K163081 is an FDA 510(k) clearance for the 40-42mm BiPolar Head and 22mm Femoral Head. Classified as Prosthesis, Hip, Hemi-, Femoral, Metal/polymer, Cemented Or Uncemented (product code KWY), Class II - Special Controls.

Submitted by Signature Orthopaedics Pty, Ltd. (Lane Cove West, AU). The FDA issued a Cleared decision on January 29, 2018 after a review of 452 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3390 - 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.
