BACKGROUND. The kynurenine pathway (KP) has been identified as a potential mediator linking acute illness to cognitive dysfunction by generating neuroactive metabolites in response to inflammation. Delirium (acute confusion) is a common complication of acute illness and is associated with increased risk of dementia and mortality. However, the molecular mechanisms underlying delirium, particularly in relation to the KP, remain elusive. METHODS. We undertook a multicenter observational study with 586 hospitalized patients (248 with delirium) and investigated associations between delirium and KP metabolites measured in cerebrospinal fluid (CSF) and serum by targeted metabolomics. We also explored associations between KP metabolites and markers of neuronal damage and 1-year mortality. RESULTS. In delirium, we found concentrations of the neurotoxic metabolite quinolinic acid in CSF (CSF-QA) (OR 2.26 [1.78, 2.87], P < 0.001) to be increased and also found increases in several other KP metabolites in serum and CSF. In addition, CSF-QA was associated with the neuronal damage marker neurofilament light chain (NfL) (p 0.43, P < 0.001) and was a strong predictor of 1-year mortality (HR 4.35 [2.93, 6.45] for CSF-QA > 100 nmol/L, P < 0.001). The associations between CSF-QA and delirium, neuronal damage, and mortality remained highly significant following adjustment for confounders and multiple comparisons. CONCLUSION. Our data identified how systemic inflammation, neurotoxicity, and delirium are strongly linked via the KP and should inform future delirium prevention and treatment clinical trials that target enzymes of the KP. FUNDING. Norwegian Health Association and South-Eastern Norway Regional Health Authorities., Introduction The kynurenine pathway (KP) has been identified as a potential mediator linking acute illness to cognitive dysfunction by generating neuroactive metabolites in response to inflammation (1, 2).

Alterations in brain energy metabolism have long been proposed as one of several neurobiological processes contributing to delirium. This is supported by previous findings of altered CSF lactate and neuron-specific enolase concentrations and decreased glucose uptake on brain-PET in patients with delirium. Despite this, there are limited data on metabolic alterations found in CSF samples, and targeted metabolic profiling of CSF metabolites involved in energy metabolism has not been performed. The aim of the study was to investigate whether metabolites related to energy metabolism in the serum and CSF of patients with hip fracture are associated with delirium. The study cohort included 406 patients with a mean age of 81 years (standard deviation 10 years), acutely admitted to hospital for surgical repair of a hip fracture. Delirium was assessed daily until the fifth postoperative day. CSF was collected from all 406 participants at the onset of spinal anaesthesia, and serum samples were drawn concurrently from 213 participants. Glucose and lactate in CSF were measured using amperometry, whereas plasma glucose was measured in the clinical laboratory using enzymatic photometry. Serum and CSF concentrations of the branched-chain amino acids, 3-hydroxyisobutyric acid, acetoacetate and β-hydroxybutyrate were measured using gas chromatography-tandem mass spectrometry (GC-MS/MS). In total, 224 (55%) patients developed delirium pre- or postoperatively. Ketone body concentrations (acetoacetate, β-hydroxybutyrate) and branched-chain amino acids were significantly elevated in the CSF but not in serum among patients with delirium, despite no group differences in glucose concentrations. The level of 3-hydroxyisobutyric acid was significantly elevated in both CSF and serum. An elevation of CSF lactate during delirium was explained by age and comorbidity. Our data suggest that altered glucose utilization and a shift to ketone body metabolism occurs in the brain during delirium. [ABSTRACT FROM AUTHOR]

Background and purpose — Better outcomes are reported for suture button (SB) compared with syndesmotic screws (SS) in patients treated for an acute ankle syndesmotic injury. One reason could be that screws are more rigid than an SB. A single tricortical 3.5 mm syndesmotic screw (TS) is the most dynamic screw option. Our hypothesis is that 1 SB and 1 TS provide similar results. Therefore, in randomized controlled trial, we compared the results between SB and TS for syndesmotic stabilization in patients with acute syndesmosis injury. Patients and methods — 113 patients with acute syndesmotic injury were randomized to SB (n = 55) or TS (n = 58). The American Orthopedic Foot & Ankle Society (AOFAS) Ankle–Hindfoot Score was the primary outcome measure. Secondary outcome measures included Manchester Oxford Foot Questionnaire (MOXFQ), Olerud–Molander Ankle score (OMA), visual analogue scale (VAS), EuroQol- 5D (EQ-5D), radiologic results, range of motion, complications, and reoperations (no implants were routinely removed). CT scans of both ankles were obtained after surgery, and after 1 and 2 years. Results — The 2-year follow-up rate was 84%. At 2 years, median AOFAS score was 97 in both groups (IQR SB 87–100, IQR TS 90–100, p = 0.7), median MOXFQ index was 5 in the SB group and 3 in the TS group (IQR 0–18 vs. 0–8, p = 0.2), and median OMA score was 90 in the SB group and 100 in the TS group (IQR 75–100 vs. 83–100, p = 0.2). The syndesmotic reduction was similar 2 years after surgery; 19/55 patients in the SB group and 13/58 in the TS group had a difference in anterior syndesmotic width ≥ 2 mm (p = 0.3). 0 patients in the SB group and 5 patients in the TS group had complete tibiofibular synostosis (p = 0.03). At 2 years, 10 TS were broken. Complications and reoperations were similar between the groups. Interpretation — We found no clinically relevant differences regarding outcome scores between the groups. TS is an inexpensive alternative to SB. [ABSTRACT FROM AUTHOR]

