Notch signalling drives synovial fibroblast identity and arthritis pathology.

The synovium is a mesenchymal tissue composed mainly of fibroblasts, with a lining and sublining that surround the joints. In rheumatoid arthritis the synovial tissue undergoes marked hyperplasia, becomes inflamed and invasive, and destroys the joint1,2. It has recently been shown that a subset of fibroblasts in the sublining undergoes a major expansion in rheumatoid arthritis that is linked to disease activity3-5; however, the molecular mechanism by which these fibroblasts differentiate and expand is unknown. Here we identify a critical role for NOTCH3 signalling in the differentiation of perivascular and sublining fibroblasts that express CD90 (encoded by THY1). Using single-cell RNA sequencing and synovial tissue organoids, we found that NOTCH3 signalling drives both transcriptional and spatial gradients-emanating from vascular endothelial cells outwards-in fibroblasts. In active rheumatoid arthritis, NOTCH3 and Notch target genes are markedly upregulated in synovial fibroblasts. In mice, the genetic deletion of Notch3 or the blockade of NOTCH3 signalling attenuates inflammation and prevents joint damage in inflammatory arthritis. Our results indicate that synovial fibroblasts exhibit a positional identity that is regulated by endothelium-derived Notch signalling, and that this stromal crosstalk pathway underlies inflammation and pathology in inflammatory arthritis.

Trends in inpatient versus outpatient upper extremity fracture surgery from 2008 to 2021 and their implications for equitable access: a retrospective cohort study.

PURPOSE: The aim of this study is to describe trends in inpatient and outpatient upper extremity fracture surgery between 2008 and 2021, along with identifying patient factors (age, sex, race, socioeconomic status) associated with outpatient surgery. METHODS: Retrospectively, 12,593 adult patients who underwent upper extremity fracture repair from 2008 to 2021 at one of five urban hospitals in the Northeastern USA were identified. Using Distressed Communities Index (DCI), patients were divided into five quintiles based on their level of socioeconomic distress. Multivariable logistic regression was performed on patients from 2008 to 2019 to identify independent factors associated with outpatient management. RESULTS: From 2008 to 2019, outpatient procedures saw an average increase of 31%. The largest increases in the outpatient management were seen in humerus (132%) and forearm fractures (127%). Carpal and hand surgeries had the lowest percent increase of 8.1%. Clavicle and wrist fractures were independently associated with outpatient management. Older age, male sex, higher Elixhauser comorbidity index, DCI scores in the 4th or 5th quintile, and fractures of the scapula, humerus, elbow, and forearm were associated with inpatient management. During the onset of the COVID-19 pandemic, there was a decrease in outpatient procedures. CONCLUSION: There is a shift toward outpatient surgical management of upper extremity fractures from 2008 to 2021. Application of our findings can serve as an institutional guide to allocate patients to appropriate surgical settings. Moreover, physicians and institutions should be aware of the potential socioeconomic disparities and implement plans to allow for equal access to care.

Collagenase Treatment Versus Needle Fasciotomy for Single-Digit Dupuytren Contractures: A Meta-Analysis of Randomized Controlled Trials.

PURPOSE: The objective of this systematic review and meta-analysis was to synthesize the available randomized controlled trial data comparing needle fasciotomy and collagenase treatment for single-digit Dupuytren contractures with a minimum of 3-year follow-up and determine whether one treatment is superior regarding contracture correction and functional outcomes. METHODS: A systematic review and meta-analysis was conducted by searching four databases for randomized controlled trials investigating the single-digit treatment outcomes for Dupuytren contracture comparing collagenase treatment and needle fasciotomy with a minimum of 3-year follow-up. The risk of bias of included studies was assessed using the Cochrane risk-of-bias tool. A meta-analysis was performed using a random effects model in anticipation of unobserved heterogeneity. The primary outcome measure was contracture recurrence. Secondary outcome measures included final fixed flexion contracture (FFC), Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and Unité Rhumatologique des Affections de la Main (URAM) scores. RESULTS: After screening 264 articles, 4 randomized clinical trials were eligible for final inclusion. One trial had a high risk of bias, and two trials had some concern for bias. The final meta-analysis included 347 patients, 169 who underwent collagenase treatment and 178 who underwent needle fasciotomy. No significant differences were noted between the groups in contracture recurrence, FFC, and URAM scores. The pooled data showed a higher QuickDASH score in the collagenase treatment group compared with the needle fasciotomy group, but the observed difference was less than what would be expected to be clinically relevant. CONCLUSIONS: Needle fasciotomy and collagenase treatment have similar outcomes with regards to contracture recurrence, final FFC, QuickDASH scores, and URAM scores for the single-digit treatment for Dupuytren contracture at a minimum of 3-year follow-up. Relevant factors that may be considered during the shared decision-making process for treatment selection include surgeon and patient preferences, costs of treatment, and the disparate complication profiles of these two treatments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Utility of Routine Pathologic Examination for Fasciectomy for Dupuytren Contracture.

