Non-Tobacco Nicotine dependence associated with increased Postoperative Complications following Intramedullary Nailing for Intertrochanteric Femur Fractures.

Objectives: Nicotine usage is known to increase postoperative complications; however, studies show that the general population believes that non-tobacco nicotine delivery devices are a safer option compared to tobacco-based nicotine products. This study evaluates postoperative complications between non-tobacco nicotine dependent and non-nicotine dependent patients for intramedullary nailing in intertrochanteric femur fractures. Methods: Utilizing the TriNetX database, we retrospectively examined postoperative outcomes in patients aged 18 to 90 who underwent intramedullary nailing for intertrochanteric femur fractures between November 21, 2013, and November 21, 2023. Two cohorts were analyzed: Cohort A comprised nicotine-dependent patients without tobacco product usage (e.g. cigarettes or chewing tobacco) and Cohort B consisted of patients without any nicotine dependence. Propensity matching was performed for BMI, type 2 diabetes, alcohol/substance abuse, socioeconomic status, and demographic factors. Outcomes assessed included mortality, sepsis, pneumonia, revision, dehiscence, pulmonary embolism, nonunion, and deep vein thrombosis within 1 day to 6 months post-treatment. Results: A total of 2,041 non-tobacco nicotine dependent patients were matched with 22,872 non-nicotine dependent patients. Non-tobacco nicotine dependent patients experienced higher associated risk for numerous postoperative complications compared to non-nicotine dependent patients including increased risk for mortality within 6 months postoperatively (RR 1.386, 10.7% vs 7.7%, P = 0.001), sepsis (RR 1.459, 4.4% vs 3.0%, P = 0.027), and pneumonia (RR 1.751, 5.8% vs 3.3%, P = 0.001). Conclusions: Non-tobacco nicotine dependence increases postoperative complications for patients undergoing intramedullary nailing for intertrochanteric femur fractures. Our findings support the need for development of perioperative nicotine cessation guidelines for non-tobacco nicotine users. Level of evidence: Level III, Prognostic.

Non-Tobacco Nicotine Dependence and Rates of Postoperative Complications in Total Knee Arthroplasty: A Propensity-Matched Comparison.

INTRODUCTION: Tobacco use elevates the incidence of postoperative complications and remains a key modifiable risk factor of perioperative surgical optimization. It remains unclear whether non-tobacco nicotine dependence confers an increased risk of surgical complications. This study evaluates postoperative complications in patients with non-tobacco nicotine dependence for total knee arthroplasty (TKA). METHODS: We queried the TriNetX health database using Current Procedural Terminology and International Classification of Diseases, 10th Revision (ICD-10) codes and identified two cohorts for evaluation. Cohort A was defined as patients who had a TKA; had a dependence on nicotine; did not have nicotine dependence to cigarettes, chewing tobacco, other tobacco products; and were between the ages of 35 and 90 years. Cohort B was defined as patients who had a TKA but did not have a dependence on nicotine or a personal history of nicotine dependence and were between the ages of 35 and 90 years. RESULTS: This study analyzed a total of 10,594 non-tobacco nicotine-dependent patients and 175,079 non-dependent patients who underwent TKA. In the analysis of propensity-matched cohorts, non-tobacco nicotine-dependent patients demonstrated an increased rate of various postoperative complications within 90 days. Dependent patients saw a significantly increased risk of infection after a procedure (P < 0.001), deep vein thrombosis (P < 0.001), pulmonary embolism (P < 0.001), sepsis (P = 0.0065), and prosthetic joint infection (P = 0.0361) and a higher 3-year revision rate (P = 0.0084). DISCUSSION: Non-tobacco nicotine dependence demonstrated an increased associated risk of postoperative surgical complications for patients undergoing TKA. Orthopaedic surgeons should consider evaluating non-tobacco nicotine dependence within their surgical optimization protocol. LEVEL OF EVIDENCE: Level III, Prognostic.

Risk of Suicide and Self-Harm Following Gender-Affirmation Surgery.

