Abstract
Background Letters of recommendation (LOR) are an important component of trainee advancement and assessment. Examination of word use in LOR has demonstrated significant differences in how letter writers describe female and male applicants. Given the emphasis on increasing both gender and racial diversity among orthopaedic surgeons, we aimed to study gender and racial differences in LOR for applicants to orthopaedic surgery residencies. Methods All applications submitted to a single, academic orthopaedic residency program in 2018 were included. Self-identified gender and race were recorded. The LOR were analyzed via a text analysis software program using previously described categories of communal, agentic, grindstone, ability, and standout words. We examined the relative frequency of word use in letters for (1) male and female applicants and (2) white and underrepresented in orthopaedics (UiO) applicants, with the subgroup analysis based on whether standardized (using the American Orthopaedic Association template) or traditional (narrative) LOR were used. Results Two thousand six hundred twenty-five LOR were submitted for 730 applicants (79% men). Fifty-nine percent of applicants were self-identified as white, and 34% were self-identified as UiO. In traditional LOR, standout words (odds ratio [OR] 1.07; p = 0.01) were more likely to be used in letters for women compared with men, with no difference in any other word-use category. In standardized LOR, there were no gender-based differences in any word category. In traditional LOR, grindstone words (OR = 0.96; p = 0.02) were more likely to be used in letters for UiO than white applicants, whereas standout words (OR = 1.05; p = 0.04) were more likely to be used in letters for white candidates. In standardized LOR, there were no race-based differences in any word category use. Conclusions Small differences were found in the categories of words used to describe male and female candidates and white and UiO candidates. These differences were not present in the standardized LOR compared with traditional LOR. It is possible that the use of standardized LOR may reduce gender- and race-based bias in the narrative assessment of applicants.

Abstract
The medical device industry has long been subject to criticism for lack of price transparency and minimal regulations surrounding device approval, which have functioned as barriers to providing quality and cost-effective care. Recent health care reforms aimed at overcoming these barriers, including improving market approval regulations, increasing postmarket surveillance, and using comparative effectiveness research, have drastically changed industry practices. These reforms have also prompted increasingly cost-aware health care practices, which have encouraged new trends in medical device innovation such as frugal innovation and deinstitutionalization. This article explores the challenges faced by industry, physicians, and patients in light of these reforms.

Abstract
Illness and injury often entail lasting health and social consequences beyond the acute event. During the immediate and long-term recovery period, consequences of illness or injury can often be mitigated and addressed. As patients and their clinicians discuss care decisions, whether for initial or ongoing management of illness or injury, they must consider patients' personal goals of recovery alongside possible clinical outcomes to choose the best path forward. Understanding the recovery process and patients' and clinicians' decision making requires clarifying the concept of recovery and its significance. This article will describe how shared decision making can support the recovery process using a case example of brachial plexus injury.

Abstract
BACKGROUND Supporters of medical liability reform contend that caps on non-economic damages will decrease defensive medicine. QUESTIONS/PURPOSES We examined whether removal of caps on non-economic damages affect one type of defensive medical practice, early imaging for new-onset low back pain. PATIENTS AND METHODS Using administrative claims data, we retrospectively studied adult patients evaluated for new-onset low back pain from 2007 to 2012. We included patients from two states that had caps on non-economic damages struck down in 2010 (n = 462,604) and patients from adjacent states (n = 781,963). Using a difference-in-differences approach, we evaluated the impact of non-economic damage caps on early imaging while adjusting for physician specialty, patient characteristics, and year- and state-level fixed effects. RESULTS There was no association between non-economic damage caps and early imaging for low back pain among all providers. Removal of a non-economic damage cap was also not associated with a significant change in early imaging within the two cap-removal states. Subgroup analysis by physician specialty demonstrated significantly increased use of early imaging for low back pain by orthopedic or neurological surgeons in the first 12 months following cap removal in one state (but this difference did not persist beyond 12 months). In the other cap-removal state, early imaging increased among orthopedic and neurological surgeons more than 12 months after cap removal. CONCLUSION We found no association between caps on non-economic damages and early imaging for low back pain among all physicians. However, our subgroup analysis suggests that physician specialties may respond to non-economic damage cap policies differently.

