A Paean to Shoulder Pioneer Doug Harryman
The June 7, 2017 issue of JBJS contains one more in a series of personal essays where orthopaedic clinicians tell a story about a high-impact experience they had that altered their worldview, enhanced them personally, and positively affected the care they provide as orthopaedic physicians.
This “What’s Important” piece comes from Dr. Frederick A. Matsen, III of the University of Washington. In his moving tribute to former colleague Doug Harryman, Dr. Matsen explains how his friend and mentor’s devotion to improving patient outcomes was matched by an unwavering faith that permeated every aspect of his life. The article includes a link to a series of engaging videos that Dr. Harryman made to share his many discoveries about shoulder function with the world.
If you would like JBJS to consider your “What’s Important” story for publication, please submit a manuscript via Editorial Manager. When asked to select an article type, please choose Orthopaedic Forum and include “What’s Important:” at the beginning of the title.
Because they are personal in nature, “What’s Important” submissions will not be subject to the usual stringent JBJS peer-review process. Instead, they will be reviewed by the Editor-in-Chief, who will correspond with the author if revisions are necessary and make the final decision regarding acceptance.

Fracture Liaison Service Boosts Patient Engagement with Secondary Prevention
OrthoBuzz has published several posts about osteoporosis, fragility fractures, and secondary fracture prevention. In the May 17, 2017 edition of JBJS, Bogoch et al. add to evidence suggesting that a coordinator-based fracture liaison service (FLS) improves engagement with secondary-prevention practices among inpatients and outpatients with a fragility fracture.
The Division of Orthopaedic Surgery at the University of Toronto initiated a coordinator-based FLS in 2002 to educate patients with a fragility fracture and refer them for BMD testing and management, including pharmacotherapy if appropriate. Bogoch et al. analyzed key clinical outcomes from 2002 to 2013 among a cohort of 2,191 patients who were not undergoing pharmacotherapy when they initially presented with a fragility fracture.
- Eighty-four percent of inpatients and 85% of outpatients completed BMD tests as recommended.
- Eighty-five percent of inpatients and 79% of outpatients who were referred to follow-up bone health management were assessed by a specialist or primary care physician.
- Among those who attended the referral appointment, 73% of inpatients and 52% of outpatients received a prescription for anti-osteoporosis medication.
The authors conclude that “a coordinator-based fracture liaison service, with an engaged group of orthopaedic surgeons and consultants…achieved a relatively high rate of patient investigation and pharmacotherapy for patients with a fragility fracture.”
Humeral Stem Retention in Revision Shoulder Arthroplasty
Shoulder surgery for complex conditions such as irreparably large rotator cuff tears has been revolutionized by the concept of reverse total shoulder arthroplasty (rTSA). Improved design of rTSA implants by multiple manufacturers has resulted in excellent functional outcomes from these procedures. I have been educated by my shoulder colleagues to the fact that primary rTSA is actually technically less demanding than primary anatomic TSA because of greater exposure of the scapula/ glenoid anatomy.
When anatomic TSA clinically and/or radiographically fails, conversion to rTSA is an alternate to revision anatomic TSA. However, the more expensive and complex rTSA system can be difficult to implant in the revision scenario. In the May 3, 2017 issue of The Journal, Crosby et al. provide the outcomes of conversion from primary anatomic TSA to revision rTSA among two groups: those who originally received a convertible-platform implant system, allowing the humeral stem to be retained during revision, and those whose revision required humeral stem exchange.
Patients with retained-stem revisions had significantly shorter operative times, lower estimated blood loss, lower intraoperative complication rates, and slightly better postoperative ROM. Although the authors caution that “the presence of a convertible-platform humeral component does not guarantee that it can be retained,” they conclude that the data from this study “support the use of a convertible-platform humeral stem when performing primary shoulder arthroplasty.”
Whenever possible, it’s a good idea to design implants where the portions that remain well-fixed can be retained and re-used for the rare revision situation. Such retained, modular parts can save resources, reduce operative time and patient morbidity, and may improve functional outcomes. However, we must be aware that issues with wear debris that have surfaced in modular hip components may also come into play with modular shoulder components.