PURPOSE: The objective of this study was to examine the routine pathologic examination of surgical specimens obtained during fasciectomy for Dupuytren contracture. METHODS: A total of 376 consecutive patients who underwent surgical limited fasciectomy with the excised tissue sent for histopathologic evaluation were identified. Patients were excluded for miscoded procedures, cases where no tissue was sent for pathologic review, and excisions of nodules only. Repeat surgeries in the same patient during the study period were excluded. The rates of concordant, discrepant, and discordant diagnoses were reported. Discrepant diagnoses were defined as different clinical diagnosis and pathologic diagnosis that did not change clinical management. Discordant diagnoses were defined as a different clinical diagnosis and a pathologic diagnosis that altered the treatment plan. The reference standard for final clinical decision-making was the pathologic diagnosis. RESULTS: The prevalence of concordant diagnoses was 97.1% (365 of 376), of discrepant diagnoses was 2.9% (11 of 376), and there were no discordant diagnoses. Of 376 patients, 43 underwent previous surgical fasciectomy before the study surgery, and pathologic examination was obtained in 10 of these patients. All 10 patients had concordant diagnoses. CONCLUSIONS: Our results suggest that routine pathologic examination did not alter the future treatment plan for patients who underwent limited fasciectomy. Discrepant diagnoses were encountered infrequently, and rarely in the setting of revision fasciectomy. Discordant diagnoses did not occur. Given the cost associated with pathologic evaluation, this raises the question of whether routine pathologic evaluation is necessary for Dupuytren surgery, where the capability of the treating surgeon to make a clinical diagnosis accurately may render confirmatory pathologic assessment redundant. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

The Environmental Impact of Open Versus Endoscopic Carpal Tunnel Release.

PURPOSE: The environmental impact of common ambulatory hand surgeries has been an area of growing interest in recent years. There were 2 objectives of this study: (1) to quantify the carbon footprint of carpal tunnel surgery and its principal driving components; and (2) to compare the carbon footprints of open carpal tunnel release (oCTR) and endoscopic carpal tunnel release (eCTR). METHODS: We performed a life cycle assessment to quantify the environmental impacts of 2 surgical procedures: oCTR and eCTR. Patients were retrospectively identified by querying the Mass General Brigham institutional billing database. Fourteen oCTR procedures and 14 eCTR procedures in 28 patients were included in the life cycle assessment. The boundaries of the life cycle assessment were the start and end times of the procedures. The environmental impacts were estimated using the carbon footprint, expressed in the equivalent mass of carbon dioxide released into the atmosphere (kgCO2-eq). The facility-related, processing-related, solid waste-related, and total kgCO2-eq were calculated. RESULTS: The average carbon footprint of carpal tunnel release was 83.1 kgCO2-eq and was dominated by processing-related and facilities-related factors. The average carbon footprint of eCTR (106.5 kgCO2-eq) was significantly greater than that of oCTR (59.6 kgCO2-eq). CONCLUSIONS: Endoscopic carpal tunnel release leaves a greater carbon footprint than oCTR, and its environmental impact is dominated by facility-related and central processing-related factors.

Risk Factors for Failure of Nonsurgical Management of Ulnar Shaft Fractures.

