Novel Triangular Anchor Reduction Forceps versus Towel Forceps for Long Oblique or Spiral Distal Tibial Fractures: A Comparative Study

Abstract

Objective: To compare the efficacy of triangular anchor repositioning forceps and scarf forceps in the treatment of long oblique or spiral distal tibial fractures with intramedullary nailing. Methods: Finally, 58 patients were included. According to the intraoperative repositioning method, they were divided into the scarf clamp repositioning group (n=26) and the triangular anchor repositioning group (n=32). The operative time, a number of intraoperative fluoroscopies, intraoperative bleeding, quality of postoperative fracture reduction, length of hospital stay, fracture healing time, American orthopedic foot and ankle society (AOFAS) score, efficacy and complications at the last follow-up were compared between the two groups. Results: All patients participated in more than 1 year of follow-up. ①There were no significant differences in the composition ratios of age, sex, underlying disease, and mechanism of injury between the two groups; ②The operating time and intraoperative fluoroscopy number of patients in the triangular anchor reduction group were significantly lower than those in the scarf clamp reduction group (P<0.05), while the quality of fracture reduction was higher than that in the scarf clamp reduction group (P<0.05), and the differences in the remaining perioperative indexes were not significant; ③Patients in the triangular anchor reduction group had shorter postoperative fracture healing time and better ankle function than those in the scarf clamp reduction group (P<0.05); ④Patients in the two groups had various There was no significant difference in the incidence of various complications between the two groups, but the overall complication rate was significantly lower in the triangular anchor reduction group (P<0.05). Conclusion: The use of triangular anchor repositioning forceps can improve the quality of fracture repositioning, shorten fracture healing time, reduce the occurrence of complications, reduce the operative time and the number of intraoperative fluoroscopies, and no significant increase in local infection was observed, which is an effective and reliable repositioning method.