- Abstract
Objective We assessed compliance with new guidelines for prophylactic antibiotics in hip fracture surgery in Norway introduced in 2013. Design The data from the Norwegian Hip Fracture Register was used to assess the proportion of antibiotics given according to the national guidelines. Setting All hospitals in Norway performing hip fracture surgery in the period from 2011 to 2016. Participants We studied 13 329 hemiarthroplasties (HAs) for acute hip fracture. Main outcome measure Type and timing between first and last dose of prophylactic antibiotics compared with the national guidelines. Results Before the guidelines were introduced, the recommended drugs cephalotin or clindamycin was used in only 86.2% of all HAs. In 2016, one of the two recommended drugs was administered in 99.2% of HAs. However, hospitals’ adaption of the recommended administration of the two drugs improved slowly, and by the end of the study period, only three out of five HAs were performed with the correct drug administered in the correct manner. We found major differences in compliance between hospitals. Conclusions The change towards correct administration of antibiotic prophylaxis was varied both when investigating university and non-university hospitals. We suggest that both hospital leaders and the national Directorate of Health need to investigate routines for better dissemination of information and education to involved parties. Strong leadership concerning evidence based guidelines on antibiotic prophylaxis in surgery may take away some autonomy from executing healthcare professionals, but will result in better patient care and antibiotic stewardship [ABSTRACT FROM AUTHOR]

- Abstract
The location of osteoporotic fragility fractures adds crucial information to post‐fracture risk estimation. Triaging patients according to fracture site for secondary fracture prevention can therefore be of interest to prioritize patients considering the high imminent fracture risk. The objectives of this cross‐sectional study were therefore to explore potential differences between central (vertebral, hip, proximal humerus, pelvis) and peripheral (forearm, ankle, other) fractures. This substudy of the Norwegian Capture the Fracture Initiative (NoFRACT) included 495 women and 119 men ≥50 years with fragility fractures. They had bone mineral density (BMD) of the femoral neck, total hip, and lumbar spine assessed using dual‐energy X‐ray absorptiometry (DXA), trabecular bone score (TBS) calculated, concomitantly vertebral fracture assessment (VFA) with semiquantitative grading of vertebral fractures (SQ1–SQ3), and a questionnaire concerning risk factors for fractures was answered. Patients with central fractures exhibited lower BMD of the femoral neck (765 versus 827 mg/cm2), total hip (800 versus 876 mg/cm2), and lumbar spine (1024 versus 1062 mg/cm2); lower mean TBS (1.24 versus 1.28); and a higher proportion of SQ1‐SQ3 fractures (52.0% versus 27.7%), SQ2–SQ3 fractures (36.8% versus 13.4%), and SQ3 fractures (21.5% versus 2.2%) than patients with peripheral fractures (all p < 0.05). All analyses were adjusted for sex, age, and body mass index (BMI); and the analyses of TBS and SQ1–SQ3 fracture prevalence was additionally adjusted for BMD). In conclusion, patients with central fragility fractures revealed lower femoral neck BMD, lower TBS, and higher prevalence of vertebral fractures on VFA than the patients with peripheral fractures. This suggests that patients with central fragility fractures exhibit more severe deterioration of bone structure, translating into a higher risk of subsequent fragility fractures and therefore they should get the highest priority in secondary fracture prevention, although attention to peripheral fractures should still not be diminished. © 2019 American Society for Bone and Mineral Research. © 2019 The Authors.

- Abstract
A long track speed skater sustained a deep horizontal cut to the right knee just distally to the patella, after he got hit by the skate blade of the pair mate. The injury included a complete patellar tendon rupture from the apex of the patella, a 1 mm deep transverse cut in the femoral condyle and a partial rupture of the anterior cruciate ligament. The tendon rupture was repaired with transosseous suture repair without augmentation. A knee brace was used for 8 weeks, with a gradual decrease in flexion restraints. A rehabilitation programme was overseen by a dedicated physiotherapist. At 6 months, he started a gradual return to skating sessions. After 1 year, he had symmetrical single-legged hop performance, but quadriceps weakness due to pain. The patient returned to competition speed skating at national levels after 11 months, and within the first postoperative year, he was breaking new personal records on the ice. [ABSTRACT FROM AUTHOR]

