K171904 is an FDA 510(k) clearance for the Tandry Locking Plate System. Classified as Plate, Fixation, Bone within the HRS classification (a category comprising bone fixation plates and orthopedic hardware), Class II - Special Controls.

Submitted by Microware Precision Co., Ltd. (Taichung, TW). The FDA issued a Cleared decision on September 18, 2018 after a review of 449 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3030 - the FDA orthopedic device regulatory framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Orthopedic submissions.
