K912837 is an FDA 510(k) clearance for the MCAFEE SPINAL SYSTEM FOR POSTERIOR APPLICATIONS. Classified as Appliance, Fixation, Spinal Interlaminal (product code KWP), Class II - Special Controls.

Submitted by Kirschner Medical Corp. (Timonium, US). The FDA issued a Cleared decision on August 26, 1992 after a review of 427 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 888.3050 - 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.