Background and purpose — The use of unipolar hemiarthroplasties for femoral neck fractures is increasing in some countries due to reports of higher reoperation rates in bipolar prostheses. On the other hand, it has been proposed that bipolar hemiarthroplasties have clinical advantages and less cartilage wear than unipolar hemiarthroplasties. We compared cartilage wear between bipolar and unipolar hemiarthroplasties using radiostereometric analyses (RSA), in patients aged 70 years or older. Patients and methods — 28 ambulatory, lucid patients were randomized to treatment with a unipolar or a bipolar hemiarthroplasty for an acute femoral neck fracture. Migration of the prosthetic head into the acetabulum was measured using RSA. Secondary outcomes were Harris Hip Score (HHS), and EQ-5D scores. Patients were assessed at 3, 12. and 24 months. Results — 19 patients were available for follow-up at 2 years: mean proximal penetration was 0.83 mm in the unipolar group and 0.24 mm in the bipolar group (p = 0.01). Mean total point movement was 1.3 mm in the unipolar group and 0.95 mm in the bipolar group (p = 0.3). Median HHS was 78 (62-96) in the unipolar group and 100 (70-100) in the bipolar group (p = 0.004). Median EQ-5D Index Score was 0.73 (0.52-1.00) in the unipolar group and 1.00 (0.74-1.00) in the bipolar group (p = 0.01). Median EQ-5D VAS was 70 (50-90) in the unipolar group and 89 (70-95) in the bipolar group (p = 0.03) Interpretation — Patients with unipolar hemiarthroplasties had higher proximal cartilage wear and lower functional outcomes. Unipolar hemiarthroplasties should be used with caution in ambulatory, lucid patients. [ABSTRACT FROM AUTHOR]

Introduction Cartilage wear is a concern after hemiarthroplasty. The precise pattern of the progression of wear has not been evaluated. We previously reported the application of radiostereonetric analysis (RSA) for the measurement of cartilage wear in patients. The purpose of this study was to report the amount and the orientation of the steady state wear of cartilage between 1 and 3 years after bipolar hemiarthroplasty. Methods 22 patients with a bipolar hemiarthroplasty for displaced femoral neck fracture were included. 10 patients completed the mean follow up of 37 months. The cartilage wear was evaluated by calculating the migration of the bipolar head in reference to the markers in the acetabulum using RSA. Results The mean age of the patients at the final follow-up was 80 (range 67-91) years. The 3-D migration was -0.02 mm (SD 0.30) between 1 and 3 years. The migration in each direction was 0.03 mm (SD 0.49) in medial, 0.03 mm (SD 0.14) in proximal and 0.11 mm (SD 0.29) in posterior directions. 2 patients showed migration of more than 0.2 mm. The large initial migration seen in some patients up to 1 year did not progress further. Total wear after 37 months was 0.43 mm (SD 0.17). Conclusions Cartilage wear progressed slowly in 2 of 10 patients from 1 to 3 years. No pelvic penetration was seen. We believe that RSA will give a basic knowledge about the development and the progression of cartilage wear after hemiarthroplasty. [ABSTRACT FROM AUTHOR]

Background and purpose - Registry-based studies have reported an increased risk of aseptic tibial loosening for the cemented Low Contact Stress (LCS) total knee replacement compared with other cemented designs; however, the reasons for this have not been established. We made a retrieval analysis with the aim of identifying the failure mechanism. Patients and methods - We collected implants, cement, tissue, blood, and radiographs from 32 failed LCS Complete cases. Damage to the tibial baseplate and insert was assessed. Exposure to wear products was quantified in 11 cases through analysis of periprosthetic tissue and blood. Implant alignment and bone cement thickness was compared with a control group of 43 nonrevised cases. Results - Loosening of the tibial baseplate was the reason for revision in 25 retrievals, occurring at the implant-cement interface in 16 cases. Polishing was observed on the lower surface of the baseplate and correlated to the level of cobalt, chromium, and zirconium in the blood. No evidence of abnormally high polyethylene wear was present. For each 1 mm increase in cement thickness the odds of failure due to aseptic loosening decreased by 61%. Greater varus alignment was associated with a shorter time to failure. The roughness, Ra, of a new LCS baseplate's lower surface was 3.7 (SD 0.7) µm. Interpretation - Debonding of the tibial component at the implant-cement interface was the predominant cause of tibial aseptic loosening. A thin cement layer may partly explain the poor performance. Furthermore, the comparatively low tibial surface roughness and the lack of a keeled stem may have played a role in the failures observed. [ABSTRACT FROM AUTHOR]

