Abstract
PURPOSE Dorsal wrist ganglions are treated commonly with aspiration, or open or arthroscopic excision in operating room (OR) or procedure room (PR) settings. As it remains unclear which treatment strategy is most cost-effective in yielding cyst resolution, our purpose was to perform a formal cost-minimization analysis from the societal perspective in this context. METHODS A microsimulation decision analytic model evaluating 5 treatment strategies for dorsal wrist ganglions was developed, ending in either resolution or a single failed open revision surgical excision. Strategies included immediate open excision in the OR, immediate open excision in the PR, immediate arthroscopic excision in the OR, or 1 or 2 aspirations before each of the surgical options. Recurrence and complications rates were pooled from the literature for each treatment type. One-way sensitivity and threshold analyses were performed. RESULTS The most cost-minimal strategy was 2 aspiration attempts before open surgical excision in the PR setting ($1,603 ± 1,595 per resolved case), followed by 2 aspirations before open excision in the OR ($1,969 ± 2,165 per resolved case). Immediate arthroscopic excision was the costliest strategy ($6,539 ± 264 per resolved case). Single aspiration preoperatively was more cost-minimal than any form of immediate surgery ($2,918 ± 306 and $4,188 ± 306 per resolved case performed in the PR and OR, respectively). CONCLUSIONS From the societal perspective, performing 2 aspirations before surgical excision in the PR setting was the most cost-minimal treatment strategy, although in reference to surgeons who do not perform this procedure in the PR setting, open excision in the OR was nearly as cost-effective. As patient preferences may preclude routinely performing 2 aspirations, performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglions treatment.

Abstract
PURPOSE Scaphotrapeziotrapezoid (STT) arthrodesis surgery is used for various types of wrist pathologies. The objective of our study was to perform a systematic review of complications and outcomes after STT arthrodesis. METHODS Several major databases were used to perform a systematic literature review in order to obtain articles reporting complications and outcomes following STT arthrodesis. The primary purpose was to identify rates of nonunion and conversion to total wrist arthrodesis. Secondary outcomes included wrist range of motion, grip strength, and Disabilities of the Arm Shoulder and Hand scores. A multivariable analysis was performed to evaluate factors associated with the primary and secondary outcomes of interest. RESULTS Out of the 854 records identified in the primary literature search, 30 studies were included in the analysis. A total of 1,429 procedures were performed for 1,404 patients. The pooled nonunion rate was 6.3% (95% CI, 3.5-9.9) and the rate of conversion to total wrist arthrodesis following the index STT was 4.2% (95% CI, 2.2-6.7). The mean pooled wrist flexion was 40.7° (95% CI, 30.8-50.5) and extension was 49.7° (95% CI, 43.5-55.8). At final follow-up, the mean pooled grip strength was 75.9% (95% CI, 69.3-82.5) of the nonsurgical contralateral hand. Compared with all other known indications, Kienbock disease had a statistically significant lower nonunion rate (14.1% vs 3.3%, respectively). Mixed-effects linear regression using patient-level data revealed that increasing age was significantly associated with complications, independent of occupation and diagnosis. CONCLUSIONS Our study demonstrated a low failure rate and conversion to total wrist arthrodesis after STT arthrodesis and acceptable postoperative wrist range of motion and strength when compared to the contralateral hand.

Abstract
SUMMARY Nonunited fractures of the femoral shaft and distal femur are usually successfully addressed with stabilization with or without autogenous bone grafting. For the small subset of these problems that prove recalcitrant to front-line treatment, a pedicled medial femoral condyle (MFC) bone flap can provide a source of vascularized autograft with minimal donor site morbidity. The MFC has gained recent widespread adoption as a free vascularized bone transfer, and here, we present a surgical technique and retrospective analysis of patients treated with a pedicled MFC technique. This serves as a useful treatment option for these difficult problems and may be especially helpful in low resource environments or where microsurgical anastomosis is not feasible.

Abstract
PURPOSE Trigger digit release (TDR) performed in an office-based procedure room (PR) setting minimizes surgical costs compared with that performed in an operating room (OR); yet, it remains unclear whether the rates of major complications differ by setting. We hypothesized that surgical setting does not have an impact on the rate of major complications after TDR. METHODS Adult patients who underwent isolated TDR from 2006 to 2015 were identified from the MarketScan commercial database (IBM) using the provider current procedural terminology code 26055 with a concordant diagnosis on the same claim line (International Classification of Diseases, ninth revision, clinical modification 727.03). The PR cohort was defined by presence of a place-of-service code for an in-office procedure without OR or ambulatory center revenue codes, or anesthesiologist claims, on the day of the surgery. The OR cohort was defined by presence of an OR revenue code. We identified major medical complications, surgical site complications, as well as iatrogenic neurovascular and tendon complications within 90 days of the surgery using International Classification of Diseases, ninth revision, clinical modification diagnosis and/or current procedural terminology codes. Multivariable logistic regression was used to compare the risk of complications between the PR and OR groups while controlling for Elixhauser comorbidities, smoking, and demographics. RESULTS For 7,640 PR and 29,962 OR cases, the pooled rate of major medical complications was 0.99% (76/7,640) and 1.47% (440/29,962), respectively. The PR setting was associated with a significantly lower risk of major medical complications in the multivariable analysis (adjusted odds ratio 0.76; 95% confidence interval 0.60-0.98). The pooled rate of surgical site complications was 0.67% (51/7,640) and 0.88% (265/29,962) for the PR and OR cases, respectively, with no difference between the surgical settings in the multivariable analysis (adjusted odds ratio 0.81; 95% confidence interval 0.60-1.10). Iatrogenic complications were infrequently observed (PR 5/7,640 [0.07%]; OR 26/29,962 [0.09%]). CONCLUSIONS Compared with performing TDR in the OR using a spectrum of commonly used anesthesia types, performing TDR in the PR using local-only anesthesia was associated with a comparably low risk of major medical complications, surgical complications, and iatrogenic complications.

Abstract
PURPOSE Performing hand surgeries in the procedure room (PR) setting instead of the operating room effectively reduces surgical costs. Understanding the safety or complication rates associated with the PR is important in determining the value of its use. Our purpose was to describe the incidence of medical and surgical complications among patients undergoing minor hand surgeries in the PR. METHODS We retrospectively reviewed all adult patients who underwent an operation in the PR setting between December 2013 and May 2019 at a single tertiary academic medical center by 1 of 5 fellowship-trained orthopedic hand surgeons. Baseline patient characteristics were described. Complication rates were obtained via chart review. RESULTS For 1,404 PR surgical encounters, 1,796 procedures were performed. Mean patient age was 59 ± 15 years, 809 were female (57.6%), and average follow-up was 104 days. The most common surgeries were carpal tunnel release (39.9%), trigger finger release (35.9%), and finger mass or cyst excision (9.6%). Most surgeries were performed using a nonpneumatic wrist tourniquet (58%), whereas 42% used no tourniquet. No patient experienced a major medical complication. No procedure was aborted owing to intolerance. No patient required admission. No intraoperative surgical or medical complications occurred. Observed complications included delayed capillary refill requiring phentolamine administration after a trigger thumb release performed using epinephrine without a tourniquet (n = 1; 0.1%), complex regional pain syndrome (n = 3; 0.2%), infection requiring surgical debridement (n = 2; 0.2%), and recurrent symptoms requiring reoperation (n = 8; 0.7%). CONCLUSIONS In this cohort of patients in whom surgery was performed in a PR, there were no major intraoperative surgical or medical complications. There was a low rate of postoperative infection, development of complex regional pain syndrome, and a low need for revision surgery. These observations do not support the concern for safety as a barrier to performing minor hand surgery in the PR setting. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Background Social deprivation has been shown to affect access to health care services, and influences outcomes for a variety of physical and psychological conditions. However, the impact on patient satisfaction remains less clear. The objective of this study was to determine if social deprivation is an independent predictor of patient satisfaction, as measured by the Press Ganey® Outpatient Medical Practice Survey (PGOMPS). Methods We retrospectively reviewed unique new adult patient (≥ 18 years of age) seen at a tertiary academic hospital and rural/urban outreach hospitals/clinics between January 2014 and December 2017. Satisfaction was defined a priori as achieving a score above the 33rd percentile. The 2015 Area Deprivation Index (ADI) was used to determine social deprivation (lower score signifies less social deprivation). Univariate and multivariable binary logistic regression were used to determine the impact of ADI on PGOMPS total and provider sub-scores while controlling for variables previously shown to impact scores (wait time, patient age, sex, race, specialty type, provider type, and insurance status). Results Univariate analysis of PGOMPS total scores revealed a 4% decrease in odds of patient satisfaction per decile increase in ADI (p < 0.001). Patients within the most deprived quartile were significantly less likely to report satisfaction compared to the least deprived quartile (OR 0.79, p < 0.001). Multivariable analysis revealed that the odds of achieving satisfaction decreased 2% for each decile increase in ADI on the Total Score (p < 0.001), independent of other variables previously shown to impact scores. For PGOMPS Provider Sub-Score, univariate analysis showed that patients in the lowest ADI quartile were significantly less likely be satisfied, as compared to the least deprived quartile (OR 0.77; 95% CI 0.70–0.86; p < 0.001). A 5% decrease in a patient being satisfied was observed for each decile increase in ADI (OR 0.95; 95% CI 0.94–0.96; p < 0.001). Conclusions Social deprivation was an independent predictor of outpatient visit dissatisfaction, as measured by the Press Ganey® Outpatient Medical Practice Survey. These results necessitate consideration when developing health care delivery policies that serve to minimize inequalities between patients of differing socioeconomic groups.

