Risk Factors for Infection After Distal Radius Fracture Fixation: Analysis of Impact on Cost of Care

Cannabis Use in Patients With Distal Radius Fractures: A Moment of Unity?

BACKGROUND

As legalization of cannabis spreads, an increasing number of patients who use cannabis are being seen in the clinical setting. This study examined the impact of cannabis and tobacco use on postoperative complications following open reduction and internal fixation (ORIF) of distal radius fractures.

METHODS

A national, all-payer database was queried to identify patients who underwent ORIF of a distal radius fracture between 2015 and 2020 (n = 970 747). Patients were stratified into the following groups: (1) tobacco use (n = 86 941), (2) cannabis use (n = 898), (3) tobacco and cannabis use (n = 9842), and (4) neither tobacco nor cannabis use ("control", 747 892). Multivariable logistic regression was used to identify risk factors for infection, nonunion, and malunion within the first postoperative year.

RESULTS

Concomitant use of tobacco and cannabis was associated with a higher rate of nonunion (5.0%) compared to tobacco or cannabis use alone (P < .001). Multivariate analysis identified cannabis-only use (odds ratio [OR] 1.25), tobacco-only use (OR 2.17), and concurrent tobacco and cannabis use (OR 1.78) as risk factors for infection within the first postoperative year. Similarly, cannabis-only use (OR 1.47), tobacco-only use (OR 1.92), and concurrent tobacco and cannabis use (OR 2.52) were associated with an increased risk of malunion.

CONCLUSIONS

Cannabis use is associated with an elevated risk of infection and malunion following operative management of a distal radius fracture. Concomitant use of cannabis and tobacco poses an elevated risk of nonunion and malunion compared to tobacco use alone.

Outcomes of Volar Plating Distal Radius Fractures Based on Surgical Timing

BACKGROUND

While complexity of distal radius fractures varies, volar plating is the most prevalent surgical option in adult injuries. The time between date of injury and surgical intervention varies according to several factors, including the timing of presentation and the surgeon's availability. This study aims to understand the impact of a delay in surgical intervention on operative time, patient-reported outcomes, and reoperation rates.

METHODS

A retrospective review was performed on patients treated with volar plating of distal radius fractures from 2017 to 2020 at a single institution by multiple surgeons. Perioperative medical records were reviewed. Patients were divided into 2 groups using a cut-off date of surgery performed 12 days after injury. Descriptive analyses were used to compare demographics, fracture characteristics, operative information, and outcome data including postoperative Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores and reoperation rates between groups.

RESULTS

A total of 257 patients were included. There was no difference in age, gender, smoking status, fracture type, or postoperative QuickDASH scores between groups. Patients fixed at 12 days or more after injury had a higher rate of reoperation, higher American Society of Anesthesiologists scores, and more surgeon experience.

CONCLUSIONS

Volar distal radius fixation at 12 or more days after injury had no discernible differences with fracture type, operative time, or tourniquet time; however, a higher rate of reoperation was found in this group compared to earlier intervention. These data may provide important prognostic information that can be used to educate patients who present in a delayed fashion.

Operative Versus Nonoperative Management of Pyogenic Flexor Tenosynovitis: An Analysis of the National Readmissions Database

Purpose

The purpose of this study was to use a national database to determine if either surgical or nonsurgical management of pyogenic flexor tenosynovitis (PFT) led to specific superior outcomes.

Methods

International Classification of Diseases, Tenth Revision codes were used to identify patients admitted with PFT from the National Readmissions Database for the years 2016-2019. All patients had been admitted initially and treated with either surgical or nonsurgical management. Baseline characteristics were determined, and in those who were readmitted, the top 10 diagnoses of 90-day readmissions were identified. Risk factors for readmission were identified using a regression analysis. Ninety-day readmission rates, amputation rates, and length of stay between the groups were compared, as these are outcomes that can be reviewed from the database.

Results

The overall 90-day readmission rate was 13.25%. Infectious complications from the original diagnosis of PFT were the leading causes of readmission. Variables associated with 90-day readmission were higher Charlson comorbidity index, hypertension, Medicaid insurance, longer initial length of hospital stay, tobacco use, and nonsurgical management. Ninety-day readmission rates and amputation rates were higher in the nonsurgical group.