PURPOSE: Isolated ulnar shaft fractures are frequently managed nonsurgically. However, rates of nonsurgical treatment failure remain substantial, and risk factors for the failure of nonsurgical management are not well described. This study investigated radiographic and patient-specific risk factors for the failure of nonsurgical management of isolated ulnar shaft fractures. METHODS: A retrospective review of patients with ulnar shaft fractures initially treated nonsurgically was performed at two tertiary referral centers over a 19-year period from 2001 to 2020. Patient- and injury-related variables, surgical interventions, and plain radiographic measurements were recorded. The outcome of interest was failure of nonsurgical management, defined as failure to achieve fracture union nonsurgically within 3 months of injury. RESULTS: One hundred fifty four patients initially treated nonsurgically for isolated ulnar shaft fractures were included. Twenty six patients (17%) experienced failure of nonsurgical management; these included five nonunions, 16 delayed unions, and 10 conversions to surgical management. Patients who experienced failure of nonsurgical management had a higher prevalence of diabetes mellitus, a higher employment rate, and fractures with higher initial median posteroanterior and lateral translations, fracture gap, and angulation; 83% of the patients with an initial fracture gap of ≥4 mm and 41% of the patients with an initial fracture angulation of >10° failed nonsurgical management. CONCLUSIONS: Although most ulnar shaft fractures heal successfully with nonsurgical management, a substantial percentage of these fractures do not. Patients who are currently working, have diabetes mellitus, or have fractures with an initial fracture gap of ≥4 mm or an initial fracture angulation of > 10° may be more likely to fail nonsurgical treatment, although additional studies with larger sample sizes are needed to confirm these associations. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Patient-Perceived Outcomes of Recovery After Trigger Digit Release.

PURPOSE: Trigger finger release (TFR) is one of the most commonly performed hand surgeries; nevertheless, the time until patients subjectively feel recovered has not been well documented. The limited literature on patient perceptions of recovery after any type of surgery has described that patients and surgeons may have differing views on the time until full recovery. Our primary study question was to determine how long it takes for patients to subjectively feel fully recovered after TFR. METHODS: In this prospective study, patients who underwent isolated TFR completed questionnaires before surgery and at multiple time points following surgery until they reported full recovery. Patients completed visual analog scale (VAS) pain scores and QuickDASH (Disabilities of the Arm, Shoulder, and Hand) and were asked if they felt fully recovered at 4 weeks, 6 weeks, and 3, 6, 9, and 12 months. RESULTS: The average time to self-reported full recovery was 6.2 months (SD 2.6), and the median time to self-reported full recovery was 6 months (IQR 4 months). At 12 months, four out of 50 patients (8%) did not feel fully recovered. QuickDASH and VAS pain scores improved significantly from preoperative assessment to final follow-up. All patients reported improvement in both VAS pain scores and QuickDASH scores greater than the minimal clinically important difference between 6 weeks and 3 months after surgery. Higher preoperative VAS and QuickDASH scores were associated with failure to fully recover by 12 months after surgery. CONCLUSIONS: The length of time after surgery until patients felt fully recovered after isolated TFR is longer than the senior authors' expectations. This suggests that patients and surgeons may consider distinctly different parameters when discussing recovery. Surgeons should be aware of this discrepancy when discussing recovery after surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Factors Associated With Implant Removal Following Plate-and-Screw Fixation of Isolated Metacarpal Fractures.

PURPOSE: The incidence of and associated risk factors for implant removal following the plate-and-screw fixation of metacarpal shaft fractures have not been well described. The primary objective of our study was to identify implant-related radiographic parameters associated with implant removal in patients treated with the plate-and-screw fixation of isolated, displaced metacarpal fractures at 2 years of follow-up. The secondary objective of our study was to identify patient-related factors associated with implant removal. METHODS: A retrospective study of all patients who underwent open treatment of a metacarpal fracture with a plate-and-screw construct from January 1, 2000, to April 30, 2019, at 2 level-1 trauma centers was conducted. After the application of exclusion criteria, we identified 138 patients with a single isolated metacarpal fracture of a nonthumb digit treated with open reduction and internal fixation using a plate-and-screw construct. Our study endpoint was the removal of the plate-and-screw construct or a minimum of 2 years of follow-up without the removal of the hardware. Twenty-three patients achieved our study endpoint as determined using their electronic medical records, and 58 additional patients were reached via telephone to confirm their implant removal status. A bivariate analysis was used to screen for factors associated with implant removal, and variables significant in the bivariate screen were included in a multivariable stepwise logistic regression model. RESULTS: Twenty-three out of 81 patients (28%) in our final cohort underwent implant removal by the final follow-up visit. In the logistic regression analysis, the distance between the plate and metacarpophalangeal joint, the distance between the plate and carpometacarpal joint, and active smoking were independently associated with implant removal. CONCLUSIONS: The proximity of metacarpal plates to adjacent joints is associated with subsequent implant removal. Patients may be counseled about the higher risk of implant removal when periarticular metacarpal plating is performed. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

Do Patients Want to Be Involved in Their Carpal Tunnel Surgery Decisions? A Multicenter Study.

