Abstract:

Objective To analyze the clinical efficacy and safety off emoral head replacement（FHR） assisting by the traction table in direct anterior approach（DAA）for the treatment of femur neck fractures in gerontal patients. Methods A retrospective analysis was conducted on 79 elderly patients who under went FHR for femoral neck fractures from March 2019 to July 2020.A total of 42 patients underwent FHR through DAA by using traction table were assigned to the observation group and 37 patients receiving FHR through the PLA to the control group. The perioperative data， follow-up results and complications were compared between the two groups. Results The observation group was significantly superior to the control group in intraoperative blood loss（P < 0.05）， where as the former was inferior to the latter in preoperative preparation time （P < 0.05）. There was no significant difference in anesthesia time and operation time between the two groups （P > 0.05）. The observation group resumed first postoperative standing time， partial-weight bearing walking time and full-weight bearing walking time significantly earlier than control group （P < 0.05）. Harris score at 1 month after the operation in the observation group were significantly higher than that of the control group（P < 0.05）， whereas which became not statistical significant between the two groups in 6 months and 1 year（P > 0.05）. No significant difference was found between the two groups for the incidence of complications（P > 0.05）. Conclusion DAA-FHR assisting by the traction table for the treatment of femur neck fractures in the elderly was effective and safe， but the preoperative preparation time was longer.
