Event Description

This report is being filed after the review of the following journal article: ellwein, a. Et al (2019), clinical evaluation of double-plate osteosynthesis for olecranon fractures: a retrospective case-control study, orthopaedics & traumatology: surgery & research, vol. 105 (8), pages 1601-1606 (germany). The aim of this retrospective study is to present the surgical technique using this novel double-plate implant and compare functional results (range of motion, patient related outcome scores), complications rates and revision surgeries to a common single, dorsal locking plate osteosynthesis. Between february 2011 to march 2015, a total of 47 patients (24 male and 23 female) with a mean age of 59 ± 19 years (range: 18¿93) underwent open reduction and internal fixation. Surgery was performed using a 3. 5 mm olecranon locking compression plate (lcp) (fa. Depuy synthes, umkirchen, germany) in 22 patients or olecranon low-profile double-plate from a competitor in 25 patients. The mean follow-up was 41 months (range: 25-61). The following complications were reported as follows: 4 patients had died due to unrelated causes. 8 patients underwent an overall nine revision surgeries. The remaining eight revision surgeries (36%) were implant removals and were performed on average 15 ± 4 months (range: 8¿21) after implantation. The implant was described as disturbing by all eight patients. All patients reported improvement after implant removal. 5 patients (23%) had an extension deficit of at least 10° compared with the contralateral elbow. 2 patients were unsatisfied with their result (9%); 1 because of a persisting moderate pain level (4 out of 10) and one because of severe limitations of elbow motion (extension/flexion: 0¿50¿90°). A 45-year-old patient reported persisting intraarticular friction. An additional ct-scan revealed an intraarticular screw, which was substituted with a shorter screw. This report is for an unknown synthes plate/screws constructs and unknown synthes screws. A copy of the literature article is being submitted with this medwatch. This report is for one (1) unknown plate/screws construct. This is report 1 of 2 for (b)(4).
