Undiagnosed vertebral fragility fractures in patients with distal radius fragility fractures: an opportunity for prevention of morbimortality in osteoporotic patients in developing countries.

Our study investigates vertebral fractures in individuals with distal radius fractures. Among 512 patients, 41.21% had vertebral fractures, predominantly in the lumbar spine. These findings highlight the importance of screening for vertebral fractures in this population, informing early intervention strategies to mitigate risks associated with osteoporosis. PURPOSE: This study's main goal was to look into the frequency, location, kind, and severity of asymptomatic vertebral fragility fractures (VFF) in people who had fractures of the fragility of the distal radius. Although VFF is frequently misdiagnosed, it is linked to higher mortality, morbidity, and hip fracture risk. The study also attempted to investigate the relationship between VFF and certain demographic and lifestyle factors, as well as FRAX data, in this patient population. METHODS: Between January, 2021, and January, 2022, individuals with low-energy distal radial fractures who presented to the emergency room of tertiary care hospital of Karachi, Pakistan, were the subject of a cross-sectional study and were 45 years of age or older except those who fitted the exclusion criteria (n = 208). The thoracic and/or lumbar spine was imaged using radiology, and information on demographics, way of life, and FRAX (Fracture Risk Assessment Tool) was gathered. Using the Genant semiquantitative approach, an impartial and blinded orthopaedist identified VF in the images and determined their severity. SPSS version 20 was used to analyse the data. RESULTS: Two hundred eleven (41.21%) of them were found to have radiographic VFF and only 12 (2.34%) of the 512 patients who were tested were getting osteoporotic therapy. The thoracic spine (32.7%), followed by the lumbar spine (43.12%), was the area most frequently afflicted. In 24.17% of the patients, multiple fractures of the thoracolumbar spine were found. The wedge form (54.5%), followed by biconcave (30.81%) and crush (14.7%), was the most prevalent VFF type. The majority of detected VFF were rated as having a 25-40% height loss (64.9%) then severe (> 40%) fractures (35.1%), according to the Genant grading method. Notably, there were no variations in smoking, drinking, BMI, or FRAX score between patients with and without VFF that were statistically significant. CONCLUSION: Based on our study's findings, it is clear that osteoporotic vertebral fragility fractures occur in almost half of individuals with distal radius fractures. The lumbar spine is notably the most affected region, predominantly with wedge fractures. Given the high prevalence of asymptomatic vertebral fragility fractures (VFF), proactive measures are necessary to mitigate associated risks. Prioritising comprehensive fall risk assessments for these patients and interventions to enhance bone mineral density and strength are crucial. Early identification of asymptomatic VFF enables timely intervention, optimising patient care and minimising the risk of complications in this vulnerable population.

Seasonal variation of surgically treated distal radius fracture in Japan using inpatient database: cross-sectional study.

INTRODUCTION: The purpose of this study was to clarify the relationship between seasonal variation and distal radius fractures using diagnosis procedure combination data in Japan. MATERIALS AND METHODS: The participants were hospitalized patients who underwent surgical treatment for distal radius fracture as the primary injury at hospitals that introduced the diagnosis procedure combination system between April 2011 and March 2016. We obtained a summary table of the month of admission, region of residence, age at admission, and sex of the patients from the Ministry of Health, Labour and Welfare and evaluated it by month, region, age group, and sex. RESULTS: The total number of patients for the 5 years from 2011 to 2016 was 105,025. There were 29,224 male and 75,801 female participants, with a female-to-male ratio of 2.6. The mean age was 60.2 (standard deviation, 20.8) years. Distal radius fractures occurred more frequently in the winter, especially among female individuals in eastern Japan. Female participants aged ≥ 50 years tended to have a higher incidence of distal radius fracture in winter. The incidence of distal radius fracture among male participants aged 0-19 years was higher from spring to autumn. CONCLUSION: Surgically treated distal radius fractures occur frequently during the winter months among female individuals in eastern Japan or those aged ≥ 50 years and increase from school age to adolescence, especially in male individuals from spring to autumn. We should be aware of the high incidence of distal radius fractures in winter, especially in regions with snowfall and cold temperatures.

