Physician groups and hospitals have come to rely on electronic patient portals (EPPs) for many things, including appointment scheduling and reminders, delivery of test results, and pre- and post-visit information gathering from patients. Most of the research into the clinical efficacy and cost-effectiveness of EPPs has taken place in primary care and internal medicine settings. But in the August 5, 2020 issue of The Journal of Bone & Joint Surgery, Varady et al. examine the benefits of EPP use among patients undergoing orthopaedic procedures of various types. In the process, they also uncover racial and socioeconomic disparities in the use of EPPs.
The retrospective review of >18,000 patients (average age of 56.9 years) undergoing an orthopaedic procedure at 2 Boston-area academic hospitals found a veritable 50-50 split between those who used the EPP and those who did not. Relative to white patients, African-American and Hispanic patients were significantly less likely to use the EPP. Other demographic factors associated with portal nonuse were non-English speaking, male sex, low income, and having less than a college education.
Multivariable regression analysis demonstrated that, relative to EPP nonuse, EPP use was associated with significantly lower no-show rates, increased odds of completing one or more patient-reported outcome measures (PROMs), and improved overall patient satisfaction. The degree of after-surgery functional improvements measured with PROMs was the same among EPP users and nonusers.
The authors home in on the benefits of the 27% reduction in missed appointments this study divulged. First and foremost, missed appointments have been shown to negatively affect patient outcomes. On the provider side, no-shows increase staff frustration and cost time and money. (The 2 hospitals realized a combined estimated $200,000 in savings over 1 year from the reduction in no-shows.) Consequently, Varady et al. say that “the benefit of reducing missed appointments alone may be sufficiently strong to warrant efforts to increase EPP enrollment.”
Increased efforts among orthopaedic office staff and clinicians to enroll patients in portal usage during their hospital stay or during pre- or postoperative visits could also help address the disparity issue. “These results have important implications for the orthopaedic surgery community in…achieving more equitable care,” the authors conclude.

Hip fractures are an important cause of morbidity and mortality among the elderly population worldwide. However, age-adjusted hip fracture incidence has decreased in the US over the last 2 decades. While many attribute the decline to improved osteoporosis treatment, the definitive cause remains unknown. A population-based cohort study of participants in the Framingham Heart Study prospectively followed a cohort of >10,000 patients for the first hip fracture between 1970 and 2010.
The age-adjusted incidence of hip fracture decreased by 4.4% per year during this study period. That decrease in hip fracture incidence was coincident with a decrease over those same 4 decades in rates of smoking (from 38% in 1970 to 15% by 2010) and heavy drinking (from 7% to 4.5%), with subjects born more recently having a lower incidence of hip fracture for a given age. Meanwhile, during the study period, the prevalence of other hip-fracture risk factors–such as being underweight, being obese, and experiencing early menopause–remained stable.
This study’s findings should be interpreted in light of 2 major limitations. First of all, there was a lack of contemporaneous bone mineral density data across the study period; secondly, all the study subjects were white. Nevertheless, these findings should encourage physicians to continue carefully managing patients who have osteoporosis and at the same time caution them against smoking and heavy drinking.

Patient-reported outcome measures (PROMs) have become increasingly important tools in the 30 years since the orthopaedic community began embracing the movement toward the “patient perspective.” Clinical findings such as range of motion and imaging results remain important, but we have come to understand that pain and function–as reported by the patient–are the most crucial data points. And we are not alone. Insurance companies, registries, scholarly publications, and research review panels now often require PROMs as part of their core evaluations.
But not all PROMs are created equal. For clinicians to trust the output from these instruments, validation of the measures is required. This entails reliability testing and assessment of face, construct, and criterion validity. Furthermore, translating PROMs validated in English into other languages involves not only linguistic translation, but also cultural components in order to capture the full patient perspective.
In the August 5, 2020 issue of The Journal, Bin Sheeha et al. report their work in evaluating the responsiveness, reliability, and validity of the Arabic-language version of the Oxford Knee Score (OKS-Ar). After painstaking statistical analysis of OKS-Ar questionnaires completed by 100 Arabic-speaking patients (80 of whom were female) before and after total knee arthroplasty (TKA), the authors concluded that the OKS-Ar is a valid, sensitive, and easy-to-use instrument to assess pain and function in TKA-treated individuals whose main language is Arabic.
To be truthful, this is not very glamorous research to conduct or very exciting to read about. However, it is absolutely fundamental to ensuring the validity of multicenter, international trials and registry studies. In essence, Bin Sheeha et al. have dug a conduit that facilitates the flow of reliable data and that will help improve future patient care worldwide. As such, it deserves our attention, understanding, and appreciation.

