- Background and purpose Hip fractures should be treated based on the best available evidence and cost-effectively to optimize the outcome for this large group of frail patients. This study examined nationwide variation in surgical methods used for hip fractures. Methods In this cohort study 46,243 patients >= 65 years with a trochanteric hip fracture (THF) or a femoral neck fracture (FNF) registered in the Swedish Fracture Register (SFR) between 1 January 2016 and 31 December 2020 were included. Fractures were classified according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) fracture classification system. The choice of surgical methods was assessed for each fracture type to compare national variation. Results 21,312 THFs and 24,072 FNFs (67% women) with a mean age of 83 years (SD 8) were surgically treated. In the treatment of two-fragment THFs (AO/OTA A1) departments ranged from using 90% short intramedullary nails to 98% sliding hip screws. Treating displaced FNFs (AO/OTA B3), the proportion of hemiarthroplasty ranged from 9 to 90%, and internal fixation between 0.6 to 21%, depending on the department. Interpretation A mature national fracture register permits the monitoring of treatment provided and thus serves as an important aid in assessing compliance with guidelines. The large inter-departmental variation in the surgical management of hip fractures in Sweden appears unwarranted based on the current evidence, indicating a need for updated national guidelines. Further research will have to clarify the impact of this variation on mortality and re-operation rates.

Journal article (peer-reviewed)abstract
- Purpose: To assess the possibility of using Generative Pretrained Transformer (ChatGPT) specifically in the context of orthopaedic trauma surgery by questions posed to ChatGPT and to evaluate responses (correctness, completeness and adaptiveness) by orthopaedic trauma surgeons.Methods: ChatGPT (GPT-4 of 12 May 2023) was asked to address 34 common orthopaedic trauma surgery-related questions and generate responses suited to three target groups: patient, nonorthopaedic medical doctor and expert orthopaedic surgeon. Three orthopaedic trauma surgeons independently assessed ChatGPT's responses by using a three-point response scale with a response range between 0 and 2, where a higher number indicates better performance (correctness, completeness and adaptiveness).Results: A total of 18 (52.9%) of all responses were assessed to be correct (2.0) for the patient target group, while 22 (64.7%) and 24 (70.5%) of the responses were determined to be correct for nonorthopaedic medical doctors and expert orthopaedic surgeons, respectively. Moreover, a total of 18 (52.9%), 25 (73.5%) and 28 (82.4%) of the responses were assessed to be complete (2.0) for patients, nonorthopaedic medical doctors and expert orthopaedic surgeons, respectively. The average adaptiveness was 1.93, 1.95 and 1.97 for patients, nonorthopaedic medical doctors and expert orthopaedic surgeons, respectively.Conclusion: The study results indicate that ChatGPT can yield valuable and overall correct responses in the context of orthopaedic trauma surgery across different target groups, which encompassed patients, nonorthopaedic medical surgeons and expert orthopaedic surgeons. The average correctness scores, completeness levels and adaptiveness values indicated the ability of ChatGPT to generate overall correct and complete responses adapted to the target group.

In: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 23:1
-
Journal article (peer-reviewed)abstract
- Background Before the creation of the Swedish Fracture Register (SFR), there was no national quality register that prospectively collects data regarding all types of fractures regardless of treatment in an emergency setting. Observational data on fractures registered in a sustainable way may provide invaluable tools for quality improvements in health care and research. Description Ten years after its implementation, the Swedish Fracture Register has 100% coverage among orthopaedic and trauma departments in Sweden. The completeness of registrations reached in 2020 69-96% for hip fractures at the different departments, with the majority reporting a completeness above 85%. The Swedish Fracture Register is a fully web-based national quality register created and run by orthopaedic professionals, with financial support from public healthcare providers and the government. All users have full access to both the registration platform and all aggregated statistics in real time. The web-based platform was created for use in health quality registers and it has easily gained acceptance among users. The register has gradually developed by the addition of more fracture types and skeletal parts. Research activity is high and 31 scientific publications have been published since 2016. The strategy from the start was to publish validation data and basic epidemiological data. However, over the past few years, publications on outcomes, such as re-operations and mortality, have been published and four register-based, randomised, controlled trials are ongoing. Conclusion It is possible to create a fracture register, to gain professional acceptance and to collect fracture data in a sustainable way on a national level if the platform is easy to use. Such a platform can also be used as a randomisation platform for prospective studies.

