Home in on Bone Health in Patients with Fragility Fractures

AOA_OwnTheBone_Logo_12.17_Final_RGB-stackedOrthoBuzz occasionally receives posts from guest bloggers. This guest post comes from James Blair, MD, in response to a recent edition of the OrthoJOE podcast.

Geriatric hip fractures are among the fastest growing subset of injuries that orthopaedic surgeons treat. Often these injuries are the first objective signs of osteoporosis. While the surgical treatment of these fractures continues to improve, orthopaedic surgeons may be neglecting their role in triggering investigations into the underlying bone health of these patients.

A recent insurance database analysis by Sara Cromer, MD, presented at the Endocrine Society’s 2021 Annual Meeting, demonstrated a substantial drop in the use of bone-directed medications over the past decade, despite the rise in the number of osteoporotic-related fractures. It is unclear why this trend has occurred, but the main concern is that new diagnoses of osteoporosis are being overlooked.

This concern arose during a recent OrthoJOE podcast focused on distal radial fractures. OrthoEvidence Editor-in-Chief Dr. Mo Bhandari alluded to the confusion over who is responsible for bone-health intervention during treatment of a fragility fracture: the inpatient orthopaedic surgery team, the hospitalist, or the patient’s family physician or internist. “The thought is that someone is going to manage this,” Dr. Bhandari states. “Everyone is looking at everyone else, and it’s not happening.”

In fragility-fracture cases, JBJS Editor-in-Chief Dr. Marc Swiontkowski emphasized the importance of orthopaedic surgeons initiating investigations into their patients’ bone quality with evaluations of vitamin D, ionized calcium, and parathyroid and thyroid hormone levels. “We are failing miserably at this,” Dr. Swiontkowski laments, recalling seeing 3 elderly patients in a single day with a hip fracture that was preceded by a distal radial fracture a decade earlier–with no bone-health investigation ever performed at that time.

Initiatives like the American Orthopaedic Association’s (AOA’s) “Own The Bone” program try to raise awareness of our broader responsibility as orthopaedic surgeons when treating osteoporotic fractures such as those of the proximal femur, distal radius, and vertebrae. Drs. Bhandari and Swiontkowski strongly believe that the orthopaedic surgeon must claim ownership of their patients’ bone health, not necessarily by medically managing such cases, but by initiating a dialog with the patient’s primary care physician and/or rheumatologist/endocrinologist.

What’s New in Hand and Wrist Surgery 2021

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 14 specialty areas. Click here for a collection of all such OrthoBuzz Guest Editorial summaries.

This month, author Christopher J. Dy, MD, MPH summarizes the 5 most compelling findings from the 40 studies highlighted in the most recent “What’s New in Hand and Wrist Surgery.”

Carpal Tunnel Syndrome

–Corticosteroid injection is one modality for managing carpal tunnel syndrome, and a recent study examined the accuracy of needle placement1. Of 756 simulated injections, correct placement was noted for 572 (76%). The needle was placed in the median nerve 66 times (8.7%), and the carpal tunnel was missed 118 times (15.6%). As noted by the study authors, “safety of carpal tunnel injection remains an important concern.”

Cubital Tunnel Syndrome

–One recent study evaluating patient-reported outcomes of in situ decompression for cubital tunnel syndrome found that 66 (86%) of 77 patients were satisfied2. All of the patients who were not satisfied had preoperative weakness of the muscles innervated by the ulnar nerve.

Distal Radial Fracture

–A retrospective radiographic analysis of 273 uninjured adult distal radii found that the volar cortical angle (VCA) ranged from 23° to 43° (mean, 32°)3. With most volar locking plates having a fixed angle of 18° to 30°, there is a strong possibility of a mismatch between the patient’s VCA and the implant. If the patient’s VCA exceeds the implant’s fixed angle, undercorrection of sagittal tilt may result if the plate is used to guide reduction in treating a distal radial fracture.

Dupuytren Contracture

–A recent report presented a single surgeon’s experience over an 11-year time frame with 3 common treatments of Dupuytren contracture4. The rates of reintervention after needle aponeurotomy were 24% at 2 years and 61% at 5 years; after collagenase injection at the same time points, 41% and 55%; and after surgical fasciectomy, 4% at both 2 and 5 years. When factoring in cost, needle aponeurotomy appeared to be a high-value intervention.

Scapholunate Dissociation

–Among 203 patients who underwent  3-ligament tenodesis for scapholunate injury, improvement in patient-reported outcomes at 1 year was noted for 79%, but 10% had no change, and 11% had worse patient-reported outcomes5. Indications for 3-ligament tenodesis may need further clarification.