Abstract
Background and/or Hypothesis Prior literature has supported similar complication rates and outcomes for humeral shaft fractures treated with open reduction internal fixation (ORIF) with a plate/screw construct versus intramedullary nailing (IMN). The purpose of this study is to determine whether surgical encounter total direct costs (SETDCs) differ between ORIF and IMN for these fractures. Methods Adult patients (≥ 18 years) treated for isolated humeral shaft fractures by ORIF or IMN between June 18, 2014 and June 17, 2019 at a single tertiary academic center were available for inclusion. SETDCs for ORIF and IMN groups, obtained through our institution's information technology value tool, were adjusted to 2019 US dollars and converted to relative costs per institutional policy. SETDCs for ORIF and IMN were compared using the Wilcoxon rank-sum test. Results Demographic factors did not differ between ORIF and IMN cohorts with the exception of age (mean of 18.6 years older for IMN; P < .001) and American Society of Anesthesiologist class (higher for IMN; P = .029). Substantial cost variation was observed among the 39 included ORIF and 21 IMN cases. Costs pertaining to operating room utilization (P = .77), implants (P = .64), and the recovery room (P = .27) were similar for ORIF and IMN, whereas supply costs were significantly greater for IMN with a median (interquartile range) of 0.21 (0.17 ∼ 0.28), more than twice the supply costs of ORIF (0.09 [0.05 ∼ 0.13], P < .001). The SETDC of IMN was significantly greater than that of ORIF (median [interquartile range]:1.00 [0.9 to 1.13] vs. 0.83 [0.71∼1.05], respectively; P = .047). Discussion and/or Conclusion Our study found that the SETDC for humeral shaft fracture fixation was greater for IMN than for ORIF, although patient cohorts differed significantly with respect to age and the American Society of Anesthesiologist class. Surgeons should take these findings into consideration when consenting patients with humeral shaft fractures for the appropriate fixation type.

Abstract
ABSTRACT Measuring patient satisfaction scores and interpreting factors that impact their variation is of importance as scores influence various aspects of health care administration. Our objective was to evaluate if Press Ganey scores differ between medical specialties.New patient visits between January 2014 and December 2016 at a single tertiary academic center were included in this study. Press Ganey scores were compared between specialties using a multivariable logistic mixed effects model. Secondary outcomes included a comparison between surgical versus non-surgical specialties, and pediatric versus adult specialties. Due to the survey's high ceiling effect, satisfaction was defined as a perfect total score.Forty four thousand four hundred ninety six patients met inclusion criteria. Compared to internal medicine, plastic surgery, general surgery, dermatology, and family medicine were more likely to achieve a perfect overall score, as, with odds ratios of 1.46 (P = .02), 1.29 (P = .002), 1.22 (P = .004), and 1.16 (P = .02) respectively. Orthopaedics, pediatric medicine, pediatric neurology, neurology, and pain management were less likely to achieve satisfaction with odds ratios of 0.85 (P = .047), 0.71 (P < .001), 0.63 (P = .005), 0.57 (P < .001), and 0.51 (P = .006), respectively. Compared to pediatric specialties, adult specialties were more likely to achieve satisfaction (OR 1.73; P < .001). There were no significant differences between surgical versus non-surgical specialties.Press Ganey scores systematically differ between specialties within the studied institution. These differences should be considered by healthcare systems that use patient satisfaction data to modify provider reimbursement.

Abstract
PURPOSE Our primary purpose was to evaluate the reliability of telephone administration of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Computer Adaptive Test (CAT) version 2.0 in a hand and upper extremity population, and secondarily to make comparisons with the abbreviated version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH). METHODS Patients more than 1 year out from hand surgeries performed at a single tertiary institution were enrolled. Half of the patients completed telephone PROMIS UE CAT and QuickDASH surveys first, followed by computer-based surveys 1 to 10 days later, and the other half completed them in the reverse order. Telephone surveys were readministered 2 to 6 weeks later to evaluate test-retest reliability. Concordance correlation coefficients (CCCs) were used to assess agreement between telephone and computer-based scores, and intraclass correlation coefficients (ICCs) were used to assess test-retest reliability. The proportion of patients with discrepancies in follow-up scores that exceeded estimates of the minimal clinically important difference (MCID) was evaluated. RESULTS For the 89 enrolled patients, the PROMIS UE CAT CCC was 0.82 (83% confidence interval [83% CI], 0.77-0.86; good), which was significantly lower than 0.92 (83% CI, 0.89-0.94; good to excellent) for the QuickDASH. The PROMIS UE CAT ICC did not differ significantly from the QuickDASH (0.85 and 0.91, respectively). Differences in telephone versus computer scores exceeded 5 points (MCID estimate) for the PROMIS UE CAT in 34% of patients versus 5% of patients exceeding 14 points (MCID estimate) for the QuickDASH. CONCLUSIONS Significantly better reliability was observed for the QuickDASH than the PROMIS UE CAT when comparing telephone with computer-based score acquisition. Over one-third of patients demonstrated a clinically relevant difference in scores between the telephone and the computer-administered tests. We conclude that the PROMIS UE CAT should only be administered through computer-based methods. CLINICAL RELEVANCE These findings suggest that differences in collection methods for the PROMIS UE CAT may systematically affect the scores obtained, which may erroneously influence the interpretation of postoperative scores for hand surgery patients.

Abstract
BACKGROUND Athletes demonstrate high levels of physical function, leading to difficulties in patient-reported outcome scoring and interpretation. In particular, the ability of patient-reported outcome (PRO) instruments to adequately discriminate between high levels of upper extremity function-that is, the ceiling effect-is limited. This study evaluated performance characteristics of the shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) survey and Patient-Reported Outcomes Measurement Information System (PROMIS) metrics in a population of Division 1 intercollegiate athletes, with specific attention to ceiling effects. METHODS At a single institution, Division I intercollegiate athletes cleared for full participation in the 2018-2019 season were eligible. The following PROs were collected prospectively via tablet computer: PROMIS upper extremity (UE) computer adaptive test (CAT), PROMIS physical function (PF) CAT, QuickDASH, and QuickDASH Sports/Performing Arts Module. Descriptive statistics, and ceiling and floor effects, were calculated. The proportion of athletes with maximal scores on each PRO were compared to normative values using the 1-sample Wilcoxon signed rank test. RESULTS A total of 268 participants were included; the mean age was 19.9 ± 1.5 years, 49% were female, and 61% were overhead athletes. Large ceiling effects were observed for the UE CAT (46%), QuickDASH (58%), and QuickDASH Sports Module (82%). The PF CAT demonstrated a relatively low ceiling effect of 6.7%. Athlete scores were all significantly better than published age-matched values from a normative population for all instruments, with the exception of no difference on the QuickDASH for males. DISCUSSION AND/OR CONCLUSION The PROMIS UE CAT and QuickDash instruments are limited in their ability to assess and discriminate upper extremity function in highly functioning individuals such as Division I athletes. The PROMIS PF CAT, a measure of general physical function, did not suffer from a large ceiling effect.

