(report 4 of 8).In the article " radial head replacement for acute complex elbow instability: a long-term comparative cohort study of two implant designs" by sanchez, b.D.; et al, the authors performed a study to compare the long-term clinical and radiological 3 outcomes of two radial head replacement (rhr) designs in the context of complex 4 acute elbow instability.Ninety-five patients with an average age of 54 years (range, 21- 12 87 years) underwent an acute radial head replacement (rhr) (46 press-fit acumed anatomic radial head and 49 loose-fit 13 evolve metallic spacer) and were prospectively followed for an average of 61 months 14 (range, 24 to 157 months).Eight patients with an anatomic rhr (3 with overstuffing, 1 for stiffness, 2 with loose implants, and 2 with proximal forearm pain) and 1 patient with a spacer (with stiffness) required implant removal- the spacer was from a different manufacturer.This report is related to report numbers 3025141-2023-00443, 3025141-2023-00444, 3025141-2023-00445, 3025141-2023-00447, 3025141-2023-00448, 3025141-2023-00449 and 3025141-2023-00450.