Background and purpose — Hemiarthroplasty is the most common treatment in elderly patients with displaced femoral neck fracture. Prosthetic joint infection (PJI) is a feared complication. The infection rate varies in the literature, and there are limited descriptive data available. We investigated the characteristics and outcome of PJI following hemiarthroplasty over a 15-year period. Patients and methods — Patients with PJI were identified among 519 patients treated with hemiarthroplasty for a femoral neck fracture at Oslo University Hospital between 1998 and 2012. We used prospectively registered data from previous studies, and recorded additional data from the patients’ charts when needed. Results — Of the 519 patients, we identified 37 patients (6%) with early PJI. 20 of these 37 patients became free of infection. Soft tissue debridement and retention of implant was performed in 35 patients, 15 of whom became free of infection with an intact arthroplasty. The 1-year mortality rate was 15/37. We found an association between 1-year mortality and treatment failure (p = 0.001). Staphylococcus aureus and polymicrobial infection were the most common microbiological findings, each accounting for 14 of the 37 infections. Enterococcus spp. was found in 9 infections, 8 of which were polymicrobial. There was an association between polymicrobial infection and treatment failure, and between polymicrobial infection and 1-year mortality. Interpretation — PJI following hemiarthroplasty due to femoral neck fracture is a devastating complication in the elderly. We found a high rate of polymicrobial PJIs frequently including Enterococcus spp, which is different from what is common in PJI after elective total hip arthroplasty. [ABSTRACT FROM PUBLISHER]

Background. Surgical site infection (SSI) is a feared complication in hip arthroplasty, especially following femoral neck fracture in the elderly, associated with substantially increased morbidity, mortality, and costs. Gentamicincontaining collagen sponges are widely used for prevention of SSIs, but their effectiveness in joint replacement surgery remains unclear. Methods. We performed a multicenter, randomized trial between February 2011 and July 2013. Eligible patients with femoral neck fracture undergoing hemiarthroplasty were randomly assigned to receive either intravenous antimicrobial prophylaxis alone or with the addition of 2 gentamicin-containing collagen sponges into the hip joint perioperatively. The primary end point was SSI according to the Centers for Disease Control and Prevention criteria within 30 days after surgery. Results. Seven hundred thirty-nine patients were randomly assigned, 684 of whom were included in the modified intention-to-treat analysis. There was no statistical significant difference in SSI between the gentamicin-collagen group (16 of 329 patients [4.9%]) and the control group (19 of 355 patients [5.4%]) (relative risk [RR], 0.91 [95% confidence interval, .48-1.79]; P = .77). No significant differences were observed between the groups in superficial SSI (2 of 329 [0.6%] vs 3 of 355 [0.8%]; P = .99) and deep SSI (14 of 329 [4.3%] vs 16 of 355 [4.5%]; P = .87). There were no significant differences between the groups regarding type of bacteria isolated. Conclusions. Locally administered gentamicin-collagen sponges did not reduce the incidence of SSI in elderly patients treated with a hemiarthroplasty because of femoral neck fracture. [ABSTRACT FROM AUTHOR]

Objective: To examine whether the 1-year effects from a previous walking skill training program on walking and stair climbing still persist 5 years following total hip arthroplasty (THA), to examine recovery of physical functioning from before to 5 years after surgery, and to identify predictors of physical activity 5 years after THA from preoperative measures.Methods: We performed a 5-year followup of a randomized controlled trial and a longitudinal study. Sixty participants with a mean age of 70 years (range 50-87 years; 95% confidence interval 68, 72 years) were assessed. Outcome measures were the 6-minute walk test, the stair climbing test (SCT), active hip range of motion (ROM), self-efficacy, Hip Dysfunction and Osteoarthritis Outcome Score (HOOS), and University of California, Los Angeles (UCLA) activity scale. Data were analyzed by Student's t-tests, generalized linear model, and multivariate regression analyses.Results: The training and control groups were approximately equal on outcome measures of physical functioning, pain, and self-efficacy at 5 years (P > 0.05). In the total group, the recovery course was unchanged from 1 to 5 years (P > 0.05), except for 9% improvement in ROM (P < 0.001) and an increase in time on SCT of 18% (P = 0.004). Preoperative HOOS pain (P = 0.022) and HOOS sport (P = 0.019) predicted UCLA activity scale 5 years after THA.Conclusion: At 5 years after THA, the control group had caught up with the training group on physical functioning, and the participants led an active lifestyle. Those with worse preoperative scores on pain and physical functioning in sport were at risk of being less physically active in the long term following THA. [ABSTRACT FROM AUTHOR]- Published

Background and purpose Conversion total hip replacement (THR) is a common procedure after failed hemiarthroplasty, but there have been few reports describing the long-term outcome of this procedure. Patients and methods Between 1987 and 2004, 595 THRs were reported to the Norwegian Arthroplasty Register as conversion THR for failed hemiarthroplasty after a femoral neck fracture in patients aged 60 years and older. 122 operations left the femoral stem intact, whereas 473 were converted with exchange of the femoral stem. Results We found a lower risk of failure (revision surgery for any reason) for the conversion procedures with stem exchange (RR = 0.4; 95% CI: 0.25-0.81) than for the conversion procedures that retained the femoral stem. For the 473 conversion arthroplasties with exchange of the stem, we found no difference in risk of failure compared to all revision stems in the register, either for the complete prosthesis (RR = 0.8; CI: 0.50- 1.20) or for the stem (RR = 0.9; CI: 0.53-1.59). However, for the 122 conversion procedures in which the femoral stem was retained, we found a significantly increased risk of failure for both the complete prosthesis (RR = 4.6; CI: 2.8-7.6) and for the acetabular cup (RR = 4.8; CI: 2.3-10) compared to primary hip arthroplasties. Interpretation Our findings indicate that the seemingly easy operation of implanting an acetabular cup to convert a hemiarthroplasty to a total hip arthroplasty is an uncertain procedure and that the threshold for replacing the stem should be low.

