The use of reverse shoulder arthroplasty (RSA) continues to grow with expanding indications and increased surgeon awareness. Previous data for other lower extremity joint replacements indicate that high-volume centers have better outcomes, with lower complication rates, decreased length of stay, and complications for both hemiarthroplasty and total shoulder arthroplasty. The purpose of this study is to evaluate the effects of hospital size and setting on adverse events for RSA. The National Inpatient Sample database was queried for RSA performed using ICD-9 codes. Primary outcomes included length of stay (LOS), total hospital charges, discharge disposition, and postoperative complications. Odds ratios were used to assess the risk of inpatient postoperative complications. A weighted national estimate of 24,056 discharges for patients undergoing RSA was included in the study. Patients at larger hospitals experienced higher total charges, increased average LOS, and slightly higher complication rates compared to those of small and medium hospitals. Patients in larger hospitals had significantly increased rates of genitourinary and central nervous system complications, while patients in small/medium hospitals experienced higher rates of hematoma/seroma. Results from this study indicate that large and non-teaching hospitals overall tend to burden the patients with higher hospital charges, longer hospital stay, and more frequent non-routine discharges. Also, larger hospitals are associated with higher risk of genitourinary and central nervous system complications rates, whereas non-teaching hospitals are associated with lower risk of infection and higher risk of anemia after RSA. With the growth in RSA in the USA, continued attention needs to be placed on improving outcomes and resource utilization for RSA patients even in larger hospitals.

Background Preoperative opioid use has been correlated to suboptimal outcomes in orthopedic surgery. This study evaluated the effect of preoperative opioid use on outcomes after arthroscopic rotator cuff repair (RCR). Methods A retrospective review was performed of 79 patients who underwent arthroscopic RCR; of these, 31 with a history of preoperative opioid use were compared with a control group of 48 patients without a history of preoperative opioid use. Preoperative and postoperative patient-reported outcomes and functional scores were compared. Results Both cohorts significantly improved on all patient-reported shoulder scores; however, the nonopioid group demonstrated significantly better postoperative patient-reported outcome scores (P = .015) and external rotation measurement (P = .008). Functional outcomes also significantly improved from preoperatively to postoperatively for forward flexion, but no differences were seen between groups. Conclusions Patients with a history of preoperative opioid use can still achieve significant improvements in outcomes after arthroscopic RCR, although not to the same extent as opioid-naive patients. Therefore, orthopedic surgeons must consider a patient's preoperative opioid use and temper expectations with regard to outcomes so that they are able to set realistic postoperative goals for patients undergoing RCR.

The influence of socioeconomic status and insurance type has not been studied extensively for RCR, particularly not in the high risk massive RCT population. The purpose of this study is to identify relationships between Medicaid payer status and patient outcomes following massive RCR. A retrospective review of shoulder surgery database identified 29 patients undergoing massive rotator cuff repair. Patients were stratified based on insurance type into two cohorts, Medicaid (14 patients) and non-Medicaid (15 patients). Missed routine follow-up appointments and comorbidities were recorded and compared between groups. Group comparisons were made for pre- and postoperative patient-reported and functional outcomes. Outcome scores included American Shoulder and Elbow Shoulder Score (ASES), the Penn Shoulder Score, and the Subjective Shoulder Value (SSV). A p value of

Fatty atrophy is a diagnosis characterized by the combination of fatty infiltration and muscle atrophy of the rotator cuff. Studies have shown a strong positive correlation between the level of fatty infiltration and the risk of experiencing a chronic rotator cuff tear. Therefore, the purpose of the present study was to review the current literature on radiographic imaging of fatty infiltration and fatty atrophy to better aid surgeons in predicting functional outcome and to help guide patient decisions.We conducted a literature search in PubMed. The exact search queries included "rotator cuff" in the MeSH Terms field; "fatty atrophy," fatty infiltration," and "fatty muscle degeneration" in the Title/Abstract field; and various combinations of these searches. We initially found 184 articles using these keywords, including both human and animal studies. The 25 animal studies were excluded, leaving 159 articles. The abstracts of all remaining articles were reviewed and selected on the basis of our inclusion criteria of focusing on patients with rotator cuff tears (preoperatively and postoperatively), fatty infiltration, fatty atrophy, and imaging modalities. We excluded an additional 127 articles, leaving 32 articles that were selected for the final review and inclusion in this study.Among 45 shoulder specialists across different studies, interrater agreement for Goutallier staging with use of magnetic resonance imaging (MRI) ranged from 0.24 to 0.82 and intrarater agreement for supraspinatus fatty changes ranged from 0.34 to 0.89. Our review also showed strong positive correlations when assessing the severity of fatty atrophy of the rotator cuff between MRI and ultrasound or ultrasound modalities such as sonoelastography.Increasing fatty infiltration of the rotator cuff is associated with greater repair failure rates and hence poorer overall clinical outcomes. MRI remains the gold standard for the imaging of rotator cuff tears and postoperative healing. Ultrasound can decrease health-care expenditures associated with the assessment of repair integrity postoperatively, although ultrasound is not as precise and has some limitations compared with MRI.