Classification and treatment of lateral malleolar fractures - a single-center analysis of 439 ankle fractures using the Swedish Fracture Register
- 2020

In: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 21
-
Journal article (peer-reviewed)abstract
- © 2020 The Author(s). Background: The decision regarding which trans syndesmotic ankle fractures to treat surgically and which to treat non-surgically is a matter of debate. The aim of this study was to describe the epidemiology of ankle fractures treated at Sahlgrenska University Hospital (SU) during a 2-year period and analyze the current diagnostic process, classification and choice of treatment for lateral malleolar fractures at the level of the syndesmosis. Methods: Observational data regarding all ankle fractures treated at SU between 1 April 2012 and 31 March 2014 was collected from the Swedish Fracture Register. For identified AO/OTA44-B1 fractures, medical records and radiographs were reviewed and analyzed. Results: The study included 1332 ankle fractures. 838 (63%) were B-fractures and 512 (38%) of these were B1 fractures. 439 of the patients with B1 fractures were included in the detailed study and of these 309 (70%) were treated non-surgically and 130 patients (30%) surgically. According to the preoperative physical examination described in the medical records, medial tenderness was found in 73 (24%) of the non-surgically treated patients. Among the surgically treated patients 18% (n = 24) were found to have no medial tenderness. For the non-surgically treated patients with medial tenderness, the treatment plan was changed to surgical treatment after the 1-week radiographic follow-up in 1 patient (1%) and 1 patient (1%) was treated surgically after 3 months due to non-union. Conclusions: The current study demonstrates the difficulty involved in distinguishing whether or not a trans-syndesmotic lateral malleolar fracture has an associated medial ligament injury or not. As this distinguishes if the fracture is stable or not it affects the choice of subsequent treatment. The results of the study also indicate a lack of consensus on how to classify and treat lateral malleolar fractures at the level of the syndesmosis. The study further suggests that there is no need to check non-surgically treated stable fractures with follow-up radiographic examination at 1 week.

Journal article (peer-reviewed)abstract
- Background and purpose - While many other countries implemented strict regulations and restrictions for their citizens during the 1st wave of the Covid-19 pandemic, Sweden maintained a more restrained approach. The Swedish Public Health Agency emphasized individual responsibility and pushed for behavioral changes. With strict lockdown a 77% decrease in ankle fracture incidence has been reported. We investigated whether there was a change in the incidence of ankle fractures seen at 7 selected hospitals during the Covid-19 pandemic 2020.Patients and methods - Data on all ankle fractures treated at 7 selected departments during March 15 through June 15, 2020, and for the same period in the preceding 3 years (2017-2019), was retrieved from the Swedish Fracture Register. The number of fractures during the whole period and subsequent 30-day periods were compared between 2020 and 2017-2019, including subgroup analyses of age and sex.Results - The monthly rate of ankle fractures was reduced by 14% in 2020 (139 fractures) compared with 2017-2019 (161 fractures). Women had a 16% decrease and patients aged > 70 years had a 29% decrease. During the 1st 30-day period, a 26% decrease in fractures was seen.Interpretation - During the 1st wave of the Covid-19 pandemic, a moderate decline in the number of ankle fractures was seen. Women and patients aged > 70 years displayed the greatest reduction. The greatest reduction in incidence of fractures was seen during the 1st 30-day period. This indicates greater adherence to government recommendations regarding social distancing in these subgroups and during the 1st month of the pandemic. Changes in ankle fracture incidence may be a measure of lockdown extent.

Journal article (peer-reviewed)abstract
- BackgroundDespite being one of the most common types of fracture, there is a lack of epidemiological studies involving ankle fractures of all kinds. Since 2012, the Swedish Fracture Register (SFR) has prospectively collected data on surgically and non-surgically treated ankle fractures. The aim of this study is to describe the epidemiology of ankle fractures between 2012 and 2022.MethodsAll ankle fractures registered in the SFR between 1 April 2012 and 31 March 2022 in patients aged 16 years or older were included. Information on age, sex, mechanism of injury, fracture classification according to AO/OTA and high- or low-energy trauma was retrieved from the SFR.ResultsDuring the study period, 56,439 patients sustained 57,443 ankle fractures. Women (61%) were more commonly affected than men (39%). The mean age at the time of injury was 55 years. Men were found to be younger at the time of injury compared with women. Women were found to sustain open fractures more frequently, whereas the men more frequently sustained high-energy trauma. The most common mechanism of injury for all ankle fractures and for each AO/OTA44 fracture group separately was a simple fall. A seasonal variation in ankle fractures was found, where the number of ankle fractures peaked during the between November and March.ConclusionsThis study presents the epidemiology of all AO/OTA types of ankle fractures. We have demonstrated that most ankle fractures are caused by a simple fall and occur during wintertime. Women are more commonly affected than men and are older at the time of injury. These findings indicate that age-related skeletal fragility, as well as an increasing risk of simple falls in the elderly, may be risk factors for ankle fractures. This study will contribute to the planning of primary prevention for ankle fractures.