Summary: We report 11 cases of interprosthetic dislocation of the Charnley/Hastings hemiarthroplasty in a retrospective study of 350 consecutive patients treated for an acute femoral neck fracture. We found a total of 14 dislocations (4.0%), 11 were interprosthetic. The median age of the 350 patients was 79 (36–99) years and the median age of the 11 patients with an interprosthetic dislocation was 85 years (82–94). The median time from surgery to radiologically acknowledged dislocation was 18 (4–64) days. These interprosthetic dislocations may be caused by either an assembly mistake perioperatively, by maximum angulation and impingement between the components, or by trauma. [Copyright &y& Elsevier]

Aim: To compare early complications after the posterior and the direct lateral (transgluteal) approach, when using hemiarthroplasty in the treatment of displaced femoral neck fractures in the elderly.Patients and Methods: A prospective clinical study from four Norwegian hospitals, consisting of 583 patients with 1year follow-up. All the hospitals used the same uncemented femoral stem and bipolar heads. Data were collected for gender, age, surgical approach, prosthetic dislocation, postoperative infection, perioperative fracture, duration of surgery, ASA score, diabetes, alcoholism, cognitive failure, BMI, 30-day mortality and 1-year mortality.Results: Mean age was 83 years (SD 7.8) and 434/583 (74%) were female. There were no relevant differences between the treatment groups. A higher risk was found for prosthetic dislocation in the posterior group compared to the lateral group (15/186 (8%) vs. 4/397 (1%); RR=8.0, 95% CI 2.7-23.8, p-value<0.001), both as a one-time event and for the risk of recurrent dislocations (9/186 (5%) vs. 2/395 (0.5%); RR 9.6, 95% CI 2.1-44.0, p-value=0.001). 11/19 patients with dislocation had recurrent dislocations. 10/11 patients with more than one dislocation needed further open surgery. Of those 6/10 needed more than one additional open procedure. Three patients had a resection arthroplasty and one patient had a chronic infection as final result after a dislocation. No other risk factor for dislocation than surgical approach was identified. There were no differences between the approach groups for other complications.Conclusion: There was an 8-fold increased risk for prosthetic dislocations after the posterior approach compared to lateral approach. There was a high risk for recurrent prosthetic dislocations and a subsequent risk for further surgeries and a poor end result. The potential advantages of the posterior approach have not been demonstrated after femoral neck fractures and we advise against its continued use. [ABSTRACT FROM AUTHOR]- Published

Background and Purpose: Incidence of posterior malleolar fractures (PMFs) associated with ankle fractures is historically based on plain radiographs. Several classification systems for PMF are currently in use, but the reliability of the Haraguchi classification is not reported. The aim of this diagnostic cohort study was to assess incidence of PMF in patients with AO 44-C fractures, and test the reliability of the Haraguchi fracture classification based on CT. In addition, to evaluate the clinical outcome in patients with PMF.Methods: 210 patients with an AO 44-C type fracture treated with syndesmotic fixation between 2011 and 2017 were included. Presence of PMF was registered, morphology was assessed and classified according to the Haraguchi classification. Interobserver agreement for the Haraguchi classification was evaluated. Patient assessment was conducted at 6 weeks, 6 months, 1 and 2 years. The American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score (AOFAS) was the primary outcome measure. Secondary outcome measures included presence of osteoarthritis.Results: 125 of 210 patients (60%) had a PMF. 34% of the PMFs were missed on plain radiographs compared to CT. The interobserver agreement was 0.797, (95% CI: 0.705 to 0.889, p < 0.001), for the Haraguchi classification. The 2-year follow-up rate was 86%. Haraguchi type II fractures had a lower AOFAS compared with the no-fracture group at 6 weeks (mean difference -7.5 (95% CI; -15.0 to -0.2), p = 0.04) and 6 months (mean difference -8.4 (95% CI; -15.3 to -1.5), p = 0.01). Presence of osteoarthritis was higher in patients with Haraguchi type II PMF compared to the no PMF group, this finding was not significant (relative risk (RR) 1.6(95% CI 1.1 to 2.4, p = 0.059)).Conclusions: Plain radiographs underestimated PMF. Patients with a Haraguchi type II fracture had a poorer outcome measured by the AOFAS score compared to no PMF up until 6 months. Classification of PMF according to the Haraguchi classification was reliable. [ABSTRACT FROM AUTHOR]- Published

