Roughly two-thirds of ankle fractures are unimalleolar injuries, the Weber B-type fibula fracture being by far the most common type. Depending on the trauma and the accompanying soft-tissue injury, these fractures are either stable or unstable. Current clinical practice guidelines recommend surgical treatment for unstable Weber B-type fibula fractures. An ongoing randomized, parallel group, non-inferiority trial comparing surgery and non-operative treatment for unstable Weber B-type ankle fractures with allocation ratio 1:1. The rationale for non-inferiority design is as follows: By being able to prove non-inferiority of non-operative treatment, we would be able to avoid complications related to surgery. However, the primary concern related to non-operative treatment is increased risks of ankle mortise incongruency, leading to secondary surgery, early post-traumatic osteoarthritis and poor function. After providing informed consent, 126 patients aged 16 years or older with an unimalleolar Weber B-type unstable fibula fracture were randomly assigned to surgery (open reduction and internal fixation) or non-operative treatment (6-week cast immobilization). We have completed the patient enrolment and are currently in the final stages of the 2-year follow-up. The primary, non-inferiority outcome is the Olerud-Molander Ankle Score (OMAS) at 2 years (primary time point). The predefined non-inferiority margin is set at 8 OMAS points. Secondary outcomes include the Foot and Ankle Score, a 100 mm Visual Analogue Scale for function and pain, the RAND-36-Item Health Survey for health-related quality-of-life, the range-of-motion of the injured ankle, malunion (ankle joint incongruity) and fracture union. Treatment-related complications and harms; symptomatic non-unions, loss of congruity of the ankle joint, reoperations and wound infections will also be recorded. We hypothesize that non-operative treatment yields non-inferior functional outcome to surgery, the current s

Introduction: Chronic subdural haematomas (CSDHs) are one of the most common neurosurgical conditions. The goal of surgery is to alleviate symptoms and minimise the risk of symptomatic recurrences. In the past, reoperation rates as high as 20%–30% were described for CSDH recurrences. However, following the introduction of subdural drainage, reoperation rates dropped to approximately 10%. The standard surgical technique includes burr-hole craniostomy, followed by intraoperative irrigation and placement of subdural drainage. Yet, the role of intraoperative irrigation has not been established. If there is no difference in recurrence rates between intraoperative irrigation and no irrigation, CSDH surgery could be carried out faster and more safely by omitting the step of irrigation. The aim of this multicentre randomised controlled trial is to study whether no intraoperative irrigation and subdural drainage results in non-inferior outcome compared with intraoperative irrigation and subdural drainage following burr-hole craniostomy of CSDH. Methods and analysis: This is a prospective, randomised, controlled, parallel group, non-inferiority multicentre trial comparing single burr-hole evacuation of CSDH with intraoperative irrigation and evacuation of CSDH without irrigation. In both groups, a passive subdural drain is used for 48 hours as a standard of treatment. The primary outcome is symptomatic CSDH recurrence requiring reoperation within 6 months. The predefined non-inferiority margin for the primary outcome is 7.5%. To achieve a 2.5% level of significance and 80% power, we will randomise 270 patients per group. Secondary outcomes include modified Rankin Scale, rate of mortality, duration of operation, length of hospital stay, adverse events and change in volume of CSDH. Ethics and dissemination: The study was approved by the institutional review board of the Helsinki and Uusimaa Hospital District (HUS/3035/2019 §238) and duly registered at ClinicalTrials.go