Abstract
BACKGROUND Restoration of shoulder function is an important treatment goal in upper brachial plexus injury (UBPI). Combined dual motor nerve transfer (CDNT) of spinal accessory to suprascapular and radial to axillary nerves demonstrates good functional recovery with minimal risk of perioperative complications. OBJECTIVE To evaluate the cost-effectiveness of CDNT vs alternative operative and nonoperative treatments for UBPI. METHODS A decision model was constructed to evaluate costs ($, third-party payer) and effectiveness (quality-adjusted life years [QALYs]) of CDNT compared to glenohumeral arthrodesis (GA), conservative management, and nontreatment strategies. Estimates for branch probabilities, costs, and QALYs were derived from published studies. Incremental cost-effectiveness ratios (ICER, $/QALY) were calculated to compare the competing strategies. One-way, 2-way, and probabilistic sensitivity analyses with 100 000 iterations were performed to account for effects of uncertainty in model inputs. RESULTS Base case model demonstrated CDNT effectiveness, yielding an expected 21.04 lifetime QALYs, compared to 20.89 QALYs with GA, 19.68 QALYs with conservative management, and 19.15 QALYs with no treatment. The ICERs for CDNT, GA, and conservative management vs nontreatment were $5776.73/QALY, $10 483.52/QALY, and $882.47/QALY, respectively. Adjusting for potential income associated with increased likelihood of returning to work after clinical recovery demonstrated CDNT as the dominant strategy, with ICER = -$56 459.54/QALY relative to nontreatment. Probabilistic sensitivity analysis showed CDNT cost-effectiveness at a willingness-to-pay threshold of $50 000/QALY in 78.47% and 81.97% of trials with and without income adjustment, respectively. Conservative management dominated in <1% of iterations. CONCLUSION CDNT and GA are cost-effective interventions to restore shoulder function in patients with UBPI.

Abstract
The current health-care system in the United States has numerous barriers to quality, accessible, and affordable musculoskeletal care for multiple subgroups of our population. These hurdles include complex cultural, educational, and socioeconomic factors. Tertiary referral centers provide a disproportionately large amount of the care for the uninsured and underinsured members of our society. These gaps in access to care for certain subgroups lead to inappropriate emergency room usage, lengthy hospitalizations, increased administrative load, lost productivity, and avoidable complications and/or deaths, which all represent a needless burden on our health-care system. Through advocacy, policy changes, workforce diversification, and practice changes, orthopaedic surgeons have a responsibility to seek solutions to improve access to quality and affordable musculoskeletal care for the communities that they serve.

Abstract
BACKGROUND There is variability in access to and utilization of orthopaedic care, particularly for those with Medicaid insurance. One potential contributor is perceived unwillingness of surgeons and hospitals to accept underinsured patients. We used administrative data to examine the payer mix for select inpatient orthopaedic surgical procedures at all hospitals within a single region, hypothesizing that the delivery of orthopaedic surgery to Medicaid beneficiaries varies highly at the hospital level. METHODS Using administrative data, we analyzed inpatient hospitalizations for elective cases (total knee or hip arthroplasty; spinal decompression or fusion) and trauma cases (hip hemiarthroplasty; femoral or tibial and fibular fracture repair) among 22 hospitals in a single region from 2011 to 2016 for patients who were 18 to 64 years of age. The primary outcome was the percentage of each hospital's caseload with Medicaid listed as the primary payer. The secondary outcome measured each hospital's Medicaid percentage against the percentage of Medicaid-insured individuals within 10 miles of the hospital (Medicaid share ratio), using a ratio of 1 as a benchmark. To quantify variation, we calculated a weighted coefficient of variation of the Medicaid share ratio for all cases combined, elective cases only, and trauma cases only. RESULTS For all cases (n = 19,204), the mean percentage of Medicaid-funded surgical procedures was 7.6% (range, 0.2% to 57.3%). The mean Medicaid share ratio was 1.0 (range, 0.05 to 4.20). Across 22 hospitals, the weighted coefficient of variation for Medicaid share was 69, indicating very high variation. For elective cases alone, the mean percentage of Medicaid-funded surgical procedures was 5.5% (range, 0.2% to 64.6%). The mean Medicaid share ratio was 0.71 (range, 0.05 to 4.73), and the weighted coefficient of variation was 93. For trauma cases alone, Medicaid-funded surgical procedures were 14.7% (range, 0.0% to 35.7%). The mean Medicaid share ratio was 2.0 (range, 0 to 3.93), and the weighted coefficient of variation was 34. CONCLUSIONS Delivery of care was highly variable when benchmarking against the insurance composition of each hospital's surrounding community. Although generalizability to other regions is limited, our findings support previously asserted notions that delivery of orthopaedic care may differ on the basis of socioeconomic markers (such as insurance status). If not addressed, these inequities may exacerbate existing racially and socioeconomically based disparities in care.