Surgical-Technique Videos Focus on Pediatric Fractures

Many orthopaedic surgeons who take emergency-department or trauma call are confronted with a pediatric patient presenting with a fracture. However, very few of those orthopaedists are pediatric subspecialists. In fact, Geisinger researchers recently reported that the median number of pediatric orthopaedists per state in the US is only 23 (range 0 to 134).

To address these demographic realities, JBJS Essential Surgical Techniques has launched a video-based, point-of-care resource to help any orthopaedic surgeon manage the most common pediatric fractures with the highest level of quality, helping ensure excellent outcomes for young patients and their parents. Most of the authors of these pediatric-focused procedural videos are members of CORTICES—a collaboration of pediatric orthopedic surgeons dedicated to improving the management of emergent orthopedic conditions through education, research, and development of optimal care guidelines.

Here are links to the 5 already-published video articles in this series:

Upcoming videos in this special series will cover the following 5 topics:

  • Screw Fixation of Pediatric Proximal Tibial Tubercle Fractures
  • Reduction and Internal Screw Fixation of Transitional Ankle Fractures
  • Flexible Intramedullary Nailing of Pediatric Femur Fractures
  • Intramedullary Fixation of the Ulna for Monteggia Fracture Management
  • Open Reduction and Internal Fixation of Pediatric Medial Epicondyle Humerus Fractures

JBJS Essential Surgical Techniques is the premier online journal describing how to perform orthopaedic surgical procedures, verified by evidence-based outcomes, vetted by peer review, and utilizing video to optimize the educational experience, thereby enhancing patient care.

More Data on Managing Distal Radial Fractures in Old Patients

Distal radial fractures are common, especially in the elderly, but the best management for these fractures in older patients remains controversial. Clinical practice guidelines issued in 2011 by the AAOS recommend operative treatment when certain angulation and shortening criteria are met. Meanwhile, some studies show that age >65 years is an independent risk factor for poor radiographic outcomes,1 while other studies suggest that older patients have acceptable functional outcomes despite radiographic loss of reduction.2 We may want to believe that anatomic reduction and normal-appearing radiographs will ensure improved outcomes, but the science has not always confirmed that connection, leaving us and our older patients in a bit of a conundrum.

In the January 2, 2020 issue of The Journal, DeGeorge et al. tackle this subject in a large retrospective analysis of data from patients ≥65 years old who had been managed for a distal radial fracture between 2009 and 2014. Among >13,000 distal radial fractures analyzed, 9,973 were treated nonoperatively and 3,740 were treated operatively. The average age of the entire cohort was 75.4 years, but the authors found that the operative group was significantly younger, and that nonoperative treatment was more commonly performed in patients with a greater number and severity of medical comorbidities, including cardiovascular disease, diabetes, cancer, and dementia.

At 90 days, the overall complication rate was low (36.5 complications per 1,000 fractures), and the authors found no significant differences between the operative and nonoperative groups. However, the complication rate at 1 year was significantly higher in the operative group (307.5 per 1,000 fractures) compared to the nonoperative group (236.2 complications per 1,000 fractures). Stiffness was the most common complication across both groups, but it was significantly more common in the group that underwent operative management (occurring in 16% of that cohort). Also of note: approximately 10% of patients in each group developed chronic regional pain syndrome.

Despite the inherent weaknesses in retrospective database analyses (including, in this case, the inability to analyze indications for surgery), this study reveals some important facts that may help us better counsel older patients. Operative management of distal radial fractures in the elderly may yield better radiographic outcomes than nonoperative treatment, but that comes with a significantly increased risk of 1-year complications. Accepting a less-than-perfect reduction on radiographs and casting the fracture may be more beneficial than surgery for many of our elderly patients.

“Appropriate” Management of Distal Radial Fractures Improves Outcomes, Lowers Cost

Many surgeons realize that to improve value, we must improve the quality of care while decreasing its cost. Clinical Practice Guidelines (CPGs) developed by the AAOS and other medical societies are designed to help improve the quality of care and safety for patients, while also reducing inappropriate care and decreasing cost. Unfortunately, the evidence used for the development of CPGs is often of mixed quality. It is therefore crucial that studies evaluate patient outcomes when clinicians do and do not adhere to CPGs, so we can ensure that the guidelines are achieving their objective of improving care.

In the October 16, 2019 issue of The Journal of Bone and Joint Surgery, Giladi et al. hypothesize that adhering to Recommendation 3 of the AAOS CPG regarding radiographic indications for operative management of distal radial fractures would yield improved patient outcomes and cost benefits. Recommendation 3 of the CPG suggests that fractures with post-reduction radial shortening of >3 mm, dorsal tilt of >10°, or intra-articular displacement or step-off of >2 mm should be operatively treated. The authors retrospectively reviewed 266 patients, 145 of whom were treated operatively and 121 of whom were treated nonoperatively. Based on the guideline recommendation, only 6 patients were determined to have undergone inappropriate operative fixation, but 68 patients in the nonoperative cohort received inappropriate treatment; many of those had higher-grade fractures that, per the guideline, should have been surgically treated.