Background: The relevance of health-related behaviors to exclusion from the labor market in early adulthood remains poorly studied in relation to the magnitude of the problem. We explored whether adolescents’ accumulated unhealthy behaviors and psychosocial problems are associated with later labor market exclusion, and whether multisite musculoskeletal pain (MMSP) impacts these relations. Methods: We gathered questionnaire data on unhealthy behaviors and psychosocial problems and MMSP among adolescents aged 15 to 16 belonging to the Northern Finland Birth Cohort 1986. The findings were combined with registry data on unemployment, employment and permanent work disability during a five-year follow-up between the ages of 25 and 29 (n = 6692). In the statistical modeling we used education, family leave and socioeconomic status of childhood family as potential confounders, as well as latent class and logistic regression analyses. Results: The Externalizing behavior cluster associated with over one year of unemployment (RR 1.64, CI 1.25–2.14) and permanent work disability (OR 2.49, CI 1.07–5.78) in the follow-up among the men. The Sedentary cluster also associated with over one year (RR 1.41, CI 1.13–1.75) and under one year of unemployment (RR 1.25, CI 1.02–1.52) and no employment days (RR 1.93, CI 1.26–2.95) among the men. Obese male participants were at risk of over one year of unemployment (RR 1.50, CI 1.08–2.09) and no employment days (RR 1.93, CI 1.07–3.50). Among the women, the Multiple risk behavior cluster related significantly to over one year of unemployment (RR 1.77, CI 1.37–2.28). MMSP had no influence on the associations. Conclusions: Unhealthy behavior patterns and psychosocial problems in adolescence have long-term consequences for exclusion from the labor market in early adulthood, especially among men. Simultaneously supporting psychological well-being and healthy behaviors in adolescence may reduce labor market inclusion difficulties in the ear

Unhealthy behaviours and psychosocial problems often coincide during adolescence. Previous literature has connected these factors separately to musculoskeletal (MS) pains and difficulties in labour market inclusion. However, little is known about the influence of co-occurring health-related behaviour patterns on MS pains and labour market exclusion. This Northern Finland Birth Cohort 1986 study evaluated the co-occurrence of unhealthy behaviours and psychosocial problems among 15–16-year-old adolescents, and estimated the determinant value of co-occurring health-related behaviours in explaining low back pain (LBP) and recurrent multisite musculoskeletal pain (MMSP) between the ages 15 and 19. It also determined exclusion from the labour market during a five-year follow-up period between the ages of 25 and 29, and studied the stability of the unhealthy behaviours between the ages of 15 and 19 and the possible influence of MMSP on the relationships between co-occurring health-related patterns and difficulties in labour market inclusion. Information on health-related behaviours and MS pains were gathered via two questionnaires. The labour market data, including data on unemployment, employment and permanent work disability, were based on national registers. Latent class analysis (LCA) was utilized to study the accumulation of the health-related behaviours. Psychosocial problems and unhealthy behaviours divided adolescents into four subgroups (clusters), in which unhealthy behaviours persisted between the ages of 15 and 19. Belonging to the Psychosocial cluster, in which the prevalence of smoking and physical activity were at a moderate/high level, was associated with LBP and recurrent MMSP among both genders, whereas belonging to the Psychosocial cluster and having several unhealthy behaviours (=Multiple risk behaviours cluster) was associated with LBP and recurrent MMSP among women. Belonging to the Obese cluster was also