Abstract
Purpose Carpal tunnel release (CTR) surgical costs are minimized when performed in the procedure room (PR) setting, compared with the operating room. However, it remains unclear whether outcomes differ between surgical settings. Our purpose was to compare outcomes at 1 year or greater follow-up after open CTR between patients treated in PR versus operating room settings using the Boston Carpal Tunnel Questionnaire (BCTQ). Methods A change in clinical care protocols at our institution occurred in 2014. Before this, all CTRs were performed in the operating room; thereafter, these were transitioned to the PR. Adult patients who underwent isolated unilateral or bilateral open CTR in either surgical setting were considered for inclusion, in which procedures were conducted between January 2014 and October 2018 for the PR group and January 2009 and March 2014 for the operating room group. The Functional Status Scale (FSS) and the Symptom Severity Scale (SSS) components of the BCTQ were collected for all eligible patients at a minimum of 1 year after surgery. We used univariate and multivariable linear regression to determine whether postoperative BCTQ scores were equivalent between PR and operating room groups within a threshold of one-fourth of the lowest estimates of the minimal clinically important difference. Results No differences in demographics, comorbidities, or insurance type were observed between the 104 PR and 112 operating room patients. Survey response rate was 25% and 25% for the PR and operating room patients, respectively. At a mean follow-up of 3 ± 1 years, FSS and SSS scores were equivalent between PR and operating room groups on bivariate analysis. The multivariable equivalence test also demonstrated equivalent FSS and SSS scores between PR and operating room groups within a one-fourth minimal clinically important difference threshold while controlling for age, sex, presence of diabetes or thyroid disease, unilateral versus bilateral CTR, and surgeon. Conclusions Clinical outcomes did not differ between PR and operating room settings after open CTR. Type of study/level of evidence: Therapeutic III.

Abstract
PURPOSE The relationship between biopsychosocial factors and patient-reported function is less clear in pediatric than in adult hand surgery patients. Our primary hypothesis was that pain interference (PI) and peer relationships (PR) would demonstrate association with upper extremity function. Secondarily, we hypothesized that the magnitude of this effect would increase with age. METHODS Patients aged 5 to 17 years presenting to a tertiary academic clinic between October 2017 and January 2019 were included. The parent/guardian was administered the following instruments after indicating they, rather than the patient, were answering the questions on a tablet computer: Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Parent Proxy (PP) Computer Adaptive Test (CAT) v2.0, PROMIS PI PP CAT v2.0, and the PROMIS PR PP CAT v2.0. Ceiling/floor effects and Spearman correlations were calculated. Multivariable Tobit modeling was performed to determine whether biopsychosocial factors and upper extremity function were associated. Multivariable regression coefficients were compared between age cohorts using a separate multivariable model to evaluate the interaction between age and other predictors. RESULTS Of 139 included participants, the mean age was 11.7 ± 3.7 years and 50% were female. For patients 11 years of age or younger, UE was weakly correlated with PI (coefficient, -0.34; 95% confidence interval, -0.56 to -0.08) and was not correlated with PR. For patients older than 11 years, UE had moderate correlation with PI (coefficient, -0.60; 95% confidence interval, -0.72 to -0.45) and was not correlated with PR. Multivariable analysis demonstrated a significant negative association between PI and UE, with a significantly larger magnitude of effect for patients older than 11 years of age. CONCLUSIONS The biopsychosocial model applies to pediatric hand surgery patients. The association between greater pain interference and worse patient-reported upper extremity function, as assessed using parent proxy instruments, was significantly stronger for patients older than 11 years than those 11 years old or younger. CLINICAL RELEVANCE This study suggests that the biopsychosocial model applies to pediatric hand patients.

Abstract
Background First extensor compartment release is a common surgical procedure that represents a financial burden to the health care system. Questions/Purposes Study questions included (1) whether surgical encounter costs differ based upon surgical setting (operating room [OR] vs. procedure room [PR]) or (2) based upon anesthesia choice (local only, Bier's block [BB], monitored anesthesia care [MAC], or general [GA]) for De Quervain release (DQR). Patients and Methods Consecutive adult patients undergoing isolated unilateral DQR at a single academic medical center were identified retrospectively by Current Procedural Terminology code (25000). Using our institution's information technology value tools, we calculated total direct costs for each surgical encounter. Costs were adjusted to January 2016 dollars using the Consumer Price Index, normalized using each participant's surgical encounter cost divided by the median cost in the PR group, then compared across each group using Kruskal-Wallis and Nemenyi's post hoc pair-wise tests. Multivariable gamma regression analysis with a log link was performed to identify factors associated with surgical costs. QuickDASH (disabilities of the arm, shoulder, and the hand) scores were compared using a t -test at final follow-up. Results Among 58 included patients, 29% (17/58) were treated in the PR and 71% (41/58) in the OR. Compared with local only in the PR, all other groups were significantly more costly. Multivariable gamma regression indicated that use of OR/BB, OR/MAC, or OR/GA independently led to 211, 222, and 357% greater surgical costs as compared with the PR with local only while controlling for provider and patient age. Furthermore, QuickDASH scores were similar between PR and OR groups at final follow-up. Conclusion Performing DQR in the PR setting under local only anesthesia yields greater value than the OR, as patient-reported outcomes are similar despite significantly lower surgical costs. Level of Evidence This is a Level III, cost analysis study.

Abstract
BACKGROUND It remains unclear whether volar locked plating (VLP) yields a better functional outcome than closed reduction and casting (CRC) for elderly patients with an acute, displaced distal radial fracture. Our purpose was to conduct a systematic review and meta-analysis of randomized controlled trials comparing outcomes of VLP and CRC for elderly patients (age, ≥60 years). METHODS Multiple databases, including MEDLINE, were searched for randomized controlled trials evaluating outcomes following distal radial fracture treatment. Raw data were obtained for studies that included patients of all ages, and the elderly subgroup was included for analysis. The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) score at ≥1 year of follow-up. Secondary outcomes included the 3-month DASH score, range of motion, final radiographic alignment, and complications. Effect sizes for the comparison of each outcome between groups were pooled across studies using random-effects models with the inverse variance weighting method. Changes in DASH score were compared with a minimal clinically important difference (MCID) estimate of 10 to assess clinical relevance. RESULTS Of 2,152 screened articles, 6 were included. Demographics were similar for the 274 VLP and 287 CRC patients. DASH scores were significantly better following VLP than CRC at the time of final follow-up (12 to 24 months postoperatively; score difference, -5.9; 95% confidence interval [CI], -8.7 to -3.1) and at 3 months (-8.9; 95% CI, -13.0 to -4.8). VLP yielded significantly better palmar tilt, radial inclination, and supination, with no differences in ulnar variance, flexion-extension, pronation, or total complication rates. CONCLUSIONS Functional outcome was significantly better following VLP than CRC 3 months into the treatment of acute, displaced distal radial fractures in an elderly population and up to 2 years after injury. However, the observed differences in the final DASH score did not exceed published estimates of the MCID, suggesting that clinical outcomes are similar for both treatment options.

Abstract
BACKGROUND For stage-II scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) patterns of wrist arthritis, the optimal method of surgical treatment remains unclear. Previous literature has demonstrated similar clinical outcomes between proximal row carpectomy (PRC) and 4-corner arthrodesis (FCA), making the risk of reoperation a focus of particular interest. In the present study, the primary null hypothesis was that there would be no difference in the rate of conversion to total wrist arthrodesis between PRC and FCA. Additionally, we hypothesized that the rate of secondary surgical procedures would be similar between the 2 procedures. METHODS The national Veterans Health Administration Corporate Data Warehouse was utilized to identify 2,449 patients who underwent either PRC or FCA between 1992 and 2016. With use of operative reports to identify the arthritis pattern, only cases of stage-II SLAC/SNAC were included. All complications and subsequent surgical procedures were confirmed by manual chart review. Propensity score analyses with matching weights were utilized to balance the PRC and FCA cohorts. The rates of conversion to wrist arthrodesis and secondary surgical procedures were calculated. RESULTS Of the 1,168 patients with stage-II SLAC/SNAC arthritis, 933 wrists underwent PRC and 257 wrists underwent FCA. Ten-year survival free of total wrist arthrodesis in the matching PRC (251 procedures) and FCA (251 procedures) cohorts was 94.3% (95% confidence interval [CI], 92.3% to 96.3%) and 94.1% (95% CI, 90.8% to 97.4%), respectively. Survival free of a secondary surgical procedure other than wrist arthrodesis was 99.7% (95% CI, 99.3% to 100.0%) for PRC and 83.5% (95% CI, 78.2% to 88.8%) for FCA. CONCLUSIONS PRC and FCA demonstrated similarly low rates of conversion to total wrist arthrodesis. In contrast, the rate of secondary surgical procedures following FCA was significantly higher compared with PRC. Given the historically similar clinical outcomes between PRC and FCA, the results of the present study show that PRC may be a preferable treatment for stage-II SLAC/SNAC wrist arthritis.