Using QuickDASH outcome scores at 4 time points up to 1 year and 1-year direct cost data, the authors compared the appropriately treated operative cohort to both the appropriate and inappropriate nonoperative groups. They also compared the appropriate and inappropriate nonoperative groups to each other. QuickDASH outcomes for appropriate nonoperative treatment were better than those for inappropriate nonoperative treatment at 1 year. In addition, inappropriate nonoperative treatment cost 60% more than appropriate nonoperative treatment. Although this cost comparison did not reach statistical significance, (p=0.23), it does  suggest a cost savings with adherence to the CPGs. Appropriately treated operative patients reported less disability than the inappropriately nonoperative group.

As we continue to work at increasing health-care value, it is critical that we review CPGs in action, as Giladi et al. have done in this study.  A potential next step would be to investigate whether the modest improvements in QuickDASH scores noted between appropriate operative treatment and inappropriate nonoperative treatment justify the 6-fold higher cost of operative treatment.

Plate–Tendon Contact: How Important Is It?

There are few things more discouraging for an orthopaedic surgeon than a late postoperative complication after what was an otherwise successful surgery. One such scenario occurs when patients who have undergone open reduction/internal fixation (ORIF) for a distal radial fracture subsequently experience a flexor pollicis longus (FPL) tendon rupture. While previous literature has suggested that plate positioning plays a role in that complication, no studies have evaluated whether newer plate designs decrease contact with the FPL tendon and therefore reduce the risk of rupture.

With that question in mind, Stepan et al. evaluated two cohorts of patients who had undergone ORIF for a distal radial fracture. In the September 4, 2019 issue of JBJS, they report on findings from 40 patients, 20 of whom received a standard distal radial volar locking plate, and 20 of whom received a plate designed with a distal cutout to afford the FPL more room to traverse.

Ultrasound analysis revealed that similar percentages of patients in each group had FPL–plate contact (65% in the FPL-plate group and 79% in the standard-plate group), and there were no differences between groups in terms of FPL tendon degeneration as seen on ultrasound. However, patients who received the FPL plate had significantly less of the tendon come in contact with the plate at 0° and 45° of wrist extension. The authors noted, however, that this difference may have been influenced by the fact that patients with the FPL-specific plate also had significantly lower volar tilt than patients with the standard locking plate. It is therefore not possible to determine whether it was the plate design or the bone position (or both) that led to these results.

It is also noteworthy that the two senior authors of this study work as consultants for the company that manufactures the plates that were evaluated. It is also important to note that because all the patients in this study were asymptomatic, further research is needed to determine the clinical importance of reduced tendon–plate contact area. We should temper our excitement about specially designed volar plates until we have more clinical data supporting their success in avoiding the problem for which they were designed.

How Many X-Rays Does It Take to Treat a Distal Radial Fracture?

We orthopaedists obtain radiographs for many reasons—to diagnose an unknown problem, to determine the progress of healing, and occasionally because we follow X-ray “dogma” acquired over time. That last reason prompted van Gerven et al. to undertake a multicenter, prospective, randomized controlled trial, the findings of which appear in the August 7, 2019 issue of The Journal.

The authors set out to evaluate the clinical utility of radiographs taken after a distal radial fracture in >300 patients. Some of those fractures were treated nonoperatively, while others underwent operative fixation. Surgeons of the patients randomized to the “usual-care” pathway were instructed to obtain radiographs at 1, 2, 6, and 12 weeks following the injury/surgery. Surgeons of patients in the “reduced-imaging” arm did not obtain radiographs beyond 2 weeks after the injury/surgery unless there was a specific clinical reason for doing so.

The authors found no significant differences between groups in any of the 6 patient-reported outcomes measured in the study, including the DASH score. Furthermore, the complication rates were almost identical between the usual-care (11.4%) and reduced-imaging (11.3%) groups. Not surprisingly, patients in the reduced-imaging group had fewer radiographs obtained (median 3 vs 4) and were exposed to a lower overall dose of ionizing radiation than those in the usual-care group.

Probably because the study was conducted in the Netherlands, it did not address the widespread practice of “defensive medicine” in the US—the unnecessary overuse of medical tests and procedures to reduce the risk of a malpractice claim. While that may limit the external validity of these findings among orthopaedists in the United States, this relatively simple yet well-designed study should remind us that it is important to have a definite clinical purpose when ordering a test of any type. A picture may be worth a thousand words, but sometimes it takes only 2 pictures to tell the full story of a healing distal radial fracture.

