Background: While tobacco use is a well-known risk factor for adverse outcomes after carpal tunnel release (CTR), the impact of non-tobacco nicotine products remains unclear. This study evaluated complications in CTR patients with non-tobacco nicotine dependence (NTND) compared with tobacco users and controls. Methods: Patients who underwent CTR with ≥2-year follow-up were identified using a large national database. After 1:1 propensity score matching, patients with NTND (n = 6319) were matched to controls, tobacco users (n = 86 430) were matched to controls, and patients with NTND (n = 6325) were matched to tobacco users. Matching was based on age, gender, Charlson comorbidity index, and comorbidities. Outcomes including 90-day medical complications, infection, emergency department (ED) visits, readmissions, and 2-year revision rates were compared using multivariable logistic regression. Results: Compared with controls, patients with NTND demonstrated higher 90-day medical complication rates (2.4% vs 1.7%; odds ratio [OR], 1.35; 95% CI, 1.04-1.77) and ED visits (10.3% vs 8.1%; OR, 1.16; 95% CI, 1.02-1.32). Compared with tobacco users, patients with NTND had decreased ED visits (10.4% vs 14.2%; OR, 0.74; 95% CI, 0.66-0.83) and revision surgery (1.9% vs 2.5%; OR, 0.78; 95% CI, 0.62-0.99), with no significant differences in medical complications, infection, or readmissions. Conclusions: Non-tobacco nicotine dependence was associated with increased medical complications and ED visits compared with controls, but decreased ED visits and revision surgery compared with tobacco users. There were no significant differences in medical complications, infections, or readmissions between tobacco users and patients with NTND. These findings underscore the importance of screening for non-tobacco nicotine use during preoperative evaluations for CTR.

Abstract Distal radius fracture (DRF) open reduction and internal fixation (ORIF) is a common procedure performed across inpatient and outpatient settings. This study compared postoperative complications and healthcare utilization between these settings using a large national claims database. Patients aged 18 years and older who underwent DRF ORIF were identified in the PearlDiver Mariner database using International Classification of Diseases and Current Procedural Terminology codes. Service location determined surgical setting. Patients with pathological fractures, malignancy, or polytrauma were excluded. Cohorts were propensity matched 1:1 based on age, sex, Charlson and Elixhauser comorbidity indices, and relevant comorbidities. The matched cohort included 9,697 inpatient and 9,697 outpatient DRF ORIF cases. Serious postoperative complications occurred in 16.8% of inpatient procedures versus 5.0% of outpatient procedures. Inpatient surgery was associated with higher odds of surgical site infection (OR 2.23, 95% CI: 1.78–2.79), wound dehiscence (OR 2.57, 95% CI: 1.07–6.17), and deep vein thrombosis (OR 7.75, 95% CI: 3.53–17.04). Inpatients also had greater odds of emergency department visits (OR 1.17, 95% CI: 1.05–1.31), readmissions (OR 3.64, 95% CI: 2.91–4.54), reoperations (OR 2.15, 95% CI: 1.70–2.73), and higher 90-day reimbursements. Inpatient DRF ORIF was associated with significantly higher complication rates and increased postoperative healthcare utilization compared with outpatient procedures, with the largest absolute differences seen in readmissions, reoperations, and 90-day reimbursements. These associations are unlikely to be causal, as inpatient admission typically reflects greater medical necessity and clinical complexity not fully captured by administrative data. Nonetheless, because admission status is readily available at the point of care, it may serve as a practical flag to identify patients who warrant closer post-discharge surveillance and individualized follow-up planning.

