Abstract
INTRODUCTION We evaluated the subjective donor-site morbidity and quality of life in patients with a free fibula flap (FFF) reconstruction in terms of self-reported symptoms, function and quality of life, and we compared inclusion vs. exclusion of the flexor hallucis longus (FHL) muscle in the graft, primary wound closure vs. skin graft and the occurrence vs. absence of donor-site complications. METHODS In this cross-sectional study, patients who underwent a mandibula or maxilla reconstruction with a FFF between 2011 and 2021, were included. Symptoms and function were measured with the Foot and Ankle Outcome Score (FAOS) and quality of life with both FAOS and a Visual Analogue Scale (VAS). RESULTS Thirty-four patients were included in the analyses (mean age 59 years, 59% males). Most patients underwent a mandibular reconstruction for a malignancy. The median FAOS domain scores ranged between 92.9 (interquartile range (IQR) 77.7-100.0) and 100.0 (IQR 88.2-100.0) points, and the median VAS score was 86.5 points. No statistically significant differences were found between inclusion vs. exclusion of the FHL, primary wound closure vs. graft and occurrence vs. absence of donor-site complications. An unfavorable trend was seen for inclusion of the FHL in the flap on recreational functioning, and quality of life. CONCLUSION Patients who underwent a FFF experience little donor-site morbidity and high quality of life, as measured by FAOS and VAS.

Abstract
BACKGROUND Patients with Dupuytren's disease (DD) are mostly surgically treated by percutaneous needle fasciotomy (PNF) or limited fasciectomy (LF), but data on time intervals to retreatment is lacking. We aimed to estimate the risk of retreatment within certain time periods after treatment with PNF and LF. METHODS We used data of participants of a cohort study on the course of DD who were treated only with PNF or LF. Our primary outcome measure was time to retreatment of DD. We included sex, age at first treatment and having a first degree relative with DD as confounders in our analysis. We applied a bivariate gamma frailty model to estimate the risk of retreatment within 1,3,5, 10 and 20 years after treatment with PNF and LF. RESULTS The time to retreatment was significantly shorter after treatment with PNF than after LF (Wald test 7.56, p<0.001). The estimated 10-year risk of retreatment for men who underwent their first treatment at a younger age and with a first degree relative with DD was 97% after PNF and 32% after LF. The estimated 10-year risk for women who underwent their first treatment at an older age without a first degree relative with DD was 20% after PNF and 6% after LF. CONCLUSIONS Our results show that the patients treated with PNF have a higher risk of retreatment. The results of this study could contribute to individualized information on the treatment durability in the future, which would improve patient counseling about the expected retreatment needs.

Abstract
OBJECTIVE(S) To explore learning effects when applying the clinician-graded electronic facial function scale (eFACE) and the Sunnybrook Facial Grading System (Sunnybrook). METHODS Surgeons, facial rehabilitation therapists, and medical students were randomly allocated to the eFACE (n = 7) or Sunnybrook (n = 6) and graded 60 videos (Massachusetts Eye and Ear Infirmary open-source standard set); 10 persons with normal facial function and 50 patients with a wide variation of facial palsy severity. Participants received an introduction and individual feedback after each set of 10 videos. Scores were compared to the reference score provided with the set. Multilevel analysis was performed to analyze learning effect. RESULTS A learning effect was only found for the eFACE, with significant difference scores in set 1 and 2 compared to set 6, and no significant difference scores in the following sets. The difference score was associated with the reference score (severity of facial palsy) for eFACE (β = -0.19; SE = 0.04; p < 0.001) and Sunnybrook (β = -0.15; SE = 0.04; p < 0.001). Age of participants was also associated with the difference score in the eFACE group (β = 0.18; SE = 0.03; p < 0.001). No differences in scores were found between groups of participants. CONCLUSION The eFACE showed a learning effect of feedback while the Sunnybrook did not. LEVEL OF EVIDENCE NA Laryngoscope, 2024.

