Compared with TSA, reverse TSA was associated with less suitability for discharge (P=.01). On querying the ACS-NSQIP database, 15,254 patients were identified. Female sex, BMI less than 35 kg/m2, American Society of Anesthesiologists class III/IV, preoperative anemia, functional dependence, low preoperative albumin, and hemiarthroplasty were associated with unsuitability for discharge. Males 55 to 59 years old with no comorbidities nor history of narcotic use formed the lowest risk subgroup. Transfusion is the primary driver of AEs. Strategies to avoid this complication should be explored. Risk stratification will improve the ability to identify patients who can safely undergo outpatient shoulder arthroplasty. [Orthopedics. 2021;44(x)xx-xx.].Nonsteroidal anti-inflammatory drugs can delay bone healing. This knowledge is mainly derived from retrospective and animal studies. The authors therefore conducted a human study to investigate whether ibuprofen affects radiological, functional, densitometrical, and biochemical outcomes following a Colles' fracture, as well as the analgesic effect of ibuprofen. This was a single-center, triple-blinded, randomized, placebo-controlled clinical trial with a total of 96 patients. All of the patients received basic treatment with 1000 mg of acetaminophen 4 times daily. The placebo group received a placebo for 7 days. The 3-day ibuprofen group received 600 mg of ibuprofen 3 times daily for the first 3 days and a placebo for the following 4 days. The 7-day ibuprofen group received ibuprofen 3 times daily for 7 days. The primary outcome was the fragment migration for a period of 5 weeks. The secondary outcomes were changes in the wrist's range of motion; Disabilities of the Arm, Shoulder and Hand score; bone mineral density of the injured wrist; changes in serum CrossLaps (Roche Diagnostics) and osteocalcin; and analgesic effects. Analyses were performed according to an intention-to-treat approach. No significant differences in radiological migration or functional, densitometrical, and biochemical effects were established among the treatment groups (.06≤P≤.9). During the first 3 days, the pain score was lower (P=.02) in the ibuprofen groups than in the placebo group. The findings of this study offer an indication for ibuprofen as a bone-safe analgesic treatment after Colles' fracture and may be translated into other fields of cancellous bone fracture treatment. [Orthopedics. 2021;44(x)xx-xx.].Spinal muscular atrophy (SMA) is a neuromuscular disease with manifestations of scoliosis, pulmonary function decline, and, uniquely, collapse of the ribs. Methods to quantify rib deformity and its impact on pulmonary function are sparse. The authors propose new radiographic measurements to quantify the aspect of SMA known as collapsing parasol deformity and correlate these measurements with pulmonary function. Twenty-eight full-spine radiographs of pediatric SMA patients were measured twice by 3 independent investigators, with 2 weeks separating each measurement. Radiographic measurements, demographics, spirometry results, and assisted ventilation rating were obtained. Twenty-one patients with spirometry metrics were assessed to correlate pulmonary function and spinal measurements. The intrarater intraclass correlation coefficient (ICC) for the measurements ranged from 0.706 to 0.99, and the interrater ICC ranged from 0.64 to 0.97. Eighteen of 19 variables had ICC values greater than 0.75 for inter- and intrarater reliability. Twenty-one patients with forced expiratory volume in 1 second and forced vital capacity were assessed in terms of these measurements. Ratio of the concave hemithoracic width at T6/convex hemithoracic width at T6 (P=.004) and ratio of convex vertical rib displacement at the apical rib/concave vertical rib displacement (P=.021) were both significantly correlated with decreased pulmonary function. No significant correlation was found examining the average vertical rib displacement at the apical rib. High inter-and intrarater reliability can be obtained in a variety of spinal measurements of SMA patients. Various measurements are correlated to diminished pulmonary function, specifically variables showing asymmetric changes in the chest cavity. [Orthopedics. 2021;44(x)xx-xx.].Postoperative acute kidney injury occurs in 7% to 11% of orthopedic surgeries. The effect of preoperative angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) on the development of postoperative acute kidney injury remains controversial. Adipose tissue has its own independently regulated angiotensin system. The primary aim of this study was to examine the effects of obesity and preoperative ACEIs and ARBs on postoperative acute kidney injury. Charts were reviewed of adult elective orthopedic surgery patients during a 2-year period when patients were instructed to take their ACEI or ARB on the morning of surgery. The patients were divided into an obese cohort (body mass index [BMI] ≥30 kg/m2) and a nonobese cohort (BMI less then 30 kg/m2). A multivariable model was created for the outcome of acute kidney injury, using obesity as a primary predictor and adjusting for demographics, medications, comorbidities, and intraoperative parameters in a logistic regression analysis. Obesity increased the likelihood of developing acute kidney injury after orthopedic surgery (odds ratio [OR], 1.86; 95% CI, 1.07-3.22; P=.028). For every 5-unit increase in BMI, the odds of acute kidney injury were 1.43 (95% CI, 1.26-1.62; P less then .001). When receiving ACEIs or ARBs, only the nonobese patients had a statistically increased likelihood of postoperative acute kidney injury (OR, 3.30; 95% CI, 1.12-9.70; P=.030). Obesity is an independent risk factor for postoperative acute kidney injury. Obesity appears to influence the effect that preoperative ACEIs and ARBs have on postoperative acute kidney injury. [Orthopedics. 