Approximately 20% of patients who undergo spine surgery have osteoporosis, which has a significant impact on spine-surgery complications such as failure of fixation devices and collapse fractures following fusion procedures. In a recent critical analysis review, authors focus on improving outcomes by identifying and optimizing patients with osteoporosis prior to spine surgery. The multidisciplinary team involved in that process should include primary care providers, endocrinologists, physical therapists, and orthopaedic surgeons.
The predominant tool for assessing bone mineral density (BMD) is dual x-ray absorptiometry. The diagnosis is based on a T score, which represents the number of standard deviations between the patient’s BMD and that of a healthy 30-year-old woman. Standard deviations ≤─2.5 define osteoporosis. The Z score is similar to the T score but compares the patient to an age- and sex-matched individual.
A history of low-energy fracture, such as a wrist fracture following a fall from a standing height, is considered a sentinel event for suspicion of fragility fractures. The combination of a fragility fracture and low BMD is considered to be severe osteoporosis. The most common form of osteoporosis is associated with a postmenopausal decrease in mineralization, but there are other causes. These include advanced kidney disease, hypogonadism, Cushing disease, vitamin D deficiency, anorexia and/or bulimia, rheumatoid arthritis, hyperthyroidism, primary hyperparathyroidism, and some medications (e.g., anticonvulsants, corticosteroids, heparin, and proton pump inhibitors).
Forty-seven percent of patients undergoing spine deformity surgery and 64% of cervical spine surgery patients have low vitamin D levels. Postoperative bone health can be enhanced in women ≥51 years old with daily intake of 800 to 1,000 units of vitamin D and 1,200 mg of daily calcium. There is no solid evidence that pre- or postoperative bisphosphonates have a positive impact on bone healing. Conversely, some series have shown that teriparatide, an anabolic parathyroid hormone, may improve time-to-fusion and help reduce screw pull-out after lumbar fusion in postmenopausal women.
Calcitonin has been shown to reduce the incidence of vertebral compression fracture, but there is no concrete evidence that it supports spine-fusion healing. Similarly, there is no strong evidence for the use of estrogen or selective estrogen receptor modulators in this surgical scenario. There is evidence that when the human monoclonal antibody denosumab is combined with teriparatide, spine-fusion healing may be improved relative to the use of teriparatide alone. Finally, the review article identifies screw size, screw position, and other surgical considerations that can improve fixation strength.
Using the “Own the Bone” practices promulgated by the American Orthopaedic Association and the technical considerations described in this review, we should be able to mitigate osteoporosis-related postoperative complications in spine-surgery patients.

This month, Thomas K. Fehring, MD, co-author of the July 15, 2020 “What’s New in Musculoskeletal Infection,” selected the five most clinically compelling findings—all focused on periprosthetic joint infection (PJI)—from among the more than 80 noteworthy studies summarized in the article.
–A retrospective case-control study1 found that patients who received an allogeneic blood transfusion during or after knee or hip replacement had a higher risk of PJI than those who were not transfused.
–A retrospective review2 found that using inflammatory markers to diagnose PJI in immunosuppressed joint-replacement patients is not suitable and that newly described thresholds for synovial cell count and differential have better operative characteristics.
–A retrospective review3 of a 2-stage debridement protocol with component retention in 83 joint-replacement patients showed an 86.7% success rate of infection control at an average follow-up of 41 months.
–A single-center study4 of perioperative antibiotic selection for patients undergoing total joint arthroplasty found that the risk of PJI was 32% lower among those who received cefazolin compared with those who received other antimicrobial agents. The findings emphasize the importance of preoperative allergy testing in patients with stated beta-lactam allergies.
–A review of regional and state antibiograms5 showed that 75% of methicillin-sensitive S. aureus (MSSA) isolates and 60% of both methicillin-resistant S. aureus (MRSA) and coagulase-negative Staphylococcus isolates were susceptible to clindamycin, whereas 99% of all isolates were susceptible to vancomycin.

Since 2016, The Journal of Bone & Joint Surgery and JBJS Journal of Orthopaedics for Physician Assistants (JOPA) have awarded two $500 prizes to outstanding JOPA review articles or case studies written by authors who were PA students at the time of article submission.
The 2019 award winners for best articles by PA students produced high-quality literature reviews that address current and impactful topics. We recognized author Matthew Morrow, BA, PA-S out of Northwestern University for “The Effects of Cannabinoid Use on Acute Orthopaedic Pain: A Review of the Current Literature,” which showed that cannabis use provided little to no pain relief for acute musculoskeletal pain. The review also concluded that cannabis use while recovering from musculoskeletal trauma may be associated with an increased use of narcotics. The article suggests that cannabis use has a larger role for chronic rather than acute musculoskeletal pain.
Brittany Szabo, PA-S and Justin Gambini, MSPAS, PA-C, from Campbell University College of Pharmacy and Health Sciences, were recognized for “Ewing Sarcoma: A Review on Primary Bone Malignancy in Pediatrics and the Diagnosis, Treatment, and Challenges of Managing Ewing Sarcoma.” This article provided a comprehensive review of a “can’t miss” orthopaedic diagnosis, including clinical and diagnostic signs for orthopaedic providers to look for.
Congratulations to our 2019 PA student writing-award winners! We are offering two $500 awards again this year, so please encourage all of your PA students to submit an article for consideration! Deadline for submission is December 31, 2020.
And be on the lookout for an announcement about 2 additional 2019 JOPA Writing Award winners.