Abstract
Hand surgeons have the potential to improve patient care, both with their own research and by using evidenced-based practice. In this first part of a two-part article, we describe key steps for the analysis of clinical data using quantitative methodology. We aim to describe the principles of medical statistics and their relevance and use in hand surgery, with contemporaneous examples. Hand surgeons seek expertise and guidance in the clinical domain to improve their practice and patient care. Part of this process involves the critical analysis and appraisal of the research of others.

Abstract
We studied 30 healthy volunteers (60 arms), categorized into three age groups with equal numbers to verify if a 22 MHz compared with a 15 MHz ultrasound transducer has additional value for studying the intraneural architecture of the ulnar nerve throughout its course. At six sites, there were no differences in cross-sectional area measurements between the two transducers. With both, the cross-sectional area was significantly larger at the medial epicondyle compared with the other sites and smaller at the mid-forearm and Guyon's canal compared with the mid-upper arm. With higher age the cross-sectional area significantly increased. Significantly more fascicles were visible distal to the medial epicondyle compared with more proximal sites, as well as in men compared with women. Finally, higher body weight was related to a significantly smaller number of fascicles being seen. A 22 MHz transducer depicts more details of the intraneural architecture than a 15 MHz transducer. Our data can be used as normative data or reference values in analysing ulnar nerve pathology.Level of evidence: II.

Abstract
BACKGROUND Web-based patient-reported outcome measures (PROMs) could help surgeons remotely assess the need for examination and subsequent treatment of patients with Dupuytren disease (DD). The authors studied whether the Unité Rhumatologique des Affections de la Main (URAM) and the Michigan Hand Questionnaire (MHQ) could predict DD treatment. METHODS In this prospective cohort study, the authors compared MHQ and URAM scores of treated patients with those of untreated patients. For the treatment group, the authors selected a score closest to 1 year before treatment. For controls, the authors randomly selected a score. The authors also tested the predictive value of a 1-year change score between 15 months and 6 weeks before treatment. The primary outcome measure was DD treatment. The predictive value was determined using the area under the curve (AUC). An AUC greater than 0.70 was considered good predictive ability; 0.70 to 0.50, poor predictive ability; and less than 0.50, no predictive ability. RESULTS The authors included 141 patients for the MHQ analysis and 145 patients for the URAM analysis. The AUC of the MHQ and URAM scores measured 1 year before treatment were 0.80 (95% CI, 0.71 to 0.88) and 0.75 (95% CI, 0.68 to 0.82), respectively. The 1-year change score resulted in an AUC less than 0.60 for both questionnaires. CONCLUSIONS The results show that both the MHQ and URAM score measured around 1 year before treatment can predict treatment for DD. If future studies show that telemonitoring of patients with DD with PROMs is also cost-effective, web-based PROMs could optimize patient care and effectiveness of DD treatment.

Abstract
BACKGROUND The shift of focus towards disease-controlling treatments to prevent DD progression at an early stage underlines the need for objective and reliable measurements that can monitor and predict the course of disease. Ultrasound has been studied as a potential tool for this purpose. This study examined to what extent echogenicity of early DD nodules predicts clinical progression. METHODS Sonographic assessments of Dupuytren's nodules were performed by the same observer on 151 participants as part of an ongoing prospective cohort study on the course of DD. Echogenicity was assessed by determining the greyness of a nodule relative to the surrounding tissue, using ImageJ software. Progression of disease was defined as 1) an increase in total passive extension deficit (TPED) of ≥15 degrees and 2) surgical intervention of the examined ray, both occurring after the sonographic assessment. The associations between echogenicity and time to progression were estimated using Cox-regression models. RESULTS The association between echogenicity and time to TPED progression showed that for every additional decrease of 1% in relative greyness (darker image) of a nodule, the risk of TPED progression during follow-up increases by 3.4% (hazard ratio [HR] = 0.966, 95% confidence interval [CI]: 0.935-0.966). Similarly, echogenicity was also associated with time to surgical intervention (HR = 0.967, 95% CI: 0.938-0.997), which indicates a higher risk for surgery during follow-up for darker nodules. CONCLUSIONS These results suggest that echogenicity is predictive of the prognosis of the early stages of DD and might potentially be used as a prognostic imaging biomarker in the future.

