The role of body mass index in survivorship and clinical outcomes in total shoulder arthroplasty. J Shoulder Elbow Surg 2024; 33:1980-1989. [PMID: 38423249 DOI: 10.1016/j.jse.2024.01.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 01/06/2024] [Accepted: 01/08/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Increased body mass index (BMI) is a potential risk factor for poorer outcomes and complications. However, the influence of BMI on the long-term outcomes of anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) remains to be fully elucidated. METHODS Institutional records were queried to identify patients who underwent primary total shoulder arthroplasty (TSA) between 2009 and 2020 with a minimum of 2 years of clinical follow-up. Retrospective review was performed to collect demographic characteristics; comorbidity status; and range-of-motion and strength measurements in forward elevation, external rotation, and internal rotation. Patients were contacted by telephone to provide patient-reported outcomes (PROs). Patients were stratified into 3 cohorts by BMI: underweight or normal weight (U/NW, BMI ≤25 kg/m2), overweight (OW, BMI >25 to ≤30 kg/m2), and obese (BMI >30 kg/m2). RESULTS Among 466 TSA patients, 245 underwent aTSA whereas 221 underwent rTSA. In the aTSA cohort, 40 patients were classified as U/NW; 72, as OW; and 133, as obese. Comparatively, the rTSA cohort was composed of 33 U/NW, 79 OW, and 209 obese patients. Patients in the aTSA and rTSA cohorts had an average follow-up period of 5.8 ± 3.2 years and 4.5 ± 2.3 years, respectively. No differences in age at surgery were found in the aTSA group (U/NW vs. obese, 65.2 ± 7.9 years vs. 61.9 ± 8.9 years; P = .133); however, in the rTSA cohort, BMI was found to be inversely related to age at surgery (U/NW vs. obese, 72.4 ± 8.8 years vs. 65.7 ± 8.3 years; P < .001). Across all BMI cohorts, patients saw great improvements in range of motion and strength. Postoperative PROs after TSA did not vary by BMI in terms of Single Assessment Numeric Evaluation, Simple Shoulder Test, visual analog scale pain, and American Shoulder and Elbow Surgeons scores. There was no significant difference in survival rates at 10-year follow-up in the aTSA cohort (U/NW vs. obese, 95.8% vs. 93.2%; P = .753) or rTSA cohort (U/NW vs. obese, 94.7% vs. 94.5%; P = .791). CONCLUSION With dramatic improvements in range of motion, minimal differences in PROs, and high rates of implant survival, TSA is a safe and effective treatment option for all patients, including overweight and obese patients.

Abstract
PURPOSE OF REVIEW Reverse shoulder arthroplasty (rTSA) is a commonly performed procedure to treat degenerative conditions of the shoulder. With its growing utilization, techniques to reliably diagnose and treat prosthetic joint infection (PJI) have become increasingly important. In this review we outline the current research and prevention methods of prosthetic joint infection in rTSA. This includes preoperative considerations, intraoperative, and postoperative treatment algorithms. RECENT FINDINGS There is currently no established standardized protocol for preoperative infection prevention or post operative management. However, recent studies have identified risk factors for infection, as well as successful prevention techniques that can be implemented to minimize infection risk. Although there is no standardized protocol currently utilized to diagnose and treat shoulder PJI, we outline a potential set of preventative measures and postoperative management strategies that clinicians can use to properly diagnose and treat patients with this difficult condition.

Abstract
Background The role of obesity as an independent risk factor for increased complications following reverse shoulder arthroplasty (RSA) continues to generate debate. While no standardized body mass index (BMI) cutoff values for shoulder arthroplasty exist, many surgeons are concerned about the potential for poor outcomes and decreased range of motion (ROM) in patients with a high BMI. The purpose of this study was to compare functional outcomes in obese and nonobese patients preoperatively and at short-term follow-up after RSA. Methods A retrospective review was performed of a prospectively maintained, multicenter database of primary RSAs performed by 14 surgeons between 2015 and 2019 with minimum 2-year follow-up. A total of 245 patients met the study criteria, including 111 obese (BMI >30) and 134 nonobese (BMI <30) patients. Patient-reported outcomes (PROs) as well as ROM measurements were compared between the 2 groups. Results At baseline, obese patients had significantly lower American Shoulder and Elbow Surgeons (36.6 vs. 42.0, P = .014), Western Ontario Osteoarthritis of the Shoulder scores (33.1 vs. 37.8, P = .043), external rotation at 90° (19° vs. 28°, P = .007), internal rotation (IR) spinal level (L5 vs. L4, P = .002), and belly press strength (P = .003) compared to the nonobese cohort. There were no statistical differences in 2-year outcomes (PROs, ROM, and strength) other than a worse IR (spinal level) in the low BMI group (L4 vs. L3, P = .002). In linear regression analyses controlling for confounding variables, increasing BMI was negatively correlated with preoperative external rotation (B = -0.591, P = .034) and preoperative IR spinal level (B = 0.089, P = .002). Increasing BMI was not correlated with postoperative external rotation at 90° (B = 0.189, P = .490) but was associated with worse postoperative IR by spinal level (B = 0.066, P = .043). Conclusions Obese patients have greater restrictions in external and internal rotation as well as American Shoulder and Elbow Surgeons and Western Ontario Osteoarthritis of the Shoulder scores at baseline prior to RSA. However, there are no major differences in postoperative PROs or ROM measurements between obese and nonobese patients apart from a worse active IR by spinal level in the obese group (L4 vs. L3, P = .002). This study suggests that an RSA procedure does not need to be restricted solely based on BMI.

[PMID: 38041138 PMCID: PMC10693107 DOI: 10.1186/s42836-023-00214-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 09/15/2023] [Indexed: 12/03/2023] Open
Abstract
INTRODUCTION Reverse shoulder arthroplasty (RSA) is considered one of the greatest technological innovations in shoulder reconstruction surgery, as evidenced by the fact its growth rate of usage is greatest among all shoulder arthroplasties. However, like all arthroplasties, a post-surgical complication often arises. One of these complications, periprosthetic dislocation (PPD), requires revision and poses, therefore, a burden on both patients and healthcare providers. While PPD is understood to be a complication of RSA, it is unclear to what extent certain risk factors and co-morbidities predispose patients to post-RSA PPD. The purpose of this study was to identify and evaluate the impact of specific risk factors and co-morbidities that contribute to the development of PPD following RSA. METHODS In this retrospective study, we used the Nationwide Inpatient Sample (NIS) database from 2016-2019 to analyze the prevalence and impact of various risk factors and co-morbidities on the incidence of PPD following RSA. A univariate and subsequent multivariate logistic regression model was made to provide a descriptive association between variables that impact the rates of PPD after RSA. RESULTS The NIS database identified 59,925 patients, 1,000 of whom experienced a PPD while the remaining 58,825 were placed in the non-PPD group (controls). The PPD group consisted predominantly of females (53.10%) and Caucasians (86.30%). There was a higher incidence of tobacco-related disorders (P = 0.003), obesity (P < 0.001), morbid obesity (P < 0.001), liver cirrhosis (P < 0.001), and Parkinson's disease (PD) (P < 0.001) in PPD patients compared to controls. Young patients had a 1.89-fold increased odds (OR: 1.89, 95% CI [1.58, 2.26], P < 0.001), patients with tobacco-related disorders had decreased odds (OR: 0.80, 95% CI [0.67, 0.97], P = 0.02), morbidly obese patients had 1.50 times the odds (OR: 1.50, 95% CI [1.14, 1.97]), liver cirrhosis patients had 2.67-fold increased odds (OR: 2.67, 95% CI [1.55, 4.60], P < 0.001), and Parkinson's disease patients had 2.66 times the odds (OR: 2.66, 95% CI [1.78, 3.96], P < 0.001) to develop PPD following RSA compared to patients who did not have the corresponding condition. CONCLUSIONS Patients with specific risk factors and co-morbidities are predisposed to developing PPD after RSA. Risk factors that were found to be associated with a higher incidence of PPD are gender (female), race (Caucasian), and age (young patients). Analysis revealed the history of tobacco-related disorder, obesity, morbid obesity, liver cirrhosis, and Parkinson's disease increased the odds of developing PPD following RSA. These findings can inform both healthcare providers and patients to improve RSA surgical outcomes and tailor post-surgery recovery programs to fit the patient's needs.

