Stable rates of operative treatment of distal radius fractures in Ontario, Canada: a population-based retrospective cohort study (2004–2013)

Comparison between Volar Locking Plate and Kirschner Wire Fixation for Unstable Distal Radius Fracture: A Meta-Analysis of Randomized Controlled Trials

Objective  This study aims to compare the outcomes of volar locking plating (VLP) versus percutaneous Kirschner wires (K-wire) fixation for surgical management of unstable distal radius fractures. Methods  We systematically searched multiple databases, including MEDLINE, EMBASE, Cochrane Central till January 2022 for randomized controlled trials (RCTs) that met eligibility criteria. Following outcomes were evaluated at 6-week, 3-, 6-, and 12-month follow-up period: Disabilities of the Arm, Shoulder, and Hand (DASH) score, Patient Rated Wrist Evaluation (PRWE) score, grip strength, range of motion, and complication incidence. Meta-analysis was performed using random effects models and results presented as risk ratios (RRs) or mean differences (MDs) with 95% confidence interval. Results  Fourteen RCTs with 1,450 participants met the inclusion criteria. DASH scores were significantly better for VLP fixation at 6th week (MD = 19.02; p  < 0.001), 3rd (MD = 10.79; p  < 0.001), 6th (MD= 7.78; p  < 0.001), and 12th month (MD = 2.94; p  < 0.001) postoperation. At 3-month follow-up period, VLP treatment exhibited better grip strength (MD = - 10.32; p  < 0.001) and PRWE scores (MD = 8.78; p  < 0.001). There was a statistically significant early advantage in flexion, extension, pronation, supination, radial deviation, and ulnar deviation in the VLP group at 6-week follow-up, but at 1-year follow-up only significantly better extension was observed. At 1 year, radiographic outcomes were similar except for volar tilt favoring VLP fixation ( p  < 0.001). Superficial infections were more common in patients treated with K-wire (RR = 2.89; p  = 0.001), but there was no difference in total complications or reoperation rates ( p  > 0.05). Conclusion  This meta-analysis suggests that VLP fixation and K-wire fixation are both effective procedures, but existing literature does not provide sufficient evidence to demonstrate the superiority of either method. Although VLP fixation improves DASH score, extension and volar tilt at 12-month follow-up, the difference is small and unlikely to be noticeable to the patients.

Intrafocal Pinning in Distal Extraarticular Radius Fracture: A Retrospective Study Based on Patient Age

Background

Percutaneous intrafocal pinning is one of the many surgical options for extraarticular distal radius fracture with minimal comminution. This study aims to describe the role and indications of intrafocal pinning.

Methods

This monocentric, retrospective study included 49 patients who underwent intrafocal pinning for distal radius fractures in 2013 in our French hand surgery department. All the patients underwent posteroanterior and lateral x-ray on days 2 and 45 to measure radial inclination, distal radioulnar index, and volar tilt.

Results

The mean age of the patients was 45.4 years, with women representing approximately 61.2% of the sample (n = 30). The patients were divided into three groups: group A (17-50 y), 26 patients; group B (50-70 y), 15 patients; and group C (>70 y), eight patients. We documented on x-ray images, 21 secondary displacements, including seven in group C. There were three displacements (all in group C) and one surgical revision within 15 days for a previous displacement. The distal radioulnar index increased in all three groups.

Conclusions

The percutaneous intrafocal pinning fixation technique exposes a high risk of complications, especially for those older than 50 years, for whom this technique should be avoided. Overall, due to the frequency of secondary displacements encountered, our first-line treatment favors plate osteosynthesis for all patients. Pinning fixation should only be considered with caution in younger patients if plate osteosynthesis is not possible, but it requires a strict 6-week immobilization. The fracture morphology must also be considered.

Non-surgical vs. surgical treatment of distal radius fractures: a meta-analysis of randomized controlled trials

PURPOSE

To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture.

METHODS

We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS).