Abstract
Background: The optimal surgical treatment for scapholunate advanced collapse (SLAC) and
scaphoid nonunion advanced collapse (SNAC) remains unclear. To inform
clinical decision-makers, we conducted a cost-effectiveness analysis
comparing proximal row carpectomy (PRC) and four-corner arthrodesis
(FCA). Methods: A Markov microsimulation model was used to compare clinical outcomes, costs,
and health utilities between PRC and FCA. The model used a 10-year time
horizon and a 1-month cycle length, and it was evaluated from the societal
perspective. Utilities and clinical parameters including transition
probabilities for debridement for infection, removal of implants, conversion
to total wrist arthrodesis, revision FCA, and revision total wrist
arthrodesis were obtained from published literature. Timing of complications
was estimated from the literature. Direct medical costs were derived from
Medicare ambulatory surgical cost data, and indirect costs for missed work
due to surgical procedures and complications were included. The
effectiveness outcome was quality-adjusted life years (QALYs). Probabilistic
sensitivity analysis and 1-way threshold analysis for utilities were
performed. Results: In the base-case model, PRC dominated FCA (i.e., PRC had lower cost and
greater effectiveness). The mean (and standard deviation) for the total cost
and QALYs per patient were $30,970 ± $5,931 and 8.24 ± 1.28,
respectively, for PRC and $44,526 ± $11,205 and 8.23 ± 1.26,
respectively, for FCA. In the probabilistic sensitivity analysis, PRC
dominated FCA in 57% of the 1 million iterations. The cost-effectiveness
acceptability curve indicated that PRC is the most cost-effective strategy
regardless of the willingness-to-pay threshold up to $100,000/QALY. Conclusions: PRC dominated FCA in the base-case analysis and in the probabilistic
sensitivity analysis. These results suggest that PRC is the optimal strategy
for Stage-I or II SLAC and for SNAC in patients ≥55 years of age. Level of Evidence: Economic Level IV. See Instructions for Authors for a

Abstract
PURPOSE The minimal clinically important difference (MCID) is used in research and clinical settings as a benchmark to gauge improvement following treatment. The purpose of this study was to provide anchor-based MCID estimates for Patient-Reported Outcomes Measurement Information System (PROMIS) and legacy instruments in a nonshoulder hand and upper extremity population. METHODS Adult patients (≥18 years) seeking care at a tertiary academic outpatient hand surgery clinic completed patient-reported outcome measures on tablet computers between January 2015 and August 2017. Data were collected at baseline and at 6 ± 2 weeks of follow-up. The PROMIS Upper Extremity (UE), Physical Function (PF), and Pain Interference (PI) Computer Adaptive Test (CAT) instruments were administered, along with the shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH). A mean change anchor-based method was used to estimate MCIDs by comparing scores between anchor groups reporting no change versus slightly improved in terms of function and pain. RESULTS Scores for each instrument significantly improved over the study period. With significant differences in scores between groups reporting no change and slightly improved function, anchor-based MCID estimates were calculated as follows: 2.1 for the PROMIS UE CAT, 1.7 for the PROMIS PF CAT, and 6.8 for the QuickDASH. There was no significant difference in PROMIS PI CAT scores between anchor groups when queried for level of pain improvement, precluding estimation of an anchor-based MCID. CONCLUSIONS We have provided anchor-based MCID estimates for the PROMIS UE CAT, PROMIS PF CAT, and the QuickDASH for a general nonshoulder hand and upper extremity population. These values may be useful in future research for informing power calculations and when interpreting whether the magnitude of change on these instruments is clinically significant at a population level. CLINICAL RELEVANCE This study provides clinicians with a reference for values that may reflect clinically meaningful changes in scores for patient-reported outcome instruments commonly utilized in the current hand surgery literature.

Abstract
INTRODUCTION The Press Ganey® Outpatient Medical Practice Survey (PGOMPS) is composed of 10 provider-specific and 15 non-provider-specific questions. Some healthcare systems link PGOMS overall scores to physician reimbursements. The aim of this study was to determine the frequency of patient satisfaction across individual PGOMPS question, the null hypothesis being that there was no variability between the frequency of satisfaction and similar questions. METHODS We reviewed all new patient orthopedic PGOMPS scores between January 2014 and December 2017. Due to the large ceiling effect, satisfaction was defined as a perfect total score. The frequency of perfect scores for each question was calculated. RESULTS Five thousand one hundred sixty-three patients met the inclusion criteria. Two thousand two hundred sixty-six (43.89%) provider-specific questions received perfect satisfaction versus 986 (19.10%) with perfect satisfaction for non-provider-specific questions (p < 0.001). The five questions most likely to receive perfect satisfaction were MD friendliness/courtesy (80.36), MD spoke using clear language (80.35%), likelihood to recommend practice (79.11%), likelihood to recommend MD (78.8%), and MD confidence (78.74%). The five least likely were convenience of office hours (60.44%), ease of getting on phone (59.72%), ability to get desired appointment (59.50%), wait time (54.63%), and information about delays (53.80%). CONCLUSIONS Our results suggest that the majority of orthopedic patients are satisfied with their provider, demonstrating that room for improvement is limited with provider-specific areas. Leaders of health care teams should consider these results when seeking to improve patient satisfaction scores and determining how and if scores should be linked to reimbursements.

Abstract
PURPOSE In light of recently-proposed quality measures for carpal tunnel release (CTR), elucidating the minimal clinically important difference (MCID) for selected outcome measures will be important when interpreting treatment responses. Our purpose was to estimate the MCID of the Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the short Disabilities of the Arm, Shoulder, and Hand (QuickDASH) following CTR. METHODS Adult patients undergoing isolated unilateral CTR between July 2014 and October 2016 were identified. Outcomes included the PROMIS Upper Extremity (UE) Computer Adaptive Test (CAT), Physical Function (PF) CAT, QuickDASH, and Pain Interference (PI) CAT. For inclusion, pretreatment baseline (within 60 days of surgery) and postoperative (6-90 days) UE or PF CAT scores were required, as well as a response on a 5-point Likert scale to the question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" The MCID was calculated using SD and minimum detectable change (MDC) distribution methods. RESULTS In response to the Likert scale question, 88.6% of patients reported improvement at a mean of 14.8 days after surgery. The infrequency of patients reporting no change (5 of 44; 11.4%) precluded calculation of a statistically sound anchor-based MCID value. The MCID values, as calculated using the one-half SD method, were 3.6, 4.6, 10.4, and 3.4 for the UE CAT, PF CAT, QuickDASH, and PI CAT, respectively. CONCLUSIONS We have calculated MCID values for the UE CAT, PF CAT, QuickDASH, and PI CAT for patients undergoing CTR. Although the small number of patients reporting no change and minimal change after surgery precluded an anchor-based MCID calculation, we report estimates using the one-half SD method for the MCID following CTR. CLINICAL RELEVANCE These MCID estimates will be helpful when interpreting CTR clinical outcomes and for powering prospective trials.

Abstract
The Press Ganey Outpatient Medical Practice Survey is a commonly utilized questionnaire that attempts to measure satisfaction with outpatient health care. A wide variety of factors have been associated with lower satisfaction scores among orthopaedic patients, including age, sex, presence of psychological disorders, and driving distance to the point of care. The impact of clinic workflows is less clear. In this study, we hypothesized that an increased clinic wait time was an independent predictor of lower patient satisfaction as measured by the Press Ganey survey.

Abstract
We investigated whether incision type affects scar quality or outcome following trigger finger release. Our primary and secondary hypotheses were that transverse and longitudinal incision types yield similar scar quality and functional improvement. Digits undergoing trigger finger release at the participating hospitals were randomized to receive transverse or longitudinal incisions. The Patient Scar Assessment Scale, Observer Scar Assessment Scale, and the Disabilities of the Arm, Shoulder and Hand score were collected at 8 and 54 weeks postoperatively. Of 86 randomized patients, 67 patients (71%) had followed-up at 54 weeks postoperatively. We found no significant differences in above three assessments between the incisions at either time-point. Among patients receiving both incision types for multiple simultaneous trigger finger release, there were no significant differences in Patient Scar Assessment Scale or Observer Scar Assessment Scale scores. We found no significant difference in the scar quality and improvement in patient-reported disability with transverse or longitudinal incisions for trigger finger release. Level of evidence: II.

