K920929 is an FDA 510(k) clearance for the POLY INSERT 20 DEGREE. Classified as Prosthesis, Hip, Semi-constrained (metal Cemented Acetabular Component) (product code JDL), Class III - Premarket Approval.

Submitted by Dow Corning Wright (Arlington, US). The FDA issued a Cleared decision on May 5, 1993 after a review of 432 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3320 - 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. High regulatory complexity 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.
