How long does FDA review take for MNH?

The median FDA review time for MNH is 90 days, measured across the 309 most recent decisions with both a received date and a decision date.

Review time here is decision date minus date received, as published by FDA. It is elapsed calendar time, not FDA review days — the two differ whenever the agency stops the clock for an additional information request.

Are there recalls in MNH?

openFDA lists 15 recall records against product code MNH. A recall record covers one firm's corrective action and may span many device lots.

  • Z-1884-2017TerminatedXTANT MEDICAL INC

    The material type on the label may incorrectly state Ti6Al-4V ELI. The rods are composed of Cobalt Chromium.

  • Z-0883-2017TerminatedAmendia, Inc dba Spinal Elements

    The rods are packaged in packages with unacceptable seals. In some cases, the integrity of the seal is compromised by channels or voids.

  • Z-1823-2015TerminatedX Spine Systems Inc

    The Continuous Radius Rod should measure 50mm in length but actually measures 45mm in length.

  • Z-1512-2015TerminatedX Spine Systems Inc

    One lot of instruments have etched on the Yoke of the Pedicle Screw a laser marking size of 7.5 x 55mm instead of 5.5 x 55mm as described on the product label.

  • Z-0938-2013TerminatedSynthes USA HQ, Inc.

    Lot number 7542279, of the 45 mm Click 'X Pedicle Screw (Part number 487.072), was incorrectly etched as "Click 'X Pedicle Screw 05.2 L40 TAN violet" although the actual length of the screw is 45 mm.

Showing the 5 most recently initiated of 15. Recall class comes from openFDA's enforcement endpoint, which does not carry every recall — where it is missing, none is shown rather than guessed. Status is FDA's own wording; a terminated recall is a closed one, and the total spans the code's whole history, not just what is open today.

How many adverse events are reported for MNH?

MAUDE holds 514 adverse-event reports naming product code MNH, 49 of them received in the last 12 months.

MAUDE reports are submitted by manufacturers, importers, user facilities and the public. They are unverified, and a report is not proof that the device caused the event.

Is adverse-event reporting in MNH unusual?

Every month with enough history behind it falls inside MNH's own expected range. Nothing here is unusual for this code.

21 months do not have a full, unbroken year of history before them, so no expected range is shown for those. Insufficient history is reported as insufficient rather than as zero: an empty baseline would turn a gap in our data into a spike. Method: ewma_alpha_0.3_sd_2 corpus_adjusted. Counts are divided by the corpus-wide volume for that month before comparison, so a rise across all of MAUDE is not reported as a rise in MNH.

What are the predicate devices in MNH?

FDA publishes no machine-readable predicate field, so no predicate chain is recorded for this code yet.

A predicate chain matters because a device inherits the safety history of what it was compared to. FDA publishes the chain only inside each 510(k) summary PDF, never as data — so where we have edges, they are read from those documents, and where we do not, we say so instead of showing an empty list.
