, Classified." It concerns listed product and lot identifiers. Check the live record and the exact proposed device rather than inferring status from the name MAX alone. [2]
Can I use a clinic's advertised full-weight-bearing timeline?
Treat it as that clinic's statement, not permission for your own implant or stage of healing. Obtain the current model-specific instructions and your team's individualized written restrictions before changing activity. [4] [5]