Background: To our knowledge, there are no studies assessing associations between patients on preoperative estrogen replacement therapy (ERT) undergoing distal radius open reduction and internal fixation (DRORIF) and postoperative outcomes. Thus, the purpose of this study was to compare surgical and medical complications in patients on ERT undergoing DR-ORIF with a matched control cohort. Materials and Methods: The PearlDiver Mariner database was searched for female patients who took ERT within 3 months of the index procedure. Patients were matched 1:4 with non-ERT controls using propensity score matching. Complications were assessed at 90 days, 2 years, and 5 years. Statistical analyses were conducted using odds ratios (OR) with 95% confidence intervals (CI). Statistical significance was determined at a P value of <.05. Results: The ERT cohort consisted of 1,815 ERT users, and the control cohort consisted of 7,247 patients. At 2 years, the ERT cohort was associated with a slightly greater incidence of malunion/nonunion (OR, 1.57; 95% CI, 1.13–2.18) but with no increased risk of revision surgery (OR, 1.10; 95% CI, 0.50–2.10). Similarly, at 5 years, the ERT cohort was associated with a slightly higher likelihood of a malunion/nonunion diagnosis (OR, 1.69; 95% CI, 1.24–2.30). Conclusion: The current study suggests that patients on preoperative ERT had a slightly increased risk of malunion/nonunion at 2 years and 5 years after DR-ORIF. We did not find associations between increases in the risk of any other major or minor complications and the cohort of patients on preoperative ERT within 5 years postoperatively.

Background: Simultaneous carpal tunnel release (sCTR) with emergent forearm fasciotomy in the setting of acute compartment syndrome (ACS) has been reported, but the national incidence and cost of delayed carpal tunnel release (CTR) remain unknown. This large database study aims to evaluate how often sCTR is performed, the frequency of delayed CTR when not performed simultaneously, and the associated costs. Methods: The PearlDiver Mariner database was queried for patients who underwent forearm fasciotomies between January 1, 2015, and October 31, 2022. Patients were grouped based on CTR timing: simultaneous, within 2 weeks, 2 weeks to 1 year, 1 to 5 years, or no CTR. Reimbursement data were collected, and patient numbers and costs were analyzed across cohorts. Results: More than half of patients undergoing emergent forearm fasciotomy received sCTR. Among those who did not, 31% required CTR within 1 year and 35% within 5 years. The total cost was highest when CTR was performed within 1 year but not on the same day as fasciotomy. After 1 year, the additional cost of CTR was similar to that of patients who never underwent fasciotomy. Conclusions: This large database study shows that over one-third of patients who did not undergo sCTR at the time of emergent forearm fasciotomy required it within 1 year, incurring significantly higher costs. Including sCTR during initial fasciotomy may reduce delayed care and associated expenses. While these findings suggest that including sCTR during initial fasciotomy may reduce delayed care and expenses, the retrospective design precludes definitive recommendations, and clinical judgment remains essential Level of Evidence: 4

Abstract Despite the reported benefits of testosterone replacement therapy (TRT), prior studies have shown that TRT is correlated with increased incidence of adverse outcomes after orthopedic procedures. There is a paucity of literature assessing the outcomes of patients on preoperative TRT undergoing distal radius open reduction and internal fixation (DR-ORIF). Our purpose was to evaluate rates of surgical and medical complications in patients on TRT undergoing DR-ORIF with a matched control cohort. The PearlDiver database was queried for patients who used TRT within 3 months prior to the index procedure. Patients were matched 1:4 with nonuser controls using propensity score matching. Matching was conducted based on age, Elixhauser Comorbidity Index, hypogonadism, osteoporosis, and other comorbidities. Complications were assessed at 90 days and 2 years. Statistical analyses were conducted using chi-square tests. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for each complication. Statistical significance was determined at a p-value of < 0.05. The matched group included 657 TRT users and 2,236 controls. There were significant differences in depression (control: 40.6% vs. TRT: 45.7%, p = 0.02) and rates of hypogonadism (control: 74.1% vs. TRT: 77.9%, p = 0.05) between the groups. No other statistically significant demographic or characteristic differences were noted. TRT use was not associated with increased surgical or medical complication rates at 90 days postoperatively. At 2 years, TRT use was associated with a greater incidence of revision (OR: 2.80, 95% CI: 1.34–5.85) and nonunion (OR: 2.76, 95% CI: 1.59–4.81). There were no other associations noted at 2 years. Preoperative TRT was associated with an increased risk of revision surgery and nonunion at 2 years postoperatively. No other significant associations in the risk of major or minor complications were observed. Level III