What’s New in Hand Surgery 2019

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in one of 13 subspecialties. Click here for a collection of all OrthoBuzz subspecialty summaries.

This month, Christopher J. Dy, MD, MPH, author of the March 20, 2019 “What’s New in Hand Surgery,” selected the five most compelling findings from among the 47 noteworthy studies summarized in the article.

Distal Radial Fractures
—A randomized trial comparing volar plate fixation to cast management in patients >60 years of age who had AO type-C distal radial fractures1 found that the volar plating group had better Patient-Rated Wrist Evaluation scores than the casting group after a minimum 24 months of follow-up. Maintenance of reduction was also better in the volar plating group. These findings are contrary to those of a similar randomized trial published in 2011, suggesting that there are patient-level and surgeon-level differences between the 2 environments in which the studies were conducted.

—Among 175 elderly patients with distal radial fractures treated nonoperatively and who showed acceptable radiographic reduction at 1 to 2 weeks, 28% had late displacement or malunion at the 3-month follow-up.2 Relative to cases in which reduction was maintained, cases with late displacement or malunion had lower grip strength and loss of the total wrist range of motion. However, there was no between-group difference in patient-reported functional measures, and the incidence of the most common complication—carpal tunnel syndrome—was the same in both groups.

Scaphoid Fractures
—Findings from a biomechanical study with cadavers suggest that 50% cortical healing of a scaphoid fracture after open reduction and internal fixation with a compression screw is sufficient to allow unrestricted activity.3 Constructs with a 50% osteotomy and compression screw showed the same load to failure as intact scaphoids, but load to failure in a group with a 75% osteotomy and compression screw was lower than that in the intact scaphoid group.

—Traditionally, surgeons have emphasized proximal pole vascularity in cases of scaphoid nonunion. However, a study of 35 scaphoid nonunions treated with nonvascularized bone grafting and a headless compression screw4 found that 33 fractures went on to union, despite evidence of compromised proximal pole vascularity in 14 of 32 patients who had histopathological data available.

Carpal Tunnel Syndrome
—A cross-sectional study analyzing data from 367 patients who presented for evaluation of carpal tunnel syndrome (CTS)5 found that those with the poorest socioeconomic status had worse PROMIS scores for physical function, pain interference, depression, and anxiety, compared with those in the least-deprived quartile. Deprived patients were also more likely to have a higher comorbidity burden and to use tobacco, both of which may influence outcomes after CTS treatment.

What’s New in Pediatric Orthopaedics 2019

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in one of 13 subspecialties. Click here for a collection of all OrthoBuzz subspecialty summaries.

This month, Kelly L. VanderHave, MD, co-author of the February 20, 2019 “What’s New in Pediatric Orthopaedics,” selected the five most compelling findings from among the more than 50 noteworthy studies summarized in the article.

Pediatric Trauma
—A before-and-after comparison found that, after implementation of a dedicated, weekday operating room reserved for pediatric trauma, length of stay for 5 common pediatric orthopaedic fractures was reduced by >5 hours. In addition, cost was reduced by about $1,200 per patient; complication rates improved slightly; frequency of after-hours surgery decreased by 48%; and wait times for surgery were significantly reduced.

—Forty-two patients with a distal radial buckle fracture received a removable wrist brace during an initial clinic visit, along with instructions to wear it for 3 to 4 weeks. No follow-up was scheduled, but the family was contacted at 1 week and at 5 to 10 months following treatment. No complications or refractures occurred; 100% of respondents said they would select the same treatment.1

Pediatric Sports Medicine
—Among a continuous cohort of 85 patients (mean age 13.9 years) who underwent primary ACL reconstruction (77% with open physes at time of surgery) and who were followed for a  minimum of 2 years, overall prevalence of a second ACL surgery was 32%, including 16 ACL graft ruptures and 11 contralateral ACL tears. A slower return to sport was found to be protective against a second ACL injury.

Infection and Scoliosis Surgery
—A preliminary study of 36 pediatric patients who underwent a total of 191 procedures for early-onset scoliosis found that the use of vancomycin powder during closure significantly decreased the rate of surgical site infection (13.8% per procedure in the control group versus 4.8% per procedure in the vancomycin group).

Clubfoot
—A retrospective review of >1,100 clubfeet that were presumed to be idiopathic upon presentation found that the condition in 112 feet (8.9%) was later determined to be associated with neurological, syndromic, chromosomal, or spinal abnormalities—and therefore nonidiopathic.2 The nonidiopathic group was less likely to have a good result at the 2- and 5-year follow-up, and more likely to require surgery. The authors conclude, however, that surgery is avoidable for most patients with nonidiopathic clubfoot.
