Device report from synthes reports an event in south korea as follows: this report is being filed after the review of the following journal article: park s-g, seok h-g (2022) bi columnar locking plate fixation through a combined medial and lateral approach for the treatment of low transcondylar fractures of the distal humerus in the elderly, bmc musculoskeletal disorders, volume 23, page 764, https://doi.Org/10.1186/s12891-022-05594-1 (south korea).The purpose of this study was to present the outcomes of bi-columnar internal fixation through a combined medial and lateral approach for the treatment of low transcondylar fractures of the distal humerus in the elderly.Between may 2017 and april 2020, 46 patients diagnosed with distal humeral fractures were included in the study.There were 3 males and 13 female patients, and the mean age of the patients was 81 years (range, 65¿91 years).During the procedure, a short locking compression plate the unknown synthes 2.7 mm variable angle lcp elbow system was used on the medial column and a long locking compression plate unknown synthes 3.5 mm variable angle lcp elbow system was used on the lateral column.Postoperatively, the elbow was placed in a bulky noncompressive dressing with a posterior plaster slab to keep the elbow flexed between 40 degrees and 50 degrees.Active-assisted and passive motion was encouraged 3 weeks after the surgical procedure.At 6 weeks, the patients were encouraged to regain rom of the elbow, and gentle daily activities were permitted.At 3 months, usual activity was allowed.Complications were reported as follows: patient 4, an 81-year-old male had screw migration with loss of reduction in varus during the early months after fixation.However, the fractures eventually healed without additional surgery.Patient 6, a 65-year-old female had stiffness or approximately 80 degrees of motion restriction (105 degrees of flexion, 35 degrees of extension) at 6 months after surgery.She regained a rom of about 110 degrees after removal of the instrument without the release of contracture.Patients 10, an 87-year-old female had medial skin necrosis over the ulnar plate that was identified 6 months after surgery.Since the fracture was healed, the hardware was removed, and the skin was debrided and re-sutured.A copy of the clinical evaluation form is being submitted with this regulatory report.This report involves one unk - screws: locking: variable angle.This is report 1 of 4 for (b)(4).