Abstract
PURPOSE To test the null hypothesis that baseline opioid use is not associated with functional or psychological impairment among new hand surgery clinic patients, as measured by Patient-Reported Outcomes Measurement Information System (PROMIS) instruments. METHODS New adult (≥ 18 years) patient visits to a tertiary academic orthopedic nonshoulder hand and upper extremity clinic between February 2014 and April 2018 were eligible. Collected outcomes include the question, "Are you currently taking narcotic pain medications?", the PROMIS Upper Extremity (UE) computerized adaptive testing (CAT), abbreviated version of the Disorders of the Arm, Shoulder, and Hand (QuickDASH), PROMIS Physical Function (PF) CAT, PROMIS Pain Interference (PI) CAT, PROMIS Depression CAT, and PROMIS Anxiety CAT. Patients responding to the opioid question, plus the UE CAT or QuickDASH, were included. Bivariate and multivariable logistic regression modelling were used to assess factors associated with baseline scores. RESULTS Of 5997 included patients, 1,046 (17.4%) reported baseline opioid use. Patients in the opioid group demonstrated significantly worse scores on all patient-reported outcomes, and a significantly greater proportion of patients with PROMIS Depression CAT scores exceeding 60 (associated with a clinical diagnosis of depression; 29.5% vs 15.5%). Lower functional scores were observed in the opioid group after controlling for age, sex, other activity-limiting comorbidities, and either depression (UE CAT -7.0; QuickDASH +18.1; and PF CAT -6.6 points), anxiety (UE CAT -6.3; QuickDASH +16.4; PF CAT -6.3), or PI (UE CAT -3.7; QuickDASH +9.5; and PF CAT -4.2 points). Pain interference was greater among opiate users when controlling for age, sex, other activity-limiting comorbidities, and baseline function or psychological status: PI was 2.5, 5.0, or 4.3 points greater when controlling for the PROMIS UE CAT, Depression CAT, or Anxiety CAT. CONCLUSIONS New patients presenting to a hand surgery clinic who endorse use of opioid medications at baseline report significantly decreased physical function, increased psychological burden, and greater levels of pain interference than nonusers.

Abstract
OBJECTIVES To evaluate the utility of follow-up radiographs in patients with isolated partial articular radial head fractures (OTA/AO 2R1B1 or 2R1B3). DESIGN Retrospective cohort study. SETTING Academic Level 1 Trauma Center. PATIENTS Adult patients (≥18 years) with isolated partial articular radial head fractures indicated for initial nonoperative treatment. INTERVENTION Analysis of elbow radiographs at initial presentation and at postinjury follow-up of 3-8 weeks. VARIABLES MEASURED Articular gap and step-off. MAIN OUTCOME MEASURE Radiographic articular displacement between initial and follow-up radiographs. RESULTS For 72 included patients, initial radiographs were obtained on average 2.6 days after injury and follow-up radiographs 33.7 days thereafter. Equivalence tests evaluating gap and step-off thresholds of <1 mm were both significant, indicating that the cohort displaced <1 mm for both parameters between initial and follow-up radiographs. No patients proceeded to surgical treatment following the repeat radiographs. CONCLUSIONS These fractures do not displace in the early postinjury period, as defined as a <1 mm of change in both intra-articular gap and step-off, as compared to initial radiographs. Routine follow-up radiographs for these injuries is a source of cost, but with limited utility in detecting interval displacement or leading to a change in management. Selective use of radiographs to evaluate specific clinical concerns may lead to cost savings. LEVEL OF EVIDENCE Diagnostic Level IV.

Abstract
PURPOSE Our purpose was to test the null hypothesis that no patient or clinic visit characteristics affect satisfaction of hand surgery outpatients, as measured by the Press Ganey Outpatient Medical Practice Survey (PGOMPS). METHODS Adult patients (≥ 18 years) evaluated by 5 fellowship-trained hand surgeons between January 2014 and December 2016 for a new patient clinic visit at a single tertiary academic medical center, were included. Prospectively collected PGOMPS data were reviewed retrospectively for each visit. Chart review was performed to collect demographic and visit characteristics data. Satisfaction was defined a priori as achieving a PGOMPS score above the 33rd percentile. Both the PGOMPS Total Score (primary outcome) and Provider Subscore (secondary outcome) were analyzed using univariate and multivariable logistic regression. RESULTS Of 748 included patients, the mean age was 51.7 ± 15.5 years, and 64% were women. Leading diagnoses included tendinitis (19%), neuropathy (19%), arthritis (16%), and fracture-dislocation (13%). Multivariable modelling of the PGOMPS Total Score revealed that older age, shorter wait times, and scheduling surgery were significantly associated with greater satisfaction. The PGOMPS Provider Sub-Score multivariable modelling revealed that older age, shorter wait times, scheduling surgery, and administering injections were significantly associated with greater satisfaction. Diagnostic category and insurance status did not affect satisfaction. CONCLUSIONS Increasing patient age, decreased wait time, and receiving an intervention (scheduling of surgery or receiving an injection) are associated with increased satisfaction among newly presenting hand surgery clinic patients as measured by the Press Ganey Outpatient Medical Practice Survey. Diagnosis and access to health care (insurance status and distance to clinic) did not influence patient satisfaction. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
PURPOSE The Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) was recently updated to version 2.0 (v2.0). We hypothesized that the PROMIS UE CAT v2.0 would exhibit improved performance characteristics compared with the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) when administered to a nonshoulder upper extremity patient population. METHODS The UE CAT v2.0, Physical Function (PF) CAT v2.0, and the QuickDASH were each prospectively administered via tablet computer to all patients presenting to a tertiary hand and upper extremity clinic between April 2017 and October 2017. Patient responses were analyzed, and the mean, range, floor and ceiling effect, and correlations between instruments were calculated. RESULTS Among 825 patients, the mean UE CAT v2.0 score was 38.3 (SD 10.7) with a range of 15 to 61 and interquartile range of 15.4. The UE CAT v2.0 had a strong correlation with the QuickDASH (r = -0.749) and the PF CAT v2.0 (r = 0.719). No patient scored between 56 and 60, indicating a gap in scoring in that range. The UE CAT v2.0 demonstrated a floor effect of 1%, a ceiling effect of 6.9%, and a high internal consistency with a Cronbach alpha of 0.99. CONCLUSIONS The PROMIS UE CAT v2.0 demonstrated improved ceiling effects, range, and a decreased gap in scoring compared with prior versions. Limitations of the PROMIS UE CAT v2.0 are still present, but updates have led to an incremental improvement over prior versions, demonstrating the ability to influence PROMIS instrument performance through upgrades. CLINICAL RELEVANCE The updated PROMIS UE CAT v2.0 still demonstrates a ceiling effect and gap in scores at the upper end of the instrument, both of which may limit discrimination between different levels of upper extremity function for high-functioning patients.

Abstract
BACKGROUND In situ decompression, subcutaneous transposition, and submuscular transposition for cubital tunnel syndrome have historically yielded similar outcomes. The authors' null hypothesis is that no differences exist in surgical encounter total direct costs for in situ decompression, subcutaneous transposition, and submuscular transposition. METHODS Adult patients treated surgically for cubital tunnel syndrome by four fellowship-trained hand surgeons between August of 2011 and December of 2016 were identified by CPT code (64718) at their tertiary academic institution. Patients with prior elbow surgery or fracture/dislocation and those undergoing revision or additional simultaneous procedures were excluded. Using their institution's information technology value tools, the authors extracted prospectively collected surgical encounter total direct costs data for each surgical encounter. Costs were compared between groups and modeled using univariate and multivariable gamma regression. RESULTS In situ decompression, subcutaneous transposition, and submuscular transposition were performed on 45, 62, and 14 unique surgical encounters, respectively, with mean surgical times of 28.0, 46.5, and 50.0 minutes, respectively. Costs differed significantly between surgical methods. Surgical method and provider significantly affected surgical encounter total direct costs in the univariate model. Multivariable modeling demonstrated that subcutaneous transposition was 1.18-fold more costly than in situ decompression and submuscular transposition was 1.55-fold more costly than in situ decompression while controlling for age, sex, and provider. CONCLUSIONS Surgical costs differed significantly between in situ decompression, subcutaneous transposition, and submuscular transposition. Given historically similar outcomes reported for these techniques, cost differences should be considered in addition to clinical factors to inform surgical decision-making for cubital tunnel syndrome patients.