Reference values and influencing factors of the glenohumeral subluxation index: a study on 3004 participants. J Shoulder Elbow Surg 2023; 32:2533-2540. [PMID: 37290636 DOI: 10.1016/j.jse.2023.04.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 04/17/2023] [Accepted: 04/24/2023] [Indexed: 06/10/2023]
Abstract
BACKGROUND The primary objective of this study was to examine the glenohumeral subluxation index (GHSI) in a large general population cohort and to define reference values. Glenohumeral subluxation is important in the development and prediction of pathological states of the shoulder joint and in total shoulder arthroplasty. Therefore, another objective was to examine the influence of age, sex, body mass index, and body height and weight on GHSI. METHODS GHSI according to Walch was measured on bilateral magnetic resonance imaging of 3004 participants of the Study of Health in Pomerania (SHIP, aged 21-90 years). SHIP drew a sample of the adult general population of Pomerania (Northeastern Germany). Reference values for GHSI were assessed by quantile regression models. Associations of sex, age, and anthropometric markers with the GHSI were calculated by linear regression models. RESULTS A reference range between 42% and 55% for men with a mean of 49% ± 4% was defined, while the upper reference limit for women was 1% higher (mean, 50% ± 4%). Age was inversely associated with the GHSI in males (P < 0.001), while no significant association in females was observed (P = .625). Body weight and body mass index were positively associated (P < .001) without effect modification by sex. Heavy mechanical oscillations on the upper extremity showed no significant association with GHSI (P = .268). CONCLUSION The reference values for GHSI were expanded to a range of 42%-57% on magnetic resonance imaging. Several associations between GHSI and anthropometric properties are present. According to these associations, adjusted formulas are provided to enable individual, patient-specific diagnostics and therapy. Nevertheless, the clinical picture cannot be neglected.

Abstract
PURPOSE The oculofacial plastic surgeon will more frequently encounter challenges related to overweight and obese patients as the incidence rises. There is a paucity of data in the oculofacial plastic surgical literature regarding this topic. The goal of this review is to detail the role obesity plays in the perioperative course and the considerations for a surgeon treating this patient population. METHODS The authors conducted a computerized search using PubMed, Embase, and Google Scholar. The search terms used were "(obesity OR overweight) AND surgery," "(obesity OR overweight) AND oculoplastic," "(obesity OR overweight) AND oculofacial," "(obesity OR overweight) AND 'facial plastic surgery', " "(obesity OR overweight) AND 'bariatric surgery', " "(obesity OR overweight) AND (pre-operative OR post-operative OR intraoperative," " (obesity OR overweight) AND complications," "(obesity OR overweight) AND (facial plastic surgery) AND complications)," "(obesity OR overweight) AND eyelid," "(obesity OR overweight) AND (nasolacrimal OR 'nasolacrimal duct')," "(obesity OR overweight) AND IIH," "(obesity OR overweight) AND exophthalmos." RESULTS A total of 127 articles, published from 1952 to 2022 in the English language or with English translations were included. Articles published earlier than 2000 were cited for foundational knowledge. References cited in the identified articles were also used to gather further data for the review. CONCLUSIONS Overweight and obese patients pose specific challenges that the oculofacial plastic surgeon should be aware of to better optimize patient outcomes. Multiple comorbidities, poor wound healing, and nutritional deficits all contribute to the complications experienced in this patient population. Further investigation on overweight and obese patients is needed.

Abstract
Background A recently proposed risk factor for periprosthetic joint infections (PJI) in men is benign prostatic hyperplasia (BPH). The objective was to explore the association of BPH on 1) 90-day complications, 2) length of stay (LOS), 3) readmission rates, and 4) healthcare expenditures following total shoulder arthroplasty (TSA). Methods A retrospective query was performed using a nationwide claims database from January 2005 to March 2014 for male patients undergoing primary TSA. The study cohort included 5067 patients with BPH while 50,720 patients served as the comparison cohort. Logistic regression determined the association of BPH on complications and readmissions. A p value less than 0.001 was significant. Results Patients with BPH had higher incidence and odds (36.8 vs. 6.2%; OR: 2.73, p < 0.0001) of all ninety-day medical complications including PJIs (0.49 vs. 0.32%; OR: 1.54, p < 0.001). BPH patients had longer in-hospital LOS (3- vs. 2-days, p < 0.0001). Study group patients had higher 90-day episode of care reimbursements ($13,653 vs. $12,688), p < 0.0001). Conclusions BPH is associated with increased complications and healthcare expenditures following total shoulder arthroplasty. The investigation can be used to educate BPH patients of the possible adverse events which may occur within ninety-days following primary TSA for the treatment of glenohumeral osteoarthritis.

Abstract
BACKGROUND The proportion of patients undergoing total shoulder arthroplasty (TSA) with obesity continues to grow every year in the United States. Although comorbid obesity is common among TSA patients, the relationship of obesity on medical and surgical complications remains debated. The goal of this study was to evaluate a national database for postoperative medical and surgical complications in patients undergoing TSA with comorbid obesity. METHODS Patients undergoing anatomic and reverse TSA were studied in the PearlDiver database. Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes were used to compare patients with and without preoperative obesity who underwent TSA, and they were stratified based on body mass index (BMI) into nonobese, obese, morbidly obese, and superobese. A matched comparison was performed at a 1:1 ratio based on age, sex, diabetes, smoking, tobacco use, and Charlson Comorbidity Index. RESULTS From 2010 to 2020, a total of 113,634 patients undergoing anatomic or reverse TSA were identified in a national database. During this time, the percentage of TSA patients with obesity increased every year. Matched cohort analysis demonstrated higher odds of readmission, deep vein thrombosis and pulmonary embolism, superficial infection, and prosthetic joint infection at 90 days postoperatively in the obesity group. There were no increased odds of mechanical complications or revision surgery at 2 years in the obesity group when matched to nonobese patients with similar comorbidities. CONCLUSION The number of patients undergoing TSA with obesity is rising. Medical complications and infection after TSA are greater in obese patients even when matching for medical comorbidities, age, and sex, and rates of complication increase as BMI increases. Obesity is not an independent risk factor for mechanical surgical complications and revision surgery, and the relatively higher rates are likely due to an increased burden of other comorbidities. Surgeons should counsel obese patients appropriately regarding their perioperative risk of medical complication, but they should not expect higher rates of mechanical complication or revision surgery at 2-year follow-up when compared to a matched control group with similar comorbidities.

Abstract
Background Reverse shoulder arthroplasty (RSA) has become commonly used to treat glenohumeral osteoarthritis (GHOA), of which complications such as peri-prosthetic joint infections (PJIs) may develop. The objective of this study was to compare patient demographics of those who did and did not develop PJIs within 2 years after primary RSA for GHOA and identify risk factors for this sequela. Methods A nationwide database was queried from 2005 to 2014 for Medicare patients treated with primary RSA (International Classification of Disease (ICD-9) procedural code 81.88) for GHOA. Patients who developed PJIs within 2-years of primary RSA defined the study group, whereas those who were devoid of infections represented the comparison group. Our study consisted of 51,824 patients, of which 879 (1.69%) developed a PJI. Patient demographics comprising the Elixhauser comorbidity index (ECI) were compared using Chi-Square analyses. Multivariable logistic regression models were used to compute the odds-ratios (OR) of patient-specific factors associated with acquiring a PJI within 2 years after RSA. P values less than 0.002 were significant. Results Patients developing a PJI had higher mean ECI (8 vs. 6; p < 0.0001). The greatest risk factors for developing PJIs within 2-years following RSA were male sex (OR: 2.10, 95%CI: 1.81-2.43, p < 0.0001), pathologic weight loss (OR: 1.78, 95%CI: 1.45-2.17, p < 0.0001), iron deficiency anemia (OR: 1.75, 95%CI: 1.49-2.06, p < 0.0001), morbid obesity (OR: 1.52, 95%CI: 1.21-1.88, p = 0.0001), rheumatoid arthritis (OR: 1.32, 95%CI: 1.13-1.54, p = 0.0003), arrhythmias (OR: 1.26, 95%CI 1.09-1.46, p = 0.001), and depressive disorders (OR: 1.23, 95%CI 1.06-1.43, p = 0.001). Conclusions The greatest risk factors for PJIs within 2 years of primary RSA included male sex; additional modifiable risk factors included iron deficiency anemia, pathologic weight loss, and obesity. Preoperative screening can help to identify modifiable risk factors and alter management for high-risk patients to potentially minimize PJIs.