Abstract
BACKGROUND Traumatic brachial plexus injuries (BPIs) disproportionately affect young, able-bodied individuals. Beyond direct costs associated with medical treatment, there are far-reaching indirect costs related to disability and lost productivity. Our objective was to estimate per-patient indirect cost associated with BPI. METHODS We estimated indirect costs as the sum of (1) short-term wage loss, (2) long-term wage loss, and (3) disability payments. Short-term (6-month) wage loss was the product of missed work days and the average earnings per day. The probability of return to work was derived from a systematic review of the literature, and long-term wage loss and disability payments were estimated. Monte Carlo simulation was used to perform a sensitivity analysis of long-term wage loss by varying age, sex, and return to work simultaneously. Disability benefits were estimated from U.S. Social Security Administration data. All cost estimates are in 2018 U.S. dollars. RESULTS A systematic review of the literature demonstrated that the patients with BPI had a mean age of 26.4 years, 90.5% were male, and manual labor was the most represented occupation. On the basis on these demographics, our base case was a 26-year-old American man working as a manual laborer prior to BPI, with an annual wage of $36,590. Monte Carlo simulation estimated a short-term wage loss of $22,740, a long-term wage loss of $737,551, and disability benefits of $353,671. The mean total indirect cost of traumatic BPI in the Monte Carlo simulations was $1,113,962 per patient over the post-injury lifetime (median: $801,723, interquartile range: $22,740 to $2,350,979). If the probability of the patient returning to work at a different, lower-paying job was doubled, the per-patient total indirect cost was $867,987. CONCLUSIONS BPI can have a far-reaching economic impact on both individuals and society. If surgical reconstruction enables patients with a BPI to return to work, the indirect cost of this injury decreases. LEVEL OF EVIDENCE Economic Level IV.

Abstract
BACKGROUND Although Medicaid expansion has improved access to primary care services, its impact on surgical specialty utilization remains unclear. The aim of this study is to determine whether Medicaid expansion is associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid). METHODS Using administrative data sources, we analyzed 374,877 total hospitalizations (236,333 in Illinois and 138,544 in Missouri) for THA/TKA from 2011 to 2016 (Illinois' Medicaid expansion date: January 1, 2014). RESULTS The percentage of THA/TKA funded by Medicaid in Illinois was 2.4% in 2013 and 3.9% in 2016 (Missouri 2013: 2.7%; 2016: 2.6%). A difference-in-difference analysis (adjusted for patient age and gender, county-level Area Deprivation Index, and number of orthopedic surgeons) demonstrated a statistically significant increase in Medicaid-funded THA/TKA in Illinois in 2016 compared to 2013 (P = .012). CONCLUSION Our study demonstrates that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. Further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.