RESULTS

There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P < 0.001). And in grip strength (%), the results showed a significant improvement in surgical treatment compared with non-surgical treatment (WMD - 6.60, 95% CI (-11.61, -1.60), P = 0.01). There was significant difference in radial inclination, radial length, volar title, range of wrist pronation, range of wrist supination. However, no difference in radial deviation, ulnar deviation, ulnar variance, range of wrist extension and range of wrist flexion was observed.

CONCLUSIONS

The results of this meta-analysis suggest that some patients with surgical treatment of distal radius fractures not only improved the grip strength (%), decreased the DASH score, but also improved the range of wrist pronation and the range of wrist supination compared with nonsurgical treatment. Based on the present meta-analysis, we suggest that some patients with surgical treatment might be more effective in patients with distal radius fracture.

Time to surgical management of distal radius fractures: effects on health care utilization and functional outcomes

BACKGROUND

Distal radius fractures are common injuries. Open reduction and internal fixation with volar locking plates is the most common approach for surgical fixation. This study investigated the association between time to surgery and health care utilization, income, and functional outcomes among patients undergoing open reduction and internal fixation for distal radius fracture.

METHODS

We conducted a retrospective review of patients who underwent open reduction and internal fixation for isolated acute distal radius fracture between 2009 and 2019. Time to surgery was grouped as early (≤ 14 d) and delayed (> 14 d). We performed χ2 (or Fisher exact) and Wilcoxon rank sum (or Kruskal-Wallis) tests to provide statistical comparison of time to surgery by health care utilization and functional outcomes. Univariable and multivariable logistic regression analyses were performed to identify factors significantly associated with time to surgery. We included all significant univariables in the multivariable logistic regression model, which identified factors based on significant adjusted odds ratios (95% confidence intervals excluding the null) after we adjusted for confounding variables.

RESULTS

We included 106 patients, with 36 (34.0%) in the group receiving early treatment and 70 (66.0%) in the group receiving delayed treatment. Patients in the delayed-treatment group attended significantly more clinic visits and postoperative hand therapy sessions. The group with delayed treatment demonstrated significantly lower degrees of wrist flexion at the first follow-up, but this difference did not persist. Patients with higher estimated income (> $39 405 per annum) had lower odds of delayed surgery than those with lower estimated income (≤ $39 405).

CONCLUSION

Delayed time to surgery was associated with greater health care utilization and lower degrees of early wrist flexion. Access to care for lower-income patients warrants further evaluation.

Understanding Changing Demographic and Treatment Trends of Distal Radius Fractures: A TriNetX Database Contemporary Analysis of 32,912 Patients

Purpose

Distal radius fractures (DRF) are among the most commonly encountered fractures. The population of the United States is rapidly growing, aging, and diversifying. This study was undertaken to better understand current incidences and treatment trends across all ages, gender, and races to inform resource allocation and to potentially address treatment inequities.

Methods

The TriNetX US Collaborative Network was queried for all patients diagnosed with DRFs from 2017 to 2022. Cohorts were defined by inclusion and exclusion of Current Procedural Terminology procedure codes and categorized into operative and nonsurgical groups. Statistical analysis was performed to determine differences in management among demographic groups across the 6-year time period.

Results

Incidence rates of operative intervention for DRF increased from 19.6% in 2017 to 23.6% in 2022. Incidence rates of operative intervention increased from 21.7% to 25.2% for females and from 15.3% to 19.7% for males. A bimodal distribution was observed in females with more fractures occurring in the pediatric and geriatric ages, but this distribution was not observed in males. All demographic groups had an overall higher incidence of nonsurgical intervention. Patients aged 40-64 years were more likely to undergo operative intervention than patients 18-39 years. Females were more likely to undergo operative intervention than males. White patients were more likely to undergo operative intervention than Black patients and Asian patients.

Conclusions

The incidence of DRFs continues to climb, as does their rate of operative management. The classic bimodal distribution was observed in females, but not males. However, differences in management of DRFs were also observed across different demographic groups with ongoing racial disparities. Future consideration should be taken into optimizing treatment disparities relative to demographic status.

Evaluation of Educational YouTube Videos for Distal Radius Fracture Treatment

Purpose

Distal radius fractures (DRFs) are one of the most common fractures in adults. Adequate patient education is crucial for adherence to treatment. YouTube is a popular, accessible resource that has become a valuable tool for obtaining health information. The current study evaluated the top 50 YouTube videos on DRF treatment for patient education.

