Regional variation in low-value musculoskeletal surgery: a nationwide study from the Finnish Care Register.

BACKGROUND AND PURPOSE:  Healthcare systems globally are grappling with resource constraints and rising costs. Concerns have been raised about "low-value" care, which consumes healthcare resources without benefiting patients. We aimed to examine regional differences in common low-value musculoskeletal surgeries in Finland and explore explanatory factors behind the variation. METHODS:  Using data from the Finnish Care Register for Health Care, surgeries conducted from 2006-2007 compared with 2020-2021 were analyzed across 20 hospital districts. Selected surgeries (acromioplasty, rotator cuff repair, partial meniscectomy, wrist arthroscopy, ankle arthroscopy, and distal radius fracture fixation) were categorized based on NOMESCO procedure codes, and incidence rates in older populations were calculated based on population size derived from Statistics Finland. RESULTS:  We found substantial regional disparities in low-value surgeries. The incidence rates were higher in hospitals with high historical incidence rates and smaller population sizes, suggesting that the uptake of evidence is slower in small non-academic hospitals. CONCLUSION:  The incidence of low-value surgery is declining but regional differences remain large. It is unlikely that regional variation in disease incidence explains such large variation in low-value surgery. Instead, local treatment culture seems to be the driving force behind low-value surgery, and the practices seem to be more entrenched in small hospitals.

Soft bandage, splint or cast as the treatment of distal forearm torus fracture in children: a systematic review and meta-analysis.

A meta-analysis including all relevant randomized controlled trials was conducted to compare soft bandage, splint and cast as the treatment of torus fracture. PubMed, Scopus, and Web of Science databases were searched in January 2023. Two comparisons were made: (1) splint versus cast, and (2) bandage versus rigid immobilization (i.e. splint or cast). Main outcomes were pain, clinical healing of the fracture and return to activities. Secondary outcomes were adverse events (skin issues, problems with cast/splint/bandage) and patient/parental satisfaction. Seven studies with 1550 patients were included. Splint was associated with higher pain scores at 3 days compared to cast (Mean difference [MD] 1.00, CI 0.06-1.94) and at 1 week (MD 1.46, CI 0.84-2.08, moderate-certainty evidence), but faster return to activities (at 3 weeks RR 1.77, CI 1.09-2.88, at 4 weeks RR 1.44, CI 1.11-1.82, moderate-certainty evidence). All torus fractures heal clinically within 3-4 weeks (low-certainty evidence). Bandage may lead to slightly higher pain score (MD 0.35, CI 0.04-0.66, moderate-certainty evidence) at first day after treatment compared to rigid immobilization, but no evidence of a difference was found in later time points. In conclusion, soft bandage or removable wrist splint seem to be optimal first-line treatment of distal forearm torus fracture.

Choice of Bearings Influences the Implant Survival of Total Hip Arthroplasty in Patients Who Have Osteoarthritis Aged 55 Years or More: Results of 158,044 Patients From the Nordic Arthroplasty Register Association From 2005 to 2017.