Abstract
BACKGROUND The Internet is a widely used resource by patients however, objective data on details such as frequency of usage and specific sites visited is lacking. We surveyed patients from hand surgery practices to describe patient preferences and utilization patterns for online resources. METHODS From October 2015 to June 2016, we enrolled patients presenting to 4 orthopedic hand surgeons at 2 academic institutions. Patients completed a survey, with questions related to their preference for learning about their diagnosis and Internet utilization both before and after the visit. RESULTS A total of 226 patients were enrolled in the study. Forty-five percent of the patients had done online research prior to the office visit, and 81% preferred to learn about their diagnosis through verbal communication, as opposed to only 8% who listed Web site information. Fifty percent indicated that there was a greater than 50% chance or they would definitely seek additional information on the Internet after the office visit. When asked to choose from a list of Web sites to visit, the most popular Web site was WebMD. Specialty society Web sites (American Society for Surgery of the Hand and American Academy of Orthopaedic Surgeons) were less popular. CONCLUSIONS This survey-based study found that a majority of patients utilize the Internet both before and after the office visit; however, they often utilize unregulated sites for information. This information can help physicians guide patients to high-quality Web sites for information on their clinical diagnosis and treatment.

Abstract
BACKGROUND Overlapping surgery occurs when a single surgeon is the primary surgeon for >1 patient in separate operating rooms simultaneously. The surgeon is present for the critical portions of each patient's operation although not present for the entirety of the case. While overlapping surgery has been widely utilized across surgical subspecialties, few large studies have compared the safety of overlapping and nonoverlapping surgery. METHODS In this retrospective cohort study, we reviewed the charts of patients who had undergone orthopaedic surgery at our ambulatory surgery center during the period of April 2009 and October 2015. A database of operations, including patient and surgical characteristics, was compiled. Complications had been identified and logged into the database by surgeons monthly over the study period. These monthly reports and case logs were reviewed retrospectively to identify complications. Propensity-score weighting and logistic regression models were used to determine the association between outcomes and overlapping surgery. RESULTS A total of 22,220 operations were included. Of these, 5,198 (23%) were overlapping, and 17,022 (77%) were nonoverlapping. The median duration of surgery overlap was 8 minutes (quartile 1 to quartile 3, 3 to 16 minutes); no operations were concurrent. After weighting, the only continuous variables that differed significantly between the groups were operative time (median, 57 compared with 56 minutes for the overlapping and the nonoverlapping group, respectively; p = 0.022), anesthesia time (median, 97 compared with 93 minutes; p < 0.001), and total tourniquet time (median, 26 compared with 22 minutes; p = 0.0093). Multivariable logistic regression models did not demonstrate an association between overlapping surgery and surgical site infection, noninfection surgical complications, hospitalization, or morbidity. CONCLUSIONS These data suggest that there is no association between briefly overlapping surgery and surgical site infection, noninfection surgical complications, hospitalization, and morbidity. When practiced in the manner described herein, overlapping orthopaedic surgery can be a safe practice in the ambulatory setting. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
BACKGROUND Overlapping surgery is attracting increased scrutiny. The American College of Surgeons states that the attending surgeon must be present for all critical portions of a surgical procedure; however, critical portions of surgical procedures are not defined. We hypothesized that a Delphi panel process would measure consensus on critical portions of 3 common hand surgical procedures. METHODS We used a Delphi process to achieve consensus on the critical portions of carpal tunnel release, ulnar nerve transposition, and open reduction and internal fixation of the distal part of the radius. The panelists were 10 hand surgeons (7 fellowship-trained surgeons and 3 fellows). Following an in-person discussion to finalize steps for each procedure, 2 online rounds were completed to rate steps from 1 (not critical) to 9 (extremely critical). We operationalized consensus as ≥80% of ratings within the same range: 1 to 3 (not critical), 4 to 6 (somewhat critical), and 7 to 9 (critical). Because of a lack of consensus on some steps after round 2, another in-person discussion and a third online round were conducted to rate only steps involving disagreement or somewhat critical ratings using a dichotomous scale (critical or not critical). RESULTS Following the first 2 rounds, there was consensus on 19 of 24 steps (including 3 steps being somewhat critical) and no consensus on 5 of 24 steps. At the end of round 3, there was consensus on all but 2 steps (identification of the medial antebrachial cutaneous nerve in ulnar nerve transposition and clinical assessment of joint stability in open reduction and internal fixation of the distal part of the radius), with moderate disagreement (3 compared with 7) for both. CONCLUSIONS The panel reached consensus on the designation of critical or noncritical for all steps of a carpal tunnel release, all but 1 step of an ulnar nerve transposition, and all but 1 step of open reduction and internal fixation of the distal part of the radius. The lack of consensus on whether 2 of the steps are critical leaves this determination at the discretion of the attending surgeon. The findings of our Delphi panel provide guidance to our division on which portions of the surgical procedure are critical and thus require the attending surgeon's presence.

