New Frontiers in Journal Clubs
Depending on which historical account you read, journal clubs have been a staple of medical education since around 1875. Still ubiquitous within medical education today, journal clubs help educators and students alike stay current on medical literature, provide a vehicle for teaching how to critically appraise medical studies, and convene a forum in which respectful debate can occur among colleagues. Journal clubs constitute a medical-education practice that almost no one questions, probably because they are so effective.
But that doesn’t mean journal clubs can’t be improved. As the September 30, 2018 deadline approaches to submit applications for the JBJS Robert Bucholz Journal Club Grant Program (click here for the application form), I encourage medical-education leaders to envision new ways in which journal clubs could further orthopaedic education. That might include various iterations of “virtual” journal clubs over the internet. For example, the Journal of Hand Surgery recently hosted a journal club on Twitter. Another intriguing possibility would be to invite authors of journal articles with conflicting conclusions about the same research question to discuss their findings in a point/counterpoint format over teleconference. (Today’s teleconferencing platforms are not hard to set up, are relatively low-cost, and could broaden journal-club participation to anyone with a suitable device and a high-speed internet connection.)
The traditional face-to-face journal club provides many unique benefits, but creating new, innovative platforms for using departmental or grant-based journal-club funds could increase their impact and help ensure the sustainability of these educational programs. It will also be important for everyone to share their experiences with alternative journal-club formats. It behooves the orthopaedic community to continually envision how to integrate the journal-club component of medical education into new technologies as they evolve.

JBJS 100: Bankart Repair, Carpal Tunnel Assessment
Under one name or another, The Journal of Bone & Joint Surgery has published quality orthopaedic content spanning three centuries. In 1919, our publication was called the Journal of Orthopaedic Surgery, and the first volume of that journal was Volume 1 of what we know today as JBJS.
Thus, the 24 issues we turn out in 2018 will constitute our 100th volume. To help celebrate this milestone, throughout the year we will be spotlighting 100 of the most influential JBJS articles on OrthoBuzz, making the original content openly accessible for a limited time.
Unlike the scientific rigor of Journal content, the selection of this list was not entirely scientific. About half we picked from “JBJS Classics,” which were chosen previously by current and past JBJS Editors-in-Chief and Deputy Editors. We also selected JBJS articles that have been cited more than 1,000 times in other publications, according to Google Scholar search results. Finally, we considered “activity” on the Web of Science and The Journal’s websites.
We hope you enjoy and benefit from reading these groundbreaking articles from JBJS, as we mark our 100th volume. Here are two more:
The Bankart Procedure: A Long-Term End-Result Study
C R Rowe, D Patel, W W Southmayd: JBJS, 1978 January; 60 (1): 1
This was the first large clinical series with long follow-up to report the findings and results of the open Bankart repair. The results were almost uniformly excellent or good, and this study contributed to the demise of nonanatomic shoulder repairs.
A Self-Administered Questionnaire for the Assessment of Severity of Symptoms and Functional Status in Carpal Tunnel Syndrome
D W Levine, B P Simmons, M J Koris, L H Daltroy, G G Hohl, A H Fossel, J N Katz: JBJS, 1993 January; 75 (11): 1585
Distinguishing interventions that work from those that don’t requires rigorous outcomes research, which, in turn, relies on standardized, patient-centered measures that have proven reliability and validity. Meeting these criteria are the Symptom Severity and Functional Status Scales for carpal tunnel syndrome described in this oft-cited JBJS study from 25 years ago.
Sept. 11 Webinar – Assessment of Bone Health for the Orthopaedic Surgeon
Orthopaedic care teams can play an active role in evaluating and optimizing their patients’ bone health to help prevent primary and secondary fragility fractures and to improve postsurgical outcomes. In just about any orthopaedic scenario, helping patients optimize their bone health is an imperative for the delivery of quality care.
On Tuesday, September 11, 2018 at 8 pm EDT, the American Orthopaedic Association (AOA) and The Journal of Bone & Joint Surgery (JBJS) will host a complimentary one-hour webinar that will cover the basics of a bone-health assessment by orthopaedists.
- Christopher Shuhart, MD will discuss the fundamentals of bone-related laboratory workups and bone densitometry studies.
- Joe Lane, MD, FAOA will identify bone-health “red flags” in orthopaedic patients, including common nutritional deficiencies.
- Paul Anderson, MD, FAOA will cover recent advances in bone-density measurements.
Moderated by Douglas Lundy, MD, MBA, FAOA, orthopaedic trauma surgeon at Resurgens Orthopaedics, this webinar will include a 15-minute live Q&A session during which attendees can ask questions of the panelists.