BACKGROUND: The aim of our study was to compare implant survival rates of different total hip arthroplasty (THA) bearings in the Nordic Arthroplasty Register Association. METHODS: All conventional primary THAs performed between 2005 and 2017 in patients aged more than 55 years who had primary osteoarthritis were studied. Metal-on-highly cross-linked polyethylene (MoXLP), ceramic-on-highly cross-linked polyethylene (CoXLP), ceramic-on-ceramic (CoC), and metal-on-metal (MoM) bearings were included. The outcome was a revision. Kaplan-Meier (KM) estimates were calculated at 5 and 10 years. The risk for revision was analyzed using a flexible parametric survival model adjusted for nation, age, sex, femoral head size, and femoral fixation. RESULTS: A total of 158,044 THAs were included. The 5-year KM estimates were 95.9% (95% confidence interval [CI] 95.8 to 96.1) in MoXLP, 95.8% (95% CI 95.6 to 96.1) in CoXLP, 96.7% (95% CI 96.4 to 97.0) in CoC, and 93.9% (95% CI 93.5 to 94.4) in MoM. The 10-years KM estimates were 94.2% (94.0 to 94.5) in MoXLP, 94.3% (93.9 to 94.8) in CoXLP, 95.4% (95.0 to 95.9) in CoC, and 85.5% (84.9 to 86.2) in MoM. Compared with MoXLP, the adjusted risk for revision was lower in CoC (hazard ratio [HR] 0.6, CI 0.5 to 0.6), similar in CoXLP (HR 1.0, CI 0.9 to 1.0), and higher in MoM (HR 1.3, CI 1.2 to 1.4). CONCLUSIONS: We found that MoXLP, CoXLP, and CoC bearings evinced comparably high implant survival rates up to 10 years, and they can all be regarded as safe options in this patient group. The MoM bearings were associated with clearly lower survivorship. The CoC bearings had the highest implant survival and a lower adjusted risk for revision compared with highly cross-linked polyethylene bearings.

The Influence of Adolescent health-related Behaviors on Degenerative Low Back Pain Hospitalizations and Surgeries in Adulthood: A Longitudinal Study.

STUDY DESIGN: Retrospective longitudinal study. OBJECTIVE: This study aims to investigate the influence of adolescent health-related behaviors (physical activity, high BMI, drunkenness, smoking), self-reported chronic disease, and low socioeconomic status (SES) on the development of low back pain requiring hospitalization or surgery. SUMMARY OF BACKGROUND DATA: The baseline data were surveys gathered biennially in 1981-1997 (the Adolescent Health and Lifestyle Survey) and individually linked with outcome data, degenerative low back pain hospitalizations, and spine surgeries retrieved from the Care Register for Health Care. A total of 47 724 participants were included. Explanatory variables included physical activity, high BMI, smoking, monthly drunkenness, chronic diseases, and family SES. METHODS: A logistic regression model was used to analyze the influence of adolescent health-related behaviors (physical activity, high BMI, drunkenness, smoking), self-reported chronic disease, and low socioeconomic status (SES) on degenerative low back pain hospitalization, lumbar disc herniation (LDH) hospitalization and/or spine surgery. Covariates were selected using directed acyclic graphs (DAGs). RESULTS: A total of 5538 participants had degenerative low back pain hospitalizations, 2104 had LDH hospitalizations, and 913 had spinal surgery over an average of 27-years follow-up. High BMI (aOR 1.25, CI 1.12-1.38), smoking (aOR 1.53, CI 1.43-1.62), monthly drunkenness (aOR 1.17, CI 1.10-1.26), and chronic diseases (aOR 1.47, CI 1.35-1.61) in adolescence increased the odds of hospitalizations during follow-up. In addition, high BMI (aOR 1.37, CI 1.09-1.72), smoking (aOR 1.40, CI 1.21-1.61), and monthly drunkenness (aOR 1.19, CI 1.01-1.39) increased the odds of spine surgeries. CONCLUSIONS: We found that smoking, high BMI, monthly drunkenness, chronic diseases, and low family SES in adolescence increased the likelihood of degenerative low back pain hospitalizations in adulthood. In addition, high BMI, smoking, and monthly drunkenness in adolescence increased the odds of spinal surgeries.

Paediatric traumatic brain injury and attention-deficit/hyperactivity disorder medication in Finland: a nationwide register-based cohort study.