JBJS/JSES Webinar–Rotator Cuff Tears: On Whom Should We Operate?
The prevalence of rotator-cuff tears is reported to be as high as 30% in people over the age of 60 years. Yet there is still no clear consensus on the indications for surgical treatment of these tears.
On Wednesday, May 24, 2017 at 7:00 PM EDT, The Journal of Bone & Joint Surgery (JBJS) and the Journal of Shoulder and Elbow Surgery (JSES) will host a complimentary* webinar that presents findings from two recently published Level I studies of rotator-cuff tears.
- John Kuhn, MD, discusses findings from a prospective multicenter cohort study in JSES that identifies the characteristics with the greatest influence over whether patients choose surgery for a chronic, symptomatic, full-thickness rotator cuff tear.
- Stefan Moosmayer, MD, reports results from a randomized controlled trial in JBJS that found interesting clinical-outcome differences between physiotherapy alone and tendon repair in patients with tears ≤3 cm.
This webinar is co-moderated by Andrew Green, MD, JBJS deputy editor and chief of the Division of Shoulder and Elbow Surgery at the Warren Alpert Medical School of Brown University and Bill Mallon, MD, past-president of the American Shoulder and Elbow Surgeons (ASES) and editor-in-chief of the Journal of Shoulder and Elbow Surgery (JSES). The webinar will offer additional perspectives on the authors’ presentations from two rotator-cuff experts—Lawrence Higgins, MD and Leesa Galatz, MD. The last 15 minutes will be devoted to a live Q&A session, during which the audience can ask questions of all four panelists.
Seats are limited, so register now!
*This webinar is complimentary for those who attend the event live.
Ambulatory Shoulder Arthroplasty Is Safe
In the April 19, 2017 issue of The Journal, Cancienne et al. compare complication and readmission rates for patients undergoing ambulatory shoulder arthroplasty with those among patients admitted as hospital inpatients postoperatively. Because the analysis was based on data from a large national insurer, we can be quite sure of appropriate coding and accurate data capture.
Similar to our recent report regarding outpatient hand and elbow surgery, in no instance were complications present at a significantly higher rate in the patients who underwent ambulatory shoulder arthroplasty, and the rate of hospital readmission after discharge was not significantly different at 30 or 90 days between the two cohorts.
This definitely is a tip of the hat to orthopaedic surgeons, nurses, and anesthesiologists, who are making sound decisions regarding which patients are appropriate for outpatient arthroplasty. Cancienne et al. found that obesity and morbid obesity were significant demographic risk factors for readmission among the ambulatory cohort, and they also identified the following comorbidities as readmission risk factors in that group:
- Diabetes
- Peripheral vascular disease
- Congestive heart failure
- Chronic lung disease
- Depression
- Chronic anemia
These results offer further documentation regarding the shift away from hospital-based care after orthopaedic surgery. Those of us who perform surgery in dedicated orthopaedic centers as well as general hospital operating rooms understand the concepts of efficiency, focus, maintenance of team skills, and limiting waste. Those objectives in large part drive the move to outpatient surgery. But patients, who almost always prefer to be at home and sleep in their own beds (or recliners in the case of shoulder replacement), may be an even more powerful driver of ambulatory care in the future.
Major advances in postoperative pain management are great enablers in this regard, and I believe the trend will continue. I envision a day when the only patients admitted to hospitals after orthopaedic surgery are those with unstable medical issues who potentially may need ICU care postoperatively.

After Shoulder Arthroplasty, Interscalene Block Results in Rebound Pain
Anecdotally, many patients experience extreme discomfort after shoulder surgery. The April 5, 2017 issue of JBJS features results from a randomized controlled trial comparing morphine consumption and pain during the 24 hours following shoulder arthroplasty among two groups. One group (n=78) received a preoperative interscalene brachial plexus blockade, while the other (n=78) received intraoperative infiltration of bupivacaine liposome suspension.
Mean total postoperative narcotic consumption during the 24 hours after surgery was not significantly different between the two groups, although intraoperative narcotic consumption was significantly lower in the blockade group. The mean VAS pain scores were significantly lower in the blockade group at 0 and 8 hours postoperatively, the same as in the infiltration group at 16 hours postoperatively, and significantly higher than those in the infiltration group at 24 hours postoperatively. That last finding in patients undergoing blockade represents the phenomenon known as “rebound pain.”
The authors, Namdari et al., conclude that the “optimal postoperative pain regimen for shoulder arthroplasty…require[s] further investigation.” But their analysis uncovered four demographic factors that were associated with higher pain scores at 24 hours after surgery, regardless of the analgesic technique used:
- Younger age
- History of depression
- Higher Charlson Comorbidity Score
- Higher preoperative VAS score
In his commentary on the study, Ranjan Gupta, MD notes that one downside of the block approach is “an inability to assess the patient’s neurologic function after the surgical procedure.” His own early clinical experience leads him to favor the admittedly “laborious” infiltration approach, partly because “both patients and orthopaedic nurses who take care of these patients in the immediate postoperative time period can readily appreciate the lack of rebound pain.”
Reverse TSA Components Are Durable, But Patient Outcomes Decline Over a Decade
Reverse total shoulder arthroplasty (RTSA) has yielded promising medium-term outcomes, but what about longer-term results? In the March 15, 2017 edition of The Journal, Bacle et al. look at patient outcomes, prosthetic survival, and complications after a mean follow up of 12.5 years.
The good-news finding from this study was that the overall prosthetic survival rate (using revision as the end point) was 93%, confirming the reliability of the Grammont-style prosthesis. Time, however, took its toll on other outcomes. For example, both mean and absolute Constant scores among the cohort decreased significantly compared with the scores at the medium-term follow up (a minimum of 2 years). The cumulative long-term complication rate was 29%, with 10 of the 47 complications occurring at a mean of 8.3 years. Seven of those 10 delayed complications were attributed to mechanical loosening.
The authors suggest that the deterioration of RTSA outcomes seen in this study “is probably related to patient aging coupled with bone erosion and/or deltoid impairment over time.” They conclude that long-term RTSA outcomes “may be impacted by both the etiology of the shoulder dysfunction and the time since implantation.”