Abstract
Background Proximal row carpectomy (PRC) and four-corner arthrodesis (FCA) are common treatments for stage II scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) wrists, with similar functional and patient-reported outcomes reported in the peer-reviewed literature. Questions Study questions included (1) whether surgical encounter total direct costs (SETDCs) differ between PRC and FCA, and (2) whether SETDC differs by method of fixation for FCA. Patients and Methods Consecutive adult patients (≥ 18 years) undergoing PRC and FCA between July 2011 and May 2017 at a single tertiary care academic institution were identified. Patients undergoing additional simultaneous procedures were excluded. Using our institution's information technology value tools, we extracted prospectively collected cost data for each surgical encounter. SETDCs were compared between PRC and FCA, and between FCA subgroups (screws, plating, or staples). Results Of 42 included patients, mean age was similar between the 23 PRC and 19 FCA patients (51.2 vs. 54.5 years, respectively). SETDCs were significantly greater for FCA than PRC by 425%. FCA involved significantly greater facility costs (2.3-fold), supply costs (10-fold), and operative time (121 vs. 57 minutes). Implant costs were absent for PRC, which were responsible for 55% of the SETDC for FCA. Compared with compression screws, plating and staple fixation were significantly more costly (70% and 240% greater, respectively). Conclusion SETDCs were 425% greater for FCA than PRC. Implant costs for FCA alone were 130% greater than the entire surgical encounter for PRC. For FCA, SETDC varied depending on the method of fixation. Level of Evidence This is a level III, cost analysis study.

Abstract
BACKGROUND A complete understanding of the variables that influence patient satisfaction has yet to be reached. The purpose of this study was to determine whether patient-reported physical function, pain, and/or anxiety are associated with patient satisfaction in a hand and upper-extremity outpatient setting. METHODS This is a cohort study of 1,160 adult patients presenting to an upper-extremity (non-shoulder) clinic from January 1, 2014, to December 31, 2016, who completed functional patient-reported outcome measures (PROMIS [Patient-Reported Outcomes Measurement Information System] Physical Function, PROMIS Upper Extremity, and abbreviated Disabilities of the Arm, Shoulder and Hand scale [QuickDASH]) and psychological patient-reported outcome measures (PROMIS Anxiety and PROMIS Pain Interference) immediately prior to their physician encounter. After the clinic visit, included patients filled out the Press Ganey Medical Practice satisfaction survey online. Logistic regression models were used to predict overall patient satisfaction and satisfaction with the care provider among all, new, and return clinic visit types from the patient-reported functional and psychological measures, controlling for age and provider. RESULTS Among all visit types, there was a significant negative association of both pain and anxiety with patient satisfaction, whereby a 10-point increase in PROMIS Pain Interference (higher self-reported pain symptomatology) was associated with a 17% decrease in the odds of overall satisfaction (odds ratio [OR], 0.83 [95% confidence interval (CI), 0.71 to 0.98]; p = 0.03), and a 10-point increase in PROMIS Anxiety (higher self-reported anxiety) was associated with a 16% decrease in the odds of satisfaction with the care provider (OR, 0.84 [95% CI, 0.72 to 0.97]; p = 0.02). A significant positive association was found between higher levels of self-reported physical function and new-patient satisfaction with their care provider (OR, 1.22 [95% CI, 1.02 to 1.47]; p = 0.03). Among return patient visits, there was a negative association with overall patient satisfaction between both pain interference (OR, 0.76 [95% CI, 0.58 to 0.98]; p = 0.04) and anxiety (OR, 0.69 [95% CI, 0.53 to 0.89]; p < 0.01). CONCLUSIONS In hand and upper-extremity (non-shoulder) clinic visits, pre-encounter levels of patient-reported physical function, anxiety, and pain were significantly associated with patient satisfaction with the care provided. As the U.S. health-care system increasingly utilizes satisfaction scores in payment models and in quality assessment, these associations may influence how such metrics are interpreted and are utilized.

Abstract
PURPOSE Carpal tunnel release (CTR) is a common surgical procedure, representing a financial burden to the health care system. The purpose of this study was to test whether the choice of CTR technique (open carpal tunnel release [OCTR] vs endoscopic carpal tunnel release [ECTR]), surgical setting (operating room vs procedure room [PR]), and anesthetic type (local, monitored anesthesia care [MAC], Bier block, general) affected costs or payments. METHODS Consecutive adult patients undergoing isolated unilateral CTR between July 2014, and October 2017, at a single academic medical center were identified. Patients undergoing ECTR converted to OCTR, revision surgery, or additional procedures were excluded. Using our institution's information technology value tools, we calculated total direct costs (TDCs), total combined payment (TCP), hospital payment, surgeon payment, and anesthesia payment for each surgical encounter. Cost data were normalized using each participant's surgical encounter cost divided by the average cost in the data set and compared across 8 groups (defined by surgery type, operation location, and anesthesia type). RESULTS Of 479 included patients, the mean age was 55.3 ± 16.1 years, and 68% were female. Payer mix included commercial (45%), Medicare (37%), Medicaid (13%), workers' compensation (2%), self-pay (1%), and other (3%) insurance types. The TDC and TCP both differed significantly between each CTR group, and OCTR in the PR under local anesthesia was the lowest. The OCTR/local/operating room, OCTR/MAC/operating room, and ECTR/operating room, were associated with 6.3-fold, 11.0-fold, and 12.4-16.6-fold greater TDC than OCTR/local/PR, respectively. CONCLUSIONS Performing OCTR under local anesthetic in the PR setting significantly minimizes direct surgical encounter costs relative to other surgical methods (ECTR), anesthetic methods (Bier block, MAC, general), and surgical settings (operating room). CLINICAL RELEVANCE This study identifies modifiable factors that may lead to cost reductions for CTR surgery.

Abstract
BACKGROUND The purpose of this study was to evaluate the hypothesis that an increased duration of immobilization following trapeziectomy with ligament reconstruction and tendon interposition (LRTI) leads to improved patient-reported outcomes compared with an early mobilization protocol. METHODS At 2 institutions, we prospectively randomized 223 patients (238 thumbs) undergoing LRTI to receive 1 of 2 postoperative rehabilitation protocols. The immobilization protocol consisted of use of a postoperative forearm-based thumb-spica splint for 7 days followed by a forearm-based thumb-spica cast for 5 weeks and then by a custom forearm-based thermoplastic thumb-spica splint for an additional 6 weeks. An active range of motion (ROM) was started 6 weeks postoperatively. The early mobilization protocol consisted of the same postoperative splint for 7 days followed by use of a forearm-based thermoplastic thumb-spica splint for 3 weeks and then by a hand-based thumb-spica splint for 4 weeks. An active ROM was started 4 weeks postoperatively. The outcome measures included the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; pinch and grip strength; 9-hole peg test (NHP); visual analog scale (VAS) for pain; VAS for patient satisfaction; and wrist and thumb ROM. These were measured preoperatively and at 6, 12, 26, 52, and 104 weeks postoperatively. Differences in continuous and categorical variables were assessed with use of Tukey multiple comparisons following 1-way analysis of variance and Fisher exact tests, respectively. RESULTS A minimum follow-up of 1 year (mean, 1.7 years) was achieved for 71% (169) of the 238 randomized thumbs (157 of the 223 patients): 74 patients (80 thumbs) treated with the immobilization protocol and 83 patients (89 thumbs) treated with the early mobilization protocol. DASH scores, VAS pain scores, VAS patient satisfaction scores, and strength all improved similarly with no significant differences between groups at any time point. Wrist and thumb ROM and NHP outcomes were significantly worse for the immobilization group at 6 weeks postoperatively, with no differences observed between groups at 12 weeks and beyond. CONCLUSIONS A conservative immobilization protocol does not improve functional outcomes, satisfaction, strength, or ROM following LRTI compared with an early mobilization protocol.