BACKGROUND: The association between paediatric traumatic brain injury (pTBI) and post-traumatic attention-deficit/hyperactivity disorder (ADHD) medication usage remains understudied subject. OBJECTIVE: We aimed to evaluate the association between pTBI and subsequent ADHD medication. METHODS: A nationwide retrospective cohort study in Finland from 1998 to 2018 included 66 594 patients with pTBI and 61 412 references with distal extremity fractures. ADHD medication data were obtained from the Finnish Social Insurance Institution. The primary outcome was post-traumatic pediatric ADHD medication. A 1-year washout period was applied, and follow-up started 1 year post-pTBI. FINDINGS: Kaplan-Meier analyses showed higher ADHD medication usage in patients with pTBI, especially post-operatively. Both sex groups exhibited elevated rates compared with the reference group. Over 10 years, cumulative incidence rates were 3.89% (pTBI) vs 1.90% (reference). HR for pTBI was 1.89 (95% CI 1.70 to 2.10) after 4 years and 6.31 (95% CI 2.80 to 14.20) for the operative group after the initial follow-up year. After 10 years, cumulative incidence in females increased to 2.14% (pTBI) vs 1.07% (reference), and in males, to 5.02% (pTBI) vs 2.35% (reference). HR for pTBI was 2.01 (95% CI 1.72 to 2.35) in females and 2.23 (95% CI 2.04 to 2.45) in males over 1-20 years. CONCLUSIONS: A substantial association between pTBI and post-traumatic ADHD medication was evidenced over a 20-year follow-up period. CLINICAL IMPLICATIONS: These results stress the need for preventive measures for pTBI and highlight the potential impact of long-term post-traumatic monitoring and psychoeducation.

Fear of Childbirth After Major Orthopedic Traumas: A Nationwide Multi-Register Analysis.

BACKGROUND: The aim of this study was to evaluate the association between previous major traumas and the prevalence of fear of childbirth (FOC) and the subsequent effects of FOC on the intended mode of delivery. METHODS: In this nationwide retrospective register-based cohort study, data from the Care Register for Health Care were linked with the National Medical Birth Register (MBR) to evaluate the prevalence of FOC after major traumas. A total of 18,573 pregnancies met the inclusion criteria. A multivariable logistic regression model was used to assess the effects of FOC on the intended mode of delivery. Women with major traumas before pregnancy were compared to individuals with wrist fractures. Adjusted odds ratios (aORs) with 95% CIs between the groups were compared. RESULTS: Of those pregnancies that occurred after major traumas, 785 (6.2%) women were diagnosed with FOC after traumatic brain injury (TBI), 111 (6.1%) women after spine fracture, 38 (5.0%) women after pelvic fracture, 22 (3.2%) women after hip or thigh fracture, and 399 (5.2%) women in the control group. Among those women diagnosed with FOC, the adjusted odds for elective CB as an intended mode of delivery were highest among women with previous spine fractures (aOR 2.28, CI 1.45-3.60) when compared to the control group. CONCLUSIONS: We found no evidence of differences in maternal FOC in patients with preceding major traumas when compared to the control group. Therefore, it seems highly likely that the major trauma itself is the explanatory factor for the increased rate of elective CB.

Early Predictors of Recovery From Nonoperatively Treated Achilles Tendon Rupture: 1 Year Follow-Up Study.