Purpose: The aim of this study was to determine the rate of complications after routine syndesmotic screw removal.Materials and Methods: All patients who underwent syndesmotic screw removal at our hospital between 2007 and 2012 were included in the study. Patient demographics, surgical characteristics, radiographic evaluation and complications were recorded from the patients' charts. Questionnaires were sent by postal mail to all patients, to measure patient satisfaction and pain (VAS scales).Results: 161 patients were included in the trial. A wound infection was found in 8 (5%) patients. 3 were regarded as serious infections requiring hospitalisation and intravenous antibiotics, 2 of those required surgical revisions. 5 patients were treated by oral antibiotics. Staphylococcus aureus was identified as the causing organism in all (6/8) cases with a positive culture. The patients with postoperative infection reported more pain (5.3 vs. 2.3; p=0.02) and were less satisfied (4.7 vs. 7.6; p=0.014) with their ankle compared to those without infection (T-test for independent samples).Conclusion: There were 5% wound infections after routine syndesmotic screw removal. Routine antibiotic prophylaxis effective against S. aureus should be administered when removing syndesmotic screws. In our institution we now use one single dose Cefalotin of 2g intravenously 30-60min before screw removal. [ABSTRACT FROM AUTHOR]- Published

Eikrem M, Lian T, Madsen JE, and Figved W
- Abstract
Background The advantage of pronator quadratus (PQ) repair following internal fixation via the volar approach in distal radius fracture (DRF) surgery remains unconfirmed in the literature. The aim of this study was to compare grip strength, patient-reported outcomes, and functional results between patients with an intact PQ and those with a ruptured PQ before undergoing surgery with a volar locking plate for dorsally displaced unstable extra-articular DRFs. Methods A total of 120 patients aged 55 years and older were included in a randomized controlled trial comparing a volar locking plate with a dorsal nail plate. Of the 60 patients randomized to the volar plate group, the integrity of the PQ muscle was recorded during surgery for 55 patients, who were included in this study. The outcomes measured were the Quick Disabilities of the Arm, Shoulder, and Hand Outcome Measure (QuickDASH) score, the Patient-Rated Wrist Evaluation (PRWE) score, the EQ-5D index, the visual analog scale (VAS) score, grip strength, and range of motion (ROM). Results The median age was 67 years (range 55 to 88), and the one-year follow-up rate was 98%. Patients with an identified intact PQ (28/55) before surgical release had better QuickDASH scores after one year (2.5 vs 8.0, mean difference 5.5, 95% CI: 1.3 to 9.8, p=0.028). Patients in the intact group also had better EQ-5D Index scores after one year (0.94 vs 0.85, mean difference 0.089, 95% CI: 0.004 to 0.174, p=0.031), and demonstrated better grip strength throughout the trial; after one year: 24 kg vs 20 kg (mean difference 3.9; 95% CI: 0.3 to 7.6, p=0.016). After one year, the intact group had regained 96% of their grip strength and the nonintact group had regained 93% of their grip strength compared to the uninjured side. The observed differences may be of questionable clinical importance, as they were lower than those of previously proposed minimal clinically important differences (MCIDs). Conclusions Patients with a DRF and a ruptured PQ prior to surgery exhibited higher QuickDASH scores and lower EQ-5D index scores after one year. The integrity of the PQ should be reported in future studies., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Eikrem et al.)

- Abstract
Introduction: Surgery is widely recognised as the treatment of choice for suprasyndesmotic ankle fractures, because of the assumption that these injuries yield instability of the ankle joint. Stability assessment of ankle fractures using weightbearing radiographs is now used regularly to guide the treatment of transsyndesmotic and infrasyndesmotic ankle fractures. Patients with a congruent ankle joint on weightbearing radiographs can be treated non-operatively with excellent results. Weightbearing radiographs are, however, rarely performed on suprasyndesmotic fractures due to the assumed unstable nature of these fractures. If weightbearing radiographs can be used to identify suprasyndesmotic fractures suitable for non-operative treatment, we may save patients from the potential burdens of surgery.Our aim is to compare the efficacy of operative and non-operative treatment of patients with suprasyndesmotic ankle fractures that reduce on weightbearing radiographs., Methods and Analysis: A non-inferiority randomised controlled trial involving 120 patients will be conducted. A total of 120 patients with suprasyndesmotic ankle fractures with an initial radiographic medial clear space of <7 mm will be subjected to weightbearing radiographs. If the tibio-talar joint is completely reduced, we will randomise in a 1:1 ratio to either operative treatment including reduction and fixation of the syndesmosis or non-operative treatment with an orthosis. The primary study outcome is patient-reported ankle function and symptoms as measured by the Olerud-Molander Ankle Score at 2-year follow-up. Secondary outcomes include the Manchester-Oxford Foot Questionnaire, range of motion, radiographic results and rates of adverse events., Ethics and Dissemination: The Regional Committee for Medical and Health Research South East, group A (permission number: 169307), has granted ethics approval. The results of this study will provide valuable insights for developing future diagnostic and treatment strategies for a common fracture type.