Abstract
PURPOSE Reactive depression and anxiety are common after major life changes such as brachial plexus injuries (BPI). The purpose of this study was to evaluate the incidence and risk factors for coded depression and coded anxiety among patients with BPI using a national database of commercial insurance claims. METHODS We used the Truven MarketScan database from 2007 to 2013 to identify commercially insured patients aged 18 to 64 years who underwent BPI surgery. For comparison, a control group without BPI was frequency-matched 10:1 by age group, sex, number of provider visits, and length of insurance enrollment. Using International Classification of Diseases, Ninth Revision diagnosis codes and pharmacy claims, we identified coded depression and coded anxiety in the 12 months before and 12 months after BPI surgery. Multivariable Cox regression models were used to determine risk factors for coded depression or coded anxiety, adjusting for known risk factors for depression or anxiety (eg, alcohol, substance abuse). RESULTS We identified 1,843 patients with BPI and 18,430 controls. Within the 12 months preceding surgery, coded depression and coded anxiety were present in 38% and 42%, respectively, of the BPI group; both were present in 25% and either was present in 54%. The rate of new-onset/postoperatively coded depression among patients with BPI was 142.1/1,000 person-years (12%) and of new-onset/postoperatively coded anxiety was 273.6/1,000 person-years (20%). Patients with BPI were significantly more likely than controls to develop new-onset/postoperatively coded depression (hazard ratio = 1.3; confidence interval [CI], 1.1-1.5) and new-onset/postoperatively coded anxiety (HR = 2.1 [CI, 1.8-2.4]). CONCLUSIONS Patients undergoing BPI surgery have a high prevalence of coded depression and coded anxiety in the 12 months before surgery and are at higher risk for developing new-onset/postoperatively coded depression and coded anxiety within 1 year after surgery. These findings can be used by BPI surgeons to inform perioperative counseling, guide emotional recovery from injury, and facilitate coordinated or colocated care with mental health professionals.