PURPOSE: To investigate early structural and mechanical predictors of plantarflexor muscle strength and the magnitude of Achilles tendon (AT) nonuniform displacement at 6 and 12 months after AT rupture. METHODS: Thirty-five participants (28 males and 7 females; mean ± SD age 41.7 ± 11.1 years) were assessed for isometric plantarflexion maximal voluntary contraction (MVC) and AT nonuniformity at 6 and 12 months after rupture. Structural and mechanical AT and plantarflexor muscle properties were measured at 2 months. Limb asymmetry index (LSI) was calculated for all variables. Multiple linear regression was used with the 6 and 12 month MVC LSI and 12 month AT nonuniformity LSI as dependent variables and AT and plantarflexor muscle properties at 2 months as independent variables. The level of pre- and post-injury sports participation was inquired using Tegner score at 2 and 12 months (scale 0-10, 10 = best possible score). Subjective perception of recovery was assessed with Achilles tendon total rupture score (ATRS) at 12 months (scale 0-100, 100=best possible score). RESULTS: Achilles tendon resting angle (ATRA) symmetry at 2 months predicted MVC symmetry at 6 and 12 months after rupture (ß = 2.530, 95% CI 1.041-4.018, adjusted R2 = 0.416, p = 0.002; ß = 1.659, 95% CI 0.330-2.988, adjusted R2 = 0.418, p = 0.016, respectively). At 12 months, participants had recovered their pre-injury level of sports participation (Tegner 6 ± 2 points). The median (IQR) ATRS score was 92 (7) points at 12 months. CONCLUSION: Greater asymmetry of ATRA in the early recovery phase may be a predictor of plantarflexor muscle strength deficits up to 1 year after rupture. TRIAL REGISTRATION: This research is a part of "nonoperative treatment of Achilles tendon rupture in Central Finland: a prospective cohort study" that has been registered in ClinicalTrials.gov (NCT03704532).

Injury incidence in golf-a systematic review and meta-analysis.

OBJECTIVE: There is a lack of comprehensive analysis of injuries in golf per exposure time. Thus, the aim was to report the pooled incidence of injuries in golf. METHODS: We searched PubMed, Scopus, SPORTDiscus, and Web of Science databases in March 2024 for this systematic review and meta-analysis. We included observational studies reporting the number of injuries per exposure time. A random-effects model was used to calculate the pooled injury incidence per 1000 athlete exposures (18 holes of golf) with 95% confidence intervals (CI). Incidences were separately analyzed for men, women, amateurs, professionals, and special athletes. RESULTS: A total of 999 studies were screened, 29 full texts were assessed, and 7 studies with 269,754 athlete exposures were included. Seven studies assessed the overall incidence of injury, and the pooled estimate was 2.5 per 1000 athlete exposures (CI 0.9-7.5). The incidence was higher in special athletes (21.0, CI 7.7-45.1; one study) than among professionals (8.5, CI 7.6-9.4; one study), or in amateurs (1.3, CI 0.5-4.0; five studies). The injury incidence was 2.6 per 1000 athlete exposures (CI 0.7-9.6; four studies) in women and 1.4 per 1000 athlete exposures (CI 0.4-5.2; three studies) in men. A sensitivity analysis without special athletes had an incidence of 1.9 (CI 0.7-4.9; six studies). CONCLUSION: The injury incidence in golf is 2.5 injuries per 1000 athlete exposures (18 holes of golf). Reporting was limited as only one study reported injuries per exposure time in professionals, and in total, only seven studies were found. More research is needed in all levels and age groups to better estimate the injury incidence and associated risk factors in golf.

Preventive medication efficacy after 1-year follow-up for graft failure in coronary artery bypass surgery patients: Bayesian network meta-analysis.

To compare preventive medications against graft failures in coronary artery bypass graft surgery (CABG) patients after a 1-year follow-up. Systematic review with Bayesian network meta-analysis and meta-regression analysis. We searched PubMed, Scopus, and Web of Science databases in February 2023 for randomized controlled trials, comparing preventive medications against graft failure in CABG patients. We included studies that reported outcomes at 1 year after surgery. Our primary outcome was graft failure After screening 11,898 studies, a total of 18 randomized trials were included. Acetylsalicylic acid (ASA) [odds ratios (OR) 0.51, 95% credibility interval (CrI) 0.28-0.95, meta-regression OR 0.54, 95% CrI 0.26-1.00], Clopidogrel + ASA (OR 0.27, 95% CrI 0.09-0.76, meta-regression OR 0.28, 95% CrI 0.09-0.85), dipyridamole + ASA (OR 0.50, 95% CrI 0.30-0.83, meta-regression OR 0.49, 95% CrI 0.26-0.90), ticagrelor (OR 0.40, 95% CrI 0.16-1.00, meta-regression OR 0.43, 95% CrI 0.15-1.2), and ticagrelor + ASA (OR 0.26, 95% CrI 0.10-0.62, meta-regression OR 0.28, 95% CrI 0.10-0.68) were superior to placebo in preventing graft failure. Rank probabilities suggested the highest likelihood to be the most efficacious for ticagrelor + ASA [surface under the cumulative ranking (SUCRA) 0.859] and clopidogrel + ASA (SUCRA 0.819). The 95% CrIs of ORs for mortality, bleeding, and major adverse cardio- and cerebrovascular events (MACE) were wide. A trend towards increased bleeding risk and decreased MACE risk was observed when any of the medication regimens were used when compared to placebo. Sensitivity analysis excluding studies with a high risk of bias yielded equivalent results. Of the reviewed medication regimens, dual antiplatelet therapy combining ASA with ticagrelor or clopidogrel was found to result in the lowest rate of graft failures.

