Introduction: The majority of all proximal humeral fractures (PHFs) are treated non-surgically. Due to the risk of early secondary fracture displacement patients with non-surgically treated PHFs routinely undergo serial clinical and radiological evaluations. However, the value of these routine follow-up visits is unclear. This study aimed to examine the rate of early conversion to surgery in non-surgically treated PHFs. Moreover, the associations between patient and fracture characteristics and the risk of conversion to surgery were explored in order to assess the need for routine follow-ups., Methods: Data on all patients aged ≥18 years with a non-surgically treated PHF registered between 2013 and 2021 were extracted from the Swedish Fracture Register. Early change of treatment from non-surgical to surgical is an optional treatment modality in the SFR. The rate of early conversion to surgery within 60 days from injury was analyzed in relation to age and sex of the patient, energy level at injury and fracture morphology according to the AO/OTA classification., Results: A total of 31,761 primarily non-surgically treated PHFs (mean age 70 years: 76 % female) were included in the study. The overall rate of early conversion to surgery was 3.7 %. Younger age and increasing fracture severity were associated with a higher conversion rate to surgery. Patients ≥80 years and those with the three most common fracture types (A1, A2, and B1) had <2 % early conversion to surgery. In contrast, patients with C-type fractures, unstable/displaced fractures (A3, B2, and C2), or fracture dislocations (A1.3, B3, and C3) had a substantially higher risk (5.0-20 %) of early conversion., Conclusion: The overall risk of early conversion to surgery in non-surgically treated PHFs is low and can be further predicted based on patient age and fracture morphology. These results could have implications regarding which patients are in need of routine follow-ups., Level of Evidence: Level II; Retrospective design; Prognosis study., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Objectives: To investigate the association between choice of treatment and patients' income after cruciate ligament (CL) injury and assess the effect of different covariates such as sex, age, comorbidities and type of work., Methods: This entire-population cohort study in Sweden included working patients with a diagnosed CL injury between 2002 and 2005, identified in The National Swedish Patient Register (n = 13,662). The exposure was the treatment choice (operative or non-operative treatment). The main outcome measure was average yearly income five years after CL diagnosis, adjusted for the following covariates: sex, age, comorbidities, type of work, region, calendar year, education and income., Results: Relative to non-operative treatment, operative treatment was associated with greater average yearly incomes (nine to 15%) after injury among patients between 20 and 50 years, patients with partial university education, patients living in large cities and patients with one comorbidity, despite no overall significant association in the national cohort. Delayed operative treatment (>1 year) had no significant association with income change, whereas early operative treatment (<1 year) was associated with higher average yearly incomes (11 to 16%) among females, patients between 20 and 50 years, patients living in large cities and patients with one comorbidity., Conclusions: In a broad sense, treatment choice was not associated with changes in income five years after CL injuries among patients in the workforce, however earlier operative treatment was associated with higher average incomes among patients with ages between 20 and 50, females, living in large cities, with one comorbidity and with a high level of education., (Copyright © 2019 Elsevier B.V.