Abstract
PURPOSE Joint arthroplasty has become increasingly more common in the United States, and it is important to examine the patient-based risk factors and surgical variables associated with hospital readmissions. The purpose of this study was to identify stratified rates and risk factors for readmission after upper extremity (shoulder, elbow, and wrist) and lower extremity (hip, knee, and ankle) arthroplasty. METHODS All patients undergoing upper and lower extremity arthroplasty from 2008-2018 were identified using the National Surgical Quality Improvement Program dataset. Patient demographics, medical comorbidities and surgical characteristics were examined utilizing uni- and multi-variate analysis for significant predictors of 30-days hospital readmission. RESULTS A total of 523,523 lower and 25,215 upper extremity arthroplasty patients were included in this study. A number of 22,183 (4.2%) lower and 1072 (4.4%) upper extremity arthroplasty patients were readmitted within 30 days of discharge. Significant risk factors for 30-days readmission after lower extremity arthroplasty included age, Body Mass Index (BMI), operative time, dependent functional status, American Society of Anesthesiologists (ASA) score ≥3, increased length of stay, and various medical comorbidities such as diabetes, tobacco dependency, and chronic obstructive pulmonary disease (COPD). An overweight BMI was associated with a lower odds of 30-days readmission when compared to a normal BMI for lower extremity arthroplasty. Analysis for upper extremity arthroplasty revealed similar findings of significant risk factors for 30-days hospital readmission, although diabetes mellitus was not found to be a significant risk factor. CONCLUSION Nearly one in 25 patients undergoing upper and lower extremity arthroplasty experiences hospital readmission within 30-days of index surgery. There are several modifiable risk factors for 30-days hospital readmission shared by both lower and upper extremity arthroplasty, including tobacco smoking, COPD, and hypertension. Optimization of these medical comorbidities may mitigate the risk short-term readmission following joint arthroplasty procedures and improve overall cost effectiveness of perioperative surgical care.

Revision Rates and Associated Risk Factors after Shoulder Arthroplasty. J Clin Med 2022; 11:jcm11247256. [PMID: 36555873 PMCID: PMC9786091 DOI: 10.3390/jcm11247256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/01/2022] [Accepted: 12/05/2022] [Indexed: 12/12/2022] Open
Abstract
This study aims at answering the following questions (1) How high is the revision rate after osteoarthritis-, and rotator cuff-related compared to proximal humerus fracture (PHF)-related shoulder arthroplasty? (2) What are the associated risk factors for a revision after shoulder arthroplasty? Shoulder arthroplasty procedures occurring between 1 January 2009 and 31 December 2019 were identified from the Medicare database. First, revision rates for PHF patients and age- and sex-matched non-fracture patients, grouped into osteoarthritis-related and rotator cuff-related arthroplasty, were compared. Second, revision rates between total shoulder arthroplasty and hemiarthroplasty after PHF were compared. Semiparametric Cox regression was applied, incorporating 23 demographic, clinical, and socioeconomic covariates, to investigate risk factors for revision surgery. Between the considered time period from 2009 through 2019, a total number of 47,979 PHFs was identified. A shoulder arthroplasty procedure was performed in n = 2639 (5.5%, 95%CI: 4.8-6.1) of the cases. The five-year survivorship of the implant was 96.3 (95%CI: 93.8-97.9) after hemiarthroplasty and 96.1% (05%CI: 94.2-97.3) after total shoulder arthroplasty. To compare the revision rates, n = 14,775 patients with osteoarthritis and n = 4268 patients with rotator cuff arthropathy, who received a shoulder arthroplasty, served as a non-fracture control group. Patients receiving a rotator cuff-related arthroplasty were more likely to require a revision compared to patients treated for osteoarthritis (HR: 1.27, 95%CI: 1.04-1.44, p = 0.018). Identified significant risk factors for revision surgery after shoulder arthroplasty included age ≤ 75 years, male sex, and osteoporosis. High implant survival was found for hemiarthroplasty and total shoulder arthroplasty for the treatment of PHF in elderly patients. The risk of revision surgery was elevated in patients receiving a rotator cuff-related arthroplasty as well as in patients with osteoporosis, male patients and patients older than 75 years.

J Shoulder Elbow Surg 2022; 32:991-1000. [PMID: 36464204 DOI: 10.1016/j.jse.2022.10.032] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 10/12/2022] [Accepted: 10/24/2022] [Indexed: 12/03/2022]
Abstract
BACKGROUND As of 2018, upwards of 42% of the US adult population was considered obese based on body mass index (BMI) scales. With the annual number of total joint replacements increasing, this study aimed to evaluate the impact BMI has on anatomic total shoulder arthroplasty (aTSA) outcomes. METHODS This was a retrospective analysis of 128 shoulders requiring primary aTSA. Patients were stratified into 3 cohorts based on their BMI at surgery: underweight/normal weight (U/NW; BMI ≤25.0), overweight (25.0 < BMI ≤ 30.0), and obese (BMI >30.0). BMI was separately analyzed as a continuous variable. Clinical endpoints were range of motion scores, including forward elevation, external rotation, and internal rotation, and patient-reported outcomes, including visual analog scale (VAS) scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, and the Simple Shoulder Test (SST). Survivorship curves were calculated using Kaplan-Meier analysis. RESULTS Forty-four, 50, and 34 patient shoulders were in the U/NW, overweight, and obese cohorts, respectively. The mean follow-up time was 11.4 years. The U/NW cohort had more females (73%) compared with the overweight (34%; P = .0030) and obese (35%; P = .0015) groups; no differences were seen in revision rates. BMI was negatively correlated with age at surgery (r = -0.19, P = .014); it was not correlated with any of the 6 postoperative clinical endpoints. All 3 cohorts saw significant improvements in forward elevation, external rotation, internal rotation and VAS, ASES, and SST scores when compared preoperatively to postoperatively (P < .001). There were no significant differences between the 3 cohorts with respect to postoperative range of motion. Postoperative ASES scores were higher for the overweight cohort (82.6 ± 18.6) compared with both the U/NW (63.0 ± 25.1) and obese cohorts (70.5 ± 26.8) (P < .001). The overweight cohort also had higher SST (P = .0012) postoperative scores compared with the U/NW and obese cohorts; VAS scores were comparable between groups (P = .12). The nonobese (BMI <30) group (n = 94) showed 5-, 10-, and 15-year implant survival of 98.9%, 94.9%, and 83.9%, respectively compared to 97.1%, 93.7%, and 87.0% in the obese (BMI ≥30) group (n = 34). The log rank test revealed no significant difference in survival curves (P = .82). CONCLUSION To our knowledge, this is the longest follow-up study analyzing clinical endpoints stratified by BMI for aTSA. We saw that patients with a higher BMI required shoulder replacement at a significantly younger age. However, we also report that regardless of BMI, all patients saw significant improvements in patient-reported outcomes and range of motion scores postoperatively.

Obesity does not associate with 5-year surgical complications following anatomic total shoulder arthroplasty and reverse total shoulder arthroplasty. J Shoulder Elbow Surg 2022; 32:947-957. [PMID: 36375748 DOI: 10.1016/j.jse.2022.10.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 09/29/2022] [Accepted: 10/12/2022] [Indexed: 11/13/2022]
Abstract
BACKGROUND Although obesity has been shown to increase the risk of short-term medical complications following total shoulder arthroplasty (TSA), evidence is lacking on the influence of obesity on longer-term surgical complications such as revision. The purpose of this study was to assess the association of increasing obesity with 2- and 5-year all-cause revision, periprosthetic joint infection (PJI), aseptic loosening, and manipulation under anesthesia (MUA) among patients undergoing reverse total shoulder arthroplasty (RTSA) or TSA. METHODS Patients who underwent RTSA or TSA with a minimum 5-year follow-up were identified in a national claims database (PearlDiver Technologies). Patients with obesity (body mass index [BMI] ≥30) were compared to patients who are normal or overweight (18.5 ≤ BMI < 30). Those with obesity were further stratified to those with class I or II obesity (30 ≤ BMI < 40) and those with class III obesity (BMI ≥ 40). Outcomes for comparison included all-cause revision, PJI, aseptic loosening, and MUA within 2 or 5 years. These cohorts were compared using univariate and multivariable analysis. RESULTS Patients with obesity had no significant difference in any surgical complication within 2 or 5 years for both those who underwent TSA or RTSA. After stratifying by class I or II obesity and class III obesity, there was still no significant difference in surgical complications with 2 or 5 years for both TSA patients and RTSA patients. DISCUSSION Obesity, when other major comorbidities are controlled for, was not associated with increased risk of long-term surgical complications after shoulder replacement surgery.