PURPOSE: Carpal tunnel syndrome requires multiple decisions during its management, including regarding preoperative studies, surgical technique, and postoperative wound management. Whether patients have varying preferences for the degree to which they share in decisions during different phases of care has not been explored. The goal of our study was to evaluate the degree to which patients want to be involved along the care pathway in the management of carpal tunnel syndrome. METHODS: We performed a prospective, multicenter study of patients undergoing carpal tunnel surgery at 5 academic medical centers. Patients received a 27-item questionnaire to rate their preferred level of involvement for decisions made during 3 phases of care for carpal tunnel surgery: preoperative, intraoperative, and postoperative. Preferences for participation were quantified using the Control Preferences Scale. These questions were scored on a scale of 0 to 4, with patient-only decisions scoring 0, semiactive decisions scoring 1, equally collaborative decisions scoring 2, semipassive decisions scoring 3, and physician-only decisions scoring 4. Descriptive statistics were calculated. RESULTS: Seventy-one patients completed the survey between November 2018 and April 2019. Overall, patients preferred semipassive decisions in all phases of care (median score, 3). Patients preferred equally collaborative decisions for preoperative decisions (median score, 2). Patients preferred a semipassive decision-making role for intraoperative and postoperative decisions (median score, 3), suggesting these did not need to be equally shared. CONCLUSIONS: Patients with carpal tunnel syndrome prefer varying degrees of involvement in the decision-making process of their care and prefer a semipassive role in intraoperative and postoperative decisions. CLINICAL RELEVANCE: Strategies to engage patients to varying degrees for all decisions during the management of carpal tunnel syndrome, such as decision aids for preoperative surgical decisions and educational handouts for intraoperative decisions, may facilitate aligning decisions with patient preferences for shared decision-making.

Association of Economic Well-Being With Comorbid Conditions in Patients Undergoing Carpal Tunnel Release.

PURPOSE: Medical comorbidities have been associated with the development of carpal tunnel syndrome (CTS), severity at the time of presentation, and outcomes of carpal tunnel release (CTR). Socioeconomic factors have also been associated with worse function in patients with CTS at presentation and after surgery. However, the effects of economic well-being on the prevalence of medical comorbidities in patients with CTS have not been well-described. The objective of this study was to determine whether economic well-being is associated with medical comorbidities in a cohort of patients undergoing CTR. METHODS: Patients (n = 1,297) who underwent CTR at a single tertiary care referral center over a 5-year period from July 2008 to June 2013 were retrospectively identified. The exclusion criteria were acute trauma or infection, revision surgery, incomplete medical records, and neoplasm excision. Additionally, patients were excluded if they lacked documented confirmatory or normal electrodiagnostic study findings prior to CTR. Finally, this study comprised a cohort of 892 patients with electrodiagnostic study-confirmed CTS who underwent CTR. The economic well-being of patients was assessed using the Distressed Communities Index. The comorbidities of diabetes mellitus, chronic kidney disease, hypertension, hypothyroidism, cervical radiculopathy, tobacco use, and body mass index were assessed. Bivariate comparisons were used to determine the associations between the tiers of economic well-being and comorbidities. RESULTS: Lower economic well-being was associated with body mass index, diabetes mellitus, chronic kidney disease, and tobacco use in these patients. Although hypertension, hypothyroidism, and cervical radiculopathy were not associated with economic well-being, their comparisons were underpowered. CONCLUSIONS: Patients experiencing economic distress have a higher comorbidity burden, and as such, may be at an increased risk of complications or poorer outcomes. The association between economic well-being and comorbidities in this population suggests the need for a multidisciplinary care model that addresses both compressive neuropathy and the associated economic factors. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Readability of Online Hand Surgery Patient Educational Materials: Evaluating the Trend Since 2008.

