Examining the Effects of Modifiable Risk Factors on Postoperative Outcomes after Total Shoulder Arthroplasty

Background The reverse total shoulder arthroplasty has become the most common method of arthroplasty of the shoulder. The complication of acromial or scapular stress fracture deserves consideration to describe incidence and determine whether prosthetic design or patient factors act as risk factors. Methods A systematic review of the literature was performed including the EMBASE, Medline and the Cochrane Library in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results The search returned 565 articles. After exclusion, 25 papers remained. In total, 208 fractures were reported in the literature, with an overall incidence of 5% and stress fractures were more common than post-traumatic ones; 24 fractures underwent osteosynthesis and there were nine revision arthroplasty surgeries. Outcomes worsened after fracture – whether treated with surgery or not. In patients with scapular base fractures, there was an improvement in functional outcome scores after surgery. Heterogeneous reporting of the risk factors prior to fractures, treatment methods and outcomes made recommendations weak. Discussion Acromial stress fracture after reverse total shoulder arthroplasty occurs relatively commonly but is poorly reported in the literature. It is unclear whether immobilisation, fixation or revision arthroplasty is the best treatment, although fixation may offer a better outcome. In future, reports should aim for greater consistency to allow a better understanding of this condition.

Humerus Fractures

Introduction There has been a reported increase in the number of proximal humerus fractures being surgically managed. In an attempt to manage increasing costs associated with increasing volume, there is a need for identification of factors associated with discharge destinations. Methods The 2012–2016 American College of Surgeons—National Surgical Quality Improvement Program database was queried using Current Procedural Terminology codes for open reduction internal fixation, hemiarthroplasty, and total shoulder arthroplasty being performed for proximal humerus fractures. Results Five hundred and seventy-six (21.5%) patients had nonhome discharge disposition. Following adjusted analysis, age > 65 years (p < 0.001), partially dependent functional health status prior to surgery(p = 0.027), inpatient surgery (p = 0.010), American Society of Anesthesiologists (ASA) grade>II (p < 0.001), transfer from nursing home/chronic care facility (p < 0.001), undergoing a total shoulder arthroplasty versus open reduction internal fixation (p = 0.012), length of stay > 2 days (p < 0.001), and the occurrence of any predischarge complication (p < 0.001) were significant predictors associated with a nonhome discharge disposition. Conclusion The study identifies significant risk factors associated with a nonhome discharge and assesses clinical impact of nonhome discharge destination on postdischarge outcomes. Providers can utilize these data to preoperatively risk stratify those at an increased risk of a nonhome discharge, counsel patients on discharge expectations, and tailor a more appropriate postoperative course of care.

Background Despite increasing rates of revision total shoulder arthroplasty (RTSA), there is a paucity of literature on optimizing perioperative outcomes. The purposes of this study were to identify risk factors for unplanned readmission and perioperative complications following RTSA, risk-stratify patients based on these risk factors, and assess timing of complications. Methods Bivariate and multivariate analyses of risk factors were assessed on RTSA patients from the ACS-NSQIP database from 2011 to 2015. Patients were risk-stratified and timing of severe adverse events and cause of readmission were evaluated. Results Of 809 RTSA patients, 61 suffered a perioperative complication or readmission within 30 days of discharge. Multivariate analysis identified operative time, BMI > 40, infection etiology, high white blood cell count, and low hematocrit as significant independent risk factors for 30-day complications or readmission after RTSA (p ≤ 0.05). Having at least one significant risk factor was associated with 2.71 times risk of complication or readmission within 15 days compared to having no risk factors (p < 0.001). The majority of unplanned readmission, return to the operating room, open/deep wound infection, and sepsis/septic shock occurred within two weeks of RTSA. Discussion Patients at high risk of complications and readmission after RTSA should be identified and optimized preoperatively to improve outcomes and lower costs.