Methods

A systematic search was conducted on YouTube using three searches to obtain 150 videos. Duplicate, nonrelevant, paid, and non-English videos were removed, and the top 50 rank-ordered videos were reviewed and characterized in terms of general (views, likes, video length, and publication date), source (publisher affiliation, presenter type, and target audience), and content (media type, topic coverage, advertisements, and bias) parameters.

Results

Only 56% of videos were directed toward patients versus 40% for health care providers, highlighting a gap in patient-oriented educational content on YouTube. Most (86%) videos included effective visual aids, aligning with best practices for educational videos. Surgical management was overrepresented in 64% of the videos as opposed to nonsurgical management in 34% of videos. Only 31% of patient-oriented videos discussed surgical complications. Home exercises were emphasized in 75% of the videos discussing recovery topics.

Conclusions

Although YouTube has the potential to be an effective resource for disseminating health information to patients, it has several limitations for education in DRF treatment including the lack of patient-oriented educational videos, overrepresentation of surgical treatment, and lack of information on surgical complications. Nonetheless, YouTube may have an important role as a supplementary resource, especially in certain topics such as guiding postoperative recovery with home exercises.

Clinical relevance

This study allows health care providers and content creators to proactively address information gaps identified in educational YouTube videos on DRF treatment. It helps characterize the role of YouTube in supporting the treatment and recovery of patients experiencing DRFs.

Risk of Volar Locking Plate Removal After Distal Radius Fractures: Time-to-Event Analysis

PURPOSE

The primary purpose of this study was to describe the rate of volar locking plate (VLP) removal after distal radius fracture and how long it takes for the risk of VLP removal to stabilize. The secondary purpose was to describe the reasons for VLP removal and analyze the relationship between it and the Soong index.

METHODS

This was a single-center retrospective cohort study. Patients aged >18 years with distal radius fracture who underwent VLP fixation were included. Hardware removal, time until VLP removal, and the primary reason for removal were recorded. The implant prominence was measured as described by Soong. We used Kaplan-Meier curves and risk tables to describe the risk of VLP removal and variation over time. Multivariable logistic regression was used to assess the relationship between Soong grade and VLP removal.

RESULTS

A total of 313 wrists were included. There were 35 cases of VLP removal, with an overall incidence of 11.2% at 15 years of follow-up. The incidence rate was 1.2 per 100 individuals per year for the entire cohort. The risk of VLP removal decreased from 6.2% in the first postoperative year to 1.7% in the second year and 1.4% in the third year. Beyond that, the rate remained <1% per year throughout the follow-up period. The median hardware removal time was 11 months. The main reasons for VLP removal were tenosynovitis, implant-associated pain, and screw protrusion. We found no association between Soong grade and VLP removal.

CONCLUSIONS

Volar locking plate removal after distal radius fracture was more common in the first year after surgery and remained notable until the third year. Regular monitoring and patient education to assess possible complications related to hardware are important during this period.

Efficacy of cast immobilization versus surgical treatment for distal radius fractures in adults: a systematic review and meta-analysis

This articl e includes high-quality randomized controlled trials in recent years and updates the past meta-analysis. It has been proved that cast immobilization can achieve similar functional results, reduce economic burden in the long-term compared with surgery, and provide a basis for doctors to make treatment choices.

PURPOSE

The efficacy of conservative and surgical treatment of distal radius fractures (DRFs) in adults is still controversial. Recently, some high-quality randomized controlled trials (RCTs) evaluated the efficacy of both treatments. We hypothesized that treatment of DRFs with closed reduction and cast immobilization would achieve functional outcomes similar to surgery.

METHODS

This study is a systematic review and summary of RCTs comparing conservative and surgical management of DRFs from 2005 to March 2022. Patients were evaluated for functional and imaging outcomes and complications.