Charles Neer II , a true pioneer in shoulder surgery, coined the term “cuff-tear arthropathy” in 1977. In a landmark 1983 JBJS publication, Dr. Neer, with coauthors Craig and Fukuda (both of whom became internationally recognized experts in shoulder surgery), reported on the pathophysiology and treatment of this previously little-recognized condition that was associated with long-standing massive rotator cuff tears.
Neer’s early work with total shoulder arthroplasty, also reported in JBJS, included a small cohort of patients with cuff-tear arthropathy. In the 1983 article on cuff-tear arthropathy, Neer and his coauthors described the pathologic presentation and treatment with total shoulder arthroplasty, along with a proposed pathophysiologic mechanism. They noted that, although it was a difficult procedure, their preferred treatment was “total shoulder replacement with rotator cuff reconstruction and special rehabilitation.”
Between 1975 and 1983, they surgically treated only 26 patients. Others later recognized that total shoulder replacement was associated with early glenoid failure and recommended treatment with humeral hemiarthroplasty.1 With either approach, success was limited by rotator cuff deficiency and dysfunction. The results were variable, with a small proportion having good outcomes and others achieving some pain relief and limited functional improvement.
Although it was not the first attempt at a reverse shoulder arthroplasty (RSA), Grammont developed an innovative design with improved implant technology and biomechanics to treat massive rotator cuff tears.2 This solved the biomechanical problem that resulted from a deficient rotator cuff and forever revolutionized the care of cuff-deficient shoulders. The Delta 3 prosthesis became available in Europe in the early 1990s but was not widely available in the US until 2004, when it was approved by the FDA.
Initially developed, approved, and used exclusively for cuff-tear arthropathy, early clinical success led to utilization for other conditions with deficient or dysfunctional rotator cuffs, including pseudoparalysis, revision shoulder arthroplasty, acute proximal humerus fractures, fracture sequelae, and chronic glenohumeral dislocations. The results have been so good that the indications have expanded beyond the initial recommendations for use only in elderly low-demand patients. Initial concerns were mollified by the apparent longevity and reported survivorship. Subsequently, there has been such a huge increase in utilization that RSA is approaching 50 percent of the US market share and some of the international market. The implications of expanded indications and increased utilization are yet to be seen.
In 1983, Neer and coauthors reported on what was then a relatively uncommon degenerative condition of the shoulder. Today, rotator cuff-deficient shoulders are much more common and can be better treated due to advances in our understanding of the pathophysiology and biomechanics of the condition, as well as advances in shoulder arthroplasty technology.

New RCT Data on Midshaft Clavicular Fractures
The debate continues as to whether midshaft clavicular fractures are optimally treated surgically or nonoperatively. More data about this clinical dilemma is delivered in the January 18, 2017 issue of JBJS, where Woltz et al. report findings from a multicenter controlled trial that randomized 160 clavicular-fracture patients to receive ORIF with a plate or nonoperative treatment with a sling and physical therapy.
The rate of radiographic nonunion was significantly higher in the nonoperatively treated group after 1 year, but no difference was found between the groups with respect to Constant and DASH scores at any time point—6 weeks, three months, and 1 year. Pain scores and general physical health were marginally better after operative treatment, but only at 6 weeks. However, the rate of second operations for adverse events in the ORIF group was considerable, and after 1 year, implant removal was performed in or scheduled for 16.7% of the operatively treated patients.
Based on these findings and other recent data, the authors “do not advocate routine operative treatment for displaced midshaft clavicular fractures,” although they say early plate fixation may offer advantages for patients who have high demands, high pain scores, or a strong preference for surgery. Based on the fact that “neither treatment option is clearly superior for all patients,” the authors conclude that “the clavicular fracture is preemninently suitable for shared treatment decision-making.”
