| Objective: Mayo Type II olecranon fracture can be treated by three internal fixation methods: locking compression plate,Kirschner-wire(Kwire)tension band fixation and suture anchor,for which the clinical efficacy of the three treatments were analyzed retrospectively,which can provide theoretical and practical basis for the selection of internal fixation method for olecranon fracture.Moreover,it is expected to provide a certain foundation for the clinical treatment of Mayo Type II olecranon fracture based on this study.Methods: A total of 77 patients with olecranon fracture admitted to the hospital from March 2016 to December 2022 were enrolled as the subjects of study.According to the different internal fixation methods,it was divided into three groups,Group A: 30 patients with internal fixation of locking compression plate were included,including 24 male cases and 6female cases,aged 18～64 years old;Group B: 15 patients with internal fixation of K-wire tension band were included,including 13 males and 2females,aged 18～74 years old;Group C: 32 patients with internal fixation of suture anchors were included,including 23 males and 9 females,aged20～83 years old.It was divided into two groups based on Mayo classification: 31 cases of Type IIA and 46 cases of Type IIB.According to the causes of injury,there were three groups: 23 cases for car accident,12 cases for fall injury,and 42 cases for fall injury.The general data of the three groups of patients were statistically analyzed,and no significant statistical differences(P>0.05)were found,which suggested that the data were comparable,and the data on the time required for surgery,incision length,per-operative blood loss,fracture healing time,average hospital stay and hospitalization cost,postoperative efficacy,postoperative VAS pain score,and incidence of postoperative complications were collected.Moreover,the clinical efficacy and treatment cost of the three internal fixation methods were compared by the appropriate statistical software.P<0.05 was deem as statistically significant difference.Results: The results demonstrated that there were significant differences in the time,incision length and blood loss among the three groups(P<0.05).Moreover,the time,incision length and blood loss in Group C were significantly lower than those in Group A and Group B(P<0.05).There was no significant difference among the three groups(P>0.05)in the comparison of the fracture healing time(P<0.05).Compared with the average length of stay and hospital cost,there were significant differences between the three groups.Compared with Group A or Group B,Group C had a significant reduction in mean length of hospital stay and hospital cost(P<0.05).There was no significant difference in efficacy between the three groups(P>0.05).However,there was a higher rate of excellence in Group C.There were statistically significant differences in VAS pain score and postoperative complication rate(P<0.05).Compared with Group A or Group B,there were fewest complications in Group C.Conclusion: Three internal fixation methods: locking compression plate,K-wire tension band internal fixation and suture anchor nails can be used for the treatment of olecranon fracture of Mayo Type II.Compared with the internal fixation method of locking compression plate and K-wire tension band,the internal fixation method of suture anchors has a short hospital stay,low cost,short operation time,less trauma,less peroperative bleeding,shortened fracture healing time,good postoperative elbow joint function recovery and the significant curative effect,which is worthy of wide clinical application.For Mayo Type II olecranon fractures,the internal fixation with suture anchors is recommended. |
