3D Topographical Scanning for the Detection of Osteoporosis.

Objectives: Osteoporosis is associated with greater risk of fracture, which can lead to increased morbidity and mortality. DEXA scans are often inaccessible for patients, leaving many cases of osteoporosis undetected. A portable 3D topographical scan offers an easily accessible and inexpensive potential adjunct screening tool. We hypothesized that 3D scanning of arm and calf circumference and volume would correlate with DEXA T-scores. Methods: 96 female patients were enrolled. Patients were consented and completed a topographical scan of bilateral arms and lower legs with a mobile 3D scanner for arm and calf circumference and volume in clinic. Patient charts were then retrospectively reviewed for DEXA T-scores. Results: Forearm DEXA T-score was positively correlated with arm circumference (r = 0.49, p<0.01), arm volume (r=0.62, p<0.01), and calf volume (r=0.47, p<0.01). Femoral neck DEXA T-score was positively correlated with calf circumference (r=0.36, p<0.01) and calf volume (r=0.36, p<0.01). Conclusions: Our results showed significant correlations between DEXA T-scores and topographical measurements from mobile device acquired 3D scans, although these were in the "moderate" range. Mobile device-based 3D scanning may hold promise as an adjunct screening tool for osteoporosis when DEXA scanning is not available or feasible for patients, although further studies are needed to elucidate the full potential of its clinical utility. At a minimum, identifying a patient as high risk may promote earlier diagnostic DEXA scanning.

Out-of-Pocket and Total Costs for Common Hand Procedures From 2008 to 2016: A Nationwide Claims Database Analysis.

PURPOSE: Rising patient out-of-pocket (OOP) costs and financial distress have been associated with reduced access to and delays in care. We evaluated whether OOP and total costs for common hand procedures have increased from 2008 to 2016 and identified key drivers of these costs. METHODS: Using the IBM MarketScan Research Databases, we identified patients who underwent trigger finger release, open carpal tunnel release, thumb carpometacarpal joint arthroplasty, cubital tunnel release, or open treatment of distal radius fracture in the outpatient setting between 2008 and 2016. Patient OOP costs included copayment, coinsurance, and deductible payments. Costs not directly related to medical care, such as transportation and childcare costs, were not included. The overall cost was defined as the sum of the patient OOP cost and insurer reimbursements. We calculated changes in OOP and total overall costs over the study period. We also performed multivariable linear regressions to evaluate the associations between costs and procedure type, insurance type, region, and site of service. RESULTS: The mean patient OOP cost increased by 55% to 71% and the total overall cost increased by 20% to 45%, depending on the procedure, between 2008 and 2016. Facility overall costs increased by 38%, whereas professional overall costs increased by 9%. Procedures performed in an office-based setting were associated with the lowest patient OOP and total overall costs, whereas high-deductible health plans were associated with the highest OOP costs. CONCLUSIONS: Patient OOP and total overall costs increased for the most common hand procedures between 2008 and 2016, driven by a substantial increase in facility costs. Office-based procedures were associated with the lowest costs. CLINICAL RELEVANCE: To alleviate the rising patient cost burden, hand surgeons could incorporate OOP cost considerations into shared decision-making tools, identify patients who may benefit from financial counseling, and shift procedures to an office-based setting.

ICD-10 codes do not accurately reflect ankle fracture injury patterns.

OBJECTIVE: To determine the accuracy of International Classification of Disease Version 10 (ICD-10) coding for ankle fracture injury patterns. DESIGN: Retrospective cohort study PATIENTS: 97 adult patients with fractures about the ankle (rotational ankle fracture or distal tibia fracture) from 2016 to 2020, selected by stratified random sampling. INTERVENTION: Assignment of an ICD-10 code representative of a rotational ankle fracture, pilon fracture, or unspecified fracture of the lower leg. OUTCOME MEASUREMENTS: Injury radiographs were reviewed by three authors to determine the correct code. Agreement between the correct code and the electronic medical record (EMR) assigned code was determined using kappa's statistic in the aggregate as well as percent agreement, sensitivity, specificity, and positive predictive value (PPV) between individual codes. RESULTS: 59 of 97 cases (60.8%) demonstrated discordance between the existing EMR and surgeon-assigned codes. Aggregate agreement between all codes was fair (K = 0.26). Lateral malleolus fracture codes demonstrated the highest PPV (0.91, 95% CI 0.72-0.99), while the lowest PPV was found for "other fractures of the lower leg" (0.05, 95% CI 0.0-0.24) and "other fracture of the fibula" (0.0, 95% CI 0.0-0.15). Generalized "other fracture" codes comprised 45% of EMR codes compared to only 6% of assigned codes (p < 0.001). EMR codes were specific but not sensitive. CONCLUSION: There is substantial discordance between existing EMR and surgeon-assigned ICD-10 codes for ankle fractures. Database research that relies on ICD-10 coding as a surrogate for primary clinical data should be interpreted with caution and institutions should make efforts to increase the accuracy of their coding.

Education research - Understanding the factors involved in inpatient communication for orthopedic trainees.