associated with LBP among women, wher, Tiivistelmä Nuorten epäedulliset elintavat ja psykososiaaliset ongelmat liittyvät usein toisiinsa. Aiemmat tutkimukset ovat yhdistäneet nämä tekijät nuoruuden ja varhaisaikuisuuden tuki- ja liikuntaelinkipuihin sekä työelämään kiinnittymisen vaikeuksiin, mutta niiden yhteisvaikutus tunnetaan puutteellisesti. Tässä Pohjois-Suomen syntymäkohortti 1986:een pohjautuvassa tutkimuksessa selvitettiin 15–16-vuotiaiden nuorten psykososiaalisten ongelmien ja epäedullisten elintapojen yhteisesiintyvyyttä ja arvioitiin niiden yhteyttä alaselkäkipuun ja toistuvaan monipaikkaiseen kipuun kahden vuoden seurannassa sekä yhteyttä työelämään kiinnittymättömyyteen viiden vuoden seurantajaksolla 25–29 vuoden iässä. Lisäksi analysoitiin epäedullisten elintapojen pysyvyyttä 15–19 vuoden iässä sekä monipaikkaisen kivun mahdollista vaikutusta havaittuihin yhteyksiin kasautuneiden psykososiaalisten ongelmien ja epäedullisten elintapojen ja työelämään kiinnittymättömyyden välillä. Tiedot terveyteen liittyvistä tekijöistä ja tuki- ja liikuntaelinkivuista kerättiin kahden kyselyn avulla. Työelämäaineisto perustui kansallisiin rekistereihin. Latent Class Analysis-menetelmällä selvitettiin psykososiaalisten ongelmien ja epäedullisten elintapojen kasautumista. Psykososiaalisten ongelmien ja epäedullisten elintapojen perusteella nuoret muodostivat neljä ryhmää, joissa epäedulliset elintavat säilyivät 15–19 vuoden iässä. Kuuluminen ryhmään, jossa korostui psykososiaalisten ongelmien lisäksi tupakointi ja fyysinen aktiivisuus sekä miehillä että naisilla, tai useat haitalliset tekijät naisilla, oli yhteydessä alaselkäkipuun ja toistuvaan monipaikkaiseen tuki- ja liikuntaelinkipuun. Lihavien naisten ryhmä yhdistyi alaselkäkipuun, kun taas ryhmä, jota kuvasi runsas istuminen ja fyysinen inaktiivisuus, yhdistyi toistuvaan monipaikkaiseen tuki- ja liikuntaelinkipuun miehillä. Kuuluminen mihin tahansa epäedulliseen ryhmään ennusti miehillä työelämän ulkopuolelle jäämistä. Naisilla samanlainen yhteys löyde

Background: Musculoskeletal (MS) pain is common. It often exists in several sites and is recurrent. Psychosocial difficulties and unhealthy behaviours have been related to multisite MS pain, but no literature has assessed the impact of accumulated psychosocial and lifestyle factors on recurrent multiple MS pain. Methods: Our data were gathered from two questionnaires of the well‐known Northern Finland Birth Cohort 1986 (NFBC1986), sent to members when they were aged 16 and 18. A total of 1,625 adolescents (712 boys and 913 girls) answered questions on smoking, physical activity, sedentary behaviour, sleeping and emotional and behavioural problems at 16 years and on musculoskeletal pain at 16 and 18 years. Weight and height measurements were taken at a health examination at baseline. A latent class analysis and multinomial regression analysis were conducted. Results: We identified four clusters among both sexes. “Externalizing behavior” among both genders (OR 2.98, CI 1.73–5.13 among boys; OR 2.38, CI 1.38–4.11 among girls), “Multiple risk behaviors” among girls (OR 2.73, CI 1.30–5.71) and a “Sedentary” cluster among boys (OR 1.85, CI 1.21–2.82) were associated to recurrent multisite MS pain. “Obese” clusters had no significant associations with recurrent multiple MS pain. Conclusions: Adolescents with psychosocial difficulties and/or several adverse health behaviours were at an increased risk of recurrent multisite MS pain, which emphasizes the importance of simultaneously studying multiple rather than single factors. The identification of risk groups may help more accurately target preventive interventions. Significance:/ This study found subgroups of adolescents at risk of recurrent multisite musculoskeletal pain during late adolescence. The accumulation of multiple adverse behaviours is likely to provide new perspectives for understanding the multidimensional nature of multiple MS pains.