Abstract
OBJECTIVES Dupuytren's disease (DD) is a fibroproliferative disorder of the hands, characterised by the development of fibrous nodules and cords that may cause disabling contractures of the fingers. The role of manual work exposure in the aetiology of DD is controversial. We investigated whether current occupational exposure to manual work is associated with DD, and if there is a dose-response relationship. METHODS In this population-based cohort analysis, we used data from the UK Biobank cohort. Our primary outcome was the presence of DD. The exposure of interest was manual work, measured for each participant in two different ways to allow two independent analyses to be undertaken: (1) the current manual work status of the occupation at the time of recruitment, and (2) a cumulative manual work exposure score, calculated based on the occupational history. We performed propensity score matching and applied a logistic regression model. RESULTS We included 196 265 participants for the current manual work analysis, and 96 563 participants for the dose-response analysis. Participants whose current occupation usually/always involved manual work were more often affected with DD than participants whose occupation sometimes/never involved manual work (OR 1.29, 95% CI 1.12 to 1.49, p<0.001). There was a positive dose-response relationship between cumulative manual work exposure score and DD. Each increment in cumulative work exposure score increased the odds by 17% (OR 1.17, 95% CI 1.08 to 1.27, p<0.001). CONCLUSIONS Manual work exposure is a risk factor for DD, with a clear dose-response relationship. Physicians treating patients should recognise DD as a work-related disorder and inform patients accordingly.

Abstract
This study aimed to determine the association between the echogenicity of Dupuytren's disease nodules and myofibroblast load, and between echogenicity and nodule hardness. Thirty-eight nodules were assessed sonographically. The echogenicity of nodules was measured objectively with Image J (grey-value) and subjectively by visual inspection (hypo-, mixed and hyper-echogenicity). These findings were compared with myofibroblast load measured by histopathological analysis. In a different cohort, 97 nodules were assessed for grey-value and nodule hardness using a tonometer. There was a moderate, significant, negative association between grey-value and myofibroblast load and the subjective visual measurements corresponded to this finding. There was also a moderate, significant, negative association between grey-value and nodule hardness. Ultrasound and tonometry may be useful in the selection of patients for possible future preventive treatments.

Abstract
Importance Understanding how the quality of life of adults (≥18 years) with peripheral facial palsy can be estimated using clinician measures of facial function and patient-reported variables might aid in counseling patients and in conducting research. Objectives To analyze associations between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy, compare associations between facial function and the physical and social functions of quality of life, and examine factors that might influence the associations. Data Sources A literature search was conducted in PubMed, Embase, CINAHL, Web of Science and PsycInfo on June 4, 2020, with no restrictions on the start date. Study Selection Twenty-three studies reporting an association between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy were included. Facial function instruments included the House-Brackmann, Sunnybrook Facial Grading System, and electronic clinician-graded facial function assessment. Quality-of-life instruments included the Facial Disability Index and Facial Clinimetric Evaluation Scale. Data Extraction and Synthesis Data extraction and qualitative synthesis were performed according to the Meta-analysis of Observational Studies in Epidemiology guidelines. Record screening, data extraction, and quality assessments were done by 2 researchers independently. Data were pooled using random-effects models. Main Outcomes and Measures The main outcome was the association between facial function and quality of life, quantified by Pearson r, Spearman ρ, or regression analysis. Results In total, 23 studies (3746 participants) were included. In the 21 studies that reported on the sex of the cohorts, there were 2073 women (57.3%). Mean or median age ranged from 21 to 64 years and mean or median duration of palsy ranged from newly diagnosed to 12 years. Bell palsy (n = 1397), benign tumor (n = 980), and infection (n = 257) were the most common etiologic factors. Pooled correlation coefficients were 0.424 (95% CI, 0.375-0.471) to 0.533 (95% CI, 0.447-0.610) between facial function and Facial Clinimetric Evaluation Scale total, 0.324 (95% CI, 0.128-0.495) to 0.397 (95% CI, 0.242-0.532) between facial function and Facial Clinimetric Evaluation Scale social function, 0.423 (95% CI, 0.322-0.514) to 0.605 (95% CI, -0.124-0.910) between facial function and Facial Disability Index physical function, and 0.166 (95% CI, 0.044-0.283) to 0.208 (95% CI, 0.031-0.373) between facial function and Facial Disability Index social function. Conclusions and Relevance Associations noted in this systematic review and meta-analysis were overall low to moderate, suggesting that only a small part of quality of life is explained by facial function. Associations were higher between facial function and physical function than social function of quality of life.

