Risk Factors for Persistent Opioid Use after Bunion Surgery
OrthoBuzz has previously reported on studies examining the narcotic-prescribing patterns of foot and ankle surgeons. New findings published by Finney et al. in the April 17, 2019 issue of The Journal of Bone & Joint Surgery strongly suggest that the single most powerful and modifiable risk factor for persistent opioid use after bunion surgery was the opioid dose perioperatively prescribed by the surgeon.
The authors analyzed a US private-insurance database to identify >36,500 opioid-naïve patients (mean age, 49 years; 88% female) who underwent one of three surgical bunion treatments. Among those patients, the rate of new persistent opioid use (defined as filling an opioid prescription between 91 and 180 days after the surgery) was 6.2%, or >2,200 individuals. The authors found that patients who underwent a first metatarsal-cuneiform arthrodesis were more likely to have new persistent opioid use, compared with those who received a distal metatarsal osteotomy, which was the most common procedure performed in this cohort. Additional findings included the following:
- Patients who filled an opioid prescription prior to surgery were more likely to continue to use opioids beyond 90 days after surgery.
- Patients who resided in regions outside the Northeastern US demonstrated significantly higher rates of new persistent opioid use.
- The presence of medical comorbidities, preexisting mental health diagnoses, and substance-use disorders were associated with significantly higher new persistent opioid use.
However, physician prescribing patterns had the biggest influence on new persistent opioid use. A total prescribed perioperative opioid dose of >337.5 mg (equivalent to approximately 45 tablets of 5-mg oxycodone) was the major modifiable risk factor for persistent opioid use in this cohort. The authors also pointed out that 45 tablets of 5-mg oxycodone “is a relatively low amount when compared with common orthopaedic prescribing patterns” (see related JBJS study).
As orthopaedic surgeons in all subspecialties rethink their narcotic-analgesic prescribing habits, they should remember that regional anesthesia and non-opiate oral pain-management protocols have had a positive impact on pain management while minimizing narcotic use. The smallest dose of opioids for the shortest period of time seems to be a good rule of thumb.
Are We Overprescribing Opiates to Some Pediatric Patients?
How much opioid analgesia do pediatric patients need after closed reduction and percutaneous pinning of a supracondylar humeral fracture? Not as much as they are being prescribed, suggests a study of 81 kids (mean age of 6 years) by Nelson et al. in the January 16, 2019 issue of The Journal of Bone & Joint Surgery.
All patients in the study underwent closed reduction and percutaneous pinning at a single pediatric trauma center. The authors collected opioid utilization data and pain scores (using the Wong-Baker FACES scale) for postoperative days 1 to 7, 10, 14, and 21 via a text-message system, with automated text queries sent to the phones of the parents/guardians of the patients. (Click here for another January 16, 2019 JBJS study that relied on text messaging.)
Not surprisingly, the mean postoperative pain ratings were highest on the morning of postoperative day 1, but even those were only 3.5 out of a possible 10. By postop day 3, the mean pain rating decreased to <2. As you’d expect, postoperative opioid use decreased in parallel to reported pain.
Overall, patients used only 24% of the opioids they were prescribed after surgery. (See related OrthoBuzz post about the discrepancy between opioids prescribed and their actual use by patients.) Considering that pain levels and opioid usage decreased in this patient population to clinically unimportant levels by postoperative day 3, the authors conclude that “opioid prescriptions containing only 7 doses would be sufficient for the majority of [pediatric] patients after closed reduction and percutaneous pinning without compromising analgesia.”
Now that some normative data such as these are available, Nelson et al. “encourage orthopaedic surgeons treating these common [pediatric] injuries to reflect on their opioid-prescribing practices.” They also call for prospective randomized studies into whether non-narcotic analgesia might be as effective as opioid analgesia for these patients.
Education, Guidelines, Willingness: Keys to Changing Opioid-Prescribing Habits
When planning for any type of surgical procedure, the orthopaedist considers many patient and injury-specific variables. With a distal radius fracture, for example, the main goal of the surgery—anatomic reconstruction of the distal radius—remains constant. However, there are numerous other variables (fracture morphology and patient age, just to name 2) that have to be considered to achieve that goal. Yet, when it comes to postoperative pain control, I imagine that most orthopaedic surgeons prescribe the same amount of opioids to almost every patient undergoing an open reduction/internal fixation of a distal radius fracture, regardless of unique patient characteristics. Our medical mantra that “no two patients are the same” seems to fall by the wayside when it comes to postoperative pain control.
This disconnect is what I thought about while reading the article by Stepan et al. in the January 2, 2019 issue of The Journal. The authors’ institution developed and disseminated to all prescribers a 1-hour opioid education program and consensus-based postoperative opioid prescription guidelines. They then compared the number of opioid pills and total oral morphine equivalents prescribed after 9 ambulatory procedures within 3 subspecialty services (sports medicine, hand, and foot and ankle) prior to and after implementation of the guidelines. Stepan et al. found a significant decrease in the amount of narcotics prescribed after 6 of the 9 surgery types after implementation of the guidelines. Over the course of a year, those decreases would have equaled about 30,000 fewer opioid pills!