Conclusions

In patients with PFT, surgical intervention may prevent hospital readmissions and reduce the likelihood of amputation. Readmission is more likely in patients with more medical comorbidities, tobacco users, and lower socioeconomic status.

A qualitative inquiry to explore management of distal radius fracture by certified hand therapists

BACKGROUND

Distal radius fractures (DRF) are extremely common in middle-aged and elderly. Certified Hand Therapists (CHT) are experts in managing hand injuries including DRF.

PURPOSE

Using qualitative methodology, this study examined practice patterns among CHT and understand prevalent common patterns in managing DRF.

STUDY DESIGN

Descriptive qualitative study.

METHODS

This study utilized a qualitative descriptive method with an inductive approach to discern the practices of CHT in managing DRF. A purposive sample of practicing CHT was assembled. A semi-structured interview guide facilitated qualitative interviews using open-ended questions to assess practices of CHT in the domains of assessment, interventions, and appropriateness for discharge. Two student physical therapists transcribed the interviews, which were verified by a third rater for accuracy. Thematic content analysis guided the coding and analyses of the interview data. A two-phase coding process was conducted using Nvivo software. Two study authors developed initial codebook and completed subsequent analysis of transcripts.

RESULTS

Of the 12 participants, five were PT and seven were OT with an average experience of 14.1 years as a CHT. Practice patterns across domains were largely consistent among CHT. All CHTs reported inquiring about severity of displacement of DRF, orthopedic management, comorbidities, and medical history as well as examining wrist/hand range of motion (ROM), grip strength (GS), and wrist functions (n = 12). A large majority administered outcome measures and performed sensory and integumentary assessment. Patient education regarding injury and exercises was the key element for interventions. Adequate gains in GS, wrist functions, wrist ROM, and ability to use wrist/hand for functional tasks were the key benchmarks for discharge from care.

DISCUSSION

Most practice behaviors were common among CHTs while managing DRF. Some variations exist depending whether their primary discipline is PT or OT. The results highlight knowledge-to-action gap, where most CHTs do not integrate fall-risk management in DRF.

CONCLUSIONS

This study identified common practice patterns among CHTs in managing DRF while also identifying opportunity to improve practice by integrating assessment of balance and fall-risk.

Episode-Based Bundled Payments in Hand Surgery: An Affordable Solution to Overwhelming Health Care Costs

The purpose of this review is to examine the literature regarding episode-based bundled payment models for hand surgery. Health care and productivity costs associated with the surgical management of hand and wrist pathologies represent a substantial burden on the United States health care system. Traditional fee-for-service models fail to incentivize interdisciplinary collaboration and optimization of resources. More recently, the concept of episode-based bundled payments has evolved as a potential solution to rising health care costs by encouraging care coordination, streamlining billing processes, and linking reimbursement to quality metrics and patient outcomes as opposed to the volume of services rendered. Although episode-based bundled payments have demonstrated the potential to reduce health care costs in various medical specialties, their feasibility in hand surgery remains relatively unexplored. The transition to episode-based bundled payments in hand surgery hinges on the ability to incentivize physicians to work cohesively with other members of the care team to reduce low-value preoperative testing, optimize patients preoperatively, and establish treatment guidelines, especially for patients undergoing high-volume, low-complexity procedures. By fostering collaboration among stakeholders, leveraging data-driven insights, and prioritizing patient-centered care, episode-based bundled payments have the potential to enhance the value and efficiency of hand surgery services while improving patient outcomes. The current literature regarding episode-based bundled payments in hand surgery highlights various avenues for cost savings, including alternative sites of service, surgical approaches, use of anesthesia, and the elimination of low-value tests, and demonstrates that there is sufficient evidence to proceed to a trial phase for episode-based bundled payments in hand surgery.

Effect of Time to Surgery on Surgical Site Infection in Open Distal Radius Fractures: A Review of the ACS Trauma Quality Improvement Program Database

INTRODUCTION

Managing open distal radius fractures (DRFs) poses challenges. While preventing surgical site infection (SSI) involves prompt antibiotic administration and thorough irrigation and debridement, the impact of urgent intervention on reducing postoperative infection rates is debated. We hypothesize that timing of surgery does not significantly affect the incidence of SSI in open DRF treated within or after 24 hours from time of injury.