Abstract
INTRODUCTION Studies have shown male sex to be a predisposing factor for peri-prosthetic joint infections (PJIs). Symptomatic benign prostatic hyperplasia (BPH) has been suggested as an additional risk for PJI. This study aimed to assess the impact of BPH on (1) lengths of stay (LOS), (2) complications (medical and implant-related), (3) readmission rates, and (4) healthcare expenditures after reverse shoulder arthroplasty (RSA). METHODS Utilizing a nationwide sample from the 2010-2020 PearlDiver insurance database, an analysis was performed retrospectively for all males who underwent primary RSA. Males with BPH (n = 2,184) represented the study group and were ratio-matched with men without a history of BPH (n = 10,832) in a 1:5 manner by medical comorbidities. T-tests compared LOS and healthcare expenditures. Multivariate logistic regression models were used to determine the effect of BPH on 90-day medical complications, 2-year implant complications, and readmissions. A p value less than 0.001 was statistically significant. RESULTS In-hospital LOS (1.96 days vs. 1.99 days, p = 0.683) did not significantly differ between cohorts. Males with BPH had significantly greater occurrence and odds (34.3% vs. 21.2%, odds ratio (OR):1.84, p < 0.0001) of all 90-day medical complications, including urinary tract infections (9.3% vs. 3.1%, OR:3.23, p < 0.0001), pneumonias (6.0% vs. 3.9%, OR:1.61, p < 0.0001), and acute kidney injuries (7.7% vs. 5.0%, OR:1.60, p < 0.0001). Two-year implant-related complications were comparable between study and control groups (12.2% vs 10.9%, OR:1.14, p = 0.073), including PJIs (2.3% vs. 2.2%, OR:1.02, p = 0.874). Readmission rates (1.88% vs. 2.11%, p = 0.482) and average global 90-day reimbursements ($26,301 vs. $24,399), p = 0.535) were similar between men with and without BPH. DISCUSSION Males with a history of BPH have greater rates of medical complications, including UTIs and acute kidney injuries, within 90 days following RSA. BPH does not appear to be a risk factor for 2-year implant-related complications including PJIs. LEVEL OF EVIDENCE III.

Abstract
There has been increasing interest in the use of stemless humeral implants for total shoulder arthroplasty when compared with both short-stem (SS) and standard-length implants. Although evidence for decreased surgical time and blood loss exists for stemless versus standard-length stems, far less literature exists comparing these clinical parameters for stemless versus SS implants.

Abstract
PURPOSE OF REVIEW Rates of obesity and reverse total shoulder arthroplasty (rTSA) in the USA have both escalated with time. Obese patients experience arthritis at higher rates than normal weight patients; therefore, these numbers go hand in hand. Obesity has been correlated with health comorbidities such as anxiety, cardiovascular disease, diabetes, and metabolic syndrome as well as poorer outcomes and higher complication rates following lower extremity arthroplasty. The current review investigates these comorbidities as they relate to obese patients undergoing rTSA. RECENT FINDINGS Functional outcomes are similar to normal weight counterparts. Although longer operative times and a large soft tissue envelope would intuitively predispose these patients to higher risk for infection or other complications, this has not been reliably demonstrated. Technical considerations and awareness of potential risks in the obese patient demographic may aid the surgeon in preoperative planning and counseling of their patient. Obese patients undergoing rTSA have been shown to have higher risks specifically for infection, revision, and medical complications; however, this has not been consistently demonstrated in the single surgeon series where, more often, no difference in these metrics has been found. Outcomes measures and satisfaction are reliably improved, even when considering superobese patients, and majority of studies find their improvements and absolute values to be in line with their normal weight counterparts. Thus, rTSA does not seem to carry the same level of adverse risk associated with lower joint arthroplasty but potential for higher risk still bears consideration when counseling obese patients. Attention to factors that may negatively affect prosthesis positioning may optimize retention rates and limit early failure.

Investigating a Potential Limit to Access to Care: Preoperative Cutoff Values for Body Mass Index for Shoulder Arthroplasty. J Am Acad Orthop Surg 2022; 30:e67-e73.

Abstract
INTRODUCTION The primary purpose of this study was to determine the number of patients who would be denied a complication-free total shoulder arthroplasty (TSA) based on implementation of body mass index (BMI) eligibility cutoffs. METHODS The National Surgical Quality Improvement Program database was queried to identify all patients who underwent primary TSA. Patient demographics and 30-day postoperative complications were compared according to BMI stratification using the Pearson chi-square test and binary logistic regression analysis adjusted for age and modified Charlson comorbidity index. A BMI eligibility criterion of ≥40 kg/m2 was used to calculate the positive predictive value (PPV) to assess the number of complication-free TSAs that would be denied to avoid a complication in a single patient. RESULTS A total of 23,284 patients who underwent TSA met inclusion criteria. The overall complication rate was 7.2%. Using a BMI cutoff of ≥40 kg/m2 would yield a PPV of 7% for all Major Complications. This means that 14 complication-free procedures would be denied to avoid a Major Complication. In addition, BMI ≥40 kg/m2 served as an independent risk factor for acute renal failure, pulmonary embolism, ventilator use >48 hours, and readmission. The PPV for these clinically significant complications using BMI ≥40 kg/m2 as a cutoff was 4.9%. This translates into 20 patients being denied a complication-free procedure to avoid a single clinically significant medical complication. If this policy was enforced on the 2,426 patients who exceeded BMI ≥40 kg/m2 in this study, nearly 2,307 patients would be denied the potential benefit of surgery to prevent 119 complications. CONCLUSION The use of eligibility criteria for primary TSA or RSA based solely on BMI threshold values presents a potential limitation in access to care to these patients who otherwise would have a complication-free procedure.

Abstract
BACKGROUND Baseline health conditions can negatively impact cost of care and risk of complications after joint replacement, necessitating additional care and incurring higher costs. Bundled payments have been used for hip and knee replacement and the Centers for Medicare & Medicaid Services (CMS) is testing bundled payments for upper extremity arthroplasty. The purpose of this study was to determine the impact of predefined modifiable risk factors (MRFs) on total encounter charges, hospital length of stay (LOS), related emergency department (ED) visits and charges, and related hospital readmissions within 90 days after shoulder arthroplasty. METHODS We queried the electronic medical record (EPIC) for all shoulder arthroplasty cases under DRG 483 within a regional 7-hospital system between October 2015 and December 2019. Data was used to calculate mean LOS, total 90-day charges, related emergency department (ED) visits and charges, and related hospital readmissions after shoulder arthroplasty. Data for patients who had 1 or more MRFs, defined as anemia (hemoglobin < 10 g/dL), malnutrition (albumin < 3.4 g/dL), obesity (BMI > 40), uncontrolled diabetes (random glucose > 180 mg/dL or glycated hemoglobin > 8.0%), tobacco use (International Classification of Diseases, Tenth Revision, code indicating patient is a smoker), and opioid use (opioid prescription within 90 days of surgery), were evaluated as potential covariates to assess the relationship between MRFs and total encounter charges, LOS, ED visits, ED charges, and hospital readmissions. RESULTS A total of 1317 shoulder arthroplasty patients were identified. Multivariable analysis demonstrated that anemia (+$19,847, confidence interval [CI] $15,743, $23,951; P < .001), malnutrition (+$5850, CI $3712, $7988; P < .001), and obesity (+$2762, CI $766, $4758, P = .007) independently contributed to higher charges after shoulder arthroplasty. Mean LOS was higher in patients with anemia (5.0 ± 4.0 days vs. 2.2 ± 1.6 days, P < .001), malnutrition (3.7 ± 2.8 days vs. 2.2 ± 1.5 days, P < .001), and uncontrolled diabetes (2.8 ± 2.8 days vs. 2.3 ± 1.7 days, P = .019). Univariate risk factors associated with a significant increase in total 90-day encounter charges included anemia (+$19,345, n = 37, P < .001), malnutrition (+$6971, n = 116, P < .001), obesity (+$2615, n = 184, P = .011), and uncontrolled diabetes (+$4377, n = 66, P = .011). Univariate risk for readmission within 90 days was higher in patients with malnutrition (odds ratio 3.0, CI 1.8, 4.9; P < .001). CONCLUSION Malnutrition, obesity, and anemia contribute to significantly higher costs after shoulder arthroplasty. Medical strategies to optimize patients before shoulder arthroplasty are warranted to reduce total 90-day encounter charges, length of stay, and risk of readmission within 90 days of surgery. Optimizing patient health before shoulder surgery will positively impact outcomes and cost containment for patients, institutions, and payors after shoulder arthroplasty.