Abstract
Background Proximal row carpectomy (PRC) and four-corner arthrodesis (FCA) are common surgical procedures used to treat degenerative wrist conditions; however, complications and failures can occur. Purpose This study aimed to investigate and compare the long-term rate of secondary surgeries including conversion to total wrist arthrodesis in patients who underwent PRC or FCA. Materials and Methods A retrospective chart review of all patients who underwent PRC or FCA in the past 20 years at a tertiary referral institution and associated Veterans Affairs (VA) hospital was performed. Patient demographics, comorbidities, surgical indications, and associated complications were tabulated. Patients were contacted via phone to obtain additional follow-up information regarding any additional surgeries, 10-point visual analog scale (VAS) for pain, quick Disabilities of the Arm, Shoulder, and Hand (quickDASH) scores, hand dominance, and occupational data. Results A total of 123 wrists made up the final dataset. Sixty-two wrists treated with PRC and 61 wrists treated with FCA were reviewed at a mean follow-up of 8.2 years. We did not find a significant difference in the rate of conversion to total wrist arthrodesis between the PRC (14.5%) and FCA (19.5%, p = 0.51) cohorts. Secondary operations were significantly greater in the FCA group (34.4%) compared with the PRC group (16.1%, p = 0.02). Females were 2.6 times more likely than males to undergo secondary operations when controlling for surgical procedure and smoking status ( p = 0.04). We did not detect a significant difference in VAS pain or in quickDASH scores between the two groups ( p = 0.35, 0.48, respectively). Conclusion PRC and FCA have comparable patient reported outcomes and wrist arthrodesis conversion rates at a mean follow-up of 8.2 years. In contrast, the FCA patient group had a significantly higher rate of secondary operations, including those for nonunion, symptomatic hardware, and other implant-related issues, when combined with wrist arthrodesis conversion. Level of Evidence Level IV, therapeutic study.

Abstract
BACKGROUND This study evaluated the responsiveness of several PROMIS patient-reported outcome measures in patients with hand and upper extremity disorders and provided comparisons with the qDASH instrument. METHODS The PROMIS Upper Extremity computer adaptive test (UE CAT) v1.2, the PROMIS Physical Function (PF) CAT v1.2, the PROMIS Pain Interference (PI) CAT v1.1 and the qDASH were administered to patients presenting to an orthopaedic hand clinic during the years 2014-2016, along with anchor questions. The responsiveness of these instruments was assessed using anchor based methods. Changes in functional outcomes were evaluated by paired-sample t-test, effect size, and standardized response mean. RESULTS There were a total of 255 patients (131 females and 124 males) with an average age of 50.75 years (SD = 15.84) included in our study. Based on the change and no change scores, there were three instances (PI at 3 months, PI >3 months, and qDASH >3 months follow-ups) where scores differed between those experiencing clinically meaningful change versus no clinically meaningful change. Effect sizes for the responsiveness of all instruments were large and ranged from 0.80-1.48. All four instruments demonstrated high responsiveness, with a standardized response mean ranging from 1.05 to 1.63. CONCLUSION The PROMIS UE CAT, PF CAT, PI CAT, and qDASH are responsive to patient-reported functional change in the hand and upper extremity patient population.

Abstract
The appropriate evaluation of hand and upper extremity masses is an important aspect of the care of orthopedic patients. Although most of these masses are benign, the orthopedic surgeon must have a high index of suspicion when assessing them because early diagnosis and treatment of aggressive or malignant masses may have a great effect on patient outcomes. This article provides an overview of benign and malignant osseous and soft tissue masses that orthopedic surgeons may encounter and a detailed algorithm for evaluating these masses.

Abstract
Background The Press Ganey® Medical Practice Survey (“Press Ganey® survey”) is a patient-reported questionnaire commonly used to measure patient satisfaction with outpatient health care in the United States. Our objective was to evaluate the reliability and validity of the Press Ganey® survey in a single institution setting. Methods We analyzed surveys from 34,503 unique respondents seen by 624 providers from 47 specialties and 94 clinics at the University of Utah in 2013. The University of Utah is a health care system that provides primary through tertiary care for over 200 medical specialties. Surveys were administered online. The Press Ganey® survey consisted of 24 items organized into 6 scales: Access (4 items), Moving Through the Visit (2), Nurse Assistant (2), Care Provider (10), Personal Issues (4) and Overall Assessment (2). Missingness, ceiling and floor rates were summarized. Cronbach’s alpha was used to evaluate internal consistency reliability. Confirmatory factor analysis was used to assess convergent and discriminant validities. Results Missingness was 0.01% for the total score and ranged from 0.8 to 11.4% across items. The ceiling rate was high at 29.3% for the total score, and ranged from 55.4 to 84.1% across items. Floor rates were 0.01% for the total score, and ranged from 0.1 to 2.1% across items. Internal consistency reliability ranged from 0.79 to 0.96, and item-scale correlations ranged from 0.49 to 0.9. Confirmatory factor analysis supported convergent and discriminant validities. Conclusion The Press Ganey® survey demonstrated suitable psychometric properties for most metrics. However, the high ceiling rate can have a notable impact on quarterly percentile scores within our institution. Multi-institutional studies of the Press Ganey® survey are needed to inform administrative decision making and institution reimbursement decisions based on this survey.

Abstract
Background Measures of patient satisfaction have gained prominence in recent years as changes to the American health care system have led to the incorporation of such metrics into reimbursement models. The response rate for widely-used outpatient satisfaction metrics and variables influencing the probability of survey nonresponse remain largely unknown. Methods We reviewed all unique adult patients (16,779) who completed an outpatient encounter in the Department of Orthopaedic surgery at our academic institution from 1/1/13 to 10/24/13. Survey data was linked to each clinic visit, and patient factors including age, sex, insurance type, zip code, and orthopaedic subspecialty visited were recorded. The overall survey response rate was calculated. Logistic regression was performed, and unadjusted and adjusted odds ratios of patients’ probability of responding to the Press-Ganey survey were calculated. Results Two thousand seven hundred sixty two (16.5 %) of individuals completed a Press-Ganey patient satisfaction survey and 14017 patients did not respond. For those patients considered responders, 906 patients (32.8 %) did not complete all the survey items. Among these 906 patients, the mean number of missing items was 2.24 (Standard Deviation SD: 2.19). Age, sex, insurance type, and orthopaedic subspecialty were all found to be associated with the odds of responding to our patient satisfaction survey. Advancing age increased the odds of responding to the survey (Adjusted Odds Ratio (OR) = 3.396 for ≥65 vs. 18–29, p < 0.001). Several variables were associated with a decreased odds of survey response, and included male sex (Adjusted OR = 0.782 for Males vs. Females, p < 0.001), insurance type (Adjusted OR = 0.311 for Medicaid/Self-Pay vs. Private), and subspecialty type (Adjusted OR = 0.623 for Trauma vs. Adult Reconstruction). Conclusions The response rate to the Press-Ganey Medical Practice Survey of outpatient satisfaction is low in an orthopaedic outpatient population, and furthermore, is impacted by patient characteristics such as age, sex, insurance type, and type of orthopaedic subspecialist encountered. The findings of the present study should inform future non-response weighting procedures in this area. More research is needed to assess non-response bias—including follow-up studies of non-respondents—in order to more accurately measure of patient satisfaction.

Abstract
PURPOSE The Patient-Reported Outcomes Measurement Information System Upper Extremity Computer Adaptive Test (UE CAT) has recently been made available by the National Institutes of Health to measure physical function outcomes in the upper extremity. We hypothesized that the UE CAT would psychometrically outperform the Disabilities of the Arm, Shoulder, and Hand (DASH) and the Patient-Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (PF CAT) in a hand patient population. METHODS The UE CAT, PF CAT, and DASH were each electronically administered to all adult patients who presented to a tertiary hand and upper extremity (nonshoulder) orthopedic clinic. Patient responses were retrospectively studied to determine the validity, reliability, and floor/ceiling effects of all 3 instruments using the Rasch Partial Credit Model. Responder burden and Pearson correlations were calculated for each instrument. RESULTS A total of 379 patients completed the UE CAT, PF CAT, and the DASH. On average, 6 UE CAT, 9 PF CAT, and 30 DASH questions were administered to each patient. All 3 instruments were each highly correlated with each other. Floor effects were low and similar between all instruments; however, ceiling effects were higher in the UE CAT (10.82%) than in the PF CAT (1.32%) or DASH (5.28%). High person reliability (PR) and item reliability (IR) were found for all 3 metrics: UE CAT (α = 0.99; PR = 0.91; IR = 0.94); PF CAT (α = 0.95; PR = 0.89; IR = 0.96); and DASH (α = 0.97; PR = 0.95; IR = 0.99). The UE CAT questions had the best item-fit: only 1 of 15 UE CAT items had poor fit in contrast to 4 of 30 DASH items and 7 of 33 PF CAT items. CONCLUSIONS The psychometric properties of the UE CAT compare favorably with the PF CAT and the DASH in nonshoulder upper extremity patients. The relatively large ceiling effect found in the UE CAT could be improved with item bank expansion to include items at the upper end of function. CLINICAL RELEVANCE The UE CAT is a useful patient-reported outcome measure that merits further investigation.

