This report is being filed after the review of a clinical evaluation report (cer) from a related research activity database (ddra) for 894 patients undergoing a distal tibia repair using the synthes dtp system.Of these, 722 patients met the 12-month hospital enrollment criterion.One patient was removed due to unknown sex.Patient age ranged from 9 to 89 years, with a mean (sd) of 47 (16.4) years and a median of 47 years.More than half of the patients implanted with the synthes dtp system were male.Patients were identified in the premier healthcare database (phd) between january 1, 2004, and march 31, 2019.In 721 patients (313 females, 408 males) included in the study, 509 patients had at least one locking compression plate (lcp) plate and 189 patients had at least one variable angle locking compression plate (va-lcp) plate.Cumulative incidence rates for subsequent surgery, nonunion, and malunion within 12 months post-surgery based on icd-9/10 procedure codes and malunion and nonunion were based on icd-9/10 diagnosis codes.(n=21) subsequent surgery, at 90 days post-surgery lcp, cumulative (n=2) cumulative incidence of malunion at 90 days s post-surgery was for patients with lcp plates.(n=57) subsequent surgery, at 12 months post-surgery lcp, cumulative (n=44) cumulative incidence of nonunion at 12 months post-surgery was for patients with lcp plates.(n=6) cumulative incidence of malunion at 12 months post-surgery was for patients with lcp plates.(n=10) subsequent surgery, at 90 days post-surgery va-lcp, cumulative (n=23) subsequent surgery, at 12 months post-surgery va-lcp, cumulative (n=13) cumulative incidence of nonunion at 12 months post-surgery was) for patients with va-lcp plates.This is for depuy synthes distal tibial plates (lcp and va-lcp).This is report 3 of 4 for (b)(4).