Background: We assessed the effectiveness of three interventions that were aimed to reduce non-acute low back pain (LBP) related symptoms in the occupational health setting. Methods: Based on a survey (n = 2480; response rate 71%) on LBP, we selected a cohort of 193 employees who reported moderate LBP (Visual Analogue Scale VAS > 34 mm) and fulfilled at least one of the following criteria during the past 12 months: sciatica, recurrence of LBP ≥ 2 times, LBP ≥ 2 weeks, or previous sickness absence. A random sample was extracted from the cohort as a control group (Control, n = 50), representing the natural course of LBP. The remaining 143 employees were invited to participate in a randomised controlled trial (RCT) of three 1:1:1 allocated parallel intervention arms: multidisciplinary rehabilitation (Rehab, n = 43); progressive exercises (Physio, n = 43) and self-care advice (Advice, n = 40). Seventeen employees declined participation in the intervention. The primary outcome measures were physical impairment (PHI), LBP intensity (Visual Analogue Scale), health related quality of life (QoL), and accumulated sickness absence days. We imputed missing values with multiple imputation procedure. We assessed all comparisons between the intervention groups and the Control group by analysing questionnaire outcomes at 2 years with ANOVA and sickness absence at 4 years by using negative binomial model with a logarithmic link function. Results: Mean differences between the Rehab and Control groups were − 3 [95% CI -5 to − 1] for PHI, − 13 [− 24 to − 1] for pain intensity, and 0.06 [0.00 to 0.12] for QoL. Mean differences between the Physio and Control groups were − 3 [95% CI -5 to − 1] for PHI, − 13 [− 29 to 2] for pain intensity, and 0.07 [0.01 to 0.13] for QoL. The main effects sizes were from 0.4 to 0.6. The interventions were not effective in reducing sickness absence. Conclusions: Rehab and Physio interventions improved health related quality of life, decreased low b

Objectives. To examine the relative efficacy of three active therapies for patients with chronic low back pain. Methods. One hundred and forty‐eight subjects with chronic low back pain were randomized to receive, twice weekly for 3 months, (i) active physi otherapy, (ii) muscle reconditioning on training devices, or (ii) low‐impact aerobics. Questionnaires were administered to assess pain intensity, pain frequency and disability before and after therapy and at 6 and 12 months of follow‐up. Results. One hundred and thirty‐two of the 148 patients (89%) completed the therapy programmes and 127 of the 148 (86%) returned a questionnaire at all four time‐points. The three treatments were equally efficacious in significantly reducing pain intensity and frequency for up to 1 yr after therapy. However, the groups differed with respect to the temporal changes in self‐rated disability over the study period (P=0.03): all groups showed a similar reduction after therapy, but for the physiotherapy group disability increased again during the first 6 months of follow‐up whilst the other two groups showed a further decline. In all groups the values then remained stable up to the 12‐month follow‐up. The larger group size and minimal infrastructure required for low‐impact aerobics rendered it considerably less expensive to administer than the other two programmes. Conclusions. The introduction of low‐impact aerobic exercise programmes for patients with chronic low back pain may reduce the enormous costs associated with its treatment

Background: Evidence shows that low back specific patient information is effective in sub-acute low back pain (LBP), but effectiveness and cost-effectiveness (CE) of information in early phase symptoms is not clear. We assessed effectiveness and CE of patient information in mild LBP in the occupational health (OH) setting in a quasi-experimental study. Methods: A cohort of employees (N = 312, aged Results: Compared to NC, the Booklet reduced HC costs by 196(sic) and SA by 3.5 days per year. In 81 % of the bootstrapped cases the Booklet was both cost saving and effective on SA. Compared to NC, in the Combined arm, the figures were 107(sic), 0.4 days, and 54 %, respectively. PHI decreased in both interventions. Conclusions: Booklet information alone was cost-effective in comparison to natural course of mild LBP. Combined information reduced HC costs. Both interventions reduced physical impairment. Mere booklet information is beneficial for employees who report mild LBP in the OH setting, and is also cost saving for the health care system.

