HA for unstable IT fractures in elderly patients provides clinical results and 1-year survival comparable to HA for displaced FN fractures in the same aging group.
We identified 80 patients aged 75 years or older, who underwent cementless bipolar HA for unstable IT fracture (AO/OTA type 31-A2.2/3 and A3.3). Their clinical results and 1-year survival were compared to the matched control group of 80 patients with displaced FN fractures (Garden type 3 and 4) treated with the same procedure. Perioperative results, postoperative complications, and 1-year survival were investigated between the two groups. Functional outcome was assessed by walking status and Harris hip score (HHS) 6 months after surgery.
Operating time was significantly longer in the IT group than the FN group (97.3 min [50 to 255] vs. 79.3 min [40 to 175], P = 0.016). However, the two groups did not significantly differ regarding perioperative results such as total blood loss, transfusion, intraoperative fracture, length of hospital stay, and postoperative complication. No statistically significant differences in walking status and HHS were observed between the groups. No significant difference in cumulative survival was observed between the two groups (P = 0.836), with a 1-year survival rate of 80% (95% confidence interval [CI], 71.8 to 87.5) in the IT group and 82% (95% CI, 73.1 to 89.4) in the FN group.
HA for unstable IT fractures in elderly patients showed clinical results and 1-year survival comparable to HA as the treatment of choice for displaced FN fractures in the same aging group.