Reid JJ, Kunkle BF, Kothandaraman V, Roche C, Eichinger JK, Friedman RJ. Effects of obesity on clinical and functional outcomes following anatomic and reverse total shoulder arthroplasty. J Shoulder Elbow Surg 2022; 31:17-25. [PMID: 34298146 DOI: 10.1016/j.jse.2021.06.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 06/02/2021] [Accepted: 06/12/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Limited data exist regarding the clinical and functional outcomes following primary total shoulder arthroplasty in obese patients. The purpose of this study is to determine the effects of obesity on the clinical and functional outcomes following primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) in a large patient population with mid-term follow-up. METHODS Patients in a multi-institutional shoulder registry receiving either primary aTSA (n = 1520) or rTSA (n = 2054) from 2004 to 2018 with a minimum follow-up period of 2 years were studied. All patients received the same single-platform shoulder prosthesis. Study groups were assigned based on implant type (anatomic or reverse), and further stratification was based on patient body mass index (BMI), with obese patients having a BMI ≥ 30 and non-obese patients having a BMI < 30. Patients were evaluated and scored preoperatively and at latest follow-up by use of 5 scoring metrics and range of motion (ROM). RESULTS The mean follow-up period was 5 years (range, 2-14 years). Obese patients comprised 41% of the aTSA group and 35% of the rTSA group. Significant postoperative improvements in visual analog scale pain scores, ROM, and all 5 scoring metrics occurred in both obese and non-obese patients (P < .05). Obese patients in both groups reported higher preoperative and postoperative visual analog scale pain scores and less preoperative and postoperative ROM compared with non-obese patients. Compared with non-obese patients, obese patients receiving aTSA reported significantly worse postoperative Simple Shoulder Test, Constant-Murley, American Shoulder and Elbow Surgeons, University of California, Los Angeles, and Shoulder Pain and Disability Index scores compared with non-obese patients, and those receiving rTSA reported significantly worse American Shoulder and Elbow Surgeons and Shoulder Pain and Disability Index scores (all P < .05). However, these differences did not exceed the minimal clinically important difference or substantial clinical benefit criteria. Radiographic analysis showed that in the rTSA group, obese patients had significantly less postoperative scapular notching and a lower scapular notching grade compared with non-obese patients (P < .05). DISCUSSION Both non-obese and obese patients can expect clinically significant improvements in pain, motion, and functional outcome scores following both aTSA and rTSA. Obese patients reported significantly more postoperative pain, lower outcome scores, and less ROM compared with non-obese patients after both aTSA and rTSA at a mean follow-up of 5 years. However, statistically significant differences were not found to be clinically significant with respect to established minimal clinically important difference and substantial clinical benefit criteria. Therefore, obese and non-obese patients experience similar clinical outcomes following total shoulder arthroplasty, regardless of BMI. However, obese patients have more comorbidities, greater intraoperative blood loss, and less scapular notching compared with non-obese patients.

Abstract
PURPOSE OF REVIEW Periprosthetic infection is a relatively rare but potentially devastating complication after shoulder arthroplasty. The purpose of this article is to review the incidence, diagnosis, prevention, and management of periprosthetic infections after reverse shoulder arthroplasty, with a focus on literature published within the last 5 years. RECENT FINDINGS The 2018 International Consensus Meeting on Musculoskeletal Infection provides us with a framework for the diagnosis and management of periprosthetic infections after shoulder arthroplasty. Reverse shoulder arthroplasty has a higher reported rate of infection compared with anatomic total shoulder arthroplasty. Our current diagnostic tests do not appear to be as sensitive when compared with the hip and knee literature. Similar success has been reported with single and two-stage revision protocols, although prospective comparative data are lacking. The significance of unexpected positive cultures during revision arthroplasty remains unclear. We report current diagnostic and therapeutic options for periprosthetic infection after reverse shoulder arthroplasty. Much of the current literature does not distinguish between anatomic and reverse shoulder arthroplasty. Further high-level studies are warranted to refine these definitions and guide management.

Abstract
OBJECTIVE The prevalence of obesity and shoulder arthroplasty have both been increasing in the United States. Although lower extremity arthroplasty literature suggests higher complication rates in these patients, there is a paucity of studies evaluating the outcome of shoulder arthroplasty in obese patients. Our purpose was to perform a meta-analysis to determine clinical outcomes and complications of these patients. METHODS Following the PRISMA guidelines, the MEDLINE (PubMed), Embase, and Ovid libraries were used to perform a comprehensive literature review to compare complications and outcomes following shoulder arthroplasty between obese and non-obese patients. Our initial search returned 143 publications. Our inclusion criteria included full-text reports, minimum follow-up of 1 year, minimum of 10 patients, no cadaveric or biomechanical studies, only studies published in English, studies involving obese patients undergoing either anatomic or reverse shoulder arthroplasty. A total of 13 studies met the inclusion criteria. These studies were then evaluating using a methodological index for non-randomized studies (MINORS) score. Ultimately, 6 studies met our criteria and were included in the final analysis. RESULTS A total of 978 patients were identified from the 6 studies. Patients with a BMI <30 kg/m2 had a complication rate of 9.7% and American Shoulder and Elbow Surgeons score (ASES) increased from 37.4 to 76.7. Patients with a BMI >30 kg/m2 had a complications rate of 6.5% and ASES increased from 34.4 to 76.2. Patients with a BMI >40 kg/m2 ASES increased from 29.5 to 68.6. The postoperative ASES score of 68.6 for patients with a BMI >40 kg/m2 was significantly lower than the ASES score of 76.8 in patients with a BMI <40 kg/m2 (p = 0.007). There were an insufficient number of patients and an insufficient number of complications to perform any meaningful statistical test on complication rates in patients with a BMI >40 kg/m2. CONCLUSION No significant difference was observed in number of complications and follow-up ASES scores following shoulder arthroplasty between obese and non-obese patients. Morbidly obese patients (BMI > 40 kg/m2) have a significantly lower ASES follow-up score than non-morbidly obese patients; however, this difference may not be clinically significant. Future studies are needed to investigate outcomes and complications associated with morbidly obese patients undergoing shoulder arthroplasty.

Abstract
BACKGROUND A systematic review was performed to investigate the impact of obesity on outcomes following total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). METHODS Electronic databases and the grey literature were searched for studies that evaluated the influence of obesity (body mass index ≥ 30 kg/m2) on TSA and RTSA outcomes. A total of 15 studies were identified, with 10 studies reporting on predetermined outcomes considered in the TSA and RTSA population. Unadjusted data were pooled in a statistical meta-analysis where appropriate (Review Manager [RevMan], version 5.3) or summarized in narrative form. Effect sizes were expressed as odds ratios (ORs) for categorical data and weighted mean differences (WMDs) for continuous data. RESULTS The findings suggested that patients who were obese were at increased odds of a dislocation (OR, 2.49; 95% confidence interval [CI], 2.32-2.66), fracture (OR, 1.92; 95% CI, 1.77-2.08), and revision (OR, 1.49; 95% CI, 1.40-1.58) following TSA or RTSA. Conversely, obesity had no influence on the odds of an unscheduled return to the operating theater (OR, 0.83; 95% CI, 0.43-1.61). Postoperative forward flexion in patients who were obese differed from that in patients who were not obese (WMD, -9.8°; 95% CI, -17.53° to -2.07°); however, no differences in other functional measures including abduction (WMD, -0.78; 95% CI, -7.27 to 5.71) and external rotation (WMD, -1.41; 95% CI, -5.11 to 2.29) were found. Although patients who were obese reported significantly higher levels of pain (WMD, 1.13; 95% CI, 0.21 to 2.06), the difference was not clinically relevant. CONCLUSIONS Surgeons should consider advising patients who are obese of the greater risk of dislocation, fracture, and revision when considering elective TSA or RTSA. Findings are limited by confounding variables but further our understanding of additional risks associated with pre-existing obesity, which will promote better-informed decisions prior to proceeding with surgery.

Abstract
Background Total shoulder arthroplasty (TSA) has demonstrated good long-term
survivorship but early implant failure can occur. This study identified
factors associated with shoulder arthroplasty revision and constructed a
risk score for revision surgery following shoulder arthroplasty. Methods A validated algorithm was used to identify all patients who underwent
anatomic TSA between 2002 and 2012 using population-based data. Demographic
variables included shoulder implant type, age and sex, Charlson comorbidity
score, income quintile, diagnosis, and surgeon arthroplasty volume. The
associations of covariates with time to revision were measured while
treating death as a competing risk and were expressed in the Shoulder
Arthroplasty Revision Risk Score (SARRS). Results During the study period, 4079 patients underwent TSA. Revision risk decreased
in a nonlinear fashion as patients aged and in the absence of osteoarthritis
with no influence from surgery type or other covariables. The SARRS ranged
from −21 points (5-year revision risk 0.75%) to 30 points (risk 11.4%).
Score discrimination was relatively weak 0.55 (95% confidence interval:
0.530.61) but calibration was very good with a test statistic of 5.77
(df = 8, P = .762). Discussion The SARRS model accurately predicted the 5-year revision risk in patients
undergoing TSA. Validation studies are required before this score can be
used clinically to predict revision risk. Further study is needed to
determine if the addition of detailed clinical data including functional
outcome measures and the severity of glenohumeral arthrosis increases the
model’s discrimination.