Earlier studies on lumbar degenerative imaging findings in magnetic resonance imaging (MRI) have been done mainly in adult populations and the associations of degenerative findings with low back pain (LBP) are controversial. Only a few studies have involved adolescents and young adults. Heritability has been acknowledged as the only explicit risk factor of disc degeneration (DD). This study investigated the prevalence and environmental determinant of lumbar degenerative findings in MRI and their association with low back symptoms among young adults. The data were based on two physical assessments, three questionnaires and one lumbar MRI that were executed on members of the Oulu Back Study (n=558), a subsample of Northern Finland Birth Cohort 1986, between 16 and 21 years of age. Prevalences of lumbar DD (54%), bulging (25%), protrusion (18%) and Schmorl’s node (17%) were high, whereas other degenerative findings were rare among young adults. Males had higher prevalence of DD and Schmorl’s nodes than females. DD and herniations were associated with low back symptoms. On the other hand, symptoms were present among subjects without DD or other abnormal findings on MRI. Of the environmental determinants, high body mass index and MRI-based obesity measurements of visceral adiposity were associated with lumbar DD among males. Waist circumference and smoking showed a comparable association with DD among males, but the level of physical activity was not associated with DD in either gender. Low back symptoms are more common among young adults with a higher degree of DD or presence of disc herniation. Smoking and overweight are associated with lumbar DD among young male adults., Tiivistelmä Aikaisempia tutkimuksia magneettikuvantamisella (MK) todetuista lannerangan rappeumamuutoksista ja niiden yhteyksistä alaselkäkipuun on tehty lähinnä aikuisväestöllä ja tulokset ovat ristiriitaisia. Vain muutamia tutkimuksia on tehty alle 25-vuotiailla. Välilevyrappeuman mahdollisista riskitekijöistä vain perimästä on vahvaa näyttöä. Tässä tutkimuksessa tarkasteltiin MK:lla todettujen lannerangan rappeumamuutosten esiintyvyyttä, niihin vaikuttavia ympäristötekijöitä ja yhteyttä alaselkäoireisiin nuorilla aikuisilla. Tutkimuksen aineisto perustui kahteen kliiniseen tutkimukseen, kolmeen kyselyyn ja yhteen MK:een, jotka toteutettiin Pohjois-Suomen syntymäkohortti 1986:een kuuluville Oulun selkätutkimuksen koehenkilöille (n=558) 16–21 vuoden iässä. Lannerangan välilevyrappeumalla (54 %), välilevyn pullotuksilla (bulge; 25 %), sellaisilla välilevyn pullistumilla jotka eivät läpäisseet selkärangan takimmaista pitkittäissidettä (protruusio; 18 %) sekä päätelevyn läpi suuntautuvilla välilevyn pullistumilla (Schmorlin keräset; 17 %) oli korkea esiintyvyys nuorilla aikuisilla, kun taas muut kuvantamislöydökset olivat harvinaisia. Välilevyrappeuma ja Schmorlin keräset olivat yleisempiä miehillä. Sekä välilevyrappeuma että pullistumat olivat yhteydessä alaselkäoireisiin molemmilla sukupuolilla, mutta kaikilla oireisilla ei todettu poikkeavia löydöksiä MK:ssa. Ympäristötekijöistä korkea kehon painoindeksi ja MK:sta mitatut rasvan määrää mittaavat muuttujat olivat miehillä yhteydessä välilevyrappeumaan. Miehillä vyötärönympärys ja tupakointi olivat heikommin yhteydessä välilevyrappeumaan, kun taas liikunta-aktiivisuus ei ollut kummallakaan sukupuolella yhteydessä rappeumaan. Alaselkäoireet ovat yleisempiä nuorilla aikuisilla, joilla on vaikea-asteisempi välilevyrappeuma tai välilevyn pullistuma. Tupakointi ja ylipaino ovat yhteydessä lannerangan välilevyrappeumaan nuorilla aikuisilla miehillä.

Background: Adolescents’ psychosocial problems associate with unhealthy behaviors, but data on co-occurring patterns is sparse. We investigated 1) whether adolescents could be categorized into meaningful subgroups with respect to psychosocial and lifestyle factors, 2) whether the prevalence of physical inactivity, overweight and smoking vary within the subgroups and 3) whether these unhealthy behaviors persist in a two-year follow-up. Methods: The study was based on a subgroup of the 1986 Northern Finland Birth Cohort, which consisted of adolescents who replied to a postal questionnaire at 16 years (n = 6792) and a subgroup of this sample at 18 years (n = 1552). Latent class analysis (LCA) was performed to establish clusters at 16 years. Results: Smoking co-existed with emotional and behavioral problems in both genders. Boys with the most inactive lifestyle slept poorly, whereas multiple problems co-occurred among girls. Those with a high body mass index (BMI) separated as groups of their own. Different combinations of adverse lifestyle and emotional and behavioral problems were relatively common in both sexes as only 51% of boys and 67% of girls belonged to the reference cluster with low probability for these findings. Physical inactivity, high BMI and smoking tended to persist over the two-year follow-up. Conclusions: It seems that lifestyle and psychosocial factors divide adolescents into distinct subgroups in which unhealthy lifestyle patterns remain between the ages of 16 and 18. This may indicate problems in other life areas and expose them to an increased risk of future health problems.