PURPOSE: Online patient educational materials have historically been written at a higher-than-recommended sixth grade reading level. The objectives of this study were to assess the readability of online hand surgery patient educational materials from the official online patient resource website of the American Society for Surgery of the Hand (ASSH) and to compare changes in the readability of the current ASSH online patient educational materials with those in 2008 and 2015. METHODS: An internet-based study of all 88 English language patient educational materials on HandCare.org, the official online patient resource website of the ASSH, was performed. The readability of each article was assessed using the Flesch reading ease formula, Flesch-Kincaid grade level, Coleman-Liau index, Gunning-Fog index, and Simple Measure of Gobbledygook grade level. To evaluate the trend in the readability of ASSH online hand surgery patient educational materials, the Flesch-Kincaid grade levels of articles published in 2020 were compared with those of data published in 2008 and 2015. RESULTS: The average Flesch reading ease score of the patient educational materials was 57.6, which is at the high-school reading level. The average reading grade level of patient educational materials ranged from 9.0 to 12.3 depending on the readability metric used. The average Flesch-Kincaid grade level of all the ASSH patient educational materials was 9.8 in 2020, which is significantly better than 10.4 in 2008 but significantly worse than 8.5 in 2015. CONCLUSIONS: Online hand surgery patient educational materials continue to be written for the general public at a higher-than-recommended reading grade level. There has been no substantial improvement in the readability of online hand surgery patient educational materials since 2008. CLINICAL RELEVANCE: Improvements are needed in the readability of online patient educational materials to ensure that patients with all health literacy levels are able to comprehend and benefit from health information.

Implicit and Explicit Factors That Influence Surgeons' Decision-Making for Distal Radius Fractures in Older Patients.

PURPOSE: The purpose of this study was to evaluate factors that influence surgeons' decision-making in the treatment of distal radius fractures in older patients. METHODS: Fourteen clinical vignettes of a 72-year-old patient with a distal radius fracture were sent to 185 orthopedic hand and/or trauma surgeons. The surgeons were surveyed regarding the demographic/practice details, treatment decision (surgical or nonsurgical), and factors that influenced management, including the Charlson Comorbidity Index, functional status, radiographic appearance, and handedness. Multivariable regression analyses were used to assess the effect of both surgeon-described (explicit) and given clinical (implicit) factors on the treatment decision and to evaluate for discrepancies. RESULTS: Sixty-six surgeons completed the survey, and 7 surgeons completed 10-13 vignettes. Surgeons made the explicit determination to pursue nonsurgical treatment based on the presence of comorbidities (odds ratio [OR], 0.02 for surgery; 95% confidence interval [CI], 0.01-0.05), but the observation of the underlying clinical data suggested that the recommendation for surgical treatment was instead based on a higher functional status (OR, 3.54/increase in functional status; 95% CI, 2.52-4.98). Those employed by hospitals/health systems were significantly less likely to recommend surgery than those in private practice (OR, 0.42; 95% CI, 0.23-0.79) CONCLUSIONS: This study demonstrates that the presence of comorbidities, functional status, and practice setting has a significant impact on a surgeon's decision to treat distal radius fractures in older patients. The discrepancy between the surgeon-described factors and underlying clinical data demonstrates cognitive bias. CLINICAL RELEVANCE: Surgeons should be aware of cognitive biases in clinical reasoning and should work through consequential patient decisions using an analytical framework that attempts to reconcile all available clinical data.

The Impact of the Soong Index on Hardware Removal and Overall Reoperation Rates After Volar Locking Plate Fixation of Distal Radius Fractures.

PURPOSE: This study sought to determine the impact of volar plate prominence on reoperation rates after open reduction and internal fixation of distal radius fractures with volar locking plates and to identify other factors associated with removal of hardware (ROH) or a reoperation. METHODS: A retrospective study of patients who underwent distal radius open reduction and internal fixation between 2012 and 2016 at 2 level I trauma centers was conducted. Plate prominence was evaluated using the Soong index at the first postoperative visit. The details of patient demographics, fracture and plate characteristics, complications, and reoperations were recorded. Bivariate and multivariable regression analyses were used to identify factors associated with increased rates of ROH and overall reoperation. RESULTS: A total of 732 (70.2%) of 1,042 patients completed follow-up at an average of 38.2 months, including 34 patients with bilateral operations, yielding 766 distal radius fractures. One hundred sixteen (15.1%) patients underwent reoperation at an average of 12.1 ± 13.6 months after the index surgery. Removal of hardware was the most commonly performed reoperation (77 patients, 10%). The multivariable regression analysis revealed significantly higher rates of ROH in Soong grade 1 or 2 patients (odds ratio 16, 95% CI 5.8-47; odds ratio 44, 95% CI 14-140, respectively) than in Soong grade 0 patients. Plate type, younger age, bilateral injuries, and concomitant procedures at the time of the index operation were all associated with increased risk of ROH. There were significant differences between individual surgeons the in rates of ROH (range 2.1%-22%) and overall reoperation (range 5.2%-36%). Compared with other hand surgeons, fellowship-trained hand surgeons had lower rates of ROH (8% vs 14%, respectively) and overall reoperation (12% vs 22%, respectively). CONCLUSIONS: The rates of ROH and overall reoperation increase with increasing Soong grade. Plate type is independently predictive of future ROH. Older patients and those undergoing open reduction and internal fixation experience lower rates of subsequent reoperation. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