Incidence of four major osteoporotic fragility fractures among older individuals in Sado, Japan, in 2020.

INTRODUCTION: This study compared the 2020 incidence of fragility fractures in Sado City with those from 2004 to 2015. MATERIALS AND METHODS: Data from patients aged ≥ 60 years living in Sado City with fragility fractures in the hip, vertebral, distal radius, and proximal humerus between January 1 and December 31, 2020, were collected. We examined the number and incidence of four types of osteoporotic fractures in the older population aged ≥ 60 years living in Sado City in 2020. We compared the results with those of the 2004, 2010, and 2015 surveys, examining the temporal change and trend in the incidence of the four fracture types in this population. We investigated the use rate of anti-osteoporotic medications and the relationship between their administration and the occurrence of fragility fractures. RESULTS: The age-specific incidence of hip fractures slightly decreased from 2015. However, the incidence of the other three fractures slightly increased, although the difference was not statistically significant. The incidence of hip fractures markedly increased in the 80 s. In 2020, the percentage of patients taking anti-osteoporotic agents before the occurrence of fractures decreased to 12.4% from 14.5% in 2015; it increased from 4% in 2004 to 7.6% in 2010. CONCLUSION: The 2020 incidence of the four fractures did not decrease, and the percentage of patients receiving anti-osteoporotic agents did not increase. A higher frequency of osteoporosis treatment is necessary to reduce the incidence of fragility fractures. We recommend using anti-osteoporotic agents to prevent hip fractures among individuals in their mid-70 s and above.

Peripheral nerve blocks for closed reduction of distal radius fractures-A systematic review with meta-analysis and trial sequential analysis.

BACKGROUND: Peripheral nerve blocks may provide better conditions for closed reduction of distal radius fractures as compared to other more frequently used modalities. In this systematic review, we evaluate existing evidence on the effect and harm of peripheral nerve blocks for closed reduction of distal radius fractures in adults. METHODS: We performed a systematic review with meta-analysis and trial sequential analysis including trials investigating the use of peripheral nerve blocks for closed reduction of distal radius fractures. Co-primary outcomes were (1) the quality of the closed reduction measured as the proportion of participants needing surgery afterwards and (2) pain during closed reduction. RESULTS: Six trials (n = 312) met the inclusion criteria. One trial reported on the need for surgery with 4 of 25 participants receiving nerve block compared to 7 of 25 receiving haematoma block needing surgery (RR 0.57, 96.7% CI [0.19; 1.71], p = .50). Four trials reported pain during closed reduction. In a meta-analysis, pain was not statistically significantly reduced with a nerve block (-2.1 Numeric Rating Scale (NRS) points (0-10), 96.7% CI [-4.4; 0.2], p = .07, tau2 = 5.4, I2 = 97%, TSA-adj. 95% CI [-11.5; 7.3]). No trial sequential boundaries were crossed, and the required information size was not met. Pre-planned subgroup analysis on trials evaluating ultrasound guided peripheral nerve blocks (patients = 110) showed a significant decrease in 'pain during reduction' (-4.1 NRS, 96.7% CI [-5.5; -2.6], p < .01, tau2 = 0.9, I2 = 80%). All trial results were at high risk of bias and the certainty of the evidence was very low. CONCLUSION: The certainty of evidence on the effect of peripheral nerve blocks for closed reduction of distal radius fractures is currently very low. Peripheral nerve blocks performed with ultrasound guidance may potentially reduce pain during closed reduction. High-quality clinical trials are warranted.

Early Daily Activity: Development and description of an occupation-based intervention for surgically repaired distal radius Fractures.