BACKGROUND: "Interpersonal and Communication Skills" (ICS) is a core competency set forth by the ACGME. No structured curriculum exists to train orthopedics residents in ICS. METHODS: Twenty-four out of thirty-five orthopedics residents completed the survey (69%). The survey had the following domains: [1] Demographics, [2] Communication Needs/Goals, and [3] Communication Barriers. RESULTS: Eighty-three percent of respondents wanted to improve their communication skills and their patient's experience. Interns-PGY4s wanted to improve on similar specific communication skills. All residents desired training in conflict management. CONCLUSION: There is a need among orthopedics residents for a communication skills curriculum early in residency training, specifically in conflict management.

One surgeon's learning curve with single position lateral lumbar interbody fusion: perioperative outcomes and complications.

BACKGROUND: Single position (SP) lateral transpsoas lumbar interbody fusion (LLIF) with posterior pedicle screw fixation (PPSF) reduces operative time compared to dual positioning. However, the learning curve has not yet been described. The purpose of this study was to define the learning curve SP LLIF with PPSF. METHODS: This retrospective case series included the first 161 consecutive patients who underwent SP LLIF and PPSF with the senior author. Primary analysis of operative time versus case number included single level cases without adjacent level procedures. Secondary analyses included 1-3 level cases without adjacent level procedures. Operative time for 2 and 3 level procedures was normalized to single-level cases. The learning curve was assessed with linear regression, which was found to fit the data better than logarithmic regression as judged by R2 values and data visualization. Perioperative outcomes as a function of case number were analyzed by least squares linear regression and Mann Whitney U-tests. RESULTS: For single level surgeries without adjacent procedures (n=87), operative time decreased by a total of 28.7 (95% CI, 9.6, 47.9) minutes over the series (P<0.001). For 1-3 level cases with no adjacent procedures (n=131), normalized operative time decreased by 23.1 (7.6, 38.6) minutes (P<0.001). Post-operative change in hematocrit, length of hospital stay, post-operative change in lordosis, 90-day complications, suboptimal screw placement, and 6-week post-operative Oswestry Disability Index (ODI) score did not correlate with case number. Intraoperative fluids decreased 3.7 mL (95% CI, 0.7, 6.7) per case (P=0.015). CONCLUSIONS: In SP LLIF with PPSF, case number correlated with decreased operative time, but not complications. The surgeon's prior experience with dual position (DP) LLIF likely contributed to the minimal learning curve observed. Surgeons adopting SP LLIF with minimal prior DP LLIF experience may experience a steeper curve.

Google Trends Analysis Shows Increasing Public Interest in Platelet-Rich Plasma Injections for Hip and Knee Osteoarthritis.

BACKGROUND: Osteoarthritis is a chronic musculoskeletal condition that frequently affects the hip and knee joints. Given the burden associated with surgical intervention for hip and knee osteoarthritis, patients continue to search for potential nonoperative treatments. One biologic therapy with mixed clinical and basic science evidence for treating osteoarthritis is platelet-rich plasma injections into the affected joint. We used the Google Trends tool to provide a quantitative analysis of national interest in platelet-rich plasma injections for hip and knee osteoarthritis. METHODS: Google Trends parameters were selected to obtain search data from January 2009 to December 2019. Various combinations of "arthritis," "osteoarthritis," "PRP," "platelet-rich plasma," "knee," and "hip" were entered into the Google Trends tool and trend analyses were performed. RESULTS: Three linear models were generated to display search volume trends in the United States for platelet-rich plasma and osteoarthritis, hip osteoarthritis, and knee osteoarthritis, respectively. All models showed increased Google queries as time progressed (P < .001), with R2 ranging from 0.837 to 0.940. Seasonal, income-related, and geographic variations in public interest in platelet-rich plasma for osteoarthritis were noted. CONCLUSION: Our results demonstrate a significant rise in Google queries related to platelet-rich plasma injections for osteoarthritis of the hip and knee since 2009. Surgeons treating hip and knee osteoarthritis patients can expect continued interest in platelet-rich plasma, despite inconclusive clinical and basic science data. Trends in public interest may inform patient counseling, shared decision-making, and directions for future clinical research.

Using Google Trends Data to Track Healthcare Use for Hand Osteoarthritis.

Background Google Trends (GT) is a free tool that provides analysis of search traffic for specified terms entered into the Google search engine. In this study, we evaluate the association between public interest in hand osteoarthritis (OA) as determined by GT search volumes and healthcare usage related to hand OA. Methodology We compiled GT data from 2010 to 2017 for the following group of hand OA-related search terms: "hand osteoarthritis," "hand arthritis," "hand swelling," "hand stiffness," and "chronic hand pain." Claims associated with hand OA codes were obtained from an administrative database (14.8 million patients) using International Classification of Diseases codes from 2010 to 2017. We performed trend analysis using univariate linear regression of GT data and hand OA claims. A month-by-month analysis of variation from yearly GT means was conducted for hand OA-related search terms. Results There was increased public interest in hand OA-related search terms from January 2010 to December 2017. Univariate linear regression of GT data for hand OA-related search terms compared with hand OA claims demonstrated a significant positive correlation (p < 0.001, r = 0.707). Peak public interest in hand OA-related search terms was observed in July, May, and June. Conclusions This study demonstrates the ability of GT to track healthcare use related to hand OA. Our data also add to the evidence for monthly variations in public interest related to hand OA. Clinics and surgery centers can employ GT data to anticipate resource utilization by hand OA patients.