What Factors Are Associated with Reoperation After Operative Treatment of Terrible Triad Injuries?

BACKGROUND: Terrible triad injuries of the elbow, consisting of posterior ulnohumeral joint dislocation with associated fractures of the radial head and coronoid process, are challenging injuries due to the difficulty in restoring stability to the joint surgically while also attempting to allow early ROM to prevent stiffness. Furthermore, complications are both debilitating and relatively common, frequently requiring reoperation. QUESTIONS/PURPOSES: (1) What patient-, injury-, or surgery-related factors are associated with reoperation after surgical treatment of terrible triad injuries of the elbow? (2) What are the most common causes of reoperation after these injuries? METHODS: Between January 2000 and June 2017, we identified 114 patients who had surgery for terrible triad injuries at two tertiary-care referral centers. Of those, 40% (46 of 114) were lost to follow-up before 1 year, and an additional 5% (6 of 114) were excluded because they underwent the index surgery at an outside institution (n = 4) or underwent closed reduction with or without percutaneous pinning (n = 2). That left 62 patients for analysis in this retrospective study with a minimum of 1-year follow-up (median 22 months; range 12 to 65) or who met the endpoint of reoperation before 1 year. During the study period, indications for surgical treatment of terrible triad injuries of the elbow included joint incongruity or instability precluding early ROM. In our study cohort, 45% (28 of 62) underwent reoperation. Indications for reoperation after surgical treatment included stiffness that interfered with activities of daily life, symptomatic prominent hardware, ulnar neuropathy, instability of the elbow joint at rest or with range of motion, and infection. Patient-related (such as age, sex, race), injury-related (for example, ipsilateral extremity fracture, open fracture), and surgery-related factors (for instance, time to surgery, radial head treatment) as well as outcomes were collected by the treating surgeon at the time of follow-up and ascertained using chart review. The primary outcome measure was reoperation after surgical treatment of a terrible triad injury of the elbow. Bivariate analysis was used to assess whether explanatory variables were associated with reoperation after surgical treatment of terrible triad injuries of the elbow. RESULTS: Of the patient-, injury-, and surgery-related factors that were analyzed, only radial head treatment was associated with an increased reoperation risk (p = 0.03). No other variable met criteria for inclusion in our multivariable logistic regression model (p < 0.10), and therefore, a multivariable logistic regression model was not performed. The most common indication for reoperation was stiffness (21% [13 of 62 patients]), followed by symptomatic hardware (18% [11 of 62 patients]), nerve symptoms (ulnar neuropathy 16% [10 of 62 patients] and incisional neuroma 2% [1 of 62 patients]), instability (6% [4 of 62 patients]), and wound problems (infection 2% [1 of 62 patients]). CONCLUSION: The reoperation risk after surgical treatment of terrible triad injuries of the elbow is high. No patient- or injury-related factors were associated with the reoperation risk. Based on our finding, we recommend fixation of radial head fractures in these injuries when feasible and compatible with early postoperative motion, and we suggest the use of radial head excision or arthroplasty as a secondary options. LEVEL OF EVIDENCE: Level III, therapeutic study.

Is Grit Associated with Burnout and Well-being in Orthopaedic Resident and Faculty Physicians? A Multi-institution Longitudinal Study Across Training Levels.