Introduction With the growing acceptance of transgender individuals, the number of gender affirmation surgeries has increased. Transgender individuals face elevated depression rates, leading to an increase in suicide ideation and attempts. This study evaluates the risk of suicide or self-harm associated with gender affirmation procedures. Methods This retrospective study utilized de-identified patient data from the TriNetX (TriNetX, LLC, Cambridge, MA) database, involving 56 United States healthcare organizations and over 90 million patients. The study involved four cohorts: cohort A, adults aged 18-60 who had gender-affirming surgery and an emergency visit (N = 1,501); cohort B, control group of adults with emergency visits but no gender-affirming surgery (N = 15,608,363); and cohort C, control group of adults with emergency visits, tubal ligation or vasectomy, but no gender-affirming surgery (N = 142,093). Propensity matching was applied to cohorts A and C. Data from February 4, 2003, to February 4, 2023, were analyzed to examine suicide attempts, death, self-harm, and post-traumatic stress disorder (PTSD) within five years of the index event. A secondary analysis involving a control group with pharyngitis, referred to as cohort D, was conducted to validate the results from cohort C. Results Individuals who underwent gender-affirming surgery had a 12.12-fold higher suicide attempt risk than those who did not (3.47% vs. 0.29%, RR 95% CI 9.20-15.96, p < 0.0001). Compared to the tubal ligation/vasectomy controls, the risk was 5.03-fold higher before propensity matching and remained significant at 4.71-fold after matching (3.50% vs. 0.74%, RR 95% CI 2.46-9.024, p < 0.0001) for the gender affirmation patients with similar results with the pharyngitis controls. Conclusion Gender-affirming surgery is significantly associated with elevated suicide attempt risks, underlining the necessity for comprehensive post-procedure psychiatric support.

Superior labrum anterior to posterior (SLAP) repair is associated with increased rate of subsequent rotator cuff diagnoses and revision surgery: a propensity-matched comparison.

BACKGROUND: Surgical management of superior labral anterior to posterior (SLAP) tears remains controversial. Current management utilizes 2 well-established procedures: biceps tenodesis and SLAP repair. This study evaluates the complications associated with arthroscopic SLAP repair vs. an open or arthroscopic biceps tenodesis to further elucidate optimal surgical management. METHODS: In this retrospective cohort study, the TriNetX database was utilized to evaluate patients who underwent repair of SLAP lesions (International Classification of Diseases, Tenth Revision code: S43.43) from May 15, 2003, to May 15, 2023. Three patient cohorts were evaluated: those who underwent arthroscopic SLAP repair (Current Procedural Terminology [CPT] code: 29807), those who underwent arthroscopic biceps tenodesis (CPT code: 29828), and those who underwent open tenodesis of the biceps (CPT code: 23430). Cohorts were propensity matched for type 2 diabetes, nicotine dependence, alcohol-related disorders, body mass index, and demographic factors such as age at event, ethnicity, race, and sex. The outcomes evaluated were disruption of surgical wound, deep vein thrombosis, mononeuropathy of upper limb, shoulder contusion, humeral fracture, sepsis, deceased, acute postoperative pain, revision, shoulder stiffness, and rotator cuff strain. All outcomes were evaluated within 1 year postprocedure. RESULTS: A total of 11,081 arthroscopic SLAP repairs, 9960 arthroscopic biceps tenodesis, and 9420 open biceps tenodesis were matched. Compared with patients who underwent arthroscopic biceps tenodesis, those who underwent arthroscopic SLAP repair were 1.8 times more likely to undergo revision (2.9% vs. 1.6%, P < .0001). Compared with those who underwent open biceps tenodesis, patients who had SLAP repair performed were 1.4 times more likely to undergo revision (3.1% vs. 2.3%, P = .013) and 1.6 times more likely to have a subsequent rotator cuff strain diagnosis (5.1% vs. 3.2%, P = .0002). Compared with patients who underwent SLAP repair, those who underwent arthroscopic biceps tenodesis exhibited 1.3 times more instances of acute postoperative pain (5.2% vs. 4.0%, P = .011). Similarly, open biceps tenodesis exhibited 1.8 times more instances of acute postoperative pain (6.9% vs. 3.8%, P < .0001) and 1.3 times more shoulder stiffness (11.8% vs. 9.0%, P < .0001). CONCLUSION: In the last 20 years, patients who underwent SLAP repair were associated with higher risk of revision surgery and subsequent rotator cuff strain diagnosis. Conversely, patients who underwent biceps tenodesis were associated with higher rates of acute postoperative pain and shoulder stiffness.

Phenytoin is associated with increased risk of osteoporosis and fragility fractures in adult epileptic patients.