Background: The aim of this study was to evaluate the prevalence and perceived efficacy of cannabidiol (CBD) products in patients presenting to an orthopedic hand and upper extremity clinic. Materials and Methods: New patients seen for an initial surgical consultation between July and December 2022 were surveyed regarding CBD use, pain, and function. Pain was measured with the Numeric Pain Rating Scale (NPRS, 0–10) and function with the Single Assessment Numeric Evaluation (SANE, 0–100). Demographic and clinical factors were collected via chart review. Results: A total of 918 patients completed the survey (53% female; mean age 63 years, range 18–97). Joints involved included elbows (106), wrists (335), and hands/fingers (667). Common diagnoses included arthritis (199), tendinopathy (273), and nerve-related conditions (160). Overall, 15% (135/918) reported prior CBD use, and 39% (53/135) perceived pain relief. CBD users were more likely to be female (65% vs 51%; P =0.003), to present with wrist pathology (44% vs 35%; P =0.038), and to have arthritis (36% vs 19%; P <0.001). Compared to non-users, CBD users reported higher pain scores (mean NPRS 6.2 vs 5.1; P <0.001) and lower contralateral function (mean SANE 77.3 vs 87.4; P <0.001). Conclusions In this cohort, CBD use was uncommon, and only a minority of users reported subjective benefit. CBD users tended to report higher pain and worse function, particularly in the setting of wrist arthritis. CBD products did not appear to provide measurable objective improvement in pain or function. Further studies are needed to clarify optimal dosing, administration, and potential role in upper extremity care.

Background Carpal tunnel release (CTR) is one of the most frequently performed procedures in the United States, with both open (OCTR) and endoscopic (ECTR) techniques widely used. As surgical practices evolve and outpatient care expands, understanding future utilization trends across care settings is increasingly important. This study projects the use of OCTR and ECTR through 2040 to inform shifting surgical preferences and healthcare demands. Methods This study analyzed procedural data from 2010 to 2019 using the PearlDiver Mariner all-payer claims database. Cases of OCTR and ECTR were identified using Current Procedural Terminology codes. Procedures were further stratified by inpatient or outpatient status based on the documented site of service field within the database. Log-linear, Poisson, negative binomial regression, and autoregressive integrated moving average (ARIMA) models were applied to procedural volumes to project trends through 2040. The ARIMA model was selected based on the lowest normalized root mean square error and overall model performance. Results In 2019, there were 31,190 outpatient ECTR, 155 inpatient ECTR, 101,334 outpatient OCTR, and 1359 inpatient OCTR procedures. By 2040, outpatient ECTR is projected to grow to 65,072 cases (95% CI, 62,471–67,781) at 3.79% annually. Inpatient ECTR is projected to reach 181 cases (95% CI, 97–340) with 2.13% annual growth. Outpatient OCTR is expected to decline to 77,834 cases (95% CI, 76,287–79,413), and inpatient OCTR to 962 cases (95% CI, 809–1143), with annual decreases of 1.19% and 1.48%, respectively. Conclusions By 2040, demand for outpatient ECTR is projected to increase by 110.31% compared to 2019, whereas outpatient OCTR is expected to decline by 20.31%. Although inpatient utilization remains limited, the adoption of endoscopic techniques is anticipated to rise across all care settings, in contrast to the continued decline of open procedures. These trends highlight the ongoing shift toward minimally invasive, ambulatory surgical care. Strategic planning in surgical training, healthcare infrastructure, and reimbursement models will be critical to meet changing demands. Further research is needed to validate these projections in broader populations and across diverse healthcare systems.