METHODS

We retrospectively analyzed the American College of Surgeons Trauma Quality Improvement Program from 2011 to 2021. We focused on outcome variables, including superficial SSI and deep SSI or osteomyelitis. To evaluate the relationship between time to operative intervention and SSI rates, we employed least absolute shrinkage and selection operator and multivariate regression models, adjusting for patient-specific factors and injury severity.

RESULTS

A total of 14 486 patients were included. Regression modeling demonstrated a 23% increase in the odds of deep SSI with each 1-day delay in surgery (P = .010). However, no association was found between time to surgery and superficial SSI (odds ratio [OR] = 0.96, P = .768). Injury severity score (ISS) was associated with increased odds of superficial SSI (OR = 1.06, P < .001) and deep SSI (OR = 1.06, P < .001) while diabetes (OR = 3.56, P = .013) was significantly associated with increased rates of superficial SSI.

CONCLUSIONS

Extended time to surgery correlates with a modest rise in deep SSI incidence in open DRF. However, there was no heightened risk of superficial SSI in patients with delayed surgery. Polytrauma, alcohol use disorder, and diabetes were linked to elevated SSI rates in open DRF.

A Comparison of the Rates of Postoperative Infection Following Distal Radius Fixation Between Pediatric and Young Adult Populations: An Analysis of 32 368 Patients

BACKGROUND

Infection following surgical fixation of a distal radius fracture can markedly compromise a patient's functional outcome. This study aimed to compare infection rates in pediatric (5-14 years) and adolescent (15-17 years) patients undergoing fixation of a distal radius fracture to a cohort of young adult (18-30 years) patients.

METHODS

A matched retrospective study was performed using PearlDiver to determine the rates of postoperative infection following distal radius fixation. χ2 and logistic regression were used to assess differences in rates, while linear regression was used to analyze rates of infection over time.

RESULTS

In 32 368 patients, young adults experienced postoperative infection at a significantly increased rate (odds ratio [OR] = 1.81; 95% confidence interval [CI], 1.45-2.27). This trend was consistent among the male (OR = 1.96; 1.49-2.57) and female (OR = 2.11, 1.37-3.27) cohorts. In the multivariate model, the adult cohort remained at increased risk (OR = 1.40; 95% CI, 1.04-1.89), with open fracture (OR = 4.99; 3.55-6.87), smoking (OR = 1.76; 1.22-2.48), hypertension (OR = 1.69; 1.20-2.33), and obesity (OR = 1.37; 1.02, 1.80) identified as other significant risk factors. There was no significant change in the rate of postoperative infections over the 11-year study period.

CONCLUSION

This study demonstrated that although surgical site infections following distal radius fixation are low in patients aged 30 years or younger (0.97%), young adults develop infections at a significantly increased rate. This is important for surgeons to recognize when counseling patients on the risks of surgical fixation.

Complications of operatively treated distal radial fractures

Distal radial fractures represent the most common fractures of the upper extremity. Operative treatment is performed for approximately one-third of distal radial fractures in the adult population. Complications following operative treatment of distal radial fractures vary depending on the treatment modality and can be stratified into preoperative and postoperative complications. Complications can occur in the near, intermediate and long term. The most common complications seen are tendon irritation and rupture, chronic regional pain syndrome (CRPS), carpal tunnel syndrome, ulnar or radial neuropathy, compartment syndrome, malunion, inadequate fixation or loss of fixation, symptomatic hardware, post-traumatic arthritis, stiffness and infection. Careful planning, treatment and patient selection can help to mitigate these complications.Level of evidence: V.

Analysis of fracture-related infections from Swedish insurance claims between 2011 and 2021