Antithrombotic management after aortic valve replacement with biological prosthesis: a meta-analysis.

BACKGROUND: We aimed to summarise the existing knowledge regarding antithrombotic medications following surgical aortic valve replacement (SAVR) using a biological valve prosthesis. METHODS: We performed a meta-analysis of studies that reported the results of using antithrombotic medication to prevent thromboembolic events after SAVR using a biological aortic valve prosthesis and recorded the outcomes 12 months after surgery. Since no randomised controlled trials were identified, observational studies were included. The analyses were conducted separately for periods of 0-12 months and 3-12 months after surgery. A random effects model was used to calculate pooled outcome event rates and 95% confidence intervals (CIs). RESULTS: The search yielded eight eligible observational studies covering 6727 patients overall. The lowest 0- to 12-month mortality was observed in patients with anticoagulation (2.0%, 95% CI 0.4-9.7%) and anticoagulation combined with antiplatelet therapy (2.2%, 95% CI 0.9-5.5%), and the highest was in patients without antithrombotic medication (7.3%, 95% CI 3.6-14.2%). Three months after surgery, mortality was lower in anticoagulant patients (0.5%, 95% CI 0.1-2.6%) than in antiplatelet patients (3.0%, 95% CI 1.2-7.4%) and those without antithrombotics (3.5%, 95% CI 1.3-9.3%). There was no eligible evidence of differences in stroke rates observed among medication strategies. At 0- to 12-month follow-up, all antithrombotic treatment regimens resulted in an increased bleeding rate (antiplatelet 4.2%, 95% CI 2.9-6.1%; anticoagulation 7.5%, 95% CI 3.8-14.4%; anticoagulation combined with antiplatelet therapy 8.3%, 95% CI 5.7-11.8%) compared to no antithrombotic medication (1.1%, 95% CI 0.4-3.4%). At 3- to 12-month follow-up, there was up to an eight-fold increase in the bleeding rate in patients with anticoagulation combined with antiplatelet therapy when compared to those with no antithrombotic medication. Overall, the evidence certainty was ranked as very low. CONCLUSION: Although this meta-analysis reveals that anticoagulation therapy has a beneficial tendency in terms of mortality at 1 year after biological SAVR and suggests potential advantages in continuing anticoagulation beyond 3 months, it is limited by very low evidence certainty. The imperative for cautious interpretation and the urgent need for more robust randomised research underscore the complexity of determining optimal antithrombotic strategies in this patient population.

