AbstractWe aimed to compare the clinical and surgical outcomes of cemented vs uncemented bipolar hemiarthroplasty in the treatment of femoral neck fractures in the elderly. Patients (n = 99) without preoperative cardiopulmonary problems undergoing bipolar hemiarthroplasty for femoral neck fracture between August 2015 and February 2019 were randomly divided into cemented (group C) and uncemented (group U) stem fixation groups. Mean operative time, mean intraoperative blood loss, and percentage of intraoperative use of vasopressors, pre- and postoperative activities of daily living (ADL), incidence of postoperative complications, and radiological evaluation of stem alignment were evaluated. A total of 99 patients were included (group C, n = 42; group U, n = 57). Group C had a significantly longer mean operative time (P < .001) and a significantly higher percentage of intraoperative vasopressor use as compared to group U (P < .05). In contrast, the amount of intraoperative blood loss was similar between the 2 groups (P = .30). Likewise, there was no statistically significant difference in pre- and postoperative ADL performance between the groups (P = .70 and .44, respectively). Postoperative computed tomography revealed that stem anteversion was higher in group C than in group U (P < .05). Cemented and uncemented stems were equivalent in terms of blood loss and postoperative complications in patients with femoral neck fractures. Uncemented stem showed advantages in reducing operative time and intraoperative vasopressor administration. Also, fixation method was not investigated in this study.Copyright © 2024 the Author(s).