- Abstract
Alterations in brain energy metabolism have long been proposed as one of several neurobiological processes contributing to delirium. This is supported by previous findings of altered CSF lactate and neuron-specific enolase concentrations and decreased glucose uptake on brain-PET in patients with delirium. Despite this, there are limited data on metabolic alterations found in CSF samples, and targeted metabolic profiling of CSF metabolites involved in energy metabolism has not been performed. The aim of the study was to investigate whether metabolites related to energy metabolism in the serum and CSF of patients with hip fracture are associated with delirium. The study cohort included 406 patients with a mean age of 81 years (standard deviation 10 years), acutely admitted to hospital for surgical repair of a hip fracture. Delirium was assessed daily until the fifth postoperative day. CSF was collected from all 406 participants at the onset of spinal anaesthesia, and serum samples were drawn concurrently from 213 participants. Glucose and lactate in CSF were measured using amperometry, whereas plasma glucose was measured in the clinical laboratory using enzymatic photometry. Serum and CSF concentrations of the branched-chain amino acids, 3-hydroxyisobutyric acid, acetoacetate and β-hydroxybutyrate were measured using gas chromatography-tandem mass spectrometry (GC-MS/MS). In total, 224 (55%) patients developed delirium pre- or postoperatively. Ketone body concentrations (acetoacetate, β-hydroxybutyrate) and branched-chain amino acids were significantly elevated in the CSF but not in serum among patients with delirium, despite no group differences in glucose concentrations. The level of 3-hydroxyisobutyric acid was significantly elevated in both CSF and serum. An elevation of CSF lactate during delirium was explained by age and comorbidity. Our data suggest that altered glucose utilization and a shift to ketone body metabolism occurs in the brain during delirium., (© The Author(s) 2023.

- Abstract
Introduction: Hip fractures are common, serious and costly fractures in the elderly population. Several guidelines seeking to ensure best practice have been introduced. Although our institution complied with national guidelines for early surgery of hip fractures, no assessment of other evidence-based measures existed. We wanted to assess, test, implement and measure the impact of a quality improvement (QI) programme consisting of key elements proven to be important in the treatment of hip fractures., Methods: We formed a multidisciplinary QI team, consisting of several specialists in different fields. The QI team assessed multiple possible process measures for inclusion in the programme and selected six measurable interventions for implementation: early surgery, correct administration of prophylactic antibiotics, surgery using proven methods and expertise, a multidisciplinary patient pathway and secondary fracture prevention. The improvement process was monitored by a statistical process control chart (SPC). Complications, reoperations and mortality were compared before (n=293) and after (n=182) the intervention., Results: The SPC analyses indicated increasing adherence with all interventions throughout the improvement programme, and sustainability 7 years later. The last four periods showed a stable adherence above 90%. We found 60% reduction in major complications after the implementation of the improvement programme, from 19.1% to 7.7% (HR: 0.38 (95% CI: 0.23 to 0.61, p=0.0007). The need for reoperations due to complications fell from 12.6% to 4.9% (HR: 0.37 (95% CI: 0.21 to 0.67, p=0.0054). We did not find a difference in post-operative mortality after the implementation of the QI programme (HR: 0.95 (95% CI: 0.74 to 1.2, p=0.645)., Conclusion: Our multiprofessional improvement programme achieved almost full adherence within 2 years and was sustainable 7 years later. The quality and safety of the care process were improved and led to a substantial and sustainable decrease in complications and reoperations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

- Abstract
The use of low-profile dorsal and volar locking plates for distal radial fracture surgery has improved results and lowered the complication rate compared with older plate designs. The purpose of the present randomized controlled trial was to compare patient-reported outcomes as well as radiographic and functional results between patients who underwent stabilization with a volar locking plate or a dorsal locking nail-plate for the treatment of dorsally displaced unstable extra-articular distal radial fractures., Methods: One hundred and twenty patients ≥55 years of age were randomized to surgery with either a volar locking plate or a dorsal locking nail-plate and were assessed at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. The primary outcome was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. Secondary outcomes were the Patient-Rated Wrist Evaluation (PRWE), EuroQol 5 Dimensions (EQ-5D) index and visual analog scale (VAS), range of motion, grip strength, radiographic measurements, and complication rate., Results: The median age was 66 years (range, 55 to 88 years). The rate of follow-up was 97%. There was no clinically important difference between the groups at any point during follow-up. Patients in the volar locking plate group had better mean QuickDASH scores at 6 weeks, 6 months, and 1 year. However, the differences were small (5.8 vs. 11.3 points at 1 year; mean difference, -5.5 points [95% confidence interval (CI), -9.9 to 1.2]; p = 0.014), which is lower than any proposed minimum clinically important difference (MCID). The difference in PRWE scores was also lower than the MCID (1.0 vs. 3.5 at 1 year; mean difference, -2.5 [95% CI, -4.4 to 0.6]; p = 0.012). The dorsal locking nail-plate group had slightly better restoration of volar tilt (p = 0.011). EQ-5D index, EQ-5D VAS, range of motion, grip strength, and complication rates were similar., Conclusions: We found no clinically relevant difference between the volar locking plate and dorsal locking nail-plate groups after 1 year or in the time period up to 1 year. A dorsal locking nail-plate can therefore be an alternative method for the treatment of these unstable fractures or in cases in which a dorsal approach is preferable over a volar approach., Level of Evidence: Therapeutic Level I.