INTRODUCTION: Osteoporotic fractures lead to significant decreases in the quality of life with increases in morbidity, mortality, and disability. Treatment with a variety of anti-epileptic drugs, such as phenytoin, has been understood to cause a decrease in bone mineral density. MATERIALS AND METHODS: Cohort A was identified as patients that were 18-55 years old that had epilepsy and recurrent seizures that were also prescribed phenytoin. Cohort B was identified as patients that were 18-55 years old that had epilepsy and recurrent seizures but were not prescribed phenytoin or other anti-epileptic medications. Cohorts were matched for relevant confounding pathologies and demographic factors. Outcomes were evaluated from 1 day to 5 years after the indexed event. RESULTS: A total of 35,936 patients with epilepsy that were prescribed phenytoin were matched with 109,335 patients with epilepsy that were not prescribed phenytoin. Patients on phenytoin therapy were at significantly higher risk for osteoporosis without pathological fracture, fracture of metatarsal bone, fracture of shoulder and upper arm, fracture of distal radius, fracture of thoracic vertebra, fracture of cervical vertebra, fracture of lumbar vertebra, fracture of femoral head or neck, pertrochanteric fracture, femoral shaft fracture, and distal tibia fracture (all outcomes p < 0.001). CONCLUSION: Epileptic patients on phenytoin therapy that were 18-55 years old exhibited higher associated risk of osteoporosis and osteoporotic-fragility fractures of various regions. Patients that undergo phenytoin therapy for epilepsy treatment should be educated on the increased risk of bone fractures and have appropriate lifestyle and diet modifications.

Quality and Readability Analysis of Online Information on First Metatarsophalangeal Joint Fusion.

Patients frequently turn to the internet to learn about their orthopedic procedures. This study evaluates the readability and quality of first metatarsophalangeal (MTP) joint fusion information found online. We evaluated websites based on classification, search term, readability, HON code, DISCERN score, Journal of the American Medical Association benchmark criteria, and an author-created MTP fusion index (MFI). The average readability of websites was 8.48 ± 1.99, above the recommended sixth- or eighth-grade reading level. Almost half of all websites (48.98%) provided "poor" information. Keywords had no significant impact on the readability or quality of information. Academic/governmental websites had the highest quality of information, with the highest DISCERN and second highest MFI. Most websites (52.04%) were commercial and were the easiest to read, but had the second lowest DISCERN and MFI scores. Our results suggest that inappropriate information on the MTP joint fusion procedure is abundant online. Academic/governmental websites have the highest quality of information, but may be difficult for patients to comprehend. Many websites do have readable and relevant information. We recommend that physicians create a list of websites with accurate, relevant information for patients to circumvent the misinformation they may find while navigating and reading online.

Nicotine Dependence and Rates of Postoperative Complications in Achilles Tendon Repair.

BACKGROUND: Nicotine is a modifiable risk factor that is well demonstrated to cause deleterious effects on tendon healing and overall health. Individuals that have a dependence on nicotine may be at an elevated risk for numerous postoperative complications when compared to nondependent patients. The purpose of this study is to evaluate the complications postoperatively between nicotine- and non-nicotine-dependent Achilles tendon repairs. METHODS: The global health network database, TriNetX, was used to access and analyze deidentified patient information. Two cohorts were identified for the purposes of this study. Cohort A was defined as patients who had an Achilles tendon repair (Current Procedural Terminology [CPT]: 27650 or CPT: 27654) and had a dependence to nicotine (International Classification of Diseases, Tenth Revision, code: F17). Cohort B was defined as patients who had an Achilles tendon repair but did not have a dependence to nicotine. Data were gathered from health care organizations from August 21, 2000, to August 21, 2023. All postoperative complications were analyzed between 1 and 90 days after the Achilles tendon repair. RESULTS: A total of 2117 nicotine-dependent patients were matched with 18 102 non-nicotine-dependent patients. After propensity matching for age at event, ethnicity, race, sex, and type 2 diabetes mellitus, nicotine-dependent patients who underwent Achilles tendon repair experienced higher associated risk for numerous postoperative complications. When compared to nondependent patients, nicotine-dependent patients had increased risk for wound disruption (risk ratio [RR] 1.55, 95% CI 1.11-2.16) and infection following a procedure (RR 1.64, 95% CI 1.09-2.47) within 90 days post Achilles tendon repair. CONCLUSION: In this database study using propensity matching, nicotine-dependent patients who underwent Achilles tendon repair were correlated with an increased associated risk for wound disruption and infection after a procedure than their non-nicotine-dependent counterpart. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