RESULTS

A total of 11 studies [1-11] included 1775 cases of DRFs. At 1-year follow-up, the cast group had lower mean differences (MDs) in DASH scores than the surgery group by - 2.55 (95% CI =  - 5.02 to - 0.09, P = 0.04); with an MD of 1.63 (95% CI = 1.08-2.45, P = 0.02), while the surgery group had a lesser complication rate than the cast group.

CONCLUSIONS

At 1-year follow-up, the lower DASH scores of the cast group showed advantages of this treatment, but the complication rate was higher than that of the surgery group. There was no massive distinction in other scoring methods.

Epidemiology and Treatment of Distal Radius Fractures in Finland-A Nationwide Register Study

A distal radius fracture (DRF) is one of the most common fractures in emergency units, the treatment of which requires considerable health care resources. We analyzed the incidence rate for DRFs and the incidence rate of operative treatment over a five-year period, 2015–2019, for the entire population of Finland and all ages. Data was obtained from the Finnish National Care Register for Health Care. The results were counted as cases per 100,000 person/years and standardized with the European Standard Population 2013. The mean annual incidence rate of DRF was 204.90 (203.21–206.59) in specialist care and 69.53 (68.55–70.52) in primary care. It peaked among the pediatric population and among elderly women, in whom it was more than four times as common compared to men of the same age. No increase in the incidence rate of DRFs was found. The mean incidence rate of operative treatment was 45.66 (45.66–45.66)/100,000 person/years, 2015–2019; women were more likely to undergo operative treatment. Altogether, 15–18% of DRFs were operated on over the study period. The annual incidence rate of operations seemed to plateau compared to earlier studies in Finland.

Magnitude, Direction, Temporal Patterns, and Frequency of Loss of Distal Radius Fracture Reduction in Women 50 Years and Older

PURPOSE

To determine the magnitude, direction, temporal patterns, and frequency of reduction loss following nonsurgical, closed treatment of distal radius fractures in women 50 years and older and correlate these observations with bone mineral density and age.

METHODS

We reviewed registry data on 1,148 patients 50 years and older with distal radius fractures managed by closed reduction and cast immobilization. Radial inclination (RI), ulnar variance (UV), and radial tilt (RT) were measured immediately and at 1, 2, 3, 6, 9, and 12 weeks after reduction. Magnitude, direction, frequency, and patterns of change were compared at each time point and correlated with bone mineral density T-scores and age using paired t tests in a mixed effects model.

RESULTS

Over 12 weeks, RI decreased by 3° ± 5°, the majority occurring in the first 2 weeks and significantly correlated with bone mineral density T-score and age. Unexpectedly, RI increased over time in 5% of patients. Ulnar variance increased by 2.3 ± 1.7 mm, the majority occurring in the first 3 weeks and correlated with age. Radial tilt changed by 7° ± 11° in those displacing dorsally and 8° ± 12° in those displacing volarly at 12 weeks, with the majority occurring in the first 3 weeks and significantly correlating with age. Ulnar variance and RT continued to change by small increments between weeks 3 and 6. Nearly 90% of our cohort experienced measurable loss of reduction and 50% changed at least 5° RI, 11° RT, and 2 mm UV.

CONCLUSIONS

Most distal radius fracture managed with closed reduction and casting have some loss of reduction, the majority occurring in the first 3 weeks and correlated with increased age and osteoporosis. This guides clinicians in informing patients about expected reduction loss, frequency of clinical and radiographic follow-up, and timing of discussions regarding the need for surgery.

Comparison of treatment results between surgical and conservative treatment of distal radius fractures in adults: A meta-analysis of randomized controlled trials

OBJECTIVE

This meta-analysis study aims to determine the efficacy and safety of surgical and conservative treatments for distal radius fractures (DRFs) in adults.

METHODS

Reports of randomized controlled trials were retrieved from the Web of Science, Pubmed, Google Scholar, EMBASE, Cochrane Library, Medline, Ovid, and BIOSIS for studies that met the eligibility criteria. The search was limited to human subjects and had no language limits. The search strategy was check by two independent reviewers. If there was any dispute, a third reviewer was consulted. Primary outcomes were: (1) the active wrist range of motion including flexion, extension, pronation, supination, radial, and ulnar deviation; (2) the Disabilities of the Arm, Shoulder, and Hand (DASH) score; and (3) radiological outcomes including radial inclination and ulnar variance. Secondary outcomes were the number of complications including non-infectious and infectious. Quality assessment was performed using the Cochrane Risk of Bias Tool provided by the Cochrane Review Manager 5.3.

