Abstract
Background: Percutaneous screw fixation has increasingly been used for pelvic ring fracture fixation. In older adult patients, especially in patients with a fragility fracture of the pelvis (FFP), minimally invasive techniques followed by early ambulation have been promoted in order to regain pre-injury levels of mobility and independence. The purpose of this study was to evaluate patient-centered outcomes, including post-operative pain relief, functional performance, and satisfaction, in older adults with pelvic ring fractures treated with percutaneous screw fixation and to assess injury characteristics, complications, and return-to-home rates. Methods: In this retrospective cohort study, patients 50 years and older who had their pelvic fracture treated in the Amsterdam UMC location AMC between January 2019 and December 2022 were identified. After a minimum follow-up period of 6 months, a questionnaire was conducted by phone to evaluate the pain, current living situation, and mobility of the patients. Results: A total of 51 patients were included in this study with a median age of 74 years (IQR 62-82), and the vast majority were female (n = 40, 78%). Over half of the pelvic fractures were caused by low-energy trauma (n = 29, 57%). Unilateral or bilateral sacral fractures with unilateral anterior ring fractures were the most common fracture pattern. The interoperative complication rate was 4%, and the in-hospital complication rate was 23%. Forty-five patients were reached to complete the questionnaire. Forty patients (91%) returned to an acceptable level of mobility after treatment, and almost all (n = 44, 98%) were pleased with the results of the surgery. Conclusions: Percutaneous screw fixation of pelvic fractures in older adult patients is a safe and effective operating technique. Most patients preserve their pre-morbid functionality and are able to return to their previous place of residence after admission. Furthermore, patients are almost unanimously very pleased with the results of the surgery despite some residual pain complaints.
