Submitted by Smith & Nephew Richards, Inc. (Memphis, US). The FDA issued a Cleared decision on April 2, 1993 after a review of 374 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3358 - 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.