Opioid-Tapering Plan May Help Prevent Prolonged Use after Trauma/Surgery
Addressing the opioid epidemic requires a concerted effort from all sectors of society, but the role of surgeons (orthopaedic and otherwise) cannot be ignored because they determine how best to manage postoperative pain for millions of patients. OrthoBuzz recently commented on two opioid-related studies from the July 18, 2018 issue of JBJS. In the August 1, 2018 edition of The Journal, Mohamadi et al. explain findings from a meta-analysis of 37 studies involving nearly 2 million patients that pinpoint several patient-related risk factors associated with opioid use beyond 2 months following surgery or trauma.
Using careful meta-analysis methods, the authors determined that about 4% of patients continued to use prescription opioids beyond 2 months after surgery or trauma. They also identified the following risk factors as being “among the most important predictors of prolonged opioid use” in these patients:
- Prior use of opioids or benzodiazepines
- Depression
- Long-duration hospital stay
- History of back pain
Mohamadi et al. also calculated a “number needed to harm” (NNH) from their data. NNH indicates the number of patients with a certain risk factor that is necessary to result in 1 person with prolonged opioid use beyond that of a patient population without that risk factor. They found that for every 3 patients with a history of opioid use, every 23 patients with a history of back pain, every 40 with depression, or every 62 with a history of benzodiazepine use, 1 patient will continue to use prescribed opioids for an extended time period.
Because this meta-analysis was derived from observational studies, the authors caution that “causal inferences could not be drawn for the proposed risk factors.” But they do offer a practical piece of advice gleaned from prior research: Provide patients with an opioid-tapering plan at the time of discharge to significantly reduce the likelihood of prolonged opioid use.
August 2018 Article Exchange with JOSPT
In 2015, JBJS launched an “article exchange” collaboration with the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) to support multidisciplinary integration, continuity of care, and excellent patient outcomes in orthopaedics and sports medicine.
During the month of August 2018, JBJS and OrthoBuzz readers will have open access to the JOSPT article titled “Impact of Risk Adjustment on Provider Ranking for Patients With Low Back Pain Receiving Physical Therapy.”
The authors’ findings confirmed their hypothesis that robust risk adjustment is essential for objective comparison of patient-reported outcomes and for accurately reflecting quality of care among patients treated for low back pain.
New Patient-Outcomes Data Hint at Benefits from Computer-Navigated TKA
Like the vast majority of orthopaedic surgeons, I do not use computer navigation for total knee arthroplasties (TKAs). My hospital does not own the equipment, I have not asked for it, and I feel confident in the outcomes for my patients using current conventional techniques. Moreover, we have not had published data suggesting that using computerized navigation actually improves the one thing we care most about: patient outcomes. However, the two-year data presented by Petursson et al. in the August 1, 2018 issue of JBJS may represent a tipping point.
The authors report on 2-year results from a double-blind, prospective randomized trial evaluating outcomes in 167 patients following TKAs performed using conventional techniques or computer-guided navigation. Both patients and observing radiologists/physical therapists were blinded to the technique used.
Among the many patient-reported measures used to compare 2-year outcomes, the authors found that scores for 3 subscales favored the computer-navigation group. Specifically, the symptom and sports-and-recreation subscales of the KOOS and the stiffness subscale of the WOMAC showed significantly greater improvements in the group that underwent computer-navigated TKA. These results led Petursson et al. to conclude that TKAs completed with the assistance of computer navigation provided better pain relief and function at two years postoperatively.
These are important findings, as this is one of the largest randomized, double-blind analyses comparing computer navigation versus conventional TKA. While previous studies had found computer navigation to be useful in terms of obtaining neutral mechanical alignment, data showing improved patient outcomes was either lacking or revealed no clinically important between-group differences. These 2-year data suggest that this is no longer the case. However, it is important to note that the study does not explicitly state whether patients were still blinded to their treatment at the time when the 2-year follow-up data was collected. If they were no longer blinded at that point of follow-up, the results would need to be viewed from a more tempered perspective.
Either way, it is important to note that in this study—as in previous research investigating similar questions—TKAs completed using conventional techniques also yielded large improvements in patient-reported outcomes. Still, because patients and surgeons alike continue to be intrigued by the possibilities that technological advances in arthroplasty may offer, studies like this are vital.

More Evidence of Patient Benefits with Cross-Linked Polyethylene
In an OrthoBuzz post last year titled “Has Conventional Polyethylene Become Obsolete?,” we featured results from a small randomized trial that documented much-improved implant survival over 10 years with acetabular components made from cross-linked polyethylene (XLPE) compared with conventional polyethylene (CPE). In the August 1, 2018 issue of The Journal, we find further corroboration of the benefits realized by patients who receive XLPE acetabular components.
deSteiger et al. analyzed registry data involving more than 240,000 total hip arthroplasty (THA) patients and found markedly lower revision rates in those who received XPLE rather than CPE acetabular components. At a mean follow-up of 16 years, the cumulative percentage of revisions was 6.2% in the XPLE group versus 11.7% in the CPE group. Among patients <55 years of age at the time of THA, at 7 years there was a five-fold increase in revision rates for procedures done with CPE compared to those done with XLPE.
Because the authors observed that the between-group differences in revision rates became more pronounced over time, it is possible that this difference will continue to grow as more data is gathered. When we consider the vast number of THAs performed around the world each year, this XLPE-related decrease in revision rate could have a beneficial impact on millions of patients.
The documented success so far of XPLE is a clear case where understanding the nature of the original problem (polyethylene wear) and applying consistent and innovative research to find a solution have allowed patients worldwide to reap the benefits associated with THA, with some assurance that their hip replacement may, in fact, last for their rest of their life.

Displaced Proximal Humeral Fractures: Classification and Evaluation
C Neer: JBJS, 1970 September; 52 (6): 1077
Complex distal humeral fractures have long challenged orthopaedic surgeons and their patients. Often the first step in fracture-management decision-making is classification, and in this 1970 study, Dr. Neer proposed a 6-group classification based on the presence or absence of displacement of one or more of the four major proximal segments. Since then, this classification has been variably adapted by multiple authors, but its usefulness remains intact.
The Effect of Implants Loaded with Autologous Mesenchymal Stem Cells on the Healing of Canine Segmental Bone Defects
S F Bruder, K H Kraus, V M Goldberg, S Kadiyala: JBJS, 1998 July; 80 (7): 985
Research into mesenchymal stem cells (MSCs) to augment healing of tendons, chondral and bone defects, and other connective tissues has taken off since these authors used autologous MSCs to help heal 21-mm segmental femoral defects. Radiographic union occurred rapidly at the interface between host bone and porous ceramic cylinders loaded with MSCs, and a large collar of bone had formed around the cell-loaded implants after 16 weeks.
