Patients were randomized in two groups: the cemented group (CHA, n=79) was treated with cement and the uncemented group (UCH, n=79) without cement. The groups were compared for operating time, blood loss and peroperative morbidity and mortality rates.\n\nResults: Both the CHA and the UCH group did not differ significantly in terms of age (86\u00b15 vs. 84\u00b14 years), sex (58.3% male vs. 60.7% female), and comorbidities (p=0.49). The CHA group had a significantly longer operating time (p=0.038) and a greater intraoperative blood loss (p=0.024). In the CHA group there were 8 (10.1%) events of intraoperative drop in the oxygen saturation (SaO2), whereas no such events were noted in the UCH group (p=0.009). Despite no significant difference between these two groups, we found that the CHA group was associated with a higher early postoperative mortality (8.8% in the CHA group versus 3.8% in the UCH group, p=0.009). Intraoperative fracture occurred in two patients (2.5%) of the UCH group. Over a 2-year follow-up period there were no significant differences between the groups regarding the rate of dislocation (p=0.56) or rate of postoperative periprosthetic fracture (p=0.56). There was a trend towards a better postoperative functional recovery at 6 week for the CHA group (77.1\u00b113.1 versus 71.3\u00b116.3), although the mean Harris Hip Score (HHS) at the end of 2 years was comparable (p=0.55).\n\nConclusion: Both CHA and UCH are acceptable methods for treating displaced femoral neck fractures. However, based on our results perioperative cardiovascular disturbances are less frequent and resulting in a potential lower early mortality with UCH. Therefore, UCH is particularly appropriate for elderly patients with pre-existing cardiovascular comorbidities.\n\nLevel of Evidence: Level II, Randomized Controlled Trial\n\nCite this article as: Movrin I.