Background: Glucagon-like peptide-1 receptor agonists (GLP-1) are approved for type 2 diabetes treatment. Given the link between diabetes-associated metabolic inflammation and increased carpal tunnel syndrome (CTS) risk, the aim of this study was to investigate development of CTS in diabetic patients who both were and were not taking GLP-1 therapy using a large claims database. Methods: A retrospective cohort study used a national claims database to identify diabetic patients. Those prescribed GLP-1 therapy were matched to controls by age, sex, comorbidity index, tobacco use, and obesity. Multivariable logistic regression evaluated the 2-year CTS incidence, controlling for various health conditions and socioeconomic factors. Secondary analysis also evaluated the rate of carpal tunnel release (CTR) after being diagnosed with CTS. Results: Glucagon-like peptide-1 therapy significantly reduced 2-year CTS diagnosis risk (odds ratio [OR] 0.49; 95% confidence interval [CI] 0.46-0.52; P < .001). Independent risk factors for increased CTS incidence included chronic obstructive pulmonary disease, osteoarthritis, coronary artery disease, depression, hypothyroidism, and rheumatoid arthritis (RA). Of patients who developed CTS, GLP-1 therapy was associated with increased odds of undergoing CTR (OR 1.23; 95% CI: 1.08-1.41; P = .002). Conclusions: Glucagon-like peptide-1 therapy is associated with decreased CTS risk in diabetic patients—potentially due to improved metabolic health—and increased odds of undergoing CTR once diagnosed. Further research is needed to clarify GLP-1 therapy’s role in reducing nervous system and musculoskeletal disease burden.

Background: Diabetic patients experience carpal tunnel syndrome (CTS) at high rates, have increased symptom severity, and experience prolonged recovery after carpal tunnel release (CTR). This study assessed the association of glucagon-like peptide-1 receptor agonist (GLP-1) therapy with postoperative outcomes after CTR in type II diabetic patients with CTS. Methods: Using the PearlDiver database, 25 229 diabetic patients with CTS who underwent CTR and were prescribed GLP-1 therapy were identified and exact matched to 25 229 controls based on age, sex, Elixhauser comorbidity index, tobacco use, obesity, hypothyroidism, and body mass index where available. Demographic variables and comorbidities were compared between groups using Kruskal-Wallis analyses for continuous variables and chi-square tests for categorical variables. Bivariate logistic regression analysis was conducted for 90-day outcomes and 2-year CTR revision. Results: Patients on GLP-1 therapy had decreased risk of 90-day medical complications (odds ratio [OR] = 0.90; 95% confidence interval [CI], 0.84-0.96) and hospital readmission (OR = 0.85; 95% CI, 0.77-0.94) of 0.5% and 0.4%, respectively, compared with controls. No significant differences were found in 90-day surgical complications or 2-year revision rates between cohorts. There were no cases of aspiration pneumonia. The GLP-1 cohort had increased odds of higher 90-day total costs of care (OR = 2.42; 95% CI, 1.88-3.15). Conclusions: GLP-1 therapy is associated with reduced risk of 90-day medical complications and hospital readmission following CTR in diabetic patients, suggesting these medications may optimize comorbidity profiles via glucose control preoperatively. Future studies may examine whether GLP-1 therapy is associated with minimum clinically important difference in patient-reported outcome measures for CTS in diabetic patients.

Background: Carpal Tunnel Syndrome (CTS) is associated with a significant personal and societal burden. Evaluating access to care can identify barriers, limitations, and disparities in the delivery of healthcare services in this population. The purpose of this study was to evaluate access to overall healthcare and healthcare utilization among patients with CTS. Methods: This is a retrospective cohort study conducted with the All of Us database. Patients diagnosed with CTS that completed the access to care survey were included and matched to a control group. The primary outcomes were access to care across 4 domains: (1) delayed care, (2) could not afford care, (3) skipped medications, and (4) over 1 year since seeing provider. Secondary analysis was then performed to identify patient-specific factors associated with reduced access to care. Results: In total, 7649 patients with CTS were included and control matched to 7649 patients without CTS. In the CTS group, 33.7% (n = 2577) had delayed care, 30.4% (n = 2323) could not afford care, 15.4% (n = 1180) skipped medications, and 1.6% (n = 123) had not seen a provider in more than 1 year. Within the CTS cohort, low-income, worse physical health, and worse mental health were associated with poor access to care. Conclusion: Patients experience notable challenges with delayed care, affordability of care, and medication adherence regardless of having a diagnosis of CTS. Targeted interventions on modifiable risk factors such as low income, poor mental health, and poor physical health are important opportunities to improve access to care in this population.
