Background: Computer-assisted navigation (CAN) offers dynamic intraoperative guidance in total ankle arthroplasty (TAA). Although laboratory data suggest superior precision, in vivo evidence is lacking. This study used weightbearing computed tomography (WBCT) to evaluate CAN accuracy of postoperative TAA implant position relative to the plan. We hypothesized that absolute discrepancies would be <3 mm or <3°. Methods: Thirteen consecutive patients (November 2024–November 2025) underwent TAA using CAN. Preoperative computed tomography–based 3D models were used for templating. Postoperative WBCT scans were used to measure final implant seating, and computerized measurements were used to identify implant placement discrepancy. We analyzed absolute discrepancies between planned vs final postoperative positions. Results: Tibial absolute discrepancies were within desired limits for varus/valgus (1.65° ± 1.43°), slope (1.87° ± 1.34°), and cut height (0.68 ± 0.62 mm) but not for axial rotation (3.97 ± 2.64). For the talus, varus/valgus (2.93° ± 1.86°) and cut height (0.66 ± 0.71 mm) absolute discrepancies were within desired limits. The increased talar slope deviation (3.90 ± 2.89) in the final position may be due to non-navigated implant impaction. Conclusion: Although discrepancies persisted in tibial rotational alignment and talar positioning, the low variability across measurements suggests that CAN may support accurate implant positioning. These short-term positioning accuracy findings support the utility of CAN as a potential tool for enhancing implant positioning reproducibility in TAA. Level of Evidence: Level IV, case series.

Primary sternal osteomyelitis (PSO) is an exceptionally rare infection of the sternum, typically occurring in the context of trauma, surgery or immunocompromise. We report the case of a previously healthy adolescent boy in his second decade of life presenting with fever, chest pain and localised tenderness without any identifiable risk factors. Initial workup, including a chest X-ray and echocardiogram, was unremarkable, but persistent bacteraemia with methicillin-sensitive Staphylococcus aureus prompted further imaging. MRI revealed sternal osteomyelitis with a small parasternal abscess. The patient was successfully treated with intravenous antibiotics alone, avoiding surgical intervention. This case highlights the importance of thorough physical examination and maintaining a high index of suspicion for PSO in patients with unexplained fever and chest wall tenderness, even in the absence of traditional risk factors. Early diagnosis and targeted therapy are essential to optimise outcomes in this rare condition.

Abstract Background Little research exists regarding geographic comparisons within the United States for Medicaid reimbursement. We compared Medicaid reimbursement for a broad range of orthopedic surgery codes from each state on a geographic and state level. Methods We obtained Medicaid reimbursement rates in each state for 211 orthopedic procedure codes along with corresponding work Relative Value Units (wRVUs). Rates were divided by wRVUs to control for differences between procedures and subspecialties. States were designated as either West, Midwest, South, or Northeast. Kruskal-Wallis tests with Dunn’s post-hoc analyses ascertained differences between regions and each orthopedic subspecialty by state. Coefficient of variation (CoV) values were calculated to measure the amount of variability in rates. A Kruskall-Wallis with Dunn’s post-hoc test assessed differences in quartiles for reimbursement compared to a square miles per orthopedic surgeon ratio. Results The West region reimbursed the highest at $72.92/wRVU and the Northeast reimbursed the lowest at $51.78. Hand surgery was the highest reimbursing subspecialty ($94.58/wRVU) and Oncology the lowest ($62.89/wRVU). The CoV ranged from 0.15–0.77 by state and 0.27–0.50 by subspecialty. A linear regression model between wRVU-adjusted Medicaid reimbursement and square miles per surgeon yielded an R2 value of 0.453. States with the most land area relative to orthopedic surgeons reimbursed significantly higher. Conclusion The West geographic region is associated with the highest Medicaid reimbursement for orthopedic procedures, and the Northeast the lowest. Wide variability was seen in rates, both between states and within states. Large, sparsely-populated states may increase Medicaid reimbursement as a tactic to attract physicians.