Total joint arthroplasty for thumb carpometacarpal joint osteoarthritis: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND PURPOSE: Thumb carpometacarpal (CMC) joint osteoarthritis (OA) is increasingly treated with total joint arthroplasty (TJA). We aimed to perform a systematic review and meta-analysis of the benefits and harms of the TJA for thumb CMC OA compared with other treatment strategies. PATIENTS AND METHODS: We performed a systematic search on MEDLINE and CENTRAL databases on August 2, 2023. We included randomized controlled trials investigating the effect of TJA in people with thumb CMC joint OA regardless of the stage or etiology of the disease or comparator. The outcomes were pooled with a random effect meta-analysis. RESULTS: We identified 4 studies randomizing 420 participants to TJA or trapeziectomy. At 3 months, TJA's benefits for pain may exceed the clinically important difference. However, after 1-year follow-up TJA does not improve pain compared with trapeziectomy (mean difference 0.53 points on a 0 to 10 scale; 95% confidence interval [CI] 0.26-0.81). Furthermore, it provides a transient benefit in hand function at 3 months (measured with Disabilities of Arm, Shoulder, and Hand questionnaire, scale 0-100, lower is better) compared with trapeziectomy with or without ligament reconstruction tendon interposition. The benefit in function diminished to a clinically unimportant level at 1-year follow-up (4.4 points better; CI 0.42-8.4). CONCLUSION: Transient benefit in hand function for TJA implies that it could be a preferable option over trapeziectomy for people who consider fast postoperative recovery important. However, current evidence fails to inform us if TJA carries long-term higher risks of revisions compared with trapeziectomy.

Impact of childhood traumatic brain injury on fitness for service class, length of service period, and cognitive performance during military service in Finland from 1998 to 2018: A retrospective register-based nationwide cohort study.

INTRODUCTION: Traumatic brain injury (TBI) can cause neuronal damage and cerebrovascular dysfunction, leading to acute brain dysfunction and considerable physical and mental impairment long after initial injury. Our goal was to assess the impact of pediatric TBI (pTBI) on military service, completed by 65-70% of men in Finland. METHODS: We conducted a retrospective register-based nationwide cohort study. All patients aged 0 to 17 years at the time of TBI, between 1998 and 2018, were included. Operatively and conservatively treated patients with pTBI were analyzed separately. The reference group was comprised of individuals with upper and lower extremity fractures. Information on length of service time, service completion, fitness for service class, and cognitive performance in a basic cognitive test (b-test) was gathered from the Finnish Military Records for both groups. Linear and logistic regression with 95% CI were used in comparisons. RESULTS: Our study group comprised 12 281 patients with pTBI and 20 338 reference group patients who participated in conscription. A total of 8 507 (66.5%) men in the pTBI group and 14 953 (71.2%) men in the reference group completed military service during the follow-up period. Men in the reference group were more likely to complete military service (OR 1.26, CI 1.18-1.34). A total of 31 (23.3%) men with operatively treated pTBI completed the military service. Men with conservatively treated pTBI had a much higher service rate (OR 7.20, CI 4.73-11.1). In the pTBI group, men (OR 1.26, CI 1.18-1.34) and women (OR 2.05, CI 1.27-3.36) were more likely to interrupt military service than the reference group. The PTBI group scored 0.15 points (CI 0.10-0.20) less than the reference group in cognitive b-test. CONCLUSIONS: PTBI groups had slightly shorter military service periods and higher interruption rate than our reference-group. There were only minor differences between groups in cognitive b-test.

Why all newborn hip screening programs have same results-a mini review.

All newborns are screened for developmental dysplasia of the hip (DDH), but countries have varying screening practices. The aim of this narrative mini review is to discuss the controversies of the screening and why it seems that all screening programs are likely to have same outcome. Different screening strategies are discussed alongside with other factors influencing DDH in this review. Universal ultrasound (US) has been praised as it finds more immature hips than clinical examination, but it has not been proven to reduce the rates of late-detected DDH or surgical management. Universal US screening increases initial treatment rates, while selective US and clinical screening have similar outcomes regarding late detection rates than universal US. This can be explained by the extrinsic factor affecting the development of the hip joint after birth and thus initial screening during the early weeks cannot find these cases.  Conclusion: It seems that DDH screening strategies have strengths and limitations without notable differences in the most severe outcomes (late-detected cases requiring operative treatment). Thus, it is important to acknowledge that the used screening policy is a combination of values and available resources rather than a decision based on clear evidence.