OBJECTIVE: To describe the theoretical development and structure of an occupation-based intervention for people with a surgically repaired distal radius fracture. INTERVENTION DEVELOPMENT AND RATIONALE: The Early Daily Activity (EDA) intervention uses the performance of strategically selected daily activities as the primary rehabilitative strategy. Occupation-based interventions are recommended for hand injury rehabilitation but are often poorly described and lack explicit theoretical underpinnings. The EDA-intervention was developed from exploratory research that informed the theory and structure. The theoretical principles are that daily activity performance is (i) safe within defined parameters (ii) appropriately self-determined (iii) produces high ranges and amounts of therapeutic movement, and (iv) builds psychosocial competencies. INTERVENTION DESCRIPTION: The EDA-intervention is designed to be commenced within 2 weeks of surgery. There are three key components. The first is activity-specific education to emphasise the safety, benefits, and therapeutic actions of activity performance. A set of parameters for defining safe activities is described to support education. The second component is patient-therapist collaboration to select a range of daily activities that provide a 'just-right' challenge. Collaboration occurs at regular intervals throughout the rehabilitation period to incrementally increase the challenge of activities. The third component is performance of activities at-home targeted at improving range of movement and function. NEXT STEPS: The EDA-intervention can be used by hand therapists, but it has not yet undergone effectiveness evaluation. A planned study will explore clinician readiness to adopt the EDA-intervention, inform iterative changes to the protocol and the design of feasibility and effectiveness studies.

Radiographic measurements in distal radius fracture evaluation: a review of current techniques and a recommendation for standardization.

Radiographic measurements play a crucial role in evaluating the alignment of distal radius fractures (DRFs). Various manual methods have been used to perform the measurements, but they are susceptible to inaccuracies. Recently, computer-aided methods have become available. This review explores the methods commonly used to assess DRFs. The review introduces the different measurement techniques, discusses the sources of measurement errors and measurement reliability, and provides a recommendation for their use. Radiographic measurements used in the evaluation of DRFs are not reliable. Standardizing the measurement techniques is crucial to address this and automated image analysis could help improve accuracy and reliability.

The accuracy of the ultrasound measured transverse cricoid diameter and the epiphyseal transverse diameter of the distal radius in predicting the pediatric endotracheal tube size.

BACKGROUND: In everyday pediatric anesthesia practice, clinicians frequently exchange an already inserted endotracheal tube because of a leak or resistance causing significant morbidity. We investigated the accuracy of two ultrasound measurements; the transverse cricoid diameter and epiphyseal diameter of the distal radius in the prediction of endotracheal tube size that best fits in children compared to age-based formulas. PATIENTS: One hundred children (1-6 years) who underwent elective surgery with endotracheal tube whether cuffed (n = 50) or uncuffed (n = 50) were enrolled. The primary endpoint was the agreement between the reference tube size for which its outer diameter was selected based on transverse cricoid diameter and the final best-fit-ETT. The Correlation and Bland Altman agreement tests were conducted between best-fit-ETT outer diameter and ultrasound-measured outer diameter, and between best-fit-ETT inner diameter and inner diameter calculated by age-based formulas. RESULTS: The agreement rate between transverse cricoid diameter-based endotracheal tube size and best-fit-ETT size was 88% in cuffed group compared to 90% in uncuffed group. A significant positive correlation was reported between the outer diameter of best-fit-ETT and the outer diameter measured by the two ultrasound methods. A lower degree of positive correlation was reported between the inner diameter of best-fit-ETT, and the inner diameter calculated by age-based formulas. Bland Altman's analysis showed agreement between best-fit-ETT outer diameter and epiphyseal diameter of the distal radius in both groups and with transverse cricoid diameter in the cuffed group, with no agreement with age-based formulas in either group. CONCLUSIONS: Both transverse cricoid diameter and epiphyseal diameter of the distal radius are reliable predictors of the size of best-fit-ETT pediatric endotracheal tube compared to age-based formulas. To save time and effort, we recommend the US measurement of the epiphyseal diameter of distal radius in the preoperative visit and documenting the predicted tube size with the preoperative assessments.

Association between carpal height ratio and ulnar variance in normal wrist radiography.

