Comparison of all suture fixation with tension band wiring and plate fixation of the olecranon

Abstract

Background

Tension band wiring and plate fixation are common techniques used to stabilize simple olecranon fractures and osteotomies of the olecranon. All suture fixation is an alternative technique but has not been compared previously to these traditional methods. The aim of this study was to compare the clinical and radiographic outcomes of the three techniques.

Methods

One hundred and sixty-eight consecutive Mayo type 1 and 2 olecranon fractures (n = 138) and olecranon osteotomies (n = 30) with a minimum follow-up time of one year were compared. The primary outcome measure was the rate of re-operation. Secondary outcome measures were the incidence of complications, rate of radiographic union and incidence of radiographic reduction loss.

Results

Fixation was performed using tension band wiring in 89 patients, plating in 38 patients and suture fixation in 41 patients. There was no significant difference in the fracture type according to the Mayo classification between the groups. The re-operation rate was significantly higher in the tension band wiring group (36%) compared with both the plate group (11%, p = 0.03) and the suture group (2%, p = 0.002). There were two revision fixations in the tension band wiring group and one in the suture group. There was one asymptomatic non-union in the suture group. All other fractures and osteotomies achieved radiographic union.

Conclusion

Suture fixation of simple olecranon fractures and osteotomies was reliable in providing stable union and had a significantly lower re-operation rate when compared with tension band wiring.