BACKGROUND: Grit has been defined as "perseverance and passion for long-term goals" and is characterized by maintaining focus and motivation toward a challenging ambition despite setbacks. There are limited data on the impact of grit on burnout and psychologic well-being in orthopaedic surgery, as well as on which factors may be associated with these variables. QUESTIONS/PURPOSES: (1) Is grit inversely correlated with burnout in orthopaedic resident and faculty physicians? (2) Is grit positively correlated with psychologic well-being in orthopaedic resident and faculty physicians? (3) Which demographic characteristics are associated with grit in orthopaedic resident and faculty physicians? (4) Which demographic characteristics are associated with burnout and psychologic well-being in orthopaedic resident and faculty physicians? METHODS: This study was an institutional review board-approved interim analysis from the first year of a 5-year longitudinal study of grit, burnout, and psychologic well-being in order to assess baseline relationships between these variables before analyzing how they may change over time. Orthopaedic residents, fellows, and faculty from 14 academic medical centers were enrolled, and 30% (335 of 1129) responded. We analyzed for the potential of response bias and found no important differences between sites in low versus high response rates, nor between early and late responders. Participants completed an email-based survey consisting of the Duckworth Short Grit Scale, Maslach Burnout Inventory-Human Services (Medical Personnel) Survey, and Dupuy Psychological Well-being Index. The Short Grit Scale has been validated with regard to internal consistency, consensual and predictive validity, and test-retest stability. The Psychological Well-being Index has similarly been validated with regard to reliability, test-retest stability, and internal consistency, and the Maslach Burnout Inventory has been validated with regard to internal consistency, reliability, test-retest stability, and convergent validity. The survey also obtained basic demographic information such as survey participants' age, gender, race, ethnicity, marital status, current year of training or year in practice (as applicable), and region of practice. The studied population consisted of 166 faculty, 150 residents, and 19 fellows. Beyond the expected age differences between sub-populations, the fellow population had a higher proportion of women than the faculty and resident populations did. Pearson correlations and standardized ß coefficients were used to assess the relationships of grit, burnout, psychologic well-being, and continuous participant characteristics. RESULTS: We found moderate, negative relationships between grit and emotional exhaustion (r = -0.30; 95% CI -0.38 to -0.21; p < 0.001), depersonalization (r = -0.34; 95% CI -0.44 to -0.23; p < 0.001), and the overall burnout score (r = -0.39; 95% CI -0.48 to -0.31; p < 0.001). The results also showed a positive correlation between grit and personal accomplishment (r = 0.39; 95% CI 0.29 to 0.48; p < 0.001). We also found a moderate, positive relationship between grit and psychologic well-being (r = 0.39; 95% CI 0.30 to 0.49; p < 0.001). Orthopaedic surgeons with 21 years or more of practice had higher grit scores than physicians with 10 to 20 years of practice. Orthopaedic surgeons in practice for 21 years or more also had lower burnout scores than those in practice for 10 to 20 years. Married physicians had higher psychologic well-being than unmarried physicians did. CONCLUSION: Among orthopaedic residents, fellows, and faculty, grit is inversely related to burnout, with lower scores for emotional exhaustion and depersonalization and higher scores for personal accomplishment as grit increases. CLINICAL RELEVANCE: The results suggest that grit could be targeted as an intervention for reducing burnout and promoting psychologic well-being among orthopaedic surgeons. Other research has suggested that grit is influenced by internal characteristics, life experiences, and the external environment, suggesting that there is potential to increase one's grit. Residency programs and faculty development initiatives might consider measuring grit to assess for the risk of burnout, as well as offering curricula or training to promote this psychologic characteristic.

Correlation Between Social Media Postings and Academic Citations of Hand Surgery Research Publications.

PURPOSE: The relationship between social media postings and academic citations of hand surgery research publications is not known. The objectives of this study were (1) to quantify adoption of social media for the dissemination of original research publications by 3 hand surgery journals, and (2) to determine the correlation between social media postings and academic citations in recent hand surgery research publications. METHODS: An Internet-based study was performed of all research articles from 3 hand surgery journals published from January 2018 to March 2019. A final sample of 472 original full-length scientific research articles was included. For each article, the total number of social media postings was determined using Twitter, as well as the number of tweets, number of retweets, number of tweets from an official outlet, and number of tweets from an author. The number of academic citations for each article was determined using Google Scholar. RESULTS: Average number of academic citations per article was 3.9. Average number of social media posts per article was 3.2, which consisted of an average of 1.3 tweets and 1.9 retweets per article. The number of academic citations per article was weakly correlated with the number of social medial postings, the number of tweets, and the number of retweets. The number of tweets from an official outlet and from an author were weakly correlated with academic citation. CONCLUSIONS: In the early adoption of social media for the dissemination of hand surgery research, there is a weak correlation between social media posting of hand surgery research and academic citation. CLINICAL RELEVANCE: Future studies are needed to assess whether social media posting of hand surgery research results in academic citations at the longer time intervals necessary for research publication maturity.