INTRODUCTION: The wrist joint is a complex anatomical structure, and various radiographic parameters are utilized to assess its normal alignment and orientation. Among these parameters are carpal height ratio (CHR) and ulnar variance (UV). Previous literature has indicated that factors such as age and gender may influence these parameters; However, there is a lack of studies investigating these differences specifically in the Middle East or Jordan. Additionally, no prior research has explored the relationship between UV and CHR. Therefore, the objective of this study is to investigate these critical radiological parameters and their associations. METHODOLOGY: A cross-sectional study design was employed, wherein a total of 385 normal wrist X-rays were reviewed, and CHR and UV were measured. Intra-observer and inter-observer reliability assessments were conducted to ensure the consistency and accuracy of measurements. Additionally, the association between UV and CHR was measured and plotted for further analysis. RESULTS: In our study, the mean CHR was 0.5 (range: 0.4 to 1.5), and the mean UV was - 0.3 mm (range: -5.8 mm to 4.1 mm). We found a significant negative correlation between CHR and age (p < 0.05). No significant gender differences were observed in UV and CHR. Additionally, a weak positive correlation was found between UV and CHR (Pearson correlation coefficient = 0.13, p = 0.01; adjusted R2 = 0.014, p = 0.02). CONCLUSION: Age correlated significantly with a decline in carpal height ratio. Additionally, ulnar variance had a week positive yet significant correlation with carpal height ratio. LEVEL OF EVIDENCE: Cross-sectional study, Level III.

Volar fixed plating of distal radius fractures: optimizing plate position for enhanced clinical outcomes.

BACKGROUND: The precise influence of plate position on clinical outcomes in the context of volar fixed-angle plating for distal radius fractures is not fully understood. This article aims to investigate the influence of plate position on clinical results, and functional outcomes in patients treated with volar fixed plating for distal radius fractures. METHODS: A total of 58 patients with 64 distal radius fractures were included in the study. Patient demographics, fracture characteristics, surgical details, and radiographic data were collected. Post-operative AP and Lat views of all patients taken on the first day after surgery were evaluated. Volar Tilt, Radial Inclination and Radial Height measurements were used as reduction criteria. In the follow-up, the patients were called for their last control, flexion and extension angles of the wrist and Mayo Wrist Scores, the distance of the plate to the joint line and the angle between the plate and the radial shaft were measured and recorded. RESULTS: A total of 64 distal radius fractures, with a mean age of 46.9 years, and the mean follow-up period 24.9 months were included in this study. There was a significant relationship between the Radial Inclination and Plate-Shaft Angle variables and the Mayo Wrist Score at a 99% confidence interval. Additionally, a relationship was observed between the Radial Height variable and the Mayo Score at a 90% confidence interval. A significant positive association was observed between radial inclination and achieving a Good-to-Excellent Mayo score (OR = 1.28, 95% CI [1.08-1.51], p = 0.004). Plate distance to joint line demonstrated a marginally significant positive association with a Good-to-Excellent Mayo score (OR = 1.31, 95% CI [0.97-1.77], p = 0.077). Univariate analysis revealed a significant negative association between plate-shaft angle and achieving a Good-to-Excellent Mayo score (OR = 0.71, 95% CI [0.52-0.99], p = 0.045). This negative association remained statistically significant in the multivariate analysis (p = 0.016). CONCLUSION: Radial inclination, plate distance to joint line, and angle between plate and radius shaft were identified as significant factors associated with improved Mayo Wrist Scores.

Radiographic and clinical outcomes of muenster and sugar tong splints for distal radius fractures: a comparative study.