Abstract
Objective(s): To interpret change in quality-of-life scores in facial palsy patients by calculating the smallest detectable change (SDC) and minimal important change (MIC) for the Facial Disability Index (FDI), Facial Clinimetric Evaluation (FaCE) scale, and Synkinesis Assessment Questionnaire (SAQ). Materials and Methods: The SDC, for individuals and groups, was calculated using previously collected test-retest data (2-week interval). The MIC (predictive modeling method) was calculated in a second similar facial palsy population using two measurements (1-1.5-year interval) and an anchor question assessing perceived change. Results: SDCindividual of FaCE was 17.6 and SAQ was 28.2. SDCgroup of FaCE was 2.9 and SAQ was 4.6 (n = 62). Baseline FaCE and SAQ scores were 43.3 (interquartile range [IQR]: 35.8;55.0) and 51.1 (IQR: 32.2;60.0), respectively. MIC for important improvement of FDI physical/social function, FaCE total, and SAQ total were 4.4, 0.4, 0.7, and 2.8, respectively (n = 88). MIC for deterioration was 8.2, -1.8, -8.5, and 0.6, respectively. Baseline scores were 70.0 (IQR: 60.0;80.0), 76.0 (68.0;88.0), 55.0 (IQR: 40.0;61.7), and 26.7 (IQR: 22.2;35.6), respectively. Number of participants reporting important change for the different questionnaires ranged from 3 to 23 per subscale. Conclusion: Interpreting change scores of the FDI, FaCE, and SAQ is appropriate for groups, but for individual patients it is limited by a substantial SDC.

Abstract
AIMS With novel promising therapies potentially limiting progression of Dupuytren's disease (DD), better patient stratification is needed. We aimed to quantify DD development and progression after seven years in a population-based cohort, and to identify factors predictive of disease development or progression. METHODS All surviving participants from our previous prevalence study were invited to participate in the current prospective cohort study. Participants were examined for presence of DD and Iselin's classification was applied. They were asked to complete comprehensive questionnaires. Disease progression was defined as advancement to a further Iselin stage or surgery. Potential predictive factors were assessed using multivariable regression analyses. Of 763 participants in our original study, 398 were available for further investigation seven years later. RESULTS We identified 143/398 (35.9%) participants with DD, of whom 56 (39.2%) were newly diagnosed. Overall, 20/93 (21.5%) previously affected participants had disease progression, while 6/93 (6.5%) patients showed disease regression. Disease progression occurred more often in patients who initially had advanced disease. Multivariable regression analyses revealed that both ectopic lesions and a positive family history of DD are independent predictors of disease progression. Previous hand injury predicts development of DD. CONCLUSION Disease progression occurred in 21.5% of DD patients in our study. The higher the initial disease stage, the greater the proportion of participants who had disease progression at follow-up. Both ectopic lesions and a positive family history of DD predict disease progression. These patient-specific factors may be used to identify patients who might benefit from treatment that prevents progression. Cite this article: Bone Joint J 2021;103-B(4):704-710.

