Abstract:
Objective:To investigate the clinical efficacy of locking proximal femur plates (LPFP) revision and artificial hip joint revision after failure of proximal femoral nail antirotation (PFNA) internal fixation in elderly patients with intertrochanteric fracture.Methods:A retrospective case control study was conducted on the clinical data of 43 patients with PFNA internal fixation failure in the elderly admitted to Henan Provincial People's Hospital between March 2014 and October 2018. There were 23 males and 20 females, aged 65-83 years [(71.2±2.0)years]. The course of disease was 60-267 days [(83.1±3.6)days]. According to Evans classification, there were 11 patients with type II fractures, 13 with type III and 19 with type IV. There were 23 patients in artificial hip joint revision group and 20 patients in LPFP revision group. The operation time, intraoperative blood loss, postoperative hospitalization time, total hospitalization time, Harris score and complications were recorded and evaluated in two groups.Results:All patients were followed up for 12-28 months, with an average of 13.6 months. Between artificial joint revision group and LPFP revision group, the operation time and intraoperative blood loss were similar ( P>0.05), but there were significant difference in postoperative hospitalization time [(7.1±3.2)days vs. (13.2±2.9)days] and total hospitalization time [(10.2±2.8)days vs. (16.4±3.4)days] ( P<0.05). In artificial joint revision group, the Harris hip score was (21.1±3.7)points preoperatively, and was respective (70.7±4.8)points, (74.6±4.1)points, (78.6±3.3)points, (82.9±5.2)points, (83.8±5.8)points and (84.9±6.4)points at postoperative 1, 2, 3, 6, 9, 12 months. In LPFP revision group, the Harris score was (21.7±3.2)points preoperatively, and was respective (59.9±2.1)points, (64.79±3.4)points, (70.1±4.2)points, (73.9±4.2)points, (76.2±6.3)points and (77.9±6.8)points at postoperative 1, 2, 3, 6, 9, 12 months. The Harris score in artificial joint revision group was gradually improved compared with LPFP revision group ( P<0.05). One patient with superficial wound infection occurred in each group, and the wound healed after frequent dressing changes. Distal femoral fractures occurred in one patient of artificial joint revision group and distal femoral fractures in three patients of LPFP revision group, but all patients were healed after being fixed with wire. Conclusion:For elderly patients with PFNA internal fixation failure of intertrochanteric fracture, artificial hip revision has shorter hospital stay and better hip joint function recovery than LPFP internal fixation, although the effect in operation time and intraoperative blood loss are similar.
