Intraoperative radiographic examination is an important step while assessing implant size, including the height of the prosthetic radial head.

Since no single method is perfect on its own, the surgeon should combine as many reference measures as possible, both before and during the procedure, for accurate prosthesis sizing in order to achieve successful outcomes.

With the increasing availability of large clinical registries and administrative data sets, observational (i.e., nonexperimental) orthopaedic research is being performed with increased frequency. While this research substantially advances our field, there are fundamental limitations to what can be determined through a single observational study. Avoiding overstatements and misstatements is important for the sake of accuracy, particularly for ensuring that clinical care is not inadvertently swayed by how an observational study is written up and described. We have noticed that causal language is frequently misused in observational orthopaedic research-that is, language that says or implies that 1 variable definitively causes another, despite the fact that causation can generally only be determined with randomization. In this data-backed commentary, we examine the prevalence of causal language in a random sample of 400 observational orthopaedic studies; we found that causal language was misused in 60% of them.ion.

Although outcome studies generally demonstrate the superiority of a total shoulder arthroplasty (TSA) over a hemiarthroplasty (HA), comparative cost-effectiveness has not been well studied. From a publicly funded health-care system's perspective, this study compared the costs and quality-adjusted life-years (QALYs) in patients who underwent TSA with those in patients who underwent HA.

We conducted a cost-utility analysis using a Markov model to simulate the costs and QALYs for patients undergoing either TSA or HA over a lifetime horizon to account for costs and medically important events over the patient lifetime. Subgroup analyses by age groups (≤50 or >50 years) were performed. A series of sensitivity analyses were performed to assess robustness of study findings. The results were presented in 2019 U.S. dollars.

TSA was dominant as it was less costly ($115,785 compared with $118,501) and more effective (10.21 compared with 8.47 QALYs) than HA over a lifetime horizon. Changes to health utility values after TSA and HA had the largest impact on the cost-effectiveness findings. At a willingness-to-pay (WTP) threshold of $50,000 per QALY gained, HA was not found to be cost-effective. The probability that TSA was cost-effective was 100%.

Based on a WTP of $50,000 per QALY gained, from the perspective of Canada's publicly funded health-care system, TSA was found to be cost-effective in all patients, including those ≤50 years of age, compared with HA.

Topical pharmacological agents typically used to treat postoperative sore throat (POST) after tracheal intubation include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, lidocaine, Glycyrrhiza (licorice), and N-methyl-d-aspartate (NMDA) receptor antagonists (including ketamine and magnesium). However, the optimal prophylactic drug remains elusive.

The literature published before September 8, 2019 was searched on the PubMed, the Embase, the Web of Science, and the Cochrane Library. Randomized controlled trials (RCTs) covering topical prophylactic medications for patients with POST were included. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the quality of evidence. The primary outcome is the risk of POST. Combining both direct and indirect evidence, a network meta-analysis was performed to assess odds ratios (ORs) between the topical pharmacological agents and surface under the cumulative ranking (SUCRA) curve for the treatment-based ouals studied, all of which can be chosen according to the clinical experience of the anesthesiologists and the patient preferences and are recommended for the reduction of postoperative throat pain.

We report a rare variant of sternoclavicular joint (SCJ) dislocation, namely locked anterior-inferior dislocation, with unique clinical, radiographic, and intraoperative findings. In this variant, the medial clavicle was displaced anteriorly and inferiorly and locked in the manubrial-intercostal space, with corresponding mechanical dysfunction of the ipsilateral shoulder girdle joints. Symptoms unique to this variant included painful neck spasms and limited glenohumeral elevation. Nonsurgical treatment was not successful, and open reduction and ligament reconstruction resulted in correction of the fixed deformity with resolution of the clinical symptoms.

Locked anterior-inferior SCJ dislocation is indicated for early open reduction and ligament reconstruction.

Preoperative goals of care (GOC) and code status (CS) discussions are important in achieving an in-depth understanding of the patient's care goals in the setting of a serious illness, enabling the clinician to ensure patient autonomy and shared decision making. Past studies have shown that anesthesiologists are not formally trained in leading these discussions and may lack the necessary skill set. We created an innovative online video curriculum designed to teach these skills. This curriculum was compared to a traditional method of learning from reading the medical literature.

In this bi-institutional randomized controlled trial at 2 major academic medical centers, 60 anesthesiology trainees were randomized to receive the educational content in 1 of 2 formats (1) the novel video curriculum (video group) or (2) journal articles (reading group). Thirty residents were assigned to the experimental video curriculum group, and 30 were assigned to the reading group. The content incorporated into the 2 formats focused on general preoperative evaluation of patients and communication strategies pertaining to GOC and CS discussions.