2021;44(x)xx-xx.].On clinical observation, it was found that the bone mineral density (BMD) of the femoral head and proximal femur was not consistent in some patients with femoral neck fracture after surgery. The current study was performed to explore whether this phenomenon was associated with femoral head necrosis after surgery for femoral neck fracture. Bone mineral density inconsistency is when the difference of the sum of pixel values on both sides of the fracture line has exceeded 30%. Statistical analysis was performed on the clinical characteristics of 271 patients who have received the operation for femoral neck fracture. Chi-square test, Spearman rank correlation, independent sample t test, Kaplan-Meier method, and log-rank test, as well as univariate Cox regression and multivariate Cox regression, were used to analyze the potential relationship among related factors. It was revealed that the incidence of inconsistency in BMD between the femoral head and proximal femur was significantly increased in patients with femoral head necrosis after surgery for femoral neck fracture, and that the consistency was considerably high between BMD inconsistency and femoral head necrosis. The inconsistent BMD occurred 11.1 months earlier than the necrosis of the femoral head. Cox multivariate regression analysis indicated that the inconsistency in BMD between the femoral head and proximal femur after surgery for femoral neck fracture was an independent prognostic factor affecting femoral head necrosis. The inconsistent changes in BMD between the femoral head and proximal femur after surgery for femoral neck fracture indicate a great possibility of femoral head necrosis. [Orthopedics. 2021;44(x)xx-xx.].Maryland implemented the all-payer, rater-setting Global Budget Revenue (GBR) payment model in 2014 to reduce cost and improve quality. This study assessed the effect of GBR on total knee arthroplasty (TKA) outcomes by sex. Specifically, the authors assessed (1) demographics and (2) outcomes of males and females undergoing TKA before and after GBR implementation. The Maryland State Inpatient Database was queried from 2011 to 2016. There were 71,066 TKAs (male, n=25,413; female, n=45,634). For continuous and categorical variables, t testing and chi-square analyses were used, respectively. EGFR-IN-7 Difference-in-difference analyses using multiple regression compared changes in sex from the pre-GBR period (2011-2013) with the post-GBR period (2014-2016). The female proportion decreased (-1.9%; P=.040). Proportionally more TKA patients were Hispanic and Asian, from high-income areas, using Medicare and Medicaid, and morbidly obese (all P less then .001). The mean length of stay (LOS), charges, and costs were decreased after GBR implementation (all P less then .001). More patients were discharged routine and had fewer readmissions (both P less then .001). There were fewer complications, including deep venous thromboses/pulmonary emboli, urinary tract infections, and blood transfusions (all P less then .001). The difference-in-difference analyses suggested more females were discharged with home health care and had longer LOS than did males (both P less then .001). The GBR appears to meet its main objective of cost reduction and improvements in quality of care. However, the proportion of females receiving TKA decreased, and their LOS did not improve as much as that of males. As other states consider global budgets, more research is needed to ensure this all-payer, rate-setting, capitated system does not cause decreased access to care. [Orthopedics. 2021;44(x)xx-xx.].Stiffness after total knee arthroplasty (TKA) remains a challenging problem. Angiotensin receptor blockers (ARBs) have been associated with decreased muscle fibrosis. The aim of this study was to evaluate whether perioperative use of ARBs was associated with a reduction in arthrofibrosis and manipulation under anesthesia (MUA) in patients undergoing primary TKA at 90 days and 1 year postoperative. In this retrospective study, the authors used a national database to evaluate patients undergoing TKA for primary osteoarthritis from 2007 to 2017. They evaluated patients with filled prescriptions for ARBs within the study time frame and the specific type of ARB and its association with arthrofibrosis and MUA. After adjusting for age, sex, a comorbidity index, and obesity, any ARB or specific ARBs were not associated with a reduction in the rate of arthrofibrosis or MUA after TKA (P≥.05). Male sex, age 55 years or older, and obesity were associated with a reduction in the rate of arthrofibrosis and MUA after TKA (P≤.05). Studies should be performed to evaluate ARBs to see whether there is a more specific role in preventing joint stiffness in certain patient subpopulations following TKA.

Active surveillance (AS) of thyroid cancer with serial ultrasounds is a newer management option in the United States.

This work aimed to understand factors associated with the adoption of AS.

We surveyed endocrinologists and surgeons in the American Medical Association Masterfile. To estimate adoption, respondents recommended treatment for 2 hypothetical cases appropriate for AS. Established models of guideline implementation guided questionnaire development. Outcome measures included adoption of AS (nonadopters vs adopters, who respectively did not recommend or recommended AS at least once; and partial vs full adopters, who respectively recommended AS for one or both cases).

The 464 respondents (33.3% response) demographically represented specialties that treat thyroid cancer. Nonadopters (45.7%) were significantly (P < .001) less likely than adopters to practice in academic settings, see more than 25 thyroid cancer patients/year, be aware of AS, use applicable guidelines (P = .04), know how to determine whether a patient is appropriate for AS, have resources to perform AS, or be motivated to use AS.