Pediatric traumatic brain injury and early age multiple sclerosis in Finland: A nationwide register-based cohort study.

OBJECTIVE: Examine the link between pediatric traumatic brain injury (pTBI) and early-onset multiple sclerosis in Finland. METHODS: Conducted nationwide register study (1998-2018) with 28,750 pTBI patients (< 18) and 38,399 pediatric references with extremity fractures. Multiple sclerosis diagnoses from Finnish Social Insurance Institution. Employed Kaplan-Meier and multivariable Cox regression for probability assessment, results presented with 95% CI. RESULTS: Of 66 post-traumatic multiple sclerosis cases, 30 (0.10%) had pTBI, and 36 (0.09%) were in the reference group. Cumulative incidence rates (CIR) in the first 10 years were 46.5 per 100,000 (pTBI) and 33.1 per 100,000 (reference). Hazard ratio (HR) for pTBI was 1.10 (95% CI: 0.56-1.48).Stratified by gender, women's CIR was 197.9 per 100,000 (pTBI) and 167.0 per 100,000 (reference) after 15 years. For men, CIR was 44.6 per 100,000 (pTBI) and 34.7 per 100,000 (reference). In the initial 3 years, HR for female pTBI was 1.75 (95% CI: 0.05-6.32), and between years 3 and 20, it was 1.08 (95% CI: 0.51-1.67). For male patients, HR was 1.74 (95% CI: 0.69-4.39). SIGNIFICANCE: We did not find evidence of an association between pTBI and early-onset multiple sclerosis 20 years post-initial trauma.

Open Reduction Internal Fixation vs Primary Arthrodesis for Displaced Lisfranc Injuries: A Multicenter Randomized Controlled Trial.

BACKGROUND: There is no consensus whether the primary surgical method should be open reduction and internal fixation (ORIF) or primary arthrodesis (PA) for Lisfranc injuries. The aim of our randomized controlled trial was to compare ORIF and PA for displaced Lisfranc injuries. METHODS: This study was a national multicenter randomized controlled trial. Altogether 43 displaced Lisfranc injuries were enrolled in this trial. The primary outcome measure was Visual Analogue Scale Foot and Ankle (VAS-FA) at a 24-months follow-up. The secondary outcome measures were VAS-FA pain, function, and other complaints subscales and the American Orthopaedic Foot & Ankle Society (AOFAS) Midfoot Scale. All outcomes were measured at 6, 12, and 24 months. We were unable to reach the planned sample size of 60 patients; thus, the study remains underpowered. RESULTS: The mean VAS-FA Overall score in the ORIF group was 86.5 (95% CI 77.9, 95.1) and 80.1 (95% CI 72.0, 88.1) in the PA group at the 24-month follow-up. We did not find eligible evidence of a difference in VAS-FA Overall scores (mean between-group difference 6.5 [95% CI -5.3, 18.2], Cohen d = 0.100). CONCLUSION: We did not find evidence of a difference in VAS-FA between ORIF and PA in patients with displaced Lisfranc injuries, and thus both are viable options for the initial surgical method. The trial is underpowered; however, the data may be included in a meta-analysis of similarly designed randomized controlled trials.ClinicalTrials.gov identifier: NCT02953067 24 October 2016.

Randomized controlled trials reporting patient-reported outcomes with no significant differences between study groups are potentially susceptible to unjustified conclusions-a systematic review.