BACKGROUND: Non-operative management is typically indicated for extra-articular distal radius fractures. Conservative treatments such as Sugar tong splints (STs) and Muenster splints (MUs) are commonly used. However, there is limited research and outcome data comparing the two splint types. Therefore, this study aimed to investigate and compare the radiographic and clinical outcomes of treatment using STs and MUs. METHODS: In this retrospective comparative study, we aimed to evaluate and compare the radiographic and clinical outcomes of STs and MUs for the treatment of distal radius fractures. The study included 64 patients who underwent closed reduction (CR) in the emergency room and were treated with either STs or MUs splints (STs group: n = 38, MUs group: n = 26). Initial X-rays, post-CR X-rays, and last outpatient follow-up X-rays were evaluated. Radial height (RH), ulnar variance (UV), radial inclination (RI), and volar tilt (VT) were measured by a blinded investigator. The Quick DASH form was applied to measure patients' satisfaction after treatments. RESULTS: There were no significant differences in baseline characteristics, initial radiographic measurements, or radiographic measurements immediately after CR between the two groups. However, the overall radiological values deteriorated to some degree in both groups compared to the post-CR images. Furthermore, using a paired test, the STs group showed significant differences in RH and RI, and the MUs group showed significant differences in RH and UV between the last follow-up and post-CR images. CONCLUSIONS: The study concluded that there was no difference in clinical outcomes between the two splint types. However, both STs and MUs groups showed reduced radiographic parameters, and the MUs group showed a significant reduction of RH and UV in the treatment of distal radius fractures. LEVEL OF EVIDENCE: Level IV; Retrospective Comparison; Treatment Study.

Stable elastic nail application with poller K-wire for Irreducible distal radius metaphyseal-diaphyseal Junction fractures in preadolescents: a new operative technique.

BACKGROUND: Surgical treatment of irreducible distal radius diaphyseal- metaphyseal junction fractures involves difficulties as the fracture remains too proximal for K-wire fixation and too distal for the elastic stable intramedullary nail. Our study aims to present the clinical results of applying an elastic stable intramedullary nail with a poller K-wire to achieve both reduction and stable fixation. PATIENTS AND METHODS: A retrospective analysis was performed on 26 patients who underwent ESIN with a poller K-wire for distal radius diaphyseal-metaphyseal region fracture. Reduction parameters such as residual angulation and alignment were evaluated on postoperative follow-up radiographs. Changes in angular and alignment parameters on follow-up radiographs were recorded. Wrist and forearm functions were evaluated at the last follow-up. RESULT: There were 17 male and nine female patients with an average age of 10.9. The residual angulation in coronal and sagittal planes on immediate postoperative radiographs was 4.0 ± 1.62° and 3.0 ± 1.26°, respectively. The mean translation rate on immediate postoperative radiographs was 6.0 ± 1.98% and 5.0 ± 2.02% in the coronal and sagittal planes, respectively. No change was observed in translation rates in the last follow-ups. The mean angulation in the coronal and sagittal planes measured on 6th-week radiographs was 4.0 ± 1.72°and 3.0 ± 1.16°, respectively. No significant difference was observed in angular changes in the sagittal and coronal planes at the last follow-up (p > 0.05). No tendon injury or neurovascular injury was observed in any of the patients. CONCLUSION: In the surgical treatment of pediatric DRDMJ fractures, applying ESIN with poller K-wire is an effective, safe, and novel method for achieving reduction and stable fixation.

Clinical application of instant 3D printed cast versus polymer orthosis in the treatment of colles fracture: a randomized controlled trial.