OrthoBuzz occasionally receives posts from guest bloggers. This guest post comes from Adam Bitterman, DO in response to 2 recent articles in the July 15, 2020 issue of The Journal of Bone & Joint Surgery.
The United States continues to struggle in the grip of the global COVID-19 pandemic. Certain regions within the US are experiencing a sharply increased COVID-19 case volume, while other locales have stabilized their disease burden. But overall, the country’s healthcare system and economy remain under stress.
Healthcare systems in regions that don’t have high COVID-19 burdens have begun to provide their full list of services, of which elective orthopaedic surgery is one. However, amid concern about a “second wave” of the pandemic, the reemergence of elective orthopedic surgery must be made–and monitored–in the context of public health. Now more than ever, surgeons and their patients must consider how individual patient-centered decisions might play out in the public domain.
As Anoushiravani and colleagues point out, the return of elective orthopedic surgery should be based in large part on the COVID-19 burden in any given geographic location. Local jurisdictions must regulate the return to “normalcy” according to measurements that gauge activity of the virus, such as the number of new diagnoses and hospitalizations and the percent occupancy of ICU beds. In another JBJS article on this topic, Parvizi et al. emphasize that local hospitals and health systems need to weigh resumption of elective orthopaedic procedures also against staffing capability and available supplies of PPE and ventilators. The sensible recommendations from both sets of authors emphasize the importance of ascertaining local disease patterns in order to provide appropriate and safe care for all patients.
The new “normal” in healthcare is a moving target that requires fluidity and flexibility to make frequent reassessments. The economic disruption caused by the pandemic may take years to resolve, and economics is another factor in these resuming-surgery equations. As members of the healthcare team, it is imperative that we focus on the well-being of our patients, surgical team and staff, and our local community. We all must be vigilant for signs of resurgence of the disease. And, please, wear a mask whenever you are out in public and social distancing is not feasible.

Many animal studies have investigated the impact of nonselective NSAIDs and selective COX-2 inhibitors on fracture healing. Nearly all those experiments focused on chronic drug administration following simulated long-bone fractures. One concern regarding the clinical relevance of those animal studies is that the “fractures” are often created by open means, which results in cortical devascularization and which may not accurately simulate the most common long-bone fracture pathophysiology in humans. Nevertheless, many orthopaedic surgeons have used the results of those animal studies to limit—or even stop—their use of NSAIDs to treat postfracture pain.
In the July 15, 2020 issue of The Journal, George et al. use a large private-insurance database to investigate the association between postfracture prescriptions filled for NSAIDS (both selective COX-2 inhibitors and nonselective types) and the subsequent diagnosis of a nonunion at 1 year postinjury. Administrative database research is more useful for generating hypotheses than for proving or disproving them, and these authors (along with Commentary writer Willem-Jan Metsemakers, MD, PhD) rightly point out that adequately powered randomized trials are needed to more fully address this issue.
Still, I was a bit surprised by the finding that nonselective NSAIDs were not associated with the diagnosis of nonunion while selective COX-2 inhibitors were. It seems to me that, given the sparse and conflicting clinical evidence today, a brief course of NSAIDs for fracture-related pain management should be included for patients while we await answers from studies with more robust research designs.

Acetabular components for primary total hip arthroplasty (THA) made with ultraporous surfaces were developed to enhance osseointegration and biological fixation. In the July 1, 2020 issue of The Journal of Bone & Joint Surgery, Palomaki et al. report on a registry study that suggests that implant survival with these components over an average follow-up of 3.6 years is not so “ultra.”
The authors evaluated >6,000 primary THAs that used a Tritanium ultraporous cup and >25,000 THAs that used a conventional cup, all performed between 2009 and 2017. When they compared the two groups for revision for any reason, the 5-year Kaplan-Meier survivorship of the Tritanium group (94.7%) was inferior to that of the conventional-cup group (96.0%). When revision for aseptic loosening was examined, the 5-year survivorship was also inferior for the Tritanium group (99.0%) compared with the conventional group (99.9%). Regression analysis revealed that the Tritanium group had a much higher risk of revision for aseptic loosening 2 to 4 years after surgery (hazard ratio, 11.2; p <0.001). Interestingly, these survivorship and risk-of-revision differences disappeared when the authors analyzed data for the period from May 15, 2014 to December 31, 2017–when the registry was updated to include patient BMI and ASA-class data.
The authors cite several caveats that readers should apply to these findings. The registry did not capture radiographic findings for these patients, so potentially relevant imaging data could not be analyzed. And, despite the database upgrade in 2014, there was a dearth of available data on patient comorbidities. Finally, wide confidence intervals for some of the hazard-ratio calculations suggest the need to confirm revision-risk findings with further research.
Limitations notwithstanding, the study by Palomaki et al. suggests that the performance of ultraporous cups may not meet the hopes and expectations of hip surgeons and their patients.