Abstract
BACKGROUND Although overlapping surgery is used to maximize efficiency, more empirical data are needed to guide patient safety. We conducted a retrospective cohort study to evaluate the safety of overlapping inpatient orthopaedic surgery, as judged by the occurrence of perioperative complications. METHODS All inpatient orthopaedic surgical procedures performed at 5 academic institutions from January 1, 2015, to December 31, 2015, were included. Overlapping surgery was defined as 2 skin incisions open simultaneously for 1 surgeon. In comparing patients who underwent overlapping surgery with those who underwent non-overlapping surgery, the primary outcome was the occurrence of a perioperative complication within 30 days of the surgical procedure, and secondary outcomes included all-cause 30-day readmission, length of stay, and mortality. To determine if there was an association between overlapping surgery and a perioperative complication, we tested for non-inferiority of overlapping surgery, assuming a null hypothesis of an increased risk of 50%. We used an inverse probability of treatment weighted regression model adjusted for institution, procedure type, demographic characteristics (age, sex, race, comorbidities), admission type, admission severity of illness, and clustering by surgeon. RESULTS Among 14,135 cases, the frequency of overlapping surgery was 40%. The frequencies of perioperative complications were 1% in the overlapping surgery group and 2% in the non-overlapping surgery group. The overlapping surgery group was non-inferior to the non-overlapping surgery group (odds ratio [OR], 0.61 [90% confidence interval (CI), 0.45 to 0.83]; p < 0.001), with reduced odds of perioperative complications (OR, 0.61 [95% CI, 0.43 to 0.88]; p = 0.009). For secondary outcomes, there was a significantly lower chance of all-cause 30-day readmission in the overlapping surgery group (OR, 0.67 [95% CI, 0.52 to 0.87]; p = 0.003) and shorter length of stay (e, 0.94 [95% CI, 0.89 to 0.99]; p = 0.012). There was no difference in mortality. CONCLUSIONS Our results suggest that overlapping inpatient orthopaedic surgery does not introduce additional perioperative risk for the complications that we evaluated. The suitability of this practice should be determined by individual surgeons on a case-by-case basis with appropriate informed consent. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
BACKGROUND Scaphoid fractures treated non-operatively and operatively may be complicated by nonunion. QUESTIONS/PURPOSES We sought to test the primary hypothesis that the incidence density of scaphoid fracture treatment is higher than previously estimated, to determine the frequency and risk factors for nonunion treatment, and to determine whether the frequency of surgical treatment increased over time. METHODS The MarketScan® database was queried for all records of treatment (casting and surgery) for closed scaphoid fractures over a 6-year period. We examined subsequent claims to determine frequency of additional procedures for nonunion treatment (revision fixation or vascularized grafting occurring 28 days or more after initial treatment). Trend analyses were used to determine whether changes in frequency of surgical treatment or revision procedure occurred. RESULTS The estimated incidence density of scaphoid fracture is 10.6 per 100,000 person-years in a commercially insured population of less than 65 years of age. Of 8923 closed scaphoid fractures, 29 and 71% were treated with surgery and casting, respectively. The frequency of surgical treatment rose significantly, from 22.1% in 2006 to 34.1% in 2012. The frequency of nonunion treatment was 10.8% after surgery and 3% after casting; neither changed over time. Younger age, male sex, and surgical treatment are associated with a higher risk of nonunion treatment. CONCLUSIONS Our estimated incidence of scaphoid fracture is higher than previously reported. The increased enthusiasm in the USA to surgically treat scaphoid fractures is reflected by our trend analysis. The frequency of surgical treatment for presumed nonunion after initial surgical management for closed scaphoid fractures exceeded 10%. Given the increased utilization of surgery, surgeons and patients should be aware of the frequency of nonunion treatment to inform treatment decisions.

Abstract
PURPOSE To determine whether the arthroscopic hook and trampoline tests are accurate and reliable diagnostic tests for foveal triangular fibrocartilage complex (TFCC) detachment. METHODS Wrist arthroscopy was performed on 10 cadaveric upper extremities. Arthroscopic hook and trampoline tests were performed and videos recorded (baseline). The deep foveal TFCC insertion was then sharply detached. Arthroscopic hook and trampoline tests were repeated. Subsequently, the foveal detachment was repaired via an ulnar tunnel technique and the hook test was repeated for a third time. Videos were independently reviewed at 2 time points by 2 fellowship-trained hand surgeons and 1 hand surgery fellow in a randomized and blinded fashion. Hook and trampoline tests were graded as positive or negative. Proportions of categorical variables were compared via 2-tailed Fisher exact test. Inter- and intraobserver reliabilities were assessed via Cohen kappa coefficient. RESULTS The sensitivity and specificity of the hook test for foveal detachment diagnosis were 90% and 90%, respectively. There was 90% agreement among all 3 observers for the baseline and foveal detachment hook tests. Cohen kappa coefficients for the inter- and intraobserver reliabilities of the hook test were 0.87 and 0.81, respectively. Seventeen percent of trampoline tests were positive at baseline versus 43% after foveal detachment. The trampoline test had 45% agreement between the 3 observers. Cohen kappa coefficients for the inter- and intraobserver reliabilities of the trampoline test were 0.16 and 0.63, respectively. Following ulnar tunnel repair, 20% of hook tests were positive. CONCLUSIONS The hook test is highly sensitive, specific, and reliable for the diagnosis of isolated TFCC foveal detachment. The trampoline test has insufficient reliability to assess foveal detachment. A TFCC foveal repair using an ulnar tunnel technique returns the hook test to baseline. CLINICAL RELEVANCE The hook test is a sensitive, specific, and reliable test for the diagnosis of isolated TFCC foveal detachment.