RESULTS

A total of 10 randomized controlled trials were included. The meta-analysis detected no statistically significant difference in pooled data for complications not included infection (MD 0.64, CI: 0.33 to 1.23, Z=1.34, p=0.18). Surgical treatment achieved a better range of motion (MD 3.76, CI: 1.58 to 5.95, Z=3.37, p=0.0007), DASH score (MD -6.57, CI: -9.08 to -4.06, Z=5.12, p<0.00001), and radiographic outcomes (MD 3.75, CI: 2.75 to 4.74, Z=7.37, p<0.00001) compared with conservative treatment. In contrast, the conservative treatment achieved less infection rate compared with surgical treatment (MD 4.09, CI: 1.18 to 14.21, Z=2.21, p=0.03).

CONCLUSION

Findings of this study reveal that when compared with conservative treatment, surgical treatment can ensure better clinical and radiological results for the treatment of DRFs in adults. Although similar complication rates can be encountered with both treatment modalities, it should be taken into account that the rate of infection may be higher in surgical treatment.

Improvements in radiographic and clinical assessment of distal radius fracture healing by FE-estimated bone stiffness

Bone strength determined from finite element (FE) modelling provides an estimate of fracture healing progression following a distal radius fracture (DRF), but how these measures relate to patient-reported outcomes and functional outcomes remains unknown. We hypothesized that changes in bone stiffness and bone mineral density measured using high-resolution peripheral quantitative computed tomography (HR-pQCT) are associated with clinically available measures of functional and patient-reported outcomes. We also aimed to identify which clinical outcome measures best predict fracture stiffness and could therefore be used to inform cast removal.

Participants (n = 30) with stable distal radius fractures were followed for two week intervals from the time of fracture until two months post-fracture, then at three months and six months post-fracture. At each follow-up, participants underwent clinical, radiographic, and functional assessments, as well as had their fractured wrist scanned using HR-pQCT. Recovery of bone stiffness during fracture healing was determined from micro-FE (μFE) models generated from HR-pQCT image data.

During the DRF healing process, significant longitudinal changes were found in μFE-estimated stiffness, patient-reported outcomes, grip strength, range of motion (ROM), tenderness, number of cortices healed based on radiographs, and fracture line visibility (p < 0.05); however, no significant change was detected in HR-pQCT based total bone mineral density. Patient-reported outcomes, such as the Patient-Rated Wrist Evaluation (PRWE) and the Quick Disability of the Arm, Shoulder and Hand (QuickDASH) questionnaire, correlated strongly with μFE-estimated stiffness (0.61 ≥ r_m ≥ 0.66). Based on μFE-estimated stiffness, PRWE and QuickDASH are the best predictors of stiffness recovery (p < 0.05) and may be used to guide duration of cast immobilization in the clinical setting.

•

Recovery of fracture stiffness may inform time required for cast immobilization.

•

Patient reported outcomes predict rate of fracture stiffness recovery.

•

Radiographic outcomes correlate weakly with fracture stiffness.

•

Patient reported outcomes may inform duration of cast immobilization.

Surgical fixation of fractures of the distal radius within 2 weeks reduces postoperative finger stiffness

Locked anterior plating remains the most common form of surgical fixation for displaced fractures of the distal radius. We hypothesized that delayed surgical fixation later than 2 weeks after injury contributes to poorer patient outcomes for patients with displaced or intra-articular fractures of the distal radius. We conducted a retrospective cohort study of 158 patients who underwent locked anterior plating for an intra-articular or displaced fracture of the distal radius using multiple regression analysis to identify any relationship between patient, injury or treatment factors with the patient-rated wrist and hand evaluation score or finger and wrist stiffness. There was no significant correlation between timing of surgery and functional scores. A delay in time to surgery of more than 2 weeks did correlate significantly with increased finger and thumb stiffness. However, this relationship was not seen for wrist stiffness. Our study supports the consensus that early recovery and function is facilitated by surgical fixation within 2 weeks and that delayed fixation beyond this may contribute to protracted finger stiffness.Level of evidence: IV.