Interestingly, there was no significant post-guideline decrease in opioid prescribing after any of the 3 foot-and-ankle procedures. The authors attribute that finding to the slow adoption of the guidelines due to adherence to previously developed pain-management recommendations in this subspecialty.
It has become apparent that we tend to overprescribe opioids postoperatively (see related OrthoBuzz post). This study supports previous data showing that prescription guidelines can be useful in decreasing the amount of postoperative narcotics prescribed to patients, while maintaining adequate pain management and good levels of patient satisfaction. While further work in developing educational tools and procedure-specific “standards” to help surgeons guide their postoperative prescribing practices would be useful, a surgeon’s mindfulness is equally important. We need first to recognize that orthopaedic surgeons tend to overprescribe postoperative opioids—and second, we must be willing to change our habits. Without both awareness and willingness, the best guidelines and recommendations will be ignored, and an opportunity for us to help curb the opioid crisis in our country will be wasted.

What’s New in Orthopaedic Rehabilitation 2018
Every month, JBJS publishes a Specialty Update—a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all OrthoBuzz Specialty Update summaries.
This month, Nitin Jain, MD, MSPH, a co-author of the November 21, 2018 Specialty Update on Orthopaedic Rehabilitation, summarized the most clinically compelling findings from among the more than 40 noteworthy studies summarized in the article.
Acute Pain Management
–A randomized double-blind study comparing 4 two-way combinations of analgesics (three of which contained an opioid medication)1 in emergency-department patients experiencing acute extremity pain found no significant between-group differences in mean pain scores at 1 and 2 hours after medication administration.
Total Hip Arthroplasty
–A randomized clinical trial of >100 patients who underwent unilateral total hip arthroplasty found no significant differences in functional outcomes between a group that participated after surgery in a self-directed home exercise program and a group that participated in a standardized physical therapy program.
Concussion
–An assessment of brain tissue from 202 American football players2 whose organs were donated for neuropathological evaluation found that 87% had evidence of chronic traumatic encephalopathy (CTE). Analysis of brain tissue from former NFL players in the cohort showed that nearly all had severe CTE.
Rotator Cuff Tears
–A study following the natural progression of full-thickness, asymptomatic, degenerative rotator cuff tears found that patients with fatty muscle degeneration were more likely to experience tear-size progression than those without fatty infiltration.
Low Back Pain
–A study consolidating data from 3 separate randomized trials attempted to evaluate the efficacy of radiofrequency (RF) neurotomy for treating a heterogeneous collection of diagnoses that commonly result in low back pain.3 No significant or clinically important differences were found when the RF procedure was compared with a standardized exercise program. The number needed to treat for all 3 arms of the study ranged from 4 to 8, with a median of 5. Some have called into question the methods of this study, particularly the diagnostic criteria used for patient inclusion and the potential inaccuracy of lumping together heterogeneous diagnoses.

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.
Prescribing Opioids: Smallest Dose for Shortest Time
Some people are tired of reading and hearing about the opioid crisis in America. When this topic comes up at meetings, there are rumblings in the crowd. When it’s brought up during hospital safety briefings, there are not-so-subtle eye-rolls, and occasionally I hear frank assertions of “enough already” when new information on the topic appears in the literature. Yet, as two studies in the July 18, 2018 edition of JBJS highlight, this topic is not going away any time soon. And for good reason. We are only starting to scratch the surface of the serious unintended consequences—beyond the risk of addiction—from overly aggressive prescribing and consumption of narcotics.
The first article, by Zhu et al., directly addresses the topic of overprescribing by doctors in China. The authors evaluated how many opioid pills were given to patients who sustained fractures that were treated nonoperatively. The mean number of opioid pills patients reported consuming (7.2) was less than half the mean number prescribed (14.7). More than 70% of patients did not consume all the opioid pills they were prescribed, and 10% of patients consumed no opioids at all. Zhu et al. conclude that “if opioids are used [in this setting], surgeons should prescribe the smallest dose for the shortest time after considering the injury location and type of fracture or dislocation.”
The second article, by Weick et al., underscores the patient-outcome and societal impact of opioid use prior to total hip and knee arthroplasty. Patients from North America who consumed opioids for 60+ days prior to their joint replacement had a significantly increased risk of revision at both the 1-year and 3-year postoperative follow-ups, compared to similar patients who were opioid-naïve before surgery. Similarly, patients who used opioids for 60+ days prior to undergoing a total hip or knee arthroplasty had a significantly increased risk of 30-day readmission, compared to patients who were opioid-naïve. All these differences held when the authors made adjustments for patient age, sex, and comorbidities—meaning that tens of thousands of patients each year can expect to have worse outcomes (and add a large cost burden to the health care system) simply by being on opioid medications for two months preoperatively.
These articles address two very different research questions in two very different regions of the world, but they help expose the chasm in our knowledge surrounding opioid use and misuse. We have been prescribing patients more narcotics than they need while just starting to recognize the importance of minimizing opioid use preoperatively in an effort to maximize surgical outcomes. These two competing impulses emphasize why further opioid-related studies are important. While continuing to look at the negative effects these medications can have on patients, we have to take a hard look at our contribution to the problem.