- Abstract
Aims: In a randomized controlled trial with two-year follow-up, patients treated with suture button (SB) for acute syndesmotic injury had better outcomes than patients treated with syndesmotic screw (SS). The aim of this study was to compare clinical and radiological outcomes for these treatment groups after five years., Methods: A total of 97 patients with acute syndesmotic injury were randomized to SS or SB. The five-year follow-up rate was 81 patients (84%). The primary outcome was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale. Secondary outcome measures included Olerud-Molander Ankle (OMA) score, visual analogue scale (VAS), EuroQol five-dimension questionnaire (EQ-5D), range of movement, complications, reoperations, and radiological results. CT scans of both ankles were obtained after surgery, and after one, two, and five years., Results: The SB group had higher median AOFAS score (100 (interquartile range (IQR) 92 to 100) vs 90 (IQR 85 to 100); p = 0.006) and higher median OMA score (100 (IQR 95 to 100) vs 95 (IQR 75 to 100); p = 0.006). The SS group had a higher incidence of ankle osteoarthritis (OA) (24 (65%) vs 14 (35%), odds ratio (OR) 3.4 (95% confidence interval (CI) 1.3 to 8.8); p = 0.009). On axial CT we measured a significantly smaller mean difference in the anterior tibiofibular distance between injured and non-injured ankles in the SB group (-0.1 mm vs 1.2 mm; p = 0.016)., Conclusion: Five years after syndesmotic injury treated with either SB or SS, we found better AOFAS and OMA scores, and lower incidence of ankle OA, in the SB group. These long-term results favour the use of SB when treating an acute syndesmotic injury. Cite this article: Bone Joint J 2020;102-B(2):212-219.

- Abstract
Importance: Fragility fracture is a major health issue because of the accompanying morbidity, mortality, and financial cost. Despite the high cost to society and personal cost to affected individuals, secondary fracture prevention is suboptimal in Norway, mainly because most patients with osteoporotic fractures do not receive treatment with antiosteoporotic drugs after fracture repair., Objectives: To improve secondary fracture prevention by introducing a standardized intervention program and to investigate the effect of the program on the rate of subsequent fractures., Design, Setting, and Participants: Trial protocol of the Norwegian Capture the Fracture Initiative (NoFRACT), an ongoing, stepped wedge cluster randomized clinical trial in 7 hospitals in Norway. The participating hospitals were cluster randomized to an intervention starting date: May 1, 2015; September 1, 2015; and January 1, 2016. Follow-up is through December 31, 2019. The outcome data were merged from national registries of women and men 50 years and older with a recent fragility fracture treated at 1 of the 7 hospitals., Discussion: The NoFRACT trial is intended to enroll 82 000 patients (intervention period, 26 000 patients; control period, 56 000 patients), of whom 23 578 are currently enrolled by January 2018. Interventions include a standardized program for identification, assessment, and treatment of osteoporosis in patients with a fragility fracture that is led by a trained coordinating nurse. The primary outcome is rate of subsequent fracture (per 10 000 person-years) based on national registry data. Outcomes before (2008-2015; control period) and after (2015-2019; intervention period) the intervention will be compared, and each hospital will act as its own control. Use of outcomes from national registry data means that all patients are included in the analysis regardless of whether they are exposed to the intervention (intention to treat). A sensitivity analysis with a transition window will be performed to mitigate possible within-cluster contamination., Results: Results are planned to be disseminated through publications in peer-reviewed journals and presented at local, national, and international conferences., Conclusions: By introducing a standardized intervention program for assessment and treatment of osteoporosis in patients with fragility fractures, we expect to document reduced rates of subsequent fractures and fracture-related mortality., Trial Registration: ClinicalTrials.gov Identifier: NCT02536898.

- Abstract
Background: About 5000 people fracture their femoral neck every year in Norway. Mean age is about 83 years and about 3/4 are women. For more than 50 years the alternatives have been internal fixation or arthroplasty. In Norway, the tradition has been internal fixation. Recent studies, however, support the use of arthroplasty. The article provides a review on the treatment of femoral neck fractures., Material and Methods: The article is based on literature identified through a non-systematic search in Medline., Results: Internal fixation has a higher risk of treatment failure (30 - 40 % in displaced fractures) than arthroplasty (less than 10 %). In elderly patients with displaced fractures, arthroplasty provides better hip function than internal fixation. Most patients should be treated with hemiarthroplasty, but total hip arthroplasty may give better function in the healthiest and fittest of the elderly patients. In patients younger than 60 - 65 years, internal fixation should be attempted, even though the failure rate is about 30 %. Undisplaced fractures should be treated with internal fixation, irrespective of age. The risk of treatment failure is about 10 %., Interpretation: Elderly patients with displaced femoral neck fractures should be treated with arthroplasty, usually hemiarthroplasty. Osteosynthesis should normally be reserved for undisplaced fractures and fractures in young and otherwise healthy patients.