J Hand Surg Am 2018; 43:448-454. [PMID: 29395586 PMCID: PMC5936475 DOI: 10.1016/j.jhsa.2017.12.018] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2017] [Revised: 10/20/2017] [Accepted: 12/15/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE Although volar plating of the distal radius is performed frequently, the necessity of distal bicortical fixation in the metaphyseal and epiphyseal areas of the distal radius has not been proven. This study aimed primarily to quantify the ability of unicortical distal screws to maintain operative reduction of adult distal radius fractures and secondarily to determine if unicortical screw lengths could be predicted based on anatomical measurements. METHODS This prospective trial enrolled 75 adult patients undergoing volar locking plate fixation of a unilateral distal radius fracture at a tertiary center. Study inclusion required screw fixation in the distal rows of the plate performed with unicortical screw placement. The primary outcome was maintenance of operative reduction, according to predefined parameters, quantified by comparing initial operative reduction to final reduction after fracture healing. Repeated measures analysis of variance analyzed for systematic change in radiographic parameters between injury, operative, and healed images. Correlation coefficients quantified the relationship of screw lengths with lunate width and other anatomical measurements. RESULTS Seventy-five patients (mean age, 54 years ± 15 years; 79% women) were enrolled and followed to fracture union. Fracture severity varied and included AO type A (40%), B (12%), and C (48%) fractures. There was no significant change in mean lateral translation, intra-articular gap, intra-articular stepoff, radial inclination, or lateral tilt of the radius between the time of fixation and union for the cohort. Two patients lost reduction (increased dorsal tilt, 10°, 20°, respectively), potentially attributable to provision of unicortical fixation (3%; 95% confidence interval [95% CI], 0%-9%). No extensor tenosynovitis or extensor tendon ruptures occurred. Eighty percent of screws were 18 mm or less and screw lengths were not correlated with lunate width or any other anatomical measurements. CONCLUSIONS Unicortical distal fixation during volar locking plate fixation effectively maintains operative reductions of distal radius fractures while potentially minimizing the incidence of extensor tendon ruptures. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Background Existing scapholunate interosseous ligament (SLIL) reconstruction techniques include fixation spanning the radiocarpal joint, which do not reduce the volar aspect of the scapholunate interval and may limit wrist motion. Questions/Purpose This study tested the ability of an SLIL reconstruction technique that approximates both the volar and dorsal scapholunate intervals, without spanning the radiocarpal joint, to restore static scapholunate relationships. Materials and Methods Scapholunate interval, scapholunate angle, and radiolunate angle were measured in nine human cadaveric specimens with the SLIL intact, sectioned, and reconstructed. Fluoroscopic images were obtained in six wrist positions. The reconstruction was performed by passing tendon graft through bone tunnels from the dorsal surface toward the volar corner of the interosseous surface. After reduction of the scapholunate articulation, the graft was tensioned within the lunate bone tunnel, secured with an interference screw in the scaphoid, and sutured to the dorsal SLIL remnant. Differences among testing states were evaluated using repeated measures ANOVA. Results There was a significant increase in the scapholunate interval in all wrist positions after complete SLIL disruption. Compared with the disrupted state, there was a significant decrease in scapholunate interval in all wrist positions after reconstruction using a tendon graft and interference screw. Conclusion Our SLIL reconstruction technique reconstructs the volar and dorsal ligaments of the scapholunate joint and adequately restores static measures of scapholunate stability. This technique does not tether the radiocarpal joint and aims to optimize volar reduction. Clinical Relevance Our technique offers an alternative option for SLIL reconstruction that successfully restores static scapholunate relationships.