Abstract
BACKGROUND Increasingly, patient satisfaction surveys are being utilized to evaluate hospital and physician performance. Despite this, little is known about factors associated with patient satisfaction. The objective of this study was to determine whether selected non-modifiable patient characteristics are associated with outpatient satisfaction scores. METHODS We reviewed patient satisfaction scores from 12,177 outpatient clinical encounters at an academic orthopaedic outpatient clinic between December 2010 and October 2013. Any adult patient who completed at least one patient satisfaction survey at any point during the study period was included in this study. Factors including age, sex, employment status, type of health insurance, zip code, and orthopaedic subspecialty were recorded. Patients were divided into more satisfied and less satisfied groups, and generalized estimating equation logistic regression analysis was performed to identify factors predictive of lower patient satisfaction. RESULTS Age was found to be strongly associated with patient satisfaction, with younger patients reporting less satisfaction; the adjusted odds ratio for the patient age of eighteen to twenty-nine years compared with the patient age of eighty years or older was 2.78 (95% confidence interval, 1.74 to 3.82) (p < 0.001). This relationship was maintained in a predictive model across all age groups, both sexes, all travel distances, and all orthopaedic subspecialties. Travel distance was also associated with patient satisfaction, with patients who live closer reporting less satisfaction compared with patients who live farther away; the adjusted odds ratio for a distance of less than fifty miles compared with a distance of fifty miles or more was 1.18 (95% confidence interval, 1.03 to 1.33) (p = 0.016). CONCLUSIONS The finding that non-modifiable patient factors such as age and geographic location affect patient satisfaction challenges the utility of comparing patient satisfaction between populations that differ significantly with regard to such characteristics. CLINICAL RELEVANCE A more complete knowledge of the factors that influence patient satisfaction may enable better insight into the interpretation of current patient satisfaction metrics and may allow physicians and hospitals to improve their delivery of care.

Abstract
PURPOSE To assess the distance between the posterior interosseous nerve (PIN) and a distally and ulnarly directed guide pin for placement of a cortical button to reattach a distal biceps tendon. METHODS We used 10 fresh frozen cadaveric upper limbs without deformities and identified the PIN through a dorsal approach. We performed a single incision anterior surgical approach, detached the biceps tendon, and drilled a 1.6-mm K-wire from the base of the biceps tendon insertion in 3 different trajectories, sequentially, measuring the following drilling angles: 30° distal and 30° ulnar, 30° ulnar, and 30° distal. In each testing scenario, we measured the minimum distance in millimeters between the tip of the K-wire and the PIN using a digital caliper through the dorsal incision. RESULTS The mean and median distances from the guide wire to the PIN in each testing trajectory were each significantly different from each other, with the 30° ulnar direction leading to the greatest distance from the nerve. CONCLUSIONS We found that the 30° ulnar drilling direction resulted in a significantly greater distance from the guide wire to the PIN, in comparison with the distal-ulnar and the distal-only trajectories. CLINICAL RELEVANCE This study helps define the safe trajectory for guide wire placement in bicortical fixation of distal biceps tendon injuries.

Abstract
PURPOSE To compare stability and range of motion after hemi-hamate reconstruction versus volar plate arthroplasty in a biomechanical proximal interphalangeal (PIP) joint fracture-dislocation model. METHODS Eighteen digits from 6 cadaver hands were tested. We created defects of 40%, 60%, and 80% in the palmar base of each digit's middle phalanx, simulating an acute PIP joint fracture-dislocation. Each defect scenario was reconstructed with a hemi-hamate arthroplasty followed by a volar plate arthroplasty. A computer-controlled mechanism was used to bring each digit's PIP joint from full extension to full flexion via the digital tendons in each testing state, and in the intact state. During each testing scenario we collected PIP joint cinedata in a true lateral projection using mini-fluoroscopy. A digital radiography program was used to measure the amount of middle phalanx dorsal translation (subluxation) in full PIP joint extension. We recorded the angle at which subluxation, if present, occurred during each testing scenario. RESULTS Average dorsal displacement of the middle phalanx in relation to the proximal phalanx was 0.01 mm for the hemi-hamate reconstructed joints and -0.03 mm for the volar plate arthroplasty, compared with the intact state. Flexion contractures were noted in each of the specimens reconstructed with volar plate arthroplasty. Degree of contracture was directly correlated with defect size, averaging 20° for 40% defects, 35° for 60% defects, and 60° for 80% defects. We observed no flexion contractures in the hemi-hamate reconstructions. CONCLUSIONS Surgeons can use both hemi-hamate and volar plate arthroplasty to restore PIP joint stability following a fracture dislocation with a large middle phalanx palmar base defect. Use of volar plate arthroplasty led to an increasing flexion contracture as the middle phalanx palmar base defect increased. CLINICAL RELEVANCE Clinicians can use the information from this study to help with surgical decision-making and patient education.

Abstract
Background Radiocarpal fracture-dislocations are challenging injuries that are often associated with postoperative pain, stiffness, instability, or early arthrosis. Case Description We report a 1-year follow-up of a ligamentous radiocarpal dislocation (Dumontier group I) treated with a dorsal wrist-spanning plate and volar capsular repair with good results. Literature Review Historically, Dumontier group I injuries treated with a variety of techniques (closed reduction and casting, percutaneous pinning, and open fixation) have been associated with stiffness and loss of reduction. Clinical Relevance Distraction plating is a safe and effective technique for treating select distal radius fractures, and we suggest it has the potential to produce good outcomes when used to treat radiocarpal fracture-dislocations.

Abstract
PURPOSE To compare psychometric and responder burden characteristics between the Patient-Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (PF CAT) and the Disabilities of Arm, Shoulder, and Hand (DASH) instruments in a tertiary hand and upper extremity practice. METHODS Adult patients who presented to the clinic of 2 hand and upper extremity surgeons in a university-based tertiary care center were enrolled in this study. Participants received the DASH and PF CAT administered via tablet computer. Time to completion was recorded for both the DASH and PF CAT. We conducted statistical analyses to calculate Pearson correlation coefficients between the 2 instruments and performed a Rasch item response theory analysis to determine dimensionality, reliability, ceiling and floor effects, and item bias for each instrument. RESULTS A total of 134 patients were included. Time to completion for the DASH was 262 seconds, and for the PF CAT 57 seconds. The instruments had strong correlation (r = 0.726). The item and Pearson reliability were 0.97 and 0.94, respectively, for the DASH and 0.99 and 0.96 for the PF CAT. The DASH and PF CAT had 5% and 5% of unexplained variance, respectively. The DASH exhibited 5% of ceiling effect and 1% floor effect whereas the PF CAT had no ceiling or floor effects. CONCLUSIONS The psychometric characteristics of the Patient-Reported Outcomes Measurement Information System PF CAT instrument compared favorably with the DASH in a tertiary upper extremity practice. Patient time burden was significantly reduced with the PF CAT compared with the DASH. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
PURPOSE We performed a cadaveric biomechanical study to characterize proximal interphalangeal joint stability after an injury to different amounts of the volar articular base of the middle phalanx (intact, 20%, 40%, 60%, and 80% volar defects). METHODS Eighteen digits on 6 hands were tested through full proximal interphalangeal joint range of motion using computer-controlled flexion and extension via the digital tendons. We collected proximal interphalangeal joint kinematic cine data in a true lateral projection with mini-fluoroscopy. We measured the amount of dorsal middle phalanx translation in full proximal interphalangeal joint extension. As we cycled the joint from full flexion into extension, we recorded the angle at which subluxation occurred. RESULTS No specimens with 20% volar bony defect subluxated. All specimens in the 60% and 80% groups subluxated at an average flexion angle of 67° (range, 10° to 90°) in the 60% group and at all degrees of flexion in the 80% group. In the 40% group, 28% of specimens demonstrated subluxation at an average flexion angle of 14° (range, 4° to 40°). Mean dorsal translation of the middle phalanx in relation to the proximal phalanx at full digital extension was 0.2 mm in the 20% group, 0.8 mm in the 40% group, 3.2 mm in the 60% group, and 3.1 mm in the 80% group. CONCLUSIONS Simulated volar articular bony defects of 20% were stable, whereas those with 60% and 80% defects were unstable during digital motion. Stability in the 40% group was variable and appeared to be the threshold for stability. CLINICAL RELEVANCE Knowledge of the typical amount of middle phalanx defect and degree of proximal interphalangeal joint extension that can lead to joint instability may improve management of mechanically important proximal interphalangeal joint fracture dislocations.