BACKGROUND: The shortcomings of plaster in water resistance, air permeability, skin comfort, fixed stability and weight of wearing are still to be solved. 3D printed cast can overcome the above shortcomings. At present, there is a relative lack of data on the clinical application of 3D printed cast, probably due to its complexity, relatively long operating time, and high price. We aimed to compare and evaluate the short-term effectiveness, safety and advantages of 3D printed wrist cast versus polymer orthosis in the treatment of Colles fracture. METHODS: Forty patients with Colles fracture in our hospital from June to December 2022 were selected and divided into an observation group (20 patients, treated with instant 3D printed cast) and a control group (20 cases, treated with polymer orthosis). Both groups treated with manual reduction and external fixation. The visual analogue scale (VAS), immobilization effectiveness and satisfaction scores, Disability of the Arm, Shoulder and Hand (DASH) score, complications and imaging data were collected and compared before immobilization and at 2, 6 and 12 weeks after the fracture. RESULTS: VAS at 2 weeks after the fracture was significantly lower in the observation group than in the control group ( P < 0.05). The immobilization effectiveness and satisfaction scores at 6 weeks after the fracture were significantly higher in the observation group than in the control group (all P < 0.05). The DASH scores at 2 and 6 weeks after the fracture were significantly lower in the observation group than in the control group (all P < 0.05). There wasn't rupture of the printed cast or orthosis in both groups. There were 2 cases of skin irritation in the control group, and no skin irritation occurred in the observation group. The palmar tilt angle and ulnar inclination angle at 2 weeks and 12 weeks after the fracture were significantly higher in the observation group than in the control group (all P < 0.05). CONCLUSIONS: Both instant 3D printed cast and polymer orthosis are effective in the treatment of Colles fracture. But instant 3D printed cast is better than polymer orthosis in areas of good clinical and imaging performance, and high patient satisfaction and comfort.

Relation between the dash score and radiographic evaluation of the wrist in patients with wrist fracture.

Traditionally, the assessment of distal radius fracture outcomes has been based on radiological measurements and self-evaluation scores. However, there is uncertainty regarding how accurately these measurements reflect the patient's perception of their outcome. In this study, we examined the correlation between radiological measurements and patient-perceived outcomes using the Disabilities of the Arm, Shoulder, and Hand outcome (DASH) score. 140 individuals who had recovered from a distal radius fracture. and had been treated with DVR, Kapandji, percutaneous pinning or closed reduction were included in the study. The retrospective assessment included 78 females and 62 males, with a mean DASH score of 3.54 points.Except for the ulnar variance, the study found little to no significant association between the DASH score and the final radiological measurement.In summary, the DASH score did not always indicate that a superior radiological result translated into a better patient-perceived outcome.

Impact of early rehabilitation therapy on functional outcomes in patients post distal radius fracture surgery: a systematic review and meta-analysis.

BACKGROUND: This meta-analysis aims to investigate the efficacy of early rehabilitation on patients who have undergone surgery for distal radius fractures (DRFs) with palmar plating, focusing on multiple outcome measures including upper limb function, wrist function, back extension mobility, pain levels, and complications. METHODS: A rigorous search strategy adhering to the PRISMA guidelines was employed across four major databases, including PubMed, Embase, Web of Science, and the Cochrane Library. Studies were included based on stringent criteria, and data extraction was performed independently by two reviewers. Meta-analysis was conducted employing both fixed-effect and random-effects models as dictated by heterogeneity, assessed by the I2 statistic and chi-square tests. A total of 7 studies, encompassing diverse demographic groups and timelines, were included for the final analysis. RESULTS: The meta-analysis disclosed that early rehabilitation yielded a statistically significant improvement in upper limb function (SMD -0.27; 95% CI -0.48 to -0.07; P < 0.0001) and back extension mobility (SMD 0.26; 95% CI 0.04 to 0.48; P = 0.021). A notable reduction in pain levels was observed in the early rehabilitation group (SMD -0.28; 95% CI -0.53 to -0.02; P = 0.03). However, there were no significant differences in wrist function (SMD -0.13; 95% CI -0.38 to 0.12; P = 0.36) and complications (OR 0.99; 95% CI 0.61 to 1.61; P = 0.96). CONCLUSIONS: Early rehabilitation post-DRF surgery with palmar plating has been found to be beneficial in enhancing upper limb functionality and back extension mobility, and in reducing pain levels. Nevertheless, no significant impact was observed regarding wrist function and complications.

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.

Development of a Patient Decision Aid for Distal Radius Fractures in Patients aged ≥65 years.

