Abstract:
Objective:To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures.Methods:A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups.Results:The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences ( P<0.05). While the length of hospital stay was 12.35±4.81 d vs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups ( P>0.05). One-year mortality rates was 5.3% vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups ( P>0.05). Conclusion:Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.