Orthopaedic surgery maintains a large portion of the total health-care spending in the United States. In the near future, a greater importance will be placed on efforts to curtail health-care spending and on providing cost-effective care.The literature has established that there are substantial trea

Background Shoulder arthroplasty is the fastest growing joint replacement surgery in the United States, and optimal postoperative pain management is critical to optimize outcomes for these surgeries. Liposomal bupivacaine (LB) has gained popularity for its potential to provide extended postoperative pain relief with possibly fewer side effects. The goal of this study was to assess the impact of LB compared with continuous interscalene nerve block (CISB) in terms of postoperative pain control, outpatient pain scores, and patient-reported and functional outcomes after shoulder arthroplasty surgery. Methods A prospective randomized controlled clinical trial compared consecutive patients undergoing shoulder arthroplasty treated with CISB vs. LB with a single bolus interscalene block. The primary outcome measures included pain assessment up to 24 hours after surgery; in addition, all doses and times of narcotics administered during the inpatient stay were recorded. Patient-reported outcome measures for pain, satisfaction, and functional outcomes were recorded postoperatively. Results A total of 70 of 74 consecutive patients who underwent shoulder arthroplasty were included in the study. The LB group had equivalent narcotic use, pain scores, and time to first narcotic rescue compared with the CISB group within the first 24 hours (P > .05). The LB group had higher American Shoulder and Elbow Surgeons score and Penn Shoulder Score at final follow-up. There was an increased number of complications and cost for the CISB group. Conclusion This prospective randomized controlled trial demonstrated that LB provides excellent postoperative pain relief for shoulder arthroplasty patients. In addition, LB had fewer complications and lower cost, making it a promising addition to a multimodal pain regimen for shoulder arthroplasty.

Background: The published return-to-play (RTP) rates for Major League Baseball (MLB) pitchers who have undergone surgical repair of superior labrum anterior-posterior (SLAP) tears vary widely and are generally accepted to be lower in the subset of competitive throwers. The efficacy of surgical treatment for MLB players is largely unknown. Purpose: To examine the RTP rate and performance of MLB pitchers who have undergone SLAP tear repair between 2003 and 2010. Study Design: Descriptive epidemiological study. Methods: A retrospective review of MLB pitchers undergoing SLAP repair was performed using the MLB disabled list. Data collected included the following player statistics: earned run average (ERA), walks plus hits per inning pitched (WHIP), and innings pitched (IP). The mean values for performance variables both before and after surgery were compared. A definition of return to prior performance (RTPP) was established as an ERA within 2.00 and WHIP within 0.500 of preoperative values. Results: Twenty-four MLB players met inclusion criteria, of which 62.5% were able to RTP at the MLB level after SLAP repair surgery. Of those able to RTP, 86.7% were able to RTPP. However, the overall rate of RTPP, including those unable to RTP, was 54.2%. Mean performance analysis of the RTP group revealed a statistically significant decrease in IP for MLB pitchers throwing a mean 101.8 innings before injury and 65.53 innings after injury ( P = .004). Conclusion: Of those pitchers able to RTP, chances of a full recovery were good (86.7%). Our results indicate the need for future research aimed at proper surgical selection of who will return to play, as they will likely achieve full recovery. We believe this information can help surgeons advise high-level overhead-throwing athletes about expected outcomes for surgical treatment of SLAP tears.

The treatment of proximal humerus fractures (PHF) is largely surgeon dependent with no clear guidelines for selecting the optimal method of treatment. The aim of this study was to evaluate trends and variations in treatment methods of PHF in the United States from 2004 to 2012 and to determine the regional differences in treatment. The National Inpatient Sample was used to identify all patient discharges with diagnosis codes for PHF and the data were classified based on ICD-9 procedure codes. Patient and hospital demographics were also analyzed. Simple linear regression analyses were performed for each treatment modality to evaluate current treatment trends and to extrapolate the future trends of PHF treatment over the next 20 years. A national estimate of 550,116 PHF discharges was identified over the time period. Significant correlations between change over time and treatment modality were found for reverse shoulder arthroplasty (RSA) (r = 0.903, p

Low socioeconomic status and Medicaid insurance as a primary payer have been associated with major disparities in resource utilization and risk-adjusted outcomes for patients undergoing total joint arthroplasty. With the expansion of Medicaid through the Affordable Care Act in 2014, examination of these disparities has become increasingly relevant for the treatment of proximal humerus fracture (PHF).The Healthcare Cost and Utilization Project Nationwide Inpatient Sample database was used to identify patients who were treated for PHF from 2002 to 2012. Primary outcomes included treatment type, surgical fixation method, in-hospital complications, mean length of stay, and mean total charges for Medicaid patients vs. a matched privately insured cohort. In an effort to minimize confounding variables, each Medicaid patient was matched to a privately insured patient on the basis of gender, race, year of procedure, and age.Of the 678,831 patients treated with PHF, 4.9% (33,263) had Medicaid as the primary payer during the 10-year period. Medicaid patients were found to have a significantly higher risk (P .05) of postoperative in-hospital complications, including postoperative infection (odds ratio [OR], 2.00 [1.37-2.93]), wound complications (OR, 1.69 [1.04-2.75]), and acute respiratory distress syndrome (OR, 1.34 [1.15-1.59]).Medicaid patients have a significantly higher risk for certain postoperative hospital complications and consume more resources after treatment for PHFs. Additional work is needed to understand the optimal treatment type for Medicaid patients and to understand the complex interplay between socioeconomic status and outcomes to ensure appropriate resource allocation and risk stratification.