Dupuytren Contractures: An Update of Recent Literature.

Dupuytren disease is a fibroproliferative disorder that affects the palmar fascia of the hand and results in varying degrees of nodule and cord formation. Over time, patients may develop progressive contractures, impairing their ability to type, to perform with fine instruments, or to participate in social activities such as shaking hands. Treatment options for Dupuytren contractures include needle aponeurotomy (NA), injection of collagenase Clostridium histolyticum (CCH) with manipulation of the digits, and surgical fasciectomy. Over the past decade, the use of CCH has increased. Recent studies have provided additional data regarding the pathophysiology, indications, outcomes, and costs associated with the treatment for Dupuytren contractures, and this review highlights these advances.

Factors Associated With Surgical Treatment of Nondisplaced or Minimally Displaced Scaphoid Waist Fractures.

PURPOSE: To determine whether there are identifiable factors associated with the surgical treatment of nondisplaced or minimally displaced scaphoid waist fractures. METHODS: We identified 50 patients who underwent nonsurgical treatment and 67 patients who underwent surgical treatment of nondisplaced or minimally displaced scaphoid waist fractures at 2 tertiary care referral centers in a single metropolitan area in the United States between January 2010 and March 2019. Bivariate analysis was used to screen for factors associated with surgical treatment. Multivariable stepwise logistic regression was used to determine factors associated with surgical treatment of a nondisplaced or minimally displaced scaphoid fracture. RESULTS: Multivariable logistic regression analysis showed that male sex (odds ratio = 2.80; 95% confidence interval, 1.20-6.52) and employed status (odds ratio = 3.12, 95% confidence interval, 1.24-7.85) were associated with surgical treatment of nondisplaced or minimally displaced scaphoid waist fractures. CONCLUSIONS: Male and employed patients have increased odds of undergoing scaphoid surgery for nondisplaced or minimally displaced waist fractures compared with female and unemployed patients. These differences may represent patient preference, surgeon counseling, or a combination. Further study is needed to understand the etiology of this sex difference. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Three-Dimensional Printing in Hand Surgery.

The medical application of 3-dimensional printing technology has evolved in the last decade, with an increasing variety of uses in hand surgery. The ability for patient-specific design, rapid prototyping, and low cost of production of 3-dimensional printed materials has led to this rise in clinical applications, both for common procedures and complex reconstructions. Within hand surgery, 3-dimensional printing can be applied in several broad categories: to construct patient-specific models for preoperative planning, to design orthotics and prosthetics to meet specific patient demands, to create patient-specific aids for intraoperative use, to generate patient-specific hardware and prostheses for implantation, and for applications for trainee education.

Limited Fasciectomy Versus Collagenase Clostridium histolyticum for Dupuytren Contracture: A Propensity Score Matched Study of Single Digit Treatment With Minimum 5 Years of Telephone Follow-Up.

PURPOSE: The purpose of this study was to compare reintervention and perceived recurrence, with minimum 5 years of telephone follow-up, after limited fasciectomy or collagenase Clostridium histolyticum (CCH) in the treatment of Dupuytren contracture affecting a single digit. METHODS: We performed a retrospective cohort study of 48 patients with single digit treatment who underwent limited surgical fasciectomy at one hospital and 111 patients who underwent CCH treatment at a second hospital from 2010 to 2013. Patients were contacted by telephone about reintervention and perceived recurrence. Average length of telephone follow-up was 7.3 years in the CCH group and 7.4 years in the surgery group. The 2 groups were compared using 2 methods to control for potential confounding bias: (1) propensity score matching and (2) multivariable analysis accounting for potential confounders. RESULTS: After propensity score matching, there were 44 patients in each group with similar disease and demographic characteristics. Rates of reintervention and perceived recurrence were significantly higher in the CCH group than the surgery group at a minimum of 5 years following treatment. CONCLUSIONS: Long-term overall reintervention and perceived recurrence following treatment of Dupuytren contracture affecting a single digit were higher with CCH treatment than surgical fasciectomy when comparing groups with similar baseline characteristics. Our findings may be used to counsel patients on the durability of the outcomes of treatment when considering treatment options for Dupuytren contractures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