Abstract
Importance Knowledge of factors associated with health-related quality of life in patients with facial palsy may aid in better interpreting outcomes of research and treatment. Objective To identify factors associated with health-related quality of life in patients with facial palsy. Design, Setting, and Participants The inclusion period for participants in this cross-sectional study at the University Medical Center Groningen, a tertiary referral center for facial reanimation surgery, was March 1 to June 1, 2019. Patients aged at least 18 years with facial palsy who had undergone surgery for facial palsy between January 1, 2007, and January 1, 2018, and patients visiting the outpatient clinic of the University of Groningen Department of Plastic Surgery for their facial palsy between March 1 and June 1, 2019, were also asked to participate. Of 276 patients invited, 145 gave informed consent. Twenty patients did not respond after consent, 3 patients withdrew from the study, and 1 patient was wrongly included. Main Outcomes and Measures Health-related quality of life was measured using the Facial Clinimetric Evaluation Scale and the Facial Disability Index (physical score and social score). Facial function was assessed with the Sunnybrook Facial Grading System. Other variables were investigated using validated questionnaires, including the Duke University Religion Index, Ten-Item Personality Inventory, and Hospital Anxiety and Depression Scale. Multivariable linear regression analyses with stepwise backward selection were performed to identify associations with health-related quality of life. Because 44 Sunnybrook composite scores were missing, a sensitivity analysis was performed that excluded the Sunnybrook composite scores from the multivariable analysis. Results In total, 121 patients with facial palsy were included; their median age was 62 years (interquartile range, 48-71 years), and 63 (52%) were women. Sunnybrook composite score (β = 0.4; 95% CI, 0.2-0.5), extraversion (β = 2.6; 95% CI, 0.4-4.8), and anxiety (β = -2.4; 95% CI, -4.1 to -0.8) were associated with the Facial Clinimetric Evaluation Scale total score (R2 = 0.380; 95% CI, 0.212-0.548). The Sunnybrook composite score was associated with the Facial Disability Index physical score (β = 0.2; 95% CI, 0.0-0.4) (R2 = 0.084; 95% CI, -0.037 to 0.205). Bilateral facial palsy (β = -21.2; 95% CI, -32.3 to -10.1), extraversion (β = 2.7; 95% CI, 1.3-4.1), conscientiousness (β = 2.7; 95% CI, 0.2-5.2), emotional stability (β = 3.3; 95% CI, 1.7-4.8), and depression (β = -1.3; 95% CI, -2.5 to -0.1) were associated with the Facial Disability Index social score (R2 = 0.400; 95% CI, 0.262-0.538). In the sensitivity analysis, the Sunnybrook composite score was associated with age (Spearman ρ = -0.252). Conclusions and Relevance Bilateral facial palsy, age, severity of facial palsy, mental distress, and personality traits should be taken into account in future research and treatment of patients with facial palsy.

Abstract
PURPOSE In the future, it is expected that treatment of Dupuytren disease (DD) may shift toward control of early disease. Ultrasound might be an accurate method to measure the outcome of such treatment. The aim of this study was to assess the reliability of sonographic measurement of palmar nodules. METHODS Fifty patients with nodules characteristic for early disease were assessed with ultrasound by 2 observers. Four different aspects of DD nodules were measured in the transversal and sagittal planes, width, depth, circumference, and area. The intra- and interobserver reliabilities were calculated using the intraclass correlation coefficient (ICC). The standard error of measurement (SEM) and the smallest detectable change (SDC) were also calculated for each aspect. RESULTS The intraobserver reliability was good (ICC, 0.724 [0.562-0.833] to 0.886 [0.808-0.934]), except for width in the sagittal direction (ICC, 0.671 [0.484-0.799]). The interobserver reliability was moderate (ICC, 0.385 [0.126-0.596] to 0.757 [0.538-0.869]). The intraobserver ICCs of area were highest (transverse, 0.847 [0.744-0.893]; sagittal, 0.886 [0.808-0.934]). The SEM and SDC of area were 6.1 and 16.9 mm2 in the transverse and 8.0 and 22.2 mm2 in the sagittal plane. CONCLUSIONS The intraobserver reliability of sonographic assessment of DD nodules is good. The measurement of area is the most reliable and is, therefore, recommended for future studies. However, even single-observer measurements have a clear dispersion, and a change beyond 16.9 (61%) and 22.2 mm2 (79%) has to be observed in the transverse and sagittal planes, respectively, before it can be considered as regression or progression. CLINICAL RELEVANCE Repeated ultrasonographic measurements in DD should ideally be done by a single observer, using area of the nodule in the sagittal plane. Change beyond 16.9 (transverse) and 22.2 (sagittal) mm2 can be considered as a real change in nodule size.