Abstract Total wrist arthroplasty (TWA) is a motion-sparing surgical alternative to wrist arthrodesis for patients with radiocarpal arthritis, but prior reports have indicated that its utilization remains limited. This study aimed to quantify Medicare and Medicaid reimbursement for TWA, along with utilization trends for the procedure using Medicare data. Medicare and Medicaid reimbursement rates for three TWA Current Procedural Terminology (CPT) codes—25446 (TWA), 25332 (TWA with interposition), and 25449 (revision TWA)—were collected for all states except Tennessee for the year 2024 and compared with each other. Prior Medicare rates from 2000 to 2023 were also obtained, adjusted for inflation to represent 2024 dollars, and analyzed for reimbursement trends with a two-tailed t-test between average inflation-adjusted 2000 and 2024 reimbursement. Utilization data from 2000 to 2022 were obtained from the Medicare Part B database. Medicaid reimbursement averaged 16.8% less than Medicare across the three TWA codes, with high variability between states. Inflation-adjusted Medicare reimbursement decreased by an average of 44.2% from 2000 to 2024, with the greatest decline seen in CPT 25446 (TWA) with a 45.1% decrease. Reimbursement for all three codes had decreased significantly from 2000 to 2024 via the two-tailed t-test. Besides an initial dramatic fall from 2000 to 2021 for revision TWA, Medicare utilization gradually increased, with 25332 (TWA with interposition) being the most commonly billed code. TWA reimbursement has decreased significantly over the past two decades for Medicare. Current Medicaid reimbursement is substantially less than Medicare. Although utilization has increased modestly, low reimbursement, along with a variety of other factors, may contribute to a limited adoption of TWA. Addressing these disincentives may encourage further innovation and technological development in TWA.

Background: Total wrist arthrodesis is a well-established procedure providing pain relief and stability for patients with symptomatic radiocarpal arthritis refractory to nonoperative measures. Little research exists on reimbursement and utilization trends for this procedure. This study aimed to characterize Medicare reimbursement trends for total wrist arthrodesis, along with trends in Medicare utilization and comparison with Medicaid reimbursement. Methods: Medicare reimbursement for Current Procedural Terminology codes 25800, 25805, and 25810 were collected from the Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule from 2000 to 2025. Rates were inflation-adjusted to 2025 dollars, and percentage changes were calculated. Medicare utilization trends from 2000 to 2022 were analyzed using CMS Part B data. Most recent Medicaid reimbursement was collected from online state fee schedules and compared with 2025 Medicare rates, with additional analyses of variability and adjustment for work Relative Value Units. Results: Inflation-adjusted Medicare reimbursement for total wrist arthrodesis decreased by 49.1% from 2000 to 2025 ( P < .0001), averaging a 1.96% annual decline. Utilization trends remained stable, with wrist arthrodesis with iliac or other autograft (CPT 25810) being the most commonly billed procedure. Medicaid reimbursed 13.6% less than Medicare on average, with substantial state variability, ranging from 44.7% (New Hampshire) to 135.4% (Alaska) of Medicare reimbursement. Conclusion: Reimbursement for total wrist arthrodesis has declined significantly despite stable utilization in the Medicare population. Medicaid reimbursement is consistently lower and highly variable by state, potentially impacting access to care. Given the effectiveness of wrist arthrodesis, policymakers should advocate for equitable reimbursement for this procedure.

ABSTRACTBackground and ObjectivesMedicaid reimbursement to physicians has been demonstrated to be lower than reimbursement from Medicare and private insurance. Studies on Medicaid reimbursement for orthopedic oncology procedures, however, are limited. This study compares Medicaid reimbursement rates to Medicare for 38 common musculoskeletal oncology procedures and assesses variability among states.MethodsWe collected 38 current procedural terminology (CPT) codes for commonly performed orthopedic oncology procedures. Medicare rates were obtained from the 2023 Centers for Medicare and Medicaid physician (CMS) fee schedule. Medicaid rates were collected from electronic state website fee schedules. Reimbursement for the two insurance types were compared with state and national averages. Dollar differences were adjusted for work relative value units (RVU) to ascertain procedural variability. The Medicare Wage Index, representing differences in wages across states, was used to adjust medicaid rates to compare more accurately to medicare. Coefficient of variation values, calculated by dividing the standard deviation by the mean, were calculated to assess variation among procedures.ResultsMedicaid reimbursed orthopedic oncologists 22.1% less than medicare on average, increasing to 33.0% when adjusting for wage differences. State Medicaid reimbursement ranged from 37% to 131% of Medicare, with 38 states reimbursing less than Medicare on average. The coefficient of variation for Medicaid procedures ranged from 0.24 to 0.46, indicating wide variability among states and procedures, while for Medicare, the coefficient of variation was low at 0.06 to 0.07.ConclusionsMedicaid reimbursement for common orthopedic oncology procedures is substantially lower and more variable than Medicare, despite the often urgent nature of these surgeries. Disparities in reimbursement may impact access to care for this population, highlighting the need for policy reform.

