This report is being filed after the review of the following journal article: biermann, n.Et al.(2020), glenohumeral joint lavage does not affect clinical outcomes in open reduction and internal fixation of displaced intracapsular proximal humeral fractures: a prospective, randomized, double-blinded trial, journal of shoulder and elbow surgery, vol.29, pages 1758-1764, (germany).The aim of this trial was to determine the effect of intraoperative glenohumeral joint lavage on rom and functional outcomes after open reduction and internal fixation of displaced intracapsular proximal humeral fractures.Between january 2016 and april 2018, 72 patients (mean age: 65.2 +/ 16.3 years) with a displaced intracapsular proximal humeral fracture were treated by open reduction and internal fixation using an anatomically precontoured locking plate (philos; depuy synthes gmbh, oberdorf, switzerland).Patients were randomized to either locked plating followed by intraoperatively performed glenohumeral joint lavage (group l, n = 36; 19 females and 12 males) or locked plating without the lavage (group nl, n = 36; 22 females and 9 males).The postoperative study protocol included a prospective examination of functional outcomes at 6 weeks, 3 months 6 months, and 12 months of follow-up.The following complications were reported as follows: 3 patients deceased within the 1-year study period due to causes unrelated to the fracture treatment 3 patients had avascular necrosis.1 patient had secondary displacement.1 patient had adhesive capsulitis.1 patient had secondary displacement with articular screw perforation.This report is for an unknown synthes philos construct.It captures the reported avascular necrosis, secondary displacement, adhesive capsulitis.This is report 1 of 2 for (b)(4).
