FDA 510(k) Recap: Knees, Hips, Shoulders, Wrists and Elbow Joints

Of 44 products that received FDA 510(k) clearance under the orthopedic panel in May, half were spine devices and a little over a quarter were for joint replacement (27%). (The rest were trauma, 7 clearances; sports medicine, 2 and orthobiologics, 1.)

Despite the fact that spine devices always seem to garner the most clearances in any given month, joint replacement is the bread and butter for most of the diversified companies. This month, let’s focus on these products that rebuild knees, hips and extremities. Two are from companies receiving their first orthopedic-related clearance; most are from folks that you know.