Abstract
BACKGROUND As treatment of Dupuytren disease (DD) is expected to shift towards prevention of progression, the use of imaging in patients with DD becomes more important. In this systematic review an overview is given of the different methods for and applications of imaging for DD that have been described. METHODS The MEDLINE and EMBASE databases were searched for articles reporting the use of imaging in patients with DD, published before May 17, 2018. Studies were systematically examined in two rounds by two observers according to the PRISMA systematic. All studies containing original data on imaging for DD were considered for inclusion. RESULTS Three hundred and seven unique studies were identified, of which 23 were included in the study. Only studies on the use of ultrasound (US) and magnetic resonance imaging (MRI) were identified. Broadly, articles could be divided into 5 categories. Seven studies were found on diagnosis, two on measurement of disease extent, four on measurement of disease activity, seven on guidance of minimally invasive procedures and five studies on evaluation of treatment. According to the Oxford CEBM, the levels of evidence were low, ranging from level 3 to 5. CONCLUSIONS A variety of applications for US and MRI for patients with DD has been described. Based on the results of this review, the largest value for imaging lies in the measurement of disease activity and the follow-up of treatment of patients with early stage disease. Unfortunately, the overall level of evidence of the available literature was low. Future research is necessary to define the exact value of US and MRI in the management of patients with DD.

Abstract
UNLABELLED Data of a prospective longitudinal cohort study including 233 Dupuytren's patients was used to determine: (1) whether the Unité Rhumatologique des Affections de la Main scale and Michigan Hand outcomes Questionnaire can detect change in hand function due to Dupuytren's disease progression and to compare their abilities; (2) the concurrent validity, reliability, responsiveness and interpretability of the Dutch Unité Rhumatologique des Affections de la Main. The Unité Rhumatologique des Affections de la Main and Michigan Hand outcomes Questionnaire had comparable measurement properties, and were both able to distinguish participants with disease progression from those without progression (resp. U = 1252.5, p = 0.008, and U = 1086.0, p < 0.001), but only at a group level. Individual cases of progression could not be detected using these outcome measures, as indicated by the fact that the smallest detectable change was larger than the minimal important change, and area under the receiver operating curve (AUC) values of 0.75 for Michigan Hand outcomes Questionnaire and 0.67 for Unité Rhumatologique des Affections de la Main.

Abstract
BACKGROUND/AIM Dupuytren disease is a fibroproliferative hand condition. The role of exposure to vibration as a risk factor has been studied with contradictory results. Since field hockey is expected to be a strong source of hand-arm vibration, we hypothesised that long-term exposure to field hockey is associated with Dupuytren disease. METHODS In this cross-sectional cohort study, the hands of 169 male field hockey players (IQR: 65-71 years) and 156 male controls (IQR: 59-71 years) were examined for signs of Dupuytren disease. Details about their age, lifestyle factors, medical history, employment history and leisure activities were gathered. Prior to the analyses, the groups were balanced in risk factors using propensity score matching. The association between field hockey and Dupuytren disease was determined using a subject-specific generalised linear mixed model with a binomial distribution and logit link function (matched pairs analysis). RESULTS Dupuytren disease was observed in 51.7% of the field hockey players, and in 13.8% of the controls. After propensity score matching, field hockey playing as dichotomous variable, was associated with Dupuytren disease (OR=9.42, 95% CI 3.01 to 29.53). A linear dose-response effect of field hockey (hours/week x years) within the field hockey players could not be demonstrated (OR=1.03, 95% CI 0.68 to 1.56). DISCUSSION We found that field hockey playing has a strong association with the presence of Dupuytren disease. Clinicians in sports medicine should be alert to this less common diagnosis in this sport.