Background: Medicaid reimbursement to physicians is often perceived to be lower than Medicare, but little is known about orthopaedic foot and ankle reimbursement. This study sought to compare Medicare and Medicaid reimbursement for the 20 most common foot and ankle procedures. Methods: Medicare reimbursement rates for common foot and ankle codes were obtained from the online Centers for Medicare & Medicaid fee schedule, while Medicaid rates were found from individual state fee schedule websites. Medicaid rates were compared by state and pooled to obtain national differences. The Medicare Wage Index was used to adjust Medicaid rates by state wages to ensure a more accurate comparison. Variability between states was measured using state percentages of Medicare and coefficient of variation values. Results: Medicaid reimbursed physicians higher than Medicare in 31 states overall, with average reimbursement ranging from 37% to 324% of Medicare. Nationally, Medicaid reimbursed 8.8% higher than Medicare, but Medicare reimbursed 3.7% higher when adjusted for the Medicare Wage Index. The Current Procedural Terminology ( CPT ) codes with the highest ratio of Medicaid to Medicare reimbursement were CPT 28002 for incision and drainage of the foot (176.6%) and CPT 28820 for toe amputation (167.6%). Five codes had lower relative Medicaid reimbursement on average: CPT 27687 for repair procedures on the leg and ankle joint, CPT 28810 for amputation procedures on the foot and toes, CPT 28010 for toe tenotomy, CPT 28005 for incision procedures on the foot and toes, and CPT 28470 for closed treatment of a metatarsal fracture. The coefficient of variation values ranged from 0.34 to 0.84 in the Medicaid group and 0.40 to 0.78 in the adjusted group, indicating high variability between states and between procedures. Conclusion: Medicaid reimbursement is highly inconsistent between states, ranging from 37% to 324% of Medicare. Medicaid reimbursed more than Medicare overall, which is in contrast with most published findings that tend to show higher reimbursement for Medicare when compared to Medicaid. When adjusting for wage differences between states, Medicare reimbursed slightly higher than Medicaid. Level of Evidence: Level IV, economic analysis.

Purpose To compare Medicaid and Medicare rates for the 20 most commonly billed orthopaedic sports medicine procedures. Methods Medicaid reimbursement rates were obtained from state‐specific fee schedules. Medicare rates were collected from the Centers for Medicare & Medicaid Services Physician Fee Schedule, along with relative value units for each procedure. State rates were compared using averages and dollar differences. Reimbursement rates were adjusted for cost of living using the Medicare Wage Index. Variability between states and between procedures was assessed using coefficients of variation. Results Mean Medicaid reimbursement was lower than that of Medicare for 19 of the 20 procedures. In total, Medicaid reimbursed surgeons 14.9% less when data were unadjusted and 26.0% less when data were adjusted for cost of living. Variation in Medicare rates between states was constant, with a coefficient of variation of 0.06. For Medicaid, the coefficients of variation ranged from 0.27 to 0.70 for unadjusted data and from 0.35 to 0.69 for adjusted data. Conclusions On average, Medicaid reimburses orthopaedic sports medicine specialists less than does Medicare, with substantial variability between states. Adjustment for cost of living increases the percentage difference and the variability between states’ Medicaid reimbursement rates. Level of Evidence Level IV, economic analysis.