Abstract
Background Dislocation of total shoulder arthroplasty has an incidence as high as 31%. Obesity is one of many proposed risk factors, but no consensus exists on this relationship. The purpose of this study was to determine whether there is a relationship between body mass index (BMI) and dislocation of total shoulder arthroplasty. Methods The National Surgical Quality Improvement Program database was used to identify patients older than 50 years who underwent anatomic or reverse total shoulder arthroplasty between the years 2012 and 2016 for primary or secondary osteoarthritis, post-traumatic arthritis, or cuff tear arthropathy. Patients requiring reoperation or readmission for dislocation were identified by Current Procedural Terminology code. The relationship between World Health Organization BMI classification and dislocation was assessed. Results A total of 9382 patients were identified; 46% were male and 54% female, with an average age of 68.7 years (range 50-90) and average BMI of 31.2 (range 15.1-79.3). There were only 24 dislocation events within the first 30 days after the procedure (0.26%). Ten of 24 (42%) occurred after discharge. Seventy percent of cases (17 of 24) required an open procedure. Underweight patients (BMI < 18.5) experienced the highest dislocation rate (1/50, 2.00%), whereas overweight patients (BMI 25-29.9) experienced the lowest dislocation rate (3/3069, 0.1%). Conclusion The rate of dislocation of total shoulder arthroplasty in the acute postoperative period differs across categories of BMI. However, there does not appear to be a linear association between BMI and risk of dislocation of total shoulder arthroplasty. Further studies are required to elucidate the risk factors for total shoulder dislocation.

Abstract
INTRODUCTION To report on the effectiveness of a standardized patient positioning and padding protocol in reducing lateral femoral cutaneous nerve (LFCN) palsy in obese patients who have undergone shoulder surgery in the beach chair position. METHODS We retrospectively reviewed the medical records of 400 consecutive patients with a body mass index (BMI) of ≥30 kg/m who underwent either open or arthroscopic shoulder surgery in the beach chair position by a single surgeon. Before June 2013, all patients were placed in standard beach chair positioning with no extra padding. After June 2013, patients had foam padding placed over their thighs underneath a wide safety strap and underneath the abdominal pannus. Flexion at the waist was minimized, and reverse Trendelenburg was used to position the shoulder appropriately. Patient demographic and surgical data, including age, sex, weight, BMI, presence of diabetes, procedure duration, American Society of Anesthesiologists (ASA) grade, and anesthesia type (general, regional, regional/general) were recorded. Symptoms of LFCN palsy were specifically elicited postoperatively in a prospective fashion and identified clinically by focal pain, numbness, and/or tingling over the anterolateral thigh. RESULTS The median age was 58.0 years, and the study consisted of 142 male (36%) and 258 female (64%) subjects. Five cases (3.6%) of LFCN palsy occurred with conventional beach chair positioning, and a single case (0.4%) occurred with the standardized positioning and padding technique (P = 0.02). Median age, sex, presence of diabetes, median BMI, surgery type, and surgical time were not significantly different between the patients who did and did not develop LFCN palsy. All cases resolved completely within 6 months. DISCUSSION The occurrence of LFCN palsy following shoulder surgery in the beach chair position remains uncommon, even among obese patients. Use of a standardized positioning and padding protocol for obese patients in the beach chair position reduced the prevalence of LFCN palsy. LEVEL OF EVIDENCE Level III (prognostic).

Abstract
BACKGROUND Obesity is a known risk factor for wound complications; however, unlike elective upper extremity procedures, where obesity can be modified preoperatively, excision of soft tissue sarcomas (STSs) is not elective, and as such, obesity cannot be modified. There is a paucity of data concerning the impact of obesity on wound healing in upper extremity sarcoma surgery. METHODS A total of 261 (159 males and 102 females) patients with a STS of the upper extremity from 2006-2014 were reviewed. The mean age and body mass index (BMI) were 56 (18-97) years and 26.6 (15.4-40.8) kg/m2, respectively. Sixty-nine patients (26%) were classified as obese (BMI ⩾30 kg/m2): class I (obese, BMI = 30-34.9 kg/m2; n = 48, 18%), class II (severely obese, BMI = 35.0-39.9 kg/m2; n = 16, 6%), and class III (morbidly obese, BMI ≥ 40 kg/m2; n = 5, 2%). Functional outcomes were also compared between obese and nonobese patients using the Musculoskeletal Tumor Society (MSTS) 1993 rating system and Toronto Extremity Salvage Scores (TESS). RESULTS Forty-nine patients (19%) sustained a wound dehiscence, delayed healing, or infection. Class III obesity increased the risk of wound complications (hazard ratio [HR] = 8.19, 95% confidence interval [CI] = 1.96-22.96, P < .001) and infection (HR = 10.09, 95% CI = 1.60-34.83, P = .01). There was no difference in the mean TESS (93 vs 90, P = .13) or MSTS93 (95 vs 93, P = .39) between obese and nonobese patients. CONCLUSIONS The results of this study indicate morbid obesity significantly increased the risk of a postoperative wound complication and infection. However, following upper extremity limb salvage surgery, obese patients should expect to have excellent functional outcome.

Abstract
PURPOSE Infection is a concern after all orthopedic procedures, including shoulder surgery. This systematic review of literature aimed to determine risk factors for infection as well as the availability and effectiveness of measures utilized to prevent infection after elective shoulder surgery. METHODS An electronic database search was performed using MEDLINE (1950-October 2017), EMBASE (1980-October 2017), CINAHL (1982-October 2017), and the Cochrane database to identify studies reporting a risk factor or preventive measure for infection after shoulder surgery. RESULTS Fifty-one studies were eligible for inclusion. Risk factors identified for infection were male sex, the presence of hair, receiving an intra-articular cortisone injection within the 3 months prior to surgery, smoking, obesity, and several comorbidities. The only preventive measure with level I evidence was for the use of chlorhexidine wipes for cleansing the skin in the days prior to surgery and for the use of ChloraPrep or DuraPrep over povodine and iodine to prep the skin at the time of surgery. Level II-IV evidence was found for other infection prevention methods such as intravenous antibiotic prophylaxis. CONCLUSION There are many risk factors associated with developing an infection after elective shoulder surgery. Many preventive measures have been described which may decrease the risk of infection; however, most lack a high level evidence to support them. The findings of this systematic review are clinically relevant as it has been shown that infection after shoulder surgery results in poor patient-reported outcomes and pose a significant financial burden. As surgeons the goal should be to prevent infections to avoid the morbidity for patients and the increased cost for society. LEVEL OF EVIDENCE IV systematic review of literature.

Abstract
The effect of obesity in shoulder arthroplasty has been recently reported in the literature with different and conflicting results. This review analyzes the role of obesity on outcomes and complications in shoulder arthroplasty. Morbid obesity (body mass index >40 kg/m2), more than standard obesity, is associated with a longer operative time, higher complication rate, reoperation rate and superficial infection. Obesity does not have a detrimental effect on functional outcomes. The magnitude of functional improvement in obese patients, however, can be inferior to that in nonobese patients. Obesity and morbid obesity do not increase hospital charges.

Abstract
Total elbow arthroplasty (TEA) has undergone a significant evolution in indications and outcomes in the past decade. Although rheumatoid patients once had the overwhelming number of TEAs, now TEAs for the sequelae of trauma predominate. Furthermore, as obesity has mirrored the increase in the posttraumatic population, TEA complications have increased whereas the durability of implants under these loads has decreased. Solutions are urgently needed to address the complications and revision burden related to posttraumatic deformity and obesity.

Bariatric Surgery Following Total Shoulder Arthroplasty Increases the Risk for Mechanical Complications Including Instability and Prosthetic Loosening. HSS J 2018; 14:108-113. [PMID: 29983650 PMCID: PMC6031543 DOI: 10.1007/s11420-017-9589-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 10/16/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND While extensive literature has been published on the risks and benefits of bariatric surgery (BS) prior to and following lower-extremity arthroplasty, no similar investigations have been performed on the impact of BS prior to total shoulder arthroplasty (TSA). PURPOSE The objective of the present study was to compare the incidence of mechanical complications in morbidly obese patients who undergo TSA: those who undergo BS following TSA compared with those who do not undergo BS, and those who undergo BS after TSA compared with those who undergo BS prior to TSA. METHODS A Medicare database was queried for morbidly obese patients who underwent BS either before or after TSA, as well as those who underwent TSA but no BS. Of 12,277 morbidly obese patients who underwent TSA between 2005 and 2014, 304 underwent BS (165 of them prior to TSA and 139 following TSA) and 11,923 did not undergo BS. Rates of mechanical complications were then compared between groups using a logistic regression analysis. RESULTS Patients who underwent BS after TSA had significantly higher rates of mechanical complications (12.9%) compared to controls (8.8%) or patients who underwent prior BS (7.9%). Patients who underwent BS after TSA had higher rates of both instability (7.9%) and loosening (8.6%) than did controls (5.1 and 4.9%, respectively) or patients who underwent BS before TSA (4.8 and 4.2%, respectively). CONCLUSIONS BS following TSA is associated with increased rates of mechanical complications, including instability and loosening, compared to BS prior to TSA. These findings suggest that it may be prudent to consider performing BS prior to TSA in morbidly obese patients, rather than waiting until after TSA is performed.