The efficacy of 3D printing-assisted surgery in treating distal radius fractures: systematic review and meta-analysis

Aim: To compare the efficacy of 3D printing-assisted surgery with routine surgery in the treatment of distal radius fractures to evaluate whether 3D printing technology has more advantages. Materials & methods: To retrieve all published studies that compared the efficacy of 3D printing-assisted surgery with routine surgery for distal radius fractures. Operation time, frequency of intraoperative fluoroscopy, blood loss and other outcomes were assessed. Results: The results suggested that 3D printing-assisted surgery was better than routine surgery in the fields of operation time, frequency of intraoperative fluoroscopy, and blood loss. Conclusion: In the treatment of distal radius fractures, 3D printing-assisted surgery may be superior to routine surgery.

Operative vs Nonoperative Treatment of Distal Radius Fractures in Adults: A Systematic Review and Meta-analysis

IMPORTANCE

No consensus has been reached to date regarding the optimal treatment for distal radius fractures. The international rate of operative treatment has been increasing, despite higher costs and limited functional outcome evidence to support this shift.

OBJECTIVES

To compare functional, clinical, and radiologic outcomes after operative vs nonoperative treatment of distal radius fractures in adults.

DATA SOURCES

The PubMed/MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases were searched from inception to June 15, 2019, for studies comparing operative vs nonoperative treatment of distal radius fractures.

STUDY SELECTION

Randomized clinical trials (RCTs) and observational studies reporting on the following: acute distal radius fracture with operative treatment (internal or external fixation) vs nonoperative treatment (cast immobilization, splinting, or bracing); patients 18 years or older; and functional outcome. Studies in a language other than English or reporting treatment for refracture were excluded.

DATA EXTRACTION AND SYNTHESIS

Data extraction was performed independently by 2 reviewers. Effect estimates were pooled using random-effects models and presented as risk ratios (RRs) or mean differences (MDs) with 95% CIs. Data were analyzed in September 2019.

MAIN OUTCOMES AND MEASURES

The primary outcome measures included medium-term functional outcome measured with the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) and the overall complication rate after operative and nonoperative treatment.

RESULTS

A total of 23 unique studies were included, consisting of 8 RCTs and 15 observational studies, that described 2254 unique patients. Among the studies that presented sex data, 1769 patients were women [80.6%]. Overall weighted mean age was 67 [range, 22-90] years). The RCTs included 656 patients (29.1%); observational studies, 1598 patients (70.9%). The overall pooled effect estimates the showed a significant improvement in medium-term (≤1 year) DASH score after operative treatment compared with nonoperative treatment (MD, -5.22 [95% CI, -8.87 to -1.57]; P = .005; I2 = 84%). No difference in complication rate was observed (RR, 1.03 [95% CI, 0.69-1.55]; P = .87; I2 = 62%). A significant improvement in grip strength was noted after operative treatment, measured in kilograms (MD, 2.73 [95% CI, 0.15-5.32]; P = .04; I2 = 79%) and as a percentage of the unaffected side (MD, 8.21 [95% CI, 2.26-14.15]; P = .007; I2 = 76%). No improvement in medium-term DASH score was found in the subgroup of studies that only included patients 60 years or older (MD, -0.98 [95% CI, -3.52 to 1.57]; P = .45; I2 = 34%]), compared with a larger improvement in medium-term DASH score after operative treatment in the other studies that included patients 18 years or older (MD, -7.50 [95% CI, -12.40 to -2.60]; P = .003; I2 = 77%); the difference between these subgroups was statically significant (test for subgroup differences, P = .02).

CONCLUSIONS AND RELEVANCE

This meta-analysis suggests that operative treatment of distal radius fractures improves the medium-term DASH score and grip strength compared with nonoperative treatment in adults, with no difference in overall complication rate. The findings suggest that operative treatment might be more effective and have a greater effect on the health and well-being of younger, nonelderly patients.
