Abstract Background Surgical treatment of pelvic and acetabular fractures is an advanced intervention with a high risk of subsequent complications. These patients are often polytrauma patients with multiple injuries in several organ systems. The optimal timing for the definitive surgery of these fractures has been debated. The primary aim of this study was to investigate the influence of timing of definitive surgery on the rate of unplanned reoperations. Secondary aims included its influence on the occurrence of adverse events and mortality. Methods All patients from 18 years with a surgically treated pelvic or acetabular fracture operated at the Karolinska University Hospital in Sweden during 2010 to 2019 were identified and included. Data was collected through review of medical records and radiographs. Logistic regression analysis was performed to evaluate factors associated with unplanned reoperations and other adverse events. Results A total of 419 patients with definitive surgical treatment within 1 month of a pelvic (n = 191, 46%) or an acetabular (n = 228, 54%) fracture were included. The majority of the patients were males (n = 298, 71%) and the mean (SD, range) age was 53.3 (19, 18–94) years. A total of 194 (46%) patients had their surgery within 72 h (early surgery group), and 225 (54%) later than 72 h (late surgery group) after the injury. 95 patients (23%) had an unplanned reoperation. There was no difference in the reoperation rate between early (n = 44, 23%) and late (n = 51, 23%) surgery group (p = 1.0). A total of 148 patients (35%) had any kind of adverse event not requiring reoperation. The rate was 32% (n = 62) in the early, and 38% (n = 86) in the late surgery group (p = 0.2). When adjusting for relevant factors in regression analyses, no associations were found that increased the risk for reoperation or other adverse events. The 30-day mortality was 2.1% (n = 4) for the early and 2.2% (n = 5) for the late surgery group (p = 1.0). The 1-year mortality was 4.1% (n = 8) for the early and 7.6% (n = 17) for the late surgery group (p = 0.2). Conclusions Early (within 72 h) definitive surgery of patients with pelvic or acetabular fractures seems safe with regard to risk for reoperation, other adverse events and mortality.

Background and purpose — Fractures of the pelvis and femur are serious and potentially lethal injuries affecting primarily older, but also younger individuals. Long-term trends on incidence rates and mortality might diverge for these fractures, and few studies compare trends within a complete adult population. We investigated and compared incidence and mortality rates of pelvic, hip, femur shaft, and distal femur fractures in the Swedish adult population. Patients and methods — We analyzed data on all adult patients ≥ 18 years in Sweden with a pelvic, hip, femur shaft, or distal femur fracture, through the Swedish National Patient Register. The studied variables were fracture type, age, sex, and 1-year mortality. Results — While incidence rates for hip fracture decreased by 18% (from 280 to 229 per 105 person-years) from 2001 to 2016, incidence rates for pelvic fracture increased by 25% (from 64 to 80 per 105 person-years). Incidence rates for femur shaft and distal femur fracture remained stable at rates of 15 and 13 per 105 person-years respectively. 1-year mortality after hip fracture was 25%, i.e., higher than for pelvic, femur shaft, and distal femur fracture where mortality rates were 20–21%. Females had an almost 30% lower risk of death within 1 year after hip fracture compared with males. Interpretation — Trends on fracture incidence for pelvic and femur fractures diverged considerably in Sweden between 2001 and 2016. While incidence rates for femur fractures (hip, femur shaft, and distal femur) decreased or remained constant during the studied years, pelvic fracture incidence increased. Mortality rates were different between the fractures, with the highest mortality among patients with hip fracture.

Background and purpose — The incidence of manipulation under anesthesia (MUA) after knee arthroplasty surgery has been reported to vary between 0.5% and 10%. We evaluated the incidence of MUA after primary knee arthroplasty in Sweden, the demographics of the patients and the risk of revision. Patients and methods — Between 2009 and 2013, 64,840 primary total and unicompartmental knee arthroplasties (TKA and UKA) were registered in the Swedish Knee Arthroplasty Register (SKAR). MUAs performed between 2009 and 2014 were identified through the in- and outpatient registers of the Swedish National Board of Health and Welfare. Pertinent data were verified through medical records and patient demographics and revisions were obtained from the SKAR. Results — 1,258 MUAs were identified. Of these, 1,078 were 1st-time MUAs, performed within 1 year after the primary knee arthroplasty. The incidence of MUA was 1.7% and the incidence varied between hospitals from 0% to 5%. The majority were performed after TKA (98%), in younger patients (65% < 65 years), women (64%), and relatively healthy persons (88% had ASA ≤ 2). The cumulative risk of revision at 10 years was 10% (95% CI 8.6–12), similar for men and women. Interpretation — In Sweden, MUA is a rather uncommon measure after knee arthroplasty, especially after UKA. The CRR at 10 years was doubled compared to the general knee arthroplasty population. The frequency of the procedure varies between hospitals but in general it is performed more frequently in healthier and younger patients.