OBJECTIVES: Ceiling effect may lead to misleading conclusions when using patient-reported outcome measure (PROM) scores as an outcome. The aim of this study was to investigate the potential source of ceiling effect-related errors in randomized controlled trials (RCTs) reporting no differences in PROM scores between study groups. STUDY DESIGN AND SETTING: A systematic review of RCTs published in the top 10 orthopedic journals according to their impact factors was conducted, focusing on studies that reported no significant differences in outcomes between two study groups. All studies published during 2012-2022 that reported no differences in PROM outcomes and used parametric statistical approach were included. The aim was to investigate the potential source of ceiling effect-related errors-that is, when the ceiling effect suppresses the possible difference between the groups. The proportions of patients exceeding the PROM scales were simulated using the observed dispersion parameters based on the assumed normal distribution, and the differences in the proportions between the study groups were subsequently analyzed. RESULTS: After an initial screening of 2343 studies, 190 studies were included. The central 95% theoretical distribution of the scores exceeded the PROM scales in 140 (74%) of these studies. In 33 (17%) studies, the simulated patient proportions exceeding the scales indicated potential differences between the compared groups. CONCLUSION: It is common to have a mismatch between the chosen PROM instrument and the population being studied increasing the risk of an unjustified "no difference" conclusion due to a ceiling effect. Thus, a considerable ceiling effect should be considered a potential source of error.

Duration of sick leave after operated and non-operated distal radial fracture: a Finnish cohort study of 19,995 patients.

The purpose of this study was to investigate whether operative treatment for distal radial fracture reduces the length of sick leave and the costs of treatment. We identified 19,995 patients from a registry who received a state sick leave allowance between 2010 and 2019 owing to distal radial fractures. We compared these patients to a registry of operations and identified 4346 operated patients. Operated patients had a mean sick leave of 75 days, whereas non-operated patients had a sick leave of 63 days. In the operated group, the cost of sick leave was €7505 (UK£6419; US$8070), which was 34% higher than in the non-operated group. Over the analysed period, the duration of sick leave decreased. Although several studies have shown better early functional outcomes after operation, this does not seem to shorten sick leave.Level of evidence: III.

Association between pediatric traumatic brain injury and epilepsy at later ages in Finland: A nationwide register-based cohort study.

OBJECTIVE: This study was undertaken to examine how pediatric traumatic brain injury (pTBI) correlates with incidence of epilepsy at later ages in Finland. METHODS: This nationwide retrospective register-based cohort study extended from 1998 to 2018. The study group consisted of 71 969 pediatric (<18 years old) patients hospitalized with TBI and a control group consisting of 64 856 pediatric patients with distal extremity fracture. Epilepsy diagnoses were gathered from the Finnish Social Insurance Institution. Kaplan-Meier and multivariable Cox regression models were conducted to analyze the probability of epilepsy with 95% confidence intervals (CIs). RESULTS: Cumulative incidence rates (CIRs) for the first 2 years were .5% in the pTBI group and .1% in the control group. The corresponding rates after 15 years of follow-up were 1.5% in the pTBI group and .7% in the control group. Due to proportional hazard violations, the study population was split to the first 2 years and in subgroup analysis 4 years. During the first 2 years of surveillance, the hazard ratio (HR) for the pTBI group was 4.38 (95% CI = 3.39-5.66). However, between years 2 and 20, the HR for the pTBI group was 2.02 (95% CI = 1.71-2.38). A total of 337 patients (.47%) underwent neurosurgery, and 36 (10.7%) patients subsequently developed epilepsy. The CIR for the first year after TBI was 4.5% (95% CI = 2.3-6.7) in operatively managed patients and .3% (95% CI = .3-.4) in nonoperatively managed patients. Corresponding figures after 15 years were 12.0% (95% CI = 8.2-15.8) and 1.5% (95% CI = 1.4-1.6). During the first 4 years of surveillance, the HR for the operative pTBI group was 14.37 (95% CI = 9.29-20.80) and 3.67 (95% CI = 1.63-8.22) between years 4 and 20. SIGNIFICANCE: pTBI exposes patients to a higher risk for posttraumatic epilepsy for many years after initial trauma. Children who undergo operative management for TBI have a high risk for epilepsy, and this risk was highest during the first 4 years after injury.