PURPOSE: The ideal management of distal radius fractures (DRFs) in patients aged 65 years and older is debated. Acknowledging the evidence that both nonsurgical and surgical treatment yield similar outcomes one year after injury, a patient decision aid (PDA) could facilitate patient engagement in treatment decision-making. The purpose of this study was to develop a PDA to guide patients in the treatment of DRFs in patients ≥65 years of age. METHODS: The DRF PDA was developed using an established decision sciences framework. The PDA included an overview of DRFs, treatment options (casting vs surgery), risk/benefits, and a values clarification section. During the development phase, hand surgeons and patients reviewed the PDA; then, semistructured interviews were performed with participants to elicit feedback. RESULTS: Eleven patients and 11 hand surgeons participated in the study. All patients found the PDA useful and almost all stated it would make the treatment decision easier. Most patients believed that there was enough information in the PDA, but one desired more information about surgical risks. Almost all surgeons stated the PDA would be easy for patients to use and understand, and approximately half believed that it would help patients make a more informed decision. Most surgeons expressed that the PDA would complement their usual approach to counseling patients, but some noted it would involve changes to their workflow. Most participants believed the information presented was unbiased, but one patient thought it was biased toward surgery, whereas a few surgeons believed that it was biased toward nonsurgical treatment. CONCLUSIONS: All patients expressed that the PDA was informative, comprehensive, and easy to understand and would be helpful if they were deciding about DRF treatment. Surgeons believed that patients would find the PDA easy to use and understand, but some had concerns about incorporating it into their clinic workflow. CLINICAL RELEVANCE: A decision aid for the treatment of DRFs in patients aged ≥65 years can be used to engage patients in the shared decision-making process.

Impact of Possible Sarcopenia and Nutritional Status on Postoperative Quick Disabilities of the Arm, Shoulder, and Hand Score in Geriatric Women With Distal Radius Fracture.

PURPOSE: Distal radius fracture (DRF), sarcopenia, and malnutrition have been reported to be interrelated. However, there are few reports on the effects of sarcopenia and malnutrition on DRF patients' postoperative outcomes. This study examined the healthy-side grip strength and preoperative blood tests to determine the presence of possible sarcopenia (PS) and malnutrition in geriatric women with DRF and their impact on postoperative functional outcomes. METHODS: Fifty-five woman older than 60 years treated with volar-locking plate fixation for low-energy DRF from standing-level falls were retrospectively studied. Based on the criteria of The Asian Working Group for Sarcopenia 2019, patients with a healthy-side grip strength <18 kg were defined as PS. Nutritional assessment was performed using Onodera's Prognostic Nutritional Index (PNI) before surgery, with a value <50 defined as malnutrition. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) was used for functional assessment at 1 year after surgery. Patients were divided into two groups according to PS, and patient demographic data and postoperative outcomes were compared. Multiple regression analysis was performed to estimate the regression coefficient and 95% confidence intervals for 1-year QuickDASH after surgery with adjustment for age, PS, and malnutrition. RESULTS: Possible sarcopenia was present in 10 patients (18.2%), and malnutrition in 24 patients (43.6%). Possible sarcopenia patients were older, had lower PNI, serum albumin, and both sides grip strength, and worse QuickDASH compared with non-PS patients. In multiple regression analysis, age, PS, and malnutrition were significant predictors of QuickDASH (standardized coefficient ß, 0.35, 0.34, and 0.24; 95% confidence interval, 0.22-1.02, 3.52-16.49, and 0.50-10.78). CONCLUSIONS: Possible sarcopenia with a healthy-side grip strength <18 kg and malnutrition with a PNI <50 were associated with worse 1-year QuickDASH after surgery in women DRF patients over 60 years. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic Ⅳ.

Factors Associated With Reoperation After Distal Radius Nonunion Repair.

PURPOSE: This study aimed to evaluate the incidence of, and factors associated with, reoperation after distal radius nonunion repair. METHODS: We conducted a retrospective cohort study at a multicenter academic institution and identified adult patients who underwent open reduction and internal fixation for distal radius nonunion between January 2005 and August 2021. Thirty-three patients were included in this study. The cohort consisted of 13 males (13/33) and had a median age of 56 years (interquartile ranges: 49-64). Median follow-up was 59 months (interquartile ranges: 23-126). RESULTS: Unplanned reoperations occurred in eight of 33 patients. The most common reasons for reoperation were irrigation and debridement for infection, revision surgery for persistent nonunion, and unplanned hardware removal. In total, 10 complications occurred in nine patients. The most common complications were infection and persistent nonunion; both occurred in three cases. CONCLUSIONS: Complications after distal radius nonunion repair are common. Reoperation after distal radius nonunion repair is required in approximately one of four cases. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

The Contribution of the Distal Oblique Band to Distal Radioulnar Joint Stability.

