Event Description

The literature article entitled ¿what are the complications, survival, and outcomes after revision to reverse shoulder arthroplasty in patients older than 80 years?¿, by eduard alentorn-geli, md, et al; published in the clinical orthopaedics and related research, july 11, 2017.The purpose of the article was to cover the questions of: what are the 90-day medical and surgical complications after revision to reverse shoulder arthroplasty (rsa) in patients older than 80 years? what are the 2-and 5-year survival rates after revision? was there an improvement in pain at rest or with activity range of motion (rom), and strength after revision surgery? between 2004 and 2013, 38 patients who were older than 80 years underwent revision surgery to a rsa.Of those, five were lost to follow-up before two years, and two had died within two years of revision surgery, leaving 31 for analysis of our survivorship, pain, rom, and strength endpoints at a minimum of two years or until revision surgery had occurred; all 38 patients were included for purposes of evaluating medical and surgical complications at 90 days.Medical complications occurred in three of 38 patients and surgical complications occurred in five of 38 patients.The 90-day mortality was 3% (one in 38 patients).The cumulative incidence of revision was 11% at two years and 16% at five years.Pain at rest or with activity improved from pre to post operation.The authors conclude that age should not be a reason to no consider revision surgery to rsa in patients older than 80 years.There were multiple prosthesis systems used, with only three of them being the delta reverse shoulder system (depuy).The article did not specify which prosthesis had complications.Medical complications included pneumonia in one patient, uti in one patient, and stroke in one patient.Surgical complications included glenoid loosening in three patients, deep infection with humeral component loosening in one patient, and component dissociation in one patient.Five patients required reoperations due to glenoid loosening (at two, nine and 15 months) after the index procedure; reoperations due to deep infection and component dissociation occurred at 35 months and at one month after the index procedure.There were no cases of scapular notching.Pain and active rom increased after operation.In this study, only one patient died during the first 90 days due to a stroke after one month.There were other deaths (9) reported in the article, however they occurred after at least 24 months and thereafter for various causes such as myocardial infarction, pneumonia and undetermined causes.