What’s New in Hand and Wrist Surgery 2018
Every month, JBJS publishes a Specialty Update—a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all OrthoBuzz Specialty Update summaries.
This month, Sanjeev Kakar, MD, author of the March 21, 2018 Specialty Update on Hand and Wrist Surgery, selected the five most clinically compelling findings from among the nearly 40 studies summarized in the Specialty Update.
Distal Radius Fractures
—When can a patient safely drive after surgical treatment of a distal radial fracture? According to a prospective study by Jones et al.1, most patients can do so within 3 weeks following surgery. Twenty-three patients had their driving evaluated 2 and 4 weeks after volar plating. Sixteen of the 23 patients drove safely on a closed course with both hands on their first attempt, which averaged 18 days after surgery.
Scaphoid Fractures
—One factor contributing to scaphoid nonunion is impaired vascularity. So, if the proximal pole of the scaphoid is avascular, is the use of vascularized bone grafting mandatory? No, according to a prospective study by Rancy et al.2, which followed 35 scaphoid nonunion patients treated with curettage, nonvascularized bone grafting, and headless screw fixation. Nine of 23 proximal pole fractures demonstrated ischemia on MRI imaging; 28 of 33 were found to have impaired intraoperative punctate bleeding; and 18 patients had ≥50% tissue necrosis on pathological analysis. CT analysis revealed that 33 of the 35 scaphoids had healed by three months, leading the authors to conclude that nonvascularized bone grafting can suffice as long as the fracture is appropriately reduced and stabilized.
Kienbock Disease
—Lichtman et al.3 introduced a new algorithm for Kienbock disease management that incorporates previous classification systems plus 5 treatment-guiding questions:
- How old is the patient?
- What is the effect of the disease on the lunate?
- How does the disease affect the wrist?
- What treatments are available?
- What are the patient’s requirements?
Depending on the answers, the authors present treatment options ranging from lunate reconstruction to wrist salvage.
Ulnar Impaction
—Some surgeons view radiographic evidence of a reverse oblique inclination in the sigmoid notch as a contraindication for ulnar shortening in patients with ulnar impaction. However, using MRI, Ross et al.4 noted that reverse oblique inclinations of the distal radioulnar joint, as seen on plain radiographs, were not evident when coronal MRI scans were analyzed. They concluded that some patients previously thought to have contraindications to ulnar shortening may in fact be suitable candidates for that procedure.
Prescribing Opioids
—Dwyer et al.5 evaluated an opioid-reduction strategy for patients undergoing carpal tunnel release or volar locking-plate fixation of distal radius fractures. Patients received education and encouragement to use over-the-counter (OTC) medications along with opioids. Among the carpal tunnel cohort (n = 121), the average opioid prescription was for 10 pills compared with 22 in the previous year. Average actual consumption was 3 opioid pills and 11 OTC pills. In the distal radius fracture group (n = 24), the average opioid prescription was 25 pills compared with 39 the year before. These patients consumed on average 16 opioid pills with 20 OTC pills. Patient satisfaction was high in both groups. The authors recommend that physicians prescribe 5 to 10 opioid pills for carpal tunnel release and 20 to 30 pills after volar plating for distal radius fractures.

This month, Chad A. Krueger, MD, JBJS Deputy Editor for Social Media, selected the most clinically compelling findings from among the more than 150 studies cited in the January 17, 2018 Specialty Update on Adult Reconstructive Knee Surgery.
Nonoperative Knee OA Treatment
—Intra-articular corticosteroid injections are commonly administered to mitigate pain and inflammation in knee osteoarthritis (OA). However, a randomized controlled trial of 140 patients found that 2 years of triamcinolone injections, when compared with saline injections, resulted in a significantly greater degree of cartilage loss without significant differences in symptoms.1
Non-Arthroplasty Operative Management
—Knee arthroscopy continues to be largely ineffective for pain relief and functional improvement in knee OA. A randomized controlled trial found no evidence that debridement of unstable chondral flaps found at the time of arthroscopic meniscectomy improves clinical outcomes.
—Cartilage restoration procedures continue to show varying degrees of success. Long-term results from a randomized trial demonstrated no significant differences in joint survivorship and function between patients undergoing microfracture versus autologous chondrocyte implantation (ACI) at 15 years of follow-up. Nearly 50% of patients in both groups had radiographic evidence of early knee OA.
Periprosthetic Joint Infection
—Periprosthetic joint infection (PJI) remains a leading cause of failure following total knee arthroplasty (TKA). Successful treatment requires accurate diagnosis, and alpha-defensin was found to be both sensitive and specific in the diagnosis of PJI. However, it was not significantly superior to leukocyte esterase (LE) in cases of obvious infection.
—Reported rates of reinfection after 2-stage reimplantation for treatment of a first PJI can be as high as 19%. A 3-month course of oral antibiotics following 2-stage procedures significantly improved infection-free survival without complications.2
Post-TKA Complications from Opioids
—Amid ongoing concerns about opioid misuse, two studies3 suggested that preoperative opioid use was found to be an independent predictor of increased length of stay, complications, readmissions, and less pain relief following TKA.
