K933108 is an FDA 510(k) clearance for the TITAN TROCHANTERO-DIAHYSEAL TOTAL HIP PROSTHESIS. Classified as Prosthesis, Hip, Semi-constrained, Metal/ceramic/polymer, Cemented Or Non-porous, Uncemented (product code LZO), Class II - Special Controls.

Submitted by Landos, Inc. (Malvern, US). The FDA issued a Cleared decision on September 12, 1994 after a review of 444 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3353 - 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.