PURPOSE: The distal radioulnar joint (DRUJ) is supported by an array of dynamic and static stabilizers, of which the triangular fibrocartilage complex (TFCC) is the most important, and the distal interosseous ligament is next in importance. The distal oblique band (DOB) is an identifiable component of the distal interosseous ligament, found in a subset of the population. Our objective was to determine the contribution of the DOB to DRUJ stability in the presence of a disrupted TFCC. METHODS: Twenty-three above-elbow specimens were prepared by removing the TFCC and the DRUJ joint capsule, preserving the distal interosseous ligament and the pronator quadratus. Cadavers were stratified into two groups-those with, and those without a DOB. A bone plate and screws were attached to the ulna; then, a transverse load was applied to failure, creating a diastasis between the radius and ulna. RESULTS: The group with a DOB had a mean load at failure of 160.7 ± 46.5 N. The group without a DOB had a mean load at failure of 148.0 ± 26.3 N. Stiffness prior to failure was 16.9 N/mm in the group with a DOB and 12.4 N/mm in the group without a DOB. CONCLUSIONS: The current results indicate that the DOB may not substantially contribute to DRUJ stability in the presence of a disrupted TFCC. CLINICAL RELEVANCE: Stability of the DRUJ after TFCC injury may not be substantially improved by the presence of a DOB. Thus, the clinical importance of DOB reconstruction remains unclear.

The Association Between Social Determinants of Health and Distal Radius Fracture Outcomes.

PURPOSE: The purpose of this study was to determine if adverse social determinants of health (SDOH) are associated with differential complication rates following surgical fixation of distal radius fractures and assess which SDOH domain (economic, educational, social, health care, or environmental) is most associated with postoperative complications. METHODS: Using a national administrative claims database, we conducted a retrospective cohort analysis of patients undergoing open treatment for an isolated distal radius fracture between 2010 and 2020. Patients were stratified based on the presence/absence of at least one SDOH code and propensity score matched to create two cohorts balanced by age, sex (male or female), insurance type, and comorbidities. Social determinants of health examined included economic, educational, social, health care, and environmental factors. Multivariable logistic regression analyses were performed to assess the isolated effect of SDOH on 90-day and 1-year complication rates. RESULTS: After propensity matching, 57,025 patients in the adverse SDOH cohort and 57,025 patients in the control cohort were included. Patients facing an adverse SDOH were significantly more likely to experience 90-day complications, including emergency department visits (Odds ratio (OR): 3.18 [95% confidence interval (CI): 3.07-3.29]), infection (OR: 2.37 [95% CI: 2.12-2.66]), wound dehiscence (OR: 2.06 [95% CI: 1.72-2.49]), and 1-year complications, including complex regional pain syndrome (OR: 1.35 [95% CI: 1.15-1.58]), malunion/nonunion (OR: 1.18 [95% CI: 1.08-1.29]), and hardware removal (OR: 1.13 [95% CI: 1.07-1.20]). Additionally, patients facing an adverse SDOH had a significantly increased risk of 90-day complications, regardless of fracture severity, and patients with economic and social challenges had the highest odds of both 90-day and 1-year postoperative complications. CONCLUSIONS: Social determinants of health are associated with increased complications following distal radius fracture fixation, even when controlling for demographic and clinical factors. We recommend routine screening for adverse SDOH and inclusion of SDOH data into health records to not only inform quality improvement initiatives and risk adjustment for outcome-based quality measurements but also to allow providers to begin to discuss and address such barriers during the perioperative period. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis II.