Recent studies in adults have shown that musculoskeletal (MS) pains are often experienced at several body sites. The number of pain sites has been shown to be proportional to poor health outcomes, such as functional ability and health-related quality of life (HRQoL). This study investigated the occurrence and persistence of MS pain in multiple locations, determinants of multiple-site pain, and the impact of multiple-site pain on HRQoL and health care use among adolescents aged 16 to 19. The data were based on three inquiries that were administered to the adolescents of the Northern Finland Birth Cohort 1986. MS pain was common and often occurred at multiple sites. Moreover, the majority of adolescents with multiple-site pain at 16 reported multiple-site pain also at 18. Multiple-site MS pains were strongly associated with psychosocial complaints, but also with high physical activity level, long sitting time, short sleeping time, smoking, and overweight. Emotional problems, behavioral problems, and high sitting time among males, and emotional problems, high physical activity level, short sleeping time, and smoking among females were predictive factors for the persistence of multiple-site pain. The likelihood of reduced HRQoL increased according to the number of MS pain sites. A trend toward an increase in health care use with the number of pain sites was also observed. Reporting pain in multiple sites in adolescence may have both peripheral (tissue origin) and central (pain experience) causes. As multiple-site pain in adolescence may predict subsequent MS morbidity, the adolescents who are at highest risk and also at the highest need of health promotion should be identified in further studies., Tiivistelmä Aikuisväestössä tehtyjen tutkimusten perusteella tuki- ja liikuntaelimistön kivut esiintyvät tavallisesti usealla kehon alueella samanaikaisesti. Monikipuisuudella näyttää olevan epäedullisia vaikutuksia useisiin terveyteen liittyviin ilmiöihin kuten toiminta- ja työkykyyn sekä elämänlaatuun. Tässä tutkimuksessa tarkasteltiin monipaikkaisen tuki- ja liikuntaelinkivun esiintyvyyttä, pysyvyyttä ja riskitekijöitä sekä sen vaikutusta terveyteen liittyvään elämänlaatuun ja terveyspalvelujen käyttöön 16–19 -vuotiailla nuorilla. Tutkimuksen aineisto perustui kolmeen kyselyyn, jotka lähetettiin Pohjois-Suomen syntymäkohortti 1986:n nuorille. Tuki- ja liikuntaelinkipu oli yleistä ja esiintyi tavallisimmin usealla kehon alueella. Suurin osa nuorista, jotka raportoivat monen paikan kipua 16-vuotiaana, raportoivat sitä myös 18-vuotiaana. Monen kehon alueen tuki- ja liikuntaelinkipu yhdistyi voimakkaasti psykososiaalisiin tekijöihin, mutta myös korkeaan liikunta-aktiivisuuteen, runsaaseen istumiseen, vähäiseen uneen, tupakointiin ja ylipainoon. Käyttäytymisen- ja tunne-elämän häiriöt sekä runsas istuminen pojilla, ja tunne-elämän häiriöt, korkea liikunnallinen aktiivisuus, vähäinen uni sekä tupakointi tytöillä ennustivat monen kehon alueen kivun pysyvyyttä. Todennäköisyys heikentyneeseen terveyteen liittyvään elämänlaatuun lisääntyi suhteessa kipualueiden määrään. Myös terveyspalvelujen käytön ja kipualueiden lukumäärän välillä havaittiin yhteys. Monen paikan tuki- ja liikuntaelinkipua selittänevät sekä kudostasoiset että keskushermostolliset syyt. Koska laaja-alainen kipuoireilu nuoruudessa voi ennustaa myöhempiä tuki- ja liikuntaelinongelmia, riskiryhmiä ja samalla eniten terveyden edistämistä tarvitsevia nuoria tulisi pyrkiä jatkossa tarkemmin tunnistamaan.