Abstract
The physiological limitations of neural regeneration make peripheral nerve surgery challenging to both the surgeon and the patient. Presence of nerve gaps and local wound factors may all influence outcome, suggesting that barriers to reduce perineural scarring, minimize fibrosis, and avoid ischemia would be beneficial. To examine the evidence supporting their use, we reviewed the autologous and commercially-available options for barriers against scarring around a nerve. Numerous clinical case series demonstrated the effectiveness and safety of local/rotational flaps and autologous vein wrapping when used in the presence of recurrent compressive neuropathy. Translational research in animal models supports the biocompatibility of commercially available nerve wraps following nerve repair. To date, there are no reports of clinical use of commercially available nerve wraps in acute nerve repair, but a growing number of case series demonstrate their effectiveness and safety in chronic compressive neuropathy. Limited clinical evidence exists to support the efficacy of vein or flap coverage in acute nerve repairs.

Abstract
BACKGROUND Medicaid reimbursements are determined by each state and are subject to variability. We sought to quantify this variation for commonly performed inpatient orthopaedic procedures. METHODS The 10 most commonly performed inpatient orthopaedic procedures, as ranked by the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample, were identified for study. Medicaid reimbursement amounts for those procedures were benchmarked to state Medicare reimbursement amounts in 3 ways: (1) ratio, (2) dollar difference, and (3) dollar difference divided by the relative value unit (RVU) amount. Variability was quantified by determining the range and coefficient of variation for those reimbursement amounts. RESULTS The range of variability of Medicaid reimbursements among states exceeded $1,500 for all 10 procedures. The coefficients of variation ranged from 0.32 (hip hemiarthroplasty) to 0.57 (posterior or posterolateral lumbar interbody arthrodesis) (a higher coefficient indicates greater variability), compared with 0.07 for Medicare reimbursements for all 10 procedures. Adjusted as a dollar difference between Medicaid and Medicare per RVU, the median values ranged from -$8/RVU (total knee arthroplasty) to -$17/RVU (open reduction and internal fixation of the femur). CONCLUSIONS Variability of Medicaid reimbursement for inpatient orthopaedic procedures among states is substantial. This variation becomes especially remarkable given recent policy shifts toward focusing reimbursements on value.

Abstract
BACKGROUND The physical and psychological impact of brachial plexus injury (BPI) has not been comprehensively measured with BPI-specific scales. Our objective was to develop and test a patient-derived questionnaire to measure the impact and outcomes of BPI. METHODS We developed a questionnaire in 3 phases with preoperative and postoperative patients. Phase 1 included interviews of patients using open-ended questions addressing the impact of BPI and improvement expected (preoperative patients) or received (postoperative patients). Phase 2 involved assembling a draft questionnaire and administering the questionnaire twice to establish test-retest reliability. Phase 3 involved selecting final items, developing a scoring system, and assessing validity. Patient scores using the questionnaire were assessed in comparison with scores of the Disabilities of the Arm, Shoulder and Hand (DASH) and RAND-36 measures. RESULTS Patients with partial or complete plexopathy participated. In Phase 1 (23 patients), discrete categories were discerned from open-ended responses and became items for the preoperative and postoperative versions of the questionnaire. In Phase 2 (50 patients [14 from Phase 1]), test-retest reliability was established, with weighted kappa values of ≥0.50 for all items. In Phase 3, 43 items were retained and grouped into 4 subscales: symptoms, limitations, emotion, and improvement expected (preoperative) or improvement received (postoperative). A score for each subscale, ranging from 0 to 100, can be calculated, with higher scores indicating more symptoms, limitations, and emotional distress, and greater improvement expected (or received). Preoperative scores were worse than postoperative scores for the symptoms, limitations, and emotion subscales (composite score of 48 compared with 38; p = 0.05), and more improvement was expected than was received (69 compared with 53; p = 0.01). Correlations with the DASH (0.44 to 0.74) and RAND-36 (0.23 to 0.80) for related scales were consistent and moderate, indicating that the new questionnaire is valid and distinct. CONCLUSIONS We developed a patient-derived questionnaire that measures the physical and psychological impact of BPI on preoperative and postoperative patients and the amount of improvement expected or received from surgery. This BPI-specific questionnaire enhances the comprehensive assessment of this population.