Good functional outcomes expected after shoulder arthroplasty irrespective of body mass index. J Shoulder Elbow Surg 2018; 27:S43-S49. [PMID: 29776471 DOI: 10.1016/j.jse.2018.03.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Revised: 03/26/2018] [Accepted: 03/26/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND This study evaluated how body mass index (BMI) factors into functional outcomes and complications after shoulder arthroplasty. METHODS A retrospective analysis was performed of age-matched patients with a minimum 2-year follow-up after total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), or hemiarthroplasty (HA). Patient-reported outcome (PRO) scores, range of motion (ROM), and complications were assessed. Forty-nine patients were classified into the following groups: normal (BMI <24.9 kg/m2), overweight (BMI 25-29.9 kg/m2), class I obese (BMI 30-34.9 kg/m2), class II obese (BMI 35-39.9 kg/m2), and class III morbid obese (BMI ≥40 kg/m2). RESULTS A total of 245 patients (134 women, 111 men; average age, 64 ± 8 years) were evaluated at an average follow-up of 48 ± 18 months. TSA was performed in 122 patients (50%), RTSA was performed in 103 (42%), and HA was performed in 20 (8%). No significant difference was found among the 5 BMI groups in arthroplasty type (P = .108) or in complications, including reoperations (P = .27). All groups had significant postoperative improvements in PROs and ROM (P < .001 for both). There were no significant differences among the BMI groups in postoperative ROM or PROs. DISCUSSION This study demonstrates that patients undergoing TSA, RTSA, and HA can expect good functional outcomes, with improvements in pain, function and outcome scores, irrespective of BMI.

Abstract
BACKGROUND Although diabetes mellitus (DM) has been established as a risk factor for infection after lower extremity arthroplasty, no association has been reported with shoulder arthroplasty. METHODS We queried a national database for patients with DM who underwent primary shoulder arthroplasty. We identified perioperative hemoglobin A1c (HbA1c) levels and assessed the incidence of wound complications within 6 months and deep infection that required surgical intervention within 1 year for each HbA1c level. We performed a receiver operating characteristic analysis to determine a threshold value of HbA1c. RESULTS Patients with DM had markedly higher rates of wound complications (1.4% versus 0.9%; odds ratio, 1.22; P = 0.028) and deep infection (0.7% versus 0.4%; odds ratio, 1.47; P = 0.001). The rates of wound complications (P = 0.0008) and deep postoperative infection (P = 0.002) increased markedly as the perioperative HbA1c level increased. Receiver operating characteristic analysis demonstrated an inflection point at an HbA1c level of 8.0 mg/dL (P = 0.017; sensitivity, 50%; specificity, 75%). CONCLUSIONS The risk of wound complications and deep postoperative infection in patients with DM increases as the perioperative HbA1c level increases. An HbA1c level >8.0 mg/dL could serve as a threshold for a markedly increased risk of infection. LEVEL OF EVIDENCE Therapeutic level III, case-control study, treatment study.

Abstract
INTRODUCTION Obesity is an epidemic nowadays and this fact conditions results in orthopaedic surgery. Very few studies evaluates if obesity is a risk factor for reverse shoulder arthroplasty. The aim of this study is to confirm if there are differences with regard to the outcomes in patients undergoing reverse shoulder arthroplasty according to their body mass index (BMI). MATERIALS AND METHODS A total of 35 patients were enrolled in the study. Then divided into subpopulations according to their BMI and analyzed twice. First analysis set a division 30 of BMI and second set it in 35. ASES score, major complications, length of the hospital stay, radiolucent lines in components as well as scapular notching were assessed. RESULTS No major complications were described in our patients. No differences were found related to hospital stay, radiolucent lines or scapular notching. However, in the second analysis (BMI < 35 and ≥ 35) statistical differences were found regarding ASES score. Poorer functional outcomes were described in the type-II obese and morbidly obese population. CONCLUSION Functional outcomes of reverse shoulder arthroplasty are worse in patients with a BMI over 35.

Abstract
INTRODUCTION The escalation in the prevalence of obesity throughout the world has led to an upsurge in the number of obese surgical patients to whom perioperative care needs to be delivered. SOURCES OF DATA After determining the scope of the review, the authors used PubMed with select phrases encompassing the words in the scope. Both preclinical and clinical reports were considered. AREAS OF AGREEMENT There were no controversies regarding preoperative management and the intraoperative care of the obese surgical patient. AREAS OF CONTROVERSY Is there a healthy obese state that gives rise to the obesity paradox regarding postoperative complications? GROWING POINTS This review considers how to prepare for and manage the obese surgical patient through the entire spectrum, from preoperative assessment to possible postoperative intensive care. AREAS TIMELY FOR DEVELOPING RESEARCH What results in an obese patient developing 'unhealthy' obesity?

Abstract
BACKGROUND Instability after shoulder arthroplasty remains a complication with limited salvage options. Reoperation for instability with anatomic designs has led to high rates of persistent instability, therefore we aimed to evaluate the use of RSA for treatment of prosthetic instability. QUESTIONS/PURPOSES (1) After revision shoulder arthroplasty to a reverse prosthesis (RSA), what is the survivorship free from dislocations at 2 and 5 years? (2) What factors are associated with dislocations? (3) What is the survivorship free from revision after revision to RSA? (4) From preoperation to postrevision to RSA, what are the clinical outcomes-the proportion of patients with moderate to severe pain, shoulder elevation and external rotation ROM, American Shoulder and Elbow Surgeons scores, and Simple Shoulder Test scores? METHODS All shoulder arthroplasties revised for prosthetic instability using RSA components between January 2004 and July 2014 were retrospectively studied. During the period in question, we performed 82 revisions for instability of an anatomic total shoulder arthroplasty (TSA) (n = 62), hemiarthroplasty (n = 13), or reverse TSA (n = 7). We typically used a reverse TSA to treat this problem, but we identified 12 treated in other ways, including revision of a TSA to hemiarthroplasty (n = 3), revision of a reverse TSA to hemiarthroplasty (n = 2), revision of hemiarthroplasty to a hemiarthroplasty (n = 1), and revision of an anatomic TSA to another anatomic TSA (n = 6). This left 70 patients for evaluation; of those, 65 (93%) were available for analysis at a mean of 3 years (range, 2-10 years). A total of seven patients died. Eight of the 65 shoulders were not evaluated during the last 5 years, including three in patients who died earlier. The mean age of the patients at the time of revision RSA was 65 years (range, 40-89 years). Data were obtained from a longitudinally maintained institutional joint registry. Instability was defined as severe subluxation confirmed on clinical and radiographic examinations. We evaluated pain and ROM, and Kaplan-Meier curves were used to estimate survivorship. RESULTS The survivorship free from dislocation at 2 and 5 years was 87% (95% CI, 80%-94%) and 79% (95% CI, 67%-91%) respectively, with 10 of 65 (15%) patients having an episode of dislocation after revision surgery. Persistent instability was more common in those with a BMI greater than 35 kg/m2 (hazard ratio [HR], 5; 95% CI, 2-16; p = 0.008) and prior hemiarthroplasty (HR, 5; 95% CI, 2-16; p = 0.005), whereas patients who had undergone a previous TSA were less likely to have persistent instability (HR, 0.08; 95% CI, 0.0-0.30; p < 0.001) The survival free from rerevision for any indication at 2 and 5 years was 85% (95% CI, 76%-94%) and 78% (95% CI, 66%-90%) respectively; with the numbers available, we were not able to find associated factors. Fewer patients had moderate or severe pain after revision to RSA (preoperative: 48 of 65 [74%]; postoperative: nine of 65 [14%]; p < 0.001). After surgery, patients showed improvement in shoulder elevation (preoperative: 42° [± 30°], postoperative: 112° [42°]; mean difference, 70° [95% CI, - 83o to 57°]; p < 0.001) and external rotation (preoperative: 20° [± 22°], postoperative: 42° [± 23°]; mean difference, 22° [95% CI, - 30° to - 14°]; p < 0.001). American Shoulder and Elbow Surgeons scores improved (preoperative: 21 [± 10], postoperative: 68 [± 14], mean difference, 46 [95% CI, - 58 to - 35]; p < 0.001); where a higher score is better. Simple Shoulder Test scores also improved (preoperative: 2/12 [± 2], postoperative: 7/12 [± 3]; mean difference, 5 [95% CI, - 7 to - 2.17]; p < 0.001); where a higher score is better. CONCLUSIONS Revision RSA for prosthetic instability after shoulder arthroplasty is associated with reasonable implant survival and few complications. Approximately one in seven patients will have a recurrent dislocation. In patients with persistent instability or with risk factors for instability, consideration should be given for use of larger glenospheres and increasing the lateral offset at the time of RSA.