Fracture-related infections (FRI) pose a serious complication with an incidence of 1-2%. This study aimed to analyze compensation claims submitted to The Swedish National Patient Insurance Company (LÖF) because of FRI after closed/open reduction and internal fixation (C/ORIF) in the four most common fracture sites (proximal humerus, distal radius, hip, ankle). Patients registered in the LÖF database with a suspected FRI between 2011 and 2021 were identified by matching International Classification of Diseases and procedural codes indicative of a combination of fractures to the proximal humerus, distal radius, hip and ankle, C/ORIF and infection. Medical records were reviewed for fracture sites, pathogens and complications. Data from the Swedish Fracture Register (SFR) were extracted to estimate the proportion of reported claims to the presumed number of FRI. Of 122 FRI identified in the LÖF database, 34 were after C/ORIF in the proximal humerus, 12 in the distal radius, 28 in the hip and 48 in the ankle. LÖF compensated 111 patients (91%). Median time from C/ORIF to an FRI was 3 weeks (interquartile range 2-6), and 95% of all FRI occurred within 1 year after C/ORIF. Staphylococcus aureus was the most common pathogen in patients with a distal radius, hip and ankle FRI. In contrast, Cutibacterium spp. were the most common aetiology in FRI of the proximal humerus. The total number of fractures treated with C/ORIF in the four fracture sites registered in the SFR during 2021 was 18,711. Most of the FRI patients were diagnosed within the first year after C/ORIF, and 91% of the patients received compensation. Given an expected FRI incidence of 1-2%, our estimates with extrapolated data from the SFR indicate that < 10% of affected patients applied for compensation.

Incidence and risk factors for surgical site infection following volar locking plating (VLP) of unstable distal radius fracture (DRF)

PURPOSE

Volar locking plating (VLP) is the mainstay of treatment for distal radius fracture (DRF) but may be compromised by postoperative surgical site infection (SSI). This study aimed to identify the incidence and the risk factors for SSI following VLP of DRF.

METHODS

This retrospective study identified consecutive patients who underwent VLP for closed unstable DRFs in our institution between January 2015 and June 2021. Postoperative SSI was identified by inquiring the medical records, the follow-up records or the readmission medical records for treatment of SSI. The potential factors for SSI were extracted from the medical records. Univariate and multivariate logistic regression analyses were performed to identify the independent factors.

RESULTS

There were 930 patients included, and 34 had an SSI, representing an incidence of 3.7% (95% CI 2.4-4.9%). Patients with an SSI had threefold extended hospitalization stay (44.1 ± 38.2 versus 14.4 ± 12.5 days) as did those without. In univariate analysis, 18 variables were tested to be statistically different between SSI and non-SSI group. In multivariate analysis, 6 factors were identified as independently associated with SSI, including sex (male vs. female, OR 3.5, p = 0.014), ASA (III and IV vs. I, OR 3.2, p = 0.031), smoking (yes vs. no, OR 2.4, p = 0.015), bone grafting (OR 4.0, p = 0.007), surgeon volume (low vs. high, OR 2.7, p 0.011) and operation at night-time (vs. day-time, OR 7.8, p < 0.001).

CONCLUSION

The postoperative SSI of VLP of DRF was not uncommon, and the factors identified in this study, especially those modifiable, would help identify individual SSI risk, target clinical surveillance and inform patient counseling.

Risk Factors for Complications following Volar Locking Plate (VLP) Fixation of Unstable Distal Radius Fracture (DRF)

Objective

To evaluate the incidence and risk factors for complications following volar locking plate (VLP) fixation of unstable distal radius fracture (DRF).

Methods

This retrospective study identified patients who underwent VLP fixation of unstable DRF between 2017 and 2020 with a minimum 12-month follow-up assessments. By reviewing electronic medical records and follow-up notes, patients were categorized complication or noncomplication group. Differences in variables were detected by using univariate analyses, and independent factors were identified using multivariate logistic regression analysis.

Results

During this study period, 423 patients were included, and 63 (rate, 14.9%) complications in 58 patients were documented. Wound infection (17, 4.0%) was most common, followed in decreasing frequency by carpal tunnel syndrome (13, 3.1%), tendon rupture/irritation (10, 2.4%), complex regional pain syndrome (8, 1.9%), and plate/screw-related complications (5, 1.7%). In the univariate analyses, 18 variables were found to be significantly different (p < 0.05). Logistic regression analysis identified 5 independent factors, including being male (OR, 3.5; p = 0.014), type C fracture (vs. type A, OR: 2.7, and p = 0.035), general anesthesia (vs. regional, OR: 2.4, and p = 0.045), bone grafting (OR, 6.3; p < 0.001), and surgery performed by less experienced surgeons (OR, 3.1; p = 0.003). The goodness-of-fit of the final model was acceptable.

Conclusions

These factors will help surgeons individualize and stratify the risk of complications and help patients for risk counselling; especially, an informed clinical decision targeting those modifiable factors (anesthesia mode, bone grafting, and surgeon experience) can be considered, when indicated.