Fractures of the lateral malleolus - a retrospective before-and-after study of treatment and resource utilization following the implementation of a structured treatment algorithm
- 2022
-
In: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 23:1
-
Journal article (peer-reviewed)abstract
- Background In 2015 a study of isolated lateral malleolar fractures (AO/OTA44-B1) treated at Sahlgrenska University hospital (SU) during two consecutive years revealed large-scale variation in the choice of treatment and planned follow-up. The study resulted in the development of a structured treatment algorithm (TA) for ankle fractures. We investigated the effects of this well-implemented TA on the classification, treatment and follow-up of lateral malleolar fractures. Methods The current study is an uncontrolled, non-randomized, retrospective before-and-after study comparing a group of AO/OTA44-B1 fractures treated at SU before the introduction of the TA for ankle fractures (1 April 2012 to 31 March 2014) with a group treated after the introduction of the TA (1 September 2017 to 31 August 2019). Results In all the studied parameters regarding treatment for AO/OTA44-B1 fractures, a statistically significant change was seen after the introduction of the TA. Surgical treatment reduced from 32% (95% CI 27.5 - 36.5) pre-TA to 10% (95% CI 6.9 - 13.1) post-TA, while the number of patients permitted full weight-bearing increased from 41% (95% CI 36.3 - 45.7) to 84% (95% CI 80.1 - 87.9). Conclusions A thoroughly implemented treatment algorithm can reduce the number of surgical treatments for stable ankle fractures. The current study demonstrates that a structured treatment algorithm can standardize the management of ankle fractures and make decisions less dependent on the surgeon's discretion.

Incidence and Risk Factors for Surgical Site Infection in Ankle Fractures: An Observational Study of 480 Patients in Sweden
- 2023
-
In: Journal of Clinical Medicine. - 2077-0383. ; 12:20
-
Journal article (peer-reviewed)abstract
- Introduction: Surgical site infection (SSI) is a frequently reported complication after ankle fracture surgery. To our knowledge, no study has been conducted on its incidence in Sweden. The present study aimed to determine the incidence of, risk factors for, and most common causative pathogen of SSI. Methods: Patients who underwent primary surgery for an ankle fracture between 1 September 2017 and 31 August 2019 at the Sahlgrenska University Hospital were identified. Data on potential SSI risk factors and clinical outcome (infected/non-infected) were retrieved from medical records. Cox regression analysis and descriptive statistics were used. Results: Of the 480 reviewed patients, 49 developed SSI (10.2%), of which 35 (7.3%) were superficial and 14 (2.9%) were deep. Open fractures (p < 0.001) and age (p = 0.016) were statistically significant risk factors for SSI in the univariate analysis. In the multivariable analysis, only open fracture was statistically significant (HR = 3.0; 95% C.I. = 1.3-6.9, p = 0.013). Cases of Staphylococcus aureus (S. aureus) were most common (n = 12, 24.5%). Methicillin resistance was uncommon (n = 2, 4.1%). Conclusions: An incidence of 10.2% was established, which is comparable to international findings. Infection monitoring is an important part of tackling the global challenge of antibiotic resistance. Future prospective studies to further establish risk factors are warranted to decrease the incidence of SSI.

Knowledge support for ankle fractures in the Swedish Fracture Register - a qualitative study of physicians' experiences
- 2022
-
In: Bmc Health Services Research. - : Springer Science and Business Media LLC. - 1472-6963. ; 22:1
-
Journal article (peer-reviewed)abstract
- Background The aim of this study is to investigate the experiences of physicians presented with a knowledge support system while registering data on ankle fractures in the Swedish Fracture Register. The present study aims to answer the following research questions: center dot "How is receiving knowledge support while registering a fracture in the Swedish Fracture Register experienced by the physicians using it?". center dot "Can a feeling of increased usability of a quality register be achieved by providing the user with real-time feedback?". Methods A total of 20 physicians using the Swedish Fracture Register were recruited using a purposive sampling strategy. Qualitative content analysis was performed on individual semi-structured interviews performed in May and June 2020. Results The present study demonstrates that the knowledge support system in the Swedish Fracture Register was perceived by the physicians as strengthening the evidence base and improving the quality of ankle fracture treatment. The knowledge support system was evaluated as a good tool for validating clinical decisions and managing the information that needs to be processed to make informed decisions. Conclusions The present study affirms that being provided with knowledge support is appreciated by physicians, increase value for work and enhance the initiative to register. The physicians experienced that the knowledge support provided an appreciated validation of the clinical decisions taken and a feeling of improved care. When incorporating knowledge support into an NQR, consideration must be given to physicians' fears of becoming overly reliant on a template and losing control of the clinical base.