Abstract
INTRODUCTION Previous reports have shown an increased risk of complications after arthroplasty in the obese population. It remains unclear if gastric bypass surgery prior to shoulder arthroplasty modifies the complication and failure rate. The purpose of this study is to assess the complication and re-operation rates following shoulder arthroplasty in this population. METHODS Between 2002 and 2012, 39 shoulders with prior gastric bypass underwent shoulder arthroplasty (3 HA, 16 TSA, 20 RSA). The mean time from the gastric bypass to arthroplasty was 13 years (range, 0.7-32). Shoulders were followed for a minimum of two years (mean, 3.8 years) or until re-operation. Outcome measures included pain, range of motion, satisfaction, modified Neer ratings, and ASES scores. RESULTS Complications occurred in seven shoulders (18%), with five requiring re-operation. There was no common failure mechanism. Re-operations occurred for aseptic glenoid loosening, periprosthetic fracture, and unexplained pain. Those shoulders with complications were similar to those without in regard to age, sex, and BMI. Complications were more common following anatomic arthroplasty compared to reverse arthroplasty (5 vs 1, p = 0.06); however, complications were not improved compared to historical controls with morbid obesity. Overall, pain improved significantly from 4.8 pre-operatively to 2.3 postoperatively (p < 0.001). All groups, regardless of arthroplasty type, demonstrated significant improvements in forward elevation and external rotation. CONCLUSION Gastric bypass surgery prior to shoulder arthroplasty leads to clinical improvement in both pain and range of motion. Prior gastric bypass surgery does not result in a lower surgical complication rate compared to previously published reports in the morbidly obese population. LEVEL OF EVIDENCE Level 4, case series.

Abstract
INTRODUCTION The purpose of this study was to identify the effects of body mass index (BMI) on long-term outcomes (revision rate, 1-year mortality rate, 3-year surgical site infection rate, and 90-day inpatient all-cause readmission rate) after total shoulder arthroplasty (TSA) and reverse TSA (RTSA). METHODS A large shoulder arthroplasty registry was used to review outcomes after TSA and RTSA. The registry monitors patient's revision, mortality, infection, and readmission rates. The exposure of interest was the patient's BMI at the time of the surgery, which was stratified by 5 kg/m2 increments. RESULTS Selected for this study were 4630 patients who underwent TSA and RTSA between 2007 and 2013, of which 3483 (75.2%) were TSA and 1147 (24.8%) were RTSA. The overall combined (TSA and RTSA) revision rate was 1.7%. After adjusting for confounders in the overall models (TSA and RTSA combined), higher BMI was not associated with higher risk of aseptic revision, 1-year mortality, or 3-year deep infection. In TSA-specific models, every 5 kg/m2 increase in BMI was marginally associated with a 16% increase in the likelihood of 90-day readmission. This association was not observed in the RTSA model. In RTSA-specific models, every 5 kg/m2 increase in BMI was marginally associated with higher risk of 3-year deep infection. This association was not observed in the TSA model. CONCLUSION Shoulder arthroplasty in obese patients is not associated with higher risk of aseptic revision. The BMI has different effects on TSA and RSA. The surgeon should anticipate increased risk of readmission after TSA and infection after RSA.

Abstract
BACKGROUND This study evaluated and identified risk factors for the development of intraoperative and postoperative surgical complications in total shoulder arthroplasty in patients with primary osteoarthritis. METHODS We evaluated patient-specific factors, including age, sex, body mass index, prior nonarthroplasty surgery, smoking, alcohol consumption, and the American Society of Anesthesiologists (ASA) Physical Status Classification System in 275 patients (76 men, 199 women) with an average age of 68 years (range, 51-85 years). We categorized the number and severity of all complications and correlated these results with the patient-specific factors RESULTS: Twenty-seven complications (9.8%) in 275 shoulder arthroplasties were recorded. We identified 22 patients (8%) with category I complications and 5 (2.8%) with category II complications. Patients with an ASA score of 3 showed an increased likelihood of having a surgical complication compared with the control group with ASA scores of 1 and 2 (odds ratio, 4.28; 95% confidence interval, 1.79-10.20; P < .01). Smokers were more prone to surgical complications than nonsmokers (odds ratio, 5.08; 95% confidence interval, 1.96-13.11; P = .02). CONCLUSION Surgical complication rates after anatomic total shoulder arthroplasty in patients with primary osteoarthritis correlate with the patient's overall health status and nicotine consumption. This may be useful for predicting the likelihood of surgical complications and may thus prove important for clinicians to better assess and explain possible risks before surgery.

Abstract
Background Shoulder pain and loss of function are directly associated with obesity. Questions/purposes We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA. Prospectively collected data of patients with a TSA or RSA were reviewed (N = 310). Preoperative, 2-year, and final follow-up visits were included (range 3–17 years; mean 5.0 ± 2.5 years). Patient data were stratified for analysis using BMI. Results Morbidly obese patients had worse preoperative functional scores and QOL compared to the other groups. There were no significant interactions of BMI group by surgery type for any of the outcome variables except for active external rotation ROM. Morbidly obese patients attained lower SF-12 scores compared to the remaining groups at each time point. Conclusions Both TSA and RSA can be expected to impart positive functional outcomes in patients irrespective of BMI. Morbidly obese patients do not attain the same gains in Medical Outcomes SF-12 scores as the non-morbidly obese patients. The lower improvements in active external ROM may be due to morphological limitations of excessive adiposity. Level of evidence This is a level II study.

[PMID: 27209623 DOI: 10.1016/j.arthro.2016.03.022] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2015] [Revised: 03/02/2016] [Accepted: 03/15/2016] [Indexed: 02/08/2023]
Abstract
PURPOSE To report the prevalence of obesity in shoulder arthroscopy, determine a body mass index (BMI) threshold most predictive of complication within 30 days, and evaluate obesity as an independent risk factor for medical and surgical complications. METHODS Using the National Surgical Quality Improvement Program database, we reviewed all patients who underwent shoulder arthroscopy during 2011 to 2013. Receiver operating characteristic and Youden coefficient were calculated to find an optimal BMI cutoff to predict complications within 30 days of surgery. A case-control matched analysis was then performed by stratifying patient BMI by this cutoff and matching patients one to one according to age, sex, type of shoulder arthroscopy, American Society of Anesthesiology rating, surgical setting, and 8 comorbidities. Operating time, complications, and readmissions were also compared. RESULTS Of the 15,589 patients who underwent shoulder arthroscopy, 6,684 (43%) were classified as obese when using the optimal cutoff point of BMI = 30 according to the Youden coefficient. Obese patients had a higher risk of superficial site infection than nonobese patients (0.3% vs 0.0%; odds ratio [OR]: 6.00; 95% confidence interval [CI], 1.3 to 26.8; P = .015). Obese patients did not have significantly increased risk for overall early postoperative complication (1.2% compared with nonobese 0.8%; OR: 1.54; 95% CI, 1.0 to 2.4), readmissions (OR: 0.85; 95% CI, 0.5 to 1.5), or increased operating time (P = .068). CONCLUSIONS Up to 43% of patients undergoing shoulder arthroscopy can be classified as obese, but early perioperative complications are uncommon. Higher patient BMI is associated with increased risk of superficial site infection but not an overall risk for complication, readmission, or increased operating time. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Prosthetic shoulder infection can cause significant morbidity secondary to pain and stiffness. Symptoms may be present for years before diagnosis because clinical signs are often absent and inflammatory markers may be normal. An emerging common culprit, Propionibacterium acnes, is hard to culture and so prolonged incubation is necessary. A negative culture result does not always exclude infection and new synovial fluid biochemical markers such as α defensin are less sensitive than for lower limb arthroplasty. A structured approach is necessary when assessing patients for prosthetic shoulder joint infection. This includes history, examination, serum inflammatory markers, plain radiology and aspiration and/or biopsy. A classification for the likelihood of prosthetic shoulder infection has been described based on culture, pre-operative and intra-operative findings. Treatment options include antibiotic suppression, debridement with component retention, one-stage revision, two-stage revision and excision arthroplasty. Revision arthroplasty is associated with the best outcomes.
