| Objective To observe the clinical effect of InterTAN nail combined with 3D printing in the treatment of unstable femoral intertrochanteric fracture. Methods The clinical data of 40 patients diagnosed with unstable intertrochanteric fracture in the Second Affiliated Hospital of Bengbu Medical College from January 2017 to December 2018 were retrospectively analyzed. According to the different treatment methods, they were divided into group A and group B, with 20 cases in each group. Group A was treated with InterTAN nail combined with 3D printing, and group B with proximal femoral anti-rotation intramedullary nail(PFNA).The operation time, intraoperative blood loss, postoperative time to ground, fracture healing time, postoperative complications and Harris score were observed and compared between the two groups. Results There were no significant differences in operation time, intraoperative blood loss and fracture healing time between the two groups(P>0.05).The mean postoperative time to ground was (14.12±3.43)d in group A and (21.42±2.81)d in group B, and the difference was statistically significant(P<0.05).The incidence of postoperative complications in group A was 5.00%,lower than that in group B, and the difference was statistically significant(P<0.05).In the last follow-up, the Harris score in group A was(89.08±5.37),higher than that of group B, and the difference was statistically significant(P<0.05).The difference in Harris score between the two groups before and three days after surgery was statistically significant(P<0.05). Conclusions InterTAN nail combined with 3D printing in the treatment of unstable intertrochanteric fracture can provide better stability, early postoperative landing, fewer complications, and it significantly improves hip function. The therapeutic effect of InterTAN nail is better than that of PFNA, which is worthy of clinical promotion. |
